Objective To investigate the effectiveness of double-needle suture for mixed meniscus tear repair under arthroscope. Methods Between April 2006 and January 2011, 22 patients with mixed meniscus tear were treated with double-needle suture under arthroscope. There were 14 males and 8 females, aged 18-41 years (mean, 31.3 years). All injuries were caused by sports. The time between injury and admission ranged from 2 days to 4 years (median, 11 months). International Knee Documentation Committee (IKDC) score was 42.5 ± 15.2, Lysholm score was 45.5 ± 13.5, and Tegner score was 2.9 ± 1.6. Seventeen cases complicated with anterior cruciate ligament injury. Results Healing of incision by first intention was achieved in all patients. No injury of nerve and blood occurred. The patients were followed up 12-48 months with an average of 27.6 months. According to Barrett et al. standard, 19 cases (86%) got clinical healing. The IKDC, Lysholm, and Tegner scores were improved to 77.1 ± 8.9, 79.8 ± 9.9, and 6.8 ± 1.6 respectively at last follow-up, showing significant differences when compared with preoperative scores (P lt; 0.05). Conclusion Arthroscopic meniscus repair using double-needle suture can provide good effectiveness because it has high firmness.

ObjectiveTo investigate the application value of the intravenous indwelling needle in radionuclide imaging examination. MethodsA total of 120 patients underwent single photon emission computed tomography for bone and kidney dynamic imaging between October 2012 and April 2013 were randomly divided into group injected by venous indwelling needle (observagtion group) and group injected by traditional steel needle (control group), with 60 cases in each. We calculated the one-time success rate of venipuncture, the leakage rate of intravenous injection, residual radioactive dosage within the syringe and average exposure time of medical staff to radionuclide in the two groups of patients. ResultsThe one-time success rate of venipuncture in observation group was similar to that in the control group (P > 0.05). During the injection, no leakage was found in observation group, while 4 leakage in 37 patients underwent bone imaging and 3 leakage in 23 patients underwent kidney dynamic imaging in the control group were found; there was no significant difference between the two groups (P > 0.05). The residual radioactive dosage within the syringe in observation group was lower than that in the control group, and the exposure time of medical staff to radionuclide in observation group was also lower than that in the control group (P < 0.01). ConclusionsIntravenous indwelling needle for venous puncture can avoid leakage of radioactive imaging agent, reduce the residual radiological dosage within the syrings, increase the one-time puncture success rate and imaging resolution of dynamic scan, and improve the diagnostic accuracy and work efficiency effectively. Besides, the intravenous indwelling needle technique can reduce average exposure time of medical staff to radionuclide, acheaving the goal of optimized protection.
OBJECTIVE To investigate the mechanism of electrothrombosis by copper needle, in order to supply the referential data for clinical treatment of vessel deformity. METHODS The mechanism and condition of thrombus formation by copper needle were studied in vivo and in vitro using electrophysics, atom absorption spectrophtometry, histological, and histochemical methods. RESULTS Great deal of copper ion was dissociated, and agglutination of red blood cells(RBC) in blood could be observed in vitro after the current applied by copper needles. Formation of stable thrombus was related to voltage and time of application of electric current. CONCLUSION Dissociation of copper ion and agglutination of RBC are the basic principle of electrothrombosis with copper needle. A 4V direct current and 17.5 minutes are the safe and effective conditions for thrombus formation in the blood vessels.
Peripheral pulmonary lesions (PPLs) are generally considered as lesions in the peripheral one-third of the lung. A computed tompgraphy (CT) guided transthoracic needle aspiration/biopsy or transbronchial approach using a bronchoscope has been the most generally accepted methods. Navigation technique can effectively improve the diagnosis rate of peripheral pulmonary lesions, reduce the incidence of complications, shorten the time of diagnosis, and make the patients get timely and effective treatment.
Objective To explore the effect of community-hospital continuous nursing on the satisfaction of day surgery patients in terms of their nursing needs. Methods Sixty patients hospitalized in the day surgery ward in our hospital from April 2014 to March 2015 were enrolled in this study. According to the order of admission, they were divided into control group and observation group with 30 patients in each. Patients in the control group were given health guidance, while those in the observation group were given continuous nursing. Questionnaire survey was conducted in both the two groups. The nursing needs of patients after surgery were summarized, and the satisfaction of patients’ nursing needs through different nursing methods were analyzed. Quality of life questionnaire-C30 was used to evaluate the quality of life of the two groups of patients one month and three months after surgery, and the incidence of postoperative complications of the two groups was statistically analyzed. The changes of daily life ability of patients one month and three months after surgery were evaluated by the modified PAP index. Results Day surgery patients had a high demand for postoperative incision care, dressing change, postoperative medication, dietary guidance, postoperative guidance, health education and other aspects of health care needs. There was little demand for oral pipeline care and physical therapy. The satisfaction rate of patients in the observation group toward n ursing service (96.7%) was significantly higher than that in the control group (66.7%) (P < 0.05). The incidence of postoperative wound bleeding, poor healing, infection, urinary retention and other complications in the observation group was lower than those in the control group, but only the difference in the incidence of infection was statistically significant (P < 0.05). One month and three months after surgery, the quality of life in the observation group was significantly better than that in the control group (P < 0.05). The complete self-care ratio in the observation group was higher than that in the control group, and the proportion of slight defect in the observation group was lower than that of the control group (P < 0.05). Conclusion Continuous community-hospital nursing can improve the satisfaction of patients toward nursing service, promote patients’ quality of life, and facilitate patients’ recovery after surgery.

After expert consultation, 32 questionnaires were retrieved (a response rate of 91%), and all were valid (a validity rate of 100%). Through discussions at the expert consensus meeting, 17 policy suggestions were ultimately formed. ConclusionIt is recommended that the National Health Commission, in collaboration with the National Medical Products Administration and the customs, conduct in-depth discussions and refine the specific implementation measures for the temporary import of urgently needed clinical drugs to guarantee the safety, efficacy, and timeliness of clinical drug use.
Objective To observe the efficacy and safety of subretinal injection of Aflibercept for the treatment of refractory or recurrent polypoidal choroidal vasculopathy (PCV). MethodsA prospective clinical research. From January to June 2022, 18 patients of 18 eyes with PCV diagnosed in The Affiliated Eye Hospital of Nanchang University were included in the study. All patients underwent best corrected visual acuity (BCVA), indocyanine green angiography and optical coherence tomography (OCT). The BCVA examination was performed using the international standard visual acuity chart, which was converted to logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. The large choroidal vessel thickness (LVCT), central retinal thickness (CRT), sub-foveal choroidal thickness (SFCT) and retinal pigment epithelium detachment (PED) height were measured by enhanced depth imaging technique of OCT. The choroidal vascular index (CVI) was calculated. There were 18 patients of 18 eyes, 11 males of 11 eyes and 7 females of 7 eyes. The age was (64.22±3.86) years old. The disease duration was (5.22±1.80) years. The patient had received intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs for (7.72±1.36) times. The logMAR BCVA of the affected eyes was 1.28±0.25. The SFCT, CRT, LVCT, PED height were (436.56±9.80), (432.44±44.29), (283.78±27.10), (342.44±50.18) μm, respectively, and CVI was 0.65±0.01. All eyes were treated with a single subretinal injection of 40 mg/ml Aflibercept 0.05 ml (including Aflibercept 2.0 mg). According to the results of OCT and BCVA after treatment, the lesions were divided into active type and static type. The active lesions were treated with intravitreal injection of Aflibercept at the same dose as before. Quiescent lesions were followed up. Examinations were performed 1-3, 6, 9 and 12 months after treatment using the same equipment and methods before treatment. The BCVA, LVCT, CRT, SFCT, PED height, CVI, interretinal or subretinal fluid, lesion regression rate, injection times, and complications during and after treatment were observed. The BCVA, SFCT, CRT, LVCT, PED height and CVI before and after treatment were compared by repeated measures analysis of variance. ResultsEighteen eyes received subretinal and/or intravitreal injection of Aflibercept (1.61±0.85) times (1-4 times). At the last follow-up, the polypoid lesions regressed in 4 eyes and PED disappeared in 1 eye. Compared with before treatment, BCVA (F=50.298) gradually increased, CRT (F=25.220), PED height (F=144.16), SFCT (F=69.77), LVCT (F=136.69), CVI (F=72.70) gradually decreased after treatment. The differences were statistically significant (P＜0.001). Macular hole occurred in 1 eye after treatment, and the hole closed spontaneously 3 months after treatment. No serious complications such as retinal tear, retinal detachment, endophthalmitis and vitreous hemorrhage occurred during and after treatment. ConclusionSubretinal injection of Aflibercept is safe and effective in the treatment of refractory PCV.
Objective To determine the effectiveness of percutaneous catheter drainage (PCD) and to compare PCD with percutaneous needle aspiration (PNA) in the management of bacterial liver abscess. Methods The medical records of 206 patients with bacterial liver abscess admitted to this hospital between January 1989 and December 2009 were analyzed retrospectively. The outcomes of 96 patients receiving percutaneous treatment including PCD (PCD group, n=56) and PNA (PNA group, n=40) were compared, including the length of hospital stay, rates of procedure-related complications, treatment success, and death. Results There was no statistical difference in patients’ demographics or abscess characteristics between two groups (Pgt;0.05). The morbidity, mortality, and length of hospital stay in the PCD group and the PNA group were 1.79% vs 2.50%， 1.79% vs 2.50%， and (19.2±13.1) d vs (20.2±12.9) d, respectively, and the P values were 1.000, 1.000, and 0.887, respectively. There was statistically significant difference in successful rate between two groups （96.43% vs 75.00%， P=0.002）, but all simple abscesses with diameter of 5 cm or less were successfully managed in both PNA group and PCD group （13/13 vs 16/17， P=1.000）. Conclusions PCD is more effective than PNA in the management of bacterial liver abscess. PNA can be used as a valid alternative for simple abscesses with 5 cm in diameter or smaller.
ObjectiveTo investigate the clinical value of fine needle aspiration cytology (FNAC) combined with washout fluid detection of parathyroid hormone (PTH) in identifying parathyroid glands during thyroid cancer radical thyroidectomy. MethodsA total of 108 patients who underwent thyroid cancer radical thyroidectomy in Rizhao Central Hospital from June 2020 to December 2022 were selected as the study subjects. During the surgery, highly suspected parathyroid tissues were punctured with fine needle aspiration. FNAC and washout fluid were collected for PTH detection. Using the results of postoperative histopathological examination as the gold standard, the accuracy of different methods in identifying parathyroid glands during surgery was analyzed. ResultsAmong the 73 positive cases, the PTH level in the washout fluid was (591.20±84.30) pg/mL, while in the 35 negative cases, it was (18.69±2.53) pg/mL. The PTH level was significantly higher in the positive cases compared to the negative cases (P＜0.05). Postoperative routine histopathological examination confirmed parathyroid tissues in 91 cases, while in 17 cases, they were confirmed as adipose tissues (11 cases) or lymphoid tissues (6 cases). In the 17 cases confirmed as non-parathyroid tissues, both two methods considered them as non-parathyroid tissues. The sensitivity of puncture eluent in detecting PTH was 80.22% (73/91), that of cytological smear was 70.33% (64/91), and that of puncture eluent combined with cytological smear was 94.50% (86/91). There was no significant difference between the sensitivity of puncture cytology smear and puncture eluent in detecting PTH (P＞0.05). The sensitivity of combined detection of the two methods was higher than that of individual detection, and the difference was statistically significant (P<0.05). ConclusionThe combined detection of PTH by fine needle puncture smear and eluent can improve the accuracy of identification of parathyroid gland during radical thyroidectomy, and is beneficial to the identification and protection of parathyroid gland during surgery.
