A controversy still exists in the management of nerve injection injury. The results of different timing of operation and methods in treating this type of nerve injury were analysed in limb s function, neuroelectrophysiology and histology. The results showed that the recovery of the injuried nerve in the group of operation, was considerably better than that in the group without operation. In the group of operation early incision of the epineurium with saline irrigation! was superior to late neurolysis. It was suggested that the early incision with saline irrigation could be used as an emergency management for this type of nerve injury.
To evaluate an improved treatment of an autologous fat injection for hemifacial atrophy to increase the survival rate of the fat graft and decrease complications including colliquation, necrosis, and absorption of the graft fat. Methods From March 1999 to October 2004, 31 patients with hemifacial atrophy underwent an improved treatment by an autologous fat injection for their diseases. There were 12 males and 19 females aged 1928 years (average, 23.5 years). The patients were divided into the following 3 groups according to the atrophy extent: the mild group (n=9), the moderate group (n=19), and the severe group (n=3). Based on the previous researches on the fat transplantation techniques, the improved treatment combined the following strategies that were simply called “3L3M”: low position for the fat donation, low pressure for the fat harvesting, and lowspeed centrifugation for purification of the fat; multipoint, multitunnel, and multiplane for injections of the fat graft. The preoperative and the postoperative photos were taken and the findings were compared to make clear whether the hard and firm masses and cysts existed; then, the decision was made about whether the patients needed another operation according to whether the patients had a natural facial expression and whether the patients had comfortable feelings as well as the ray findings. Results All the patients had a satisfactory symmetrical face after 1 injection of the fat in 15 patients, 2 injections in 13 patients, and 3 injections in 3 patients. The effect of the 3rd injection was better than that of the 2nd injection; the effect of the 2nd injection was better than that of the 1st injection; the fat volume for the injection could be gradually decreased. The fat volumes for injections were as follows: 814 ml (average, 11 ml) in the submaxillary region, 1525 ml (average, 20 ml) in the buccal region, 510 ml (average, 75 ml) in the zygomatic region, and 1820 ml (average, 19 ml) in the forehead region. The followup for 35 years revealed that there wasno infection, hard and firm mass, cyst or other complications. The pigmentationin the affected face was significantly improved. Conclusion Compared with the traditional treatments, the improved treatment of an autologousfat injection for hemifacial atrophy can achieve a satisfactory symmetry of theface with no injury to the donor site or complications in the recipient site. This improved method is an ideal treatment for hemifacial atrophy.
OBJECTIVE To investigate the effects of intra-articular injection of sodium hyaluronate in post-operation treatment of the knee. METHODS From January 1998 to February 2001, 4 ml of sodium hyaluronate injection was injected into the knee joint of the 134 cases at the end of arthroscope operation, or the 91 cases undergoing open operation of the knee at the time when the drain tube was removed (treatment group). Five days after operation, the hydrarthrosis was removed and 2 ml of sodium hyaluronate was injected into the knee joint. According to the patient’s condition, injection of sodium hyaluronate was performed once a week for several weeks. Clinical evaluation was made by evaluating pain visual analog scale (VAS) and painless range of movement (ROM) of the joint at every definite point of time. The 85 patients in control group used nothing at the same time. RESULTS The VAS score of patients in the treatment group was significant lower than that of the control group. The period to the maximal painless ROM of the joint was 6 days in the treatment group after open operation, while 9 days in the control group. CONCLUSION Sodium hyaluronate appears effective in relieving post-operation pain of the knee joint.
ObjectiveTo systematically evaluate the efficacy of different interventions in preventing rocuroniuminduced injection pain or withdrawal movements, so as to provide references for preventing adverse reactions induced by rocuronium injection in clinical practice. MethodsWe electronically searched PubMed, EMbase, The Cochrane Library (Issue 3, 2014), CBM, and CNKI databases to collect randomized controlled trials (RCTs) about the prevention of rocuronium-induced injection pain or withdrawal movements from inception to March 2014. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.2.8 software. ResultsA total of 43 RCTs involving 6 034 patients were include. The results of meta-analysis showed that compared with the placebo/blank group, lidocaine pretreatment with venous occlusion (RR=0.37, 95%CI 0.29 to 0.48, P<0.000 01), opioid drug pretreatment with venous occlusion (RR=0.77, 95%CI 0.68 to 0.87, P<0.000 1), lidocaine pretreatment with venous injection (RR=0.51, 95%CI 0.44 to 0.59, P<0.000 01), opioid drug pretreatment with venous injection (OR=0.03, 95%CI 0.02 to 0.05, P<0.000 01), ketamine pretreatment with venous injection (RR=0.36, 95%CI 0.23 to 0.54, P<0.000 01), mixing sodium bicarbonate (NaHCO3) with rocuronium (OR=0.02, 95%CI 0.01 to 0.04, P<0.000 01) and local heating (RR=0.74, 95%CI 0.63 to 0.88, P=0.000 6) were all effective in decreasing the incidence of rocuronium-induced injection pain or withdrawal movements. ConclusionThe intravenous injection of opioid drugs was effective in preventing rocuronium-induced injection pain or withdrawal movements, while local heating needs further research. Due to the limited quantity and quality of the induced studies, the above conclusion still needs to be verified by more high quality studies.
Objective To assess the effect of Dengzhanhua Injection for angina pectoris. Methods We performed an electronic search for MEDLINE (1966 to 2004), EMBASE (1974 to 2004), The Cochrane Library (Issue 4, 2004), CBM and CNKI (1980 to 2004). We included randomized controlled trials that met the inclusion and exclusion criteria and evaluated the quality of those trials and performed the meta-analysis by RevMan 4.2.7. Results Eight trials were included involving 634 patients. However, they were of poor quality. The results of meta-analysis indicated that there were statistical difference on symptoms and electrocardiogram (ECG) improvements between Dengzhanhua and control group (Breviscarpine≥30 mg) with RR 1.26, 95%CI 1.11 to 1.44 and RR 1.30, 95%CI 1.14 to 1.49, respectively. However, Dengzhanhua Injection (Breviscarpinelt;30 mg) vs. basic therapy showed no statistical difference in either symptom improvement (RR 1.03, 95%CI was 0.90 to 1.18) or ECG improvement (RR 1.01, 95%CI 0.86 to 1.20). In addition, Dengzhanhua decreased the myocardial infarction attacks in one year following up (OR 0.06, 95%CI 0.01 to 0.29). Conclusions Little evidence shows that Dengzhanhua is superior to simple basic therapy in the symptoms and ECG improvements as an auxiliary drug. However, this systematic review can not draw a conclusion about the effectiveness of Dengzhanhua Injection compared to simple basic therapy in the treatment of angina pectoris due to the poor quantity of included trials.

【Abstract】ObjectiveTo investigate the efficacy of radiofrequency (RF) ablation comparing with percutaneous ethanol injection (PEI) in the treatment of postoperative recurrent hepatocellular carcinoma. MethodsOne hundred and thirtyseven patients with recurrent hepatocellular carcinoma excluding those with extrahepatic metastasis or Child C liver function were analyzed retrospectively. Of these patients, 74 cases with 86 lesions underwent RF therapy, while the other 63 cases with 75 lesions treated with PEI therapy. In RF group, the average size of lesions was 2.05 cm in diameter including 9 lesions were more than 3 cm in diameter (the maximum size of the lesions was 4 cm in diameter). In PEI group, all lesions were less than 3 cm in diameter, averagely 2.03 cm. Blood routine, liver function, AFP level and Doppler ultrasound were observed before and after therapy 1-year, 2-year, 3-year survival rates were calculated in two groups as well. Results①There was no serious complications in two groups. ②Complete tumor necrosis was 93.0%(80/86) in RF group and 81.3%(61/75) in PEI group. In RF group, complete tumor necrosis rate for lesions less than 3 cm in diameter was 96.1%(74/77), while that was only 66.7%(6/9) for lesions greater than 3 cm in diameter. ③The 1-year, 2-year, 3-year survival rates were 74.3%(55/74), 62.2%(46/74) and 54.8% (17/31) in RF group as well as 68.3%(43/63), 57.1%(36/63) and 45.0%(9/20) in PEI group， respectively. ④The average treatment needed to achieve tumor ablation were 1.3 for RF group, and 2.5 for PEI group，respectively. ConclusionRF is an efficient treatment for recurrent hepatocellular carcinoma.
