The applied anatomy and clinical application were described in this paper. The blood supply of this flap was based on the second dorsal metacarpal artery. It gave some advantages of as easy of application, safe and reliable. Since November 1990, we had successfully used six such flaps in covering the soft tissue defects of the hand.

It is difficult to repair the pulp defect of finger with good function. Here reported two cases of pulp defect of the thumb which were repaired with free palmris brevis musculo-cutaneous flap. The flap was designed as the following: taken the line crossing the pisiform and metacarpo-phalangeal joint of the little finger as the longitudinal axis of the flap. The proximal end of the flap was at the level of pisiform and the distal end was the distal transverse palmar crease. The radial border was the radial side of the palmris brevis and ulnar border was the ulnar edge of the palm. The flap should not be larger than 6.5 cm x 2.5 cm. The flap was dissected with proper ulnar vessels and the accompanying arterial branch and superficial branch of the ulnar nerve. The flap was transferred to repair the pulp defect of the thumb. The vessels were anastomosed with the radial artery and cephalic vein at the snuffbox. The nerves were sutured to the digital nerve. Three months after operation, the defect was healed and the sensation of pulp was recovered. The donor area was painless and without sensation disturbance. The motion of the little finger was normal. The function of the thumb was restored. It was concluded that the palmaris brevis musculocutaneous flap is one of the best donor region to repair pulp defect of thumb.
目的:了解正常妊娠妇女血清中常用肝功能指标测定结果及变化。方法:分别在早孕（孕10～14周）、中孕（孕20～24周）、晚孕（孕30～34周）及产后（产后12周）四个时期序贯性测定120例正常妊娠妇女血清谷丙转氨酶（ALT）、谷草转氨酶（AST）、γ谷氨酰转移酶（GGT）、乳酸脱氢酶（LDH）、总胆红素（TBIL）、直接胆红素（DBIL）、总蛋白（TP）、白蛋白（ALB）、前白蛋白（PA）的水平并进行比较。结果:ALT、AST在早、中、晚孕及产后各期相对于正常对照均升高（P＜0.01）；TBIL和DBIL在早、中、晚孕均降低（P＜0.01）；TP、ALB随孕期增加逐渐下降,产后回升,到产后12周上升到正常水平（早、中、晚孕P＜0.01,产后P＞0.05）；GGT在孕期中逐渐升高,于晚孕期达最高峰（P＜0.01）,产后稍有下降；LDH在孕早中期无明显变化（P＞0.05）,孕晚期上升,到产后12周仍呈一上升趋势（P＜0.01）；PA在孕早期低于正常对照（P＜0.01）,后随孕期上升,到中孕期后上升到正常（P＞0.05）。结论:本次实验观察到在妊娠期肝功指标ALT、AST、GGT、LDH升高,可能因为孕妇肝脏负荷增加、基础代谢和能量消耗增多、甾体激素水平增高引起。胆红素代谢指标及营养性指标TBIL、DBIL、TP、ALB、PA降低,可能是妊娠期血浆稀释引起。临床诊断妊娠合并肝功能损害时应考虑上述变化。
Objective To report the clinical characteristics and treatment analysis of 3 cases of congenital ulnar collateral flexor contracture of the forearm and take a reference for clinic. Methods A total of 3 patients with congenital ulnar collateral flexor contracture of the forearm were admitted between February 2019 and August 2021. Two patients were male and 1 was female, and their ages were 16, 20, and 16 years, respectively. The disease durations were 8, 20, and 15 years, respectively. They all presented with flexion deformity of the proximal and distal interphalangeal joints of the middle, ring, and little fingers in the neutral or extended wrist position, and the deformity worsened in the extended wrist position. The total action motion (TAM) scores of 3 patients were 1 and the gradings were poor. The Carroll’s hand function evaluation scores were 48, 55, and 57, and the grip strength indexes were 72.8, 78.4, and 30.5. Preoperative CT of case 2 showed a bony protrusion of the flexor digitorum profundus tendon at the proximal end of the ulna; and MRI of case 3 showed that the ulnar flexor digitorum profundus presented as a uniform cord. After diagnosis, all patients were treated with operation to release the denatured tendon, and functional exercise was started early after operation. Results The incisions of 3 patients healed by first intention. Three patients were followed up for 12, 35, and 12 months, respectively. The hand function and the movement range of the joints significantly improved, but the grip strength did not significantly improve. At last follow-up, TAM scores were 3, 4, and 4, respectively, among which 2 cases were excellent and 1 case was good. Carroll’s hand function evaluation scores were 95, 90, and 94, and the grip strength indexes were 73.5, 81.3, and 34.2, respectively. ConclusionCongenital ulnar collateral flexor contracture is a rare clinical disease that should be distinguished from ischemic muscle contracture. The location of the contracture should be identified and appropriate surgical timing should be selected for surgical release. Active postoperative rehabilitation and functional exercise can achieve good hand function.
Five fresh human forearms removed from cadavers were used to study the vascular concentration of the flexor digital tendons by stereology method. The results showed: (1) The Vv is 0.45%, and Lv is 1.9; (2) The vascular concentration of the flexor digital tendons of different fingers showed no significance statistically; (3) The vascular concentration of the tendons within the digital sheath was less than that outside the digital sheath (plt;0.01); (4) The vascular concentration of the tendons were decreasing gradually form the thum dto litter finger.
Through dissection of 12 fresh finger specimens, the anatomy of the distal part of dorsal aponeurosis and its function was closely observed. A direct reparative procedure of the terminal tendon by using tendon flap graft was deseribed for the treatment of chronic mallet finger deformity. Correction of deformity, restoration of active motion of DIP and avoidance of residual pain were observed in three clinical cases.
Objective To determine the usefulness of serial measurements of the rapid shallow breathing index ( f/VT , RSBI) as a predictor for successfully weaning of patients undergoing prolonged mechanical ventilation ( gt; 72 hours) . Methods 76 mechanically ventilated patients were prospectively analyzed. 120-min spontaneous breathing trial was conducted after the patients having fullfiled the traditional weaning criteria, and RSBI were continuously monitored by the ventilator at five time points ( 5, 15, 30,60, and 120 min) . A repeated measure of general linear model in SPSS 15.0 was conducted to analyze the data. Results 62 patients completed 120-minute spontaneous breath trial and in which 20 patients failed weaning. There was no significant difference of RSBI at five time points during weaning ( P gt;0. 05) . But thevariation trends of RSBI during weaning time were significant different between the successful weaning patients and the failed weaning patients ( P lt; 0. 05) . Conclusions In patients undergoing prolonged mechanical ventilation, the variation trend of RSBI is more valuable than single RSBI in the prediction ofsuccessful weaning.
