There are many causes of postpartum hemorrhage in lying-in women.The authors retrospectively analyzed the clinical data of 40 cases of uterine inertia-induced postpartum hemorrhage,investigated its causes,and proposed that for different cases midwives should take different preventive measures,such as psychological persuasion,childbirth guidance,anticipation,prediction,and pretreatment,so as to reduce the incidence of uterine inertia-induced postpartum hemorrhage.

ObjectiveTo observe the clinical effects of locking proximal humerus plate(LPHP) in the treatment of complex proximal humeral fracture of aged patients and to analyze the influencing factors. Methods Among 39 cases with complex humeral fractures (aged 60-83 years),there were 29 cases with three-part fractures and 10 with four-part fractures according to the Neer classification.They were operated by LPHP via deltoid-pectoral approach. Neer numerical rating system was employed to evaluate postoperative function of shoulders.Results39 cases were followed up for average of 16 months.According to Neer numerical rating system,the excellence rates of three-part fractures and four-part fractures were 86.2％ (25 cases) and 50.0％ (5 cases),respectively,with total excellence rate of 76.9％(30 cases). Age (OR =1.314, P＜0.05) and fracture type ( OR =1.295, P＜0.05)ofpatientswereindependentriskfactorsforprognosis of proximal humeral fracture of aged patients by multiple logistic regression. Conclusions LPHP is an effective implant for treating complex proximal humeral fracture of aged patients,with age and fracture types as important risk factors of prognosis.<英文关键词>=humeral fractures

Since the fecal bacteria transplantation (FMT) had been exist for a long time, it attracted more attention in recent years because this therapy could adjust the bacteria disturbance rapidly in clinical settings. Recent studies demonstrated that fecal microbiota transplantation (FMT) has great clinical value in the treatment of Clostridium difficile infection, inflammatory bowel disease, Intractable functional constipation and other diseases. But the FMT is not as perfect as we expect, so we did this article to review the history and terminology of FMT, and summarized the progress in nursing methods of FMT.

Objective According to principle of forming primer dimer,a new cloning gene method was established. Methods Two and more oligonucleotide with complementary partnership in the 3′ end were synthesized by artifical method,oligonucleotide,Taq DNA polymerase and dNTP were mixed in the proportion of reasonable,then expanded and extended by PCR,result was identifed by agarose gel electrophoresis.Results A clear special band was appeared in the agarose gel. Conclusion Short fragment target gene less than 500 bp may be synthesized by this method.

Objective To compare the clinical effect of arthroscopic single-row and suture-bridge double-row fixation of full-thickness rotator cuff tear.Methods A retrospective study was conducted on 40 patients with full-thickness rotator cuff tear treated by single-row and suture-bridge double-row fixation between May 2010 and May 2012.Single-row rotator cuff repair was performed in 18 patients and doublerow repair in 22 patients.The two techniques were compared in aspects of complications,recovery time to daily life,time to achieve satisfaction score,re-tear rate,pre-and post-operative VAS,University of California at Los Angeles Shoulder Scores (UCLA),and American Shoulder and Elbow Surgeons (ASES).Results Mean period of follow-up was 15.6 months (range,13-24 months).Both treatment were effective in improving VAS,UCLA,and ASES,but the differences were insignificant (P ＞ 0.05).Recovery time to daily life,time to achieve satisfaction score,and large rotator cuff re-tear rate were 69.2 ± 16.6)d,(196.4 ±24.6)d,and 4/5 respectively in single-row fixation,with significant differences from (54.1 ± 13.3)d,(165.0 ±20.6)d,and 1/8 in suture-bridge double-row fixation (P ＜0.05).Conclusion Both treatments are effective for rotator cuff reconstruction,but suture-bridge double-row fixation provides earlier recovery to daily life,shorter time to achieve satisfaction score,and lower incidence of large rotator cuff retear.

Objective: To observe the feasibility and clinical curative effect of anatomical reduction and fixation of lesser trochanter through posterior-lateral approach for the treatment of comminuted femoral intertrochanteric fractures in elderly patients. Methods: A total of 19 cases with comminuted femoral intertrochanteric fracture, aged 60 to 84 years were enrolled in this study.According to Evans-Jensen classification, 13 cases had type Ⅱ B and 6 cases had type Ⅲ femoral fracture.Through the posterior-lateral approach, the lesser trochanter was fully exposed, reduced and fixed by screw.The proximal and distal femur were well fixed with dynamic hip screw(DHS)or proximal femoral locking plate(PFLP). The lesser trochanter reduction was observed by intraoperative vision and postoperative X-ray.The function evaluation after hip surgery was performed by using Sanders hip function score. Results: All 19 patients obtained the anatomic reattachment in the lesser trochanter.All patients were followed up for an average of 18 months.After treatment, the Sanders hip function score were excellent in 7 patients(36.8%), fine in 12 cases(63.2%). And curative efficacy was good in all cases(100%). There was no significant difference in the curative effect between patients with different classification and gender. Conclusions Through the posterior-lateral approach, the surrounding structures of the lesser trochanter can be fully exposed, and the lesser trochanter can be anatomically repositioned.The posterior-lateral approach to anatomical reduction and fixation of lesser trochanter is an effective and feasible method for the treatment of comminuted intertrochanteric fracture in the elderly.
