BACKGROUND:Canada Montreal Scholar Mutch et al have recently proposed a new morphologic classification of fracture of greater tuberosity of humerus. They divided these fractures into three typeavulsion, split and depression.
OBJECTIVE:To compare the recovery of shoulder function after conventional plate-screw and hol ow-screw fixation for the repair of the split fracture of greater tuberosity of humerus.
METHODPatients with greater tuberosity of humerus, who were treated in the Department of Orthopedics of Yichang Yiling Hospital, China from January 2010 to January 2014, were classified according to Mutch’s classification. A total of 83 patients with split greater tuberosity of humerus after complete fol ow-up were retrospectively analyzed. Of them, 23 cases received plate-screw fixation as plate-screw group, and 60 cases received hol ow-screw fixation as hol ow-screw group. Visual Analog Scale, the United States Scores of Shoulder and Elbow Surgeons, and Constant and Murley Scoring Systems were utilized to assess the therapeutic outcomes. Patient’s pain and changes in shoulder function were analyzed before and after treatment.
RESULTS AND CONCLUSION:A total of 83 patients were fol owed up. Fixator was obtained at 1 year after surgery in al patients. No significant difference in Visual Analog Scale, the United States Scores of Shoulder and Elbow Surgeons, and Constant and Murley Scoring Systems was detected in both groups before treatment (P>0.05). Significant differences in Visual Analog Scale, the United States Scores of Shoulder and Elbow Surgeons, and Constant and Murley Scoring Systems were detectable in both groups at 16 months after removal of the fixator (P<0.05). Data were better in the hol ow-screw group than in the plate-screw group. Above results suggested that hol ow-screw fixation in the repair of split fracture of greater tuberosite of humerus is simple to be operated, with smal trauma, and is an ideal fixation method. Clinical repair effect is better than plate-screw fixation.

BACKGROUND:A single hemostatic material has been proved not to facilitate wound healing or to produce certain adverse reactions; while composites composed of two or three different materials can improve the
advantage and histocompatibility of hemostatic materials.
OBJECTIVE:To investigate the effect of gelatin sponge impregnated with hemocoagulase solution on amount of bleeding in patients with lumbar fractures undergoing posterior spinal decompression.
METHODS: Fifty patients with lumbar fractures who were scheduled for open reduction, pedicle screw fixation
and laminectomy were enroled, including 25 cases treated with gelatin sponge impregnated with hemocoagulase before surgical incision closure as test group and 25 cases treated with single gelatin sponge before surgical
incision closure as control group. Postoperative drainage volume, drainage time, length of stay, number of re-admissions and postoperative complications were compared between the two groups.
RESULTS AND CONCLUSION:The postoperative drainage volume, drainage time and length of stay in the test group were significantly less than those in the control group (P < 0.000 1). No infection, epidural hematoma, or
re-admission of patients was found, and there was no hemocoagulase-impregnated absorbable gelatin sponge- related adverse reaction. These findings indicate that posterior laminectomy with hemocoagulase-impregnated gelatin sponge can significantly reduce patients’ postoperative wound drainage and shorten the length of stay.

OBJECTIVE:To improve the HPLC-fluorometric method in the determination of telmisartan in human plasma.METHODS:Using naproxen as internal standard,the plasma was extracted with ethyl acetate.The separation was performed on Symmetry C8 with mobile phase consisted of acetonitrile -0.01mol?L-1 potassium dihydrogen phosphate buffer solution(47∶53) at a flow rate of 1.0ml?min-1.The ?Ex was set at 305nm and the ?Em was set at 365nm,and the sample size was 20?L.RESULTS:The linear range of telmisartan was 2.5～200ng?mL-1(r=0.999 8),with the lowest detectable limit at 1ng?mL-1.The average recovery of extraction was (89.91?10.07)%.Both the intra-day RSD and inter-day RSD were less than 10%.The sample showed a good stability within 24 hours after three freeze-thaw cycles and extractions.CONCLUSI-ON:The method is simple,sensitive,accurate and reproducible,and suitable for the determination and pharmacokinetic study of telmisartan in human plasma.

Objective To analyze the dynamic flow of pediatricians from 2010 to 2015, their present deployment and workload as compared with physicians across the country, in order to provide reference for their effective allocation.Methods Selecting data indexes from Chinese Statistical Yearbook and China Health and Family Planning Yearbook, and using Excel for statistics of relevant index data.By means of horizontal and vertical comparisons, a dynamic analysis was made on such indexes as the number of pediatricians, that of pediatricians per thousand children, and the number of hospital admissions and the number of hospitalizations per pediatrician.Results The total of pediatricians only increased by 2.32% from 2010 to 2015.On the other hand, the number of pediatricians per thousand population only accounted for 23.42% of physicians per thousand population in 2015.These five years witnessed a 40.58% workload increase of outpatient/emergency visits per pediatrician, and 36.70% increase of discharged inpatients.Conclusions China is faced with the challenges of shortage and insufficient supply of pediatricians, worsened by excessive workloads.It is advisable to improve pediatrician development pattern, raise their remuneration, and ease their workload, for the sake of better healthcare for children.

EAC cell line grew rapidly,steadily, and it had similar microscopic morphology to adenocarcinoma cell. Chromosome analysis reveal EAC chromosome counts ranging in hyperdiploid. The expression of ER, PR, P53, MDM2 were negative by SP immunohistochemistry. Tumorigenicity of EAC in nude mice was 100%. CONCLUSION: A new human endometrial carcinoma, EAC, is established successfully, which is helpful for the basic and clinical study of endometrial carcinoma.

Objective To summarize the clinical experience of combined liver and kidney transplantation (CLKT). Methods CLKT was performed on 22 patients. The orthotopic liver transplantation (LT) was preceded with the classic fashion in 10 patients and piggyback fashion in 12 patients. The renal allograft was implanted to the iliac fossa routinely. After operation, the patients received an induction therapy with anti-CD25 monoclonal antibody or antithymocyte globulin ( ATG) and a maintenance therapy with tacrolimus (Tac), mycophenolate mofetil and prednisone. Results The CLKT was successfully performed on all 22 patients, and the graft function was restored well postoperation. During the perioperative period, an acute rejection episode of liver occurred in one patient and acute renal allograft rejection episode in 2 patients. The Tac toxicity occurred in one patient. The hemorrhage of digestive tract occurred in one recipient and the hemorrhage of peritoneal cavity in one patient. The pleural effusion occurred in 6 recipients. The pneumonia occurred in 2 cases and the peritoneal infection in one patient During a follow-up period of 6 months to 7 years 11 months, three patients died because of cytomegalovirus pneumonia in 2 patients and acute myocardial infarction in, one patient, The 1-, 3-, 5-year survival rate of recipients was 86,4 %, 81.3 %, 72.7 % respectively. Conclusion The CLKT is an effective method for treatment of patients with end-stage liver djsease and chronic renal failure.

The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.
