OBJECTIVETo explore clinical efficacy and key matters for the treatment of femoral intertrochanteric fracture and integrity of lateral trochanteric wall by proximal frmoral nail antirotation (PFNA).

METHODSFrom June 2010 to December 2012,210 femoral intertrochanteric fracture patients treated with PFNA were retrospectively analyzed, including 76 males and 134 females aged from 46 to 96 years old with an average of 71 years old. All fracture were caused by injury and classified to type I (5 cases) type II (16 cases), type III (73 cases) and type IV (116 cases) according to Evans classification. The time of getting out of bed, postoperative complications and displacement of screw blade and fracture healing were observed, Baumgaertner criteria were used to evaluate quality of fracture reduction, Harris criteria were used to evaulate hip joint function.

RESULTSAll incisions were healed at stage I, no complications occurred except incomplete of lateral trochanteric wall patients without reconstruction, other patients could get out of bed with crutches at one week and all patients discharged from hospital at 10 days after operation. One hundred and seventy-eight patients were followed up from 3 to 17 months with an average of 10 months. One case occurred unhealed fracture displacement caused by screw blade cutting, 2 cases occurred screw blade transfomed to proximal and out femoral head, other patients obtained fracture healing at 12 to 16 weeks after operation. According to Baumgaertner criteria, 130 cases obtained good results, 45 cases acceptable, and 3 poor; while 107 cases obtained excellent results, 65 good, 3 good and 3 poor according to Harris score.

CONCLUSIONPFNA with mechanical advantage of intramedullary fixation has advantsges of stable fixation, shorter operation time, minimally invasive. Satisfied clinical effects could obtained by grasping fixation principle, dealing with negative factors in operation. Intraoperative reconstruction for integrity of lateral trochanteric wall could assure stable fixation and earlier get out of bed.

Objective To evaluate the relationship between combined muhigene detection and response to chemotherapy and prognosis in epithelial ovarian carcinomas(EOCS).Methods A total of 80 ovarian tissue samples taken from the surgical specimens of patients with EOCS of our hospital in the last two decades who had received chemotherapy "after surgery were paraffin-embedded.The samples were divided into 2 groups,good prognosis group(patients who survived more than 2 years,n=46)and poor prognosis group(patients who survived less than 2 years,n=34).The expression levels of ToPo-Ⅱ,Ki-67,MGMT, PCNA,p27,p53,pl6,P-gp,LRP,GST-?,bcl-2,C-myc,Fas,bax,MSH2,MRP and BCRP were investigated by the combination of tissue arrays and immunohistoehemical streptavidin-biotin peroxidase(SP) method in all samples.Data were analysed with SPSS 12.0 for windows.Results There were statistically significant differences in the positive expression levels of P-gp,BCRP,MGMT,MSH2,p27 and p16(62%, 50% and 50% in poor prognosis group vs 33%,28% and 28% respectively,P

Objective To investigate the changes of serum glycocholicacid(CG),hyaluronic acid(HA),procollagen type Ⅲ(PCⅢ) in neonatal diseases.Method The levels of serum CG,HA and PCⅢ were measured by radioimmunoassay in 46 neonates with different diseases and 20 healthy neonates.Results Serum CG and HA in patients group were significant higher than those in healthy control group(P

Objective To observe the time-dependent changes of astrocytes and microvessels in the ischemic core and surrounding areas.Methods Glial fibrillary acidic protein (GFAP)was measured by HE,and CD31 by immunohistochemistry as markers in post-mortem specimens from ten patients,who died of cerebral infarction.Results Each section of the infarcted brains was divided into four areas (the area 0-3).GFAP expressed a little in area 0 and 1,increased in a time-dependent manner in area 2 and 3;CD31 die not expressed in area 0,expressed a little in the area 1,and increased in area 2 and 3 continuously.Conclusions The proliferation of astrocytes and microvessels may play a significant role in the process of restoration after cerebral infarction.

OBJECTIVETo improve the diagnosis and treatment of testicular teratoma in children by analysis of clinical data.

METHODSWe retrospectively analyzed the clinical data about 64 cases of testicular teratoma treated in the Children's Hospital of Chongqing Medical University from 1995 to 2014.

RESULTSSixty-one of the cases presented painless scrotal mass with a sense of bearing down and the other 3 cases were confirmed because of empty scrotum diagnosed as cryptorchidism. The level of serum alpha fetal protein ( AFP) was obviously increased in 46 cases but normal in the other 18 preoperatively. Ultrasonography manifested abnormal inhomogeneous echo zones with calcification or necrosis. X-ray examination presented patchy or curvilinear high-density shadows in 28 cases. Forty-one of the patients underwent testis-sparing surgery (TSS) , 20 received high inguinal orchiectomy, and 3 refused surgical treatment. Pathological examination revealed 3 mature germinal layers in the 49 cases of mature teratoma and immature germinal tissue, including the original neural tube, and 11 cases of immature teratoma. The mature cases were exempted from chemotherapy, while the immature cases received the combination of cisplatin, etoposide, and bleomycin (PEB). The patients were followed up for 2 years postoperatively, which revealed no recurrence or metastasis.

CONCLUSIONMost children with testicular teratoma presented painless scrotal mass with a sense of bearing down and with abnormal serum AFP in most cases. Ultrasonography and plain radiography of the scrotum contribute to the diagnosis of the tumor. TSS is the main treatment option and intraoperative frozen-section can help the surgeons decide on the surgical mode. Postoperative chemotherapy is necessitated for immature teratoma but not for mature cases.

OBJECTIVETo study the enriching method of total flavonoid from Herba Leonuri with polyamide and macroporous resin.

METHODSeven enriching and purifying methods were compared with the yield and purity as indexes. The method of enriching with polyamide and macroporous resin was confirmed and the process of purifying was determined by orthogonal design.

RESULTD101 resin is packed by wet method, the ratio of diameter to height is 1:7. After mixed with the extract liquids, the weight of wet resin increased to 3 times of the dry resin. Evaporated the wet resin to dryness, mixed well with a little of 95% ethanol and dry polyamide powder, evaporated them to dryness again. Elute with deionized water until the effluent being colourless, then loaded it on the macroporous adsorptive resin, elute with 50% ethanol, the volume of effluents was collected to 7 times of the column volume. The purity of total flavonoids reached to 23%, while the diversion rate from raw Herba Leonuri was to 69%.

CONCLUSIONThe process is simple and convenient, and the regeneration of resin is easy, which has a good application foreground.

OBJECTIVETo explore the prevalence of chronic obstructive pulmonary disease (COPD) and its risk factors in rural area in the southern part of Hubei province and to provide evidence for prevention and treatment.

METHODSUsing uniform scheme, procedures and questionnaire, a multistage survey for 1883 people in rural area in southern part of Hubei province was performed, and physical examinations and lung function tests were conducted for every participant.

RESULTSIn this survey, 186 COPD cases were identified with a overall prevalence of 9.88%. The prevalence for male was 13.68% while in female it was 6.46%. The prevalence was higher in males than in females (chi2 = 27.48, P< 0.001) and higher with the increase of age (chi2 = 79.22, P<0.001). Factors associated with COPD were identified in one-way variance model as follows: sex, age, smoking, time for cooking, using biomass fuels for in-door cooking, family history, frequent cough before age 14, low body index and having house remodelling in the last five years. Results from multivariate logistic regression analysis showed that sex (OR= 1.3010), age (OR = 1.8506), smoking (OR= 3.0118), cooking time (OR= 1.7651), family history (OR = 1.5278), frequent cough before age 14 (OR = 2.8965) were risk factors.

CONCLUSIONThe prevalence of COPD in the southern part of Hubei province was high, suggesting that comprehensive intervention measures should be taken.
