Objective To retrospectively study revisions for infected total hip replacements in 30 cases and discuss the bacteriological characters of the infected total hip replacements,difficulties and strategies in the revision.Methods Thirty revisions of infected total hip replacements were reviewed retrospectively.There were 12 males and 18 females,with mean age of 62.5 years(31-86 years)at revi- sion surgery.Infection was presented one month to four years(mean seven months)after THA operation. The diseases for initial operation included femoral neck fractures in 12 cases,femoral head necrosis in 11,hip osteoarthritis in five and rheumatoid arthritis in two.Twelve eases were treated by one-stage revi- sion and 18 by two-stage revision.Results Before the revision operation,the hip infection were diag- nosed by bacterial culture in 18 cases including five with Staphylococcus epidermidis,four with Staphylo- coccus aureus and nine with other bacteria.Bacteria growth appeared on the specimens from 23 hip joints during the revision surgery but not on the specimens from seven hip joints.Of 12 one-stage revisions,10 cases were followed for mean 16 months,which showed infection recurrence in two eases.Of 18 two-stage revisions,13 cases were followed for mean 20 months,which showed one case with infection recurrence. The mean Harris hip score was improved from preoperative 44 to 84 at follow-up.Conclusions 1) The main bacteria in the infected hip are antibiotic resistant Staphylococcus.2)Because the revision op- eration is difficult,careful preparation before revision is important for success.The fresh surgeon should not attempt.3)The revision strategies should vary according to specific status of the cases.The infection recurrence rate is lower when using a two-stage revision strategy.4)Application of antibiotic bone cement can help improve treatment effect and facilitate functional recovery of the joints.5)The scientific rehabil- itation after operation is very important to functional recovery.

OBJECTIVETo study the correlation of polymorphisms of CYP1A1 MSPI and glutathiones S-transferase (GST-M1) independently and in combination with the risk of lung cancer.
METHODSA case control study which included 91 cases of lung cancer and 138 controls collected from the First Affiliated Hospital of Sun Yat-sen University of Medical Sciences, Guangzhou Tumor Hospital and The Red Cross Hospital of Guangzhou or conmunity area. All subjects were investigated with a uniform questionnaire. Blood samples were collected from all cases and controls for detecting CYP1A1 MSPI and GST-M1 polymorphisms which were analyzed by PCR and RFLP.
RESULTSIt showed that there was no significant difference in frequencies of this genotypes of CYP1A1 MSPI between the two groups. The frequency of GST-M1 null (0/0) genotype was higher in the case group than in the control group, with an OR of 1.38 (95% CI 0.81 - 2.38), but there was no statistical significance. However, combination of several genotypes was strongly associated with lung cancer. There was a synergistic interaction between the m2m2 genotype of CYP1A1 MSPI and GST-M1 (0/0) genotype, with an OR of 2.47 (95% CI 1.03 - 5.90).
CONCLUSIONThe combination of two genetic polymorphisms significantly increases the risk of lung cancer.

Our previous results have demonstrated that insulin reduces myocardial ischemia/reperfusion (MI/R) injury and increases the postischemic myocardial functions via activating the cellular survival signaling, i.e., phosphatidylinositol 3-kinase (PI3-K)-Akt-endothelial nitric oxide synthase (eNOS)-nitric oxide (NO) cascade. However, it remains largely controversial whether c-Jun NH2-terminal kinase (JNK) is involved in the effects of insulin on MI/R injury. Therefore, the aims of the present study were to investigate the role of JNK, especially the cross-talk between JNK and previously expatiated Akt signaling, in the protective effect of insulin on I/R myocardium. Isolated hearts from adult Sprague-Dawley rats were subjected to 30 min of regional ischemia and followed by 2 or 4 h of reperfusion (n=6). The hearts were pretreated with PI3-K inhibitor LY294002, or phosphorylated-JNK inhibitor SP600125, respectively, then perfused retrogradely with insulin, and the mechanical functions of hearts, including the heart rate (HR), left ventricular developed pressure (LVDP) and instantaneous first derivation of left ventricular pressure (+/-LVdp/dt(max)) were measured. At the end of reperfusion, the infarct size (IS) and apoptotic index (AI) were examined. MI/R caused significant cardiac dysfunction and myocardial apoptosis (strong TUNEL-positive staining). Compared with the control group, insulin treatment in MI/R rats exerted protective effects as evidenced by reduced myocardial IS [(28.9 +/- 2.0)% vs (45.0 +/- 4.0) %, n=6, P<0.01], inhibited cardiomyocyte apoptosis [decreased AI: (16.0 +/- 0.7) % vs (27.6 +/- 1.3) %, n=6, P<0.01] and improved recovery of cardiac systolic/diastolic function (including LVDP and +/-LVdp/dt(max)) at the end of reperfusion. Moreover, insulin resulted in 1.7-fold and 1.5-fold increases in Akt and JNK phosphorylation in I/R myocardium, respectively (n=6, P<0.05). Inhibition of Akt activation with LY294002 abolished, and inhibition of JNK activation with SP600125 enhanced the cardioprotection by insulin, respectively. And the abolishment by LY294002 could be partly converted by SP600125 pretreatment. In addition, SP600125 also decreased the Akt phosphorylation (n=6, P<0.05). These results demonstrate that insulin simultaneously activates both Akt and JNK, and the latter further increases the phosphorylation of Akt which attenuates MI/R injury and improves heart function; this cross-talk between Akt and JNK in the insulin signaling is involved in insulin-induced cardioprotective effect.

BACKGROUND: There are various treatment methods for osteonecrosis of the femoral head (ONFH) and collapse, but conservative treatment is invalid. Once femoral head collapse occurs, the development is irreversible. Our previous research has shown that local administration of zoledronic acid can prevent necrotic femoral head collapse. Moreover, bone marrow mononuclear cells obtain satisfactory short-term efficacy in the treatment of ONFH. OBJECTIVE: To investigate the curative efficacy of local administration of mononuclear cell, platelet-rich plasma and zoledronic acid for the prevention and treatment of early ONFH and collapse. METHODS: This prospective, single-center, randomized, parallel, controlled clinical trial was conducted at the Chinese PLA General Hospital, Beijing, China. One hundred patients with ONFH (stages I-II by Ficat and Arlet classification) were enrolled and randomly assigned into either the treatment group or control group (n=50 per group). Patients were given an injection of mononuclear cell, platelet-rich plasma and zoledronic acid into the necrotic femoral head, or drilling decompression at the necrotic area. Patients in both groups were then followed up for 4, 8, 12, and 18 months. The primary outcome measures were the blood supply, osteogenesis and appearance of the necrotic femoral head observed on hip perfusion by dynamic MRI, CT restruction of the hip joint and radiography of the hip joint, as well as Harris hip scores and numerical rating scale scores. Secondary outcome measures included SF-36 Health Survey and Activities of Daily Living scores. DISCUSSION: The outcomes of this trial have provided quantitative data for analyzing the effectiveness of local administration of mononuclear cell, platelet-rich plasma and zoledronic acid on ONFH and collapse. Written approval for this protocol was obtained from the Ethics Committee of the Chinese PLA General Hospital in China (approval No. S2015-082-01). Participants and their families are informed of the study protocol and procedures, and signed an informed consent. The study was in accordance with the guidelines of the Declaration of Helsinki, formulated by the World Medical Association. Trial began in January 2015 and will be completed in December 2017. Trial results will be published in scientific reports, or in peer-reviewed journals. This trial was registered with the ClinicalTrials.gov identifier: NCT02721940. Patient recruitment is ongoing.

Objective To explore the clinical value of double-balloon enterocopy (DBE) in diagnosis of small intestinal diseases. Methods The clinical and endoscope image data of 231 patients with suspected small bowel disease who underwent DBE from January 2008 to May 2016 were analyzed. Result 231 patients received 257 times of DBE examination, 112 of them were performed by oral and 93 by anal route, 26 patients were underwent by both approaches. The detection rate of intestine diseases was 64.9% (150/231), include 33 cases (14.3%) of nonspecific enteritis, 27 cases (11.7%) of crohn's disease, 19 cases (8.2%) of ulcer, 13 cases (5.6%) of intestinal vascular malformation, 12 cases (5.2%) of small intestinal stromal tumor. The lesion detection rate in obscure abdominal pain and obscure gastrointestinal bleeding were 59.6% (62/104) and 67.0% (63/94). In all patients, there were 1 case of small bowel perforation, the remaining patients had no serious complications such as bleeding and perforation. Conclusion The positive detection rate of double-balloon enteroscopy examination is high, and the double-balloon enteroscopy examination is relatively safe. So, double-balloon enterscopy examination has high diagnostic value for detecting small intestine diseases.

OBJECTIVEIn order to study the diagnosis and treatment of HBV and HCV infection.
METHODSWe retrospectively analysed clinical data of 680 patients with cholangiocarcinoma from 1995 to 2001 and stated by SPSS software.
RESULTS(1) The fastigium of cholangiocarcinoma was 60 - 65 years old. The incidence of cholangiocarcinoma was higher in aged males and the sex ratio (male:female) was 1.36:1. (2) The proximal cholangiocarcinoma was most (41.6%) and distant cholangiocarcinoma was secondly (28.7%). (3) Most patients of cholangiocarcinoma were late. The resection rate was low and the rate of radical operation was 21.6% (147/680). (4) The incidence of proximal cholangiocarcinoma was higher in the positive Serologic marks for HBV and HCV and course of diseases was short. Moreover, the pathology of. positive Serologic marks for HBV and HCV trended to low-differentiation and invasion, metastasis and the resection rate was lower.
CONCLUSIONSCholangiocarcinoma is common in the aged males. The infection of HB(C)V and hilar cholangiocarcinoma are correlated and incline to the proximal bile duct. The hilar cholangiocarcinoma infected HB(C)V may have higher malignant degree in biological characteristics and more badly prognosis.
