Objective To assess the relationship between human papillomavirus (HPV) and extrageni-tal Bowen's disease. Methods Regular PCR with consensus primers for LI region as well as mix primers and nested PCR were performed to detect the DNA of a broad range of cutaneous and mucosal HPV types in tissue samples from lesions of 41 patients with extragenital Bowen's disease and from normal skin of 48 human controls. Semiquantitative PCR and tyramide-based in situ hybridization (ISH) were also conducted to determine the load and localization of HPV DNA in HPV-positive samples. Results HPV DNA was detected in lesions from 5 (12%) of the 41 patients with extragenital Bowen's disease. Of the 5 HPV-positive patients, 3 carried mucosal HPV types (HPV16 in 2 cases, HPV 33 in 1 case) with a viral load of 101 to 103 copies, 2 cutaneous HPV types (HPV27 in 1 case and HPV76 in 1 case). As ISH showed, there was a generalized expression of mucosal HPV DNA in most tumor cell nuclei but not in peritumoral normal tissue, and no expression of cutaneous HPV DNA was observed in lesions. HPV DNA was detected in 1 (2.1%) control tissue sample, which proved to be epidermodysplasia verruciformis-associated HPV23. There was no significant difference in the detection rate of HPV DNA between the patients and controls. The viral load of cutaneous HPV types amounted to 10-2 to 10-3 copies in the 2 patients, which was similar to that of HPV 23 in the normal control. Conclusion Mucosal HPV types may be closely associated with the development of extragenital Bowen's disease.

Objective To investigate the influence of different diluents(physiologic saline, dis-tilled water and human inactivated serum) on measurement of 15 items of biochemical parameters.Methods Fifteen items of biochemical parameters [alanine transaminase(ALT), aspartic transaminase (AST), alkaline phosphatase( ALP), gamma glutamyl transpeptidase ( GGT), creatine kinase ( CK),lactate dehydrogenase(LD), hydroxybutyrate dehydrogenase(HBDH), total bilirubin(TBIL), direct bilirubin(DBIL), total bile acid(TBA), ereatinine(Cr), uric acid(UA), eholesterol(CHO), glucose (GLU), and blood urea nitrogen(BUN)] were chosen. For each parameter, 45 serum samples with different eoncentrations of the parameter were collected. After diluted with different diluents(physio-logic saline, distilled water or human inactivated serum), the serum samples were detected by applying the fully automated biochemical analyzer. The mean value was calculated and statistical analysis was performed. Results There were some differences of detection results when the specimens were diluted with different diluents. ALT, AST, GGT, DBIL, and HBDH serum samples could be diluted by 10 times with physiologic saline, distilled water or human inactivated serums ALP and TBA serum sam-ples could only be diluted with inactivated serum, otherwise its result would be lower; GLU, TBIL samples could be diluted with distilled water and inactivated serums for BUN, CR, UA, CK, LDH,and CHO samples, physiologic saline or human inactivated serum might be optimal; if distilled water was chosen, the results of other parameters tented to decline except UA. It was BUN was improper to dilute the BUN samples with distilled water. In addition, there was no significant difference between the items diluted by 5 times and 10 times with physiologic saline. All the 15 items could be diluted with inactivated serum. Conclusion The inactivated serum should be the first choice of diluents to e-nure the accurate results of biochemical parameters. If the prepared inactivated serum is absent, we may choose other diluents according to the above-mentioned results.

Objective:To investigate the impact of adding human menopausal gonadotropin (hMG) for in vitro fertilization-embryo transfer pregnancy outcomes in a standard population of non-advanced age with normal ovarian reserve function using a long follicular phase protocol.Methods:Clinical data of 489 patients with normal ovarian reserve function, who were admitted from January 2018 to January 2020 in the Affiliated Hospital of Guizhou Medical University and underwent in vitro fertilization for the first time with the long follicular phase protocol in fresh cycles, were retrospectively analyzed. The patients were divided into three groups according to whether or not to add urine-derived hMG and the timing of addition: non-addition group (group A), medium-term hMG group (group B1), whole course hMG group (group B2); the laboratory parameters of each group were observed, and the effect of ovulation induction drugs and pregnancy outcomes were compared.Results:The ages of B1 and B2 groups were significantly higher than that of group A ( P=0.019 and P=0.011). The basal FSH level of group B2 was significantly higher than those of group A and group B1 ( P<0.01 and P=0.006), and the basal FSH/LH ratio of group B2 was significantly higher than that of group B1 ( P=0.009). Antral follicle counts of group A and group B1 were significantly higher than that of group B2 ( P=0.007 and P=0.017). The superior embryo rate of group B2 [(47±27)%] was significantly higher than that of group A ( P=0.017). The embryo implantation rate of group B1 was significantly lower than those of group A and group B2 ( P=0.043 and P<0.01). The clinical pregnancy rate of group B2 [76.7% (155/202)] was significantly higher than those of group A ( P=0.039) and group B1 ( P<0.01). The live-birth rate of group B2 [67.3% (136/202)] was significantly higher than those of group A ( P=0.017) and group B1 ( P=0.001). Conclusions:For non-advanced aged patients with normal ovarian reserve function, the long protocol of follicular phase is suitable for those with relatively low ovarian reserve function. Adding hMG in the whole course of ovulation induction after gonadotropin-releasing hormone agonist reduction could improve the pregnancy outcomes by improving the quality of embryos.

Objective To study the changes of CDH1 gene promoter CpG island methylation and its clinical significance in patients with esophagus and stomach double primary carcinoma(ESDC).Methods The expression of CDH1 gene methylation in cancerous tissues and adjacent cancerous tissues in 18 cases of ESDC were detected using methylation-specific PCR method. Results Eighteen patients were endoscopically diagnosed as ESDC between Jan. 2007 and Sep. 2009 in the 4th Hospital Affiliated to Hebei Medical University. The positive methylation of CDH1 gene in tissues of esophageal squamous cell carcinoma (ESCC)and adjacent cancer were 66.7% and 33. 3%, respectively, with significant difference (χ2= 4. 167, P = 0. 031). Whereas the positive methylation of CDH1 gene in tissues of gastric carcinoma (GA) and adjacent cancer were 77.8% and 44.4%, respectively, without statistical difference (χ2=1.786, P= 0. 180). There was no significant difference (P=0. 500) in positive rate of CDH1 gene methylation between ESCC tissues and GA tissues in same individual with ESDC. For 18 patients with ESDC, consistent change of CDH1 methylation in tissues of two kinds of cancers was found in 16 patients with a total agreement of 88.9 % (positive agreement of 66.7 % and negative agreement of 22. 2%). Statistical analysis showed a significant correlation between two groups (P = 0. 005). Conclusion In patients with ESDC, there is a high consistency of CDH1 methylation change, between ESCC and GA,which suggests that two kinds of cancer may have similar risk factors and molecular mechanisms.

ObjectiveTo evaluate the prevention and treatment of primary graft dysfunction (PGD) after lung transplantation (LTx).MethodsWe retrospectively analyzed clinical data of108 cases of lung transplantation from September 2002 to June 2011. All the recipients were given continuous monitoring of invasive arterial pressure,pulmonary artery pressure and (or) central venous pressure and artery blood gas analysis and chest X-ray examination postoperatively.The negative fluid balance of the recipients in the first 3 days was maintained.The inspired oxygen (FiO2) or ventilator parameters was adjusted according to the arterial oxygen tension (PaO2) and (or) oxygen saturation,to prevent the occurrence of PGD.Once PaO2/FiO2 sharp decline (less than 200),and chest X-ray showed higher density of the lower transplanted lung fields in the early postoperative period,PGD could be diagnosed when acute rejection,venous anastomotic obstruction,cardiogenic pulmonary edema and pulmonary infections were excluded.According to the standards set by the International Association of Heart and Lung Transplantation,PGD is divided as 0,1,2 and 3.Different levels of PGD were treated by ventilatory support,negative fluid balance,extending the treatment time of the ventilator,the use of pulmonary vasodilators,such as prostaglandin E1and the use of ECMO.Results PGD occurred in10 cases,and the incidence rate was 9.3%. 6 cases were given conventional ventilatory support for (285.8 + 238.6) h (Two cases obtained reversal of PGD,and four cases died) ; the rest four cases were given ECMO (Two cases were supported by ECMO in 24 h after the occurrence of PGD and had a long-term survival after a successful reversal of PGD,and the rest two cases died from acute renal failure and multiple organ failure induced by PGD on the 8th and11th day of the application of ECMO due to the late application of ECMO (after 24 h).ConclusionThe high incidence of PGD causes high mortality perioperatively after lung transplantation.Preventing PGD can improve the survival rate of the lung transplant patients.Once PGD happens,appropriate treatment should be given as soon as possible.

Objective To evaluate clinical effect of simultaneous kidney-pancreatic transplantation(SKPT) with portal venous and enteric drainage. Method Between June 2001 and June 2004, six insulin-dependent diabetes mellitus(IDDM) and renal failure patients underwent this procedure. The venous drainage of the graft was established between donor′s portal vein and recipient′s superior mesenteric vein. The exocrine secretion was drained into proximal jejunum via side-to-side anastomosis between donor′s duodenum and recipient′s proximal jejunum. Steroids, mycophenolate mofetil, tacrolimus and Zenapax were used as immunosuppressants. Results Procedures were successful in all 6 cases. Excellent renal function and euglycemia were achieved in 4 cases. Follow-up of 4-34 months on the 4 survivers found excellent kidney-pancreatic function without any rejection episode. Two patients died perioperatively due to sepsis secondary to pancreatic leakage and drug toxicosis of excessive FK506. Conclusion Our preliminary experience suggests that simultaneous pancreas-kidney transplantation with enteric and portal drainage is reliable procedure for the treatment of IDDM with renal failure.

OBJECTIVETo document morphological changes in hepatic microcirculation in liver tissue with hepatitis B and the pathogenesis of hepatic microcirculatory disturbances.
METHODSLiver tissue samples were obtained from patients with hepatitis B by liver biopsy. These samples were examined with a light microscope and transmission electron microscope.
RESULTSHepatic microcirculatory disturbances existed in patients with hepatitis B, including those with normal liver function, manifested by red blood cell aggregation in sinusoids seen under light microscope and sinusoidal capillarization seen under electron microscope. Weibel-Palade bodies in sinusoidal endothelial cells were seen in 26 out of 53 cases. Intimate contacts were found between lymphocyte/Kupffer cells and sinusoidal endothelial cells.
CONCLUSIONSHepatic microcirculatory disturbances exist in patients with hepatitis B. The appearance of Weibel-Palade bodies in sinusoidal endothelial cells may be a key step in the development of hepatic microcirculatory disturbances.
