Objective: To explore the feasibility and applicability of a novel cavernosum-free surgical technique for concealed penis of children. Methods: From June 2017 to August 2017, 38 boys with concealed penis were treated using our new cavernosum-free surgical technique. The median age was 8.5 years(4-13 years). The technique consisted of 3 steps: Step 1, making a horizon incision and expose the glans; Step 2, suturing skin of penis to the corresponding side of inguinal ligament medial crus at 2 and 10 o′clock without fixing of cavernosum.Step 3, pruning the foreskin and suturing together. No catheter was placed after surgery. Results: All the patients were able to urinate 2 to 6 hours after operation. The numeric rating scales score of postoperative pain was 1-3. Wound dressing was removed 5 to 7 days post-operatively. All of the parents had good cosmetic appearance, penis stretched naturally without deflection. The length of penis increased more than 3.0 cm on average after operation.Edema was observed in 3 cases, but disappeared in 5-7 days.No serious complications such as bleeding or winding occurs. Conclusions The novel cavernosum-free surgical technique is easy to perform. It provides a safe and effective technique for concealed penis of children.

Objective To compare the difference of the protein about the patient of hepatitis B who received adefovir dipivoxil(ADV)therapy,and seek the useful biomarker of effective therapy.Methods We used the two-dimensional gel electrophoresis technology to examine HBV infected serum samples aiming at searching protein's alteration after ADV therapy.Results After 1 year's treatment,haptoglobin, haptoglobin 2-alpha raised and alpha-l-antitrypsin precursor,Factor B,Chain B,transthyretin,glutathione peroxidase,alpha-2-HS-glycoprotein,retina]binding protein,retinol-binding protein precursor, apolipoprotein,apolipoprotein A-I precursor fell in viral response patients.Transthyretin raised and leucine- rich alpha-2-glyeoprotein,haptoglobin,alpha-2-actin,apolipoprotein A-I precursor fell in none viral response patients.To compare two groups:apolipoprotein A-I have the same change and haptoglobin, transthyretin have the opposite change.Conclusion Proteomics study can find the alteration of protein during the ADV treatment,and is helpful to searching the predictable biomarker to ADV.

Objective To investigate the feasibility and effectiveness of endovascular treatment of posterior communicating artery aneurysm (PcoAA)in keeping the fetal posterior cerebral artery (FPCA) patency. Methods Form January 2014 to December 2015,14 patients with ruptured PcoAA enrolled retrospectively were treated with endovascular embolization. Six of them were treated with simple coil embolization,3 with stent-assisted coil embolization,3 with double catheter-assisted coil embolization,1 with stent-assisted coil embolization + double catheter technique,and 1 with Y-stent in Yijishan Hospital, Wannan Medical College. The immediate embolization rate of PcoAA (using Raymond grade),prognosis of the patients (the modified Rankin scale score at 6 months after procedure),complications,and imaging follow-up results were analyzed. Results The success rate of coil and stenting was 100% . All the stents were accurately released in place without displacement. The immediate Raymond grading of the aneurysms displayed that Raymond grade Ⅰ was in 8 cases,Raymond grade Ⅱ was in 4 cases,and Raymond grade Ⅲ was in 2 cases. All FPCA were kept patent. A coil protruded into internal carotid artery in one case during the procedure. Others did not have any complications,such as intraoperative cerebral vasospasm,in-stent thrombosis,and rupture. All 14 patients were followed up for 3 -24 months after procedure. Two had recurrence. Both were aneurysms embolized with coils only. No rebleeding and ischemic
complications were observed. The modified Rankin scale scores in 13 cases were 0 -2 at 6 months after procedure,1 was 4. Conclusions Endovascular embolization for the treatment of PcoAA and keeping FPCA patency are safe and feasible. A variety of endovascular treatment modalities are necessary in order to keep FPCA patency.

AIMTo investigate the penetration kinetics of xanthotoxin in human skin and stratum corneum.

METHODSThe penetration experiments were accomplished by the deposit of ethanolic xanthotoxin solution onto human skin and stratum corneum mounted on Franz cells. The diffused xanthotoxin in the receptor solution (1.4% human serum albumin) and the retained amount in the skin and in the stratum corneum after 24 h exposure were quantified by using high performance liquid chromatography.

RESULTSXanthotoxin flux was increased with the concentration deposited onto the human skin, and when the concentration is above 2.5 mg x mL(-1), there is no influence on the xanthotoxin flux. Similar results were obtained from the stratum corneum. And the peak time for the flux in the stratum corneum was preceded about 6 h earlier than that of the whole human skin. The retained xanthotoxin amount after 24 h exposure in the skin and in the stratum corneum increased according to the concentration deposited and has the tendency to saturate. The lag time of ethanolic xanthotoxin solution in the whole human skin is significantly higher than that in the stratum corneum (P < 0.05).

CONCLUSIONThe characteristics of penetration kinetics of xanthotoxin will provide the information for concentration choice of topical formulation and give a reference for ultra violet A (UVA) irradiation time confirmation.

OBJECTIVETo investigate the differences of clinical manifestation and therapy of organophosphorus pesticide poisoning (OPP) between oral exposure and occupational exposure in field work.

METHODSFrom July 2007 to July 2010, 85 patients with acute severe OPP were treated in a hospital, which were divided into oral poisoning group (51 cases) and non-oral poisoning group (34 cases). The differences of clinical manifestations, curative effects and prognosis between two groups were compared.

RESULTSThe rates of myoclonus and ataxia in cases with moderate poisoning of oral poisoning group were 86.4% and 90.9%, which were significantly higher than those (50.0% and 55.0%) of non-oral poisoning group (P<0.05 or P< 0.01). The rates of myoclonus, lung fluid and coma in cases with severe poisoning of oral poisoning group were 100.0%, 89.7% and 93.1%, respectively, which were significantly higher than those (71.4%, 64.3% and 50.0%) of non-oral poisoning group (P<0.05). The mean detoxification hours in cases with moderate poisoning and cases with severe poisoning of non-oral poisoning group were (35.0 +/- 6.2) and (45.0 +/- 11.1) hours which were significantly lower than those [(49.0 +/- 7.7) and (77.0 +/- 10.3) hours] in cases with moderate poisoning and cases with severe poisoning of oral poisoning group (P<0.05). In 24, 48 and 72 h after treatment, the cholinesterase (ChE) activities of non-oral poisoning group were higher than those of oral poisoning group (P< 0.05 or P<0.01). The used doses of pyraloxime methylchloride (PAM-Cl) or atropine and the used total dose of atropine in non-oral poisoning group were lower than those in oral poisoning group (P<0.05 or P<0.01).

CONCLUSIONSThe clinical manifestation of non-oral poisoning group is different from the clinical manifestation of oral poisoning group due to the high morbidity of OPP occurred at field site in summer. The used doses of atropine and PAM-Cl are less and the ChE activity recovers quickly for non-oral poisoning group.

OBJECTIVETo investigate the relationship between the Model for End-Stage Liver Disease (MELD) with Child-Pugh scoring, and the prognosis of patients with decompensated liver cirrhosis.

METHODS110 patients with decompensated liver cirrhosis were graded with MELD formula and with Child-Pugh. The death rate was observed within three months.

RESULTS31 patients died within 3-months. The mortality of patients whose MELD scores were between 10 approximately 19, 20 approximately 29, and > or = 30 was higher than those with MELD < or = 9 (The mortality of those with MELD less than 9, 10 approximately 19, 20 approximately 29, or > or = 30 was 11.76%, 38.18%, 64.71%, 75.00% respectively). The mortality of patients whose MELD scores were > or = 18 was higher than those with MELD < 18 (The mortality of those with MELD < 18, MELD > or = 18 was 26.58%, 58.06% respectively. chi2 = 9.643). The mortality of Child A, B, C was 14.89%, 42.55%, 75% respectively.

CONCLUSIONBoth MELD and Child-Pugh scores can accurately predict the short-term prognosis of patients with decompensated liver cirrhosis.

BACKGROUNDTo investigate natural history of hepatitis C virus (HCV) infection and related factors in China.

METHODSTotally 41 women infected with HCV 10-15 years ago were evaluated in this study. Their clinical manifestations were recorded and sera tested for alamine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (gamma-GT), alkaline phosphatase (ALP), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (ALB), and alpha-fetoprotein (alpha-FP), as well as virus markers. The B-type ultrasound examination was performed on the liver, gall bladder, spleen and pancreas. For virus markers, HCV RNA was detected with fluorogenic-quantitative polymerase-chain-reaction, HBsAg and anti-HCV antibody, with enzyme-linked immunosorbent assay (ELISA).

RESULTSTen to 15 years after infection, the infection was cleared spontaneously in 8 cases (19.51%); 73%(30/41) cases had signs at present, 32% (13/41) cases had mild ALT and/or AST elevation. On ultrasound examination, 83%(34/41) had mild degree 17%(7/41) moderate degree changes of the viral hepatitis.

CONCLUSIONWomen with HCV infection for 13 +/- 1 (10-15) years after transfusion had slight hepatic inflammation. A part of them had cleared the virus spontaneously.

Objective To assess the burden of clonorchiasis and identify its temporal and spatial changes in China, thus to provide insights into the control and prevention of the diseases. Methods The disability-adjusted life years (DALYs) was employed as the primary indicator for the disease burden. The prevalence data of Clonorchis sinensis infection were obtainted from the three national surveys on important human parasitic diseases in China, conducting during the period from 1988 to 1922, from 2001 to 2004 and from 2014 to 2016, respectively, and the demographic data from National Bureau of Statistics of China. DALYs of clonorchiasis were calculated and the temporal changes were analyzed at both national and provincial levels, using the disability weight (DW) obtained from a community study in China. Sensitivity analysis was carried out to compare the resulted DALYs of China calculated under the method adopted in this study and that calculated with other commonly used methods. Results The national burden of clonorchiasis was 489174.04 [95% confidence interval (CI): (391648.87, 597509.87)] DALYs in China in 2016, indicating 0.36 [95% CI: (0.28, 0.43)] DALYs per 1 000 populations. The regions with a high burden of clonorchiasis were concentrated in southern China and northeastern China, and the provinces with the three highest burdens of clonorchiasis included Guangxi Zhuang Autonomous Region, Guangdong Province and Heilongjiang Province, which accounted for 91.18% of total burdens of clonorchiasis in China. During the periods of the three national surveys on important human parasitic diseases in China, the national burden of clonorchiasis was found to show a tendency of first rise and then decrease in China; however, the burden of clonorchiasis has recently shown a tendency towards a rise in Guangxi Zhuang Autonomous Region, Heilongjiang Province and Jiangxi Province. Sensitivity analysis showed that the calculation of diseases burden with age-stratified prevalence of clonorchiasis was similar to that of our method without age stratification; however, the burden estimates calculated only based on the DW of the severe symptoms were much lower than our estimates. Conclusions The burden of clonorchiasis is high in China, with a large regional difference. Recently, the overall burden of clonorchiasis has shown a tendency of decline in China; however, there is a tendency towards a rise in some provinces. Therefore, the control of clonorchiasis requires more adaptations to local circumstances.
