Objective To explore the morbidity, manifestation, pathogenesis and diagnosis of acquired immune deficiency syndrome( AIDS)-related lesions in digestive system. Methods The complete history interview, physical examination and diagnostic test were made in a total of 1000 heroin addictors with intravenous injection. Seventy-two of them were selected as AIDS based on the diagnosis criteria on HIV/AIDS of Centers for Disease Control(CDC) (CD4+ T cell count lower than 400/?l and human immunodeficiency virus ( HIV) load higher than 400 copies/ml). Results Main clinical manifestations of AIDS were persistent low fever, diarrhea, progressive exhaustion, opportunistic infection, tumorgenesis and multiple organ impairment. The morbidity of AIDS-related lesions in digestive system ranged from 1.4% to 98. 6%. Oropharyngeal and gastrointestinal lesions occurred in 71 cases (98.6%), while hepatic, biliary and pancreatic impairment occurred in 59 cases (81. 9%). Conclusions AIDS-related lesions in digestive system are common in AIDS patients which are mainly caused by HIV invasion, opportunistic infection, tumorgensis and immune system impairment.

Objective To study the expression and its significance of Platelet-derived growth factor(PDGF) and Collagen type Ⅰ (Col- Ⅰ) mRNA in hepatic tissue in mice exposed to arsenic in drinking water. Methods Fifty mice were divided into control group, sodium arsenite group(iAs3+ group, 300 mg/L) and sodium arsenate group (iAs5+ group, 300mg/L) at random. The mice were sacrificed after 10 months for liver function test (ALT, AST and GLB examined by automatic biochemical analyzer) and pathologic examinations. Masson staining and immunohistochemical SABC methods were used. Through the result of Masson staining fibrosis semi-quantitative analysis of the fibrosis number was carried out in the per unit area. Using immuonhistochemical SABC methods, the expression of PDGF and Col- Ⅰ was detected. Results ①Serum ALT was statistically significant among control group [(36.67±3.51) U/L], iAs3+ group[(61.46±13.85) U/L] and iAs5+ group[(43.31±4.21) U/L, F= 6.56, P < 0.05], especially between the control and iAs3+ group (P < 0.05) ;Serum AST had a statistical significance among control group [(135.00 ± 20.42)U/L], iA3+ group [(510.86 ± 59.01)U/L] and iAs5+ group[(258.93 ± 22.40) U/L, F= 83.36, P < 0.05] ;Serum GLB had no statistical significance among control group [(20.86 ± 0.61)g/L], iAs3+ group [(26.94± 3.73)g/L] and iAs5+ group[(24.59 ± 5.27)g/L, F = 2.80, P < 0.05]. ②Masson staining revealed notable liver cell necrosis, regeneration, infiltration of inflammatory cells in portal area. Masson staining Semi-quantitative results showed significantly increasing size of fibrosis in model group. Compared with control group(0.069 ± 0.013) and iAs5+ group(0.143 ± 0.122), fiber hyperplasia of iAs3+ group(0.192 ± 0.108) had statistical significance (F = 1.91, P < 0.05). ③Immunohistochemistry results showed higher expression of PDGF in the portal area, sepetal and preisinus cells in model group. The heavy expression of Col- Ⅰ distributed in the surrounding of blood vessels and bile duet and along portal wall extensting to the liver in model group. Semi-quantitative results showed that PDGF among control group(202.79 ± 7.46), iAs3+ group(174.38 ± 7.71) and iAs5+ group(177.64 ± 7.81) had a statistical significance(F= 102.91, P < 0.05);Col-Ⅰ had a statistical significance among control group(200.11 ± 7.46), iAs3+ group (176.47±10.20) and iAs5+ group (177.378 ±7.948, F = 78.51, P < 0.05). Conclusions Exposed in oral drinking arsenic, mice can develop hepatic injury and hepatic fibrosis. The PDGF and Col-Ⅰ play significant effects on the process of hepatic fibrosis caused by oral drinking arsenic exposed mice.

Objective Investigate the clinical efficacy of treating retreated smear-positive tuberculosis patients with conventional anti-tuberculosis chemotherapy combined with levofloxacin. Methods Divide 60 retreated smear-positive tuberculosis patients registered in our hospital between October 2012 and October 2014 into two groups using random number table method: levofloxacin group and conventional treatment group. Each group contains 30 patients that were treated for 9 months , and the efficacy the both treatment methods were compared. Results The sputum conversion rate in the levofloxacin group is 93.33% and 96.67% after treating for 6 months and 9 months , respectively; which are substantial higher than that of the conventional treatment group with sputum conversion rate of 70% and 73.33% after 6 months and 9 months of treatment , respectively (P < 0.05). The absorption rate of the levofloxacin group is significantly higher than that of the conventional treatment group (P < 0.05). The cavity improvement rate of the levofloxacin group is 73.33%, which is significantly higher than that of the conventional treatment group (33.33%) (P < 0.05). The clinical efficacy of the LVFX group is substantially higher than the routine treatment group (P < 0.05). The overall effectiveness of LVFX group reached 100% , which is significantly higher than that of the conventional treatment group (86.67%) (P < 0.05). Conclusions Levofloxacin combined with conventional anti-tuberculosis chemotherapy can effectively improve the clinical efficacy in the treatment of tuberculosis.

OBJECTIVETo investigate the quality of life of cleft lip and/or palate children's parents and discuss the factors to provide the oretical basis for improving the quality of life of these parents and promoting the healthy growth of children with cleft lip and/or palate.

METHODSA total of 115 parents whose children had cleft lip and/or palate surgery treatment were selected as the experiment group, and another 198 parents (with healthy children having a similar age with those in the experiment group) as the control group. The experiment group was divided into three subgroups according to different types of cleft lip and/or palate: cleft Lip (CL), cleft palate (CP), cleft lip and palate (CLP). The experiment group and the control group were both divided into four subgroups according to age: 0-1, 1-3, 3-6 years old, and more than 6 years old. The experiment group and the control group were both divided into three subgroups according to education: junior middle school and the following, high school and technical secondary school, junior college degree or above. The GQOLI-74 scale was selected to assess the experiment group and the control group. SPSS 16.0 software was used to analyze data.

RESULTS1) The experiment group had no significant difference with the control group in terms of the overall score and the scores of various children ages. 2) The scores of every item had no significant difference in CL, CP, CLP subgroup (P > 0.05). 3) The quality of life scores and scores of psychological function dimension and social function dimension of parents with 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P<0.05). The scores of social function dimension of parents with 0-1, 1-3, 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P < 0.05). The other items had no significant difference. 4) The scores of material life dimension and social function dimension of parents with junior college degree or above were higher than those of parents with junior middle school degree and the following (P < 0.05). The scores of social function dimension of parents with high school and technical secondary school degree were higher than those of parents with junior middle school degree and the following (P < 0.05).

CONCLUSIONNo difference was observed in the quality of life between cleft lip and/or palate children's parents and normal group. The parents with the low age children with cleft lip and/or palate and low-levels of education need more help and support to improve quality of life.

Objective To study epidemiology, clinical findings, diagnosis and treatment of sepsis caused by Vibrio vulnificus. Method Patientss with Vibrio vulnificus sepsis were collected from 1995 to 2008. The medical records including epidemiological and clinical data were analyzed. Results The male-to-female ratio of 34cases was 4.7:1 and 76. 5% of these patients suffered from chronic liver disease. Most patients occurred from April to October with signs of abrupt fever, characteristic cutaneous lesions, hypotension and progressive multiple organ disfunction syndrome (MODS). The mortality was over 47.1% . The criteria proposed for early diagnosis of Vibrio vulnificus sepsis were abrupt onset with fever during the period from April to November, characteristic cutaneous lesions, such as the most commonly occurred haemorrhagic bullae on the extremities or even extensive necrosis of skin and muscular tissue, progressive hypotension or shock accompanied by MODS, pre-existing liver disease or chronic abuse of alcohol, and consumption of raw seafood or exposure to seawater within 12 week. Early administration of the third-generation cephalosporins with the quinolones in full dosage, aggressive wound debridement,appropriate dermoplasty and supportive care contribute to a better outcome. Conclusions Vibrio vulnificus sepsis progresses rapidly with high mortality. Early diagnosis, rapid treatment with prompt antibiotics and aggressive surgery treatment are very important to improve the outcome.

BACKGROUND: The incompatible reaction may occur after islet transplantation, which affects the survival and functions of cells. OBJECTIVE: To explore the islet cells injury and its causes during islet transplantation. METHODS: The pancreases of voluntary, brain death, donors were isolated by collagenase, and the islet cells injury was measured with different cold ischemia times. The islet cells were cultured with blood as follow: HLA matching group: recipient whole blood + islet cells, recipient whole blood + islet cells + heparin; HLA mismatching group: recipient whole blood + islet cells, recipient whole blood + islet cells + heparin; Control group: recipient whole blood + RPMI1640. The potential injury to islet cells was observed. RESULTS AND CONCLUSION: The pancreases were smoothly obtained. The activity of islets may be more than 80% within 5 hours of ischemia preservation time, which was less than 19% if the cold ischemia preservation time was over 8 hours. When human islets were exposed to human blood, it will induce a rapid consumption of blood cells, no matter HLA matching or HLA mismatching. After adding heparin into the blood, these events were avoided. At 24 hours of in vitro culture, the number of survival islet cells in the HLA matching group was greater than that of the HLA mismatching group (P < 0.05). The results described that cold ischemia time affects islet cells activity, reduce the cold ischemia preservation time within 5 hours and HLA typing are conductive to enhance the quantity of living islets.
