Objective To analyze the detection results and clinical significance of human papillomavirus (HPV) DNA genotypes in the patients with condyloma acuminate (CA)and high risk (HR)population of CA and normal population of physical examination (PE).Methods 527 cases of CA patients (CA group),208 cases of HR (HR group)and 197 cases of normal PE (PE group)in the outpatient were selected.The human HPV DNA genotypes in 932 samples of different population were examined with HybriMax;the positive detection rates,the preponderance types of HPV and the multiple genotype infection in three groups were analyzed.Results The HPV positive rate in CA group was 98.29% and the preponderance types were HPV 6,11,33,and 52 genotypes.The HPV positive rate in HR group was 26.44% and the preponderance types were HPV 6,11,33,and 66 genotypes.The HPV positive rate in PE group was 5.58% and the preponderance types were HPV 6 and 11 genotypes.The difference in the positive detection rates of HPV between HR and PE groups had statistical significance (P < 0.05 ). The positive rates of multiple genotype infection in CA group and HR group were 36.43% and 5.77%,respectively,and there was significant difference (P < 0.01 ); the positive rate of double infection was the highest (18.41%), followed by the positive rate of triple heavy infection (11.20%) and the positive rate of septuple heavy infection (0.38%).Conclusion The HPV 6 and HPV 11 of low-risk HPV genotypes are the most common genotypes in different population. The HR group and PE group are all asymptomatic but the positive detection rate of HPV in HR group is higher than that in PE group. The positive rate of HPV multiple genotypes infection in CA group is higher than that in HR group,and the double infection or triple heavy infection are the most common infection.

Objective To analyze the epidemic situation on schistosomiasis in five years after reaching the criteria of transmission control in 1995 in Dali City. . Methods. Epidemiological data of schistosomiasis during 1995-2000 were collected and analyzed. . Results . Stool positive rate in the population was increasing yearly, new cases of infection including cases under 14 years old were detected each year. Acute infection occurred during 1996-1998 consecutively. Stool positive rate in cattle was unstable. Snail-ridden area increased significantly in 1996 and spots with infected snails stayed at a higher level during 1997-2000. . Conclusion . Schistosomiasis in Dali city has been re-emerging though it was once deemed under transmission control. Possible reasons include a low drug-taking rate though distributed, frequent movement of cattle population, and less activity on snail control.

Objective To construct a large animal model of ischemic heart disease induced by acute myocardial infarction (AMI) . Methods Male Diannan Mini-pigs were selected (n=8), weight 20 ± 4 Kg. After general anesthesia and endotracheal intubation, blood pressure and electrocardiograph were monitored. Parasternal incision was taken and thoracotomyv was performed at 4th-to-5th intercostalgap. Pericardium was opened and left anterior descending artery was ligated. Echocardiography was performed at baseline, postoperative 28 and 60 day. Euthanasia and heart explanted was conducted at 60 day of experimental pig. After gross examination of the heart, the histological examination was used to assess myocardial infarction by using H&E staining. Results All of the pigs were presented with ventricular arrhythmias in varying degrees after ligation of the left anterior descending artery, of whom 2 died of refractory ventricular fibrillation, the mortality was 25%. Echocardiography assessment showed the loss left ventricular function, the thinning of left ventricular apical and the enlargement of left ventricule. Histological examination revealed that myocardial fibrosis and fibrous scar were formed in myocardial infarction area. Conclusion The ligation of left anterior descending artery through thoracotomy under direct vision is a reliable strategy for construction of AMI porcine model and the experimental porcine can develop ischemic cardiac dysfunction progressively.

Objective To establish the theoretical basis of the probiotic application among very low birth weight(VLBW) infants,the efficacy of probiotics on the gut microbiota of VLBW infants on the 14th postnatal day was studied.Method The VLBW infants admitted to BaoAn Maternal and Child Care Hospital from January 2015 to December 2015 were randomly assigned into probiotics group and placebo group.From the first feeding to corrected gestational age of 36 weeks,probiotics group was treated with a combination of Bifidobacterium and Lactobacillus while placebo group with placebo.Fecal samples were collected on the 1st and 14th postnatal day.Total bacterial DNA was extracted and sequenced using high-throughput 16S rRNA gene sequencing on MiSeq sequencing platform.Result A total of 21 VLBW infants were enrolled,9 in probiotics group and other 12 placebo group.No significant differences of clinical data existed between the two group (P ＞ 0.05),The abundance and diversity of microflora (P ＞ 0.05) on the first day between the two group were similar.Compared with placebo group,the relative abundance of Bifidobacterium and Lactobacillales in stool samples on the 14th day was significantly increased,while the Halomonas was significantly decreased.The relative abundance of the Shannon-index was increased,but without significant difference (P =0.16).Conclusion Enteral supplementation of probiotics in VLBW infants may increase probiotic bacterium and microflora diversity.

Objective To investigate the relationship between serum homocysteine ( Hcy ) and cognitive impairment in patients with cerebral infarction combined chronic obstructive pulmonary disease (COPD) after stroke, and observe the plasma Hcy levels and cognitive function improvement when treated with folic acid and vitamin B12 .Methods 87 acute cerebral infarction combined with COPD patients as the research object, then the general clinical data were recorded, hematology indexes ( Hcy, folic acid, vitamin B12 ) were determined, and their cognitive function with a simple mental state scale (MMSE) was assayed.According to the plasma Hcy levels, the subjects were divided into Hcy-normal group (n =21) and Hcy-increased group (n=66), then compare the cognitive function between the two groups.Hcy-increased subjects were randomly divided into intervention group (conventional treatment +folic acid 2.5 mg +VitB12 0.5 mg) and control group (conventional treatment).After six months follow-up, we retested plasma Hcy levels and MMSE assessment, comparison of plasma Hcy concentration change and cognitive function improvement between two groups.Results Compared with Hcy-normal group, plasma folic acid, VitB12 levels significantly decreased in Hcy-increased group (P<0.05).And Hcy concentration was negatively correlated with folic acid(r=-0.351,P =0.000)and VitB12(r=-0.242,P=0.015)levels.In addition, the MMSE, directional force and delayed recall score decreased in Hcy-increased group compared with the Hcy-normal group ( P<0.05 ).Hcy levels were significantly lower than the baseline level (P<0.05), MMSE and the sub-project of cognitive function score increased after treated with folic acid and VitB12 for six months, although there was no statistically significant difference.Conclusion Plasma Hcy level is associated with cognitive impairment in patients with cerebral infarction combined chronic obstructive pulmonary disease (COPD), patients treated with folic acid and VitB12 may help slow the recent cognitive dysfunction after stroke in the near future.

BACKGROUND:Total knee replacement is the main treatment for the end of the knee joint disease. How to choose prosthesis replacement according to the different situations of the patient is one of the focuses in the field of joint surgery.
OBJECTIVE: To evaluate middle or short term effects of rotating high-flexion prosthesis for the middle-aged patients with osteoarthritis of knee in total knee replacement.
METHODS: We retrospectively analyzed 48 osteoarthritis patients (55 knees) undergoing total knee replacement with rotating high-flexion prosthesis in the Liuzhou People’s Hospital from January 2009 to January 2013.
RESULTS AND CONCLUSION:(1) Forty-eight patients were folowed up for 23-42 months, mean (24±2.7) months. (2) Knee range of motion and Hospital for Special Surgery knee score were significantly increased after implantation. The excelent and good rate of Hospital for Special Surgery knee score was 85.4%. (3) No infection, loosening or dislocation occurred in al patients. (4) These findings suggest that curative effect of rotating high-flexion prosthesis is definite. After implantation, the range of motion was high, which was accorded with movement pattern of the human body. Prosthesis has a long life, and its repair rate is low. It is an ideal method for the middle-aged patients who want to perform high-flexion activities.
