Objective To study the detection and significance of human papillomaviral DNA(HPV-DNA) in cervical disease. Methods The express of HPV-DNA were detected by hybrid capture 2 in the patients with chronic cervicitis ( n = 166), cervical intraepithelial neolasia ( GIN ) ( n = 89 ) and uterine cervix cancer ( UCC ) ( n = 23 ). Results The positive expression rate of HPV-DNA in GIN Ⅰ , Ⅱ , Ⅲ grade and UCC were 70.8% (17/24) ,79. 3% (23/29) ,88.9% (32/36) ,91. 3% (21/23). They were significantly higher than those in chronic cervicitis 30.7% (51/166) (P ＜ 0. 01 );As the development of cervical disease, HPV-DNA positive expression had increasing trend.Conclusion The detection of HPV-DNA had an important role for the early UCC screening,prevention and treatment.

The purpose of this study was to observe whether HBV can infect HSC in vitro. LX-2 cells, the human activated HSC cell line, were incubated with human serum containing HBVDNA at final concen-trations from 0.01 to 10 copies/cell and harvested after 24,48 and 72 hours. Hepatitis B surface antigen (HBsAg) and hepatitis B core antigen(HBcAg) were detected by lmmunohistochemistry dyed by DAB. By Immunohistochemistry, no positive particles in LX-2 cells, a few of dark brown particles (HBsAg and HB-cAg) were found in cytoplasm and nucleoli of HepG2.2. 15 cells,a lot of clark brown particles were found in liver biopsies of patients with chronic hepatitis B. In vitro, there was no evidence that HBV can infect and express antigens in LX-2 cells.

Objective:To observe the curative effect of modified amniotic membrane transplantation for agricultural pterygium.Methods: A total of 276 cases (276 eyes) with early pterygium were randomized divided into traditional group (138 cases) and modified group (138 cases) as random table. The traditional group was treated with pterygium excision in combination with autologous conjunctival transplantation; the modified group was treated with modified amniotic membrane transplantation; to observe the curative effect of the two groups.Results: After all of patients were followed up for 1 year, 122 cases were cured and 16 cases were recurrence, and the recovery rate was 88.41% in traditional group; 131 cases were cured and only 7 cases were recurrence, and the recovery rate was 94.93% in modified group and was better than traditional group; the difference between the two groups was statistical significant (x2=5.02,P<0.05).Conclusion: The modified amniotic membrane transplantation method is simple in operation, mini invasive for eye tissue, and can retain conjunctival tissue in utmost; it also can improve success rate of surgery and be an effective mean for treatment of pterygium.

Objective To explore the clinical manifestations,diagnosis,misdiagnosis and treatment of primary hyperparathyroidism.Methods The clinical data of 36 patients with primary hyperparathyroidism admitted into the First Affiliated Hospital of Chongqing Medical University from January 2009 to October 2014 were reviewed and analyzed retrospectively.Results The manifestations of primary hyperparathyroidism were various and atypical.Primary hyperparathyroidism was often misdiagnosed as other diseases by 25.0％ (9/36).Among the patients,the ratio of male to female was 1:1,and median age was 58 years old.Of all patients,there were 9 persons with joint pain,digestive system symptoms in 7 cases,cervical mass discovered in 6 cases(3 cases were found when B ultrasonic examination),urinary calculus in 5 cases,fatigue symptoms in 4 cases,osteoporosis and urinary calculus in 2 cases,1 case with fracture,2 cases without any symptoms.Their calcium and parathyroid hormone level were increased by various degree.The accuracy rates of level diagnosis of Color Doppler ultrasound combine with CT or 99Tcm-MIBI were improved obviously,85.2％ and 93.1％ respectively.Twenty-eight patients received surgical treatment and pathology examination confirmed the accurate pathological types after surgery.There were 23 cases of parathyroid adenoma,1 case parathyroid hyperplasia,1 case parathyroid carcinoma,2 cases of parathyroid adenoma with nodular goiter,parathyroid adenoma merged thyroid carcinoma in 1 case.Serum calcium and parathyroid hormone level declined obviously after operation.The other 8 patients received non-surgical treatment,7 cases were alleviated and 1 case died due to irreformable high blood calcium crisis.Conclusion There should be pay attention to recognize primary hyperparathyroidism,check the blood calcium,and about suspected cases should be performed as early as parathyroid tested,neck color Doppler ultrasound.Early surgical treatment can significantly improve the prognosis and quality of life.

Objective To investigate the distribution and drug resistance of clinical bacteria infection in the Second Affiliated Hospital of Kunming Medical University,so as to provide reference for the treatment of bacterial infections.Methods 4 802 strains of bacteria isolated from this hospital,from January 2013 to December 2013,were retrospectively analysed.The isolates were identi-fied by using VITEK-2 Compact bacterial identification system.Drug resistance was measured by using disc diffusion test,and its results were interpreted according to the breakpoints of Clinical and Laboratory Standards Institute(CLSI)2013.WHONET 5.6 was applied for analysis.Results These pathogens were mainly isolated from urine,sputum,blood,secretions and pus,accounted for 31.7%,21.4%,1 9.7%,1 1.7% and 7.0%,respectively.In the clinical isolates,gram negative bacilli accounted for 55.8%, which was mainly Escherichia coli(26.3%).Gram positive cocci accounted for 31.7%,,which was mainly coagulase negative staph-ylococcus(1 5.0%).Fungi accounted for 3.1%,which was mainly Candida albicans.Escherichia coli and Klebsiella pneumonia were most sensitive to carbapenem,resistance rate was less than 10.0%.The detection rates of Escherichia coli and Klebsiella pneumoni-ae producing extended-spectrumβ-lactamases(ESBLs)was 61.1% and 49.1%,respectively.Among non-fermentative gram nega-tive bacilli,excepting Pseudomonas aeruginosa had good sensitivity to Amikacin,Pseudomonas aeruginosa and Acinetobacter bau-mannii showed high resistance to most antibiotics(resistance rate was more than 50.0%).Among gram positive bacteria,the detec-tion rates of meticillin-resistant Staphylococcus aureus and methicillin-resistant coagulase negative Staphylococcus were 42.3% and 65.6%,respectively.The resistance rates of Enterococcus faecium to most of antibacterials were higher.Except for linezolid and teicoplanin,the resistances of Enterococcus faecium to other antibacterials were higher than those of Enterococcus faecalis.Only a strain of Enterococcus faecium resistant to vancomycin was isolated.Conclusion Resistance monitoring might have significance in guiding the clinical rational use of antimicrobial agents,and reducing the spread of antibiotic resistance in bacteria.

OBJECTIVE:To explore the effects of folic acid combined with vitamin B12 on the vascular cognitive impairment (VCI)and homocysteine(Hcy)of patients with hypertension and cerebral stroke. METHODS:80 VCI patients with hypertension and cerebral stroke were regarded as observation group,and another 20 healthy volunteers were regarded as healthy control group. Observation group was treated with enhanced homogenized meal 300-500 ml,3 times a day+Folic acid tablet 5 mg,3 times a day+Vitamin B12 tablet 25 μg,3 times a day. Observation groups were treated for continuous 2 months with no nasal administration by themselves. The Mini-Mental State Examination(MMSE)score,the level of folic acid,vitamin B12 and Hcy before and after treat-ment were observed and compared with healthy control group,and the incidence of adverse reactions was recorded. RESULTS:Af-ter treatment,MMSE score,the level of folic acid,vitamin B12 in observation group were significantly higher than before and low-er than healthy control group,the level of Hcy was significantly lower than before and higher than healthy control group,the differ-ences were statistically significant(P<0.05). The incidence of adverse reactions was 5.00%. There were no serious adverse reac-tions. CONCLUSIONS:Folic acid combined with vitamin B12 can reduce the cognitive impairment degree of patients with hyperten-sion,cerebral stroke and vascular cognitive impairment and level of Hcy,with good safety.
