Pooled literatures showed that the induced abortion in China faces many problems:the number of induced abortion remains large; most cases are young and nulliparity women; the frequency of abortion is high; and the interval between one and another abortion is short. Health promotion strategies should be applied to address these problems. It is important to increase the population's awareness of contraception,especially among nulliparity and migrant populations. Routine and effective contraceptive methods should be recommended and emphasized during induced abortion and delivery to lower the rate of induced abortion.

OBJECTIVE To study the drug-resistant diversity of Gram-negative bacilli isolated from inpatients during recent five years.METHODS A total of 1 464 Gram-negative bacilli isolated were detected and retrospectively analyzed from 1999 to 2003.Antimicrobial susceptibility testing was performed using Kirby-Bauer method.RESULTS The resistance of Pseudomonas aeruginosa to piperacillin rised from 17.6% of 1999 to 79.2% of 2003,and that to ciprofloxacin rised from 4.3% of 1999 to 36.0% of 2003.The resistance of Escherichia coli to quinolones was above 50%,while to third-generation cephalosporins was 30-40%;the resistance of E.coli to piperacillin rised from 42.9% of 1999 to 68.9% of 2003,and that to ciprofloxacin rised from 40.0% of 1999 to 73.5% of 2003.The resistance of Acinetobacter to piperacillin rised from 31.2% of 1999 to 67.5% of 2003,and that to ceftriaxone rised from 36.0% of 1999 to 74.1% of 2003.The resistance of Serratia to ceftazidime,ceftriaxone,gentamicin,amikacin and piperacillin rised sharply.Imipenem was the most active antibiotic tested against Gram-negative bacilli.Cefoperazone/sulbactam and piperacillin/tazobactam also showed excellent activity against Gram-negative bacilli.CONCLUSIONS During recent five years,the resistance of the most common Gram-negative bacilli has increased rapidly.How to delay the resistance development of common strains become a global problem.

Objective: To investigate the factors associated with the patient's adherence to screening in the five years before the diagnosis of hepatocellular carcinoma (HCC) related to chronic hepatitis B ( CHB ), so as to provide reference for improving the screening rate. Methods: From June 2016 to April 2018, the patients with newly diagnosed HCC and a history of CHB for more than five years in Southwest Hospital in Chongqing were interviewed. The information about socio-demographic characteristics, health status, medical care and HCC screening in the past five years were collected. A multivariate logistic regression model was used to analyze the factors associated with adherence to screening. Results: Among 420 participants, 140 ( 33.33% ) adhered to HCC screening, 124 ( 29.53% ) had irregular/incomplete screening, while 156 ( 37.14% ) never had screening. The proportion of early-stage HCC at diagnosis was significantly higher in patients who adhered to screening ( 77.14% ) than that in patients who had irregular/incomplete screening (35.48%) or no screening ( 12.82% ) and the differences were statistically significant ( P<0.05 ). The multivariate analysis demonstrated that five factors were significantly associated with patient's adherence to screening, including education level of high school and above ( OR=2.346, 95%CI: 1.370-4.017), family history of HCC ( OR=2.795, 95%CI: 1.457-5.362 ), history of chronic diseases ( OR=3.860, 95%CI: 2.052-7.262), acceptance of antiviral therapy ( OR=17.816, 95%CI: 9.702-32.716 ) and specialized clinic visits ( OR=8.332, 95%CI: 1.588-43.710 ). Conclusions Adherence to screening is conducive to the early detection of HCC, but the screening rate is low in the patients with CHB. Education level, history of HCC, health status and medical status are significantly related to screening adherence.

Objective To evaluate the effect of different types of tube feeding on swallowing function of stroke patients. Methods 60 patients with dysphagia post stroke were divided into observation group and control group with 30 cases in each group. The control group received indwelling nasogastric tube feeding, and the observation group received intermittent nasogastric tube feeding. They were assessed with Kubota Water Swallow Test (WST) and VGF on the 1st day and 30th day after admission. Results The scores of drinking test and VGF were better in the observation group than in the control group (P<0.05) on the 30th day. Conclusion Long-term nasogatric tube feeding is effective on dysphagia in stroke patients.

OBJECTIVETo assess the effectiveness and safety on post-stroke dysphagia in chronic stage treated with magnetic-ball sticking therapy at the auricular points.

METHODSNinety cases of post-apoplexy dysphagia in chronic stage were randomized into an auricular points group and an acupuncture group. In the auricular points group, the magnetic-ball sticking therapy was applied to subcortex (pizhixia, AT4), brainstem (naogan, AT(3,4i)), mouth (kou, CO1), cheek (mianjia, LO(5,6i)), tongue (she, LO2) and throat (yanhou, TG3) on one ear each time, and were changed on the other ear once every 3 days. In the acupucnture group, acupuncture was applied to Feng-chi (GB 20), Yifeng (TE 17), Shanglianquan (Extra), Jinjin (EX-HN 12), Yuye (EX-HN 13), Shuigou (GV 26) and Tongli (TH 5), etc. The needles were retained for 30 min in each treatment. The treatment was gi-yen once a day in the two groups and the treatment of 6 days made one session. There was 1 day at an interval among the sessions. Totally, 3 sessions of treatment were required. The video fluoroscopic swallowing study (VFSS) was performed for 4 kinds of food with different properties and shapes in each patient. The main indices were Rosenbek penetration-aspiration score, oral-retaining score and throat-retaining score. The efficacy, and the incidences of aspiration pneumonia and malnutrition were compared between the two groups. The nutrition indices were compared before and after treatment between the two groups, such as the skinfold thickness of triceps brachii muscle, serum albumin and peralbumin.

RESULTSIn 21 days of treatment, in the auricular points group, the 1 mL liquid loversol Rosenbek penetration-aspiration score (1.51 +/- 0.69), oral-retaining score (1.17 +/- 0.38) and throat-retaining score (1.30 +/- 0.66) were all lower than those (2.51 +/- 0.67, 1.63 +/- 0.72, 1.67 +/- 0.7) in the acupuncture group separately. The 10 mL liquid loversol Rosenbek penetration-aspiration score (2.27 +/- 0.65), oral-retaining score (1.60 +/- 0.50) and throat-retaining score (1.49 +/- 0.51) were all lower than those (4.19 +/- 0.73, 2.30 +/- 0.51, 2.41 +/- 0.50) in the acupuncture group separately. The 10 mL paste loversol Rosenbek penetration-aspiration score (1.68 +/- 0.81), oral-retaining score (1.11 +/- 0.31) and throat-retaining score (1.10 +/- 0.31) were all lower than those (3.91 +/- 0.68, 1.63 +/- 0.76, 1.60 +/- 0.76) in the acupuncture group separately. The 1/4 cake-form loversol Rosenbek penetration-aspiration score (2.60 +/- 0.65), oral-retaining score (1.40 +/- 0.50) and throat-retaining score (1.74 +/- 0.49) were all lower than those (4.14 +/- 1.10, 2.40 +/- 0.73, 2.30 +/- 0.83) in the acupuncture group separately. The incidence of aspiration pneumonia was 14.9% (7/47) in the auricular points group, which was lower than 55.0% (22/40) in the acupuncture group (P < 0.01). The incidence of malnutrition was 8. 5% (4/47) in the auricular points group, which was lower than 50.0% (20/40) in the acupuncture group (P < 0.01). In 21 days of treatment, the results of the skinfold thickness of triceps brachii muscle and serum albumin in the auricular points group were better than those in the acupuncture group (both P < 0.05).

CONCLUSIONThe magnetic-ball sticking therapy at auricular points achieves the definite efficacy on post-stoke dysphagia in chronic stage and decreases the incidences of aspiration pneumonia and malnutrition. The efficacy of this therapy is better than acupuncture.

Objective To explore the role of glycogen synthase kinase (GSK)-3β/β-catenin signaling pathway on human immunodeficiency virus 1 (HIV-1) negative factor (Nef) protein promoting of human herpesvirus-8 (HHV-8) viral interleukin-6 (vIL-6)-induced angiogenesis.Methods GSK-3β mutant plasmid GSK-3β-S9A,dominant negative (DN) form GSK-3β-DN and the control vector pcDNA3.1+ were transfected into endothelial cells which stably expressed HHV-8 vIL-6 or HIV-1 Nef,or co-expressed vIL-6 and Nef protein.Microtubule formation assay was performed to explore microtubule formation ability.A chick embryo chorioallantoic membrane (CAM) model was used to detect angiogenesis.The expression of GSK-3β/β-catenin signaling pathway-related kinases in transfected cells and CAM tissue were further detected by Western blot.The measurement data were compared by t test.Results The activity of GSK-3β was decreased and the ability of HIV-1 Nef protein was enhanced by transfection with GSK-3β-DN in promoting vIL-6 induced microtubule formation (3.42 vs 2.51,t =3.67,P＜0.01) and angiogenesis (6.25 vs 3.97,t=4.06,P＜0.01).In contrast,the activity of GSK-3β was significantly increased and these functions of HIV-1 Nef protein mentioned above were inhibited by transfection with GSK-3β-S9A (0.62 vs2.51,t=8.48,P＜0.01; 0.39 vs 3.97,t=8.59,P＜0.01).The results of Western blot showed that with the elevated level of,β-catenin (in cells:3.53 vs 2.07,t=6.60,P＜0.05; in tissues:2.76 vs 1.74,t=17.40,P＜0.01) and vascular endothelial growth factor (VEGF,in cells:2.68 vs 1.87,t=4.28,P＜0.01; in tissues:2.20 vs 1.39,t=7.08,P＜0.01) were increased in the GSK-3β-DN transfected cells or tissues,while the opposite results were achieved in the GSK-3β-S9A-transfected cells (GSK-3β phosphorylation:0.50 vs 1.47,t=7.33,P＜0.01; β-catenin:1.05 vs 2.62,t=29.50,P＜0.01; VEGF:0.74 vs 2.16,t=20.95,P＜0.01) or tissues (GSK-3β phosphorylation:0.35 vs 1.97,t=10.72,P＜0.01; β-catenin:0.79 vs 1.77,t=5.72,P＜0.01; VEGF:0.43 vs 1.65,t=11.89,P＜ 0.01).Conclusion GSK-3β/β-catenin signaling pathway is involved in vIL-6-induced angiogenesis promoted by HIV-1 Nef protein,which would be valuable for the therapy of Kaposi's sarcoma,an acquired immunodeficiency syndrome,as a potential molecular target.

Objective To explore the clinical and pathologic characteristic of deep fungus infection under mechanical ventilation in neonate. Method The clinical datas of 18 neonates under mechanical ventilation approved with deep fungus infection by autopsy from 1985 to 2003 in our department were collected and analyzed.Results In 18 infants who survived deep fungus infection,2 cases were premature and 16 cases were mature,the birth weight and the numbers of patients were:2500 g 2 cases;Time under mechanical ventilation was 8-86 days and the average time under mechanical ventilation was 13 days. The pathogen caused deep fungus infection was Aspergillus(8/18),Candida albicans(6/18) and Mucor(4/18),respectively. The infected organ were lung(12/18),brain(2/18),liver(4/18) and gastrointestinal tract(2/18),respectively.Two of them were found been infected in lung and liver at the same time.Conclusions We must attach importance to deep fungus infection in neonate under machine ventilation.Aspergillus and Candida albicans were the main pathogen bacteria and lung was the main infected organ of neonatal deep fungus infection.Early diagnosis may be the efficiency approach to increase livability.
