Objective To monitor the resistance of Streptococcus pneumoniae following the 2004 in Qingdao area, and to provide a reasonable basis for clinical application of antimicrobial agents. Methods Collecting respiratory tract, blood, cerebrospinal fluid and other specimens from out-patient and in-patients of some hospital in Qingdao from January 2005 to December 2008. According to the recommendation of NCCLS, antibiotic resistance analysis of 11 kinds of antibiotic to the isolated 231 Streptococcus pneumoniae by micro-agar dilution method, and analysis resistance trends and age differences. Results The results showed that the rate of Streptococcus pneumoniae not sensitive to penicillin is 23. 38% (PRSP: 9.52% , PISP: 13. 85% ) , resistant to cefotaxime is 9. 96% (23/231), resistant to amoxicillin is 12. 55% , resistant to erythromycin is 90. 48% (209/231). PRSP rate of patients younger than 14 years of age 27. 91% (12/43), significantly higher than that of the PRSP rate of adults 5. 38% (10/186). Conclusion The rate of resistant to penicillin Streptococcus pneumoniae increased significantly from 2004, and an increasing trend year by year, the resistance of Streptococcus pneumoniae is also a rising trend year by year. For patients infected low penicillin-resistant Streptococcus pneumoniae in this region, cefotaxime, amoxicillin are preferred drugs.

Objective To study wether dezocine (DZ) can attenuate neuropathic pain in rats and to investigate its mechanism.Methods Neuropathic pain was induced by tight ligation of the left L5 spinal nerve of the male SD rats. 24 Spinal nerve ligation (SNL) model rats were randomly divided into three groups:the first group (saline group, n=8), rats were given intraperitoneal injection of 1ml of saline 14 days after SNL surgery; the second group (dezocine group, n=8), rats were given intraperitoneal injection of 5mg/kg of dezocine in 1ml saline 14 days after SNL surgery;the third group (morphine group,n=8),rats were given intraperitoneal injection of 5 mg/kg of morphine 14 days after SNL surgery. Results Intraperitoneal injection dezocine and morphine had significant analgesic effect in neuropathic pain rats. This analgesic effect lasted for 4-6 hours.Continuous injection of morphine for 3 days produced significant tolerance, while continuous injection of dezocine for 7 days still had significant analgesic effect on neuropathic pain. Conclusion Intraperitoneal injection of dezocine and morphine can attenuate SNL neuropathic pain, continuous injection of morphine for 3 days can produce significant tolerance, while continuous injection of dezocine for 7 days still has significant analgesic effect on neuropathic pain.

Objective:To evaluate the effect of remote lifestyle intervention on the management of weight and related indicators in the overweight and obese population.Methods:A total of 400 individuals with overweight or obesity who participated in remote lifestyle intervention in the Health Management Department of Shenzhen People′s Hospital from May 2015 to December 2018 were included as the remote intervention group, and 400 individuals with overweight and obesity who matched their age and gender were selected as the control group. Dietician established individual WeChat groups with the remote intervention group, and the WeChat platform was used to conduct remote lifestyle intervention for them, including setting weight control goals, giving timely feedback to the food log based on photos, providing exercise guidance and psychological support. The control group received personalized diet and exercise prescriptions, but did not receive remote intervention. After adjusting the data by propensity score matching method, univariate and multivariate logistic regression models were used to analyze the management effect of weight and related indicators in the two groups after one year.Results:After one year of intervention, effective data were obtained from a total of 755 cases (371 cases in the remote intervention group and 384 cases in the control group), and effective data were retained from 446 cases (223 cases in the remote intervention group and 223 cases in the control group) after bias matching. The body mass index (BMI), systolic blood pressure, fasting blood glucose, triglyceride, total cholesterol, low-density lipoprotein, and serum uric acid of the remote intervention group [(24.85±2.52) kg/m 2, (110.21±10.53) mmHg, (4.96±0.65) mmol/L, (1.25±0.82) mmol/L, (4.87±1.11) mmol/L, (2.88±0.74) mmol/L, and (306.01±95.66) mmol/L respectively] were significantly lower than that of the control group [(27.76±2.28) kg/m 2, (121.14±14.07) mmHg, (5.10±0.87) mmol/L, (1.54±0.83) mmol/L, (5.28±0.96) mmol/L, (3.13±0.80) mmol/L, (355.16±92.68) mmol/L respectively] (all P<0.05). After intervention, intervention was consistently being influencing factors when BMI was reduced by 4%―12%, ( P<0.05). The probability of a 12% reduction in BMI in the remote intervention group was 112.486 times higher than that in the control group (95% CI: 16.852-890.266). At the same time, the initial BMI was an influential factor for the restoration of normal BMI. For every 1 kg/m 2 decrease in the initial BMI, the probability of restoration of normal BMI was 4.76 times higher than that before the decrease (95% CI: 3.222-5.057). Conclusions:Remote lifestyle intervention has a certain effect on the management of weight and related indicators in the overweight and obese populations. It has significant effect on weight loss of overweight and mildly obese people, but has limited effect on moderate and severe obese people.

Objective To investigate the expression of Vacuolar-H +-ATPase (V-ATPase) and P-glyeoprotein (P-gp) protein in colon carcinoma tissues,the correlation between the expression of V-ATPase and P-gp and their clinicopathological significance.Methods In samples from 80 cases of colon cancer,20 cases of colon adenoma and 10 cases of normal colonic mucosa tissues,the expression of V-ATPase and P-gp protein were detected by immunohistochemical method,their relationship was analyzed,the clinicopathological features and prognosis were evaluated.Results In colon cancer,V-ATPase and P-gp protein expression was 72％ and 80％,higher than that in colon adenomas (40％,35％),and in normal colon mucosa (20％,20％),the difference was statistically significant (P ＜ 0.05).There was a positive correlation between the expression of V-ATPase and that of P-gp (r =0.567,P ＜0.01).V-ATPase and P-gp protein expression in colon cancer was associated with TNM stage,lymph node metastasis and tumor differentiation (P ＜ 0.05).Patients with high V-ATPase expression had lower 5-year survival rate than those with low V-ATPase expression (P =0.023),and 5-year recurrence rate was higher than those with low expression (P =0.024).Conclusions The expression of V-ATPase is up-regulated in colon cancer,there is a positive correlation with colon cancer progress and metastasis,and high V-ATPase protein expression predicts poor prognosis.

Objective To raise the awareness of adrenal Castleman′s disease by analyzing the clinical features and management of a patient with adrenal Castleman′s disease. Methods A case of adrenal Castleman′s disease of our hospital was retrospectively analyzed, including clinical feature, laboratory findings, pathology, treatment, and follow-up. All the data and pertinent literatures were reviewed and analyzed. Results An incidentaloma measuring 4. 8 cm × 6. 3 cm in the right adrenal gland was observed in a 30-year-old men in a ultrasonography examination performed due to a medical check-up. Laboratory analysis showed that the lesion was not hyperfunctioning. The patient subsequently underwent an exploratory laparotomy. Pathological examination revealed retroperitoneally localized Castleman′s disease of the hyaline vascular type. Conclusion Adrenal Castleman′s disease is a rare cause of lymph node hypertrophy, and it is necessary to keep in mind the possibility of its occurrence and take it into consideration in the differential diagnosis of any solitary, heterogeneous, and hypervascular retroperitoneal mass. The proper cooperation between the clinician and pathologist allows early diagnosis and suitable therapy.

Objective To explore the effects of arsenic exposure on learning and memory and its potential mechanism in rats.Methods Water-based arsenic-exposed rat models were established on 4-l0 postnatal days.The experimental animals were divided into 4 groups (10-12 cases in each group):the control group,the 15 μg/L As2O3 water group,the 30 μg/L As2O3 water group,and the 45 μg/L As2O3 water group.Cognitive functions were examined with the Morris water maze,exploratory behavior was detected by the exploratory behavior test.The hippocampus of pups from each experimental group was sectioned at various time points after arsenic exposure.The morphologies and neurogenesis of the neurons in the hippocampus CA1-CA3 region and dentate gyrus (DG) were observed by hematoxylin-eosin staining,Nissl staining,and doublecortin (DCX) immunostaining at different time points after arsenic exposure.Results Compared with the normal control group,the escape latency of the rats in the arsenic-exposed group was prolonged.The average escape latency of the rats in the normal control group,15 μg/L As2O3 group,30 μg/L As2O3 group and45 μg/L As2O3 group were (17.00±9.53) s,(35.89 ±19.81) s,(26.60 ±18.84) s,and (33.79 ±18.08) s,respectively,and the difference among 4 groups was statistically significant (F =3.591,P ＜ 0.05),and the residence time in the original target quadrant was shortened,respectively,(38.93 ± 8.33) s,(36.03 ± 16.25) s,(29.85 ± 9.27) s,and (29.84 ± 10.16) s,respectively,and there was no significant difference among 4 groups (F =1.681,P =0.187).HE staining and Nissl staining showed that pathological changes such as edema,degeneration and necrosis were observed in the hippocampal CA1 area and CA2 area as well as dentate gyrus cells in rats exposed to arsenic in the acute phase.The higher the concentration of arsenic exposure,the more obvious the cell structure disorder was.However,5 weeks after exposure,the pathological changes in hippocampal neurons in the arsenic-exposed group gradually returned to normal.Immunohistochemistry showed that the expressions of DCX in the CA1,CA2 and dentate gyrus of rats exposed to arsenic decreased significantly 24 h after arsenic exposure,especially in the 45 μg/L group.Five weeks after arsenic exposure,there was no expression in the hippocampal CA1-CA3 area,and there was still a small amount of expression in the dentate gyrus.Conclusions Postnatal low-concentration arsenic exposure may impair learning and abnormal germination of neurons in the hippocampal dentate gyrus may be the underlying mechanism.

Objective To investigate the effect of omeprazole combined with FOLFOX scheme as an adjuvant therapy for stage Ⅱ or Ⅲ colon cancer patients after a radical resection.Methods 98 stage Ⅱ or Ⅲ colon cancer patients in our hospital from January 2008 to December 2009 were randomly divided into study group (48 cases) receiving regimen of omeprazole combined with FOLFOX and control group (50 cases) treated with FOLFOX chemotherapy after radical colectomy.Surgical specimens were examined for expression of V-ATPase protein.Chemotherapy period was 6 months,8-12 courses.We observed results of follow-up curative effect,comparing the side effects and postoperative 2 year,3 year and 5 year disease-free survival rate (DFS) difference using statistical analysis.Results Study was completed in all 93 cases,5 cases were lost to follow-up.The baseline data distribution in the two groups were balanced basically.In study group the gastrointestinal side effects of chemotherapy was lower than the control group (x2 =4.924 6,P =0.026).In the two groups,the 2-year,3-year and 5-year DFS were 73％ vs 60％ (x2 =1.743 7,P =0.187),62％ vs50％ (x2 =1.4075,P=0.235),49％ vs40％ (x2 =0.8159,P=0.366) (P＞0.05).V-ATPase protein expression was 71％ (70/98) in all samples.The 2-year and 3-year DFS of patients for V-ATPase protein positive expression in the two groups were 75％ vs 51％ (x2 =3.970 8,P =0.046),66％ vs 40％ (x2 =4.399 5,P =0.036).Compared with the control group,the 2-year,3-year DFS increased in the study group (P ＜ 0.05).In stage Ⅲ colon cancer patients,the 2-year DFS was 73％ vs 47％ (x2 =4.504 5,P =0.034).Conclusions PPI combined with FOLFOX in V-ATPase protein positive expression or Ⅲ stage colon cancer patients after radical colectemy improves long-term survival,as well as reduces the gastrointestinal side effects of chemotherapy.
