Objective To establish a stable animal model for sequentially dynamic and direct monitoring of the skin wound infection. Methods The mice with full-thickness skin incisions were replicated. After immediate subcutaneous suture,the mice were randomly divided into four groups,ie,Group A was inoculated with 50 μl sterile PBS solution),Groups B,C and D were inoculated with 50 μl suspension containing 1 × 106,1 × 108 and 1 × 1010 colony forming unit (CFU)/ml bioluminescent methicillin-resistant staphylococcus aureus (MRSA) respectively.Then,the diet behavior of each group was observed and the mean weight and mortality of each group were also recorded at different time points.The bioluminescent intensity of fluoresce in the wounds was recorded at different time points by using the charge-coupled device (CCD) based imaging system.Local wound tissues were incised at 24 hours after inoculation for HE staining so as to observe wound inflammatory reaction in each group.Wound healing time of each group was also recorded. Results ( 1 ) Average weight:Groups A and B showed unobvious changes in weight; Group C lightened until day 3 after inoculation and then recovered gradually to the preinoculation level at day 14; Group D lightened gradually until death.(2)Mortality:Groups A and B had no death; Group C had 10％ deaths at day 14; Group D had 100％ deaths.(3) Bioluminescent intensity of wounds:Groups A and B showed a gradual weakened luminescence since the day of inoculation and had almost complete disappearance at days 5 and 7 respectively; there was no sign of obvious increase or decrease in Group C from the day of inoculation till day 14 ; Group D had a gradual increase since the day of inoculation and the luminous area expanded until the death.(4) HE staining at 24 hours after inoculation:all the four groups showed inflammatory cell infiltration,especially in Groups C and D.(5) Wound healing time:wound healed at days 5 and 7 after inoculation in Groups A and B; the wounds showed no healing even at day 14 in the Group C,but the wounds length and area did not show obvious enlargement or diminishment ; the wounds extended gradually until the death in the Group D,since the day of inoculation. Conclusions The inoculation of 50 μl suspension with 1 × 108 CFU/ml bioluminescent MRSA to full-thickness skin incision rats allows direct,real-time dynamic and continuous detection of the occurrence and development of the wound infections.The infection model is easy to make and has stability and high repeatability.

Objective:Taking Chongyang county of Hubei Province as an example, the paper describes the in-tegration of the maternal and child health ( MCH) and family planning ( FP) service system and analyses the key ele-ments to provide reference for promoting integration. Methods: qualitative interviews and quantitative questionnaire were used to collect data. The software QSR Nvivo 8. 0 and SPSS 17. 0 were used for qualitative and quantitative data analysis. Results:Based on the correct understanding of integration, Chongyang implements the supporting policies actively, maintains the original compensation mode unchanged, follows the principle of“no reducing headcounts and no downsizing” strictly, promotes the merger of institutions rapidly, adjusts the service contents and methods reasona-bly, and integrates the maternal and child and family planning information platform. Conclusion:The correct concept of integration, appropriate staffing, and stable funding in Chongyang provide rich experiences for future research. However, there is room for improvement in staffing, incentive mechanisms, service content, and forms.

Objective To study the sonographic features of mammary sclerosing adenosis (SA) and evaluate the diagnositic value of ultrasound. Methods Thirty-ifve patients with pathologically conifrmed SA in Ruijin Hospital from May 2009 to August 2013 were retrospectively analyzed. The Breast Imaging Reporting and Data System (BI-RADS) lexicon was introduced to describe the lesions. The diagnostic sensitivity was analyzed. Results The main sonographic ifndings of SA could be characterized into three types:(1) malignancy-looking nodule type (typeⅠ) (34%, 12/35). (2) benignity-looking nodule type (typeⅡ) (43%, 5/35). (3) architectural disorder type (typeⅢ) (23%, 8/35). Lack of blood supply has the greatest value in differential diagnosis among all sonographic features. The diagnositic sensitivity in typeⅠ, typeⅡ, typeⅢwere 0 (0/12), 93%(14/15), and 75%(6/8) respectively. The general sensitivity was only 57%(20/35). Conclusions There are no typical sonographic features in mammary sclerosing adenosis. Ultrasound doctors should improve their knowledge about this disease.

Objective:To study the effects and safety of metformin combined with vildagliptin on the glycemic control for patients with newly diagnosed type 2 diabetes mellitus.Methods:60 patients with type 2 diabetes mellitus who were treated from February 2015 to April 2016 were selected and divided into the control group and the observation group according to different treatment methods.The control group was treated with routine treatment.The observation group was treated with vildagliptin based on the control group.The blood glucose,glycosylated hemoglobin,two-hour postprandial blood glucose and serum as well as urinal amylase were measured before and after treatment,and the clinical curative effect of the two groups and the levels of interleukin-6,tumor necrosis factor and C-reactive protein were compared.Results:After treatment,the total effective rate of observation group was 90％,which was significantly higher than that of the control group(66.7％,P＜0.05).After treatment,the serum interleukin-6,tumor necrosis factor,C-reactive protein and fasting blood glucose,glycosylated hemoglobin and postprandial blood glucose levels were significantly lower than those of the control group[(7.63± 1.12)dvs(8.68± 1.30)d;(7.23± 0.95)d vs(7.89± 1.20)d;(11.14± 1.56)d vs(12.12± 1.89)d];[(12.12± 1.89)d vs(ll.20± 1.34)d;(6.89± 0.96)d vs(8.23± 1.10)d;(1.65± 0.23)d vs(3.65± 0.48)d] (P＜0.05).After treatment,the INS level of observation group was significantly lower than that of the control group (P＜0.05) and the GLP-1 level was significantly higher than that of the control group (P＜0.05).Conclusion:Metformin combined with vildagliptin could effectively control the blood glucose of patients with newly diagnosed type 2 diabetes and enhance the safety.

Objective:To observe the effect of abdominal electroacupuncture(EA)on intestinal function in patients with constipation after stroke. Methods:A total of 100 patients with post-stroke constipation were divided into an observation group and a control group by the random number table method,with 50 cases in each group.The control group was treated with oral lactulose,10 mL each time,3 times a day,for 2 consecutive weeks.The observation group was treated with additional abdominal EA at Tianshu(ST25),Fushe(SP13),and Daheng(SP15)on the basis of oral lactulose,30 min for needle retention each time,once a day,for 2 consecutive weeks.The total effective rate after treatment,constipation symptom score,the score of patient assessment of constipation quality of life scale(PAC-QOL),serum motilin(MTL)level,and the score of mini-mental state examination(MMSE)were compared between the two groups. Results:After 2 weeks of treatment,the total effective rate was 93.5%in the observation group and 76.1%in the control group,and the difference between the two groups was statistically significant(P<0.05).The constipation symptom score,PAC-QOL score,MMSE score,and MTL level changed significantly after treatment in both groups(P<0.05).After treatment,the constipation symptom score and PAC-QOL score in the observation group were lower than those in the control group,while the MMSE score and MLT level were higher than those in the control group,and the differences between the two groups were statistically significant(P<0.05). Conclusion:On the basis of oral lactulose,EA at abdominal points can significantly improve the intestinal and cognitive function of stroke patients simultaneously.

An RP-HPLC method for determination of luteolin from Elsholtzia blanda Benth. extracts in rats' plasma was established and the pharmacokinetics of luteolin in rats was studied. Drug blood samples from caudal vein were gotten after oral administration of luteolin. Plasma samples were determined by RP-HPLC after being deproteinized with trichloroacetic acid and extracted with ethyl acetate. The calibration curve was linear in the range of 0.37-47.27 microg x mL(-1). The limit of quantification was 0.37 microg x mL(-1). The method recovery of luteolin was 93%-99%. The extract recovery was 75%-85%. RSDs of intra-and inter-day precisions were less than 5%. The concentration-time curve of luteolin after oral administration of Elsholtzia blanda Benth. extracts was fitted to two compartment open model. Two factors analysis of variance were adopted in the evaluation of gender and time spots for collection of blood. The result suggested that the gender-based difference in blood-drug concentrations had statistical significance. The metabolite in blood was identified as galcuronide. The method is sensitive, specific, accurate, and is appropriate for determination of luteolin in vivo.

OBJECTIVETo observe the effect of magnesium sulfate, Nifedipine Tablet (NT) combined Salvia Injection (SI) on endothelin-1 (ET-1), nitric oxide (NO), thromboxane A2(TXA2), prostacyclin I2(PG2), and hemorheology of preeclampsia patients.

METHODSTotally 704 preeclampsia patients were randomly assigned to the treatment group and the control group, 352 cases in each group. All patients were treated with magnesium sulfate combined NT (on the first day: slow intravenous injection of magnesium sulfate 5 g + intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg; on the second and third day, intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg), while those in the treatment group were dripped with SI additionally at 20 mL per day for 3 consecutive days. Before and after treatment plasma levels of endothelin-1 (ET-1), nitric oxide (NO), TXA2, PGi2, and hemorheology indicators [such as high blood viscosity (HBV), low blood viscosity (LBV), plasma viscosity (PV), erythrocyte rigidity index (ERI), fibrinogen (FIB)] of two groups were detected.

RESULTSCompared with the same group before treatment, serum levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the two groups after treatment (P <0. 05), but levels of NO and PG2 increased (P <0. 05). Compared with the control group in the same period, levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the treatment group after treatment (P <0. 05), but levels of NO and PGI2 increased (P <0. 05).

CONCLUSIONMagnesium sulfate, NT combined SI could effectively regulate the balance of ET-1/NO and TXA2/PGI2, and improve hemorheology of preeclampsia patients.

Objective To investigate clinical manifestation of unspecified functional bowel disorder (UFBD), the features of coexistence with functional gastrointestinal disorder (FGID) and its relationship with psychological factors and sleep disturbance in the Chinese Army servicemen.Methodsc FGIDs were diagnosed based on the RomeⅢ Modular Questionnaire. The subjects were 189 servicemen with UFBD (UFBD group) and 372 without FGID (control group). All subjects completed symptom checklist 90 (SCL-90) and Pittsburgh Sleep Quality Index (PSQI) questionnaire.Results'Have to rush to the toilet when having a desire to defecate' was the most frequent symptom of UFBD (93.7%). More than one half of UFBD patients had the symptom 'a feeling of incomplete emptying as bowel movements' or 'straining during bowel movements'. Twenty-eight percent of UFBD subjects had combined FGID (namely cFGID). Among them, the most frequent was proctalgia fugax (7.9%), followed by cyclic vomiting syndrome (6.3%), functional fecal incontinence (6.3%), functional dyspepsia (4.8%) and belching (4.8%). The UFBD group scored significantly higher than the control group in the global severity index (GSI) and in all SCL-90 subscales (P<0.05). The scores of the four domains (sleep quality, sleep latency , sleep disturbance and daytime function disorder), total PSQI score and proportion of poor sleeping quality were significantly higher in the UFBD group than in the control group (P<0.05). The subjects scored significantly higher in combined FGID group than in UFBD group in GSI and in all of SCL-90 subscales, except for phobic anxiety subscales (P<0.05). However, there was no significant difference in each domain, total PSQI and proportion of poor sleeping quality between the cFGID group and UFBD group (P>0.05).ConclusionPathogenesis of UFBD may be closely correlated with psychiatric and psychological factors and sleep disturbance. cFGID are associated with an increased severity of psychopathological features.
