OBJECTIVE To observe the situation of Mycoplasma and Chlamydia trachomatis(Ct) infection in the patients with reproductive tract infection(RTI),and their antibiotic resistance analysis and therapeutic strategies.METHODS To analyze Ct antibody with monoclonal antibody immunogold filtration assay,and to detect Mycoplasma and their drug sensitivity with culture method.RESULTS From 581 specimens there were 42 cases who had Ct(7.2%),and 239 cases who had Mycoplasma(41.1%).The single infection of Ureaplasma urealyticum(Uu) was in 165 cases(28.4%) and of Mycoplasma hominis(Mh) in 18 cases(3.1%),respectively,Uu+Mh were in 39 cases(6.7%).Uu+Ct were in 17 cases(2.9%).The result of drug sensitivity showed that the drug resistance of Uu to erythromycin was 64.8%,to roxithromgcin was 62.6%.Mh was also with the similar tendency.The mixed infections rate was elevated.Doxycycline,minocycline,and josamycin had the higher bacteriostatic ability.CONCLUSIONS With the growing number of mycoplasma infections,and large-scale application of antibiotics themultidrug-resistance was occurred,so it is important to clinical reference to the selection of antibiotic susceptibility test results,and sufficient and adequate course of therapy to reduce the selection of resistant strains.Experimental evidence showed doxycycline,minocycline and josamycin can be used as the first choice for clinical medicine in mycoplasma infection.

Objective To evaluate the relationship between the number of copies of genes and congenital diaphragmatic hernia by the detection of multiple loci in infants with congenital diaphragmatic hernia. Methods Multiple loci were analyzed by Microarray analysis of Affymetrix Cytoscan 750 k in 11 neonates with congenital diaphragmatic hernia, in whom 1 case was twins,and his fraternal twins were diagnosed of fetuse intestinal dilatation. Results A homozygous deletion (8 p11.22 arr[hg19]) was found in one neonate with congenital diaphragmatic hernia, and was eventually confirmed that the depolymerization of the biotin and metalloprotease (ADAM) 3A genes lead to homozygous deletion of the 1～15 exon. Conclusion The alteration of ADAM3A copy number may be the cause of congenital diaphragmatic hernia.

Objective To investigate gene expressions of matrix metalloprotease (MMP-2, MMP-9) and tissue inhibitor of metalloproteinase-2 (TIMP-2) and RECK ( reversion inducing cysteine-rich protein with Kazal motifs) in the liver tissue of rats with Vibrio vulnificus sepsis. Methods Vibrio vulnificus sepsis model was induced by injection of 1 mL/100 g Vibrio vulnificus (9 × 106 cfu/mL) at hind limbs in 50 Sprague-Dawley male rats of clean grade, each time 10 animals were sacrificed at 2, 6, 9, 12 and 16 h after injection and liver samples were taken. Ten rats served as control group. The ethological changes were observed. The total RNA was extracted from liver tissue and the gene expressions of MMP-2, MMP-9, TIMP-2 and RECK were evaluated by semi-quantitative RT-PCR. Results The rats manifested shortness of breath, fever and swelling in hind limbs at 4 h after injection of Vibrio vulnificus. These symptoms gradually deteriorated, and the rats presented cyanosis and convulsion at 12 h. The gene expressions of MMP-2 and MMP-9 were markedly up-regulated, while those of TIMP-2 and RECK were down-regulated. Conclusion The study suggests that the elevation of MMP-2 and MMP-9 and down-regulation of TIMP-2 and RECK is associated with the development of Vibrio vulnificus sepsis.

Objective To investigate the clinical safety and efficacy of mechanical thrombectomy(MT) with Solitaire stent compared with the selective intra-arterial thrombolysis (IAT) in the treatment of acute cerebral infarction.Methods Totally 82 cases patients with severe acute ischemic stroke caused by middle cerebral artery stenosis from January 2014 to May 2016 in the stroke treatment center of the first people's Hospital in ZunYi city who were applied with the mechanical thrombectomy or the selective intra-arterial thrombolysis was included,and a comparative analysis was conducted on the mTICI rating to assess the interventional recanalization,the NIHSS score after the treatment,bleeding rate,and conditions of neurological functional recovery 90 days after operation.Results There were 42 cases applied with the mechanical thrombectomy (MT group),40 cases applied with the intra-arterial thrombolysis (IAT group).The total effective rate reached 85.70％ in the MT group and 62.50％ in the IAT group,the difference was significant (P ＜ 0.05).Compared with NIHSS score before operation,the score after the treatment showed a decreased trend.And the NIHSS score of MT group was better than that of the IAT group in a week after the treatment (P ＜ 0.05).The bleeding rate was lower in the MT group with statistically significant difference (P ＜ 0.05).Conclusion Compared to IAT,MT can provide broader time window,higher recanalization rate and better outcome in patients with severe acute ischemic stroke.

Objective: To observe the efficacy of unblocking and regulating the Belt Vessel acupuncture method for patients with abdominal obesity in Germany and its influence on the body fat parameters and glycolipids metabolism. Methods: A total of 82 cases of abdominal obesity in Germany were selected. There were two dropout cases in the treatment process. All of the patients received acupuncture at Daimai (GB26), Daheng (SP15), Tianshu (ST25), Zhongwan (CV12), Shuidao (ST28), Waiguan (TE5), and Zulinqi (GB41). The patients received acupuncture therapy once every 2-3 d, 3 times a week. The treatment duration lasted 4 weeks. Before and after treatment, the body mass (BM), waist circumference (WC), abdominal circumference (AC), hip circumference (HC), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and fasting blood glucose (GLU) were measured respectively, and the body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), and body fat rate (BFR) were calculated. Results: After treatment, the total effective rate was 72.5％; the levels of BM, WC, AC, HC, BMI, WHR, WHtR, BFR, TC, LDL-C, and GLU declined significantly compared with those before treatment (P<0.01), while the TG and HDL-C slightly declined, but the differences were statistically insignificant (P>0.05). Conclusion: The unblocking and regulating the Belt Vessel acupuncture method can significantly reduce body fat parameters such as BM, AC, and BFR, and correct the disorders of glucose and lipid metabolism in patients with abdominal obesity in Germany.

Objective To study the expression difference of the insulin-like growth factor-I (IGF-I)and IGF-binding proteins-3,4,5(IGFBP-3,4,5)in the peripheral and local areas in senile hip fracture and discuss the correlation between the expression and the fracture types. Methods The study involved the senile patients (over 65 years) with hip fractures to compare the expressions of peripheral and local IGF-I and IGFBP-3,4,5 and observe the correlation between expression and fracture type.Results The serum and local specimens of 46 patients were collected,with lower level of BMD,IGF-I and IGFBP-3,5 in the intertrochanteric fracture group than the femoral neck fracture group(P<0.001)and with higher level of serum and local IGFBP-4 in the intertrochanteric fracture group than the femoral neck fracture group (P<0.001).Only local IGFBP-4 mRNA had positive correlation with serum markers (R=0.544,P<0.001). Conclusions The expression difference of IGF-I and IGFBP in the peripheral and local serum may be one of pathogenesis leading to different types of hip fractures.Except for the IGFBP-4,the other factors may affect the bone metabolism of the senile hip fractures through different regulatory mechanisms.

Objective To evaluate the change of left atrial function after mitral valvuloplasty in patients with mitral valve prolapse by measuring left atrial strain using two-dimensional speckle tracking echocardiography(2D-STE).Methods Study population consisted of 25 patients with mitral valve prolapse and 25 healthy subjects.High frame rate two-dimensional images were recorded from the apical four chamber view and two chamber view.Images of patients with mitral valve prolapse were respectively recorded at pre-operation,3 days and 3 months post-operation.Left atrial longitudinal strain was measured in two views using two-dimensional strain soft ware.Results ①Compared with the control group,global peak atrial longitudinal strain (PALS),peak atrial contraction strain (PACS) and atrial longitudinal strain during early diastole(ALSED) decreased (P ＜0.01) in patients with mitral valve prolapse,but global timeto-peak of peak atrial longitudinal strain(TPLS) increased(P ＜0.01).Regurgitant jet area/left atrium area (RJA/LAA) in patients with mitral valve prolapse correlated negatively with global PALS(r =-0.620,P ＜ 0.01).② Compared with preoperative group,global PALS,PACS,ALSED and TPLS decreased significantly at 3 days after surgery(P ＜0.01).Global PALS,ALSED(P ＜0.01) and PACS(P ＜0.05)increased at 3 months after surgery,but global TPLS did not differ significantly.Conclusions 2D-STE could accurately evaluate the change of left atrial function after mitral valvuloplasty.

Objective To assess the efficacy of stone fragmentation and clearance of this new intracorporeal ultrasound lithotripter (CQS-01) compared with currently available ultrasound units (EMS-Ⅲ/Ⅳ).Methods Twenty phantom stones composed of dental gypsum were randomly divided into four groups,and CQS-01 ultrasound lithotripter (70％ power and 70％ duty factor),EMS-Ⅲ ultrasound lithotripter (70％ power and 70％ duty factor),EMS-Ⅳ ultrasound lithotripter (type A,70％ power and 70％ duty factor) and EMS-Ⅳ ultrasound lithotripter (type B,70％ power and 100％ duty factor) were used to fragment and removepbantom stones.The mean stone breakdown time and fragment removal time and stone fragmental sizes for the standard ultrasound devices were compared to determine the completeness and efficiency of stone fragmentation and removal.Results The average time for stone breakdown was 7.4 ± 1.9 s,9.4 ± 1.6 s,82.2 ± 12.6 s and 51.4 ± 18.7 s,respectively.There was no significant difference between CQS-01 and EMS-Ⅲ (P ＞ 0.05),but there was significant difference between CQS-01 and EMS-Ⅳ (A or B) (P ＜ 0.001).The average time for stone clearance using the ultrasound devices was 387.8 ± 68.0 s,41 1.6 ± 57.6 s,568.0 ± 119.1 s and 383.6 ± 75.6 s,respectively.In addition,the average size of the largest fragments removed was the same among the groups (＜ 3 mm).Conclusion The ultrasound capabilities in a newly developed lithotriter (CQS-01) exhibited the same ability to fragment and clear phantom stones compared with standard ultrasound devices.

BACKGROUND: Orphanin, which was found in recent years, is an important bioactive polypeptide. Its extensive distribution in the central nervous system and peripheral tissue suggests a function of adjusting global behaviors.OBJECTIVE: To explore the correlation of plasm orphanin level and monoamine neurotransmitters in patients with postpartum depression by determining the levels of orphanin and monoamine neurotransmitters such as 5-hydroxytryptamine (5-HT) and dopamine(DA) in patients.DESIGN: Case-control experiment taking diagnosis as evidence.SETTING: Departments of Obstetrics and Gynecology, Changzheng Hospital and Changhai Hospital, Second Military Medical University of Chinese PLA.PARTICIPANTS: Twenty-five healthy women and seventeen women patients with postpartum depression after delivery who came in the Department of Obstetrics and Gynecology, Changzheng Hospital and Changhai Hospital, Second Military Medical University of Chinese PLA for further consultation during February 2002 to October 2004 were enrolled in this study, and served as control group and postpartum depression group, respectively. All the enrolled women, aged 21 to 43 years, with fair education levels, and voluntarily participated in this study. Women patients of 15 to 25 days after delivery suffered from the incipient postpartum depression with total scores of Edingburgh Postnatal Depression Scale (EPDS) above 13. Informed consents were obtained from all the subjects.METHODS: The levels of orphanin and monoamine neurotransmitters in venous blood from 25 healthy women and 17 women patients with postpartum depression were determined. ① Sample collecting: Blood was taken from women in the postpartum depression group 2 weeks after onset, while from control group 35 days after delivery. ② Assay method:The level of orphanin was determined with radioimmunoassay (RIA). The reagent kit was provided by phoenix company (USA) and the procedure was strictly performed according to the instructions on the reagent kit. The levels of 5-HT and DA were measured with high-performance liquid chromatography or electrochemical detection method.MAIN OUTCOME MEASURES: ① Changes in the levels of orphanin as well as 5-HT and DA in postpartum depression group and control group. ② Correlation of the total scores of EPDS and the levels of orphanin in postpartum depression group.RESULTS: Twenty-five healthy women and seventeen women patients with postpartum depression after delivery all participated in the result analysis. ① The level of orphanin in the postpartum depression group[(27.39±6.04) ng/L] was significantly higher than that in the control group [(10.37±3.65) ng/L](P ＜ 0.01),the levels of 5-HT in the postpartum depression group [(0.93±0.21) μmol/L] was remarkably lower than that in the control group[(1.43±0.36) μmol/L](P ＜0.05) ,and the levels of DA in postpartum depression group[(2.15±0.41) μmol/L] was obviously lower than that in the control group [(3.64±0.72) μmol/L]( P ＜ 0.01). ②The level of orphanin was negatively correlated with those of 5-HT and DA in postpartum depression group(r = -0.601 , -0.593,P ＜ 0.05). ③ The total scores of EPDS were significantly positively correlated with the level of orphanin (r = 0.512, P ＜ 0.05), and negatively correlated with the levels of 5-HT and DA (r = -0.571,-0.526, P＜ 0.05).CONCLUSION: The level of orphanin in patients with postpartum depression is increased and is negatively correlated with the levels of 5-HT and DA, but positively correlated with the total scores of EPDS.
