Objective To evaluate the efficacy and safety of the TVT-Secur procedure for female stress urinary incontinence (SUI). Methods Analyze retrospectively the preoperative, intraoperative and postoperative complications and follow-up data of 27 SUI patients from October 2008 to May 2010. 20 cases were simple SUI, and 7 cases were mixed SUI. The average age was 56.1 ± 10.7 years (range, 35-77), the average parity was 2.8-±- 1.4 (range, 1-6), the average body mass index was 25.6±2.5, and the average course of the disease was 6.8±7.2 yeas (range, 1-30). Two cases had past history of pelvic surgery without any anti-incontinence surgery. Mashall-marchett test was positive in all patients, with an average abdominal leak point pressure (ALPP) of 60.9±27.5 cm H2O (range, 27- 120 cm H2O). The mean International Consultation on Incontinence-Short Form (ICIQ-SF) score was 11.2 ± 1.8 (range, 7- 14) before surgery. Results 27 patients underwent TVT-Secur procedure, of which 19 cases underwent "U" procedure, and 8 cases underwent "H" procedure. The mean operation time was 15.3±1.4min (range, 13- 19 min). There were no intraoperative bladder or urethral injury, and no obturator vessel or nerve damage. The blood loss was 10 to 50 ml, and the maximum urinary flow rate was 25. 4±13. 1 ml (range, 4-50 ml). Three eases had mild dysuria(11. 1%), and 3 cases had wound effusion(11. 1%). Followed up for 12. 6 ±6. 7 months (range, 3-21 months). 10 cases complained of bladder overactivity symptoms such as frequency, urgency, and urge incontinence, and no case had vaginal erosion. Therapeutic efficacy: 15 cases were cured (56%), 8 cases were improved (30%), and 4 cases were ineffective (15%). Conclusions TVT-Secur procedure is a simple, safe and minimally invasive surgery, while the cure rate is low. The long-term efficacy needs great amount of clinical data and long-term follow-up to prove.

OBJECTIVE To evaluate these activities of Rg1 in the 1-methyl-4-phenyl-1,2,3,6-tetrahy?dropyridine (MPTP)/probenecid (MPTP/p)-induced PD mouse model for the first time and to elucidate the underlying mechanisms. METHODS Male C57BL/6 mice were randomly assigned to six groups. One hour prior to MPTP/p injection, Group Ⅲ-Ⅵ mice received 10 mg·kg-1, 20 mg·kg-1, or 40 mg·kg-1 Rg1 or 3 mg·kg-1 selegiline, respectively, orally from D (-3) to D49. Group Ⅰ-Ⅱ mice received solvent water. Subsequently, GroupⅡ-Ⅵ mice received by injection MPTP-HCl (25 mg·kg- 1 bw dissolved in 0.9% saline, sc) on a 40-d schedule at intervals of 4 d between consecutive doses in combination with an adjuvant drug, probenecid (250 mg·kg- 1 bw in 0.03 mL of DMSO, ip); GroupⅠ mice were injected with saline and probenecid. Behavioral performance was assessed in the open field test, pole test and rotarod test. Neurotransmitters in the striatum were detected using HPLC. Protein levels were measured by Western blot. Pathological characteristics were examined by immunohistochemistry. Ultrastructure changes were observed by electron microscopy. RESULTS Oral treatment with Rg1 significantly attenuated the high MPTP-induced mortality, behavior defects, loss of dopamine neurons and abnormal ultrastructure changes in the SNpc. Other assays indicated that the protective effect of Rg1 may be mediated by its anti-neuroinflammatory properties. Rg1 regulated MPTP-induced reactive astrocytes and microglia and decreased the release of cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1b (IL-1b) in the SNpc. Rg1 also alleviated the unusual MPTP induced increase in oligomeric, phosphorylated and disease-related a-synuclein in the SNpc. CONCLUSION Rg1 protects dopaminergic neurons, most likely by reducing aberrant a-synuclein-mediated neuroinflammation, and holds promise for Parkinson disease therapeutics.

A highly sensitive, rapid and selective liquid chromatography-tandem mass spectrometry(LC-MS/MS) method for the quantitative determination of retinamido-ester in rat plasma was developed and validated. A simplified protein precipitation with acetonitrile was employed for the sample preparation.The separation was carried out on an Agilent TC C18 column ( 150 mm×4. 6 mm ID, 5 μm particle size)with the mobile phase consisted of methanol-water-formic acid (93 : 7 : 0.1). Simvastatin was used as internal standard. The detection was performed on a trap-quadrupele tandem mass spectrometer by selected reaction monitoring (SRM) scan mode via atmospheric pressure chemical ionization (APCI). The range of and inter-day precision values were between 95.97% and 104. 43%, and RSD was between 4. 63% and 10. 69%, respectively. This method was applied to determine the pharmacokinetic parameters. The main pharmacokinetic parameters of retinamido-ester after oral administration via gastric gavage of 2. 5, 5, 10mg·kg-1 were as follows,T1/2;(11.28±7.23),(8.90±3.82),(8.01±5.56)h; AUC0-∞:(103.41±61.46),(190.23±74.99),(421.66±299.20)ng·h·mL-1;MRT:(6.31±0.75),(5.98±0.71), (6.18±0.97) h; CL/F: (30. 10 ± 13.67), (29.58±10.59), (31.18 ±17.51)L·h-1·kg-1;Vd/F:(414.94±159.82),(356.16±139.85),(369.28±322.73)L·kg-1,respectively.

Objective To study the genotypes of representative Mycobacterium tuberculosis (M.tuberculosis) strains from China with spacer oligonucleotide typing (spoligotyping),and to investigate the prevalence of different genotypes TB in China,and analyse the relationship between genotype and drug resistance.Methods 4017 clinical isolates were collected by Chinese Center for Disease Control and Prevention from 2007 to 2008 in 31 provinces in China according to sampling principle of epidemiology.Drug susceptibility testing was performed using proportion method,and spoligotyping was chosen to carry out genotyping of these M.tuberculosis.In addition,chi-square test was used to compare the differences among the detection rate of different genotypes.Results Among the 4017 M.tuberculosis isolates,2500 ( 62.2％ ) isolates belonged to Beijing genotype.The percentage of Beijing genotypes in the northern of China was higher than that in the southern of China ( 76.5％ vs.53.2％,x2 =219.69,P ＜ 0.05 ),while T1 genotypes were more common in the southern China,compared with that in northern China ( 13.3％ vs.4.3％,x2 =219.69,P ＜ 0.05 ).The differences were statistically significant.The proportions of Rifampinresistant (21.7％ vs.21.7％ ),Ofloxacin-resistant (4.9％ vs.2.4％ ) and Multidrug-resistant ( 11.3％vs.7.4％ ) isolates among Beijing genotype strains were significantly higher than those among non-Beijing strains (x2 =22.10,14.42 and 14.83,respectively,P ＜ 0.05 ).Conclusions Beijing genotype was still predominant epidemic genotypes.The percentage of Beijing genotype showed difference between distinct areas,and the percentage of Beijing genotypes in northern China was higher than that in southern China.Beijing genotype strains reveal correlation with Rifampin-resistance,Ofloxacin-resistance and Multidrug-resistance.

0.05).Moreover,the growth curves of the two kinds of cells were similar.Con- clusions The cell growth properties of cultured transplanted rabbit SMG are similar to that of normal SMG,the cytobiological charac- teristic of transplanted autologous free rabbit SMG are not changed evidently.

Aim To explore the antidepressant effect and the mechanism of self-made prescription of strengthening spleen and replenishing Qi ( SMP-SS-RQ) . Methods The depression model of chronic un-predictable mild stress ( CUMS ) was established in mice. The animals were randomly divided into control group, model group, SMP-SSRQ low, middle and high dose groups (8, 16, 32 mg·kg-1), with 12 mice for each group. The control group and the model group were given the same volume of saline, and other groups were given corresponding dose of SMP-SSRQ. Animals of each group were administered by gavage twice a day for two weeks. Behavioral indexes of mice were deter-mined by open field experiment, sugar consumption test, forced swimming test and tail suspension test. Quantitative real-time PCR (qPCR) and Western blot were respectively performed to detect mRNA and pro-tein expression levels of Igsf11 , Pdia2 and Sec14 l2 inprefrontal cortex and hippocampus. Results Com-pared with model group, depressed mice' s horizontal mobile score, upright number and the sugar water pref-erence index increased and FST as well as TST de-creased in all SMP-SSRQ groups(P<0.05). The de-pression symptoms in mice were obviously improved by SMP-SSRQ therapy. Low and high doses of SMP-SSRQ significantly reduced mRNA and protein expression lev-el of Igsf11 , Pdia2 and Sec14 l2 in the prefrontal cortex and hippocampus of the depressed mice, presenting significant statistical difference compared with model group ( P<0.05 ) . Conclusions SMP-SSRQ can ef-fectively improve mouse depressive behavior, and its mechanism may be related to the down-regulation of Igsf11 , Pdia2 and Sec14 l2 in mouse prefrontal cortex and hippocampus.

Objective:To investigate the changes of eosinophil(EOS) in feces of children with allergic enteritis caused by milk protein, and to provide basis for diagnosis and treatment of allergic enteritis.Methods:From July 2018 to June 2019, 70 children with milk protein allergic enteritis (allergic group), 50 children with non allergic common diarrhea (non-allergic group) and 50 children with healthy physical examination (healthy control group) were selected from Children′s Hospital of Nanjing Medical University.White blood cell(WBC), hemoglobin(Hb), blood platelet(PLT), EOS and the percentage of EOS(EOS%) of the 3 groups were counted by automatic hematology analyzer.The EOS in the feces of the 3 groups and the allergic group after treatment were counted by Gomori staining, and the correlation between EOS in the feces and milk protein allergic enteritis was analyzed.Results:For allergic group, EOS count in peripheral blood was(0.71±0.74)×10 9/L, EOS% was (7.56±5.96)%, and PLT was (382.96±85.98)×10 9/L.For non-allergic group, EOS was (0.31±0.18)×10 9/L, EOS% was (3.53±2.26)%, PLT was(315.12±69.81)×10 9/L.For healthy control group, EOS was(0.31±0.15)×10 9/L, EOS% was (3.66±1.65)%, and the PLT was(307.56±85.20)×10 9/L.The number of EOS, EOS% and PLT in allergic group were higher than those in non-allergic group and healthy control group ( F=13.606, 19.055, 16.074, all P<0.05). The number of EOS in feces of allergic group[(10.75 ±17.17)/ 50 fields at ×1 000]was significantly higher than that of non-allergic group[(1.16±3.09)/50 fields at ×1 000], the difference was statistically significant ( F=17.25, P<0.05), and there was no EOS in feces of healthy control group.After 4 weeks of avoidance of milk, EOS in feces decreased significantly in allergic group [(2.26±5.32)/50 fields at ×1 000], the difference was statistically significant ( t=5.822, P<0.05), while EOS in blood decreased [(0.56±0.47)×10 9/L], the difference was not statistically significant ( t=1.981, P>0.05). Conclusions:EOS in fecal of children with milk protein allergic enteritis increased obviously and decreased after treatment, is helpful to guide the clinical diagnosis and may become a new indicator of efficacy monitoring.

Background: and Purpose We aimed to determine the clinical features of Miller Fisher syndrome (MFS) in southern China and compare them with those presenting in other countries. Methods: We collected the medical records of patients diagnosed with MFS during 2013–2016.We analyzed the age, sex, onset season, precursor events, clinical symptoms and signs, findings of nerve conduction studies (NCS), cerebrospinal fluid (CSF), therapeutic remedies, nadir time, and length of hospital stay of patients with MFS in southern China. We concurrently compared the differences between urban and rural areas and between patients with incomplete ophthalmoplegia (IO) and complete ophthalmoplegia (CO). Results: The study enrolled 72 patients: 36 from rural areas and 36 from urban areas, and 50 males and 22 females. The mean age at onset was 47.72 years, and 30 (41.7%) and 21 (29.2%) patients developed MFS in spring and winter, respectively. The typical triad of ophthalmoplegia, ataxia, and areflexia was observed in 50 (69.4%) patients. A history of upper respiratory tract infection 1 week before onset was found in 52.8% of the patients, while 5.6% experienced gastrointestinal infections and 48 (73.8%) exhibited albuminocytological dissociation in the CSF study. Only 26 (36.1%) patients presented abnormalities in NCS. Moreover, restricted outward eyeball movement presented in 83.5% of the patients with classic MFS and acute ophthalmoplegia, and bilateral symmetrical ophthalmoplegia presented in 64.2%. With the exception of the higher proportion of NCS abnormalities in urban areas (47.2% vs. 25.0%), urban and rural differences were insignificant regarding sex ratio, age at onset, high-incidence season, precursor events, disease characteristics, and albuminocytological dissociation in the CSF. Furthermore, patients with CO were older than those with IO (64.53±7.69 vs. 43.19±14.40 years [mean±standard deviation], p<0.001). Conclusions The patients with MFS were mostly male and middle-aged, and most presented in winter and (especially) spring. More than half of the patients had clear precursor events, most of which were classic MFS with the typical triad. More than 70% of the patients presented albuminocytological dissociation in the CSF. NCS abnormalities were uncommon in MFS. The age at onset was lower in patients with IO than in patients with CO; bilateral symmetrical extraocular muscle paralysis was the most common symptom, and the external rectus was the most frequently involved muscle.

The aim of this study was to investigate the clinical characteristics and prognosis of acute erythroleukemia (AEL, AML-M6). The clinical features and results of morphologic, immunophenotypic, cytogenetic and molecular biologic detections were retrospectively analyzed in 13 cases of AEL from 305 acute leukemia patients hospitalized between October 2007 and October 2012. The results showed that the expression of erythroid and non-erythroid cells increased at the same time. The myeloid antigens mainly expressed CD13/CD33/CD117/CD34, while the erythroid antigens expressed Gly and CD71. The karyotypic detection indicated that there were 1 case with normal karyotype, 3 cases with simple karyotypic abnormality and 2 cases with complex karyotypic abnormality, the other cases were not detected. The molecular biological detection found that the poor prognosis gene existed in 5 cases [38.5% (5/13)], including 3 cases with MLL-MLL fusion gene, 1 case with MLL mutation, and 1 cases with NRAS gene mutation, the abnormal genes were not detected in remainder 8 cases. After chemotherapy with decitabine, the complete remission (CR) rate achieved 53.5% (7/13), partial remission (DR) rate achieved 15.4% (2/13). Finally, 8 patients received allo-HSCT, the median overall survival (OS) was 20.7 months, 3 year survival rate was 79%, 3 year disease-free survival rate was 78%. It is concluded that the acute erythroleukemia is a rare subtype of AML, which is transformed from MDS and has harmful genes and poor prognosis. Allo-HSCT and treatment with decitabine may enhance the survival rate of AEL.

The study was aimed to investigate the clinical characteristics of acute myeloid leukemia (AML) with CBFB-MYH11 gene. The clinical data of 12 cases were analyzed retrospectively, including age, clinical characteristics, immunophenotype, treatment protocols and efficacy as well as the prognosis. The results indicated that 12 patients with CBFB-MYH11 were detected in 293 AML patients. The median age of the 12 patients was 32.5 (21 - 57) years old. According to French-American-British (FAB) classification, 66.7% (8/12) patients was diagnosed as M4Eo and 33.3% patients was diagnosed as M4. At new diagnosis, the median WBC count was 19.8×10(9)/L (2.46 - 164.30×10(9)/L). The WBC count > 100×10(9) was found in 16.7% patients (2/12). The complete remission (CR) rate after 1 and 2 cycles of induction chemotherapy were 83.3% and 16.7% respectively, so the total CR rate was 100%. Estimated 5-year relapse-free survival (RFS) and overall survival (OS) were 80% and 83%, respectively. It is concluded that patients with CBFB-MYH11 are usually M4Eo and M4. Patients with this fusion gene are often associated with high frequency of CD33, CD34, CD117, HLA-DR, CD15, CD64 and CD14 expression. Patients with CBFB-MYH11 have a tendency of higher CR rate, longer RFS and OS.
