Purpose To assess the effect of pelvicfloor electrical stimulation treatment by transperineal sonography, so as to provide guidance for postpartum pelvic floor rehabilitation.Materials and Methods Thirty-one delivery women who received postpartum pelvicfloor rehabilitation were selected as research group and 30 non-pregnant young women as control group in the study. Pelvicfloor electromyography treatment was taken in research group, and transperineal sonography was undergone in quiet state and pressure state (Valsalva operation) before treatment, after the fifth treatment and after the tenth treatment respectively to measure the bladder neck to the public symphysis edge distance (Dr, Ds), bladder neck angle (θr,θs) and bladder rotation angle (θ). A comparison was made between the research group and control group.Results①Dr and Ds in research group were both lower than those in control group (P<0.05), butθr,θs andθ were all higher than those in control group (P<0.05).②Dr and Ds showed a gradual increase (P<0.05) whilstθr presented a gradual decrease before the treatment, after the fifth treatment and after the tenth treatment (P<0.05).Conclusion Natural childbirth may damage the function of pelvicfloor; electrical stimulation of pelvic therapy is effective on postpartum pelvicfloor rehabilitation; and transperineal sonography can objectively assess the effect of this therapy.

In order to investigate the genetic basis of morphological variation of tetraploid plantlets of Atractylodes macrocephala, diploid plantlets were taken as experimental material, sterile filtration colchicine was used to soak 0.5-1.0 cm long buds. The difference between morphology and stomatal of diploid and tetraploid of A. macrocephala was compared, and genome polymorphism was explored by AFLP. The results showed that the buds dipped in 0.1% colchicine solution for 36 h was optimal conditions to induce tetraploid of A. macrocephala with induction rate of 32.0%. Morphological indexes such as leaf area index, leaf length and width, the density of stomas and the number of chloroplast of tetraploid were distinctly different from diploid. Four hundred and fifty-one bands ranging with 80-500 bp were amplified with 24 pairs of primers, the rate of polymorphism was 32.59%. These amplification sites of diploid were different from tetraploid of A. macrocephala, and the differences in morphology of them were reflected in the DNA polymorphism.

Objective To evaluate the feasibility of Mycobacteria growth indicator tube ( MGIT ) liquid culture combined with rifampin resistance test real-time PCR ( Xpert MTB/RIF test) in the diagnosis of tuberculosis.Methods 652 cases of suspected pulmonary tuberculosis from October 2014 to March 2015 in Quzhou People′s Hospital were enrolled. The morning sputum samples were collected for acid-fast staining, L?wenstein-Jensen ( L-J) culture, BACTEC MGIT culture and Xpert MTB/RIF test.Samples with positive results of MGIT liquid culture were subjected to strain identification and drug sensitivity test with fluid method.Methodological comparison between four methods was made and the performance of MGIT liquid culture combined with Xpert MTB/RIF test in the rapid diagnosis and drug resistance detection in Mycobacterium tuberculosis was evaluated by chi-square test. Results Among the samples from 399 confirmed tuberculosis patients, the diagnostic sensitivity of the 4 methods ( acid-fast staining, L-J culture, MGIT culture and Xpert MTB/RIF test) were 17.0%(68/399), 23.8%(95/399), 37.8% (151/399) and 37.3%(149/399) respectively.The sensitivity and specificity of MGIT culture combined with Xpert MTB/RIF test was 39.8%(159/399) and 94.8%(240/253).The sensitivity of MGIT culture combined with Xpert MTB/RIF test was significantly higher than acid-fast staining (χ2 =50.9, P<0.01 ) and L-J culture (χ2 =23.7,P<0.01).The average detection time of MGIT culture was 7.5 days ( smear positive and Xpert MTB/RIF positive), 13.4 days (smear negative and Xpert MTB/RIF positive) and 16.9 days ( smear negative and Xpert MTB/RIF negative) .The sensitivity and specificity of Xpert MTB/RIF test in rifampin resistance detection were 9/9 and 97.3% ( 129/132 ) respectively.The average detection time of fluid method for drug sensitivity test was 8.3 days.Conclusions MGIT liquid culture combined with Xpert MTB/RIF test can detect Mycobacterium tuberculosis and the drug sensitivity rapidly.The method is highly sensitive and specific.It is important for clinical diagnosis and treatment of tuberculosis.

Objective To analyze factors influencing short-term effect of presurgical pharmacological thera-py and transsphenoidal microsurgery for somatotropinomas. Methods The clinical data of 53 patients underwent presurgical pharmacological therapy and transsphenoidal surgery for somatotropinomas were retrospectively analyzed in order to search for factors influencing effect of presurgical pharmacological therapy and transsphenoidal surgery for somatotropinomas. Results Serum GH inhibition rates decreased<50.00%from baseline in 62.26%of patients receiving presurgical pharmacological therapy. Statistical analysis concerning the influence of sex , neuropathological evaluation, tumor size and presence of invasion on presurgical pharmacological therapy effect were performed using a chi-squared test, no significant correlation was found among these factors and presurgical pharmacological therapy effect. Total remission rates were 43.40%, Statistical analysis concerning the influence of sex , neuropathological e valuation, tumor size, presence of invasion and presurgical pharmacological therapy effect on remission rate were performed using a chi-squared test, a significant correlation was found among tumor size, presence of invasion, presurgical pharmacological therapy effect and remission rate , while no significant correlation was found among the rest of the factors. Further Logistic regression analysis demonstrated a significant correlation among tumor size , presence of invasion and remission rate , while no significant correlation was found between presurgical pharmacolog-ical therapy effect and remission rate. Conclusions Presurgical pharmacological therapy effect revealed no signifi-cant correlation with sex, neuropathological evaluation, tumor size or presence of invasion. Total remission rate cor-related with tumor size and presence of invasion. A better presurgical pharmacological therapy effect may indicated a better outcome, while postoperative remission rate revealed no significant correlation with presurgical pharmacologi-cal therapy in our series.

OBJECTIVETo analyze clinical features, therapeutic effects and prognostic factors of patients with mantle cell lymphoma (MCL).

METHODSClinical data of 37 MCL patients hospitalized in our hospital from January 2000 to March 2010 were retrospectively analyzed.

RESULTSThe median age was 62, with a male predominance. 97.30% of the patients were in Ann Arbor stage III ∼ IV, 54.05% with B symptoms, 64.86% with bone marrow involvement, 29.73% with splenomegaly, 24.32% with lymphocytosis and 51.35% with elevated LDH. Ki-67 was detected in 22 cases, and patients with Ki-67 ≤ 40% accounted for 68.18%. Of 37 cases, the overall response rate (ORR) of rituximab combined with chemotherapy was 92.31%, being higher than those of CHOP (46.15%) and CHOP + IFN (42.86%) regimens. There were statistical differences in the 3-year progression-free survival (PFS) and overall survival (OS) between rituximab + chemotherapy and CHOP or CHOP + interferon regimens (P < 0.05, respectively). Splenomegaly, elevated WBC, lymphocytosis and Ki-67 > 40% were identified as adverse prognostic factors.

CONCLUSIONMost patients with MCL were older adults, with a male predominance and usually had bone marrow involvement and poor prognosis. Rituximab combined with chemotherapy could improve ORR and OS of MCL.

OBJECTIVETo observe metabolomic changes in urine of chronic superficial gastritis (CSG) patients with Pi-qi deficiency syndrome (PQDS) or Pi-Wei dampness-heat syndrome (PWDHS), thereby providing scientific evidence for syndrome typing of them.

METHODSUrine samples were collected from CSG patients with PQDS/PWDHS and healthy volunteers, 10 in each group. Proton nuclear magnetic resonance spectroscopy (1H-NMR) based metabonomic analysis was performed on urine samples. Contents of related biomarkers were analyzed by principal component analysis (PCA), partial least square discriminant analysis (PLS-DA), and urivariate statistical analysis.

RESULTSPLS-DA analysis showed that metabolites among CSG patients with PQDS/PWDHS and healthy volunteers could be mutually distinguished. Seven differentially identified metabolites were screened from urines of CSG patients with PQDS and healthy volunteers included glutamate, methionine, α-oxoglutarate, dimethylglycine, creatinine, taurine, and glucose. Four differentially identified metabolites were screened from urines of CSG patients with PWDHS and healthy volunteers included 2-hydroxybutyric acid, trimethylamine oxide, taurine, and hippuric acid. Eleven differentially identified metabolites were screened from urines of CSG patients with PQDS and PWDHS included fucose, β-hydroxybutyric acid, alanine, glutamate, methionine, succinic acid, citric acid, creatinine, glucose, hippuric acid, and lactic acid.

CONCLUSIONThe metabolic differences of CSG patients PQDS and PWDHS mainly manifested in glycometabolism, lipid metabolism, and amino acids catabolism, and 1H-NMR based metabonomics may be used in classified study of Chinese medical syndrome typing.

OBJECTIVEIn cervical lesions, the overexpression of p16INK4a has been reported to be closely associated with human papillomavirus (HPV) infection. This study is designed to evaluate the role of p16INK4a as a biomarker in liquid-based cervical cytology screening.

METHODSSeventy-four specimens from the patients in our hospital were collected for this study. After cytological examination with liquid-based cervical smears, high-risk HPV (HR-HPV) DNA was then detected by Hybrid Capture II assay, and the rest cells were immunostained for p16INK4a.

RESULTSOf the 74 specimens, 10 were diagnosed as negative, 15 as atypical squmous cells of undetermined significance (ASC-US), 28 as low-grade squamous intraepithelial lesion (LSIL), 5 as atypical squmous cells which could not be excluded as HSIL (ASC-H), 11 high-grade squamous intraepithelial lesion (HSIL) and 5 as squamous cell carcinoma (SCC). The positive specimens of p16INK4a were 2, 5, 8, 3, 9, 5, respectively, in the above subgroups; meanwhile, the positive specimens of HR-HPV were 1, 4, 9, 3, 7, 5, respectively, in the above groups. The positive rate of both p16INK4a and HR-HPV in HSIL, ASC-H and SCC were obviously higher than that in LSIL, ASC-US and negative cases.

CONCLUSIONPositive rate of p16INK4a and HR-HPV is highly correlated with the grade of the cervical lesion. p16INK4a immunocytochemical staining may be used as a biomarker to increase the sensitivity of cervical cytology screening and the specificity of HPV test.
