The signal in Sertoli cells began to appear in Ⅱ Ⅵ stages, strongest in Ⅶ Ⅷ stages and weakest in Ⅸ Ⅰ stages ( P

Objective To compare the efficacy and safety of a new low-dose oral contraceptive pill (YAZ) containing drospirenone 3 mg and ethinylestradiol 20 μg with placebo in reducing symptoms of premenstrual dysphoric disorder (PMDD). Methods This multicenter, double-blind, randomized clinical trial consisted of 2 run-in and 3 treatment cycles (84 days) with daily symptom charting; 187 women with symptoms of PMDD were randomized to either placebo group (n=94) or YAZ group (n=93), and assessed with daily record of severity of problems scale (DRSP) and clinical global impressions scale (CGI) before, during and after the treatments. Hormones were administered for 24 days, followed by 4 days of inactive pills. Results Compared with baseline level of DRSP, both groups got improvement after treatment; the YAZ group (median-28.7, range:-82.5 to 2.3) had greater improvement than that in the placebo group (median-23.7, range:-86.0 to 11.8), while there was not significant difference (P>0.05). The main adverse effects of YAZ included intermenstrual bleeding [13% (12/93) versus 3% (3/94)], menorrhagia [9% (8/93) versus 1%(1/94)], nausea [5%(5/93) versus 4%(4/94)] and skin rash [4%(4/93) versus 2%(2/94)]. Conclusions YAZ could improve symptoms of PMDD better than placebo, while without statistic significance in this study. The most common adverse effects are intermenstrual bleeding, menorrhagia, nausea and rash.

Objective To explore the effect of Ginkgo biloba extract (EGb761) on apoptosis of K-ras mutational human colon cancer cells DLD1(DLD1/G13D)and its mechanism. Methods Human colon cancer cell lines DLD1/G13D and DLD1 with K-ras wild type(DLD1/WT)were cultured in vitro,the cell proliferation and apoptosis after 24 h of EGb761 were measured. Proteins involved in related signal pathway were detected by Western blot or ELISA. Results EGb761 reduced cell proliferation and induced cell apoptosis in a concentration-dependent manner in DLD1/WT and DLD1/G13D cells. EGb761 downregulated the expression of RIP1, impaired the phosphorylation of IκB and decreased the level of NF-κB in DLD1/WT and DLD1/G13D cells[DLD1/G13D: (24±4)%, DLD1/WT: (29±9)%(P<0.05). Conclusion EGb761 restrains the proliferation and induces the apoptosis of DLD1/WT and DLD1/G13D cells. The mechanism may be related to the degradation of RIP-1 and inhibition of activation of NF-κB signaling pathway.

Objective: To analyze the characteristics of the healthy state of TCM (Traditional Chinese Medicine) of female, and preliminarily constructs the model of TCM health status identification of female with menstrual cycle. Methods: The text of disease diagnosis and syndrome differentiation of menstrual-cycle-linked disorders from Guidelines for diagnosis and treatment of common disease of gynecology in Traditional Chinese Medicine was analyzed, and the symptoms related with viscera functions, the waxing and waning of qi and blood, and pathogenic properties were extracted. The questionnaires of diseases and syndrome elements differentiation of female by calculating the weight relationship between symptoms and health status were designed to estimate the interior state of waxing and waning of yin-yang by figuring out the different periods of menstrual, and in the last step, Constitution in Chinese medicine Questionnaire was used to identify the constitution. Through the above four identification methods, a comprehensive identification of the female's health status of TCM was formed. Results: Through the disease identification model, we distinguished the state of disease and yet disease. And through the syndrome elements differentiation model, we knew the viscera functions, the waxing and waning of qi-blood and yin-yang, and pathogenic properties. And by identifying the internal qi-blood and yin-yang status, we initially built the model that can identify health status of female integrally with the constitution. Conclusion:The model identification results can reflect the comprehensive health status of female in multiple dimensions. It can make a fine classification of women.s TCM health status. It can not only help to know the previous health status but also help to speculate the future health trend, which contributes to the formulation of personalized health interventions of follow-up.

Objective To investigate the preoperative magnetic resonance imaging (MRI)examination of the distribution of neurovascular bundles (NVB) around the prostatic capsule,and its clinical value in the nerve-sparing laparoscopic radical prostatectomy (NS-LRP).Methods The clinical data of 42 patients with clinically localized prostate cancer who were admitted from January 2008 to January 2017 were retrospectively analyzed.Age ranged from 58 to 74 years,with an average of 68 years.Preoperative serum PSA range from 0.94 to 12.28 ng/dl,with an average of 7.01 ng/dl.Preoperative Gleason score range from 6 to 8,with an average of 6.Clinical stage:T1-T2 37 cases,T3 5 cases.The average preoperative International Erectile Function Index questionnaire-5 (IIEF-5) 21,of which 23 cases had normal erectile function (IIEF-5 ＞ 22).All the 42 patients underwent MRI examination before operation.According to the distribution of NVB around the prostatic capsule,they were divided into 3 groups:17 cases in group A,and no NVB was evident in all cases.In group B,8 cases were visible but not obvious.In group C,17 cases were evident NVB.There was no significant difference in age,preoperative serum PSA and Gleason score between the three groups (P ＞ 0.05).The preoperative IIEF-5 in group A,B,and C were 19.5,22.8,and 21.5,respectively,with no statistically significant difference (P ＞ 0.05).All 42 cases received NS-LRP under general anesthesia.The differences in IIEF-5 before and after surgery were compared between the three groups.Results In this study,42 cases were successfully completed.42 patients were followed up for 12 to 36 months,with an average of 14.1 months.In group A,B,and C,postoperative IIEF-5 was 8.0,14.1,and 15.5,respectively,which was statistically significant compared with preoperative values (P ＜ 0.05).The decrease of IIEF-5 afteroperation in group A was significantly different from that of group Band C (P ＜0.05).Conclusions Compared with patients with visible NVB on MRI examination,patients have no visible NVB observed on MRI with erectile function-related nerves around the prostatic capsule may be walking on both sides of the prostatic capsule and spreading over the entire anterior ventral surface of the prostate.To maxium-preserve NVB and postoperative erectile function to the utmost,NS-LRP surgery should be more accurately dissected on both sides and ventral side of the prostatic capsule.

Objective: To evaluate the effects of surgical navigation technique in the reconstruction of traumatic orbital wall defect.Methods: 20 patients underwent the operation with the aid of navigation for repairing traumatic orbital wall defect as the test group. 20 patients were treated without navigation as the control group. Treatment outcome was evaluated by correction of exophthalmos, orbital volumes and patient's self-satisfaction.

The patient's satisfaction value of the navigation group was higher than in the control group (P ＜ 0. 05) . The operation duration in the navigation group was less than in the control group (P ＜0. 05) . Conclusion: Surgical navigation can improve the accuracy and the effects of operation for orbital defect reconstruction.

OBJECTIVEThe aim of this study was to detect the plasma concentration of OLC1 (overexpressed in lung cancer 1) protein as a potential cancer biomarker, and evaluating its clinical application value in the diagnosis of non-small cell lung cancer (NSCLC).

METHODSWe prepared OLC1 antibody with OLC1 full length protein, in 5-6-week old Bal B/c mice. Each mouse was immunized four times at a dose of 15-30 µg antigen protein, and the interval between two consecutive immunizations was two weeks. Antibody screening was made by ELISA and Western blot, and a double antibody sandwich ELISA kit was developed. We used this established ELISA kit to detect the plasma concentration of OLC1 protein in 281 NSCLC patients and 92 gender- and age-matched healthy controls. Area under the receiver operating characteristic curve (AUC) was used to evaluate the detection efficacy of OLC1.

RESULTSWe obtained 11 OLC1 monoclonal antibodies and successfully established the ELISA kit to detect the plasma concentration of OLC1 with a detection range from 1.95 ng/ml to 62.50 ng/ml. OLC1 concentration in the case group (124.69 ng/ml) was significantly higher than that in the control group (67.07 ng/ml, P < 0.001). In the scenario of distinguishing NSCLC from control group, AUC result was 0.69. When the cut-off was set at 67.72 ng/ml, the sensitivity and specificity was 84.4% and 51.1%, respectively. In term of distinguishing early lung cancer (IA) from normal controls, the AUC, sensitivity and specificity were 0.68, 77.8% and 54.4%, respectively.

CONCLUSIONThe plasma concentration of OLC1 protein is significantly elevated in NSCLC patients. OLC1 may be as a potential cancer biomarker applied in clinical diagnosis.

Objective: To explore pulse characteristic of the health female college students and their relationship with menstrual cycle. Methods: The subjects were 17 female college students of Jiangxi University of Traditional Chinese Medicine. Pulse test was performed with pulse bracelet. The detection time was every day in the wake and has not yet get up and wake up at any time before going to bed with a pulse-taking bracelet, and recorded the current menstrual cycle information. The pulses of the wake that has not yet get up and wake up at any time before going to bed took consistency analysis of the record with Kruskal Wallis Test. The pulse of menstruation stage analysis was compared with chi-square test. Results: The pulses of the wake that has not yet get up and wake up at any time before going to bed consistency was poor except rapid pulse (P＞ 0.05) . The occurrence frequency of slippery pulse and string-like pulse were 55.21％ and26. 03％ respectively. The pulses of premenstrual period, post menstrual period and menstrual period were not much different from others. The occurrence frequency of moderate pulse, string-like pulse, unsmooth pulse, slippery pulse in intermenstrual period respectively were 40.68％, 44.07％, 30.51％, and 40.68％. The occurrence frequency of moderate pulse, string-like pulse, unsmooth pulse, slippery pulse in-non intermenstrual period respectively were 17.38％, 24.69％, 10.45％, 56.30％. The difference was significant (P ＜ 0.05) . Conclusion: The female college students are mainly in terms of slippery pulse. The occurrence frequency slippery pulse in intermenstrual period respectively are less common. The string-like pulse, moderate pulse, unsmooth pulse in intermenstrual period are more common than in-non intermenstrual period.
