Objective To explore the management,curative effect and safe of superficial bladder tumor(BT)by greenlight photoselective vapontion per urethra(GPVPU). Methods 32 patients of BT were treated by GPVPU,and operation time,postoperative complications,relapse rate and so on were observed. Results All cases were completed successfully. No complication happened in operations. Urinary canal was detained 2 ～4 days and bladder washout(BW) did not need after operation. Follow-up average time was 16 months. Irrigation chems of bladder and cystoscopy were applied routinely. Conclusion GPVPU was safe and effective in treatment of superficial bladder tumor.

Objective To explore the management of benign prostatic hyperplasia(BPH)by photoselective vaporization of prostate(PVP)and curative effect in the near future. Methods Clinical data of 60 BPH patients underwent PVP were retrospctively aralyzed.The changes of IPSS and QOL and the max urine flow rate and residual urine volume(RUV)perioperatively were compared through observations of the operation time and complication. Results The therapeutic efficacy was favourable.No transurethral resection of prostate(TURP)syndrome and uroclepsia happens.IPSS(t=2.471,P <0.05)and QOL(t=2.392,P <0.05)and the max urine flow rate(t=2.287,P ＜0.05)and residual urine volume(t=2.513,P＜0.05)obviously improved(P ＜0.05). Conclusion PVP had many advantages such as operated simply and no serious complications.It was a good operation method to treat BPH.

OBJECTIVETo evaluate the efficacy and safety of Yigan Fupi Decoction (YFD) in the treatment of irritable bowel syndrome with diarrhea (IBS-D) patients.

METHODSA randomized controlled clinical trail was carried out in patients with IBS-D. All patients were randomly assigned to the treatment group (58 cases, treated with YFD) and the control group (58 cases, treated with Pinaverium Bromide Tablet). The treatment course was 4 weeks for all patients. The total effective rate, the stool property and state, the quality of life (QOL), and TCM syndrome efficacy were assessed by IBS bowel symptom severity scale (IBS-BSS), IBS defecation state questionnaire (IBS-DSQ), IBS quality of life questionnaire (IBS-QOL), and traditional Chinese medicine pattern curative effect scoring system (TCM-PES) before and after treatment.

RESULTSThere was no statistical difference in the total effective rate between the two groups (82.76% vs. 77.59%, P > 0.05). The treatment group was superior in the total IBS-BSS integral to the control group (P < 0.05). The total effective rate of improving the stool property was better in the treatment group than in the control group (81.03% vs. 72.41%, P < 0.05). Besides, the number of days for emergent defecation among 10 days was less in the treatment group than in the control group (P < 0.05). The improvement of the total IBS-QOL integral and the total integral of TCM syndrome were better in the treatment group than in the control group (P < 0.01). The total effective rate of TCM-PES was better in the treatment group than in the control group (84.48% vs. 70.69%, P < 0.05).

CONCLUSIONYFD was effective in the treatment of IBS-D patients of Gan-qi invading Pi syndrome, and could effectively relieve bowel symptoms, improve the stool property and the defecation frequency, elevate their QOL, and attenuate Gan-qi invading Pi syndrome with favorable safety and compliance.

OBJECTIVE:To extract the feature of Achyranthes bidentata and Cyathula officinalis,and to establish image recog-nition method. METHODS:The microscopic image stitching of A. bidentata and C. officinalis was implemented by MATLAB. The color,invariant moment,stripes and the features of vascular bundle in cross section were extracted. The data was organized into da-ta matrix,and then data matrix was standardized by Zscore function;principal components were analyzed through Princomp func-tion. BP nerve network recognition mode was adopted. RESULTS:The microstructures in the micro images of the samples were kept integrated. The measured data of 27 characteristics were acquired in each group of sample. Through principal component analy-sis,the parameters of 11 main components were selected to establish BP never network. The average recognition rate of BP nerve network was 100% between 2 medicinal material relatives (n=50). CONCLUSIONS:The method can be used for micro-image auto Stitching of Chinese medicinal materials and image recognition of A. bidentata and C. officinalis.

Objective:To investigate the prognosis and outcome of patients with chronic hepatitis C (CHC) related cirrhosis after achieved sustained virologic response (SVR) treated with direct-acting antiviral agent (DAA).Methods:Ninety-five patients diagnosed with CHC related cirrhosis who had complete data in Tianjin Second People′s Hospital from January 2014 to June 2017 were retrospectively followed up. Among them, 72 patients were treated with DAA and all of them achieved SVR, and the other 23 patients did not receive any antiviral therapy. The differences of mortality and incidence of hepatocellular carcinoma (HCC) between DAA treatment group and non-antiviral treatment group were compared. Statistical analysis was performed by independent sample t test, Mann-Whitney U test and chi-square test. Results:At the end of follow-up for three to 71 months, patients in DAA treatment group had a significant improvements in alanine aminotransferase, aspartate aminotransferase, albumin and liver stiffness measurement compared with those before treatment (42(23, 61) U/L vs 18(13, 28) U/L, 54(37, 75) U/L vs 23(18, 28) U/L, 39(33, 42) g/L vs 45(41, 48) g/L, 26(18, 37) kPa vs 15(11, 26) kPa, respectively, Z=-6.005, -7.008, -6.057 and -3.162, respectively, all P<0.01). However, there were no significant differences in incidence of HCC (12%(9/72) vs 17%(4/23)) and mortality (3%(2/72) vs 13%(3/23)) between the DAA treatment group and non-antiviral treatment group (both P>0.05). There was no significant difference of cumulative incidence of HCC in DAA treatment group compared with non-antiviral treatment group ( P=0.609). The age of patients progressed to HCC was older than those without HCC ((60.3±3.6) years vs (54.4±9.9) years, t=-3.948, P<0.01). In subgroup analysis, among the six patients with HCC, four had diabetes, the prevalence of diabetes in the patients without HCC was 17%(7/42); the level of fasting blood glucose (FBG) ((7.3±1.9) mmol/L vs (5.9±1.1) mmol/L) were higher in patients progressed to HCC than those without HCC in DAA treatment group with compensated cirrhosis ( χ2=7.430 and t=-2.442, respectively, both P=0.019). Conclusions:DAA treatment could notably improve liver function and alleviate liver fibrosis, but could not reduce the mortality and incidence of HCC in patients with CHC related cirrhosis significantly. Diabetes and high level FBG may be the risk factors for occurrence of HCC in patients with CHC related compensated cirrhosis.

Objective To investigate the reversal effect of MDR1 and MDR3 gene silencing on resistance of A2780/taxol cells to paclitaxel.Methods shRNA plasmid vector specifically targeting MDR1 and MDR3 genes was transfected into A2780/taxol cells.The early stage cell apoptosis and the effect of intracellular rhodamine 123(Rh123)accumulation were detected by flow cytometry(FCM).The late stage cell apoptosis rate was detected by terminal deoxynucleotidyl transferase(TdT)-mediated deoxyuridine triphosphate(dUTP)nick end labeling(TUNEL).The 50% inhibition concentration(IC_(50))of paclitaxel on A2780/taxol cells was determined by methyl thiazolyl tetrazolium(MTT)assay.MDR1 and MDR3 mRNA were assessed by RT-PCR,and caspase-3 protein was detected by western blot.Results After treatment with MDR1 and MDR3 shRNA plasmid vector,early apoptosis rate of A2780/taxol cells was (20.21?0.56)% and(10.87?1.24)%,respectively.MDR1 and MDR3 shRNA could increase cellular Rh123 accumulation(116.6?8.1 and 98.4?3.8,respectively).The late stage apoptosis rates detected by TUNEL displayed the same tendency as FCM results did.The IC_(50)for paclitaxel of A2780/taxol cells was decreased significantly.The mRNA levels of MDR1 and MDR3 in A2780/taxol cells were decreased by (73.3?0.8)% and(51.6?0.4)% of control,and the reduction of MDR1 and MDR3 mRNA was in a time-dependent manner.The expression of caspase-3 protein of MDR1 and MDR3 shRNA vector transfected group in A2780/taxol cells was significantly increased [(80.8?2.6)% and(72.0?4.7)%, respectively ].Conclusion MDR1 and MDR3 gene silencing could recover sensitivity of A2780/taxol cells to paclitaxel and induce cell apoptosis,thus reversing cell resistance to paclitaxel.

Objective To study the inhibitory effect of verapamil and nicardipine on human scar fibroblast in serum-free culture and to compare the effectness of the two drugs.Methods We used MTT method to detect the effect of two drugs on human scar fibroblast proliferation:adding verapamil and nicardipine with different concentrations in the culture of fibroblasts which were in logarithmic growth phase (150,100,50,10,0μmol/L).After 24,72,and 120 h,we used MTT method to detect the cell proliferation,and converted the absorbance into growth inhibitory ratio.Results Verapamil and nicardipine showed the definite inhibition on the hypertrophic scar fibroblast (HSFB) and keloid fibroblast (KDFB) which were cultured in vitro.There was some difference in the action feature.In the earlier period,the effect of verapamil was powerful than that of nicardipine.With time,the effect did not reinforce.When fibroblast had been cultured for three to five days,the inhibition became weak.But nicardipine showed lasting inhibition on fibroblast proliferation.Conclusion Combination of verapamil with nicardipine may be a valuable method in the treatment of scar.

OBJECTIVETo observe the clinical effect of traditional Chinese medicine Bushen Houxue (BSHX) method combined with ultrasound-guided follicle aspiration (MFA) in treating refractory polycystic ovary syndrome (PCOS).

METHODSForty-four patients with PCOS were randomly assigned to two groups by randomizing digital table, 20 in the observation group and 24 in the control group. MFA was performed on both groups, and the decoction of BSHX, which consisted of dodder seed 20 g, prepared rehmannia root 10 g, mulberry mistletoe 20 g, epimedium 15 g, psoralea fruit 10 g, solomonseal rhizome 10 g, honeylocust thorn 15 g, peach kernel 10 g, pleione bulbocodioides 10 g, red sage root 20 g, and licorice root 6 g, was given to the observation group one dose every day for 14 days every menstrual cycle. Changes of follicle stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) were determined before and after MFA. The impacts on quantity of HMG used, number of sinus follicle, mature follicle, incidence of ovarian hyperstimulating syndrome (OHSS), luteinized unrupture follicular syndrome (LUFS) and pregnance rate were also observed.

RESULTSMFA had been performed for 42 cycles in the observation group and 56 cycles in the control group. Levels of T, LH and LH/FSH ratio markedly reduced after aspiration, showing significant difference as compared with those of before treatment in both groups (P < 0.01), and difference of LH/FSH between groups was of statistical significance (P <0.01). In the observation group, 18 patients (90.0%) had their sinus follicle decreased to < 10 after MFA, while in the control group, it reached to <10 in 22 patients (91.70%), all were different to those before treatment (P <0.01). In the observation group, the quantity of HMG used for promoting ovulation was (585.0 +/- 195.0) IU, number of mature follicle at the day of HCG injection was 1.1 +/- 0.3, while in the control group, the corresponding data were (1470.0 +/- 532.5) IU and 3.1 +/- 1.4, all with significant difference between groups (P <0.01). None of OHSS and 1 case of LUFS occurred in the former group, while 1 mild OHSS and 2 LUFS in the latter. After ovulation promoting therapy and in the 3-month secutive follow-up period, pregnancy was found in 8 out of the 18 patients in the observation group (one twins and 7 single), with the pregnancy rate of 44.4%; while in the control group, 7 in 22 (2 twins and 5 single) was found, the pregnancy rate being 31.8%.

CONCLUSIONBSHX method combined with MFA is a safe and effective treatment for refractory PCOS, with few trauma. The combined usage of Chinese herbal medicine could significantly reduce dosage of HMG used for promoting follicle and the production of multiple mature follicles, thus to avoid the risk of OHSS.
