Risk monitoring of new Chinese patent anti-hepatoma drugs is tracking recognized risks and residual risks, identifying emerging risk and ensure the implementation of the plan, estimating the process of reducing effectiveness. The paper is mainly through understanding the status of Chinese patent anti-hepatoma drugs, the content, characteristic and analysis method of dynamic risk monitoring, and then select the risk control indicators, collect risk information. Finally, puts forward the thought of anti-hepatoma drugs listed evaluation in our country, and try to establish the model of dynamic risk management of anti-hepatoma drugs.

Traditional Chinese ancient prescriptions have been used for treatment of liver cancer for a long history and the scientific and rational compatibility is a great wealth for modern research and development (R&D) of new drugs. The research and development of new drugs are often accompanied with a large investment, a long cycle and a high risk, especially for the anti-tumor drugs R&D which are facing more risks and lower successful rate. In this research, the regularity of compatibility of drugs was analyzed from 124 anti-hepatoma ancient prescriptions by computer program. The results can offer help to the R&D of anti-hepatoma new drugs and reduce the risk of drug screening. In addition, we surveyed 22 companies in this field from six provinces such as Beijing, Shanghai, Tianjin and so on and obtained 240 risk assessment questionaires. Then we used qualitative analysis method to interpret the greatest impacts for the risks in the process of R&D, production and sales of anti-hepatoma new drugs. The study provides a basis for anti-liver cancer drugs R&D researchers, who can take effective measures to reduce the R&D risks and improve successful rate.

OBJECTIVE:
To evaluate the clinical effects and characteristics of combined transperineal and transpubic urethroplasty for patients with complex pelvic fracture urethral distraction defect (PFUDD).
METHODS:
We retrospectively reviewed the clinical data of 17 male patients with complex posterior PFUDD from January 2010 to December 2019. The complications included urethrorectal fistulas in 2 patients (11.8%), urethroperineal fistula in 1 patient (5.9%). Ten patients had undergone previous treatments: dilatation in 3 patients (17.6%), internal urethrotomy in 1 patient, failed urethroplasty in 6 patients (35.3%), of whom 2 patients had two times of failed urethroplasties. All the patients were performed with urethroplasty by combined transperineal and transpubic approach with removing the entire pubic bone followed by the anastomosis.
RESULTS:
The mean age of the patients included in this study was 35.5 (range: 21-62) years. The mean length of stricture was 5.5 (range: 4.5-7.0) cm, the mean follow-up was 27 (range: 7-110) months, the mean time of operation was 190 (range: 150-260) min, the mean evaluated blood loss was 460 (range: 200-1 200) mL. There were 5 patients who needed blood transfusion intraoperatively or postoperatively. Wound infection was seen in 4 out of 17 patients and thrombosis of lower extremities in 1 out of 17 patients. The last follow-up showed that the mean postoperative maximum urinary flow rate was 22.7 (range: 15.5-40.7) mL/s. After removing the catheter, one patient presented with decreased urinary flow and symptoms of urinary infection. Cystoscopy showed the recurrent anastomotic stricture, which was cured by internal urethrotomy. In our series, the success rate of the combined transperineal and transpubic urethroplasty was 94.1% (16/17).
CONCLUSION
Combined transperineal and transpubic urtheroplasty can achieve a tension free anastomosis after removing the entire wedge of pubis in some patients with complex PFUDD. However, this procedure should be completed in a regional referral hospital due to the complexity of the operation and the high percentage of complications.

OBJECTIVETo investigate the risk factors of lung cancer in Tianjin and to provide evidence for further monitor there of.
METHODSA case-control study involving interviews with 193 new cases and 259 controls aged 30 - 76 years was carried out. Structured questionnaires were used to collect information on general condition, living environment, living style, disease and family history, etc. Logistic regression model univariate and multivariate analysis were used to pick out the significant lung cancer risk factors.
RESULTSBy monovariate analysis, risk factors such as smoking, passive smoking, drinking, history of malignancy in family and occupation were found. By multivariate analysis, smoking, passive smoking, higher body mass index (BMI) and average income and living space per capita ten years earlier were ascertained, their operations research (OR) values were 3.302, 1.193, 1.003, 1.067 and 0.913.
CONCLUSIONSmoking and passive smoking are independent risk factors of lung cancer. Monthly income per person and living space per person 10 years earlier are associated with elevated risk of lung cancer. Higher body mass index has protective effects on lung cancer risk.

The present study aims to investigate the lignan constituents from Sambucus williamsii and their proliferation effects on osteoblast-like UMR106 cells. Seven compounds were isolated and purified by macroporous resin D101, silica gel, Sephadex LH-20, Toyopearl HW-40, ODS column chromatographies and Preparative HPLC(C-18). Their structures were elucidated by spectroscopic methods as threo-guaiacylglycerol-beta-0-4'-conifery ether (1), lirioresinol A (2), 1-hydroxypinoresinol (3), 5-methoxybalanophonin (4), balanophonin (5), 5-methoxy-trans-dihydrodehydrodiconiferyl alcohol (6), and p-hydroxybenzaldehyde (7). Compounds 3-7 were obtained from this genus for the first time. The proliferation effects of all isolated compounds on osteoblast-like UMR106 cells were determined. Compounds 1-7 (1 x 10(-12)-1 x 10(-7) mol x L(-1)) increased UMR106 cell proliferation to some extent.

Objective To explore the value of the morphological examination of intrapapillary capillary loop (IPCL) in diagnosis of gastroesophageal reflux disease (GERD) and nursing intervention. Methods 20NERD, 20 erosive esophagi (EE) and 10 healthy volunteers were enrolled in this study, they were assessed with 24 hour ambulatory esophageal pH monitoring and pattern of IPCL which observed by magnifying endoscopy in narrow band imaging (NBI) mode, combined with nursing intervention at the same time. Results Patients receives endoscopic examination successfully. The positive rate of 24 hour ambulatory esophageal pH monitoring was 55% and 90% in the NERD patients and the EE patients, the healthy volunteers were negative. NERD patients were statistically lower than EE patients (P < 0. 05), magnifying endoscopy in narrow band imaging (NBI). Esophageal IPCL showed the regular curl type and small spiral type under the magnifying endoscopy,85.0% sharp of esophageal IPCL in NERD group and 100% in EF group was type Ⅱ, but it still regularly arranged, there was statistically significant difference (X2 = 19.61,30. 00, P < 0. 05). Conclusions The specific morphological changes of IPCL are useful to the endoscopic diagnosis of GERD. High quality nursing intervention is important to endoscopy.
