OBJECTIVE:To provide reference for small interfering ribonucleic acid (SiRNA) R&D and registration in China. METHODS:The situation of SiRNA R&D at home and abroad were introduced,and problems encountered in the evaluation and approval process were summed up to put forward suggestions. RESULTS & CONCLUSIONS:SiRNA has developed slowly in Chi-na,with a gap of 5-10 years at least compared with foreign developed countries. The registration category of SiRNA is not clear;applicants lack of guidance documents;production workshop which meet requirement is in shortage;the efficiency of drug registra-tion allows of no optimism. It is recommended that pharmaceutical registration departments carry out the pilot reform for SiRNA registration,publish SiRNA registration guide,relax regulations for IND gradually,encourage applicants to participate in the inter-national multicenter clinical trials in order to improve the efficiency of SiRNA evaluation and approval efficiency.

Objective:To fast detect hypotensive drugs illegally added to the flower buds of Panax notoginseng. Methods:A laser Raman spectrometer was used to detect several chemical drugs added to the flower buds of Panax notoginseng, and the spectrum was qualitatively analyzed. Results:Raman spectroscopy could detect chemical antihypertensive drugs added to the flower buds of Panax notoginseng, and the test results were in accordance with those of the traditional method. Conclusion: Raman spectroscopy can be used for the determination of illegal additives in the flower buds of Panax notoginseng.

Pulmonary interstitial fibrosis (PIF) is a common complication of connective tissue disease (CTD). The patients with PIF usually manifest with intensive dry cough, progressive dyspnea aggravated by activities, and even weight loss and very fatigued. In this paper, we have applied the traditional methods of "invigorating qi for ascending" and "strengthening earth to generate metal" with modif ied Shenxian decoction for treating CTD combined with PIF to support healthy energy, ascend thoracic qi, and ascend both qi of lung and spleen. We have observed Shenxian decoction could enhance body immune system, benefit the repair of damaged lung tissues, improve microcirculations, and treat both branch and root of body, which has been giving patients prominent effects.

Diabetic retinopathy ( DR ) is one of the most serious microvascular complications of diabetes. It also is a world's major causes of blind eye diseases. Although the injection of anti - vascular endothelial growth factor intraocular drug is becoming a hotspot of current research. Pan retinal photocoagulation (PRP) remains the effective and economical treatment for DR. As a destructive treatment, PRP will inevitably cause some changes on the normal morphology and function of the retinal and cornea. Currently, with the development of the optical coherence tomography, confocal microscopy and other auxiliary examination, we have more accurate and objective research to better understand the laser-neural tissue interaction. This may help us to protect the patient's visual function more efficiently.

The incidence rate of erectile dysfunction (ED) is reportedly as high as 30-90% after radical prostatectomy for prostate cancer, which seriously affects the patients' quality of life. Penile rehabilitation is defined as the use of any drug or device at or after radical prostatectomy to maximize erectile function recovery. A variety of treatment options are available for post-prostatectomy ED patients, including oral phosphodiesterase 5 inhibitors (PDE5I) , intracorporal injections, vacuum erection device, and penile prosthesis. This article presents an overview of the currently used methods for the drug treatment and penile rehabilitation of the ED patients after radical prostatectomy. It seems proper to recommend daily use of a vacuum erection device plus oral PDE5I in the early postoperative period. For those who fail to respond to this therapy, intraurethral alprostadil, intracorporal injections, or a penile prosthesis could be considered.

Objective:To investigate the clinical efficacy of every 3-week regimen of oxaliplatin (OXA) plus 5-fluorouracil (5-FU)/leucovorin(CF)as postoperative adjuvant chemotherapy for colorectal cancer.Methods:Ninety eight patients with stage Ⅱ to stage Ⅲ colorectal cancer received every 3-week OXA plus 5-FU/CF adjuvant chemotherapy for six cycles after resection surgery. All the patients received a complete reexamination every 3 months after the end of adjuvant chemotherapy. The disease-free survival period and 1- and 2-year disease-free survival rates were observed.Results:The total 2-year disease-free survival rate was 74.5%. It was 87.0% for stageⅡpatients and 63.5% for stage Ⅲ patients. The main adverse reaction included peripheral neurotoxicity, neutropenia and diarrhea at grades Ⅰ to Ⅱ. Grades Ⅲ to Ⅳ adverse reactions occurred rarely.Conclusion:The every 3-week OXA combined with 5-FU/CF adjuvant chemotherapy regimen had definite efficacy and good tolerance, which was a rational choice of postoperative adjuvant chemotherapy for colorectal cancer.

Objective To explore the possibility of repairing face rhombus defect after resection of pathological tissues on the special regions. Methods After rhombus resection of a pathological tissues on the special regions of the face, using four triangular flaps at the any sides of the defect to stagger suturing each other and to constitute peculiar "M" flap repairing defect in 26 patients (12 males and 14 females). Results The flaps were all survived. No straight line scars were seen at the repairing regions and no scars contraction for the face contour was occurred. Conclusion This is a simple and effective operation procedure that can be used for rhombus defect of the special regions of the face.

It presented in detail the acquisition of Qingdao Wan Jie Hospital by the Affiliated Hospital of Medical College Qingdao University, describing the operational mechanisms in organizational setup, specialty setup, personnel management, logistic management, hospital culture and branding of the newly acquired section. It also summarized the achievements in medical resources reorganization and advantages complementary without government investment in a fast and low-cost manner. It is demonstrated that hospital acquisitions are in line with the medical reform, as they expand the service coverage of public hospitals, and extend medical service to the communities and lower levels, thus enhancing hospitals' impact and reach to integrate medical resources in a short timeframe.
