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.

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.

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.

Objective To observe the analgesia effects of nitrous oxide inhalation in childbearing. Method Respectively estimate the labor time,delivery type,degrees of labor pain, fetal distress and postpartum hemorrhage condition between analgesia group of 86 cases and control group of 45 cases. Result Compared to control group, the painful extent of delivery process in analgesia group was obvious lightened and childbearing time was decreased. Conclusion BZ Analgesia effects of nitrous oxide inhalation is positive in childbearing and has great value of clinical applying in obstetrics.

Objective To analyze the curative effects of total knee arthroplasty(TKA)for severe genu varus combined with flexion deformity.Methods The clinical data of 25 patients(36 knees),who had undergone TKA for severe genu varus combined with flexion deformity from January 2005 to October 2010,were retrospectively analyzed.There were 7 males and 18 females,aged from 55 to 80 years(average 70.5 years).The primary diseases were osteoarthritis in 22 cases and rheumatoid arthritis in 3 cases.HSS knee score was used before and after the operation to assess the efficacy of the TKA.Results All of the patients were followed up for 4 to 9 years(average 6 years).The degree of flexion deformity was reduced from (21 ±63)°to(1.1 ±2.3)°;the degree of the varus decreased from(210 ±4.8)°to(175.6 ±2.1)°;range of motion of the knee joint increased from(70.5 ±20.5)°to(115.1 ±5.3)°;knee score augmen-ted from(33.2 ±10.5)to(90.7 ±8.5);function score added from(35.5 ±14.2)to(85.6 ±10.5);there were 21 cases(8 knees)rated as excellent,2(3 knees)as good and 2(3 knees)as fair,and the excel-lent and good rate was 86%.Most of the patients had normal force line of the knee joint,but 2 patients re-mained varus deformity of 5°~10°.Conclusion Satisfying outcome can be achieved by TKA in treating severe genu varus combined with flexion deformity of the knee.

OBJECTIVE To investigate the effect of pranlukast(Pran) on learning and memory impairment and neuroinflammatory and apoptotic response in streptozocin(STZ)-induced type 1 diabetic mice. METHODS Male ICR mice were injected through the tail vein with STZ(150 mg·kg-1)to induce the type 1 diabetes model. Diabetic mice were administered orally with Pran. After 4 consecutive weeks of administration,the escape latency in hidden platform trials,number of platform crossings and time spent in the target quadrant of mice were assessed by the Morris water maze(MWM)test. Western blot was used to detect the proteins of cysteinyl-leukotrienes receptor-1(CysLT1R)and pro-inflammatory factors,nuclear factor-κB p65 subunit(NF-κB p65),interleukin-1β(IL-1β),tumor necrosis factor-α(TNF-α),and cleaved caspase 3,Bax and Bcl-2 in the hippocampus and prefrontal cortex of diabetic mice. We also determined fasting blood glucose,serum insulin and lipids such as triglyceride,total cholesterol,high density lipoprotein cholesterol,and low density lipoprotein cholesterol. RESULTS The data of the MWM test showed that untreated diabetic mice displayed a higher escape latency in hidden platform trials(P<0.05),and a smaller number of platform crossings(P<0.05)as well as shorter per?centage of time spent in the target quadrant(P<0.05). The data of Western blotting showed that treat?ment with Pran 0.6 and 1.2 mg·kg-1 significantly reduced the levels of CysLT1R,nuclear NF-κB p65, IL-1βand TNF-α,cleaved caspase 3,and the ratio of Bax and Bcl-2 in the hippocampus and prefrontal cortex of diabetic mice(P<0.05). However,Pran did not improve the fasting blood glucose,serum insulin or lipid metabolism disorder in diabetic mice. CONCLUSION Pran improves memory impairment and nerve injury in STZ-induced type 1 diabetic mice.

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.
