China Pharmacy 1991;0(02):-
OBJECTIVE:To prepare the minoxidil gel and to establish a quality control method for the gel.METHODS:Carbopol934was used as the gel base;the content of minoxidil was determined with UV-spectrogram and the stability test was performed.RESULTS:There was a good linearity of calibration curve of minoxidil in range of2~10?g/ml(r=0.9999).The average recovery was99.8%,and RSD was0.67%(n=4).The gel was stable.CONCLUSION:The gel is reasonable in for?mulation,simple and accurate in quality control,as well as satisfactory in stability.

Objective To investigate the significance of DNA ploidy analysis in diagnosis of atypical squamous cell of undetermined significance ( ASCUS).Methods From Jan.2009 to Jul.2011,875 women with ASCUS confirmed by liquid based thin layer cytology technique underwent DNA ploid analysis in Hubei Maternal and Child Health Hospital.Among 294 women underwent high risk HPV detection.All subjective were examined colposcopy directed biopsy at day 3 to 10 after menstruation.Results Among 875 ASCUS cases,553 cases with histologically as chronic cervicitis (63.2%),165 cases with cervical intraepithelial neoplasia (CIN) Ⅰ (18.9% ),45 cases with CIN Ⅱ (5.1%),79 cases with CIN Ⅲ (9.0%) and 33 cases with cervical invasive cancer (3.8%) were confirmed by colposcopy.Totally 532 cases were observed with DNA heteroploid,and 343 were not observed with DNA heteroploid.When DNA heteroploid negative and more than or equal to three ploid were used to predict CIN Ⅱ or more severe cervical diseases,the sensitivity,specificity,positive predictive values and negative predictive values were 98.7% and 90.3%,47.5% and 46.1%,29.1% and 40.8%,99.4% and 92.1%,respectively.The amount of heteroploid cells >2.5c and > 5c among every 100 detected cells in chronic cervicitis and CIN Ⅰ,CIN Ⅱ,CIN Ⅲ and cervix cancer were respectively 2.53 ± 1.99 and 0.10 ±0.07,2.24 ± 1.69 and 0.20 ±0.11,4.10 ± 1.91 and 0.28 ±0.19,7.97 ±7.33 and 1.27 ± 1.23,8.99 ±7.33 and 0.36 ±0.33,there was no statistical difference in amount of heteropolid cells between > 2.5c and > 5c at group of chronic cervicitis and CIN Ⅰ,CIN Ⅲ and cervix cancer (P > 0.05).However,the amount of heteroploid cells at >2.5c and> 5c at group of chronic cervicitis,CINⅠ,CIN Ⅲ and cervical were higher than that of CIN Ⅱ significantly (P <0.05).Among 294 cases with high risk (HR) HPV detection,216 cases were HR-HPV positive,and 78 cases were HR-HPV negative.The pathology result by colposcopy at group of negative heteroploid,heteroploid < 3,or ≥ 3 showed statistical distribution (x2 =115.2775,P < 0.01).ConclusionDNA ploidy analysis can be used for ASCUS diagnosis,which can avoid excessive biopsy under colposcopy,in the mean time,CIN and cervical cancer could decrease missed diagnosis.

Objective To summarize the meticulous nursing experience of indwelling urinary catheter between the children with hypospadias during perioperative. Methods 317 cases of indwelling urethral only in the silicone Foley tube, and without other urinary diversion with hypospadias were retrospectively analyzed, summarized the fine points of nursing, including preoperative children with comprehensive risk assessment, standardized preoperative skin preparation and postoperative protective constraint, effective properly fixed catheter keep the urine drainage unobstructed, close observation of urine drainage characteristics, maintain urine collection system tightness, maintain perineal skin clean and improved extubation nursing method, and do a good job after extubation nursing. Results 266 cases were cured with a cure rate of 83.9%(266/317);the incidence of urine leakage in 42 cases, the incidence rate was 13.2%(42/317); 7 cases of urethral stenosis, the incidence rate was 2.2%(7/317); 2 cases of urethral closing, the incidence was 0.6% (2/317), none of the patients had accidental extubation. Conclusions The meticulous nursing has a better effect in hypospadias patients during the perioperative period and it can reduce the incidence of postoperative complications;shorten the time of hospitalization and alleviate the suffering of children;improve the quality of nursing service, which is worthy of clinical application.

Objective To observe the effect of visible light on apoptosis of cultured human retinal pigment epithelium (RPE) cells. Methods Being the light source,500lx,(2 000?500)lx and (3 400?200)lx cold white light were used. The duration of exposure was 0,6,12 and 24 hours respectively. Apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end labelling, Annexin V flunorescein isothiocyanate/Propidium iodium labelling and flow cytometry. Results Apoptosis and necrosis were found in cultured human RPE cells which were exposed to visible light.(1)A significant increase in apoptotic and necrotic percentages was consistent with a higher light intensity.(2)Apoptosis was the main response to shorter (6 h and 12 h) exposure duration,while necrosis was more pronounced correlated to the prolongation of post exposure culture ( P 500 lx) increases the proportion of apoptosis and necrosis of human RPE cells in vitro.The extent is related to exposure intensity and duration. It demonstrates that the lower intensity and the shorter duration of exposure to light are, the more pronounced apoptotic percentages are observed,otherwise necrosis.

[Objective]To explore the efficacy and results of tibial tubercle osteotomy used in exposure in complicated total knee arthroplasty.[Methods]During the period from Apr.2005 to Apr.2007,the tibial tubercle osteotomy were used in 16 cases of complicated total knee arthroplasty.The mean follow-up time were 20 months(6~26 months).Knee society score(KSS) and radiography were used to evaluate the clinical results.[Results]The mean KSS improved from 46 points preoperatively to 91 points postoperatively.The mean ROM improved to from 53?preoperatively 105?postoperatively.At 3 months after surgery the radiography examines showed all 16 cases had achieved satisfactory healing.The tubercle fragment slided toward proximal 0.7 cm occurred in one case,and finally healed at that position.[Conclusion]Exposure of the knee may be difficult in the total knee arthroplasty,but tibial tubercle osteotomy is a safe and reliable procedure which affords excellent exposure.

Journal of Chinese Physician 2001;0(07):-
Objective To evaluate the effect of various kinds of dyslipidaemia on insulin resistance and pancreatic islet ? cell function in newly diagnosed type 2 diabetic patients. Methods 263 patients with newly diagnosed type 2 diabetes were divided into normal lipidemia group and dyslipidaemia group according to ATPⅢ standard. The dyslipidaemia group included 3 subgroups as the following: high TG group, high TC group, and mix group with high TG and TC. Homeostasis model assessment (HOMA) was applied to estimate insulin resistance (IR) and pancreatic islet ? cell function. Early insulin secretion index (EISI) and area under curve of insulin (AUCI) at all OGTT time points were calculated. Results Incidence of dyslipidaemia in the type 2 diabetic patients was 63%. BMI and WHR were significantly higher in both high TG group and mix group than in normal lipidemia group(P

Alzheimer′s disease(AD)is one of the neurodegenerative diseases.Now it seriously threatens the life of the elderly.The pathogenesis of AD is not clear,thus there is no cure for this disease.The current treatment can′t reverse the pathological change of the disease or prevent the development of the disease,and the symptoms of the AD patients can only be partly improved.In recent years,the application of RNAi technology to the inhibition of the expression of the AD-related genes provides a new method for the treatment of AD.This article mainly introduces the application of the RNAi technology to AD.
