30%, older or senior recipient, diabetes mellitus, high level blood lipid, re transplantation, DGF, impaired liver function, perioperative infection etc. The follow up period was at least one year. The end points of observation included graft and recipient survival rates, acute rejection, and reversal rate after immunosuppressive drugs bolus, side affects of CsA and FK506 and infection rates in the tow groups. Results The one year patients/grafts survival rate in FK506 and CsA groups was 100% / 100% and 93.3% / 86.7% respectively, the incidence of acute rejection was 14.3% and 16.7% respectively, and reversal rate after immunosuppressive drugs bolus was 100% and 60% respectively. The side effects of FK506 were milder than those of CsA. Conclusion FK506 is the first choice for the renal transplantation recipients with high risk factors.

Objective To discuss the health education modes in order to promote the effect of health education for TURP(transurethral resection of prostate)patients and their family members.Methods A total of 380 cases after TURP were divided into the observation group and the control group at random with 190 cases in each group.The discharge instruction for the patients and their family members in the observation group was in the form of health education prescription,while the discharge instruction for the control group was in the form of oral instruction.The awareness rate of disease-related knowledge and incidence of complication were compared between the two groups. Results The awareness rate of disease-related knowledge in the observation group was higher,and incidence of complications was lower than that of the control group.Conclusions The application of health education prescription in the discharge instruction for the patients after TURP can guarantee the effectiveness of health education,simultaneously decrease the incurrence of complications and improve the life quality of patients.

Objective To investigate the curative effects of fluvastatin and its anti-inflammation mechanism in early diabetic nephropathy (EDN).Methods 140 patients with EDN were randomly divided into two groups,the control group (n=70) and the treated group (n=70).The control group received conventional therapy,while the treated group was added oral 40 microgram of fluvastatin every night.Compare the UAER,Scr and CRP 3,6 and 9 months later respectively.Results UAER and Scr had been decreased more significantly and quickly(three months earlier) in treated group than in control group. CRP had been decreased significantly in treated group,while no significant decrease had been found in control group during the follow-up of nine months.Furthermore,similar results were also obtained in those EDN with normolipidemia when further analyzed.Conclusion Fluvastatin can ameliorate microalbuminuria and improve renal function by its anti-inflammation effect by decreasing CRP,which is independent of its lowering lipidemia effect.

OBJECTIVE To search for the correlative factors among nurses with leukcopenia who occupationally contacted with chemotherapeutic agents,so as to increase their occupational protecting level.METHODS Totally 1232 nurses who occupationally contacted with chemotherapeutic agents from 24 hospitals were investigated by a stratified sampling method.The factors leading to leukopenia were surveyed and analyzed.RESULTS The leukopeuia was prominently correlated with five factors,namely nurses' protective knowledge,protective manipulation scoring,protective condition,exposure index and kinds of agents.CONCLUSIONS Low occupational protecting level can lead to leukopenia.A supporting system based on the occupational health and safety management must be established to insure the clinical nurses' health level.

BACKGROUND:Medical polyethylene glycol berberine is a biomaterial against tissue adhesion, with anti-inflammatory effects, which can prevent scar formation and reduce local inflammation. OBJECTIVE:To observe the clinical efficacy of medical polyethylene glycol berberinevia shoulder joint injections on subacromial impingement syndrome. METHODS:Forty patients with subacromial impingement syndrome I, II were voluntarily divided into two groups: biomaterial group (n=20), single intra-articular injection of 3 mL medical polyethylene glycol berberine; conservative treatment group (n=20), single subacromial space closed treatment of betamethasone combined with lidocaine hydrochloride folowed by oral administration of celecoxib 200 mg once, twice a day, totaly for 1 week. Patients were folowed up clinicaly for visual analog scale scores, range of motion of the shoulder and the American Shoulder and Elbow Surgeons scores. RESULTS AND CONCLUSION:Both of two groups had a great improvement in visual analog scale scores, range of motion of the shoulder and the American Shoulder and Elbow Surgeons scores after treatment (P< 0.05), and these scores were improved more significantly in the biomaterial group than the conservative treatment group at 2 weeks, 4 weeks, 3 months, 6 months after treatment (P < 0.001). These findings indicate that the intra-articular injection of medical polyethylene glycol berberine for subacromial impingement syndrome can effectively aleviate shoulder pain, improve shoulder mobility, and promote functional recovery of the shoulder.

Objective: To develop a molecular screening test for genetic defects on hearing loss related genes has significant impacts on early identification of hereditary hearing loss and genetic susceptibility to aminoglycoside ototoxicity. Early identification of pre-lingual hearing loss is very important for patient's language development, academic achievement, and social skill. Two common mutations, the 235delC in GJB2 gene and the mutation A1555G in mitochondrial DNA, are included in the newly developed screening panel for Chinese population. Methods: A molecular genetic assay, based on fluorescent labeled multiplex PCR and automatic DNA fragment analyzing techniques, was developed to detect both mutations simultaneously. Results: This assay was able to detect both mutations from patient's samples, and pooled DNA tests, as well as suitable to detect mutation from the DNA extracted from dried blood spot and buccal swab. Conclusion: This assay could be a useful tool for newborn screening and carrier screening for the hereditary hearing loss for the Chinese population.

Objective:To explore the correlation between early inflammation indicators and the severity of coronavirus disease 2019 (COVID-19).Methods:A retrospective study was conducted. Patients with COVID-19 admitted to Wenzhou Central Hospital from January 17 to February 14, 2020 were enrolled. The general information, chest CT before admission, the first laboratory parameters and chest CT within 24 hours after admission were collected. Patients were followed up for 30 days after the first onset of dyspnea or pulmonary imaging showed that the lesions progressed more than 50% within 24 to 48 hours (according to the criteria for severe cases) as the study endpoint. According to the endpoint, the patients were divided into two groups: mild type/common type group and severe/critical group, and the differences in general information and inflammation index of the two groups were compared. Logistic regression was used to analyze the inflammation index and the severity of COVID-19. Receiver operating characteristic (ROC) curve was draw to evaluate the predictive value of early inflammation indicators for severe/critical in patients with COVID-19.Results:A total of 140 patients with COVID-19 were included, 74 males and 66 females; the average age was (45±14) years old; 6 cases (4.3%) of mild type, 107 cases (76.4%) of common type, and 22 cases (15.7%) of severe type, 5 cases (3.6%) were critical. There were significantly differences in ages (years old: 43±13 vs. 57±13), the proportion of patients with one chronic disease (17.7% vs. 55.6%), C-reactive protein [CRP (mg/L): 7.3 (2.3, 21.0) vs. 40.1 (18.8, 62.6)], lymphocyte count [LYM (×10 9/L): 1.3 (1.0, 1.8) vs. 0.8 (0.7, 1.1)], the neutrophil/lymphocyte ratio [NLR: 2.1 (1.6, 3.0) vs. 3.1 (2.2, 8.8)] and multilobularinltration, hypo-lymphocytosis, bacterial coinfection, smoking history, hyper-tension and age [MuLBSTA score: 5.0 (3.0, 5.0) vs. 5.0 (5.0, 7.0)] between mild/common group and severe/critical group (all P < 0.05). Univariate Logistic regression analysis showed that CRP, NLR, MuLBSTA score, age, and whether chronic diseases were associated with the severity of COVID-19 [odds ratio ( OR) and 95% confidence interval (95% CI) were 1.037 (1.020-1.055), 1.374 (1.123-1.680), 1.574 (1.296-1.911), 1.082 (1.042-1.125), 6.393 (2.551-16.023), respectively, all P < 0.01]. Further multivariate Logistic regression analysis showed that CRP and MuLBSTA score were risk factors for the development of COVID-19 to severe/critical cases [OR and 95% CI were 1.024 (1.002-1.048) and 1.321 (1.027-1.699) respectively, both P < 0.05]. ROC curve analysis showed that the area under the curve for CRP and MuLBSTA score to predict severe/critical cases were both 0.818, and the best cut-off points were 27.4 mg/L and 6.0 points, respectively. Conclusion:CRP and MuLBSTA score are related to the severity of COVID-19, and may have good independent predictive ability for the development of severe/critical illness.

Aim To explore the effects and mechanism of ginsenoside-Rg1 on SK-N-SH cells treated with chronic morphine and naloxone-precipitated withdrawal. Methods Cells were pretreated with ginsenoside-Rg1 1,2,4,8,16,32 ?mol?L-1 for 24 h,then incubated for 24 h with morphine ( 100 ?mol?L-1 ) . MTT colorimetr was used to study the effects of ginsenoside-Rg1 on the multiplication of the cells treated with chro-nic morphine. After stimulated by the same concentra-tion of morphine,cells were added with different concentrations of Rg1 1,2,4 ?mol?L -1 for 24 h before stimulated with 10 ?mol?L -1 NAL. Fuorospectrophotometry RT-PCR and Western blot techniques were used to detect the effects of ginsenoside-Rg1 on the [Ca2+ ]i,CaMKⅡ ? mRNA and protein expression of the SK-N-SH cells treated with chronic morphine and naloxone-precipitated withdrawal. Results ① Compared with control group,morphine significantly inhibited cell multiplication and resulted in calcium overload,and the expression of CaMKⅡ-? mRNA and protein noticeably increased ( P

Specimens of skin, skeletal muscle, adipose tissue, brain, peripheral nerve and catilage were taken from 6 cadavers (divided into 2 groups) perfused and embalmed with formalin. 90 pieces of the above-mentioned tissues were taken in different times and the paraffin sections were stained by routine HE. Electron microscopic observation was made from some skin and skeletal muscle specimens, and histochemical methods were used to demonstrate DNA, RNA, keratin(-SH, -SS), fatty acids and calcium in some skin materials. Loyez stain method for myelin sheath was applied to some brain and nerve sections.1. Skin tissue: In both group A and B, 83.3% and 78.9% of skin materials were appraised as grade I and II (excellent and good) respectively. The morphological changes appeared mainly as karyopyknosis of the epidermal cells and shrinkage of the secretory part of the sweat glands. Most of the skin tissues of the corpses perfused 3～4 hrs after death were well preserved, only 8.3% being in grade Ⅲ (moderate). On the other hand, 43% of skin materials taken from those perfused 30 hrs after death were in grade Ⅲ. Ultrastructurally, the shape of the epidermal cells and their adhensions still remained intact, but karyopyknosis or chromolysis and autolysis of most of the cytoplasmic membraneous structures were found. In those cadavers preserved for less than one year, there was no evidence of progressive changes in microscopic and submicroscopic structures of the skin. The tonofillaments and desmosomes were still kept well in those specimens preserved for many years, and their presence may be the cause of maintaining cell integrity. Histochemically, mercapto-reaction of keratin was kept stable and found to be well shown even in old samples of skin, but the disulfide reaction usually showed marked fading with time, probably due to exofolition of the stratum corneum. However, this reaction was well shown in the hairs and not weakened for many years.2. Fat tissue: Hydrolysis of lipid substances of subcutancous fat and sebaceous gland, as shown by the presence of fatty acid, was found in the corpses preserved even as short as half a year.3. Skeletal muscle: The preservation state of the skeletal muscle was also dependent on the complete perfusion in time. The structure of the muscle fibers was generally worse preserved than that of the skin as shown in severe myolysis. Since stagnation of the small blood vessels frequently accompanied myolysis, obstruction of microcirculation which prevented the permeation of fomalin into the muscle tissues may be the cause of rapid myolysis. The ultrastructural changes of the muscle fibers were the same as those of the epidermal cells. In all specimens even as old as 30 years, two types of myofillaments were well preserved, and bands could be seen distinctly.4. Nervous tissue: The brain tissues were well preserved in those corpses that were perfused shortly after death, but the peripheral nerves usually showed severe autolysis, obviously it is due to the same reasons as those for myolysis.5. Cartilage: The structural changes of cartilage after death were slow and all specimens of cartilage were well preserved.
