Objective To analyze the 5-year survival rate,causes of death and prognostic indicators of systemic lupus erythematosus (SLE).Methods A retrospective analysis was performed on 243 newly diagnosed SLE patients who Were admitted into our hospital from 1998 to 2005.The clinical features and serologic data were studied.Survival rate of SLE patients over time was studied by the Kaplan-Meier method,and prognostic indicators of mortality were studied by Cox proportional hazards models.Results The 1-,3- and 5-yr survival rate was 96%,94% and 91%,respectively.Renal failure and infection were the main causes of death,followed by lupus encephalotmthy and pulmonary hypertension.Cox regression analysis revealed that lupus nephritis and lupus encephalopathy at the diagnosis were independent risk determinants for mortality.However,age,sex,low C3 level,positive anti-dsDNA antibody,hematological abnormalities,lupus lung involvement and heart damages at diagnosis and immunosuppressant treatment had no strong association with survival.Conclusion Early diagnosis,control of SLE organ damage and infection prevention are critical to improve survival of SLE patients.

Objective: To investigate the effect of ginsenoside Rg3 combined with TRAIL on the apoptosis of lung cancer H358 cells and its possible mechanism. Methods: After the completion of cell culture, H538 cells were treated with TRAIL (0, 50, 100, 200 ng/ ml ) or Rg3 (0, 25, 50, 100 μmol/L) for 48 h, and the cells were grouped according to different treatments, namely control group, 50 μmol/LRg3 group, 100 ng/ml TRAILgroup and 50 μmol/LRg3+100 ng/ml TRAILgroup. The effects of Rg3 and/or TRAILon the proliferation of H358 cells were detected by MTT assay. The effects of Rg3 and/or TRAIL on the morphological changes of H358 cells were observed by DAPI staining. Theapoptosis of H358 cells in each group was detected by flow cytometry. The effects of Rg3 and/or TRAIL on the expressions of death receptor 5 (DR5) and caspase-8 in H358 cells were detected by WB. Results: Compared with the other groups, the proliferation of lung cancer H358 cells was significantly inhibited, while the apoptosis was significantly elevated in the 50 μmol/LRg3+100 ng/ml TRAILgroup (P<0.05).After color developing, cells in 50 μmol/LRg3+100 ng/ml TRAILgroup had nuclear shrinkage, chromatin condensation, increased fluorescence intensity, and late morphological changes such as saturation fragmentation. Compared with the other groups, the expression levels of DR5 and caspase-3 ,8 in the cells of 50 μmol/L Rg3+100 ng/ml TRAIL group were significantly increased (P<0.05). Conclusion: Ginsenoside Rg3 combined with TRAIL can synergistically inhibit the proliferation and induce apoptosis of lung cancer H358 cells. The mechanism may be related to the up-regulation of DR5 and caspase-8 by ginsenoside Rg3.

Objective To investigate the relation between anormalities of fetal abdominal great vessels and heterotaxy, the clinical significance of screening fetal heterotaxy by the abnormalities of fetal abdominal great vessels. Methods 6532 fetuses from our hospital were scanned and the fetuses with abdominal great vessels abnormalities were included. Parameters of fetal growth, abdominal great vessels and anatomical survey were detected. Results Forty-five cases (0.7%) of fetal abdominal great vessels abnormalities were detected prenatally. Forty-two cases were confirmed postnatally, including 35 cases of heterotaxy syndrome and 7 cases of situs inversus totalis and 3 cases missed. The incidences of the abnormal fetus,heterotaxy syndrome and situs inversus totalis of the fetuses with abnormal abdominal great vessels were higher than that of the fetuses with normal abdominal great vessels, the differences were statistically significant( P＜ 0.001). The incidence of both type Ⅰ and type Ⅱ of the heterotaxy syndrome were significantly higher than that of type Ⅳ (P＜0.001). There was a high incidence of left isomerism in abnormal type Ⅰ and of right isomerism in abnormal type Ⅱ , the differences were statistically significant (P＜ 0.001). Conclusions Abnormal great vessels abnormalities have strong relations to heterotaxy and situs inversus which can be used as effective and simple indicator in screening heterotaxy syndrome.

To determine the relevance between MDCT features and anatomic-pathological basis of lymphoid neoplasm in cervico-thoracic junctional region, we performed a retrospective analysis of 69 patients with lymphoid neoplasm (lymphoma: 41 patients; metastatic tumor: 28 patients) involving the cervico-thoracic junctional region for MDCT features and distribution of lesions. The relevance between MDCT features and the anatomic-pathological basis in this region were evaluated. Among all the 41 patients with lymphoma, 29 with NHL (70.7%), 12 with HD (29.3%). The lymphomatous lymphadenopathy mainly located in superficial lateral cervix (51.2%, 21/41) ,deep jugular chain (65.9%, 27/41), supraclavicular fossa (75.6%, 31/41), paratrachea space in anterior mediastinum (46.3%, 19/41), around aortic arch (56.1%, 23/41), aortopulmonary window (53.7%, 22/41), upper anterior mediastinum (41.5%, 17/41), subcarinal space (26.8%, 11/41) and paraesophageal space (17.1%, 7/41). 28 patients had metastatic lymphoid tumor. The primary tumor were nasopharynx tumor (5 patients), thyroid cancer (7 patients), lung cancer (10 patients), and esophageal cancer (6 patients). Most metastasis took stage by stage in the way of lymphatic return, but a minority of cases migrated jumpily. The main metastatic sites were: beside jugular chain (82.1%), supraclavicular fossa (75%), paratracheal in anterior mediastinum (60.7%), upper anterior mediastinum (64.3%), beside aortic arch (35.7%), aortopulmonary window (39.2%), and paraesophageal space (28.6%). So lymphoid neoplasms in cervico-thoracic junctional region were involving both lower cervix and upper thorax simultaneously. The MDCT features and main distribution of lesions correlated with the anatomic-pathological characteristics in this region.

Objective To explore the effect of low-frequency electroacupuncture (EA) on neuropathic pain induced by spinal nerve injury and its underlying mechanism.Methods Thirty-two male Sprague-Dawley rats were randomly divided into a normal group,a sham spared nerve injury (SNI) group,an SNI group and an SNI+EA group,each of 8.The rats in the SNI and SNI+EA groups were given SNI surgery,while those of the sham-SNI group only had the sciatic nerve and its branches exposed without any lesion.EA at 2 Hz was applied over the ipsilateral Zusanli and Kunlun acupoints daily for 14 days after the surgery.The ipsilateral paw withdrawal threshold (PWT) was measured,along with protein kinase A (PKA) levels in the dorsal horn of the spinal cord,calcitonin gene-related peptide (CGRP) and substance P (SP) levels along with transient receptor potential V1 (TRPV1).Results Compared to the normal group,the SNI groups all showed significant decreases in their PWTs on the affected side and significant increases in PKA,TRPV1,CGRP and substance P on the affected side.Compared to SNI group,the average ipsilateral PWT in the SNI+EA group increased significantly after EA treatment,while PKA levels,TRPV1,CGRP levels and SP expression all decreased significantly.Conclusion Electroacupuncture at low frequency can effectively relieve neuropathic pain,perhaps through down-regulation of PKA in the spinal cord and by decreasing pain hypersensitivity related to CGRP and SP.

Objective:To explore the effect of nursing intervention based on the theory of anxiety ratification combined with progressive dominant content in patients with generalized anxiety disorder (GAD) .Methods:From January 2020 to January 2021, convenience sampling was used to select 103 GAD patients admitted to the First Affiliated Hospital of Wenzhou Medical University as the research object. The patients were divided into the observation group ( n=52) and the control group ( n=51) by random number table method. The control group carried out routine nursing, and the observation group conducted the nursing based on the theory of anxiety ratification combined with progressive dominant content on the basis of the control group. The Medical Coping Modes Questionnaire (MCMQ) and the World Health Organization Quality of Life-BREF (WHOQOL-BREF) were used to evaluate the intervention effect. Results:There were no significant differences in MCMQ and WHOQOL-BREF scores between the two groups before intervention ( P>0.05) . After the intervention, the WHOQOL-BREF score and the confrontation dimension score in the MCMQ of the observation group were higher than those of the control group, and the avoidance and resignation dimension scores in the MCMQ were lower than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Nursing intervention based on the theory of anxiety ratification combined with progressive dominant content can effectively guide GAD patients to adopt a positive coping style to face the disease and improve the quality of life of patients, which is worthy of clinical application.

Objective To investigate the prevalence and pattern of androgenetic alopecia (AGA) in Shanghai through a community-based survey. Methods A cluster sampling survey was done among the residents in Beixinjing Community, Changning District, Shanghai. All the subjects were asked to fill a questionnaire to provide their general information, including sex, age, native place, physical status, life habit, family history, etc. The diagnosis of AGA was made by dermatologists. To determine the pattern of hair loss,Norwood-Hamilton classification system and Ludwig classification system were used for male AGA and female AGA, respectively. All the data were statistically analyzed by EpiData and SPSS11.5 software. Results Totally, 7056 subjects completed the questionnaire, including 3519 males and 3537 females, and the response rate was 72.5%. AGA was diagnosed in 809 patients, consisting of 701 males aging from 19 to 91 years (mean 64.16±11.9 years) and 108 females aging from 35 to 91 years (mean 70.46±18.89 years). The standardized prevalence (SP) was 9.47% in total, 15.73% in males and 2.73% in females; the difference was significant between males and females (χ2=356.00, P<0.001). A family history of AGA was observed in 52.7% of all subjects including 391 (55.78%) males and 35 (32.41%) females. Type Ⅲ vertex involvement was the most common type in men aging from 20 to 70 years old, and type Ⅵ in those over 70 years old. Grade Ⅰ and Ⅱ predominated in female AGA. Conclusions The results of this survey indicate that the prevalence of AGA is remarkably higher in men than that in women. Furthermore, the prevalence is steadily increased with advancing age in Shanghai.

BACKGROUND/OBJECTIVES: Activating brown adipose tissue (BAT) and browning of white adipose tissue (WAT) can protect against obesity and obesity-related metabolic conditions.Cryptotanshinone (CT) regulates lipid metabolism and significantly ameliorates insulin resistance. Adenosine-5'-monophosphate (AMP)-activated protein kinase (AMPK), a receptor for cellular energy metabolism, is believed to regulate brown fat activity in humans.MATERIALS/METHODS: The in vivo study included high-fat-fed obese mice administered orally 200/400 mg/kg/d CT. They were evaluated through weight measurement, the intraperitoneal glucose tolerance test (IPGTT), intraperitoneal insulin tolerance test (IPITT), cold stimulation test, serum lipid (total cholesterol, triglycerides, and low-density lipoprotein) measurement, hematoxylin and eosin staining, and immunohistochemistry.Furthermore, the in vitro study investigated primary adipose mesenchymal stem cells (MSCs) with incubation of CT and AMPK agonists (acadesine)/inhibitor (Compound C).Cells were evaluated using Oil Red O staining, Alizarin red staining, flow cytometry, and immunofluorescence staining to identify and observe the osteogenic versus adipogenic differentiation. Quantitative real-time polymerase chain reaction and the Western blot were used to observe related gene expression. RESULTS: In the diet-induced obesity mouse model mice CT suppressed body weight, food intake, glucose levels in the IPGTT and IPTT, serum lipids, the volume of adipose tissue, and increased thermogenesis, uncoupling protein 1, and the AMPK pathway expression. In the in vitro study, CT prevented the formation of lipid droplets from MSCs while activating brown genes and the AMPK pathway. AMPK activator enhanced CT’s effects, while the AMPK inhibitor reversed the effects of CT. CONCLUSION CT promotes adipose tissue browning to increase body thermogenesis and reduce obesity by activating the AMPK pathway. This study provides an experimental foundation for the use of CT in obesity treatment.
