Objective:To explore the protective effect and the mechanism of Danggui Shaoyaosan（DSS） on angiotensin Ⅱ （AngⅡ）/transient receptor potential cation channel 6 （TRPC6） pathway in nephrotic syndrome （NS） rats. Method:In animal experiments， doxorubicin （4 mg·kg^-1 for the 1^st week and 2 mg·kg^-1 for the 2^nd week） was injected twice to the tail vein of rats to induce NS model in 160 rats， which were then randomly divided into model group （normal saline）， losartan group （30 mg·kg^-1·d^-1）， and low-（4.3 g·kg^-1·d^-1）， medium-（8.6 g·kg^-1·d^-1）， and high-dose （17.2 g·kg^-1·d^-1） DSS groups. Besides， a normal group was also set. After intervention for four weeks， ultrastructure changes of the kidney were identified by transmission electron microscopy （TEM）. The 24-hour urine protein was detected by kits. Radioimmunoassay was used to detect the content of AngⅡ and Calcineurin （CaN） in plasma. Western blot was used to detect the protein expression of TRPC6， angiotensin Ⅱ type 1 receptor （AT1R）， podocyte slit diaphragm-specific protein （Nephrin）， and cysteine-aspartic acid protease-3 （Caspase-3） in the renal cortex. Immunohistochemistry was used to detect the expression of TRPC6 and AT1R in the slit diaphragm. In cell experiments， AngⅡ stimulated MPC5 podocytes. The cells were randomly divided into a normal group， an AngⅡ group， an AngⅡ+SAR7334 （TRPC6-specific inhibitor） group， an AngⅡ+5%DSS group， an AngⅡ+10%DSS group， and an AngⅡ+15%DSS group. Western blot was used to detect the protein expression of TRPC6， AT1R， Nephrin， and Caspase-3 in podocytes. Result:Compared with the normal group， the model group showed increased 24-hour urine protein content （P<0.01） and AngⅡ and CaN in plasma （P<0.01）， incomplete glomerular structure， the extensive fusion of podocyte process with elevated fusion rate （P<0.01）， increased expression distribution of AT1R and TRPC6 in the renal cortex， and up-regulated protein expression of AT1R， TRPC6， and Caspase-3 in renal tissues （P<0.01）， and reduced Nephrin protein expression （P<0.01）. Compared with model group， the losartan group and the high-dose DSS group exhibited decreased 24-hour urine protein content （P<0.01） and the content of AngⅡ and CaN in plasma （P<0.01）， improved glomerular structure， reduced fusion rate of podocyte process （P<0.01）， diminished expression distribution of TRPC6 and AT1R in the renal cortex， declining protein expression of AT1R， TRPC6 and Caspase-3 in renal tissues （P<0.01）， and elevated Nephrin protein expression （P<0.01）. Additionally， compared with the normal podocytes， AngⅡ-stimulated podocytes showed increased protein expression of AT1R， TRPC6 and Caspase-3 （P<0.01）， and decreased expression of Nephrin （P<0.01）. Compared with the AngⅡ group， the AngⅡ+SAR7334 group displayed reduced protein expression of AT1R， TRPC6， and Caspase-3 （P<0.01） and increased protein expression of Nephrin （P<0.01）. Conclusion:DSS can improve the pathological characteristics of NS presumedly by inhibiting the interaction between AngⅡ and TRPC6 in podocytes and improving the structural integrity of podocytes to repair the damage of glomerular molecular barrier and slow down the progression of NS-induced proteinuria.

BACKGROUND: Psoriasis is a chronic inflammatory skin disease, affecting about 0.6% of the Chinese population. Many patients are not well controlled by conventional treatments, thus there is need for new treatment regimens. In this study, we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis. METHODS: This study was a 52-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 trial. A sub-population of study participants (≥18 years) of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab, or placebo. The co-primary endpoints were psoriasis area severity index (PASI) 75 and Investigator's Global Assessment (IGA) 0/1 at Week 12. RESULTS: A total of 441 Chinese patients were enrolled in this study. Co-primary outcomes were achieved; 300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75 (97.7% and 87.2% vs. 3.7%, respectively; P < 0.001), and IGA 0/1 (82.3% and 69.7% vs. 2.7%; P < 0.001) at Week 12. Treatment efficacy was maintained until Week 52. There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period. CONCLUSION: Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.

BACKGROUNDAtopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD.

METHODSA hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software.

RESULTSA total of 2662 valid questionnaires were collected (1369 male and 1293 female). Of all 2662 patients, 2062 (77.5%) patients had the disease after 12 years old, while only 600 (22.5%) patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months. One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients.

CONCLUSIONLate-onset of eczema or AD is common. The clinical manifestations of AD are heterogeneous. We have proposed Chinese diagnostic criteria for adolescent and adult AD, which are simple and sensitive for diagnosis of adult/adolescent AD.

OBJECTIVETo explore the distribution laws of TCM syndrome types and to analyze the distribution of dynamic blood pressure curve, atherosclerosis, and age in senile hypertension patients.

METHODSTotally 1 131 senile hypertension patients were recruited from 7 provinces and municipal cities. Features of TCM syndromes, classification and distribution curves, and syndrome distribution laws were observed. The distribution curves of dynamic blood pressure, carotid atherosclerosis, and age were compared in each TCM syndrome types.

RESULTSThere were four main syndrome types in 736 cases (56.15%), i.e., excessive accumulation of phlegm-dampness syndrome (210 cases, 16.02%), yin deficiency and hyperactivity of yang syndrome (177 cases, 13.50%), Gan-Shen yin deficiency syndrome (79 cases, 6.03%), and deficiency of qi and yin syndrome (252 cases, 19.22%). Besides, there were two more sub-types, i.e., collateral obstruction by blood stasis syndrome and collateral obstruction by phlegm and stasis. Circadian blood pressure monitor was completed in 211 cases. Of them, abnormal circadian blood pressure occurred in 152 cases (accounting for 72. 38%); yin deficiency and hyperactivity of yang syndrome, excessive accumulation of phlegm-dampness syndrome, deficiency of qi and yin syndrome plus collateral obstruction by blood stasis syndrome were most often seen. Color ultrasound of carotid artery was performed in 660 patients of main syndromes. The incidence was quite higher in those of excessive accumulation of phlegm-dampness syndrome (182 cases, 27. 58%), deficiency of qi and yin syndrome plus collateral obstruction by blood stasis syndrome or collateral obstruction by phlegm and stasis (322 cases, 48.79%). Yin deficiency and hyperactivity of yang syndrome was dominant in patients 60 -79 years old, while deficiency of qi and yin syndrome and Gan-Shen yin deficiency syndrome were dominant in patients older than 80 years.

CONCLUSIONSExcessive accumulation of phlegm-dampness syndrome, yin deficiency and hyperactivity of yang syndrome, Gan-Shen yin deficiency syndrome, and deficiency of qi and yin syndrome were main syndrome types in senile hypertension patients. There was statistical difference in the distribution curves of blood pressure, atherosclerosis, and age of various TCM syndrome types.

To explore the method of explants directly induced bud and establish the tissue culture system of mutiple shoot by means of direct organogenesis, core bud and daughter bulbs (the top of bud stem expanded to form daughter bulb) of T. edulis were used as explants and treated with thidiazuron (TDZ) and 1-naphthlcetic acid (NAA). The results showed that the optimal medium for bud inducted form core bud and daughter bulb were MS + TDZ 2.0 mg x L(-1) + NAA 4.0 mg x L(-1) and MS +TDZ 2.0 mg x L(-1) + NAA 2.0 mg x L(-1) respectively, both of them had a bud induction rate of 72.92%, 79.22%. The optimal medium for cluster buds multiplication was MS + TDZ 0.2 mg x L(-1) + NAA 0.2 mg x L(-1), and proliferation coefficient was 2.23. After proliferation, cluster buds rooting occurred on MS medium with IBA 1.0 mg x L(-1) and the rooting rate was 52.6%, three to five seedlings in each plant. Using core bud and daughter bulb of T. edulis, the optimum medium for adventitious bud directly inducted from daughter bulb, core bud and cluster bud multiplication were screened out and the tissue culture system of multiple shoot by means of direct organogenesis was established.

Objective To compare the clinical characteristics and clinical outcomes in young (≤45 years) female and male coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI). Methods Angiographic and clinical data from 124 premenopausal female patients who underwent elective PCI from April 2004 to February 2008 were compared to age-matched 430 male patients who underwent elective PCI between 2006 and 2007 in our department. All patients were treated according to guidelines and coronary angiography was repeated after 6 months. One year clinical follow-up were performed in all patients. Results Incidences of dyslipidemia, the history of myocardial infarction and smoking were significantly lower in female patients than in male patients (all P < 0.01 ). Left main, left anterior descending and bifurcation lesions were more common while type C lesion and right coronary lesion were less common in young female CAD group compared to young male CAD group (P <0. 01 -0. 05). The average lesion length in female patients was significantly longer than that in male patients [ (20. 36±13.37)mm vs.( 23.04±13.86) mm, P < 0. 05 ]. The in-hospital and follow-up incidences of major adverse cardiac events,stent thrombosis and in-stent restenosis were similar between young female and male CAD patients.Conclusions CAD risk factors were less and vessel lesions were more likely to be found at left main, left anterior descending and bifurcation in young female CAD patients compared to young male CAD patients.The clinical outcomes were similar between young female and male CAD patients.
