ObjectiveIn order to explore the changes of chemical constituents in Plantaginis Semen before and after stir-frying， ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF/MS^E） was used to rapidly identify and semi-quantitatively analyze the differential components in Plantaginis Semen processed at different stir-frying time. MethodWaters ACQUITY UPLC BEH C₁₈ column （2.1 mm×100 mm， 1.8 μm） was employed with the mobile phase of 0.1% formic acid aqueous solution （A）-acetonitrile （B） for gradient elution （0-1 min， 5%-10%B； 1-2 min， 10%-15%B； 2-10 min， 15%-20%B； 10-12 min， 20%-40%B； 12-13 min， 40%-100%B； 13-14 min， 100%-5%B； 14-15 min， 5%B）， the flow rate was 0.3 mL·min^-1， the column temperature was 40 ℃， and the injection volume was 3 μL. Electrospray ionization （ESI） was applied for mass spectrometric analysis under positive and negative ion modes， and the scanning range was m/z 50-1 500. MarkerLynx 4.1 software was used to find the differential compounds， and the intensity of each ion peak in samples with different stir-frying time was compared to study the content variations of these compounds. ResultA total of 20 components with potential significant differences were found， among which 17 were identified and 3 were unknown， mainly including phenylethanoid glycosides， iridoid glycosides， alkaloids and others. After processing， the peak intensities of 7 compounds， such as sucrose， geniposidic acid， verbascoside and plantagoguanidinic acid A， in Plantaginis Semen decreased. The peak intensities of orobanchoside， dianthoside and plantain D increased first and then decreased during the stir-frying process. The peak intensities of 10 compounds （decaffeoylacteoside， calceolarioside A， isoacteoside， etc.） increased， and 9 of them were newly generated components. ConclusionThe content and composition of the chemical components in Plantaginis Semen changed significantly after stir-frying， which may be related to the reduction of laxative effect and the enhancement of antidiarrheal and diuretic activities of Plantaginis Semen after stir-frying.

OBJECTIVE: To assess the efficacy of the combined treatment with electroacupuncture (EA) and intradermal needling on simple obesity and explore its underlying effect mechanism. METHODS: A total number of 116 patients with simple obesity were randomized into an observation group (58 cases, 3 cases dropped off and 2 cases removed) and a control group (58 cases, 4 cases dropped off and 1 cases removed). Patients in the control group received EA at Zhongwan (CV 12), Quchi (LI 11), Zusanli (ST 36), Pishu (BL 20), Weishu (BL 21), etc., for 30 min each time. On the base of the intervention as the control group, the patients in the observation group received the intradermal needling at Tianshu (ST 25), Daheng (SP 15), Zusanli (ST 36), Shangjuxu (ST 37), Quchi (LI 11), Pishu (BL 20) and Weishu (BL 21). In each group, the intervention was given once every two days, 3 times a week, consecutively for 3 months. Before and after treatment, the obesity indexes (body mass [BW], body mass index [BMI], body fat percentage [F%], adiposity [A] and waist circumference [WC]), the serum intestinal lymphatic function-related factors (vascular endothelial growth factor C [VEGF-C], delta-like ligand 4 [DLL4], adrenomedullin [ADM]), blood lipid (total cholesterol [TC], triglyceride [TG] and low density lipoprotein-cholesterol [LDL-C]), and fasting plasma glucose (FPG), fasting insulin (FINS) and insulin resistance index (HOMA-IR) were observed in the patients of both groups; and the efficacy was assessed. RESULTS: The effective rate was 88.7% (47/53) in the observation group, higher than 71.7% (38/53) in the control group (P<0.05). After treatment, except FPG in the control group, BW, BMI, F%, A, WC, and the concentrations of serum VEGF-C, DLL4 and ADM, as well as TC, TG, LDL-C, FBG, FINS and HOMA-IR were all reduced compared with those before treatment in both groups (P<0.05). The reduction ranges of BW, BMI, F%, A, WC, and the concentrations of serum VEGF-C, DLL4 and ADM, and TC, LDL-C, FINS and HOMA-IR in the observation group were all larger than those in the control group (P<0.05). CONCLUSION Electroacupuncture combined with intradermal needling can reduce body weight and lipid, and improve insulin resistance in treatment of simple obesity, which is achieved probably through inhibiting lymphangiogenesis and promoting lymphatic endothelial permeability.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Traditional Chinese medicines(TCMs) have certain limitations in the clinical research design in their post-marketing evaluation, so that randomized controlled programs cannot be strictly implemented in some studies, while the objective performance criteria is a reasonable external controlled research method that has been gradually recognized at home and abroad in recent years in addition to randomized controlled trial(RCT) method. It is more mature in medical devices, surgery and other research fields, but there is no relevant report in the field of post-marketing evaluation of Chinese patent medicines. In this paper, the application prospect of the objective performance criteria and the problems were discussed in the field of post-marketing evaluation of TCM. The characteristics of as TCM are more consistent with the scope of the objective performance criteria, the application of the objective performance criteria in post-marketing evaluation of Chinese patent medicines, especially in single arm research, can break through the limitations of existing conventional clinical research methods, and improve the level of evidence, with good feasibility and advantages. However, in the application process, we should pay attention to the key issues such as the selection of index, research population, follow-up period and the reference selection, to ensure the quality of research. This research group has carried out some exploration and practice in the field of post-marketing evaluation of TCM injections by using single arm combined with the objective performance criteria, hoping to establish the key technology in this field, and provide certain research and design reference for the secondary development of Chinese patent medicines.

Background::Mounting evidence, consistent with our previous study, showed that γ-aminobutyric acid type A receptor (GABAAR) played an indispensable role in airway inflammation and mucus hypersecretion in asthma. Monocyte chemotactic protein-inducing protein 1 (MCPIP1) was a key negative regulator of inflammation. Recent studies showed that inflammation was largely suppressed by enhanced MCPIP1 expression in many inflammatory diseases. However, the role and potential mechanism of MCPIP1 in airway inflammation and mucus hypersecretion in asthma were still not well studied. This study was to explore the role of MCPIP1 in asthmatic airway inflammation and mucus hypersecretion in both mice and BEAS-2B cells, and its potential mechanism.Methods::In vivo, mice were sensitized and challenged by ovalbumin (OVA) to induce asthma. Airway inflammation and mucus secretion were analyzed. In vitro, BEAS-2B cells were chosen. Interleukin (IL)-13 was used to stimulate inflammation and mucus hypersecretion in cells. MCPIP1 Lentiviral vector (LA-MCPIP1) and plasmid-MCPIP1 were used to up-regulate MCPIP1 in lung and cells, respectively. MCP-1, thymic stromal lymphopoietin (TSLP), mucin 5AC (MUC5AC), MCPIP1, and GABAARβ2 expressions were measured in both lung and BEAS-2B cells. Immunofluorescence staining was performed to observe the expression of GABAARβ2 in cells. Results::MCPIP1 was up-regulated by LA-MCPIP1 ( P < 0.001) and plasmid-MCPIP1 ( P < 0.001) in lung and cells, respectively. OVA-induced airway inflammation and mucus hypersecretion, OVA-enhanced MCP-1, TSLP, MUC5AC, and GABAARβ2 expressions, and OVA-reduced MCPIP1 were significantly blunted by LA-MCPIP1 in mice (all P < 0.001). IL-13-enhanced MCP-1, TSLP, MUC5AC, and GABAARβ2 expressions, and IL-13-reduced MCPIP1 were markedly abrogated by plasmid-MCPIP1 in BEAS-2B cells (all P < 0.001). Conclusion::The results of this study suggested that OVA and IL-13-induced airway inflammation and mucus hypersecretion were negatively regulated by MCPIP1 in both lung and BEAS-2B cells, involving GABAAR signaling pathway.

To analyze the regularity in combined medication with Xiyanping injection (Xiyanping for short) in the real world by as- sociation rules. Totally 5 822 patients using Xiyanping injection was collected from the 18 Class III Grade I hospitals nationwide to study the combined medication information of the patient with lung infection and make the analysis by using association rules and Apriori. According to the results, major drugs combined with Xiyanping in treatment of lung infection included compound amino acid, inosine, coenzyme A, cytidine triphosphate, vitamin C. Common drugs combined with Xiyanping can be divided into 5 categories: nutrition support therapy (vitamin C, compound amino acid) , coenzymes (coenzyme A, cytidine triphosphate, inosine), expectorants and antiasthmatics (ambroxol, salbutamol, doxofylline), hormones (dexamethasone, budesonide), antibiotics (mainly cefminox). The main combined medicines mostly conformed to the regularity for drugs treating lung infection. In addition, there were two most common medical combination models: the model for Xiyanping combined a single medicine is Xiyanping + nutrition support therapy, while the model for Xiyanping combined two or more than two medicines is Xiyanping + nutrition support therapy + coenzyme. Pharmacologically, Xiyanping is mostly combined with western medicines with similar pharmacological effects to substitute or supplement the antibiotic effect in treating lung infection. However, further studies shall be conducted for the safety and rationality of the combined medication based on clinical practices, in order to provide reference for clinical medication.

OBJECTIVETo explore the clinical roles of Jiawei Shentong Zhuyu Decoction (JSZD) in preventing the occurrence of failed back surgery syndrome (FBSS), and to observe its effect on serum tumor necrosis factor-alpha (TNF-alpha).

METHODSTotally 100 patients prepared for surgical operation due to lumbar intervertebral disc herniation were randomly assigned to the treatment group and the control group according to random number table, 50 cases in each group. Patients in the treatment group additionally took JSZD, one dose per day, taken in two portions, once in the morning and once in the evening. Those in the control group took Celecoxib Capsule (200 mg each time, once per day) and Mecobalamin Tablet (0.5 mg each time, 3 times per day). They only took Mecobalamin Tablet from the 11th day. All patients were treated for 30 days. Japanese Orthopaedic Association (JOA) score was performed before treatment, at week 1, after treatment, at 6 months of followed-ups, and at 12 months of followed-ups. And the levels of TNF-alpha in the peripheral blood were observed before treatment and at one month after treatment.

RESULTSTotally 93 patients completed the followed-up study. The JOA scores were improved after treatment, at 6 and 12 months of followed-ups (P < 0.05, P < 0.01). The JOA score at 6 months of followed-ups was superior in the treatment group to that of the control group (P < 0.05). Five patients (accounting for 10.6%) suffered from FBSS in the treatment group, while 9 (accounting for 19.6%) suffered from FBSS in the control group. The treatment group was superior to the control group (P < 0.05). The TNFalpha level was improved after treatment in the two groups. Of them, the improvement of TNF-alpha in the treatment group was better than that of the control group (P < 0.05).

CONCLUSIONThe application of JSZD was effective for preventing the occurrence of FBSS, and improved the serum TNF-alpha level.
