Nonalcoholic fatty liver disease (NAFLD) is a major public health issue worldwide. Immunoglobulin G (IgG) N-glycans are associated with risk factors for NAFLD, such as obesity and diabetes. A cross-sectional study involving 500 Han Chinese adults recruited from a community in Beijing was carried out to explore the association between IgG N-glycans and NAFLD. IgG N-glycosylation was significantly associated with NAFLD, with the disease showing a negative correlation with galactosylation (GP14, GP14n, and G2n), positive correlation with fucosylation (FBG2n/G2n), and positive correlation with bisecting N-acetylglucosamine (GlcNAc) [FBG2n/FG2n and FBG2n/(FG2n+FBG2n)], after controlling age, gender, and prevalence of obesity, type 2 diabetes mellitus, hypertension, and hyperlipidemia. In other words, the present study showed a possible association between NAFLD and the loss of galactose and elevations of fucose and bisecting GlcNAc. Aberrant IgG glycosylation might therefore be a potential biomarker for the primary or secondary prevention of NAFLD.

The distribution, yield and sample information data of Pinus massoniana was obtained by document literature and sample investigation. Based on sample data from 12 provinces including 414 sample plots and environment factors in China,the distribution regionalization of P. massoniana was predicted by using Maxent and spatial analysis function of ArcGIS. The results showed that the northernmost distribution of P. massoniana was 33.5 degrees north latitude, and it mainly distributed in the southeast in China. Based on plant age, plant height, yield per plant and other growth index from 414 sample plots, combined vegetation form and other data, the growth regionalization of P. massoniana was carried out by using SPSS and related functions of ArcGIS. The results showed that Fujian, Guizhou and Guangxi had a lager distribution area of P. massoniana, meanwhile, it had a relatively higher yield of fresh pine needles. The relational model between environmental factors and shikimic acid,and procyanidin, and the total lignans was constructed by using SPSS regression analysis method. Then the spatial calculation function of ArcGIS was used tocarry out the quality regionalization of P. massoniana based on the relational model. The results showed that east of Sichuan, Guizhou, Chongqing had a good pine needles quality. Based on the distribution, growth and quality regionalization, the production suitability regionalization of P. massoniana was carried out. The results showed that the optimal planting base region mainly distributed in east of Sichuan, middle and east of Guizhou, and east of Guangxi.
4. Preparation of nimesulide solid dispersion by hot melt extrusion technology
Chinese Pharmaceutical Journal 2013;48(3):185-190
OBJECTIVE: To improve the in vitro dissolution of nimesulide by preparing nimesulide solid dispersion with hot melt extrusion (HME) technology. METHODS: Using PVP-VA64, PVP K30 or PVA-PEG (Kollicoat IR) as hydrophilic carrier, nimesulide solid dispersion was prepared by hot melt extrusion and characterized by drug dissolution, DSC, XRD and FTIR. RESULTS: Nimesulide exhibited rapid in vitro dissolution from the solid dispersion using PVP-VA64 as carrier. The cumulative release rate was 81% in 10 min, much faster than its physical mixture (only 37% in 1 h). The results of DSC and FTIR showed that nimesulide was amorphously dispersed in the carrier. CONCLUSION: Hot melt extrusion technology is suitable for preparing nimesulide-PVP-VA64 solid dispersion, which can significantly increase drug dissolution.

BACKGROUNDThe role of gastro-protecting agents on symptomatic chronic gastritis is unclear. This multicenter, open, randomized trial was designed to compare the comprehensive effects of gefarnate with sucralfate on erosive gastritis with dyspeptic symptoms.
METHODSTotally 253 dyspepsia patients confirmed with erosive gastritis were enrolled from six centers in China. They randomly received either daily 300 mg gefarnate or 3 g sucralfate for six weeks. The primary endpoint was the effective rate of both treatments on endoscopic erosion at week six.
RESULTSGefarnate showed an effective rate of 72% and 67% on endoscopic score and dyspeptic symptom release, which is statistically higher than sucralfate (40.1% and 39.3%, P < 0.001, intension-to-treat). For histological improvement, gefarnate showed both effective in decreasing mucosal chronic inflammation (57.7% vs. 24.8%, P < 0.001, intension-to-treat) and active inflammation (36.4% vs. 23.1%, P < 0.05, intension-to-treat) than the control. A significant increase of prostaglandins and decrease of myeloperoxidase in mucosa were observed in gefarnate group. Severity of erosion is non-relevant to symptoms but Helicobacter pylori (H. pylori) status does affect the outcome of therapy.
CONCLUSIONSGefarnate demonstrates an effective outcome on the mucosal inflammation in patients with chronic erosive gastritis. Endoscopic and inflammation score should be the major indexes used in gastritis-related trials.

OBJECTIVETo examine how the thymidine phosphorylase (TP) gene expression is upregulated by interferon-alpha (IFN-alpha) in human hepatocellular carcinoma SMMC-7721 cells.
METHODSTP mRNA levels were determined by RT-PCR. Whether the JAK-STAT cascade mediates IFN-alpha-induced TP mRNA expression was studied by pretreatment with Janus Kinase (JAK) inhibitor, AG-490. Effects of IFN-alpha on TP mRNA stability were detected with additional actinomycin D.
RESULTSThe expression of TP mRNA was induced by IFN-alpha in a dose- and time-dependent manner in SMMC-7721 (human hepatocellular carcinoma) cells. TP mRNA levels rose at 8 h, reached the peak value at 12 h, and remained at a high level up to 72 h in SMMC-7721 cells treated with IFN-alpha 10000 U/ml. IFN-alpha at a dose of 5000 or 10000 U/ml up-regulated TP expression about 3 fold compared with that of non-treated cells (P < 0.05). Induction of TP mRNA expression by IFN-alpha was significantly inhibited in SMMC-7721 cells by pretreatment with AG-490, in comparison with that treated with IFN-alpha alone. Pretreatment of SMMC-7721 cells with IFN-alpha 10000 U/ml for 24 h caused a substantial stabilization of TP mRNA, with a half-live of 35.8 h, compared with 8.5 hr in the control SMMC-7721 cells.
CONCLUSIONIFN-alpha at certain doses upregulates TP mRNA expression via both JAK-STAT transcriptional activation and post-transcriptional mRNA stabilization in human hepatocellular carcinoma SMMC-7721 cells.

OBJECTIVETo investigate the plasma lipid levels in a national representative sample of subjects and to determine the prevalence of dyslipidemia in the Chinese population.
METHODSPlasma lipid profile was analyzed using the data obtained during the Chinese national nutrition and health survey (CNHS) in 2002 which involved 14 252 participants at the age of 18 years or older.
RESULTSThe mean levels of total cholesterol (TC), triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) in the participants were 3.81 mmol/L, 1.10 mmol/L, and 1.30 mmol/L, respectively. In the groups of participants at the age of 18-44 years, 45-59 years, and over 60 years the mean TC level was 3.70 mmol/L, 4.09 mmol/L and 4.21 mmol/L, respectively, and the mean TG level was 07 mmol/L, 1.21 mmol/L, 1.20 mmol/L, 1.29 mmol/L, 1.33 mmol/L, and 1.33 mmol/L, respectively. The prevalence of dyslipidemia in Chinese adults was 18.6% and 22.2% in males and 15.9% in females. Dyslipidemia prevalence was higher in urban districts than in rural areas (21.0% vs. 17.7%). The prevalence of hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterol was 2.9%, 11.9%, and 7.4% respectively among the participants.
CONCLUSIONDyslipidemia has become one of the important health risk factors in the Chinese population. There is no significantly difference in the prevalence of dyslipidemia between the groups of participants at the age of 45-59 years and over 60 years. This study provides important lipid profile data for policy making and guideline development for the prevention of dyslipidemia in the Chinese population.

OBJECTIVETo study the distribution of prevalence on hypercholesterolemia and borderline high cholesterol of Chinese residents aged 20 years and above.
METHODSTo detect the total fasting plasma cholesterol in 48 299 subjects among 20 year-olds and above.
RESULTSWithin a certain age range, the prevalence of both hypercholesterolemia and borderline high cholesterol increased with age, but there was a decreasing trend after 60-years of age in some regions. The prevalence of hypercholesterolemia increased to 12.53% in over 70 year-olds group from 1.36% in urban 20-year-olds, and increased to 5.15% from 60-year-olds group comparing to 0.98% of the 20-year-old group in rural areas. When comparing to the 20-year-old age group, the prevalence of borderline high cholesterol of the 70 age group in urban and rural increased by 4.4 and 4.2 times, respectively. The prevalence of hypercholesterolemia in each age group in urban were higher than that of in rural areas. In Rural I, it was higher than that of in Rural II , Rural III and Rural IV. The prevalence rates of both hypercholesterolemia and borderline high cholesterol of the males in the less than 50 year-olds group were higher than that in females, which was quite different from the group older than 50 years of age. As to borderline high cholesterol, similar result was also noticed.
CONCLUSIONWithin a certain age range, there was a trend that the prevalence of both hypercholesterolemia and borderline high cholesterol increased with age and related to regions which were classified by economic status. A distinct difference between males and females also existed.
