OBJECTIVETo observe the effects of navel-warming therapy on clinical efficacy in patients with yang-deficiency tympanites based on regular treatment of western medication.

METHODSOne hundred and twenty cases of yang-deficiency tympanites were randomly divided into a navel-warming therapy group and a western medication group, sixty cases in each one. The regular treatment of western medicine was applied in the western medication group, including oral administration of antiviral drug and diuretics as well as intravenous drip of hepatic protector. Based on western medicine treatment, the navel-warming therapy was applied in the navel-warming group. A medical cake was laid on Shenque (CV 8), and then a medical cylinder was placed above the medical cake and ignited. The treatment was given once daily. One month was considered as a treatment session in both groups and totally one session was required. The TCM symptom score, B-ultrasound ascites and temporary use of diuretics before and after treatment were observed in both groups; also the efficacy was evaluated.

RESULTSThe total effective rate was 81.7% (49/60) in the navel-warming therapy group, which was superior to 56.7% (34/60) in the western medication group (P < 0.05). After the treatment, the TCM symptom score and ascites were improved in both groups (all P < 0.05), which was more significant in the navel-warming therapy group (all P < 0.05). The temporary use of diuretics was statistically different between the two groups (P < 0.05), indicating the navel-warming therapy group could obviously reduce or stop the use of diuretics.

CONCLUSIONBased on regular treatment of western medication, the navel-warming therapy could significantly improve therapeutic efficacy, effectively relieve clinical symptoms and ease ascites.

A novel method was developed for the rapid determination of multi-indicators in corni fructus by means of near infrared (NIR) spectroscopy. Particle swarm optimization (PSO) based least squares support vector machine was investigated to increase the levels of quality control. The calibration models of moisture, extractum, morroniside and loganin were established using the PSO-LS-SVM algorithm. The performance of PSO-LS-SVM models was compared with partial least squares regression (PLSR) and back propagation artificial neural network (BP-ANN). The calibration and validation results of PSO-LS-SVM were superior to both PLS and BP-ANN. For PSO-LS-SVM models, the correlation coefficients (r) of calibrations were all above 0.942. The optimal prediction results were also achieved by PSO-LS-SVM models with the RMSEP (root mean square error of prediction) and RSEP (relative standard errors of prediction) less than 1.176 and 15.5% respectively. The results suggest that PSO-LS-SVM algorithm has a good model performance and high prediction accuracy. NIR has a potential value for rapid determination of multi-indicators in Corni Fructus.

Objective To evaluate the prognostic value of serial 18F-fluorodeexyglucose (FDG) PET/CT in patients with nasopharyngeal carcinoma (NPC).Methods Thirty-seven NPC patients who had 18F-FDG PET/CT scan before and after external beam intensity-modulated radiotherapy, were studied retrospectively.All patients were followed for five years.Correlation analysis between metabolic tumor volume (MTV)/uptake volume index (UVI) and survival was performed by Kaplan-Meier analysis, Log-rank test and multivariate Cox model.Results The 5-year overall survival (OS) and disease-free survival (DFS) rates were 70.3% (26/37) and 62.2% ( 23/37 ), respectively.Patients with a lower MTV (MTV＜30 cm3) had significantly higher 5-year OS ( 82.6% ( 19/23 ) ) and DFS (73.9% ( 17/23 )) rates than those with a higher MTV (OS:50.0% (7/14),x2 =5.28, P＜0.05; DFS:42.9% (6/14),x2 =4.84, P＜0.05).Patients with a lower UV1 (UVI＜150) had significantly higher 5-year OS( 87.5%( 21/24 )) and DFS (79.2% (19/24)) rates than those with a higher UVI (OS:38.5% (5/13),x2 =10.72, P＜0.01;DFS:30.8% (4/13), x2 =11.04, P＜0.01).Multivariate analysis showed that UVI and metabolic response (MR) were independent predictors of DFS.Conclusions Tumor volume parameters, UVI and MR, are independent prognostic factors for patients with NPC.Patients with a high UVI may benefit from more aggressive treatment.

Objective:To produce rhBMP-4 with bioactivity in E.coli. Methods: The full-length human BMP-4 gene was mutated by PCR without changes in amino acid sequence, then the synthesized gene was cloned into plasmid pET-3c, transducted into BL21(DE)plysS, and induced by adding IPTG to a final concentration of 1.0 mmol/L. The protein product was purified using ion-exchange chromatography method and then renaturated, bioactivity was checked by C2C12 differentiation in vitro and mouse ectopic bone formation in vivo. Results: A 438 bp gene fragment encoding mature peptide of hBMP-4 was cloned , the protein product was mostly in the form of inclusion body, after renaturation, the engineering protein shows better bioactivity. Conclusion:The mutant strategy can enhance the expression of bioactive rhBMP-4 in E.coli expression system.

Glutathione is a tripeptide comprised by L-glutamate, L-cysteine, and glycine, that serves antioxygenation and deintoxication functions within the cell. Recent study has found that glutathione is the main driving force for bile salt-independent bile flow, impaired biliary excretion of glutathione can lead to cholestasis. This review focuses on hepatobiliary transport of glutathione and its role in cholestasis. Based on the evidence of choleretic effect of glutathione, enhancement of biliary excretion of glutathione may be a good strategy for prevention and treatment of cholestasis.

To detect chromosome translocation t(11;18) (q21;q21) and the nuclear expression of bcl-10 in gastrointestinal mucosa-associated lymphoid tissue (MALT) lymphoma in Chinese, a possible API2-MALT fusion transcript specific to t(11; 18) (q21; q21) in tumors from 42 cases of primary gastrointestinal lymphoma (29 cases of low grade MALT lymphoma, 13 cases of transformed MALT lymphoma) and 40 cases of diffuse large B cell lymphoma was examined by means of RT-PCR and proved by DNA-sequencing. Bcl-10 expression was examined by immunohistochemical method. The results showed that t(11;18) (q21;q21) was 14% positive in cases of low grade MALT lymphomas and 46% positive in transformed MALT lymphomas, but none in cases of DLBCL. Bcl-10 nuclear expression was seen 61% in low grade MALT and 69% in transformed MALT lymphoma. It was suggested that t(11;18) (q21;q21) was related to the prognosis and development of highly advanced MALT lymphoma but not relevant to DLBCL. Bcl-10 nuclear expressions were not significantly different between these two groups, which remains to be explained.

OBJECTIVETo explore the relationship between differential activation of mitogen-activated protein kinase (MAPK) signal transduction system and apoptosis in PC12 cells induced by electromagnetic irradiation.

METHODSCultured PC12 cells were exposed to 65 mW/cm(2) electromagnetic wave for 20 min. The PC12 cells apoptosis was detected by flow cytometry 0, 3, 12, 24 h after electromagnetic irradiation. The phosphorylations of ERK1/2, JNK and P38 MAPK were tested by Western-blot.

RESULTSElectromagnetic irradiation induced apoptosis in PC12 cells soon after irradiation. The apoptotic rate of PC12 cells increased to about 23.5% at 3 h. But compared with that at 3 h, there was no significant difference in the apoptotic rate at 12 h (P > 0.05). The apoptotic rate of PC12 cells increased sharply again at 24 h. After exposure to electromagnetic irradiation, the phosphorylations of ERK1/2 and JNK increased significantly. The increased phosphorylation of ERK1/2 lasted for 3 hours, but of JNK lasted for 12 hours, and 24 hours after irradiation. The phosphorylation of both ERK1/2 and JNK were significantly lower than that of control. The phosphorylation of P38 MAPK was always higher after electromagnetic irradiation, and there were two phosphorylation peaks at 3 h and 24 h.

CONCLUSIONThe electromagnetic irradiation can induce the activation of MAPK signal transduction system, and ERK1/2, JNK, P38 MAPK showed differential activation. The differential activation of MAPKs may play an important role in the apoptosis of PC12 cells induced by electromagnetic irradiation.

OBJECTIVETo explore the effects of obesity on the peak level of luteinizing hormone (LH) in the gonadotropin-releasing hormone (GnRH) agonist test and obesity-related hormones in girls with central precocious puberty (CPP).

METHODSThree hundred and thirty-three girls with CPP who underwent the GnRH agonist test between 2012 and 2014 were classified into three groups: normal weight (n=123), overweight (n=108), and obesity (n=102), according to body mass index (BMI). The sexual development indices were compared between the three groups. Twenty girls were randomly selected from each group for evaluation of the serum levels of leptin, sex hormone binding globulin (SHBG), neurokinin B, and kisspeptin. The correlation of BMI with the levels of various hormones was assessed using Pearson correlation analysis.

RESULTSThere was no significant difference in mean age at diagnosis between the three groups; however, the bone age was significantly higher in the overweight and obesity groups than in the normal weight group (P<0.05). The peak level of LH in the GnRH agonist test and SHBG level in the normal weight group were significantly higher than those in the overweight and the obesity groups, while the serum levels of leptin and neurokinin B were significantly lower in the normal weight group than in the overweight and the obesity groups (P<0.05). BMI was negatively correlated with the peak level of LH in the GnRH agonist test and SHBG level (P<0.05), and positively correlated with the levels of leptin and neurokinin B (P<0.05).

CONCLUSIONSThe effects of BMI on the result of the GnRH agonist test and levels of obesity-related hormones should be taken into account in girls with precocious puberty.
