ABSTRACT
Objective To investigate the clinical efficacy of Changqin No. 1 combined with Western therapy for severe traumatic brain injury and its effects on prognosis. Methods Totally 65 cases of severe traumatic brain injury were randomly divided into the treatment group (n=32) and the control group (n=33). The control group was treated with basic Western therapy (dehydration reduction of intracranial pressure, nutrition nerve, scavenging oxygen free radicals, improve cerebral circulation, nutritional support and maintain the internal environment stability, anti-infection, prevention and treatment of complications, hyperbaric oxygen). The treatment group was treated with Changqin No. 1 plus the basis of routine treatment, 1 dosage per day, 2 times stomach tube nasal feeding or blunt, for 14 d. One month after treatment, awake rate, awake time, the incidence of complications and MMSE in both groups were compared. Three months after treatment, the prognosis of two groups were compared by GOS. Results One month after treatment, the awake rate in treatment group was 77.4% (24/31) and 53.1% (17/32) in the control group, with statistical significance (χ2=4.089, P=0.043), and the death rate was 0. The awake time in the treatment group was significantly shorter than that of the control group (t=2.458, P=0.017). The incidence of pulmonary infection in the treatment group was lower than the control group (P=0.001). There was no statistical significance in urinary tract infection, epilepsy, liver and kidney dysfunction rate of the two groups (P>0.05). The number of awake case was 24 in the treatment group and 17 in the control group. The number of normal MMSE cognitive function was 3 in the treatment group and 2 in the control group, and the treatment group was better than the control group (Z=-2.205, P=0.027). Three months after treatment, the good prognosis was 58.08% (18/31) in the treatment group and 28.12%(9/32) in the control group, with statistical significance (χ2=5.763, P=0.016). Conclusion Changqin No. 1 combined with Western basic treatment can help patients with severe traumatic head injury awake early, reduce pulmonary infection complications, and improve the cognitive function of sober patients and improve the prognosis.
ABSTRACT
Objective To explore the association between rs3758539G-803A and rs10882283 T-179G polymorphism of retinol binding protein 4 (RBP4) and rosiglitazone response in Chinese type 2 diabetes mellitus (T2DM) patients.Methods A total of 472 Chinese T2DM patients and 198 healthy subjects were enrolled to identify G-803A and T-179G genotypes using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP ).assay.Forty-two T2DM patients with different G-803A or T-179G genotypes were selected to undergo a 12-week rosiglitazone treatment (4 mg/d).Serum fasting plasma glucose (FPG),postprandial plasma glucose (PPG),fasting serum insulin (FINS),glycated hemoglobin (HbAlc),postprandial serum insulin ( PINS),triglyceride (TG),low-density lipoprotein-cholesterol ( LDL-c),and high-density lipoprotein-cholesterol (HDL-c) were determined before and after the rosiglitazone treatment.Results T2DM patients with RBP4 G-803A GG genotype showed lower TG and LDL-c concentrations compared with that in the GA +AA genotype subjects.T2DM patients with RBP4 T-179G TT genotype showed lower waist-to-hip ratio (WHR),FPG and FINS values compared with that in the TG + GG genotype individuals.Patients with GG genotype of RBP4 G-803A had an enhanced rosiglitazone efficacy on FPG and FINS compared with that in the GA + AA genotype group.Patients with RBP4 T179G TG + GG genotype showed an enhanced rosiglitazone efficacy on HbAlc level compared with that in the TT genotype group.Conclusion RBP4 G-803A and T-179G polymorphism might be associated with the development of T2DM and affect the therapeutic efficacy of rosignitazone in Chinese T2DM patients.
ABSTRACT
Objective To investigate the effect of nicotinamide mononucleotide (NMN) on insulin secretion and gene expressions of pancreatic and duodenal homeobox 1 ( PDX-1 ) and forkhead box-containing protein O-1 ( FoxO1 ),which were important transcription factors for insulin secretion.Methods Insulin secretion level in RIN-m5f cells was detected by rat insulin ELISA detection kit.The mRNA expression levels of PDX-1 and FoxO1 in RIN-m5f cells were analyzed by real-time PCR.The protein expression of PDX-1 was measured by Western blot.Results Insulin secretion levels in RIN-m5f cells treated with repaglinide ( 10 nmol/L) plus NMN ( 100 μnol/L) was significantly higher than those in the blank control,the DMSO control group,and the NMN (50μmol/L) treated group (P ＜0.05 ).The mRNA expression levels of PDX-1 in RIN-m5f cells treated with NMN ( 10,50 and 100 μmol/L) for 36 h were significantly higher than those in the control group (P ＜0.05,P ＜ 0.01,and P ＜ 0.001,respectively).There was marked differences in the mRNA expression levels of PDX-1 among different concentrations of NMN (P ＜0.001 ),but no significant differences in the mRNA expression level of FoxO1 ( P ＞ 0.05).No significant difference was found in the protein expression levels of PDX-1 in RIN-m5f cells treated by NMN (50,100,and 200 μmol/L) for 36 or 48 h compared with the control group (P ＞ 0.05).Conclusion NMN can stimulate insulin secretion and upregulate the mRNA expression of PDX-1 in RIN-m5f cells.
ABSTRACT
Objective To observe the effect of jiaweibugan decoction on VEGF expression of sciatic nerve in experimental diabetic rat and explore the preventive and therapeutic effects of iiaweibugan decoction on peripheral neumpathy in~xperimental diabetic rats.Methotis The diabetic rat model was established by streptozotocin(STZ).The rats were killed on the 4th or 8th week from the beginning of treatment respectively,and VEGF mRNA of sciatic nerve was detected by reverse-transcriptase polymerase chain reaction(RT-PCR).Resuits The results of RT-PCR showed that VEGF expression ofthe model group and treated group on the4th or8th week WaS higherthan that of the normal control group(P＜0.05).Compared with the model group,VEGF expression in the diabetic rats treated byjiaweibugan decoction increased markedly at the end of4th week(P＜0.05),while decreaSed significantly at the end of8th week(P＜0.05).Conclusion Jiaweibugan decoction has a proventive and therapeutic effect on peripheral neumpathy in experimental diabetic rats.
ABSTRACT
Objective To study the effect of Jianweiyuyang(JWYY) granule on gastric ulcer of rats and its effective mechanism. Methods The rat model of gastric ulcer was set up by Okeba's method with some modification, and the expression of vascular endothelial growth factor (VEGF) and platelets-derived growth factor (PDGF) in the gastric ulcer tissues was examined by immunohistochemical method. Results JWYY granule could elevate the expression of both VEGF and PDGF, obviously decrease the ulcer index, increase the thickness of gastric mucosa, and promote the healing of gastric ulcer. Conclusion The results indicated that Jianweiyuyang granule can increase the expression of VEGF and PDGF, which may be one of the mechanism of its promoting the healing of the gastric ulcer.
