AIM: To explore the anti-low-grade-inflammation mechanisms of Shenqi Compound Recipe(SQCR) in GK rats. METHODS: Specefic pathogen free(SPF) GK rats were divided randomly according to blood glucose level into four groups:Model,Ramipril,SQCR low dosage,SQCR high dosage group and normal Wistar rats(normal control group).GK rats were injected N-?-nitrol-L-arginine methyl ester(L-NAME) intra-peritoneally and took high-fat diet and Wistar rats were injected saline intra-peritoneally and took common diet freely,respectively.In the experiment periods,each group was administrated correspondent substance respectively for 32 days.Serum concentrations of C reactive protein(CRP) and adiponectin were determined by ELISA.Adiponectin mRNA expressions in white adiposed tissue were measured by real time reverse transcriptase PCR. RESULTS:Concentrations of CRP all decreased(P

Objective To study the prevalence of intraventficular hemorrhage(IVH)in premature infants using bedside cranial ultrasound scans and to analyze the associated laboratory results.Methods 114 patients admitted between February 2003 and March 2004 were eligible for the study.NAS-2000A 3D ultrasound instrument for bedside ultrasound detection were used.All the premature infants were detected for blood gas analysis,blood cell analysis(red blood cell counting,haemoglobin and haematocrit),prothrombin time (PT),fibrinogen(FIB)and activated partial thromboplastin time(APTT)in the first 24 hours of life.Results There were 34 IVH cases in 114 patients(29.8%).The ineidence of IVH of premature infants below 34 weeks gestation was 43.8%,which was higher than that of infants above 35 weeks gestation.The incidence of IVH of infants whose birth weight were below 1 500 g is 58.8%,which was higher than that of infants whose birth weight were above 1 500 g.The incidence of IVH increased with decreasing gestational age and birth weight.As compared with the values of infants without IVH,HB and HCT of the IVH infants were higher (P＜0.05);PT and APTT of the IVH inrants were longer(P＜0.01);hypoxia,hypercapnia and acidosis were more common in IVH infants(P＜0.05).Conclusion Risk factors such as short gestational age,low birth weight,increased HB and HCT,prolongation of PT and APTT,hypoxia,hypercapnia and acidosis may be associated with the IVH in premature infants.

Objective To observe the effect of mirror therapy on acute stroke dysphagia. Methods 60 patients with dysphagia were randomly divided into treatment group (n=30) and control group (n=30). The control group received routine dysphagia rehabilitation and intermittent oral gastric tube feeding, while the treatment group received mirror therapy in addition. They were assessed with Kubota water-drinking test and swallowing videofluoroscopy 4 weeks after treatment, and the incidence of aspiration were recorded. Results The oral transit time, swallowing reaction time, pharyngeal transit time, laryngeal closure duration improved in the treatment group compared with the control group in swallowing videofluoroscopy (P<0.05). The total effective rate was obviously higher in the treatment group than in the control group (P<0.05), with the lower incidence of aspiration pneumonia (P<0.05). Conclusion Mirror therapy may promote the recovery of swallowing function after acute stroke, and reduce the risk of aspiration.

OBJECTIVETo investigate the clinical features and genetic characteristics of patients with 3-hydroxy-isobutyryl-CoA hydrolase (HIBCH) gene mutations.

METHODThe clinical data of a patient with novel HIBCH mutations were collected, the related literature was searched from China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, National Center for Biotechnology Information and PubMed (up to December 2014) by using search terms" HIBCH", "3-hydroxy-isobutyryl-CoA hydrolase" or "beta-Hydroxyisobutyryl CoA Deacylase Deficiency". The clinical features, neuroimage and treatment of the patients with HIBCH gene mutations were studied.

RESULTThe patient was a girl who was born at term after an uneventful pregnancy to non-consanguineous healthy parents, she was hospitalized at 5 years and 5 months of age because of development delay for 5 years and 5 months and abnormal posture on the left of body for more than 10 days. The family history was unremarkable. Her psychomotor development was significantly delayed. Three times brain MRI between 2. 5 years and 5 years of age revealed bilateral symmetrical lesions in basal ganglia. At the age of 5 years and 5 months, she presented with acute encephalopathy and severe extrapyramidal symptoms preceded by fever. At that time, her brain MRI revealed aggravated lesions in bilateral basal ganglia, new lesions in the midbrain cerebral peduncle and pons, and cerebellar atrophy. The results of biochemical tests were normal. A novel compound heterozygous mutation of HIBCH gene, c. 1027C > G, p. H343D and c. 79-1G > T, splicing, were found in the parent. Further study showed that c. 1027 C > G mutation was inherited from her father and c. 79-1 G > T from her mother. Her symptoms were mitigated after "cocktail" therapy and symptomatic treatment. Repeated brain MRI revealed that the lesion in basal ganglia got better, the lesions in brain stem disappeared. Literature relevant to HIBCH published all around the world was reviewed, no Chinese cases with HIBCH gene mutations had been reported, 6 foreign cases with HIBCH gene mutations were reported. Among them, 5 patients were diagnosed as Leigh-like syndrome, with progressive neurodegenerative course, and symmetrical basal ganglia lesions on brain MRI. Another case was reported in 1982, with developmental delay and various physical malformations without data on his brain MRI. HIBCH gene mutational analysis showed that 4 cases had homozygous mutations, which were c. 950G > A (p. G317E) in two brothers, c. 219 _220insTTGAATAG (p. K73fsX86) and c. 1128_1129insT (p. K377X) respectively. Three of them died before 3 years old. Two cases had compound heterozygous mutations: c. 365A > G (p. Y122C) and IVS2-3C > G (p. R27fsX50); c. 517 + 1G > A and c. 410C > T (p. A137V). They were alive at the time of the report.

CONCLUSIONPatients with HIBCH gene mutation mainly presented as Leigh-like syndrome both in clinical manifestation and in neuroimage. HIBCH gene mutational analysis should be performed on children with Leigh-like syndrome, if the mutations of known genes of Leigh syndrome were negative.

Sulfur fumigation was a traditional maintenance method for traditional Chinese medicines (TCMs). However , as people have paid more and more attentions on the sulfur dioxide residue in the sulfur fumigated TCMs , China has gradually decreased and banned the sulfur fumigation for TCMs . This study adopted organic elemental analysis for the determination of sulfur contents in multiple TCMs . Elemental analysis can give accu-rate results with little sample amount in a short time . Data analysis indicated that the sulfur content of 0.5% can be set as a criterion for the identification of sulfur fumigated TCMs. Sulfur content of ten unknown TCMs were determined by elemental analysis and identified whether the TCMs have been fumigated by sulfur. The devel-oped elemental analysis method can be used as a screening method for rapid identification of TCMs' quality.
