OBJECTIVETo investigate the protective effects of Nourishingyin and Promotingblood flow recipe (NYPBR) on the kidney of diabetic rat.

METHODSD rats were divided into 3 groups at random: control group, diabetes group and NYPBR group. The latter two groups were injected intraperitoneally with streptozotocin to induce diabetes model. Rats in NYPBR group were fed NYPBR solution (3 g x d(-1)), with dose equivalent to the clinical use in the patients. Rats in the other groups were fed equivalent water. 10 weeks after diabetes was induced, the inducible nitric oxide synthase (iNOS) mRNA expression in the renal cortex was detected by RT-PCR, and its protein content by Western blotting. Immunohistochemistry was used to detect the formation of nitrotyrosine (NT), a specific marker of peroxynitrite (ONOO-). The morphological changes of renal cortex were observed under optical microscope. Superoxide dismutase (SOD) and malondialdehyde (MDA) in renal cortex, blood glucose, 24 h urine protein content and creatinine clearance rate in different groups were detected.

RESULTCompared with control group, the iNOS mRNA expression (0.90 +/- 0.10) and its protein content (43.00 +/- 6.08), and NT content (87.23 +/- 5.94) increased significantly in diabetes group, in accord with the pathological changes of renal cortex and renal dysfunction. NYPBR can attenuate the pathological alterations.

CONCLUSIONNYPBR could decrease iNOS mRNA expression and its protein content, and reducing the overformation of ONOO-, thus protecting the kidney of diabetic rat from injury.

OBJECTIVETo develop a new platform for genotyping human papillomavirus (HPV) and to investigate its effect in clinical application.

METHODSA pair of common primers of 18 HPV subtypes for PCR, was designed in HPV conservative L1 region. Genotyping probes for detecting 15 high-risk HPV subtypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 and 68, together with 3 low-risk HPV 6, 11 and 42 were selected respectively from Genbank and fixed on membrane to make DNA chip. PCR amplification and DNA chip technology were optimized. 100 clinical samples were used to investigate the effect of HPV genotyping DNA chip. Veracity of the genotyping results was verified by sequencing.

RESULTSFrom the 100 clinical samples, 30 were found to be HPV positive, including high-risk HPV subtypes 16, 18, 33, 45, 51, 58, and 66, and low-risk HPV 6, 11 and 42. The sensitivity tested by standard samples was up to 10 copies of HPV DNA.

CONCLUSIONThe HPV genotyping system developed here with DNA chip showed high sensitivity and specificity, suitable to be applied in clinical practice for HPV diagnosis and investigation on the prevalence of HPV sub-types.

Objective: To observe the improving effect of muscle regions of meridians needling method on the upper limb function in children with cerebral palsy of spastic hemiplegic type. Methods: A total of 100 children with cerebral palsy of spastic hemiplegia type were divided into a treatment group and a control group according to the visiting sequence, with 50 cases in each group. The control group was treated with conventional rehabilitation plus conventional acupuncture treatment. The treatment group was treated with conventional rehabilitation plus muscle regions of meridians needling method. The electromyography (EMG) signal values of triceps brachii and pronator teres were detected before treatment, and 3 months and 6 months after treatment. The clinical efficacy was evaluated by Peabody developmental motor scale-fine motor (PDMS-FM) and fine motor function measure (FMFM). Results: Three and six months after treatment, the EMG signal values of triceps brachii and pronator teres, grasping scores and visual-motor integrated scores of PDMS-FM and the FMFM scores in both groups increased to varying degrees compared with the same group before treatment, and the intra-group differences were all statistically significant (all P<0.05). Six months after treatment, the results of the above three items in the treatment group were all better than those in the control group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Muscle regions of meridians needling method added on the basis of conventional rehabilitation can effectively reduce the muscle tone of upper limb and enhance the muscle strength, and improve the upper limb function in children with cerebral palsy of spastic hemiplegia type. The efficacy is superior to that of the conventional rehabilitation plus conventional acupuncture treatment.

BACKGROUNDLiver transplantation has become the treatment of choice for patients with end-stage acute or chronic hepatic disease. Bile duct complications are common events after liver transplantation. The aim of this study was to evaluate the blood supply of the human bile duct and identify the underlying mechanisms of bile duct complications after liver transplantation.

METHODSThe duct supply branches from gastroduodenal artery and blood supply of extrahepatic bile duct system were re-evaluated through selective hepatic angiography from 600 patients. In addition, 33 cadavers were injected with latex casting material into the common hepatic artery, then the extrahepatic bile duct and the branches from the common hepatic artery were carefully dissected to visualize the gastroduodenal artery and its branching to the extrahepatic bile duct.

RESULTSThe bile duct artery arose from the branch of the gastroduodenal artery in 8.1% (49/600). Of these 49 individuals, the bile duct artery was supplied by the gastroduodenal artery (61.22%, 30/49), the proper hepatic artery (14.29%, 7/49), or both the gastroduodenal artery and the proper hepatic artery (24.49%, 12/49). In our study of 33 cadavers, the percentage that the bile duct artery arose from the gastroduodenal artery was 27.27%. The blood supply to the bile extrahepatic bile ducts was divided into different segments and formed longitudinal and arterial network anastomosed on the walls of the duct.

CONCLUSIONSThere is a close relationship between the duct supply branches from gastroduodenal artery and the blood supplying patterns of the extrahepatic bile duct system. In liver transplant surgery, the initial part of the gastroduodenal artery is preferred to be preserved in the donor liver. It is of great significance to improve the success rate of operation and reduce complications.

OBJECTIVETo investigate the clinical features of thyroid disease occurring in response to antiviral therapy in patients with chronic hepatitis C (CHC).

METHODSEighty-two patients diagnosed with CHC were recruited for study from our hospital between 2009 and 2010. All patients were given a 48-week course of antiviral combination therapy with pegylated-interferon (Peg-IFN; 180 mug qw ih) and ribavirin (RBV; 15 mg/kg bw). Patient sera was collected prior to treatment (baseline), at treatment weeks 24 and 48, and post-treatment week 24, and used to detect changes in levels of thyroid function markers, thyroid-specific and other autoantibodies, complement factors, and immunoglobulins (Igs). Differential expression of biomarkers was assessed between patients who developed thyroid disorder and those who did not.

RESULTSAt treatment week 48, 13.4% (11/82) of cases developed hypothyroidism, 3.7% (3/82) developed hyperthyroidism, 20.7% (17/82) tested positive for thyroglobulin antibody, and 22.0% (18/82) tested positive for thyroid peroxidase antibody. The patients who did not develop thyroid disease had significantly higher post-treatment levels (vs. baseline) of IgG (14.84 +/- 2.61 vs. 12.95 +/- 3.32 g/L, F = 10.458, P = 0.002) and C4 (0.26 +/- 0.09 vs. 0.22 +/- 0.08 g/L, F = 6.835, P = 0.011) and significantly lower IgM (0.86 +/- 0.48 vs. 1.00 +/- 0.42 g/L, F = 9.106, P = 0.003). The patients who developed thyroid disease showed no significant differences in the baseline and post-treatment levels of IgG, C4, or IgM. When the two groups of patients who did or did not develop thyroid disease were compared, there was no difference in the amount of patients who achieved sustained virological response.

CONCLUSIONAntiviral-induced thyroid disease in patients with refractory hepatitis C manifests as clinically-detectable abnormalities in serum levels of thyroid autoantibody and markers of hypothyroidism. Levels of other autoantibodies and Igs do not correlate with the development of thyroid disease in these patients, and thyroid disease does not appear to affect the efficacy of Peg-IFN + RBV antiviral therapy.

Objective To investigate the feasibility of combined CT angiography(CTA)of head,neck and aorta in acute type A aortic dissection (ATAAD) and whether the incremental craniocervical information benefits the surgeon and leads to improved clinical outcomes.Methods One hundred and twenty ATAAD patients in a CAC group underwent combined aortic CTA and 123 ATAAD patients in a control group underwent conventional aortic CTA.In the CAC group,the image quality was analyzed and critical CTA findings in craniocervical arteries were determined for further surgery procedure.The radiation dose,intraoperative cerebral protection method,and postoperative intensive care units(ICU)time,in-hospital time,neurologic dysfunction(ND)and all-cause mortality were compared between the two groups.Results The CAC group had all the carotid and cerebral arteries diagnosed successfully. There were 13 patients replaced conventional unilateral antegrade selective cerebral perfusion with bilateral one according to the head and neck CTA images in the CAC group. The CAC group had effective radiation dose,postoperative ND,ICU time and in-hospital time significantly lower than those of the control group (P<0.05).There were no statistical differences between the all-cause morbidities of the two groups (P>0.05).Conclusion A combined CTA of head, neck and aorta in ATAAD is feasible. The incremental craniocervical information may lead to improved clinical outcomes.

Objective:To observe the clinical efficacy of needling thirteen ghost acupoints for children with autism spectrum disorder. Methods:A total of 90 cases with autism spectrum disorder (ASD) aged between 2 and 6 years were randomly allocated into 2 groups by random number table. The control group (n=45) received routine rehabilitative training, and the treatment group (n=45) received acupuncture at thirteen ghost acupoints plus routine rehabilitative training. The Beijing Gesell developmental (Gesell) scale and autism behavior checklist (ABC) were used to assess the intellectual, language and behavior development before and 3 months after the treatment. Results:After the treatment, the total effective rate in the treatment group was 82.2%, versus 55.6% in the control group, showing a statistical significance (P<0.05). As for the scores of social, emotional and language in Gesell scale, there were significant intra-group differences in the treatment group (allP<0.05), and all the five subscales in the Gesell scale in the treatment group were significantly better than those in the control group (allP<0.05). As for the scores of ABC, there were significant intra-group differences in the treatment group (P<0.05), and the scores in the treatment group were significantly better than those in the control group (allP<0.05). Conclusion: Rehabilitation training plus acupuncture at thirteen ghost acupoints can significantly improve the intellectual, language and abnormal behavior in autism spectrum disorder children.
