Objective: To observe the clinical effect of heat-sensitive moxibustion plus lactulose oral liquid for postoperative constipation of mixed hemorrhoid.Methods: A total of 70 patients were randomized into a treatment group and a control group, with 35 cases in each group by a random number table. Patients in the control group received lactulose oral liquid alone, while those in the treatment group received additional heat-sensitive moxibustion at Shenque (CV 8). The treatment was given once a day for 15 consecutive days. The defecation interval time, defecation duration, the scores of stool form, visual analog scale (VAS) and patient assessment of constipation quality of life questionnaire (PAC-QOL), as well as the serum substance P (SP) and nitric oxide (NO) levels were measured before and after treatment. Results: After treatment, the stool form score, defecation interval time and defecation duration in the two groups dropped significantly (all P<0.05), and they were lower in the treatment group than in the control group (all P<0.05). After treatment, the VAS scores in the two groups dropped significantly (both P<0.05), and it was lower in the treatment group than in the control group (P<0.05). After treatment, the PAC-QOL scores in the two groups dropped significantly (both P<0.05), and it was lower in the treatment group than in the control group (P<0.05). After treatment, the serum SP and NO levels in the two groups improved significantly (all P<0.05), and showed statistically significant differences between the treatment group and the control group (both P<0.05). Conclusion: Heat-sensitive moxibustion plus lactulose oral liquid can improve stool form, shorten defecation interval time and defecation duration, alleviate defecation pain, and improve quality of life (QOL) for patients with postoperative constipation of mixed hemorrhoid, which may be related to the regulation of the SP and NO levels.

Incidence of thyroid cancer has continuously increased in the last three decades globally. A similar trend of thyroid cancer incidence appeared in China. New cases and deaths of thyroid cancer in China accounted for 15.6% and 13.8% of the global new cases and deaths in 2012. The incidence in East China was the highest while that in Middle China was the lowest. Thyroid cancer was more common in urban areas than in rural counterparts. The incidence was substantially higher in female patients than male. Thyroid cancer occurred most commonly in middle age. Radiation exposure, iodine suffciency or deifciency, sex hormone and genetic mutations were risk factors for thyroid cancer. To prevent it, potassium iodide should be taken to prevent radiation fallout in nuclear accidents, unnecessary exposure to radiation from medical imaging is reduced, iodine surveillance system is improved and appropriate standards for iodized salt are established.

OBJECTIVEPrader-Willi syndrome (PWS) is an example of a human genetic disorder that involves imprinting genes on the proximal long arm of chromosome 15 and SNRPN gene as a candidate gene for this syndrome. The purpose of this study was to show the molecular genetic defects and genomic imprinting basis in Chinese PWS patients and to evaluate the clinical applications of a differential diagnostic test for PWS.

METHODSFluorescence in situ hybridization (FISH) and methylation-specific PCR (MSPCR) techniques were applied for 4 clinically suspected PWS patients. Using three probes, including SNRPN probe for identification of the critical locus in PWS region, D15Z1 and PML control probes for identification of the 15p arm and 15q arm, the authors detected the deletions 15q in PWS. MSPCR was based on sodium bisulfite treatment of DNA and PCR primers specific for the maternal and paternal allele.

RESULTSWhen hybridized with mixed probes, it was found in 2 patients that the central specific signal was absent, but both the flanking control signals were retained, indicating SNRPN gene deletion of chromosome 15q11-13. Bisulfite-modified DNA from all PWS children amplified with methylated allele-specific primer pair showed only maternal 131bp PCR product, indicating the maternal uniparental disomy (UPD15).

CONCLUSIONGenomic imprinting plays an important role in the molecular pathogenesis of PWS that caused by paternal microdeletions of 15q11-q13 or maternal UPD of chromosome 15. The basic defect seemed to be an absence of function of PWS genes that are normally expressed only from the paternal chromosome 15. MSPCR is a rapid and simple PCR-based assay compared with other cyto-molecular tests and its results were consistent with the clinical diagnosis of PWS, so it seems to be a reliable diagnostic method for PWS patients who show abnormal methylation at SNRPN. The genetic differential tests for PWS are important in determining familial recurrence risk.
