Chronic constipation is a common clinical disorder,which has different influences on patients’quality of life and work. With the increase in pressure and pace of modern life,the aging of population,the changes in dietary pattern and the challenge of social psychological problems,the overall prevalence of chronic constipation in general population is increasing in recent decades. However,the therapeutic efficacy of chronic constipation is still not satisfactory. This article reviewed the advances in study on treatment of chronic constipation.

Objective To analysis the changes of serum adiponectin level in patients with breast cancer and its clinical signifi‐cance .Methods 35 cases of serum adiponectin levels in breast cancer patients using enzyme‐linked immunosorbent assay ,and 35 healthy serum adiponectin level in peripheral blood of women ,analysis of significance of changes of serum adiponectin levels in breast cancer patients .Results Average serum adiponectin level in patients with breast cancer group(6 .13 ± 1 .55)μg/mL ,health group average serum adiponectin levels (8 .72 ± 1 .86)μg/mL ,the difference was statistically significant(P<0 .05) .Postmenopausal women in breast cancer group and health group compared with premenopausal women ,the serum adiponectin levels were signifi‐cantly increased ,there was a statistically significant difference(P<0 .05) .Lymph node metastasis of breast cancer serum adiponec‐tin levels were significantly lower in patients without lymph node metastasis in patients with breast cancer ,the difference was statis‐tically significant(P<0 .05) .Serum adiponectin level in breast cancer patients with stage Ⅱ and Ⅲ were significantly lower than breast cancer patients with stage Ⅰ ,there was a statistically significant difference(P<0 .05) .Conclusion Serum adiponectin levels as an important marker in the diagnosis of breast cancer ,serum adiponectin level and grade of the tumor ,lymph node metastases . Significantly reduced serum adiponectin level in patients with breast cancer ,and not under the influence of patients with menopause .

Objective To explore the correlation between Parkinson's disease(PD) and living habits.Methods 114 PD cases from ongoing PD prevalence survey in Beijing region and the neurological clinic center of Beijing Union Hospital and 205 controls matched on gender, race and residence were recruited in this study. Through in-person questionnaire interview, general data and living habits such as smoking, tea drinking and alcohol drinking were obtained and analyzed by population-based case control study.Results We observed reduced risk for PD in smokers(OR:0.538; 95%CI: 0.290, 0.998) and tea-drinkers(OR:0.199; 95%CI:0.114,0.346). There was no significant correlation between alcohol drinking and PD.Conclusion An inverse correlation exists in PD with smoking or tea drinking except for alcohol drinking.

OBJECTIVE: lo discuss the inmtluence of different thyroidectomy on perioperative blood calcium concentration. METHOD: Total number of patients was 240. These patients of thyroid tumors were recruited. Clinical and follow-up datum were retrospective analyzed. RESULT: Patients were divided into four groups by different operative methods. Group one was patients taken one-side thyroidectomy, group two taken one-side lymph node dissection plus, group three taken two-sides thyroidectomy,and group four taken one or two sides lymph node dissection plus. Group two was easier to become hypocalcemia and their calcium concentration decreased more remarkably, compared with group one. Patients taken two-sides thyroidectomy had the familiar outcome. CONCLUSION Patients taken lymph node dissection were easier to become hypocalcemia, compared with patients only taken thyroidectomy.

Objective To explore the relationship between tumor necrosis factor (TNF) gene polymorphisms in donors and recipients and the incidence and severity of acute graft-versus-host diseases (aGVHD) after unrelated allogeneic hematopoietic stem cell transplantation (alIo-HSCT). Methods Single nucleotide polymorphisms (SNPs) of TNFα-238 (G/A), TNFα-857 (C/T), TNFα-863 (C/A), TNFα-1031 (T/C), TNFβ + 252 (A/G) were analyzed by Multiplex SNaPshot analysis in 76 pairs of donors and recipients. Results Transplantation involving donors with TNFα-857 CC genotype resulted in a higher incidence of grade Ⅱ-Ⅳ aGVHD than donors with CT genotype (91.3% vs 8. 7% , P =0. 039). In the 23 patients with grade Ⅱ-Ⅳ aGVHD, no patients had TNFβ +252 AA genotype, 19 (82.6%) had GA genotype and 4 (17.4%) had GG genotype. There was a significant difference in the distribution pattern of the TNFβ +252 (AA, GA and GG) genotypes in these patients (P =0.03). There was no significant association of TNFα-238 (G/A), TNFα-863 (C/A) and TNFα-1031 (T/C) polymorphisms with the risk of aGVHD. Conclusion These results suggest donor TNFα-857 CC genotype is related to a higher incidence of grade Ⅱ -Ⅳ aGVHD, and patients with TNFβ +252 AA genotype have protection against the risk of grade Ⅱ -Ⅳ aGVHD.

Objective To investigate the three methods for sun protection factor determination in vivo in Chinese under the same condition, and to evaluate the feasibility and reliability of the three methods. Methods There were 45 healthy volunteers in Guangzhou area were involved in the study. All of them were randomly divided into three groups. Among them 15 volunteers were in the current method group, 5 volunteers in the simplified method group, and 25 volunteers were in the single-exposure method group. Two standard sunscreens of SPF 4 and SPF 15 and one sunscreen labeled as SPF 20 were tested by all the three methods in the study. Two experienced observers read results, respectively, under the same conditions. Results The volunteers in the current method group received the largest dose of UV light.The simple method was next to it and the single-exposure reduced 4-5 folds of UV dose received. The results of the two observers in the current method group and the single-exposure group were very close. But the test results of P3 were not completely coincident between the two observers in the simplified method group. SPFs value of the three sunscreens were 4. 12, 16.09, and 22.60 obtained by the observer 1 and 4. 18, 15.92, and 21.97 obtained by the observer 2, respectively. In the simplified method group, SPFs values of ＜4, ＞15, ＞20 and ＜4, ＜15, ＞20 were obtained by the two observers. In the single-exposure method group, SPFs values of the three sunscreens were 4.04, 15.34, 21.33 by the observer 1 and 3. 96, 15.82, 21.33 by the observer 2, respectively. Conclusion The single-exposure method is convenient and easily to operate and may replace the current method some day. The simple method is not valuable in determination of SPF labeled on the packages of sunscreens, but may be useful in supervision of the market sunscreen products.
