Methods: Thirty-four patients with STC, underwent colectomy during recent 10 years in our department , were subjected and followed for a mean length of 34 months, and their colon transits, defecograms, colonoscopic examination, sex hormone detection, and immunohistochemical studies were retrospectively reviewed. Results: The co-Ionic transit time ranged from 96 to 240 h, with a mean time of 136 h. Eighty-five percent of patients (29/34) accompanied with outlet obstructed constipation, and 50% ( 17/34) showed abnormal sex hormone levels. Colectomy obtained satisfactory results in most patients, except one case of recurrence. Moreover, more neurons positive to nitric oxide synthase (NOS) and lesser to vasoactive intestinal polypeptide (VIP) were seen in the colonic myenteric plexus. Conclusion: Colectomy produces a satisfactory functional outcome in the majority of patients undergoing surgery for slow transit constipation, but accompanied pelvic dysfunction must be corrected simultaneously.展开更多

Multilocus sequence typing analysis was conducted on 57 isolates of B. coagulans from 22 provinces or autonomous regions in China. B. coagulans isolates were highly diverse and a total of 33(sequence typings) STs were found. These isolates had a weak clonal population structure and strong indications of intraspecies recombination. The evolution direction of B. coagulans was not correlated with geography or isolation source. Fifteen strains were selected for further analysis based on proximity relationships from the phylogenetic tree. Five isolates(B. coagulans-1, B. coagulans-10, B. coagulans-39, B. coagulans-70 and B. coagulans-71) with good spore-forming ability relative to the rest of the isolates were evaluated for constipation relief. B. coagulans-39 significantly relieved constipation symptoms in mice by regulating intestinal flora, increasing the production of short-chain fatty acids and restoring the level of gastrointestinal regulatory peptides. Comparative genomic analysis showed the beneficial effects of B. coagulans-39 might be associated with specific functional genes that are involved in the utilization of various carbohydrates as primary substrates and short-chain fatty acid production.展开更多

Methods： STC model was established by feeding rats with 8 mg/（kg＇d） diphenoxylate for 120 d. An experimental model of chronic STC rat was used for separation of proteomics from colonic mucosa using two-dimensional electrophoresis （2-DE）. Proteins altered in expressional level were identified by Image Master 2DElite, mass spectrometry, and bibliometrics were applied to identify the differential protein expression and their clinical s observed in the pathogenesis lgn of ificance and function were analyzed. Results： Obvious differential protein expression was STC, including mast cell protease （A1）, non-specific dipeptidase （A2） and chondrosome succinate dehydrogenase precursor （A3）. The expressions of A1, A2 and A3 were down-regulated in the gel graph of STC rats Conclusion： The down-regulation of chondrosome succinate dehydrogenase, mast cell protease as well as non-specific dipeptidase in rat colon suggests the functional impairment of the oxidoreduction of mitochondrion is very important in the genesis and development of STC. The immunological reaction of STC rats is weakened, and the function of digesting and absorbing protein may be damaged to some extent.展开更多

To evaluate the ameliorating effect of camellia oil on constipation,two slowtransit costive mice models were established by water deprivation or sucralfate gavage. Administration of camellia oil（ 4. 0 and 8. 0 mL/kg/day） significantly shortened the defecation time,increased defecation mass and fecal water content,with efficacies comparable to that of hemp seed oil. Intestinal propulsion test showed that camellia oil significantly enhanced the propelling rates of the charcoal powder in the intestine. Meanwhile,camellia oil also significantly decreased the serum levels of nitric oxide（ NO）,nitric oxide synthase（ NOS） and vasoactive intestinal peptide（ VIP） and increased serum substance P in costive animals. These results suggested that camellia oil can largely relieve slowtransit constipation and enhance the gastrointestinal motility through modulation of serum gastrointestinal motility key factors such as NO,NOS and VIP and substance P.展开更多

It is universally recognized that the occurrence of hepatolithiasis is closely related to cholangitis, cholestasis, abnormal bile metabolism, anatomical abnormality of bile ducts, malnutrition and low socio-economic status. Surgery is the primary treatment method for hepatolithiasis in clinic, but some patients may still suffer from recurrence or complications after surgery. Traditional Chinese medicine(TCM) has its own unique advantages in preventing and treating recurrence of calculi. This article mainly explored the key points of common syndromes, TCM nursing methods and health guidance of acute attack of hepatolithiasis in order to further develop the advantages of TCM, improve its efficacy and standardized its nursing behavior.展开更多
