Objective To investigate the clinical efficacy of prucalopride in the treatment of severe chronic constipation.Methods The clinical data of 60 patients with severe chronic constipation [slow transit constipation (STC), functional defecation disorder (FDD) and constipation-predominant irritable bowel syndrome (IBS-C)] who were admitted to the Third Affiliated Hospital of Nanjing University of Chinese Medicine from February to August 2014 were prospectively analyzed.A prospective, clinical observational study was performed.Treatment plans included that patients withdrew the initial treatments of laxative and exema and took orally 2 mg prucalopride once daily for 2 weeks, and continued to be treated by oral prucalopride if frequency of the spontaneous complete bowel movement (SCBM) per week was satisfactory (or improvement of symptoms was more than 50%) till 4 weeks, and then were followed up after stopping prucalopride.If improvement of symptoms was less than 50% after 2-week treatment, other treatment plans were performed according to symptoms of patients from week 3 to week 6 : (1) for patients with STC, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients were satisfied with frequency of SCBM per week and without improvement of abdominal distension;prucalopride + Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week with abdominal distension or poor stool output;oral prucalopride + acupuncture were administered if patients were unsatisfied with frequency of SCBM per week or less bowel movements and without improvement of abdominal distension or poor stool output.(2) For patients with FDD, oral prucalopride + acupuncture + biofeed-back therapy were administered.(3) For patients with IBS-C, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients had abdominal distension;prucalopride Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week and no improvement of abdominal distension or poor stool output.All patients used a diary for recording the frequency of SCBM per week, stool consistence, exertion in defecation and adverse reactions, which was submitted to doctors for inputting data at the return visit weekly.Results There was good overall medicine compliance in patients.Of 60 patients, 43 patients completed treatments (21 with STC, 11 with FDD and 11 with IBS-C).After 2-week treatment, there were 19 patients with satisfied therapeutic effects, 14 with improvement of constipation and 10 with poor therapeutic effects.After 4-week treatment, constipation in 17 patients was cured, constipation in 18 patients was improved,and constipation in 8 patients was not improved.Nineteen of 60 patients were complicated with adverse reactions within 1 week of the medication, including 6 patients dropping out of the trial due to medication withdrawal and others with improvement by symptomatic treatment or spontaneous remission.Conclusions Prucalopride is effective for the treatment of severe chronic constipation with a good toleration, and it can improve the overall satisfaction of patients combined with Chinese herb decoction and acupuncture.

ObjectiveTo assess the value of transvalvular pressure gradient (TPG) by use of realtime color Doppler echocardiography in percutaneous balloon pulmonary valvuloplasty (PBPV).Methods Patients with pulmonic stenosis (80 cases) were performed by PBPV,in which the pilmonic annular diameter and TPG were measured by using of 2-D and color Doppler echocardiography in the different periods of this operation.Results The pilmonic annular diameter was not significantly difference by intraoperative echocardiography and radiography measurement (t =2.013,P > 0.05).And pressure measurement by catheterization pre- and post-dilatation was not markedly significant ( t =1.258,P >0.05).However,TPG in patients with the different degree of pulmonic stenosis were decreased significantly ( P <0.01).PBPV treatments in the mild pulmonic stenosis for twice got an excellent effect according to operation criteria,but PBPV treatment in patients with the moderate and severe pulmonic stenosis need to be done for three times.ConclusionsReal-time color Doppler echocardiography is an effective way and plays a guiding role in PBPV.

Objective:To explore the clinical application of autologous freezing fat granule injection grafting in facial rejuvenation.Methods:A total of 64 cases of facial skin soft tissues ageing atrophy were treated by transplantation of autologous purification freezing lipochondria. Autologous fat was obtained from patient's abdomen or thighs, centrifugated at low velocity and low pressure to remove the oil and fluid, then stored the lipochondria in -20℃. Rewarming the fat under 37 ℃ for 1 hour, we observed the integrity of the adipocyte and detected the vitality of the fat. Then the purified autologous fat was injected into the recipient site of the face.Results:The fat cell membrane and cell nucleus were clear and integrity after stored in -20℃ for 24 weeks, and the vitality of the fat was (88.89±1.23)%. 21 cases gained satisfactory clinical results by injecting once and 35 cases with 2 times injections, 8 cases with 3 times injections, the effects were satisfactory and there was no complication by follow-up from 6 to 24 months. 82.81% patients and doctors were satisfactory with the curative effect, and 1.56% patients and doctors were unsatisfactory.Conclusions:The effects are satisfactory of autologous purified freezing microparticle fat injected transplant. It has low absorptivity, can duplicate injection, and accept easily by people. It is a good method for facial rejuvenation and worth to spread in the clinical practice.

ObjectiveTo investigate the regulatory effect of Shoutaiwan on oxidative stress and pyroptosis in lipopolysaccharide (LPS)-induced human extravillous trophoblast (HTR-8/SVneo) cells and provide a new direction for deciphering the mechanism of action of Shoutaiwan. MethodLPS (100 μg∙L-1) was used to induce the injury of HTR-8/SVneo cells (modeling). Five groups were designed in this study, including a blank group, a model group, a Shoutaiwan (10% Shoutaiwan-containing serum) group, an antioxidant (1 mmol·L-1 NAC) group, and NOD like receptor thermoprotein domain 3 (NLRP3) inhibitor (50 μmol·L-1 MCC950) group. Cell viability was detected by cell counting kit-8 (CCK-8) kit. Hochest 33342/PI double fluorescence staining and flow cytometry were employed to observe cell death. The levels of interleukin-18 (IL-18), interleukin-1β (IL-1β), malondialdehyde (MDA), and superoxide dismutase (SOD) in cell supernatant was determined by enzyme-linked immunosorbent assay (ELISA). DCFH-DA probe was used to measure the level of intracellular reactive oxygen species (ROS). Western blot was employed to determine the protein levels of NLRP3, Caspase-1, gastermin D (GSDMD), and IL-1β in cells, and Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) to measure the mRNA levels of NLRP3 and Caspase-1 in cells. ResultCompared with the blank group, the modeling decreased the cell viability (P<0.01), elevated the levels of IL-1β, IL-18, ROS, and MDA, and weakened the activity of SOD (P<0.01). Furthermore, it up-regulated the protein levels of NLRP3, Caspase-1, GSDMD, and IL-1β and the mRNA levels of NLRP3 and Caspase-1 (P<0.01). Compared with the model group, Shoutaiwan, NAC, and MCC950 increased the cell viability (P<0.01). Further, Shoutaiwan and NAC lowered the levels of MDA and ROS and increased the activity of SOD (P<0.01). Shoutaiwan and MCC950 reduced the IL-1β and IL-18 in cell supernatant (P<0.01), and down-regulated the protein levels of NLRP3, Caspase-1, GSDMD, and IL-1β and the mRNA levels of NLRP3, Caspase-1, and IL-1β (P<0.05,P<0.01). ConclusionShoutaiwan can regulate oxidative stress and pyroptosis to attenuate the LPS-induced damage of HTR-8/SVneo cells, which may be the mechanism of Shoutaiwan in preventing recurrent spontaneous abortion.
