OBJECTIVES: To explore the effect of acupuncture and moxibustion on intestinal flora in the rats with diarrhea-predominant irritable bowel syndrome (IBS-D) based on 16S rDNA technique. METHODS: Ten rats were randomized from 58 SPF-grade male SD rats to be the blank group. The remained 48 rats were prepared to be IBS-D models by the modified method of acetic acid enema combined with binding tail-clip stress. Forty successfully-modeled rats were randomly divided into a model group, an acupuncture group, a moxibustion group and a western medication group, with 10 rats in each one. In the acupuncture group, the needle was inserted at bilateral "Zusanli" (ST 36) and remained for 15 min in each rat. In the moxibustion group, the suspending moxibustion was delivered at bilateral "Zusanli" (ST 36) for 15 min. The rats in the western medication group were given pinaverium bromide suspension (10 mL/kg) by intragastric administration. The above interventions were performed once daily for consecutive 14 days. The body mass and the score of fecal trait were compared before and after modeling, as well as after intervention in each group. Fecal water content, diarrhea index and colon transit time (CTT) were measured after modeling and intervention in the rats of each group separately. After intervention, the colonic morphology of rats in each group was observed, and using 16S rDNA technique, the intestinal flora was detected. RESULTS: After modeling, compared with the blank group, the body mass and CTT were reduced (P<0.01); fecal trait scores, fecal water contents and diarrhea index increased (P<0.01) in the other 4 groups. After intervention, the body mass and CTT of the rats decreased (P<0.01), and fecal trait score, fecal water content and diarrhea index increased (P<0.01) in the model group compared with those in the blank group. In the acupuncture group, the moxibustion group and the western medication group, when compared with the model group, the body mass and CTT were elevated (P<0.01), while fecal trait scores, fecal water contents and diarrhea index declined (P<0.01). Compared with the western medication group, fecal water content decreased in the acupuncture group and the moxibustion group (P<0.05), while CTT increased in the acupuncture group (P<0.01), the body mass increased and fecal trait score was dropped in the moxibustion group (P<0.05). The colonic mucosa structure was clear and complete, and there was no obvious inflammatory cell infiltration in the blank group. The mild interstitial edema of intestinal mucosa was presented with the infiltration of few inflammatory cells in the model group. There was the infiltration of few inflammatory cells in the mucosa of the acupuncture group, the moxibustion group and the western medication group. Compared with the blank group, the indexes of Richness, Chao1, ACE and Shannon decreased in the model group (P<0.05). Indexes of Richness, Chao1 and ACE increased in the acupuncture group and the moxibustion group (P<0.05), and the Richness index in the western medication group increased (P<0.05) when compared with those in the model group. The relative abundance of Bacteroidetes, Proteobacteria and Prevotella increased (P<0.05), and that of Firmicutes and Muribaculaceae decreased (P<0.05) in the model group compared with those in the blank group. When compared with the model group, the relative abundance of Bacteroidetes, Proteobacteria and Prevotella was reduced (P<0.05), while that of Firmicutes and Muribaculaceae increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group; and that of Actinobacteria and Bifidobacterium increased in the acupuncture group and the moxibustion group (P<0.05). Compared with the blank group, the relative abundance of lipopolysaccharide (LPS) biosynthesis was elevated (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis decreased (P<0.05) in the model group. The relative abundance of LPS biosynthesis was dropped (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group compared with those of the model group. CONCLUSIONS Either acupuncture or moxibustion can relieve the symptoms of IBS-D and protect intestinal mucosa, which may be associated with regulating the structure of intestinal flora and promoting nutrient metabolism and biosynthesis.

Postzygotic mutations are acquired in normal tissues throughout an individual's lifetime and hold clues for identifying mutagenic factors.Here,we investigated postzygotic mutation spectra of healthy individuals using optimized ultra-deep exome sequencing of the time-series samples from the same volunteer as well as the samples from different individuals.In blood,sperm,and muscle cells,we resolved three common types of mutational signatures.Signatures A and B represent clock-like mutational processes,and the polymorphisms of epigenetic regulation genes influence the pro-portion of signature B in mutation profiles.Notably,signature C,characterized by C＞T transitions at GpCpN sites,tends to be a feature of diverse normal tissues.Mutations of this type are likely to occur early during embryonic development,supported by their relatively high allelic frequencies,presence in multiple tissues,and decrease in occurrence with age.Almost none of the public datasets for tumors feature this signature,except for 19.6％of samples of clear cell renal cell carcinoma with increased activation of the hypoxia-inducible factor 1(HIF-1)signaling pathway.Moreover,the accumulation of signature C in the mutation profile was accelerated in a human embryonic stem cell line with drug-induced activation of HIF-1α.Thus,embryonic hypoxia may explain this novel signature across multiple normal tissues.Our study suggests that hypoxic condition in an early stage of embryonic development is a crucial factor inducing C＞T transitions at GpCpN sites;and indi-viduals'genetic background may also influence their postzygotic mutation profiles.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

Objective To observe the therapeutic effect of Lai's acupuncture therapy combined with Chinese herbal decoction for the treatment of infertility with ovulatory dysfunction, and to summarize the experience of Professor Lai Xin-Sheng in treating infertility. Methods Ninety-six infertility patients with ovulatory dysfunction were randomized into treatment group and control group, 48 cases in each group. The treatment group was treated with Lai's Tongyuan acupuncture therapy for regulating Governor Vessel to tranquilize mind, inducing meridian Qi to original Qi, and was also given oral use of Chinese herbal decoction of Lai's Yiyun Recipe for promoting gestation. The control group was treated with Chinese herbal decoction alone. The treatment began exactly after the completion of menstruation period and lasted 15 days for one treatment course, covering 3 courses. And then the patients of the two groups were followed-up for 3 months. Therapeutic effect and pregnancy rate were evaluated after treatment, serum levels of estradiol and progesterone were examined, and abdominal ultrasonography was used for monitoring the maximum diameter of the dominant follicles and endometrial thickness before and after treatment. Results (1) Three cases from the treatment group and 5 cases from the control group were dropped out, and the final case number in the treatment group and control group was 45, 43 respectively. (2) The total efficiency of the treatment group was 88.9％, and that of the control group was 81.4％. The effect of the treatment group was better than that of the control group (P < 0.05). (3) The pregnancy rate of the treatment group was 73.3％, higher than that of the control group (51.2％), the difference being significant (P < 0.05). (4) After treatment, the maximum diameter of the dominant follicles and endometrial thickness in the two groups were obviously improved(P < 0.05 compared with those before treatment), and the improvement in the treatment group was superior to that in the control group (P < 0.05). (5) After treatment, the serum levels of estradiol and progesterone in the two groups were obviously improved(P < 0.05 compared with those before treatment) , and the improvement in the treatment group was superior to that in the control group(P < 0.05). Conclusion The therapeutic effect of Lai's acupuncture therapy combined with Chinese herbal decoction is superior to that of Chinese herbal decoction alone, showing an obvious synergistic effect by shortening the course of treatment and enhancing pregnancy rate.

Objective To observe the clinical efficacy of acupuncture plus medication in treating chronic pelvic inflammatory disease. Method By using the random number table, sixty-eight patients with chronic pelvic inflammatory disease were randomized into an acupuncture-medication group of 34 cases and a medication group of 34 cases. The clinical efficacies were compared after 2 courses of treatment, and the symptoms and body signs scores and syndrome score of traditional Chinese medicine (TCM) were also compared. Result There was a significant difference in comparing the therapeutic efficacy between the acupuncture-medication group and the medication group (P<0.05). After the treatment, the symptoms and body signs scores and TCM syndrome score dropped significantly in both groups (P<0.05), indicating that the two groups both had improvement in the symptoms, body signs and TCM syndrome; there were significant between-group differences in comparing the score differences in the symptoms and body signs scores and TCM syndrome score after the treatment (P<0.05), and the acupuncture-medication group was higher than the medication group. Conclusion Acupuncture plus medication can better ameliorate the symptoms and body signs and TCM syndrome in chronic pelvic inflammatory disease.

Objective: The purpose of this study was to explore the surgery-first approach in sequential combined orthodontic-orthognathic treatment to shorten total treatment duration and improve the clinical outcome. Methods: This study included 185 patients with Angle classⅢ malocclusion. The patients were divided into 3 different types according to cephalometry analyses and facial features. ①Type Ⅰ: mandibular prognathism or asymmetry mandibular prognathism; ②Type Ⅱ: mandibular prognathism and maxillary retrusion; ③ Type Ⅲ: mild Angle′s Class Ⅲ malocclusion, cross bite in anterior teeth, or normal overlap and overbite relation with midfacial hypoplasia. All of patients received surgery first approach therapy. The surgical procedures were chosen according to different malformation types. Type Ⅰ was treated with the sagittal split ramus osteotomy (SSRO). Type Ⅱ was treated by Le Fort Ⅰmaxillary osteotomy combined with SSRO. Type Ⅲ underwent anterior subapical osteotomy combined pyriform aperture augmentation with biomaterials as well as maxillary anterior orthodontics. All patients received postoperative rapid orthodontic treatment for 6-12 month after 2 weeks of operation. Using the straight arch wire techniques and the class Ⅲ intermaxillary traction, we removed the overcrowding upper and lower teeth, the compensatory axial tilt of teeth, and the deviation of the dental arch and maintained the neutral relationship of the molar. The mandible Hawley retaining devices were used during the maintaining stage. Results: The cases in study acquired satisfactory clinical outcome, which included the shortened overall treatment duration, the significantly improved facial features, the corrected occlusion relationship, and the restored function of mastication and temporomandibular joint. There were some complications as follows: intraoperative fracture (6 cases, 3.24%), the inferior alveolar nerve bundle injury (2 cases, 1.1%), and temporary open-bite that diminished by inter-maxillary elastic distraction one month after operation (19 cases, 10%). All cases in this study accepted postoperative orthodontic treatment. Follow-up time ranged from 6 months to 5 years. The cephalometric analysis results of 126 cases who had complete image data and over 6 months of follow-up showed that hard and soft tissue indexes were restored to normal range after combined orthognathic-orthodontic treatment. The stability of the maxillary and occlusive relationship of SFA(surgery-first approach) was similar to that of the COS(conventional orthodontics-first system) [relapse ratio=(T2-T1)/(T1-T0)×100%]. Over six months of follow-up , SNB and ANB showed that the average relapse ratio were 22% and 19.8%, whereas the relapse angle are less than 2°. Conclusions The Surgery-first approach could be used to treat most patients with Angle skeletal Class Ⅲ malocclusion, but the indications and the surgical procedures should be noticed and chosen.

Objective To evaluate the efficacy and safety of one-step dilation technique in minimally invasive percutaneous nephrolithotomy (MPCNL). Methods Clinical data of 2813 patients who underwent MPCNL by one-step dilation technique from February 2011 to March 2015 was retrospectively analyzed. Results 2813 patients were successfully underwent MPCNL by one-step dilation, including 2383 cases who were accessed by single tracts (84.71%) and 430 (15.29%) cases by multiple tracts. The mean operating time was (78.6 ± 41.1) min, the mean tract accessing time was (2.3 ± 0.8) min.The stone-free rate after one session operation was 78.59%. It improved to 91.50% one month after operation. During and after operation, 93 cases needed transfusion, 21 underwent selective renal artery embolization. Adjacent viscera damage: 9 cases with pleural lesions and 1 case with colon injury, 13 cases with urinary extravasation, perirenal hematoma in 15 cases, without liver and spleen injury. Septic shock in 2 cases, who was recovered after anti-infection treatment. Conclusion One-step dilation is safe and effective technique to establish tracts in MPCNL, which can reduce X-ray exposure and operation time, but does not increase the risk of bleeding.
