By analyzing the current status of randomized controlled trials （RCTs） on functional dyspepsia （FD） and irritable bowel syndrome （IBS） comorbidity， we identified several critical issues which include insufficient repor-ting of FD and IBS subtypes， inadequate risk assessment of drug combination， lack of composite， objective， and long-term outcomes， and weak evidence support for clinical practice guidelines. It is suggested that future clinical research on FD-IBS comorbidity should further strengthen the application of real-world studies. The use of composite outcomes and long-term follow-up is recommended to improve the quality of evidence， while greater attention should be paid to patients' preferences and self-management to enhance the applicability of findings. Based on the existing issues in clinical studies of traditional Chinese medicine （TCM） for FD-IBS comorbidity， we propose to consolidate the foundation of TCM-specific efficacy evaluation to better reflect the advantages of syndrome differentiation and treatment， optimize real-world study designs to better support clinical decision- making， and introduce intelligent objective evaluation technologies to improve the objectivity and accuracy of TCM clinical efficacy assessment.

Objective:To report a case of pediatric infected maxillary mucocele and review relevant literature. Methods:A 3 years and 9 months old male patient was involved. He had nasal congestion and runny nose for 3 months. He usually has pus and occasional bloody nose. Physical examination: A red lump in the right nasal cavity with complete obstruction of the nasal passage. CT and MRI showed a right sinus mass. The patients WBC was 4.76×10⁸, and CRP<0.5 mg/L. Drainage and marsupialization were performed by endoscopy. Results:No purulent discharge was observed during follow-up, and the recovery was good. Conclusion:Enhanced CT or MRI shows typical circular enhancement shadows in infected maxillary mucocele. This indicates that endoscopic sinus surgery has a definite therapeutic effect. Drainage and marsupialization of maxillary mucocele are sufficient.

Objective To investigate the effect and safety of transcutaneous electrical stimulation at Zusanli acupoint for elimination of gastrointestinal poison in patients with oral organophosphorus pesticide poisoning. Methods A prospective study was conducted, including 62 patients with oral organophosphorus pesticide poisoning from September 2013 to February 2015 in the Department of Emergency of Xingtai People's Hospital of Hebei Province. The patients were divided into a observation group and a control group (each, 31 cases) in accord with the principle of simple random sampling. All the patients in two groups were given comprehensive treatment according to the diagnosis and treatment of the guide for organic phosphorus pesticide poisoning. In addition, the transcutaneous electrical stimulation at bilateral Zusanli acupoints was carried out in the observation group, once therapeutic time 30 minutes and every 8 hours once, and stopped until the discharge of melena. The incidence of vomiting after application of cathartics, the first stool time, the time of melena discharge, daily defecation frequency, the time of reaching atropinization, the total amount of atropine used, the time of cholinesterase (ChE) activity returning to its 1/2 normal activity, the length of stay in hospital, cure rate and mortality were observed in both groups. The changes in hemodynamics and pulse blood oxygen saturation (SpO2) were observed before and after transcutaneous electrical acupoint stimulation, and the occurrence of adverse reactions in the therapeutic course were observed in the observation group.Results After application of cathartics, the incidence of vomiting in control group was significantly higher than that in the observation group [32.2% (10/31) vs. 9.7% (3/31),P < 0.05]. In the observation group, the first stool time (hours: 9.3±3.6 vs. 11.6±5.2) and the time of melena discharge (hours: 11.3±5.3 vs. 14.5±6.8) were significantly shorter than those in the control group (both P < 0.05); while the frequency of bowel movements during catharsis was higher than that of the control group (times/d: 4.3±0.5 vs. 3.1±0.4,P < 0.01). In the observation group, the time reaching atropinization (hours: 66.3±22.8 vs. 84.6±24.2), the total amount of atropine used (mg: 66.3±22.8 vs. 84.6±24.2), and the time of ChE activity returning to its 1/2 normal range (days: 6.1±2.4 vs. 8.3±3.9) were significantly shorter than those in the control group (allP < 0.01). At the end of treatment, the average length of stay in hospital was shorter (days: 11.3±2.8 vs. 13.4±4.2,P < 0.05) and the cure rate was higher [96.8% (30/31) vs. 83.9% (26/31),P < 0.05] in the observation group than those in the control group; in observation group, the hemodynamics and SpO2 before and after acupoint electrical stimulation did not change significantly; in the course of treatment, no adverse reactions occurred.Conclusion The addition of transcutaneous electric stimulation at bilateral Zusanli acupoints in patients with oral organophosphorus pesticide poisoning has following advantages: lowering the incidence of vomiting during catharsis, enhancing the cathartic effect, promoting gastrointestinal poisoning discharge as soon as possible, reducing total atropine used during hospitalization, shortening the time reaching atropinization, shortening the duration of hospitalization, promoting the recovery of cholinesterase activity and elevating clinical therapeutic effects.

Objective To observe the effect of oral motor exercise on the feeding behaviour of autistic children. Methods 59 children with autism were assigned to control group (n=29) and exercise group (n=30). The control group received diet intervention, while the exercise group received oral motor exercises in addition. Both groups were assessed with questionnaire related to children's diet before and after treatment. Results Bad feeding behaviors such as little eating, overlength eating, picky eating, partial eating, refuse to eat significantly improved after treatment in the exercise group (P<0.05), and improved more than in the control group (P<0.05). Stereotyped feeding behavior improved after treatment in both groups (P<0.05) and there was no difference between 2 groups (P>0.05). Conclusion Oral motor exercises may improve the feeding behaviour of autistic children.

Objective To explore the effect of artificial and computer-assisted cognitive training on visuospatial impairment. Methods63 patients with visuospatial impairment were randomly assigned to artificial group (n=21), computer-assisted training group (n=21) and integrationgroup (n=21). The artificial group received conventional cognitive training while the computer-assisted training group used computerto assist cognitive training, and the integration group combined computer with conventional cognitive training. All groups were assessedwith Loewenstein Occupational Therapy Cognitive Assessment (LOTCA). Results All groups improved significantly after training(P<0.001). There were no significant difference between 3 groups in visual perception, spatial perception, and motor praxis after training.Compared to the computer-assisted training group, the integration group and the artificial group improved more significantly in visuomotororganization after training. Conclusion Artificial cognitive training and computer-assisted training can effectively improve the cognitivefunction of patients with visuospatial impairment.

Objective To understand with greater clearness the genetic polymorphism of (GCT)n repeat of MHC class I chain-related gene A (MICA)in some Chinese populations and provide preliminary genetic evidence for the independent origin of Chinese Baima Tibetan (BMT). Methods ACD-blood or saliva specimens of 411 unrelated individuals from four Chinese populations were collected. A primer pair spanning exon 5 of MICA gene was used to amplify the GCT region. Alleles were detected by PCR and denaturing PAGE. Comparison of the allelic distributions among the four populations was carried out. Results Five previously reported alleles have been observed in all the four populations, but the allelic distributions are different from one another. The most frequent allele is the A5 in all the four populations (0.325 in BMT, 0.345 in Tibetans, 0.390 in Chengdu Hans and 0.319 in Qiangs). A5.1 allele is the second most frequent allele in Chengdu Hans (0.230) and in Qiangs (0.293), while the second most frequent alleles for BMT and Tibetans are A4 (0.254) and A9 (0.272) respectively. The distribution of alleles in BMT is significantly different from that in the other three populations. Conclusion Alleles of MICA gene exon 5 are conservative in all populations studied so far. The results suggest that genetically BMT might be an independent ethnic population.

THe positive correlativity of fecal examination and soluble antigen from two kinds of adult clonorchis sinensis was nearly 90%. Results of field survey showed that there was no obvious difference between the positive rates of fecal examination and that of ELISA. The positive correlativity was 89. 3%, and the negative correlativity was 92. 8% with 2309 cases. There was close relationships between positive correlativity and the clonorchis sinensis egg density (amount of egg/per gram fece) of the infected people. The positive correlativity of seriously infected people was as high as 97. 9%. while the positive correlativity of those with lighter infection was only 61. 1%. The more serious the infection, the serum antibody titers. was much higher.

Objective Studies on the changes of gastrin and SS immunoreactive cells in pancreatic islets during experimental gastric ulcer. Methods The immunohistochemical ABC technique was used.
