Objective To study the epidemiological characteristics of diarrhea-predominant irritable bowel syndrome (IBS-D) as well as the relationship between the main syndromes and different factors. Method The relevant information of patients were collected by clinical epidemiological method and the relationship between the main characteristics of the IBS-D syndromes and different factors was explored with the major syndromes as the key link. Result Most of the cases aged 30～49 years old. Special hobbies of patients followed by drinking, smoking, addicting spicy, addicting coffee and so on. Poor emotion, mental stress and diet were the main inducements. Liver stagnation and spleen deficiency has the highest percentage (44.7%). The distribution of syndromes in different ages, different genders, different occupations and different education had no significant difference. Conclusion The number of IBS-D hospital visiting-patients is lower than the actual number of illness people. Mental factors are important internal factors, and dietary factors may be an important external factor. Different factors have no effect on the distribution of syndromes.

Objective To compare the efficacy of transumbilical-ultrafine gastroscope sympathectomy for severe palmar hyperhidrosis using two distinct levels of T3 and T4.Methods A total of 84 cases with severe primary hyperhidrosis were randomly allocated to undergo either T3 sympathectomy treatment (T3 group, n =42) or T4 sympathectomy treatment (T4 group, n =42) with no difference between the two groups.The operation time, postoperative hospital stay, patient's hands hyperhidrosis, axillary hyperhidrosis,complications were recorded at follow-up in 1,3,6,12 months.Results Operation on 84 patients were successful with mean operative time of T3 group being 55.02 ± 10.61 min and T4 group being 55.36 ± 10.51 min(P ＞ 0.05).The mean postoperative hospital stay were both 1.5 days.Patients were followed up for diaphragmatic hernia, umbilical hernia, Horner's syndrome and other serious complications for 12 months.No postoperative recurrence of palmar hyperhidrosis, severe compensatory sweating occurred in either group.The number of improved patients in T3 group's palmar hyperhidrosis,axillary hyperhidrosis, and foot hyperhidrosis were :42/42 cases, 10/16 cases, 21/29 cases, while those in T4 group were: 42/42 cases,16/17 cases 18/28 cases.Axillary hyperhidrosis improved to a larger extent in T4 group than in T3 group (P ＜0.05).There were 16(15 mild and 1 moderate)compensatory sweating in T3 group and 7(6 mild and 1 moderate) compensatory sweating in T4 group (P ＜ 0.05).Conclusion T3 and T4 thoracic sympathectomy using transumbilical-ultrafine gastroscope for primary palmar hyperhidrosis are safe, effective, and feasible.T4 sympathectomy is more effective in improving axillary hyperhidrosis than T3 and shows lower occurrence of postoperative compensatory hyperhidrosis.

Objective To evaluate the safety and feasibility of endoscopic transumbilical thoracic sympathectomy.Methods The technique was performed in 4 swine models.Under general anesthesia,a newly developed long abdominal trocar (60 cm in lengths) was placed through the umbilicus,which was also used to establish pneumoperitoneum.After insertion of gastroscope through this trocar,two small incisions of diagrams were created by needle-knife,through which the gastroscope was sent into the thoracic cavity to ablate the T3 ganglia by Hot biopsy forceps under One-lung ventilation.The animals were killed at the completion of the procedure.Results This procedure was completed in four pigs.The sympathetic chain was successfully ablated in all swine,as confirmed by gross surgical pathology and histology,the mean operative time was (81.7 ±15.4) minutes.There was no major bleeding.All bilateral T3 sympathetic chains were successfully ablated in the 4 swines as confirmed by gross surgical pathology and histology.There was no severe bleeding and damage to peripheral organs during the operation in any of the cases,and no prominent pneumothorax was revealed by postoperative chest X-ray radiography.Conclusion Endoscopic transumbilical thoracic sympathectomy is safe,feasible and effective with good cosmetic result.

Objective To observe the clinical curative effect and complications of different surgical incision in the treatment of bromhidrosis and to explore the best surgical method.Methods We retrospectively analyzed the clinical data of 352 patients with bromhidrosis from January 2011 to May 2017 and observed the long-term effects of different surgical methods.One surgical methods was apocrine pruning through the micro linear incision,another was apocrine pruning through the micro spindle incision.Then observation data was statistically analyzed.Results 190 cases were treated with micro linear incision method.The median incision healing time was 11.6d,healing time was 11.2-±0.6d,the incision of 170 cases were primary healed,primary healing rate was 89.5％.188 cases were cured for the long-term curative effect(98.9％),2 cases were markedly improved (1.1％).162 cases were treated with micro spindle incision method.The median incision healing time was 18.5d,healing time was 18.3 ± 0.4d,the incision of 125 cases were primary healed,primary healing rate was 77.2％,158 cases were cured for the long-term curative effect(97.5％),4 cases were markedly improved (2.5％).Apocrine sweat glands pruning through the micro linear incision and the micro spindle incision both can achieve good effect.The curative effect has no statistical difference.Whereas after the operation that apocrine sweat glands pruning through the micro linear incision,the wound healed faster,the rate of primary healing is higher,the difference was statistically significant.Conclusion It is the preferred surgical method of apocrine sweat glands pruning through the micro linear incision for the treatment of bromhidrosis.

Objective: To analyze the epidemiological characteristics of school foodborne disease outbreaks in Henan Province from 2011 to 2020 and to provide the basis for effective prevention and control of school foodborne disease outbreaks. Methods: The outbreaks of foodborne diseases in schools in Henan Province reported by the foodborne disease outbreak surveillance system from 2011 to 2020 were statistically analyzed. Results: A total of 47 outbreaks of school foodborne diseases were reported in Henan province in the past 10 years, with a total of 1 258 cases, 701 hospitalizations and 1 death. Zhengzhou, Zhumadian, Xinyang and Xinxiang were the top 4 cities in Henan Province in terms of the number of school foodborne disease outbreaks reported. The peak of foodborne illness incidents in schools was in June and September. The largest number of incidents occurred in middle school canteens and primary school canteens(all 12). The number of reported incidents (12) and the number of cases of foodborne diseases (371) in schools caused by cereals and their products were the largest. Pathogenic bacteria and their toxins were the main pathogenic factors that caused the outbreaks of foodborne diseases in schools, accounting for 78.26% of the identified causes. Bacillus cereus was the top pathogens causing foodborne diseases outbreaks in schools. The pathogenic factor that caused the largest number of cases was Diarrheogenic Escherichia Coli, and the pathogenic factor that caused the death cases was poisonous mushrooms. Apart from unexplained incidents, improper processing was the main link leading to foodborne diseases outbreaks in schools. Conclusion The primary and middle school students are the group with high incidence of foodborne diseases in schools. The supervision and management of school canteen should be strengthened in summer to prevent the outbreak of bacterial foodborne diseases caused by improper processing and storage of grain food.

Objective: Combining the aluminium content data of food in Henan Province with the data of children s food consumption, to evaluate probability of dietary aluminum exposure among primary school students. Methods: Database of nine types of aluminum containing food and their consumption among primary school students in Henan Province were established. The probability distribution of dietary aluminum exposure was calculated by Monte Carlo simulation using Crystal Ball 11.1.2.4 software, and the sensitivity analysis of exposure was conducted. Results: The average content of aluminum in fried bread stick was the highest, with the value of 150.89 mg/kg. The consumption of dietary aluminum was highest in steamed bun, with the value of 0.15 g. The average dietary aluminum exposure per kilogram of body weight was 1.99 mg per week of primary school students in Henan Province, accounting for 99.7% of the provisional tolerable weekly intake (PTWI). The 95th percentile of aluminum exposure per kilogram of body weight per week was 6.16 mg, which was three times of that of PTWI. Nearly 13.22% of primary school students had dietary aluminum exposure higher than PTWI. Among all kinds of food, the average aluminum exposure of fried bread stick per kilogram of body weight per week was the highest 1.19 mg. Aluminum content in fried bread stick accounted the highest proportion of average dietary aluminum exposure among primary school students. Conclusion The average dietary aluminum exposure level of primary school students in Henan Province is close to the PTWI established by JECFA, with the high consumption population exceeds the PTWI. Measures should be taken to reduce the dietary aluminum exposure risk of primary school students.

OBJECTIVETo investigate the distribution of HBV genotypes in Changzhou area and to clarify the genotype-related difference in the liver function, the level of HBV DNA and the long-term effect of lamivudine in the pathogenicity of HBV.

METHODSNested PCR and sequence analysis were conducted in 14 acute hepatitis (AH), 104 chronic hepatitis (CH), and 28 liver cirrhosis or hepatocellular carcinoma (LC/HCC) patients.

RESULTSOne hundred and forty six samples were positive for HBV DNA, and 51 samples were classified as genotype B (34.9%), 95 samples were classified as genotype C, serum ALT value was 383.8 +/- 335.7 IU in patients with HBV genotypes B, and 364.3 +/- 333.7 IU in genotypes C, HBV DNA value was 10(7.795 +/- 1.22) copies/ml in genotypes B and 10(7.69 +/0- 1.19) copies/ml in genotypes C, and there were 36 and 64 HBeAg positive cases in patients with genotypes B and C; there were no significant difference on the level of ALT, HBV DNA and the expression of HBeAg (P>0.05), but genotype C in LC/HCC was higher than CH (P<0.01). Twenty three genotype B and forty five genotype C patients received lamivudine treatment, after 48 weeks, 18 genotype B and 14 genotype C patients had higher ALT or HBV DNA positive.

CONCLUSIONSThese results indicate that genotype B and C existing Changzhou area; genotype C is associated with the development of severe liver disease and better therapeutic effect could be obtained in the patients with genotype C.
