A total of 55 children aged under 14 years with cholecystolithiasis were treated at our hospital between January 2005 to December 2011.Their clinical data were collected and analyzed.The etiologies included pseudolithiasis (n =36),chronic hemolytic disease (n =2),obesity (n =9) and unknown (n =8).Among 50 cases on conservative treatment,42 cases were cured.Four cases underwent laparoscopic cholecystectomy.During a follow-up period of 2-4 years,there was no occurrence of significant complications.The removal of gallbladder stone was performed via laparoscopy plus choledochoscope in 1 case.There was no recurrence during a follow-up period of 2 years.Ceftriaxone sodium and obesity were the major cause of pediatric cholecystolithiasis.A proper selection of treatment regimens should be based upon the considerations of etiologies and symptoms.

Objective To explore the relationship between tumor necrosis factor-?(TNF-?)level in the serum of maternal women with intrauterine infection of Toxoplasma gondii and absortion.Methods An examination was carried out on TNF-? in maternal sera and DNA of Toxoplasma gondii in the cervical secretions,and the aborted tissues of the abortion group,and the cervical secretions of the control group by ELISA and PCR,respectively.Results The TNF-? levels increased in the sera of women with intrauterine infection of Toxoplasma before abortion as compared with those of the control group and those of themselves after abortions.There were high TNF-? levels in the sera of prognostication abortion women with Toxoplasma infection before the anti-Toxoplasma treatment as compared with those of the control group and those of themselves after the treatment with azithromycin.Conclusion The results suggest that Toxoplasma gondii infection is an important factor to increase the TNF-? level in maternal serum.

Objective To observe the efficacy of a rotating magnetic field and granisetron hydrochloride in preventing nausea and vomiting caused by a eisplatin regimen, and any side effects. Methods Sixty-eight patients receiving cisplatin regimen chemotherapy were randomly assigned to two groups: a magnetic treatment group and a drug treatment group. The patients in the two groups were exposed to a rotating magnetic field or received granisetron hydrochloride, respectively. The effects of the treatments were observed. Results Both treatments could effectively prevent and treat the vomiting caused by chemotherapy. The rate of response to the rotating magnetic field was 88.2% and to the drug 91.2%. However, tardive vomiting was significantly better controlled in the rotating magnetic field group. The incidence of side effects in the magnetic field group was 20.6% , and in the drug treatment group it was 45.6%. Conclusion The efficacy of a rotating magnetic field and granisetron in treating acute vomiting were simi- lar. The rotating magnetic field was more effective in preventing tardive vomiting and had fewer side effects. Magnetic therapy should be more generally applied in clinical practice.

Objective To explore a new method for one-stage repair of the intestinal leakage based on the principle of magnetic compression anastomosis. Methods Twenty-four dogs were randomly divided into experimental group (n = 12) and control group (n = 12) according to random number table. The model of upper and multiple intestinal leakages was established by making transverse incisions of 1 cm in length on the jejunum wall about 50 cm and 100 cm away from the Treitz ligament. Forty-eight hours later, two NdFeB magnetic rings with the magnetic flux of 2500 G were put into the intestine from the leak sites. The leak sites were pressed between the two rings. The ventages in the control group were sutured. The condition of the dogs was observed after the repair of the leakage. The excreting time was recorded, and the leakage pressures of the anastomotic stoma were detected.The positions of the magnetic rings in the experimental group were detected by X ray. Tissues of the anastomotic stoma were processed by hematoxylin eosin and Masson staining. All data were analyzed using the two-sample t test. Results Severe abdominal infection occurred 48 hours after the establishment of the model. All the intestinal leakages in the experimental group were successfully repaired and the dogs survived for a long time. The magnetic rings were excreted six or seven days after the repair. Eight dogs of the control group survived. The leakage pressure of the anastomotic stoma seven days after the repair was (134 ±23)mm Hg (1 mm Hg =0. 133 kPa) in the experimental group and (91 ± 18)mm Hg in the control group, respectively, with a significant difference between the two groups (t = 3.225, P ＜ 0.05). The leakage pressure of the anastomotic stoma 14 days after the repair was (281 ±7)mm Hg in the experimental group and (271 ±21) mm Hg in the control group, respectively, with no significant difference between the two groups (t =0. 988, P ＞ 0.05). Histological observation showed that after the magnetic compression anastomosis, the intestinal muscle and mucosa recovered well, inflammatory reaction was slight and less collagen fiber and scar was formed. Conclusions Application of magnetic ring with the magnetic flux of 2500 G in one-stage repair of the intestinal leakage in the state of severe abdominal infection is safe and reliable.

Purpose: Although obesity is associated with numerous diseases, the risks of disease may depend on metabolically healthy status. Nevertheless, it is unclear to whether metabolically healthy status affects risk of gastrointestinal (GI) cancer in general Chinese population. Materials and Methods: A total of 114,995 participants who met the criteria were included from the Kailuan Study. The study participants were divided into four groups according to body mass index (BMI)/waist circumference (WC) and metabolic status. Incident of GI cancer (esophageal cancer, gastric cancer, liver cancer, biliary cancer, pancreatic cancer, and colorectal cancer) during 2006-2020 were confirmed by review of medical records. The Cox proportional hazard regression models were used to assess the association metabolically healthy status with the risk of GI cancer by calculating the hazard ratios (HR) and 95% confidence interval (CI). Results: During a mean 13.76 years of follow-up, we documented 2,311 GI cancers. Multivariate Cox regression analysis showed that compared with the metabolically healthy normal-weight group, metabolically healthy obese (MHO) participants demonstrated an increased risk of developing GI cancer (HR, 1.54; 95% CI, 1.11 to 2.13) by BMI categories. However, such associations were not found for WC category. These associations were moderated by age, sex, and anatomical site of the tumor. Individuals with metabolic unhealthy normal-weight or metabolic unhealthy obesity phenotype also have an increased risk of GI cancer. Conclusion MHO phenotype was associated with increased risk of GI cancer. Moreover, individuals who complicated by metabolic unhealthy status have an increased risk of developing GI cancer. Hence, clinicians should consider the risk of incident GI cancer in people with abnormal metabolically healthy status and counsel them about metabolic fitness and weight control.

Objective Detecting of spermatozoal total RNAs by laboratory on chip gel electrophoresis so that it could provide better total RNAs for the sequent experiments, and spur the development of spermatozoal molecular biology. Methods Sperms of healthy adults were collected and then total RNAs were extracted by RNeasy mini kit(QIAGEN), detection and quality control were performed by loboratory on chip gel electrophoresis system. Meantime, the control RNAs were extracted from lymphocytes. Results It was found that there were a plenty of genes expressed in healthy sperms. Electrophoretic graphs showed that the total RNAs of spermatozoal had 2 bands which went ahead a little comparing to the normal somatic cells. The former peak appeared keenness, and the latter was broad and showed like a reversed U. The ratio of them was largely more than 2, no extra peaks were found in electrophoretic graph. Conclusion A simple,intuitionistic method to detect and control the quality of the healthy adults' spermatozoal total RNAs had been successfully constructed by using laboratory on chip gel electrophorosis.

ObjectiveTo investigate the prevalence of cholelithiasis in the employees of Kailuan Corporation and to provide a reference for effective preventive measures. MethodsA total of 101 510 in-service or retired employees of Kailuan Corporation were recruited. All of them completed checkups organized by Kailuan Corporation from June 2006 to October 2007. The cholelithiasis examination data of 1133 employees were lost and the data of 100 377 employees were finally included in the statistical analysis. Questionnaire survey, blood biochemical examination, and ultrasound examination of the gallbladder were carried out. According to the ultrasound examination results, the subjects were divided into cholelithiasis group and non-cholelithiasis group. Comparison of the means between the two groups was made by t-test and comparison of the incidence rates between the two groups was made by chi-square test. The risk factors for cholelithiasis were assessed using multiple logistic regression analysis. ResultsThere were 80 129 males and 20 248 females in the 100 377 subjects. Their ages ranged from 18 to 98 years (mean, 51.89±12.66 years). There were 98 109 subjects without cholelithiasis and 2268 subjects (2.3%) with cholelithiasis. The females had a significantly higher incidence of cholelithiasis compared with the males (2.5% vs 2.2%, χ2=4.60, P=0033). The incidence rate of cholelithiasis increased with age in both men and women. According to the result of logistic regression analysis, sex, age, body mass index, occupation, fasting plasma glucose, high-sensitivity C-reactive protein (hs-CRP), and cholecystitis were all risk factors for cholelithiasis and the odds ratios (95% confidence interval) of them were 0.765(0.687-0.853), 1.439(1.388-1493), 1.403(1.282-1.535), 0.821(0.706-0.955), 1.234(1.075-1.416), 1.080(1.022-1.142), and 12.519(10678-14678), respectively. ConclusionPeople with advanced age, female sex, obesity, hyperglycemia, high hs-CRP, cholecystitis, or unhealthy lifestyle have high risk of cholelithiasis.
