Objective To seek a rational method of estimating the demands for medical services so as to work out regional health planning in a scientific way. Methods A metropolis including 19 counties and districts was selected as a region and demands for medical services were forecasted via retrospective analysis and the econometric model. Results A model of the demands for outpatient and inpatient services was obtained based on the impact of many social and economic factors on medical health services, and illustrations were given to indicate the demands for medical health services in the 19 counties and districts in future when prices should rise by 15% and 20%. Conclusion The econometric model can be used as a tool for estimating the demands for medical health services, and yet improvements need to be made.

Objective:To explore the effect of colonoscopy combined with X-ray stent implantation in the treatment of colorectal cancer intestinal obstruction, and analyze the risk factors of postoperative delayed bleeding.Methods:From November 2016 to December 2020, 382 patients with colorectal cancer intestinal obstruction in Hainan Provincial People′s Hospital were selected. Among them, 254 patients were treated by colonoscopy combined with X-ray stent implantation (stent implantation group), and 128 patients were treated by emergency radical resection (control group). The operation time, intraoperative bleeding, number of lymph node dissections, tumor diameter, incision length, exhaust time, hospital stay, fluid feeding time, fistulation, perioperative death and delayed bleeding were compared between 2 groups. Based on the random number generated by the computer, 254 patients who underwent colonoscopy combined with X-ray stent implantation were divided into training set (190 cases) and test set (64 cases) according to the ratio of 3∶1. In the training set, the patients were divided into postoperative delayed bleeding and non postoperative delayed bleeding, and the clinical indicators were compared; the multivariate Logistic regression model was performed to analyze the independent risk factors of postoperative delayed bleeding, and the prediction model of postoperative delayed bleeding was established and verified according to the independent risk factors.Results:All patients in the stent implantation group were successfully implanted with stents, and the obstructive symptoms were relieved 24 to 48 h after operation. The operation time, intraoperative bleeding, incision length, fistulation rate, exhaust time, hospital stay and fluid feeding time in stent implantation group were significantly lower than those in control group: (88.89 ± 5.97) min vs. (116.58 ± 20.17) min, (33.18 ± 16.52) ml vs. (92.35 ± 25.64) ml, (4.50 ± 0.96) cm vs. (14.26 ± 2.88) cm, 10.24% (26/254) vs. 98.44% (126/128), (1.18 ± 0.58) d vs. (1.53 ± 0.77) d, (7.69 ± 5.12) d vs. (12.88 ± 6.54) d and (1.46 ± 0.68) d vs. (2.12 ± 1.18) d, the number of lymph node dissections was significantly higher than that in control group: (19.88 ± 4.47) lymph nodes vs. (17.47 ± 3.11) lymph nodes, and there were statistical differences ( P<0.01); there were no statistical differences in tumor diameter and perioperative fatality rate between 2 groups ( P>0.05). Among 190 patients in the training set, 18 patients had postoperative delayed bleeding, with an incidence of 9.47%; 172 cases did not have postoperative delayed bleeding. The age, course of obstruction, complete obstruction rate, intestinal almost occlusion rate under enteroscopy, intraoperative bleeding rate and preoperative intestinal surgery history rate in patients with postoperative delayed bleeding were significantly higher than patients without postoperative delayed bleeding: (69.52 ± 10.54) years old vs. (58.65 ± 15.87) years old, (14.56 ± 10.12) d vs. (8.13 ± 7.68) d, 11/18 vs. 20.35% (35/172), 11/18 vs. 16.28% (28/172), 7/18 vs. 11.63% (20/172) and 12/18 vs. 37.79% (65/172), and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistics regression analysis result showed that old age, long duration of obstruction, complete obstruction, almost intestinal obstruction under enteroscopy and intraoperative bleeding were independent risk factors for postoperative delayed bleeding in patients with colorectal cancer intestinal obstruction undergoing colonoscopy combined with X-ray stent implantation ( OR = 3.925, 4.802, 1.727, 2.710 and 2.581; 95% CI 1.352 to 8.330, 1.064 to 8.869, 1.063 to 2.804, 1.118 to 4.400 and 1.689 to 3.479; P<0.05 or<0.01), while the history of preoperative intestinal surgery was not related to postoperative delayed bleeding ( P>0.05). The consistency indexes of nomogram training set and test set were 0.742 and 0.726 (95% CI 0.684 to 0.845 and 0.640 to 0.812). The receiver operating characteristic (ROC) curve analysis results of 2 models showed that the area under the curve (AUC) of the training set nomogram model and Tree Augmented Na?ve Bayes (TAN) model was 0.758 and 0.752 respectively, and the AUC of the test set nomogram model and TAN model was 0.702 and 0.706 respectively. The prediction accuracy of training set nomogram model and TAN model was 84.74%(161/190) and 85.26%(162/190) respectively, the prediction accuracy of test set nomogram model and TAN model was 82.81%(53/64) and 84.38%(54/64) respectively. Conclusions:Colonoscopy combined with X-ray stent implantation is safe and feasible in patients with colorectal cancer intestinal obstruction. But for the old age, long duration of obstruction, complete obstruction, almost intestinal obstruction under colonoscopy and intraoperative bleeding, careful operation should be carried out to reduce the occurrence of postoperative delayed bleeding.

Objective:To understand the clinical characteristics of pregnant women infected with dengue virus (DENV) in Ruili City, Yunnan Province, so as to provide basis for formulating effective diagnosis and treatment protocol of dengue fever in pregnant women.Methods:A total of 18 pregnant women infected with DENV hospitalized in Ruili People's Hospital in 2017 and 2018 were selected as observation group, and 18 non-pregnant women infected with DENV were selected as control group according to the age range of the observation group, and epidemiological and clinical data of patients in the two groups were retrospectively collected. Epidemiological characteristics, clinical symptoms and laboratory biochemical indexes of the two groups were compared and analyzed.Results:There were no significant differences ( t = - 0.032, 0.495, P > 0.05) in age [(27.9 ± 5.3) vs (27.9 ± 5.1) years old] and hospitalization stay [(6.8 ± 1.6) vs (6.6 ± 2.0) d] between the observation group and control group. One pregnant woman in observation group had early pregnancy abortion. Patients of both groups had fever in 18 cases (100.0%), headache, muscle aches, and chills in 14 cases (77.8%), anorexia in 15 cases (83.3%), and nausea and vomiting in 5 cases (27.8%); fatigue in 14 cases (77.8%) and 16 cases (88.9%), respectively; there was 1 case of rash in observation group (5.6%), and no rash in control group. There were no significant differences in the above mentioned clinical symptoms distribution between the two groups ( P > 0.05). On the first day of admission, the reduction proportions in red blood cells [61.1% (11/18) vs 5.6% (1/18)], hemoglobin [50.0% (9/18) vs 16.7% (3/18)], and hematocrit [61.1% (11/18) vs 16.7% (3/18)] in observation group were significantly higher than those in control group ( P < 0.05); on the fifth day of admission, the reduction proportions in hemoglobin [33.3% (6/18) vs 5.6% (1/18)] and hematocrit [33.3% (6/18) vs 5.6% (1/18)] in observation group were significantly higher than those in control group ( P < 0.05). Conclusions:The red blood cells, hemoglobin and hematocrit of pregnant women infected with DENV are significantly reduced, and there is a risk of miscarriage in early pregnancy. It is suggested that relevant departments should strengthen the training of medical staff to diagnose and treat pregnant women infected with DENV early.

Objective:By analyzing the clinical phenotypic characteristics and gene sequences of two patients with Treacher Collins syndrome(TCS), the biological causes of the disease were determined. Then discuss the therapeutic effect of hearing intervention after bone bridge implantation. Methods:All clinical data of the two family members were collected, and the patients signed the informed consent. The peripheral blood of the proband and family members was extracted, DNA was extracted for whole exome sequencing, and Sanger sequencing was performed on the family members for the mutation site.TCOF1genetic mutations analysis was performed on the paitents. Then, the hearing threshold and speech recognition rate of family 2 proband were evaluated and compared under the sound field between bare ear and wearing bone bridge. Results:In the two pedigrees, the probands of both families presented with auricle deformity, zygomatic and mandibular hypoplasia, micrognathia, hypotropia of the eye fissure, and hypoplasia of the medial eyelashes. The proband of Family 1 also presents with specific features including right-sided narrow anterior nasal aperture and dental hypoplasia, which were consistent with the clinical diagnosis of Treacher Collins syndrome. Genetic testing was conducted on both families, and two heterozygous mutations were identified in the TCOF1 gene: c. 1350_1351dupGG(p. A451Gfs*43) and c. 4362_4366del(p. K1457Efs*12), resulting in frameshift mutations in the amino acid sequence. Sanger sequencing validation of the TCOF1 gene in the parents of the proband in Family 1 did not detect any mutations. Proband 1 TCOF1 c. 1350_1351dupGG heterozygous variants have not been reported previously. The postoperative monosyllabic speech recognition rate of family 2 proband was 76%, the Categories of Auditory Performance(CAP) score was 6, and the Speech Intelligibility Rating(SIR) score was 4. Assessment using the Meaningful Auditory Integration Scale(MAIS) showed notable improvement in the patient's auditory perception, comprehension, and usage of hearing aids. Evaluation using the Glasgow Children's Benefit Inventory and quality of life assessment revealed significant improvements in the child's self care abilities, daily living and learning, social interactions, and psychological well being, as perceived by the parents. Conclusion:This study has elucidated the biological cause of Treacher Collins syndrome, enriched the spectrum of TCOF1 gene mutations in the Chinese population, and demonstrated that bone bridge implantation can improve the auditory and speech recognition rates in TCS patients.

Objective:
To explore the relationship between liver controlled attenuation parameters (CAP) and body fat mass and its distribution.
Methods:
From May to December 2018, 978 adult patients visited at the fatty liver center of the Third People's Hospital of Changzhou were treated. The patient's liver controlled attenuation parameters were measured by transient elastography and the body fat mass and its distribution were measured by bioelectrical impedance technology. Pearson’s correlation coefficient was adopted to describe the correlation between liver CAP value and body mass index (BMI), body fat mass index (BFMI), trunk fat mass index (TFMI), limbs fat mass index (LFMI) and visceral fat area (VFA). Receiver operating characteristic curve (ROC) and area under the curve (AUC) were used to evaluate BMI, BFMI, TFMI, LFMI and VFA to differentiate the cut-off points and efficacy of CAP for diagnosing grading of fatty liver changes in S0-1 and S2-3.
Results:
In 653 cases of male, S0 ~ S3 accounted for 4.90%, 3.37%, 22.36% and 69.37%, respectively, and in 325 cases of females, S0 ~ S3 accounted for 7.38%, 6.46%, 13.23% and 72.92%, respectively. Female patients had more visceral, trunk and limbs fat than male (

Increased intestinal barrier permeability, leaky gut, has been reported in patients with autism. However, its contribution to the development of autism has not been determined. We selected dextran sulfate sodium (DSS) to disrupt and metformin to repair the intestinal barrier in BTBR T+tf/J autistic mice to test this hypothesis. DSS treatment resulted in a decreased affinity for social proximity; however, autistic behaviors in mice were improved after the administration of metformin. We found an increased affinity for social proximity/social memory and decreased repetitive and anxiety-related behaviors. The concentration of lipopolysaccharides in blood decreased after the administration of metformin. The expression levels of the key molecules in the toll-like receptor 4 (TLR4)-myeloid differentiation factor 88 (MyD88)-nuclear factor kappa B (NF-κB) pathway and their downstream inflammatory cytokines in the cerebral cortex were both repressed. Thus, "leaky gut" could be a trigger for the development of autism via activation of the lipopolysaccharide-mediated TLR4-MyD88-NF-κB pathway.
