Objective:To investigate the clinical efficacy of different administration methods for labor analgesia.Methods:This randomized controlled study was conducted on 152 parturient women who underwent vaginal delivery at the Xinxiang Central Hospital from February to June 2023. These women were divided into a control group and an observation group, with 76 women per group. Women in the control group received 3 mL of 0.1% ropivacaine hydrochloride after routine epidural catheterization, followed by 3 mL of analgesic drugs after 3 minutes. For those without any special reactions, an analgesic pump containing 9 mL of medication was used after 3 minutes until the end of labor. In the observation group, 3 mL of 0.1% ropivacaine hydrochloride was administered as a trial dose before the epidural catheter was inserted into the epidural space. After 3 minutes, the postpartum woman lay flat and was given another 3 mL of analgesic pump medication. After 3 additional minutes, an additional 9 mL of the medication was administered. The analgesic pump was connected and turned on until the catheter was removed after delivery. The epidural catheter failure rate was assessed in each group. Before epidural puncture (T 1), within 30 minutes after the onset of anesthesia (T 2), and at the time of full dilation of the cervix (T 3), Visual Analogue Scale scores, the number of patient attempts to additionally use an analgesia pump, maternal satisfaction, the number of cases requiring cesarean section conversion, the incidence of adverse reactions (such as nausea, vomiting, and fever), and Apgar scores for newborns were recorded in each group. Results:The epidural catheter failure rate in the observation group was 1.3% (1/76), which was significantly lower than 10.5% (8/76) in the control group ( χ2 = 5.79, P < 0.05). At T 2 and T 3, the Visual Analogue Scale score in the observation group was (0.89 ± 0.08) points and (2.1 ± 0.07) points, respectively, which were significantly lower than (2.55 ± 0.07) points and (3.35 ± 0.07) points in the control group ( t = 238.54, 133.17, both P < 0.001). The number of patient attempts to additionally use an analgesia pump in the observation group was (1.00 ± 0.84) counts, which was significantly less than (4.00 ± 0.65) counts in the control group ( t = 29.47, P < 0.001). Maternal satisfaction in the observation group was 100% (76/76), which was significantly higher than 92.1% (70/76) in the control group ( χ2 = 6.25, P < 0.05). The number of cases requiring cesarean section conversion in the observation group was 0 (0/76), which was significantly lower than 52.6% (4/76) in the control group ( χ2 = 4.10, P < 0.05). Conclusion:Administering a trial dose (3 mL) of 0.1% ropivacaine hydrochloride before placing the epidural catheter during labor analgesia can greatly increase the placement success rate of the catheter and enhance pain relief effectiveness. This has a certain clinical application value.

ObjectiveTo explore the association between short-term exposure to atmospheric fine particulate matter （PM2.5） and ozone （O3） and systemic inflammatory indicators in patients with pneumonia， and to identify the susceptible populations. MethodsFrom September 2018 to April 2020， data of 1 480 patients admitted for pneumonia was collected from a tertiary hospital in Taiyuan City. Generalized additive models （GAMs） were used to explore the associations between PM2.5 and O3 exposure and inflammatory indicators of patients with pneumonia； and to explore the susceptibility factors and susceptible populations to PM2.5 and O3 exposures through stratified analyses. ResultsThe short-term exposure to PM2.5 was associated with changes in peripheral blood C-reation protein （CRP）， erythrocyte sedimentation （ESR）， easinophil （EOS）， neutrophil （NEU） and neutrophil-lymphocyte ratio （NLR） in patients with pneumonia， and there were different degrees of hysteresis effects， with the effect values reaching a maximum at lag03， lag03， lag0， lag03， lag03， respectively， which were 4.13% （95%CI： 0.43%‒7.84%）， 3.10% （95%CI： 0.24%‒5.97%）， 5.27% （95%CI： 3.12%‒7.42%）， 1.85% （95%CI： 0.36%‒3.34%）， and 2.53% （95%CI： 0.53%‒4.74%） for every 10 μg·m-3 of PM2.5. The changes in O3 concentration were associated with the elevation of peripheral blood PCT and ESR in patients with pneumonia， and their effect values all reached the maximum at lag01 d， every 1 μg·m-3 of O3 elevation increased by 0.38% （95%CI： 0.04%‒0.73%） and 0.47% （95%CI： 0.19%‒0.76%）， respectively. Stratified analyses showed that the associations of PM2.5 with peripheral blood CRP， ESR， NEU， and NLR in pneumonia patients were more significant in males， the elderly， and those with onset in the cold season； the associations of O3 with peripheral blood PCT and ESR in pneumonia patients were more significant in the elderly and those with onset in the warm season， and the peripheral blood CRP and PCT in female patients with pneumonia were more susceptible to the changes of O3. ConclusionShort-term exposure to atmospheric PM2.5 and O3 are positively associated with changes in inflammatory indicators in patients with pneumonia， and the effects of PM2.5 on patients with pneumonia are more extensive than those of O3， with a longer lag effect. In addition， elderly patients with pneumonia are more sensitive to air pollution， male patients with pneumonia are more sensitive to PM2.5， and female patients with pneumonia are more sensitive to O3. Cold and warm seasons can exacerbate the effects of PM2.5 and O3 on inflammatory indicators in patients with pneumonia， respectively， and the patients must be protected well.

ObjectiveTo learn the epidemiological features of foodborne diseases， and to provide scientific basis for disease control. MethodsThe monitoring data of foodborne diseases in Minhang from 2016 to 2020 were analyzed. Stool or swab specimens were collected to detect salmonella， Vibrio parahaemolyticus， Escherichia coli， Shigella， Campylobacter jejuni and norovirus. ResultsThe information of15 951 foodborne disease cases and 11 176 samples were collected， with the positive rate of 12.03%.The cases with diarrhea accounted for 99.90% of the total. The cases with fever accounted for 14.70% of the total. The cases with water stool accounted for 89.70% of the total. May to October were the epidemic periods of foodborne diseases in Minhang（79.78%）. The detection rate was the highest in the 30‒39 age group and cadre staff occupation（13.53%，13.49%）. The detection rates of foodborne bacteria and virus were 5.39% （Vibrio parahaemolyticus）， 3.25% （salmonella），1.44% （norovirus）， 1.06%（Escherichia coli）， 0.56% （Campylobacter jejuni）， 0.34% （mixed infection） and 0% （Shigella）. During this 5-year period， the positive rate of Vibrio parahaemolyticus decreased significantly， while the positive rate of salmonella and Escherichia coli and Campylobacter jejuni increased significantly. The main suspected food were aquatic products （29.44%）， meat （25.80%） and fruits （10.78%）. The main processing methods of suspected food were family workshop （41.12%） and restaurants （37.55%）. The total detection rate of the cases was the highest in the canteen， reaching 20.51%. ConclusionFoodborne disease cases have a seasonal peak. The positive detection of pathogens tends to be similar year by year. The main suspected food is aquatic products. The main resources of suspected food are family workshop， restaurants， and canteen. Targeted health education， supervision and management should be taken to prevent the occurrence of foodborne diseases and the outbreak of food poisoning

The bile acid-responsive G-protein-coupled receptor TGR5 is expressed in monocytes and macrophages, and plays a critical role in regulating inflammatory response. Our previous work has shown its role in promoting the progression of non-small cell lung cancer (NSCLC), yet the mechanism remains unclear. Here, using Tgr5-knockout mice, we show that TGR5 is required for M2 polarization of tumor-associated macrophages (TAMs) and suppresses antitumor immunity in NSCLC via involving TAMs-mediated CD8+ T cell suppression. Mechanistically, we demonstrate that TGR5 promotes TAMs into protumorigenic M2-like phenotypes via activating cAMP-STAT3/STAT6 signaling. Induction of cAMP production restores M2-like phenotypes in TGR5-deficient macrophages. In NSCLC tissues from human patients, the expression of TGR5 is associated with the infiltration of TAMs. The co-expression of TGR5 and high TAMs infiltration are associated with the prognosis and overall survival of NSCLC patients. Together, this study provides molecular mechanisms for the protumor function of TGR5 in NSCLC, highlighting its potential as a target for TAMs-centric immunotherapy in NSCLC.

ObjectiveTo determine the epidemiological characteristics and risk factors of a norovirus GII.17 outbreak in Minhang District of Shanghai in 2018， and provide evidence for prevention and control measures of norovirus infection. MethodsDescriptive epidemiological analysis was performed. In addition， a retrospective cohort study was conducted to determine the risk factors. ResultsFrom May 30th to June 1st of 2018， a total of 132 cases （126 clinical cases and 6 confirmed cases） were documented，with an attack rate of 29.20%（132/452）.All cases were children in a kindergarten， with the average age of 5 years and 43.9% being male. The cases were reported in all the classes， with no clustering by class or floor．The epidemic curve was characterized by a point source exposure， which was estimated to be probably between 7 AM on May 30thand 0：30 AM on May 31st. The retrospective cohort study showed that the attack rate significantly differed between the children who had taken and did not take the school lunch （RR=∞） on May 30th，and those who had taken and did not take seafood noodles （RR=4.11， 95%CI：1.09-15.55） （P<0.05）. Among a total of 73 specimens， six specimens collected in child cases and one specimen in an asymptomatic chef tested positive for GII.17 type of norovirus. In addition， one retained food specimen of seafood noodles was positive for Aeromonas hydrophila. Viral shedding in the asymptomatic chef remained over 30 days. ConclusionThe outbreak was caused by seafood noodles contaminated by norovirus. It warrants enhancement in the regulation of food safety in canteens and regular examination of norovirus infection in catering industry employees.

Objective To investigate aluminum content in commercially available flour products in Minhang District, Shanghai, and to assess the risk of dietary aluminum exposure among permanent residents in Minhang. Methods From 2018 to 2019, a total of 227 samples including fried flour products, steamed flour products, puffed products and baked flour products, were collected in Minhang District to detect the aluminum content. The food frequency table was used to investigate the consumption of flour foods by permanent residents in Minhang District and to assess population dietary aluminum exposure risk. Results The average content of aluminum in 227 kinds of flour products was 31.66 mg/kg, and the exceeding standard rate was 3.96%. The over-standard foods were all fried flour products, and the over-standard rate reached 10.47%. Moreover, the aluminum over standard rate of flour products produced by itinerant vendors and restaurants was significantly higher than that of flour products produced by supermarkets and manufacturers. The average dietary intake of aluminum in Minhang residents was 0.18 mg/kg per week, accounting for 9.03% of the provisional tolerable weekly intake (PTWI). The aluminum exposure of the population with high consumption of foods was 1.4 mg/kg per week, accounting for 69.90% of the PTWI. Among the four types of flour products, fried flour products had the highest contribution rate to aluminum exposure. The daily consumption of fried flour products in males was significantly higher than that in females (P<0.05), and the 18-34 age group was significantly higher than the 60 years old and above group (P<0.05). Conclusion The risk of the average dietary aluminum exposure of flour foods among Minhang residents is relatively low, but people with high consumption of foods would be confronted with increased health risks. It is necessary to strengthen the supervision on the use of aluminum-containing additives in itinerant vendors and restaurants, and actively advocate reducing the frequency and the consumption of fried flour products, thus reduce the exposure to the high risk of dietary aluminum in fried flour products

ObjectiveTo determine the optimal timing of antenatal taurine supplementation to improve neuron and neural stem cell proliferation in fetal rats with intrauterine growth restriction.Methods Twenty-five pregnant SD rats were randomly divided into five groups (five rats in each group): group A was the control group, group B to E were the fetal growth restriction (FGR) model groups with low-protein diet during the experiment, group C, D, and E were supplemented with taurine [300 mg/(kg·d)] at day 9, 11 and 15, respectively. The birth weight of newborn rats was measured after natural delivery. The rats with body weight two standard deviations lower than the average weight in group A were diagnosed as FGR. There were five litters of newborn rats in each group, and two were randomly selected from each litter, resulting in ten newborn rats in each group. Proliferating cell nuclear antigen (PCNA) and fatty acid binding protein 7 (FABP7) positive cell expression in newborn rat brain tissues were detected by immunohistochemistry. Single factor analysis of variance, LSD tests were used for statistical analysis.ResultsThe average birth weight of newborn rats in group A, B, C, D and E were (6.61±0.45), (4.65±0.23), (5.37±0.17), (5.74±0.21), and (5.00±0.24) g, respectively. Average birth weight was lower in group B than in group A (t=2.447), higher in group D and E than in group B (t=2.306 and 2.306), higher in group D than in group C and E (t=2.306 and 2.306), and the differences were statistically significant (allP0.05). The IOD in group D was higher than that in group E, and the difference was statistically significant (t=4.182,P<0.05).ConclusionsAntenatal taurine supplementation can promote neuron and neural stem cell proliferation in rats with FGR. The effect is most obvious on the 11th day of pregnancy, and may lead to the promotion of brain development.

<p><b>BACKGROUND</b>Vitamin D supplementation is believed to be beneficial in the treatment of patients with tuberculosis (TB), however, results from clinical trials have been inconclusive.</p><p><b>METHODS</b>We performed a systematic literature search across MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, Springer, EBSCO, ProQuest, HighWire Press, and Web of Science, published as of December 2013. We individually inspected citations and extracted data independently. We estimated pooled risk ratios (RR) and 95% confidence intervals (CI) using random-effect models. We also assessed risk of bias using the Jadad scale and the quality of the evidence using GRADE. We included all randomized controlled trials comparing vitamin D with or without standard TB therapy or placebo.</p><p><b>RESULTS</b>A total of five studies were analyzed in our meta analysis covering 841 newly-diagnosed TB cases. Patients receiving vitamin D supplementation had a 39% reduced risk of sputum smear or culture positive after six weeks of anti-TB treatment than those in the control group, although this is not statistically significant (pooled RR 0.61, 95% CI 0.24 to 1.56, P = 0.30). Apart from an increased serum vitamin D level in the supplement group after eight weeks of treatment there was no evidence of any additional adverse effects related to vitamin D.</p><p><b>CONCLUSIONS</b>The meta analysis results indicate that vitamin D supplementation does not seem to have any beneficial effect in the treatment of TB. Future rigorous randomized controlled trials are needed to explore whether the supplementation of vitamin D could shorten treatment duration and to confirm whether the polymorphisms of vitamin D receptor have any potentially beneficial effect.</p>
