Objective: To explore the effects of different concentrations of glucose solution on the survival of Aedes albopictus and Culex pipiens pallens larvae, the attraction to mosquitoes and egg-laying behaviors, so as to provide the reference for developing mosquito control technology based on sugar bait. Methods: White porcelain bowls were filled with 100 mL of 3%, 5%, 8%, 10% and 15% glucose solutions. Ten of fourth instar larvae of Aedes albopictus or Culex pipiens pallens were added to each bowl, and the survival of larvae was recorded after 2, 4, 6, 24, 48 and 72 hours. Egg-laying cups containing 5%, 8% and 15% glucose solution were put in mosquito cages containing fully blooded female mosquitoes of Aedes albopictus and Culex pipiens pallens (50 mosquitoes each), and the total number of eggs laid in 72 hours was observed. The analogous site room was filled with fully blooded and starved female mosquitoes of Aedes albopictus and Culex pipiens pallens (100 mosquitoes each), and simple mosquito control buckets containing 5% and 8% glucose solution and black sticky insect plates. The number of mosquitoes and eggs was observed after 6 days. All the above experiments were repeated 3 times using dechlorinated water as the control. Results: The 72 hour corrected mortality rates of Aedes albopictus and Culex pipiens pallens larvae gradually increased with the increase of glucose concentration. The glucose solution with 5% and higher concentrations was not suitable for mosquito larvae to survive. The attraction of egg-laying behaviors to Aedes albopictus and Culex pipiens pallens gradually decreased with the increase of glucose concentration. The effects were similar between 5% and 8% glucose solution, with the averages of 686.67 and 682.33 eggs for Aedes albopictus, and 3.00 and 2.33 egg rafts for Culex pipiens pallens. In analogous site room, there were 93.33, 105.00 and 130.33 adult mosquitoes captured on average in the control group, 5% and 8% glucose solution groups, respectively, with 8% glucose solution group more attractive to adult mosquitoes than the control group (F=3.283, P=0.030); there were 70.33, 55.33 and 63.00 Aedes albopictus eggs (eggs counts+larvae counts) on average, respectively, with statistically significant differences among the three groups (H=6.761, P=0.034). Conclusion Glucose solution with concentration of 5% or higher can effectively inhibit the survival of Aedes albopictus and Culex pipiens pallens larvae, and attractive to adult mosquitoes and egg-laying behavoirs.

Objective: To investigate the factors affecting human papillomavirus (HPV) vaccination behaviors among gynecological outpatients based on extended unified theory of acceptance and use of technology (UTAUT2), so as to provide insights into the development of HPV vaccination behavioral interventions. Methods: Patients at ages of 45 years and younger that were admitted to the outpatient department of gynecological of Shanxi Provincial People's Hospital from October 2021 to August 2022 were recruited, and the factors affecting HPV vaccination behaviors were identified using UTAUT2. Results: A total of 431 female outpatients were enrolled, including 163 patients at ages of 36 to 45 years (37.82%), 272 cases with an educational level of college degree and above (63.11%) and 253 patients with per capita monthly household income of more than 3 000 Yuan (58.70%). The coverage of HPV vaccination was 24.36%, and the main cause of non-vaccination was difficulty in high-valent HPV vaccine appointment. Price value, social impact and efficacy expectation posed a positive impact on HPV vaccination behaviors via intention of vaccination (β=0.11, 0.08, 0.07, all P<0.05) and intention of vaccination and effort expectancy (β=0.10, 0.07, 0.06, all P<0.05), and effort expectancy played a mediating effect between intention of vaccination and vaccination behaviors (β=0.28, P<0.05). Conclusion Efficacy expectation, social impact, price value, intention of vaccination and effort expectancy may positively affect HPV vaccination behaviors.

ObjectiveTo observe the effect of the enhanced external counterpulsation （EECP） combined with drug on social function and efficacy in patients with depressive episodes， so as to provide references for the treatment of depressive episodes. MethodsA total of 66 hospitalized patients who was in hospital at department of psychiatry of the Second Xiangya Hospital of Central South University， met the criteria of Diagnostic and Statistical Manual of Mental Disorders，fifth edition（DSM-5） diagnosis of depressive episode or bipolar disorder depressive episode from May 2019 to March 2020 were included by simple random sampling. The participants were divided into study group （n=36） and control group （n=30） according to the random number table method. Both groups received conventional drug treatment， and the study group recieved the EECP intervention at same time. The Depression symptoms and social function were assessed before and after treatment by using Hamilton Depression Scale-24 item （HAMD-24） and Sheehan Disability Scale （SDS）. Treatment efficacy of the two groups was compared. ResultsAfter the intervention， the HAMD-24 and SDS scores in both groups were lower than those before treatment， the differences were statistically significant （t=8.149， 5.791， 8.016， 3.488， P˂0.01）. And the SDS score of the study group was siginficantly lower than that of the control group （t=-3.008， P<0.05）. The total effective rate of treatment in the study group was higher than that of the control group， and the difference was statistically significant （90.63% vs. 63.33%， χ²=8.725， P˂0.05）. ConclusionEECP therapy combined with drug has better efficacy on the patients with depressive episodes， and it can improve social function effectively.

Exosomes are membranous vesicles secreted by most eukaryotic cells, which are approximately 30-150 nm in diameter and contain RNA, proteins and lipids closely related to their function and origin, playing an important role in cell-to-cell communication. It can promote tumor progression by promoting the proliferation and migration of tumor cells, improving the tumor microenvironment and inhibiting the immune response. In addition, exosomes are expressed at high levels in certain tumors and can be used as predictors of cancer for early diagnosis. It can also be used as a carrier to carry targeted drugs to the local tumor to exert an inhibitory effect.

Pyroptosis is a type of programmed cell death distincted from apoptosis and necrosis, which is accompanied by the lysis of cell membranes and the release of cell contents. Pyroptosis occurs as mediated by Gasdermin protein family and is dependent on the activity of caspase. GSDME is one of the most important members of the Gasdermin protein superfamily. GSDME-mediated pyroptosis relies on the activity of caspase-3. In recent years, with further research on pyroptosis, the mechanism of GSDME-induced pyroptosis is becoming clear. Numerous studies have shown that GSDME-mediated pyroptosis plays an important role in the occurrence and development of tumors, as well as chemotherapy resistance. However, GSDME-mediated pyroptosis has no specificity and can induce pyroptosis of normal cells in the body while inducing tumor cell pyroptosis, thus causing different degrees of damage to various organs of the body. Further study on the mechanism of GSDME-induced pyroptosis, the role of GSDME in malignant tumors and the adverse reactions of chemotherapy can provide new ideas for tumor monitoring, treatment and prognosis judgment.

Clinical and endoscopic data of 6 patients with colorectal mucosa associated lymphoid tissue (MALT) lymphoma who were diagnosed by endoscopy in the Digestive Endoscopy Center of Jiangsu Province Hospital of Chinese Medicine from January 2015 to June 2021 were retrospectively analyzed. There were 2 males and 4 females with aged from 62 to 87 years. The lesions were located in rectum in 3 cases, transverse colon in 1 case, sigmoid colon in 1 case, and sigmoid colon and rectum in 1 case. There were 1 case of polyposis type, 2 cases of inflammation type, and 3 cases of submucosal tumor type. The "tree-like appearance (TLA)" found in 5 cases. Endoscopic resection, surgery combined with chemotherapy, Helicobacter pylori eradication and follow-up were performed on 2, 1, 1 and 2 cases, respectively. Five cases had a good prognosis after 21-73 months follow-up, and 1 case had lost to follow-up. No recurrence was found in endoscopic and imaging review. Colorectal MALT lymphoma should be considered when colonoscopy detects a submucosal lesion with TLA sign on the left colon. Endoscopic resection has the potential to be a first-line treatment in the context of early diagnosis.

Objective:To investigate the clinical efficacy of intraspinal analgesia, pudendal nerve block anesthesia and modified perineal protection in combination in midwifery.Methods:A total of 160 primiparous women who were subjected to full-term vaginal delivery in Suqian Hospital of Nanjing Drum Tower Hospital Group between January 2019 and January 2021 were included in this study. They were randomly assigned to undergo either bilateral pudendal nerve block combined with modified perineal protection (control group, n = 80) or intraspinal analgesia, pudendal nerve block anesthesia and modified perineal protection in combination (observation group, n = 80). Each clinical index was compared between the control and observation groups. Results:Duration of labor in the observation group was significantly shorter than that in the control group [(7.23 ± 2.11) hours vs. (9.35 ± 3.79) hours, t = 4.27, P < 0.05). Cesarean section rate in the observation group was significantly lower than that in the control group [8.7% (7/80) vs. 52.5% (42/80), χ 2 = 17.18, P < 0.05]. Incidence of perineal tears in the observation group was significantly lower than that in the control group [8.7% (7/80) vs. 32.5% (26/80), χ 2 = 15.48, P < 0.05]. Third-degree perineal tears occurred in neither group. Time of postpartum off-bed ambulation and length of postpartum hospital stay in the observation group were (1.37 ± 0.13) days and (3.22 ± 0.31) days, respectively, which were significantly shorter than those in the control group [(2.52 ± 0.22) days, (5.23 ± 0.62) days, t = 25.90, 25.94, both P < 0.05). The incidence of complications in the observation group was significantly lower than that in the control group [7.5% (6/80) vs. 23.7% (19/80), χ 2 = 8.01, P < 0.05]. There were no significant differences in incidence of neonatal asphayxia, 2-hour postpartum hemorrhage and postpartum hemorrhage between the two groups (all P > 0.05). Conclusion:During midwifery of full-term vaginal delivery, combined application of intraspinal analgesia, bilateral pudendal nerve block anesthesia and modified perineal protection can shorten duration of labor and decrease cesarean section rate.

Objective:To investigate the effects of a perioperative whole course composite thermal insulation strategy on complications of cesarean section, maternal coagulation function and serum inflammatory indexes.Methods:A total of 250 pregnant women who were subjected to cesarean section in Zhoushan Hospital between June 2020 and August 2021 were included in this study. The 125 pregnant women who gave birth using a routine simple thermal insulation strategy from June to November 2020 were assigned to the routine simple thermal insulation group, and those who gave birth using a perioperative whole course composite thermal insulation strategy were assigned to whole course composite thermal insulation group. Two groups of pregnant women underwent cesarean section under subarachnoid block. Volume of intraoperative blood loss was recorded. The incidence of complications such as shivering and postoperative infection was calculated. Platelet count, prothrombin time, activated partial thromboplastin time, thrombin time measured before surgery and 48 hours after surgery were compared between the two groups. Peripheral blood white blood cell count, neutrophil count (N%), C-reactive protein, procalcitonin, interleukin-6 measured 48 hours after surgery were compared between the two groups.Results:Volume of intraoperative blood loss in the whole course composite thermal insulation group was significantly lower than that in the routine simple thermal insulation group [(393.84 ± 79.78) mL vs. (434.80 ± 123.49) mL, t = 3.11, P < 0.05). The incidence of shivering and postoperative infection in the whole course composite thermal insulation group was 10.4% (13/125) and 7.2% (9/125), respectively, which was significantly lower than that in the routine simple thermal insulation group [25.6% (32/125), 18.4% (23/125), χ 2 = 9.78, 7.02, both P < 0.05]. At 48 hours after surgery, prothrombin time, activated partial thromboplastin time, thrombin time in the whole course composite thermal insulation group were (10.28 ± 0.48) seconds, (26.97 ± 2.27) seconds, and (14.09 ± 1.36) seconds, respectively, which were significantly shorter than those in the routine simple thermal insulation group [(11.71 ± 0.27) seconds, (27.96 ± 2.25) seconds, (15.91 ± 1.09) seconds, t = 7.34, 3.43, 11.66, all P < 0.05]. At 48 hours after surgery, white blood cell count, neutrophil count, C-reactive protein, procalcitonin, and interleukin-6 in the whole course composite thermal insulation group were (10.38 ± 2.38) ×10 9/L,(0.79 ± 0.06), (52.79 ± 20.73) mg/L, (0.13±0.42) μg/L, and (55.73 ± 24.38) ng/L, respectively, which were significantly lower than those in the routine simple thermal insulation group [(12.24 ± 7.05) × 10 9/L, 0.81 ± 0.05, (65.38 ± 25.92) mg/L, (0.20 ± 0.97) μg/L, (76.22 ± 39.08) ng/L, t = 2.79, 2.92, 4.24, 8.12, 4.97, all P < 0.05]. Conclusion:Perioperative whole course composite thermal insulation strategy can improve the coagulation function of pregnant women who are subjected to cesarean section under subarachnoid block, reduce volume of intraoperative blood loss, and decrease incidence of shivering, inflammatory reaction, and postoperative infection.

Objective:To analyze the risk factors of pelvic infection after gynecological malignant tumor surgery and construct a predictive model.Methods:The convenient sampling method was used to collect the clinical data of 278 patients who underwent gynecological malignant tumor surgery in Shanxi Provincial People's Hospital from June 2018 to June 2020. According to the occurrence of postoperative pelvic infection, the patients were divided into the infection group ( n=29) and the non-infection group ( n=249) . Univariate and binomial Logistic regression analysis was used to investigate the risk factors of pelvic infection after gynecological malignant tumor surgery, and ROC curve was used to analyze the predictive value of the prediction model. Results:The incidence of pelvic infection in 278 patients with gynecological malignancies after surgery was 10.43% (29/278) . Binary logistic regression analysis showed that whether there were diabetes, chronic pelvic pain, history of preoperative pelvic infection and operation method, operation duration, and hospital stay were the influencing factors of pelvic infection after gynecological malignant tumor surgery ( P<0.05) . ROC curve analysis showed that diabetes mellitus, chronic pelvic pain, history of preoperative pelvic infection, surgical method, surgical duration and length of hospital stay all had certain predictive value for pelvic infection after gynecological malignant tumor surgery, while the predictive value of combined application was higher than that of each index alone. The area under the ROC curve was 0.821 (95% CI: 0.729-0.915) , and the accuracy was 0.817. Conclusions:The presence of diabetes mellitus, chronic pelvic pain, preoperative history of pelvic infection, surgical method, duration of surgery and length of hospital stay are the influential factors for pelvic infection after gynecological malignant tumor surgery. The combined prediction model established based on the above factors has good prediction ability.

Objective: To apply DNA barcoding to identifying the rodents in Zhejiang Province. Methods : Rodents were captured from Jiashan,Longyou,Yunhe and Ninghai counties in Zhejiang Province. The DNA was extracted from ears of rodent samples,and was amplified and sequenced with mitochondrial cytochrome C oxidase subunit I（COI）genes. The obtained sequences were compared with the related sequences in GenBank,and neighbour-joining evolutionary tree was constructed. Then the results by DNA barcoding and by morphological identification were compared. Results : A total of 22 COI gene samples were amplified. The evolutionary tree constructed by 18 samples was consistent with the morphological identification results and 4 samples were different：Suncus murinus should be Crocidura lasiura,infant rats of Rattus losea and Rattus tanezumi was re-identified as Rattus rattus,infant rats of Microtus fortis（sample number：NH-1）needs further identification. Conclusion DNA barcoding can effectively correct the errors of morphological identification,thus combining the two methods could improve the accuracy of rodent identification.
