Objective: To analyze the epidemiological characteristics and trends of other infectious diarrhea among children under 18 years old in Guangzhou City from 2014 to 2020, and to explore the correlation between climatic factors and the incidence of the disease, so as to provide reference for the early prevention of infectious diseases. Methods: The data of cases of other infectious diarrhea and meteorological data of children under 18 years old in Guangzhou City from 2014 to 2020 were collected through the Chinese Infectious Disease Reporting System and the Guangzhou Meteorological Bureau. The correlation between meteorological factors and the incidence of other infectious diarrhea was analyzed using negative binomial regression. Results: A total of 104 566 cases of other infectious diarrhea among children under 18 years old were reported in Guangzhou City from 2014 to 2020, with a male to female ratio of 1.48∶1. The incidence rate was the highest in 2017 (980.83 per 100 000) and the lowest in 2020 (388.22 per 100 000). The peak of incidence occurred from October to March of the following year. Children under 5 years old accounted for 87.95% of all cases. The number of cases of other infectious diarrhea was negatively correlated with the temperature of the previous 6 days ( IRR = -0.07 ), and positively correlated with the temperature difference on the day of onset ( IRR =0.02) (both P <0.05). It was also positively correlated with the wind speed of the previous 7 days ( IRR=0.07, P <0.05), but there was no statistically significant correlation with the relative humidity on the day of onset ( IRR=-0.00, P >0.05). Conclusions Low temperature, large temperature difference, and high wind speed can increase the risk of other infectious diarrhea. It is necessary to strengthen the prediction and early warning in conjunction with meteorological changes, and warn kindergartens and schools to enhance preventive measures against the clustering of other infectious diarrhea cases.

Objective:To evaluate the guiding value of ultrasound-guided selective nerve root block in the surgical treatment of multilevel lumbar degeneration.Methods:Retrospective case-control study was used. Clinical data of 47 patients with multi-level lumbar degeneration who underwent decompression surgery in Honghui Hospital, Xi′an Jiaotong University from January 2019 to December 2021 were retrospectively analyzed. They were divided into nerve root block group ( n=22)and non-nerve root block group( n=25) according to whether ultrasound-guided selective nerve root block was performed before decompression surgery. The operation time, intraoperative blood loss, number of decompression laminae, postoperative drainage volume and length of stay of the two groups were recorded and compared. The visual analogue scale of low back pain, the visual analogue scale (VAS) of leg pain, the Japanese orthopaedic association (JOA) score and Oswestry disability index (ODI) score were all compared before surgery and during follow-up between the two groups. Measurement data with normal distribution were represented as mean±standard deviation( ± s), and the comparison between groups was conducted using the paired t-test. Chi-square test was used for counting data. Results:All 47 patients successfully completed the operation without any serious complications such as neurovascular injury. All patients were followed up for (27.6±7.5)months. In the nerve root block group, the operation time, intraoperative blood loss, number of decompression laminae, postoperative drainage volume and hospital stay were (90.5±12.6) min, (110.5±15.8) mL, 1.2±0.8, (85.6±15.8) mL, (6.2±2.8) d, respectively. In the non-root block group, they were (190.6±25.5) min, (450.5±24.8) mL, 3.8±1.6, (210.5±16.8) mL, (9.5±2.2) d, respectively. The above indexes in the nerve root closure group were less than those in the non-root closure group, and the difference was significant between the two groups ( P< 0.05). The scores of VAS of low back pain and leg pain, JOA and ODI in both groups were significantly improved after surgery and during the follow-up period when compared with those of pre-operation ( P< 0.05). The VAS scores of low back pain on the 3rd day, 6 months after operation and at the last follow-up in the nerve block group were 3.2±1.4, 1.4±0.8, 0.5±0.2, the JOA scores were 15.8±4.3, 21.3±5.6, 25.6±1.4, and the ODI scores were 50.6±10.3, 22.8±7.8, 16.8±4.2, respectively. The VAS scores of low back pain on the 3rd day, 6 months after operation and at the last follow-up in the non-nerve block group were 5.1±1.8, 3.4±1.2, 1.8±0.5, the JOA scores were 14.1±4.8, 20.5±3.2, 24.2±1.8, and the ODI scores were 60.5±9.8, 31.6±8.2 and 21.3±5.5, respectively. The difference between the two groups was statistically significant ( P<0.05). However, there was no statistical difference in the VAS scores of leg pain between the two groups after surgery and during follow-up ( P>0.05). At the last follow-up, the internal fixation position of the two groups was good, no loosening and displacement, and bone graft fusion was good. Conclusion:For patients with multi-level lumbar degeneration, ultrasound-guided selective nerve root block before surgery can identify the responsible segment, and selective decompression and fusion based on this can effectively reduce surgical trauma, while improving patients′ back and leg pain and physical function, which has important surgical guidance value.

Objective:To observe and evaluate the clinical efficacy and safety of albumin-bound paclitaxel as first-line treatment for patients with advanced pancreatic cancer in China, and to explore the prognosis-related molecules in pancreatic cancer based on next-generation sequencing (NGS) of tumor tissues.Methods:From December 2018 to December 2020, patients with locally advanced or metastatic pancreatic cancer were recruited to accept albumin-bound paclitaxel as first-line treatment in the oncology departments of 24 hospitals in East China. The primary endpoints were overall survival (OS) and treatment related adverse events, and the secondary endpoint was progression-free survival (PFS). Adverse effects were graded using Common Terminology Criteria for Adverse Events 5.0 (CTCAE 5.0). NGS sequencing on the primary or metastatic tissue samples of pancreatic cancer obtained through surgical resection or biopsy was performed.Results:This study recruited 229 patients, including 70 patients with locally advanced pancreatic cancer (LAPC) and 159 patients with metastatic pancreatic cancer (mPC). The disease control rate was 79.9% and the objective response rate is 36.3%.The common adverse effects during treatment were anaemia (159 cases), leucopenia (170 cases), neutropenia (169 cases), increased aminotransferases (110 cases), and thrombocytopenia (95 cases), and the incidence of grade 3-4 neutropenia is 12.2% (28/229). The median follow-up time was 21.2 months (95% CI: 18.5-23.1 months). The median PFS (mPFS) was 5.3 months (95% CI: 4.37-4.07 months) and the median OS (mOS) was 11.2 months (95% CI: 9.5-12.9 months). The mPFS of patients with LAPC was 7.4 months (95% CI: 6.6-11.2 months), and their mOS was 15.5 months (95% CI: 12.6-NA months). The mPFS of patients with mPC was 3.9 months (95% CI: 3.4-5.1 months), and their mOS was 9.3 months (95% CI: 8.0-10.8 months). Multivariate Cox regression analysis showed that clinical stage ( HR=1.47, 95% CI: 1.06-2.04), primary tumor site ( HR=0.64, 95% CI: 0.48-0.86), Eastern Cooperative Oncology Group Performance Status (ECOG PS) score ( HR=2.66, 95% CI: 1.53-4.65), and whether to combine radiotherapy ( HR=0.65, 95% CI: 0.42-1.00) were independent influencing factors for the PFS of these patients. The primary tumor site ( HR=0.68, 95% CI: 0.48-0.95), ECOG score ( HR=5.82, 95% CI: 3.14-10.82), and whether to combine radiotherapy ( HR=0.58, 95% CI: 0.35-0.96) were independent influencing factors of the OS of these patients. The most frequent gene mutations in these advanced stage pancreatic patients were KRAS (89.66%), TP53 (77.01%), CDKN2A (32.18%), and SMAD4 (21.84%) by NGS of tumor tissues from 87 pancreatic cancer patients with sufficient specimens. Further analysis revealed that mutations in CDKN2B, PTEN, FGF6, and RBBP8 genes were significantly associated with an increased risk of death ( P＜0.05). Conclusion:Albumin-bound paclitaxel as first-line treatment demonstrated feasible anti-tumor efficacy and manageable safety for patients with advanced pancreatic cancer in China.

Objective:To explore the efficacy of consolidation chemotherapy after radical radiotherapy and chemotherapy in stage Ⅲ-ⅣA esophageal squamous cell carcinoma (ESCC) patients in the real world.Methods:The clinical data of 139 patients with stage Ⅲ-ⅣA ESCC who underwent radical radiotherapy and chemotherapy from January 1, 2018 to December 31, 2022 in Hefei Cancer Hospital, Chinese Academy of Sciences were retrospectively analyzed. Patients were divided into a control group ( n=85) and a consolidation chemotherapy group ( n=54) based on whether they underwent consolidation chemotherapy after radical radiotherapy and chemotherapy. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) between the two groups were compared. The Kaplan-Meier method was used to draw survival curves and log-rank tests were conducted. The Cox proportional risk model was used for univariate and multivariate analysis. Results:The ORR of the control group and the consolidation chemotherapy group were 44.71% (38/85) and 66.67% (36/54), respectively, with a statistically significant difference ( χ2=5.54, P=0.018) ; the DCR were 70.59% (60/85) and 87.04% (47/54), respectively, with a statistically significant difference ( χ2=5.04, P=0.025). The median PFS of the two groups of patients were 9.0 and 13.1 months, respectively, with a statistically significant difference ( χ2=12.74, P<0.001) ; the median OS were 15.0 and 20.6 months, respectively, with a statistically significant difference ( χ2=24.75, P<0.001). The median OS of ESCC patients in two subgroups of cT 3-4N 1-3M 0 were 16.0 and 30.8 months, respectively, with a statistically significant difference ( χ2=23.49, P<0.001). Univariate analysis showed that tumor length ( HR=1.57, 95% CI: 1.04-2.36, P=0.032), objective response ( HR=0.08, 95% CI: 0.04-0.17, P<0.001), and consolidation chemotherapy ( HR=0.32, 95% CI: 0.20-0.51, P<0.001) were all influencing factors for OS in ESCC patients undergoing radical radiotherapy and chemotherapy in stages Ⅲ-ⅣA. Multivariate analysis showed that tumor length ( HR=1.59, 95% CI: 1.05-2.43, P=0.030), objective response ( HR=0.05, 95% CI: 0.02-0.10, P<0.001), and consolidation chemotherapy ( HR=0.22, 95% CI: 0.13-0.36, P<0.001) were all independent influencing factors for OS in stage Ⅲ-ⅣA ESCC patients undergoing radiotherapy and chemotherapy. In terms of safety, the consolidation chemotherapy group experienced 7 adverse reactions mainly gastrointestinal reaction and leukopenia, including 5 cases of grade 1-2 and 2 cases of grade 3-4; 22 cases of adverse reactions occurred in the control group including 16 cases of grade 1-2 and 6 cases of grade 3-4 mainly including neutropenia, thrombocytopenia, anemia and digestive tract reaction. The incidence rates of adverse reactions in the two groups were 12.96% (7/54) and 25.88% (22/85), respectively, with no statistically significant difference ( χ2=3.34, P=0.068) . Conclusion:After radical radiotherapy and chemotherapy, consolidation chemotherapy can significantly improve the prognosis of stage Ⅲ-ⅣA ESCC patients, and the overall adverse reactions are controllable.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To assess respondents' understanding of the Physical Activity Questionnaire for Chronic Kidney Disease (CKD-PAQ) in Chinese and revise the items.Methods:The CKD-PAQ was sinicized according to the FACIT translation model to form a preliminary version. Using the purposive sampling method, 40 patients with chronic kidney disease from Shenzhen Traditional Chinese Medicine Hospital were selected as respondents for three rounds of cognitive interviews from July to August 2023. Targeted content analysis was used to understand the level of understanding of the initial version of the questionnaire. Based on the respondents' suggestions, the questionnaire's final version was obtained after discussing and negotiating the questionable items.Results:The CKD-PAQ contained four dimensions and 31 items. A total of 22 questions were identified in three rounds of interviews. The results of the first round of interviews show that 13 questions need to be revised in terms of understanding and expression, the results of the second round of interviews show that eight questions need to be revised in terms of understanding and expression, the results of the third round of interviews showed that the language understanding of the revised Chinese version was consistent with the original questionnaire.Conclusions:Cognitive interviews can improve respondents' understanding of the questionnaire and identify issues that are difficult to identify during the localization process, thus improving the accuracy of the questionnaire.

Objective:To analyze the influence of midwifeled accompanyon the psychological status and delivery outcomes of gestational diabetes patients, and to provide reference for the implementation of clinical intervention programs for gestational diabetes patients.Methods:A semi-randomized controlled trial was adopted.Convenience sampling method was used to select 120 gestational diabetes patients admitted to Langfang People′s Hospital from March 2021 to September 2023, and they were divided into control group and experimental group according to the admission order. Both groups were given intraspinal delivery analgesia, while the control group was combined with routine midwifery management, and the experimental group was combined with a midwife led accompany. Intervention lasted until 2 h postpartum in both groups, and follow-up for 1 month. The delivery indicators, psychological status, delivery outcome and satisfaction of the two groups were compared.Results:Finally, 120 gestational diabetes patients were included, 60 patients in the control group, aged (28.73 ± 2.79) years, and 60 patients in the experimental group, aged (27.98 ± 1.09) years. The first and second stages of labor in the experimental group were (416.35 ± 29.87) and (60.95 ± 7.44) min, respectively, which were shorter than (501.33 ± 37.59) and (80.28 ± 8.95) min in the control group, and the differences were statistically significant ( t = 13.71, 12.87, both P<0.05). The blood glucose during delivery and 2 h postpartum hemorrhage was (6.81 ± 0.10) mmol/L and (236.18 ± 37.58) ml, respectively, lower than (7.48 ± 0.45) mmol/L and (325.70 ± 59.88) ml in the control group, the differences were statistically significant ( t = 11.26, 9.81, both P<0.05). After 1 month of follow-up, the scores of Self-rating Anxiety Scale and Self-rating Depression Scale of the experimental group were (30.86 ± 2.55) and (21.45 ± 2.67) points, which were lower than (42.19 ± 3.86) and (42.97 ± 3.15) points in the control group, and the scores of Psychological Resilience Scale were (71.22 ± 6.54) points, which was higher than that of the control group (55.38 ± 6.06) points, the differences were statistically significant ( t = 18.97, 40.37, 13.76, all P<0.05). After intervention, the incidence rates of lateral resection and postpartum hemorrhage in the experimental group were 28.3%(17/60) and 5.0%(3/60), respectively, lower than 48.3%(29/60) and 18.3%(11/60) in the control group, and the total satisfaction rate of the experimental group was 93.3%(56/60), higher than 80.0% (48/60) of the control group. The differences were statistically significant ( χ2 = 5.08, 5.18, 4.62, all P<0.05). Conclusions:The midwife led accompany could shorten the labor process of gestational diabetes patients, reduce their blood glucose during delivery and the amount of blood 2 h postpartum, and improve their psychological status and delivery outcomes, which was conducive to improving patient satisfaction.

Objective:To explore the efficacy of secondary targeted percutaneous vertebroplasty (PVP) for the treatment of refracture of injured vertebrae after vertebral augmentation for osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective case series study was performed on the clinical data of 25 patients with refracture of injured vertebrae after vertebral augmentation for OVCF admitted to Honghui Hospital, Xi′an Jiaotong University from January 2019 to January 2022, including 10 males and 15 females, aged 62-86 years [(73.8±5.2)years]. The fractured segments involved T 10 in 1 patient, T 11 in 2, T 12 in 10, L 1 in 10 and L 2 in 2. All the patients were treated with secondary targeted PVP. The operation time and the amount of bone cement injected were recorded. The visual analogue scale (VAS) of lower back, Oswestry disability index (ODI), vertebral body index (VBI) and kyphotic angle (KA) were compared before surgery, at 1 day, 6 months after surgery and at the last follow-up. Odom criteria were used to evaluate the efficacy of the surgical procedure at the last follow-up. The intraoperative bone cement leakage and new vertebrae fracture during follow-up were observed. Results:All the patients were followed up for 23-59 months [(36.8±7.6)months]. The operation time was 35-60 minutes [(42.6±5.2)minutes], with the amount of bone cement injected for 3-5 ml [(3.6±0.8)ml]. The VAS scores of lower back at 1 day, 6 months after surgery and at the last follow-up were 3.1(2.0, 4.0)points, 1.7(1.0, 2.0)points and 0.6(0.0, 1.0)points respectively, significantly lower than 7.6(7.0, 9.0)points before surgery ( P<0.01), and a statistically singnificant decrease was found over follow-up time ( P<0.01). The ODI values at 1 day, 6 months after surgery and at the last follow-up were (49.5±5.9)%, (28.5±4.6)% and (19.2±4.8)% respectively, significantly lower than (78.8±6.8)% before surgery ( P<0.01), and a statistically singnificant decrease was found over follow-up time ( P<0.01). The VBI values at 1 day, 6 months after surgery and at the last follow-up were (76.6±4.5)%, (76.3±4.0)% and (76.1±3.8)% respectively, significantly higher than (58.9±5.8)% before surgery ( P<0.01), while there were no significant differences among those at 1 day, 6 months after surgery and at the last follow-up ( P>0.05). The KA values at 1 day, 6 months after surgery and at the last follow-up were (12.4±2.7)°, (12.6±2.5)° and (12.8±2.9)° respectively, significantly lower than (20.8±3.6)° before surgery ( P<0.01), while there were no significant differences among those at 1 day, 6 months after surgery and at the last follow-up ( P>0.05). According to the Odom criteria, 20 patients were rated excellent and 5 good at the last follow-up, with an excellent and good rate of 100%. Intraoperative asymptomatic bone cement leakage occurred in 3 patients (12%), including 2 with intervertebral leakage and 1 with lateral vertebral leakage. No adjacent vertebral body or other vertebral fracture was observed during the follow-up. Conclusions:For patients with refracture of injured vertebrae after vertebral augmentation for OVCF, the secondary targeted PVP has advantages of attenuation of the lower back pain, improvement of the quality of life, restoration of the height of refractured vertebrae, correction of the local kyphosis, and a low incidence of complications.

Crohn’s disease is a chronic intestinal inflammatory disorder of unknown etiology. Although the pharmacotherapies for Crohn’s disease are constantly updating, nutritional support and adjuvant therapies have recently gained more attention. Due to advancements in clinical nutrition, various clinical nutritional therapies are used to treat Crohn’s disease. Doctors treating inflammatory bowel disease can now offer several diets with more flexibility than ever. The Crohn’s disease exclusion diet is a widely used diet for patients with active Crohn’s disease. The Crohn’s disease exclusion diet requires both exclusion and inclusion. Periodic exclusion of harmful foods and inclusion of wholesome foods gradually improves a patient’s nutritional status. This article reviews the Crohn’s disease exclusion diet, including its structure, mechanisms, research findings, and clinical applications.
