Objective Data mining technology was used to mine the medication rules of the prescriptions used in the treatment of pediatric atopic dermatitis by Chinese medical master XUAN Guo-Wei.Methods The medical records of effective cases of pediatric atopic dermatitis treated by Professor XUAN Guo-Wei at outpatient clinic were collected,and then the medical data were statistically analyzed using frequency statistics,association rule analysis and cluster analysis.Results A total of 242 prescriptions were included,involving 101 Chinese medicinals.There were 23 commonly-used herbs,and the 16 high-frequency herbs(frequency＞100 times)were Glycyrrhizae Radix et Rhizoma,Saposhnikoviae Radix,Glehniae Radix,Perillae Folium,Ophiopogonis Radix,Cynanchi Paniculati Radix et Rhizoma,Microctis Folium,Dictamni Cortex,Scrophulariae Radix,Coicis Semen,Cicadae Periostracum,Lilii Bulbus,Rehmanniae Radix,Kochiae Fructus,Sclerotium Poriae Pararadicis,and Euryales Semen.The analysis of the medicinal properties showed that most of the herbs were sweet and cold,and mainly had the meridian tropism of the spleen,stomach and liver meridians.The association rule analysis yielded 24 commonly-used drug combinations and 20 association rules.Cluster analysis yielded 2 core drug combinations.Conclusion For the treatment of pediatric atopic dermatitis,Professor XUAN Guo-Wei focuses on the clearing,supplementing and harmonizing therapies,and the medication principle of"supporting the healthy-qi to eliminate the pathogen,and balancing the yin and yang"is applied throughout the treatment.

Bufonis Venenum, an animal medicinal material, is widely used for treating cardiovascular diseases and pain induced by rheumatics or malignant tumors. In view of the high activity and high toxicity, it is of great significance to pay attention to the quality control of Bufonis Venenum to ensure the safety and effectiveness of its preparations. China's drug standards involve 102 preparations(474 batch numbers) containing Bufonis Venenum approved for sale, including 14 preparations in the Chinese Pharmacopoeia(2020 edition) and 68 preparations in the standards issued by the Ministry of Health Drug Standard of the People's Republic of China. Bufonis Venenum is mostly used in pill and powder preparations in the form of raw powder, with the main functions of clearing heat, removing toxin, relieving swelling and pain, replenishing qi, activating blood, opening orifice, and awakening brain. Except the high level of quality control for Bufonis Venenum in the preparations in the Chinese Pharmacopoeia(2020 edition), the quality control standards of Bufonis Venenum in other preparations are low or even absent. Therefore, it is urgent to conduct research on the improvement of quality standards for the preparations containing Bufonis Venenum. This study retrieved the reports focusing on the quality evaluation and quality control of the preparations containing Bufonis Venenum from CNKI, PubMed, and Web of Science. Qualitative and quantitative analysis methods for 64 preparations containing Bufonis Venenum have been reported, mainly including thin-layer chromatography, HPLC fingerprint, and multi-component content determination. The index components mainly involved bufadienolides, such as gamabufalin, arenobufagin, bufotalin, bufalin, cinobufagin, and resibufogenin. According to the literature information, this paper suggests that attention should be paid to the correlations between the analysis methods and detection indexes of medicinal materials, decoction pieces and preparations, the monitoring of indole alkaloids, and the content uniformity inspection for further improving the quality standards for the preparations containing Bufonis Venenum.

Objective: To investigate the clinical features and short-term prognosis of patients with SARS-CoV-2 infection associated acute encephalopathy (AE). Methods: Retrospective cohort study. The clinical data, radiological features and short-term follow-up of 22 cases diagnosed with SARS-CoV-2 infection associated AE in the Department of Neurology, Beijing Children's Hospital from December 2022 to January 2023 were retrospectively analyzed. The patients were divided into cytokine storm group, excitotoxic brain damage group and unclassified encephalopathy group according to the the clinicopathological features and the imaging features. The clinical characteristics of each group were analyzed descriptively. Patients were divided into good prognosis group (≤2 scores) and poor prognosis group (>2 scores) based on the modified Rankin scale (mRS) score of the last follow-up. Fisher exact test or Mann-Whitney U test was used to compare the two groups. Results: A total of 22 cases (12 females, 10 males) were included. The age of onset was 3.3 (1.7, 8.6) years. There were 11 cases (50%) with abnormal medical history, and 4 cases with abnormal family history. All the enrolled patients had fever as the initial clinical symptom, and 21 cases (95%) developed neurological symptoms within 24 hours after fever. The onset of neurological symptoms included convulsions (17 cases) and disturbance of consciousness (5 cases). There were 22 cases of encephalopathy, 20 cases of convulsions, 14 cases of speech disorders, 8 cases of involuntary movements and 3 cases of ataxia during the course of the disease. Clinical classification included 3 cases in the cytokine storm group, all with acute necrotizing encephalopathy (ANE); 9 cases in the excitotoxicity group, 8 cases with acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) and 1 case with hemiconvulsion-hemiplegia syndrome; and 10 cases of unclassified encephalopathy. Laboratory studies revealed elevated glutathione transaminase in 9 cases, elevated glutamic alanine transaminase in 4 cases, elevated blood glucose in 3 cases, and elevated D-dimer in 3 cases. Serum ferritin was elevated in 3 of 5 cases, serum and cerebrospinal fluid (CSF) neurofilament light chain protein was elevated in 5 of 9 cases, serum cytokines were elevated in 7 of 18 cases, and CSF cytokines were elevated in 7 of 8 cases. Cranial imaging abnormalities were noted in 18 cases, including bilateral symmetric lesions in 3 ANE cases and "bright tree appearance" in 8 AESD cases. All 22 cases received symptomatic treatment and immunotherapy (intravenous immunoglobulin or glucocorticosteroids), and 1 ANE patient received tocilizumab. The follow-up time was 50 (43, 53) d, and 10 patients had a good prognosis and 12 patients had a poor prognosis. No statistically significant differences were found between the two groups in terms of epidemiology, clinical manifestations, biochemical indices, and duration of illness to initiate immunotherapy (all P>0.05). Conclusions: SARS-CoV-2 infection is also a major cause of AE. AESD and ANE are the common AE syndromes. Therefore, it is crucial to identify AE patients with fever, convulsions, and impaired consciousness, and apply aggressive therapy as early as possible.

This study was aimed to understand the current status of the antimicrobial resistance and molecular distribution of Campylobacter in various poultry in Jiaodong area,to provide a basis for effective prevention and control of the Campy-lobacter risk to poultry products and human health.Campylobacter was isolated and identified from 565 cloacal samples collect-ed in the Jiaodong area from August to October 2021 through conventional bacterial isolation and culture,mass spectrometry,microbroth dilution and multilocus sequence typing(MLST).The drug resistance and molecular typing of 131 representative strains(67 Campylobacter jejuni and 64 Campylobacter coli)were studied separately.Antimicrobial resistance analysis indica-ted that 131 isolates were highly resistant to ciprofloxacin,nalixic acid and tetracycline,with resistance rates of 96.21％,96.21％and 95.45％,respectively.Except for 2 strains,62 strains of C.coli were completely resistant to these three drugs(100％).A total of 65 strains of 131 strains were multidrug re-sistant,and the overall multidrug resistance rate was 49.62％,among which 11 strains(16.42％)of C.jejuni were resistance to 3-5 antibiotics,and 54 strains(84.38％)of C.coli were re-sistance to 3-6 antibiotics.Among the isolates from different poultry sources,waterfowl isolates were the most resistant,fol-lowed by broiler isolates.The MLST typing results revealed 72 alleles and 35 sequence types obtained from 67 strains of C.je-juni,and the distribution was relatively dispersed,without a dominant ST type and homologous complex.A total of 27 alleles and 19 sequence types were obtained from 64 strains of C.coli.Moreover,59.38％(38/64)strains were homologous complex CC-828,in which the ST-1586 sequence type was most frequent,followed by ST-825.ST-1586,ST-9944 and ST-3735 were the main sources of C.coli in broilers,and ST-825 and ST-1586 were the main sources of C.coli in waterfowl.Differences in C.jejuni and C.coli carriage were observed among poultry in the Jiaodong area.Carriage of the two bacteria was more common in laying hens than in broilers and waterfowl.C.jejuni from poultry in the Jiaodong area was highly resistant to ciprofloxacin,nalixic acid and tetracycline,but had good sensitivity to other drugs.C.coli was highly resistant to a variety of antibiotics,and multiple drug resistance was common.St-type dispersal of C.jejuni showed high genetic diversity.C.coli was cloned and transmitted mainly by ST-1586 in broiler chickens and waterfowl.Poultry carry C.jejuni,which can cause serious diseases in humans.Therefore,dynamic monitoring of Campylobacter from poultry should be strengthened.

Ferroptosis is a novel cell death mode proposed in recent years, which is characterized by intracellular iron-dependent lipid peroxidation. Its mechanisms include lipid peroxidation, iron accumulation and the imbalance of antioxidant system. The crosstalk between ferroptosis and asthma is gradually deepening. Elucidating the specific mechanism of ferroptosis in regulating asthma is helpful to broaden the understanding of the pathology of asthma. This paper expounds the role of ferroptosis in airway epithelial cells in the occurrence and development of asthma from three perspectives: lipid peroxidation, iron accumulation and the imbalance of antioxidant system, hoping to find new targets and strategies for asthma treatment.

OBJECTIVE: To compare the clinical effect of SUN 's abdominal acupuncture and conventional acupuncture in the treatment of depression after methamphetamine withdrawal. METHODS: A total of 80 female patients with depression after methamphetamine withdrawal were randomly divided into an observation group (40 cases, 1 case dropped off) and a control group (40 cases, 2 cases dropped off). The control group was treated with conventional acupuncture at Baihui (GV 20), Yintang (GV 29), Taichong (LR 3), Shenmen (HT 7), Neiguan (PC 6), Danzhong (GV 17), and the observation group was treated with SUN 's abdominal acupuncture at area 1 of the abdomen and area 8 of the abdomen. Both groups were treated once a day, 30 min each time, 6 days as a course of treatment, 1 day rest between treatment courses, a total of 4 courses of treatment. The scores of withdrawal symptoms, Hamilton depression scale (HAMD), Pittsburgh sleep quality index (PSQI) scale and serum serotonin (5-HT) level were compared between the two groups before and after treatment. RESULTS: After treatment, the scores of withdrawal symptoms, HAMD and the various scores and total score of PSQI scale in the two groups were all lower than before treatment (P<0.01), and the scores of withdrawal symptoms, HAMD and the sleep quality, time to fall asleep, sleep time scores and total score of PSQI in the observation group were lower than the control group (P<0.05, P<0.01). After treatment, the serum 5-HT level of the two groups was increased (P<0.01), and that in the observation group was higher than the control group (P<0.05). CONCLUSION SUN 's abdominal acupuncture can improve withdrawal symptom, depression and sleep quality, increase serum 5-HT content in treatment of depression after methamphetamine withdrawal, and has better effect than conventional acupuncture.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective: This study aims to survey the incidence of surgical site infection (SSI) in China and to analyze its risk factors, so as to prevent and control SSI after colorectal surgery. Methods: An observative study was conducted. Based on a program of Chinese SSI Surveillance from 2018 to 2020, the clinical data of all adult patients undergoing colorectal surgery during this time period were extracted. These included demographic characteristics and perioperative clinical parameters. Minors, pregnant women, obstetric or gynecological surgery, urological system surgery, retroperitoneal surgery, resection of superficial soft tissue masses, and mesh or other implants were excluded. A total of 2122 patients undergoing colorectal surgery from 50 hospitals were included, including 1252 males and 870 females. The median age was 63 (16) years and the median BMI was 23 (4.58) kg/m². The primary outcome was the incidence of SSI within 30 days after colorectal surgery. The secondary outcomes were mortality within 30 days postoperatively, length of ICU stays and postoperative hospital stays, and cost of hospitalization. Patients were divided into the SSI group and non-SSI group based on the occurrence of SSI. Multivariable logistic regression was performed to analyze risk factors of SSI after colorectal surgery, and subgroup analysis was conducted for open and laparoscopic surgery. Results: The incidence of SSI after colorectal surgery was 5.6% (119/2122), including 47 cases (47/119, 39.5%) with superficial incisional infections, 24 cases (24/119, 20.2%) with deep incisional infections, and 48 cases (48/119, 40.3%) with organ/space infections. The occurrence of SSI significantly increased mortality [2.5% (3/119) vs. 0.1%(3/2003), χ²=22.400, P=0.003], the length of ICU stay [0 (1) day vs. 0(0) day, U=131 339, P<0.001], postoperative hospital stay [18.5 (12.8) days vs. 9.0 (6.0) days, U=167 902, P<0.001], and medical expenses [75 000 (49 000) yuan vs. 60 000 (31 000) yuan, U=126 189, P<0.001] (P<0.05). Multivariate analysis revealed that hypertension (OR=1.782, 95%CI: 1.173-2.709, P=0.007), preoperative albumin level (OR=1.680, 95%CI: 1.089-2.592, P=0.019), a contaminated or infected incision (OR= 1.993, 95%CI: 1.076-3.689, P=0.028), emergency surgery (OR=2.067, 95%CI: 1.076-3.972, P=0.029), open surgery (OR=2.132, 95%CI: 1.396-3.255, P<0.001), and surgical duration (OR=1.804, 95%CI: 1.188-2.740, P=0.006) were risk factors for SSI, while preoperative skin preparation (OR=0.478, 95%CI: 0.310-0.737, P=0.001) was a protective factor for SSI. Subgroup analysis was performed on patients undergoing open or laparoscopic surgery. The incidence of SSI in the open surgery group was 10.2%, which was significantly higher than that in the laparoscopic or robotic group (3.5%, χ²=39.816, P<0.001). Subgroup analysis identified that a contaminated or infected incision (OR=2.168, 95%CI: 1.042-4.510, P=0.038) and surgical duration (OR=2.072, 95%CI: 1.171-3.664, P=0.012) were risk factors for SSI after open surgery, while mechanical bowel preparation (OR=0.428, 95%CI: 0.227-0.807, P=0.009) and preoperative skin preparation (OR=0.356, 95%CI: 0.199-0.634, P<0.001) were protective factors for SSI after open surgery. In laparoscopic surgery, diabetes mellitus (OR= 2.292, 95%CI: 1.138-4.617, P=0.020) and hypertension (OR=2.265, 95%CI: 1.234-4.159, P=0.008) were risk factors for SSI. Conclusions: The incidence of SSI after colorectal surgery is 5.6%. Minimally invasive surgery should be selected to reduce the occurrence of postoperative SSI. To prevent the occurrence of SSI after open surgery, skin preparation and mechanical bowel preparation should be performed before the operation, and the duration of the operation should be shortened as much as possible. In the perioperative period, care of patients with hypertension, diabetes, and contaminated or infected incisions should be given particular attention.

Objective: To understand the associations between internet addiction, screen time (computer/mobile devices use and television watching time) and depressive symptoms in adults. Methods: A total of 6 932 adults aged <60 years from the Tianjin Chronic Low-grade Sgstemic Inflammation and Health (TCLSIH) Cohort of 2013-2019 were surveyed. The information about their computer/mobile devices use and television watching time were collected by using a self-reported questionnaire. The depressive symptoms were assessed using the self-rating depression scale (SDS). The adults surveyed were divided into two groups: non-depressive symptom group (SDS score <45) and depressive symptom group (SDS score ≥45). The associations between internet addiction, screen time and depressive symptoms were estimated using Cox proportional hazard regression models, with adjusting for multiple confounders. Results: After adjusting for confounding factors, the hazard ratios (HRs) of depressive symptom in the adults who had internet addiction before, had light internet addiction and had moderate or severe internet addiction were 0.83 (95%CI: 0.56-1.23) , 1.20 (95%CI: 1.03-1.41) for light and 1.48 (95%CI: 1.16-1.89), respectively, compared with those without internet addiction. The linear trend test results of the association between internet addiction and depressive symptoms was significant (trend P<0.001). Compared with the adults who used computer/mobile devices for <1 hour/day, the HRs of depressive symptoms in those who used computer/mobile devices for >1 hour, >3 hours, >5 hours and >10 hours were 0.59 (95%CI: 0.40-0.88), 0.58 (95%CI: 0.40-0.85), 0.52 (95%CI: 0.36-0.76) and 0.69 (95%CI: 0.45-1.05) respectively, a U-shaped association was found between computer/mobile devices use time and depressive symptoms (trend P<0.001). Compared with the adults who never watch TV, the HR of depressive symptoms was 1.36 (95%CI:1.09-1.69) for those watching TV for ≥3 hours/day in crude model and 1.34 (95%CI: 1.07-1.68) for those watching TV for ≥3 hours/day in adjusted model (trend P<0.001). Conclusion: Our findings suggested that internet addiction and television watching time were associated with an increased risk of depressive symptoms, while computer/mobile device use time was associated with a reduced risk of depressive symptoms.

OBJECTIVES: The present study aimed to explore the innervation of the anterior hard palatine and its relationship with individual development stage. Specifically, the effects of anesthesia on patients of different ages were observed, and neurodevelopment in the maxillofacial region was invesitgated. References that are helpful in selecting local anesthesia were provided. METHODS: A total of 182 patients with mixed dentition were randomly divided into the nasopalatine nerve block and greater palatine nerve block groups. Then, 219 patients with permanent dentition were divided into an adolescent group (13-18 years old) and adult group (over 19 years old), all of whom underwent bilateral greater palatine nerve block. Palatal mucosal pain sensation was tested pre- and post-anesthesia with Von Frey hairs. RESULTS: Among the children with mixed dentition, bilateral greater palatine nerve block tended to result in better anesthetic effects than nasopalatine nerve block ( CONCLUSIONS The sensation of the anterior hard palatine seems mainly dominated by the greater palatine nerve until mixed dentition and gradually shifted to the nasopalatine nerve in conjunction with maxillary development and tooth replacement. Hence, the innervation of the anterior hard palatine induce a secondary development during the development of the maxilla.
