Objective: To analyze the adverse treatment outcome status and spatio temporal characteristics of pulmonary tuberculosis cases among students in Qinghai Province, providing a reference basis for pulmonary tuberculosis prevention and control in schools. Methods: The data of student pulmonary tuberculosis cases during 2013-2023 in Qinghai Province were obtained through the "National Tuberculosis Management Information System", and the treatment outcome was retrospectively analyzed. The Joinpoint model was applied to analyze the adverse outcome rate trend. Global and local spatial autocorrelation analysis, and spatiotemporal scan cluster analysis were conducted on the adverse outcome rate of pulmonary tuberculosis among students in Qinghai Province. Results: During 2013-2023, 488 cases of adverse outcomes were reported among 6 155 students with pulmonary tuberculosis in Qinghai Province, with an adverse outcome rate of 7.93%. The reporting adverse outcome rate of pulmonary tuberculosis among students showed a downward trend from 2013 to 2023 (APC=-16.20, t =-3.89, P <0.05). The results of spatial autocorrelation showed that the adverse outcome rate of pulmonary tuberculosis was Moran s I >0 among students in Qinghai Province. Among them, there was a spatially positive correlation in the adverse outcome rate of pulmonary tuberculosis among students in 2020, 2021 and 2022(all Z >1.96, all P <0.05). The results of clustering and outlier analysis in local spatial autocorrelation showed that the areas with high high aggregation were mainly concentrated in Yushu Prefecture(Zhiduo County, Zaduo County, Nangqian County, Yushu City), Huangnan Prefecture (Zeku County, Henan County) and Hainan Prefecture (Tongde County). The low low concentration areas were distributed in Haidong City, Xining City, Haibei Prefecture (Gangcha County, Qilian County), Haixi Prefecture (Tianjun County, Ulan County), Hainan Prefecture (Gonghe County, Guide County) and Huangnan Prefecture (Tongren City, Jianzha County). The spatio temporal scanning showed that a total of two possible aggregation areas had been detected. Among them, the first level aggregation area composed of 10 counties and districts in Yushu Prefecture and Guoluo Prefecture of Qinghai Province, and the cluster radius was 658.09 km, the RR was 10.58 , and the LLR was 305.91; the second level aggregation area was composed of 16 counties and districts in Hainan Prefecture, Haixi Prefecture, Huangnan Prefecture and Guoluo Prefecture, and the cluster radius was 407.02 km, the RR was 9.83, and the LLR was 152.48 (both P <0.05). Conclusions The reporting rates of adverse treatment outcome of pulmonary tuberculosis cases among students in Qinghai Province remain relatively high and unevenly distribute throughout the province. Supervision should be strengthened to improve cases compliance,and to reduce student pulmonary tuberculosis adverse treatment outcomes incidence.

Objective: To investigate the prevalence of hepatitis B and hepatitis C in Hotan Prefecture, Xinjiang Uygur Autonomous Region, so as to provide insights into prevention and intervention strategies for viral hepatitis for these populations. Methods: Data on hepatitis B and hepatitis C cases in Hotan Prefecture from 2016 to 2022 were collected through the Chinese Disease Prevention and Control Information System. The temporal, demographic and regional distribution characteristics of hepatitis B and hepatitis C incidence were analyzed using the descriptively epidemiological method. The trends in the incidence of hepatitis B and hepatitis C from 2016 to 2022 were analyzed using average annual percent change (AAPC). Results: A total of 8 910 hepatitis B cases and 4 106 hepatitis C cases were reported in Hotan Prefecture from 2016 to 2022, with average annual incidences of 55.60/105 and 25.61/105, respectively. The average annual incidence of hepatitis B in males was 66.78/105, which was higher than that in females (43.83/105, P<0.05). The average annual incidence of hepatitis C in males was 25.70/105, while in females it was 25.36/105, with no statistically significant difference (P>0.05). With increasing age, the incidence of hepatitis B showed an "M"-shaped trend, with the highest average annual incidence in the age group of 20-<30 years (97.20/105); the incidence of hepatitis C first increased and then decreased, with the highest average annual incidence in the age group of 70-<80 years (102.50/105). The majority of the cases were farmers/migrant workers, with 5 610 (62.96%) and 2 963 cases (72.16%), respectively. The top three counties with higher average annual incidences of hepatitis B were Minfeng County (84.78/105), Karakax County (81.69/105) and Lop County (72.20/105), and the top three counties with higher average annual incidences of hepatitis C were Pishan County (46.92/105), Karakax County (35.62/105) and Hotan County (26.31/105). The incidences of hepatitis B and hepatitis C in Hotan Prefecture showed downward trends from 2016 to 2022 (AAPC=-10.711% and -16.594%, both P<0.05), with consistent trends observed in Hotan City, Hotan County, Pishan County and Qira County (all P<0.05). Conclusions From 2016 to 2022, the incidences of hepatitis B and hepatitis C in Hotan Prefecture both showed downward trends. Young and middle-aged adults, males, and farmers/migrant workers were the high-risk populations for hepatitis B, while middle-aged and elderly adults and farmers/migrant workers were the high-risk populations for hepatitis C.

Daochisan is a pediatric famous classical formula in traditional Chinese medicine（TCM） specializing in clearing the heart， disinhibiting water and enriching Yin， which has been inherited and developed by medical experts of successive generations. The formula can be traced back to Xiaoer Yaozheng Zhijue written by QIAN Yi from Song dynasty， and most of the later-developed Daochisan（Daochitang） is based on this formula with additions and subtractions. So as to promote the literature excavation of this formula， this paper conducts a thorough textual research and analysis of the composition， processing， preparation methods， clinical applications of Daochisan based on a systematic collation of relevant ancient and modern literature in the method of bibliometrics. A total of 127 pieces of data involving 86 antient TCM books were collected. Statistical analysis showed that the drug origin of Daochisan is basically clear， we suggest that Rehmanniae Radix is the root tuber of Rehmannia glutinosa of Scrophulariaceae， Akebiae Caulis is the dry stem of Akebia quinata of Lardizabalaceae， Glycyrrhizae Radix et Rhizoma is the dry root and stem of Glycyrrhiza uralensis of legume， bamboo leaf is the dry leaves of Phyllostachys nigra var. henonis of gramineous plants. Four herbs are recommended to use its raw products. The key information of the dosage and decocting method is supposed to be "4.13 g each of raw Rehmanniae Radix， raw Glycyrrhizae Radix et Rhizoma， Akebiae Caulis， adding 300 mL of water， and then adding 4.13 g of bamboo leaf， decocting together to 150 mL， taking warmly after meal". Daochisan has the effect of clearing the heart and enriching Yin， disinhibiting water and relieving stranguria， and is widely used in treating symptoms such as heart vexed hotness， hydrodipsia and reddish complexion. Modern studies have showed that Daochisan are frequently used in treating oral ulcer， herpetic stomatitis， urinary tract infection， herpes zoster and other diseases. The above research results can provide scientific reference for the future development and research of Daochisan.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

Objective:To investigate the predictive value of fluid-attenuated inversion recovery (FLAIR) signal strength ratio (SIR) in onset time≤4.5 h in patients with acute ischemic stroke.Methods:A retrospective analysis was performed; 180 acute ischemic stroke patients admitted to Department of Neurology, Nanjing Hospital Affiliated to Nanjing Medical University from January 2020 to June 2023 were chosen. Hypoperfusion intensity ratio (HIR) was used to evaluate the collateral circulation (poor collateral circulation: HIR≤0.4; good collateral circulation: HIR>0.4); clinical data and imaging indexes between poor collateral circulation and good collateral circulation groups were compared. Univariate and multivariate Logistic regressions were used to analyze the influencing factors for onset time≤4.5 h in patients with acute ischemic stroke. Correlation between SIR and onset time was analyzed in patients with acute ischemic stroke. Role of HIR as agency between SIR and onset time was explored. Receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of SIR and diffusion weighted imaging (DWI)-FLAIR mismatch in onset time≤4.5 h in acute ischemic stroke patients.Results:Of the 180 patients, 100 were into the good collateral circulation group and 80 were into the poor collateral circulation group; compared with the good collateral circulation group, the poor collateral circulation group had significantly higher percentage of patients with hyperlipidemia, larger DWI infarction volume before treatment, larger perfusion weighted imaging (PWI)-DWI mismatch volume and higher SIR ( P<0.05). In these 180 patients, 76 had onset time≤4.5 h and 104 had onset time>4.5 h. Univariate Logistic regression analysis showed that hyperlipidemia, DWI infarct volume before treatment, DWI-FLAIR mismatch, HIR and SIR were influencing factors for onset time≤4.5 h in acute ischemic stroke patients ( P<0.05). Multivariate Logistic regression analysis showed that hyperlipidemia ( OR=6.654, 95% CI: 5.751-8.824, P<0.001), HIR ( OR=0.724, 95% CI: 0.521-1.321, P=0.041) and SIR ( OR=739.881, 95% CI: 383.296-14 258.065, P<0.001) were independent influencing factors for onset time≤4.5 h in acute ischemic stroke patients. Pearson correlation analysis showed that SIR was positively correlated to onset time in patients with acute ischemic stroke ( r=0.420, P<0.05), and SIR was positively correlated to onset time in patients from poor collateral circulation group ( r=0.781, P<0.05). ROC curve showed that AUC of SIR in predicting onset time≤4.5 h was 0.917 (95% CI: 0.814-1.000, P<0.001) and that of DWI-FLAIR mismatch in predicting onset time≤4.5 h was 0.530 (95% CI: 0.509-0.757, P=0.075) in poor collateral circulation group, enjoying significant difference in predictive efficacy. Conclusion:Acute ischemic stroke patients with low HIR and SIR have higher odds of onset time≤4.5 h; SIR can more accurately predict the onset time in these patients with poor collateral circulation.

This paper discussed the historic evolution of Juanbitang and similar decoctions， clarified the historic development of Yangshi Juanbitang and Chengshi Juanbitang， and probed into the key information of the meaning， original plants， processing methods， and modern dosage and usage of Chengshi Juanbitang. A total of 267 pieces of relevant information were collected from ancient traditional Chinese medicine （TCM） books， among which 53 pieces of effective data were included in this study. The results showed that both Chenshi Juanbitang and Yangshi Juanbitang were originated from Duhuo Jishengtang recoded in the Important Prescriptions Worth a Thousand Gold for Emergency （Bei Ji Qian Jin Yao Fang）. According to the standard of "1 qian roughly equals 3.73 g" in the measurement system of the Qing Dynasty， we suggest Chenshi Juanbitang is composed of 3.73 g Notopterygii Rhizoma et Radix， 3.73 g Angelicae Pubescentis Radix， 3.73 g Gentianae Macrophyllae Radix， 11.19 g Angelicae Sinensis Radix， 11.19 g Mori Ramulus， 2.61 g Chuanxiong Rhizoma， 1.87 g Cinnamomi Cortex， 1.87 g stir-fried Glycyrrhizae Radix et Rhizoma， 7.46 g Piperis Kadsurae Caulis， 2.98 g Olibanum， and 2.98 g Aucklandiae Radix， which should be decocted with 600 mL water to reach a volume of 300 mL. The decoction should be taken 3 times a day before meals. Juanbitang， a classical formula specialized for treating impediment diseases， has the effects of dispelling wind， removing dryness， and alleviating impediment to relieve pain. It can be used for treating vexing pain in body， spasm of nape and back， and heaviness in waists and legs. Modern studies have shown that Juanbitang can be used for treating rheumatoid arthritis， knee osteoarthritis， and periarthritis of shoulder. The above results served as a reference for the future development of Juanbitang.

Objective:To translate the University of Rhode Island Change Assessment of voice scale（URICA-Voice） into Chinese and test its reliability and validity. Methods:The URICA-Voice scale was converted into Chinese by literal translation, cultural adjustment, expert consultation, pre-investigation, and back translation. Convenience sampling was used to recruit patients at four speech therapy centers from February to May 2022. Then the Chinese version of the scale was distributed to them, and the reliability and validity of the scale were tested after data collection. Cronbach ɑ was used to evaluate the reliability. The critical ratio method and Pearson correlation coefficient were used for item analysis. Item-level content validity, scale-level content validity, and confirmatory factor analysis were used to test the validity of the scale. Results:A total of 247 valid questionnaires were collected. ①Item analysis: the critical ratios between a high-score and low-score groups of 32 items were all statistically significant（P<0.01） and all the critical ratios were above 3.00. The Pearson correlation between 32 items and the total score was significant（P<0.01）. ②Validity analysis: I-CVI=1.00, S-CVI/Ave=1.00, χ²/df=2.30, RMSEA=0.07. Except for item 9 and 23, the standardized factor loading coefficients of other items were all above 0.50. AVE of the four dimensions of the scale was all above 0.50, and the combined reliability of the four dimensions was all above 0.70. The correlation coefficients between dimensions were less than the square root of the AVE of the dimension itself. ③Reliability analysis: the Cronbach ɑ of the whole scale was 0.94, and the Cronbach ɑ of the four dimensions were 0.88, 0.92, 0.94, and 0.88 respectively. Conclusion:The Chinese version of URICA-Voice has good reliability and validity, and can be used as a specific measurement tool for evaluating the compliance of voice training in China.

Remarkable improvement relative to traditional approaches in the treatment of hematological malignancies by chimeric antigen receptor (CAR) T-cell therapy has promoted sequential approvals of eight commercial CAR T products within last 5 years. Although CAR T cells' productization is now rapidly boosting their extensive clinical application in real-world patients, the limitation of their clinical efficacy and related toxicities inspire further optimization of CAR structure and substantial development of innovative trials in various scenarios. Herein, we first summarized the current status and major progress in CAR T therapy for hematological malignancies, then described crucial factors which possibly compromise the clinical efficacies of CAR T cells, such as CAR T cell exhaustion and loss of antigen, and finally, we discussed the potential optimization strategies to tackle the challenges in the field of CAR T therapy.

Objective:To compare the maternal and fetal outcomes of women with cervical insufficiency (CI) undergoing McDonald cerclage (MC) and laparoscopic cervicoisthmic cerclage (LCC), so as to provide evidence for the selection of cerclage methods.Methods:A retrospective trial was carried out in the First Affiliated Hospital of Sun Yat-sen University from January 2010 to December 2020. A total of 221 women who underwent the prophylactic cerclage were divided into MC group ( n=54), LCC with MC history group ( n=28) and LCC without MC history group ( n=129) by the mode of operation and whether the pregnant women who underwent LCC had MC history. General clinical data, pregnancy complications and pregnancy outcomes were compared between the three groups. Results:(1) General clinical data: the proportion of women accepted cervical cerclage during pregnancy in MC group, LCC with MC history group and LCC without MC history group were 100.0% (54/54), 7.1% (2/28) and 27.1% (35/129), respectively ( P<0.001). The indications of the three groups showed statistical significance ( P=0.003), and the main indication was the history of abortion in the second and third trimester [75.9% (41/54) vs 89.3% (25/28) vs 84.5% (109/129)]. (2) Pregnancy complications: the incidence of abnormal fetal position [7.8% (4/51) vs 17.4% (4/23) vs 19.8% (24/121)], placenta accrete [5.9% (3/51) vs 13.0% (3/23) vs 11.6% (14/121)], uterine rupture [0 vs 4.3% (1/23) vs 5.8% (7/121)] in the MC group were all lower than those in LCC with MC history and LCC without MC history groups. However, there were no statistical significances (all P>0.05). Intrauterine inflammation or chorioamnionitis [15.7% (8/51) vs 0 vs 0.8% (1/121)] and premature rupture of membrane [23.5% (12/51) vs 4.3% (1/23) vs 0] were both significantly higher in MC group than those in LCC with MC history and LCC without MC history groups (all P<0.001). (3) Pregnancy outcomes: the cesarean section rate was significantly lower in MC group (41.2%, 21/51) than that in LCC with MC history group (100.0%, 23/23) and LCC without MC history group (100.0%, 121/121; P<0.001). MC group was associated with lower expenditure than LCC with MC history and LCC without MC history groups (12 169 vs 26 438 vs 27 783 yuan, P<0.001). The success rates of live birth cerclage did not differ significantly in MC (94.4%, 51/54), LCC with MC history (82.1%, 23/28) and LCC without MC history (93.8%, 121/129) groups ( χ2=5.649, P=0.059). There was no significant difference in neonatal intensive care unit occupancy, neonatal birth weight and neonatal asphyxia between the three groups (all P>0.05). Conclusions:Both LCC and MC are the treatment choice for women with CI, which may get similar liver birth. However, MC has the advantages of low cesarean section rate, economical and easy operation. Therefore, MC is recommended as the first choice for CI patients, and LCC is for women with failed MC.

Objective:To investigate the feasibility, effectiveness and safety of indocyanine green (ICG) navigation in the surgical resection of abdominal wall endometriosis (AWE).Methods:Seven women undergoing surgery for AWE in First Affiliated Hospital of Sun Yat-sen University (from July 1, 2021 to October 1, 2021) were collected. After exposure of the focus, ICG were used intravenously (0.25 mg/kg) as fluorescent dye for the intraoperative evaluation of AWE vascularization. Resection of the AWE was guided by direct visualization of the focus under standard laparoscopy with a near-infrared (NIR) camera head. Surgical margin around the AWE (3, 6, 9 and 12 point) and the margin under the focus were obtained for postoperative pathological examination of endometriosis. Time from injection to fluorescence visualization, the proportion of fluorescence visualization, time of fully resection of AWE, side effects related to the use of ICG, perioperative complications as well as the pathological result of the surgical margins were recorded.Results:ICG fluorescence of the AWE were seen in 5 patients (5/7). The mean time from injection to fluorescence visualization was (46.7±9.8) s. The mean time of fully resection of AWE was (16.4±7.0) minutes. There were no side effects related to the use of ICG. The rate of class-A wound healing was 7/7. All of the surgical margins were confirmed endometriosis-negative by postoperative pathological examination.Conclusion:ICG fluorescence visualization could conduct accurate resection of AWE, which is clinically safe and effective.
