Objective China is among the 30 countries with a high burden of tuberculosis(TB)worldwide,and TB remains a public health concern.Kashgar Prefecture in the southern Xinjiang Autonomous Region is considered as one of the highest TB burden regions in China.However,molecular epidemiological studies of Kashgar are lacking. Methods A population-based retrospective study was conducted using whole-genome sequencing(WGS)to determine the characteristics of drug resistance and the transmission patterns. Results A total of 1,668 isolates collected in 2020 were classified into lineages 2(46.0%),3(27.5%),and 4(26.5%).The drug resistance rates revealed by WGS showed that the top three drugs in terms of the resistance rate were isoniazid(7.4%,124/1,668),streptomycin(6.0%,100/1,668),and rifampicin(3.3%,55/1,668).The rate of rifampicin resistance was 1.8%(23/1,290)in the new cases and 9.4%(32/340)in the previously treated cases.Known resistance mutations were detected more frequently in lineage 2 strains than in lineage 3 or 4 strains,respectively:18.6%vs.8.7 or 9%,P<0.001.The estimated proportion of recent transmissions was 25.9%(432/1,668).Multivariate logistic analyses indicated that sex,age,occupation,lineage,and drug resistance were the risk factors for recent transmission.Despite the low rate of drug resistance,drug-resistant strains had a higher risk of recent transmission than the susceptible strains(adjusted odds ratio,1.414;95%CI,1.023-1.954;P = 0.036).Among all patients with drug-resistant tuberculosis(DR-TB),78.4%(171/218)were attributed to the transmission of DR-TB strains. Conclusion Our results suggest that drug-resistant strains are more transmissible than susceptible strains and that transmission is the major driving force of the current DR-TB epidemic in Kashgar.

This paper summarized the clinical experience of Professor HE Chengyao in treating recurrent miscarriage complicated with subclinical hypothyroidism. It is believed that kidney yang insufficiency is the root of the disease， while the functional decline of the five zang （脏） organs and the obstruction of the sanjiao （三焦） pivot are the key links of the pathogenesis. In clinical practice， the division of yang numbers in the Book of Changes （《周易》） is followed， and 9 months is advocated as the basic treatment cycle for recurrent miscarriage complicated with subclinical hypothyroidism. During the first half of the period before pregnancy （the first 3 months）， it is recommended to warm the pivot and sanjiao （三焦）， and Yougui Pills （右归丸） is commonly used as the basic prescription to warm and supplement the kidney yang， together with the medicinals of invigorating blood and dissolving stasis， regulating and unblocking qi movement. During the second half of the period before pregnancy （the second 3 months）， it is better to nourish essence and nature the embryo commonly with Wuzi Yanzong Pills （五子衍宗丸） in modification. After pregnancy （the third 3 months）， it is suggested to supplement kidney and consolidate chong mai （冲）， replenish qi and nourish blood mainly， supplemented by warming and nourishing heart yang， and self-made Bushen Antai Formula （补肾安胎方） which is modified based on the combination of Shoutai Pills （寿胎丸） and Wenbao Beverage （温胞饮） is commonly used.Additionally， it is recommended to adjust lifestyle and diet so as to balance yin and yang and improve the physical condition.

Objective:To investigate the effect of quality improvement (QI) project on delayed cord clamping (DCC) implementation in very preterm infants.Methods:This study retrospectively collected the clinical data and assessed the QI indices of very preterm infants born in the Women and Children's Hospital of Chongqing Medical University and transferred to the Neonatology Department from January 2017 to January 2021. The indices for QI assessment included three types: (1) process indices: the implementation rate and timing of DCC; (2) outcome indices: hemoglobin level and hematocrit, etc; (3) balancing indices: the proportion of neonates requiring endotracheal intubation in the delivery room and chest compressions, Apgar score body temperature, and blood pH value on admission, etc. There were four phases for the implementation of QI, the pre-QI period (January to December of 2017), the QI period (January to December of 2018), the post-QI period (January to December of 2019), and the sustained-QI period (January 2020 to January 2021). The QI project was performed since August 2018. Control charts or statistical tests were used for statistical analysis.Results:(1) Process indices: After the implementation of the QI project, the practice of DCC increased from 0 to 82.2%, and the timing of umbilical cord clamping was from 0 s to a delay of 47.1 s. (2) Outcome indices: The levels of hemoglobin in the QI period, the post-QI period, and the sustained-QI period were significantly higher than those in the pre-QI period [(202.22±28.84), (210.10±33.52), (210.52±32.27) g/L vs. (187.94±35.29) g/L; F=8.61, P<0.001]. The hematocrit values in the post-QI period and the sustained-QI period were significantly higher than those in the pre-QI period [(58.99±8.71) %, (60.18±8.06)% vs. (55.41±9.17)%; χ2=5.13, P=0.002]. The other indices showed no statistical differences in different phases. (3) Balancing indices: The proportions of neonates receiving endotracheal intubation in the delivery room in the post-QI period and the sustained-QI period were significantly lower than those in the pre-QI period [16.0% (19/119), 13.2% (25/191) vs. 42.3% (30/71); χ2=29.08, P<0.001]. The body temperature on admission increased gradually through the four periods [pre-QI period: 35.3 ℃ (34.5-36.1 ℃); QI period: 36.0 ℃ (34.0-37.7 ℃); post-QI period: 36.0 ℃ (35.6-37.4 ℃); sustained-QI period: 37.0 ℃ (35.9-38.1 ℃); H=277.88, P<0.001]. The blood pH value on admission in the sustained-QI period [7.32 (6.85-7.50)] was significantly higher than those in the other three periods [7.26 (7.07-7.46), 7.26 (7.04-7.43), and 7.25 (6.91-7.49); H=34.46, P<0.001]. Conclusion:The interventions in this QI project significantly increase the practice of DCC and enable a longer DCC in very preterm infants.

【Objective 】 To explore the influencing factors of Yang deficiency constitution in traditional Chinese medicine (TCM) from the perspective of mathematics with the use of calculation formulas, so as to protect patients from getting diseases caused by Yang deficiency constitution and provide suggestions for TCM disease prevention. 【Methods】  Based on the classification and determination criteria of TCM constitution implemented by China Association of Chinese Medicine, data for 24 solar terms from May 5, 2020(Start of Summer) to April 20, 2021 (Grain Rain) for the identification of Yang deficiency were collected by mobile constitution identification system. The grey correlation analysis method was used to determine the grey correlation degree of the factors influencing Yang deficiency constitution. In addition, a random forest model was constructed for the verification of the results from the grey correlation analysis, and for the evaluation of correlation degree between Yang deficiency constitution and its influencing factors. 【Results】  A total of 16 259 sets of data were collected from healthy or sub-healthy individuals aged from 18 to 60 years living in the central and northeastern parts of Sichuan Province(China) for the identification of TCM constitutions. After screening and preprocessing, a total of 544 sets of data for the identification of Yang deficiency constitution, involving 18 aspects of factors influencing Yang deficiency constitution. The results of the grey correlation analysis showed that there were 12 influencing factors whose grey correlation degree with Yang deficiency constitution was greater than 0.6. The accuracy of these 12 influencing factors with the training set and validation set of the Yang deficiency constitution random forest model were 98.39% and 93.12%, respectively. 【Conclusion】  In the sample data selected in this paper, grey correlation analysis is the appropriate technology to analyze the influencing factors of Yang deficiency constitution. It provides a new idea and a new methodological reference for the research and analysis of the influencing factors of TCM constitution.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Objective:To explore the clinical therapeutic effect and follow-up prognosis of preterm infants with neonatal respiratory distress syndrome (NRDS) managed by less invasive surfactant administration (LISA) and traditional intubation-surfactant-extubation (INSURE) of pulmonary surfactant (PS).Methods:Data during hospitalization and follow-up period of 187 NRDS preterm infants (gestational age 24 weeks to 31 + 6 weeks, and birth weight <1 500 g) admitted to the Department of Neonatology, the Women and Children′s Hospital of Chongqing Medical University from March 2019 to February 2021 were retrospectively analyzed.NRDS preterm infants who were injected with PS by LISA were included in the LISA group (144 cases), and those who were injected with PS by INSURE were included in the INSURE group (43 cases). The propensity score matching method was used to correct the confounding factors between groups, and the covariate equilibrium samples between groups were obtained (39 cases in each group). Clinical treatment effect and prognosis of physical development, hearing and vision development, nervous system development, respiratory system diseases and other conditions of the two groups of children were compared using the t test, Chi- square test and other statistical analysis methods as appropriate. Results:(1)Compared with that of the INSURE group, the incidence of BPD [12 cases (33.3%) vs.23 cases (63.9%), χ2=6.727, P=0.009] and ROP [13 cases (36.1%) vs.26 cases (72.2%), χ2=9.455, P=0.002] in the LISA group were significantly lower.The incidence of mild BPD [8 cases (22.2%) vs.16 cases (44.4%), χ2=4.000, P=0.046] and stage Ⅰ-Ⅱ ROP [11 cases (30.6%) vs.22 cases (61.1%), χ2=6.769, P=0.009] in the LISA group was significantly lower than that of the INSURE group.There was no significant difference in the incidence of moderate and severe BPD and stageⅢ ROP and above between groups (all P>0.05). (2)There were no statistical differences in the repeated use of PS, mechanical ventilation rate within 72 h, pneumothorax/pulmonary hemorrhage, grade Ⅲ-Ⅳ periventricula-rintraventricular hemorrhage, stage Ⅱ-Ⅲ neonatal necrotizing enterocolitis, sepsis, abnormal amplitude integrated electroencephalogram, mortality in 36 weeks of corrected gestational age, total oxygen inhalation duration and hospitalization duration between the two groups (all P>0.05). (3)Follow-up within 1 year of corrected age after discharge.There were no significant differences in extrauterine body mass, body length and head circumference development, visual development, hearing development, Neonatal Behavioral Neurological Assessment score at corrected gestational age of 40 weeks, Bayley Scales of Infants Development score at corrected gestational age of 6 months and age of 1 year, pneumonia and re-hospitalization due to respiratory diseases between groups (all P>0.05). Conclusions:PS administration with LISA technology can reduce the incidence of mild BPD and stage Ⅰ-Ⅱ ROP in premature infants with NRDS who had the gestational age of 24-31 + 6 weeks and birth weight<1 500 g, without increasing the risk of other complications.The long-term prognosis of them treated with PS administration with LISA and INSURE is similar.

OBJECTIVES: To investigate the prevalence rate of non-alcoholic fatty liver disease (NAFLD) in overweight/obese children who visit a hospital, and to explore the influencing factors of NAFLD, in order to provide a basis for the prevention of NAFLD in overweight/obese children. METHODS: Overweight/obese children who visited Hunan Children's Hospital from June 2019 to September 2021 were recruited. The prevalence rate of NAFLD was examined. Logistic regression analysis was used to explore the factors influencing the development of NAFLD [non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH)]. Receiver operating characteristic curve analysis was used to evaluate the predictive value of the influencing factors for NAFL and NASH. RESULTS: A total of 844 overweight/obese children aged 6-17 years were enrolled. The prevalence rate of NAFLD in overweight/obese children was 38.2% (322/844), among which the prevalence rates of NAFL and NASH were 28.8% (243/844) and 9.4% (79/844), respectively. Multivariate logistic regression analysis showed that the increase of waist-to-hip ratio (WHR) and low high-density lipoprotein cholesterol (HDL-C) were associated with the development of NAFL and NASH (P<0.05). The receiver operating characteristic curve analysis showed that the combined measurement of WHR and HDL-C had a predictive value for NAFL (area under the curve: 0.653, 95%CI: 0.613-0.694), and for NASH (area under the curve: 0.771, 95%CI: 0.723-0.819). CONCLUSIONS The prevalence rate of NAFLD in overweight/obese children who visit a hospital is high. WHR and HDL-C are associated with the development of NAFLD and the combined measurement of WHR and HDL-C has a certain value for predicating the development of NAFLD.
