Objective: To investigate the resistance to rifampicin and isoniazid and the changing trends among patients with pulmonary tuberculosis in Luohu District, Shenzhen City, Guangdong Province from 2012 to 2022, so as to provide insights into improving drug-resistant pulmonary tuberculosis control and prevention strategies. Methods: Basic information, treatment classification and drug resistance data of patients with pulmonary tuberculosis and positive pathogenic detection in Luohu District from 2012 to 2022 were collected through the Tuberculosis Surveillance System of Chinese Disease Prevention and Control Information System, and resistance rates of rifampicin and isoniazid and the changing trends were analyzed. Results: A total of 2 126 patients with pulmonary tuberculosis were collected and had a median age of 34 (interquartile range, 25) years, including 1 334 males (62.75%) and 792 females (37.25%). There were 302 patients with drug-resistance in Luohu District from 2012 to 2022, with a resistance rate of 14.21%. Among them, 60 patients were monoresistant to rifampicin (2.82%), 113 patients were monoresistant to isoniazid (5.32%), and 129 patients were multidrug resistant (6.07%). The rate of rifampicin monoresistance showed a downward trend from 2012 to 2022, while the rate of multidrug resistance showed an upward trend (both P<0.05). There was no significant tendency in the rate of isoniazid monoresistance (P>0.05). The rate of multidrug resistance among patients without Shenzhen residence was higher than that among patients with Shenzhen residence; the rates of rifampicin resistance and multidrug resistance among retreated patients were higher than those among treatment-naïve patients (all P<0.05). Conclusions The rate of rifampicin monoresistance appeared a downward trend and the rate of multidrug resistance appeared an upward trend among patients with pulmonary tuberculosis in Luohu District from 2012 to 2022. Attention should be given to non-Shenzhen residence and retreated patients.

Objective:To investigate the relationship between serum osteopontin (OPN), bone morphogenetic protein 2 (BMP2), retinol binding protein 4 (RBP4) and renal function and bone mineral density in patients with diabetes nephropathy (DN).Methods:A total of 120 patients with DN diagnosed in the Affiliated Hospital of Jining Medical University from January 2020 to December 2021 were selected as the DN group, 60 patients with simple diabetes as the type 2 diabetes mellitus (T2DM) group, and 60 subjects with normal glucose tolerance test as the control group. The serum OPN, BMP2, RBP4, low bone mineral density (LBMD), femoral neck bone density (FNBMD) and renal function indicators of the three groups were compared. According to the urinary albumin excretion rate (UAER) of DN patients, the patients were divided into microalbuminuria DN group (71 cases) and massive albuminuria DN group (49 cases), and stratified comparison was made. The simple linear correlation analysis was used to analyze the OPN of DN patients. BMP2, RBP4, renal function and bone mineral density.Results:The fasting blood glucose (FPG), glycated hemoglobin (HbA 1c), serum creatinine (Scr), UAER, and cystatin (CysC) levels of DN group patients were significantly higher than those of T2DM group and control group, and the differences were statistically significant (all P<0.05); The FPG and HbA 1c in the T2DM group were higher than those in the control group, and the differences were statistically significant (all P<0.05); The OPN and BMP2 of DN group patients were higher than those of T2DM group and control group, while the RBP4, LBMD, FNBMD of DN group were lower than those of T2DM group and control group, and the differences were statistically significant (all P<0.05); The OPN and BMP2 of the T2DM group were higher than those of the control group, while RBP4 was lower than that of the control group, and the differences were statistically significant (all P<0.05); The levels of FPG, HbA 1c, Scr, UAER, and CysC in patients with macroalbuminuria DN were significantly higher than those in patients with microalbuminuria DN, and the differences were statistically significant (all P<0.05); The OPN and BMP2 of patients in the large albuminuria DN group were higher than those in the microalbuminuria DN group, while the RBP4, LBMD, and FNBMD of patients in the large albuminuria DN group were lower than those in the microalbuminuria DN group, and the differences were statistically significant (all P<0.05). The OPN of DN group patients was positively correlated with Scr, UAER, and CysC (all P<0.05), while BMP2 was positively correlated with UAER and CysC (all P<0.05); The OPN and BMP2 of DN group patients were negatively correlated with LBMD and FNBMD (all P<0.05), while RBP4 was positively correlated with LBMD and FNBMD (all P<0.05). Conclusions:OPN, BMP2, RBP4 are closely related to the degree of renal function impairment and bone loss in DN patients, and can to some extent reflect the degree of bone metabolism and osteoporosis in T2DM patients.

Objective:To explore the predictive value of amplitude integrated electroencephalography(aEEG)in the neurological prognosis of children with neonatal bacterial meningitis(NBM).Methods:The clinical data and aEEG results from 148 children diagnosed with NBM who completed aEEG examinations in the Department of Neonatology at Kunming Children′s Hospital from January 2018 to December 2019 were retrospectively analyzed.According to whether aEEG is abnormal, the children were divided into aEEG abnormal group and aEEG non-abnormal group.According to the degree of aEEG abnormality, children with aEEG abnormality were divided into aEEG mild abnormal group and aEEG severe abnormal group.The abnormal rate and abnormal characteristics of aEEG were analyzed; The clinical data of two groups were compared.Results:(1)Among the 148 children with NBM, 49 children had abnormal aEEG, 99 children had no abnormality, and the aEEG abnormal rate was 33.1%.The abnormal aEEG was manifested as delayed sleep-wake cycle maturation in 39 (26.3%) cases, abnormal discharge in eight (5.4%) cases, and abnormal background activity in one (0.6%) case.(2)The proportion of children with convulsive seizures and refractory NBM in aEEG abnormal group were significantly higher than those in aEEG non-abnormal group ( P<0.05). In the routine and biochemical abnormal indexes of cerebrospinal fluid, the proportion of protein >3 g/L, cerebrospinal fluid leukocyte>500×10 6/L, cerebrospinal fluid glucose<1.5 mmol/L, positive cerebrospinal fluid culture, positive blood and cerebrospinal fluid culture, abnormal head MRI in aEEG abnormal group significantly increased ( P<0.05); While there was no significant difference regarding blood routine leukocyte abnormality, CRP increase, and positive blood culture ratio between two groups ( P>0.05). (3) 148 cases of NBM children were followed up to 15 months old, 119 (80.4%) cases completed the follow-up, the loss rate was 19.6%, three cases died, and 11 cases had psychomotor retardation.Compared with the children with abnormal aEEG, the prognosis of children with NBM was significantly different, the Spearman rank correlation coefficient r was 0.315 ( P<0.05). COX regression was used to analyze the predictive value of each index for adverse outcomes. Abnormal aEEG was an independent risk factor for adverse outcomes in children with NBM ( OR=7.452, 95% CI 1.605-34.591, P<0.05). Conclusion:The aEEG monitoring of children with NBM, if abnormal, may indicate severe NBM, which is likely to be transformed into refractory NBM or has a poor prognosis.

Objective To analyze the quality control data of linear accelerator detected by Daily QA3 and to evaluate this quality control process using statistical process control.Methods After the calibrations of the accelerator and Daily QA3,Daily QA3 device was used to perform daily quality control by technicians and physicists and 100 groups and 30 groups of daily quality control data were collected.After the accelerator and Daily QA3 were re-calibrated,Daily QA3 device was utilized to perform daily quality control by technicians and 100 groups of the daily quality control data were repeatedly collected.The variations of normalized signal-to-noise ratio of quality control data collected after two calibrations were analyzed.The first 30 groups of daily quality control data measured by technicians and physicists were adopted to calculate the I-MR control chartsand compare the location of CL and the range of UCL and LCL.The process capability indices were calculated for three different quality control processes bytechnicians and physicists,respectively.Results For twice calibrations,normalized signal-to-noise ratio of quality control data significantly changed before 6 weeks,became stable between 6 and 8 weeks,and the changes became smaller after 8 weeks.For dose output measured by physicists,the rang of UCL and LCL was more narrow.In terms of flatness and symmetry,the location of CL was closer to zero.Regarding dose output and flatness,the process capability indices of three different quality control process were all satisfied ≥ 1,whereas unsatisfied for transverse symmetry.Conclusions The first 30-40 data points should be adopted to delineate I-MR control chart of the linear accelerator in daily quality control process.The quality control process should be completed by a fixed and small group of personnel and an optimal tolerance level should be customized.

Objective: To explore the relationship between glycemic control and visceral adiposity index (VAI) among type 2 diabetes mellitus (T2DM) patients.Methods: A community-based epidemiological field study for patients with T2DM aged ≥ 40 years was conducted in China.Every participant underwent physical examinations, biochemical tests of fasting glucose, glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and so on, and a questionnaire, including anthropometric characteristics, lifestyle, disease history, family history, and medication use.Those participants with HbA1c ≥7.0% were classified as the poorly controlled in our analysis of relationship between glycemic control and VAI.Anthropometric characteristics, lifestyle, and biochemical indexes of the participants were compared among the groups of different VAI levels.Logistic models were applied in multiple analysis adjusting for possible confounders.Results: A total of 1 607 patients with T2DM were recruited in our analysis with a mean age of (59.4±8.1) years and an average T2DM duration of (7.0±6.4) years.Among them, 78.3% were on hypoglycemic therapy.The cutoff points of quartiles of VAI were calculated for the males and females, respectively.According to the ascending order of the quartiles of VAI, the participants were divided into four groups, i.e.Q1, Q2, Q3, and Q4.The poor glycemic control rate for these groups were 60.6%, 65.7%, 70.1%, and 71.0%, respectively (Trend χ2=12.20, P<0.001).After adjustment for age, gender, systolic blood pressure (SBP), diastolic blood pressure (DBP), LDL-C, smoking, cardio-cerebral vascular disease (CVD) history, hypoglycemic therapy, T2DM duration, and family history of diabetes, the Logistic regression models showed that the glycemic control rate was significantly associated with VAI levels among the patients with T2DM.Compared with the participants in group Q1, the ORs of poor glycemic control for those in groups Q2, Q3, and Q4 were 1.239 (95%CI 0.918 to 1.672), 1.513 (95%CI 1.117 to 2.050), and 1.535 (95%CI 1.128to 2.088), respectively (trend P=0.003).With each quartile increase in VAI, the OR of poor glycemic control was 1.162 (95%CI 1.054 to 1.282).Conclusion: The glycemic control among the patients with T2DM is significantly associated with VAI.High level of VAI is an indicator of poor glycemic control.

Objective: To investigate the clincopathologic and immunohistochemical features of gastric glomus tumors and their differences from gastric neuroendocrine neoplasms. Methods: Six cases of gastric glomus tumors, 8 cases of glomus tumors in other sites and 7 cases of gastric neuroendocrine neoplasms were collected from the Department of Pathology, Taizhou Hospital. The clinicopathological and immunohistochemical characteristics of these tumors were analyzed retrospectively. Results: The gastric glomus tumors were located in the muscularis propria of the antrum and most cases strongly expressed synaptophysin (5/6). However, no synaptophysin expression was seen in glomus tumors of other organs.Most gastric neuroendocrine neoplasms were located in the mucosa or submucosa of the fundus and corpus. In addition to the strong expression of synaptophysin (7/7), CgA (6/7) and CD56(5/7) were strongly positive, although SMA was negative. Conclusions Gastric glomus tumors and neuroendocrine neoplasms have similar morphological characteristics and both show strongly expression of synaptophysin. However, the location and immunohistochemical characteristics of gastric glomus tumors differ from those of the neuroendocrine neoplasms.

Objective The aim of this study is to understand the impairment and compensation mechanism of brain function in untreated primary insomnia (PI) patients.The approach of fractional amplitude of low frequency fluctuation (fALFF) is used to analyze raw data between the PI patients and the normal control group in resting state using functional magnetic resonance imaging (fMRI).Methods Fifty-nine PI patients,admitted to our hospital from November 2015 to November 2016,and 47 age-,education-,and gender-matched normal healthy subjects were chosen in our study.Pittsburg sleep quality index (PSQI),insomnia severity index (ISI) were employed to evaluate the sleep quality.Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were employed to evaluate the emotion.Resting state fMRI and fALFF analyses were used to compare the functional regional activities.The correlations of fALFF data with PSQI,SAS and SDS scores were analyzed.Results In PI patients,2 had mild to moderate insomnia,41 had moderate insomnia,and 16 had serious insomnia.ISI scores in the normal healthy subjects were less than 7.The PSQI,SAS,SDS and ISI scores in the PI patients were significantly higher than those in the normal healthy subjects (P＜0.05).As compared with the control group,the PI group had significantly increased fALFF value in the right hippocampus (HIP),right parahippocampa gyms,right amygdala,and bilateral thalamus.The fALFF value was positively correlated PSQI,SASandSDSscores (r=0.582,P=0.000;r=0.617,P=0.000;r=0.653,P=0.000).Conclusion Some brain regions in the PI patients are abnormal in the resting state,which can reflex functional regional activities of PI patients.
