Tuberculosis is caused by Mycobacterium tuberculosis,and the problem of its drug resistance has become increasingly prominent in recent years,attracting widespread attention globally.Currently,the situation of drug-resistant tuberculosis is grim,and effective strategies are urgently needed to deal with it.Understanding the drug resistance mechanism and treatment status of drug-resistant tuberculosis can provide an important basis for clinical prevention and treatment of drug-resistant tuberculosis.This paper reviews the progress of drug resistance mechanism and treatment of drug-resistant tuberculosis,in order to provide a reference for clinical intervention.

Objective To investigate the effect of interaction between serum neutrophil gelatinase-associat-ed lipid carrier protein(NGAL)and complications after percutaneous coronary intervention(PCI)on poor prognosis in patients with ST-segment elevation myocardial infarction(STEMI),and to provide reference for improving prognosis.Methods From January 2017 to January 2020,a total of 400 STEMI patients admitted to this hospital were selected and divided into good prognosis group(n=378)and poor prognosis group(n=22)according to their 2-year prognosis.Logistic regression equations were used to analyze the prognostic fac-tors of STEMI patients,and multiplicative and additive effects were established to analyze the effect of the in-teraction between serum NGAL and post-PCI complications on poor prognosis.Results Gender,age,heart rate,Gensini score,number of lesions ≥2,Killip grade,complications after PCI and NGAL level after PCI were associated with poor prognosis in STEMI patients(P＜0.05).Gender(female),age,heart rate,Gensini score,number of lesions ≥2,Killip grade,complications after PCI and NGAL level after PCI were all inde-pendent influencing factors of poor prognosis in STEMI patients(P＜0.05).There was interaction between serum NGAL after PCI and complications after PCI,both of which had an adverse effect on the prognosis of STEMI patients(P＜0.05).There was no multiplicative interaction between serum NGAL and complications after PCI(P＞0.05).When serum NGAL and complications after PCI were exposed at the same time,the risk of poor prognosis in STEMI patients was higher than the sum of the two exposures alone,and the interaction was 2.611 times the sum of the effects of the two exposures alone.Conclusion Serum NGAL and postopera-tive complications after PCI are independent factors influencing poor prognosis in STEMI patients.There is a additive interaction between the two factors,and exposure can increase the risk of poor prognosis.

Objective To explore the clinical effect of honey in preoperative bowel preparation for colonoscopy in hospitalized patients.Methods 87 patients from April 2022 to July 2022 and underwent preoperative bowel preparation for colonoscopy were selected as the research subjects.Convenience sampling was used to divide them into a control group(n=43)and an observation group(n=44).The control group received a conventional regimen of taking compound polyethylene glycol(PEG)electrolyte powder(Heshuang),while the observation group added 20 mL of honey to the Heshuang solution.Compare the cleanliness of intestine,and palatability of the taste,the incidence of adverse reactions,satisfaction of patients,and the rate of willingness for prepeat bowel preparation between the two groups.Results The intestinal cleanliness of the two groups of patients was equivalent,the difference was not statistically significant(P＞0.05).The incidence and severity of nausea,abdominal bloating,hypoglycemia,and anal irritation in the observation group were lower than those in the control group,the differences were statistically significant(P＜0.05).The observation group had better taste,patients satisfaction,and the willingness for prepeat bowel preparation compared to the control group,the differences were statistically significant(P＜0.05).Conclusion Honey can improve the taste of Heshuang,reduce the severity of oral adverse reactions,increase patient satisfaction,and increase the rate of willingness for prepeat bowel preparation.

Background/Aims: Intestinal Behçet disease is typically associated with ileocecal punched-out ulcers and significant morbidity and mortality. Intestinal ultrasound is a noninvasive imaging technique for disease monitoring. However, no previous reports have compared intestinal ultrasound with endoscopic ulcer activity or histopathological findings for intestinal Behçet disease. We evaluated the usefulness of intestinal ultrasound for assessing the activity of ileocecal ulcers in intestinal Behçet disease. Methods: We retrospectively compared intestinal ultrasound findings with 73 corresponding endoscopic images and 6 resected specimens. The intestinal ultrasound findings were assessed for 7 parameters (bowel wall thickness, vascularity [evaluated using the modified Limberg score with color Doppler], bowel wall stratification, white-plaque sign [strong hyperechogenic lines or spots], mesenteric lymphadenopathy, extramural phlegmons, and fistulas), and endoscopic ulcer activity was classified into active, healing, and scar stages. Histopathological findings were evaluated by consensus among experienced pathologists. Results: Bowel wall thickness (P< 0.001), vascularity (P< 0.001), loss of bowel wall stratification (P= 0.015), and white-plague sign (P= 0.013) were significantly exacerbated in the endoscopic active ulcer stage. Receiver operating characteristic curve analysis revealed that a bowel wall thickness of > 5.5 mm (sensitivity 89.7%, specificity 85.3%) was potentially useful for detecting active lesions. When compared with histopathological findings, an increase in bowel wall thickness reflected the ulcer marginal ridge, and the white-plaque sign reflected the ulcer bottom. Conclusions Intestinal ultrasound is useful for monitoring intestinal ulcer activity in intestinal Behçet disease.

Objective:To explore the clinical application value of salivary pepsin test (Peptest) in the diagnosis of gastroesophageal reflux disease (GERD).Methods:From April to October 2022, at the Department of Gastroenterology of the First Affiliated Hospital of Nanjing Medical University, a total of 81 patients with typical reflux and (or) heartburn symptoms for more than 1 month, who were diagnosed with GERD and completed 24-hour esophageal pH impedance monitoring (24 h MII-pH) and high-resolution esophageal manometry were enrolled. Salivary samples were collected after lunch, at the onset of symptoms, and at random time point on the day of intubation, and all patients received standard dose of proton pump inhibitor (PPI) for 2 weeks. The 24 h MII-pH results were taken as the gold standard for diagnosing GERD. The optimal time point of Peptest and the diagnostic value of combination of Peptest and PPI test in GERD diagnosis were analyzed. The 24 h MII-pH negative patients were further divided into Peptest-positive group and Peptest-negative group. The heartbrun scores, gastroesophageal reflux disease questionnaire (GERD-Q), reflux characteristics, and esophageal motility between the 2 groups were compared and to investigate the differential diagnostic value of Peptest in 24 h MII-pH negative patients. Chi-square test and non-parametric test were used for statistical analysis.Results:The results of 24 h MII-pH indicated that 21 patients (25.9%, 21/81) were diagnosed GERD and 60 patients were negative for 24 h MII-pH. The onset of symptoms was the optimal time point for Peptest, with a sensitivity of 80.9%, a specificity of 50.0%, and an accuracy of 58.0%. The specificity and accuracy of Peptest at the onset of symptoms combined with PPI test in GERD diagnosis were higher than those of Peptest at the onset of symptoms alone (75.0% vs. 50.0%, 74.1% vs. 58.0%), and the differences were statistically significant ( χ2=8.00 and 4.65, P=0.005 and 0.031). Among 60 cases of 24 h MII-pH negative patients, 30 were positive for Peptest at the onset of symptoms and 30 were negative for Peptest at the onset of symptoms. The heartburn scores and GERD-Q scores of Peptest-positive group were both higher than those of Peptest-negative group (3.0 (2.0, 3.0) vs. 1.0 (0.0, 2.3), 12.0 (9.8, 13.0) vs. 9.0 (6.0, 11.0) ); the clearance time of acid reflux of Peptest-positive group was longer than that of Peptest-negative group (57.0 s (22.3 s, 88.0 s) vs. 18.3 s (9.6 s, 32.1 s) ); the lower esophageal sphincter resting pressure and integrated relaxation pressure were lower than those of Peptest-negative group (10.40 mmHg (5.75 mmHg, 18.95 mmHg) vs. 21.45 mmHg (10.65 mmHg, 31.70 mmHg), 3.90 mmHg (2.05 mmHg, 5.35 mmHg) vs. 4.90 mmHg (3.76 mmHg, 8.25 mmHg); 1 mmHg=0.133 kPa); the distal mean nocturnal baseline impedance, the distal contractile integral and esophagogastric junction contractile integral were all lower than those of Peptest-negative group ( 1 783 Ω (1 660 Ω, 2 157 Ω) vs. 2 300 Ω(1 805 Ω, 2 370 Ω), 1 416 mmHg·s·cm (919 mmHg·s·cm, 2 176 mmHg·s·cm) vs. 1 858 mmHg·s·cm (1 395 mmHg·s·cm, 2 880 mmHg·s·cm), 27.7 mmHg·cm (19.8 mmHg·cm, 39.5 mmHg·cm) vs. 52.6 mmHg·cm (27.7 mmHg·cm, 74.6 mmHg·cm) ), and the differences were statistically significant ( Z=-4.00, -3.53, -3.31, -2.34, -2.13, -2.75, -2.14 and -2.43; P<0.001, <0.001, =0.001, =0.019, =0.033, =0.006, =0.032 and =0.015). Conclusions:Peptest may be better at diagnosing GERD at the onset of symptoms compared to postprandial, random time points, and the accuracy of diagnosing GERD further improves when combined with PPI test. Peptest at the onset of symptoms may have differential diagnostic value for GERD patients in 24 h MII-pH negative patients.

Objective: The etiology of schizophrenia is unknown and is associated with abnormal spontaneous brain activity. There are no consistent results regarding the change in spontaneous brain activity of people with schizophrenia. In this study, we determined the specific changes in the amplitude of low-frequency fluctuation/fractional amplitude of low-frequency fluctuation (ALFF/fALFF) and regional homogeneity (ReHo) in patients with drug-naïve first-episode schizophrenia (Dn-FES). Methods: A comprehensive search of databases such as PubMed, Web of Science, and Embase was conducted to find articles on resting-state functional magnetic resonance imaging using ALFF/fALFF and ReHo in schizophrenia patients compared to healthy controls (HCs) and then, anatomical/activation likelihood estimation was performed. Results: Eighteen eligible studies were included in this meta-analysis. Compared to the spontaneous brain activity of HCs, we found changes in spontaneous brain activity in Dn-FES based on these two methods, mainly including the frontal lobe, putamen, lateral globus pallidus, insula, cerebellum, and posterior cingulate cortex. Conclusion We found that widespread abnormalities of spontaneous brain activity occur in the early stages of the onset of schizophrenia and may provide a reference for the early intervention of schizophrenia.

OBJECTIVE: To evaluate the effect of standardized health education on the sputum specimen collection rate for nucleic acid detection of coronavirus disease 2019 (COVID-19). METHODS: Two hundred and twenty-seven patients in fever clinics and isolation wards of Sir Run Run Shaw Hospital of Zhejiang University and 307 migrant workers returning to 5 enterprises in Shanghai from February 3 to March 14, 2020 were enrolled in the study. Through clarifying the procedures of collecting sputum specimens, making graphic/video health education materials, standardizing the contents and methods of health education, we conducted education to the subjects. The subject expectorated spontaneously or with medical assistance. For patients, the number of sampling attempts and sputum acquisition times were documented before and after the implementation of the standardized expectoration method; for the returning migrant employees in the enterprises, only the number of collected samples after the implementation of the standardized expectoration method were recorded. RESULTS: A total of 378 sputum samples were collected from 227 patients. The sputum sampling rates before and after the implementation of health education were 40.9%and 58.4%, respectively ( CONCLUSIONS The education for standardized sputum sample collection method can effectively increase the sputum collection rate.

Objective To investigate the effects of dexmedetomidine postconditioning on brain injury after cardiac arrest and resuscitation in a swine model.Methods Twenty-eight healthy male domestic pigs,weighing 36±2 kg,were randomized (random number) into 4 groups (n=7 each group):sham operation group (S group),cardiopulmonary resuscitation group (CPR group),low-dose dexmedetomidine postconditioning group (LDP group),and high-dose dexmedetomidine postconditioning group (HDP group).Animals in the S group only underwent the surgical preparation.In the other three groups,the experimental model was established by 8 mins of electrically induced ventricular fibrillation and then 5 mins of cardiopulmonary resuscitation.At 5 min after resuscitation,a loading dose of dexmedetomidine of 0.25 μg/kg was intravenously infused followed by continuous infusion at a rate of 0.25 μg/(kg·h) for 6 h in the LDP group,and a loading dose of dexmedetomidine of 0.5 μ.g/kg was infused followed by continuous infusion at a rate of 0.5 μg/(kg·h) for 6 h in the HDP group.The same amount of normal saline was administered in the S and CPR groups.At 1 h,3 h,6 h and 24 h after resuscitation,the levels of serum neuron specific enolase (NSE) and S100B protein were measured.At 24 h after resuscitation,neurologic deficit score (NSD) was evaluated.After that,the animals were euthanized and cerebral cortex was obtained for the determination of tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6)and malondialdehyde (MDA) contents,superoxide dismutase (SOD) activity,cell apoptosis and caspase-3 expression.Results Compared with the S group,post-resuscitation neurologic dysfunction and brain injury were observed in the other three groups,which were indicated by significantly higher NDS and markedly greater levels of serum NSE and S 100B (all P＜0.05).Compared with the CPR group,the score of NDS at 24 h post-resuscitation were significantly lower and the levels of serum NSE and S100B at 6 h and 24 h post-resuscitation were significantly less in the LDP and HDP groups [NDS:194±26,103±16 vs 278±23 at 24 h;NSE (ng/mL):32.4±1.8,28.6±3.7 vs 36.2±2.8 at 6 h,39.9±4.2,35.1±1.5 vs 45.1±3.0 at 24 h;S100B (pg/mL):2 534±207,2 382±170 vs 2 825±113 at 6 h,3 719±164,3 246±176 vs 4 085±161 at 24 h,all P＜0.05].Compared with the LDP group,neurologic dysfunction and brain injury at 24 h postresuscitation were further significantly alleviated in the HDP group (all P＜0.05).Pathological analysis indicated that brain inflammation,oxidative stress and cell apoptosis were observed after resuscitation in the CPR,LDP and HDP groups.However,the contents of TNF-α,IL-6 and MDA were significantly lower while the activity of SOD was significantly higher,and cell apoptosis and caspase-3 expression were significantly reduced in the brain after resuscitation in the LDP and HDP groups compared with the CPR group (all P＜0.05).In addition,those pathological injuries mentioned above were further significantly alleviated in the brain after resuscitation in the HDP group compared to the LDP group (all P＜0.05).Conclusions Dexmedetomidine postconditioning significantly alleviated the severity of postresuscitation brain injury in a dose-dependent manner,in which the protection was produced possibly through reducing tissue inflammation,oxidative stress and cell apoptosis.

OBJECTIVE： To provide reference for standardization and improvement of teaching model for endocrinology speciality in community clinical pharmacists training base. METHODS： Based on the requirments of community clinical pharmacists training in Shanghai，  the characteristics and contents of community clinical pharmacists training were summarized， and teaching characteriatiostics， effect evaluation and problems werer analyzed on the basis of the acutual situation in our hospital. RESULTS & CONCLUSIONS： Community clinical pharmacists training has the characteristics of training for chronic diseases， short training cycle， and support from the medical consortium platform. Its contents are theoretical learning and professional knowledge training， pharmaceutical care and medication education， case discussion， homework guidance and comment. Compared with other specility， endocrinology speciality has the characteristics of strengthening comprehensive pharmaceutical care （for example， pharmaceutical care of diabetic patients should pay attention not only to hypoglycemia， but also to hypobaric， hypolipidemic and complications）， emphasizing medication treatment management （MTM） teaching （provide a series of professional services such as medication education， counseling and guidance， and medical reorganization for patients， so as to improve the safety， effectiveness and compliance of medication， and then control blood glucose， delay or avoid complications）， emphasizing the cultivation of health education ability and communication ability. The evaluation of training effect included the evaluation of trainees and teachers. The former includes objective evaluation （theoretical knowledge test， bedside medication education assessment and homework assessment） and subjective evaluation （attendance， attitude， clinical practice performance）. The latter is mainly scored by trainees on teachers （including professional level， teaching attitude， teaching ability and content）. Through the training， it is found that the trainees’ literature retrieval ability is poor， the trainees have not clear idea to diabetic patients， the homework writing and typesetting are not standardized； the teaching teachers have less experience and teachers could not teach the students in accordance with their aptitude and provide individualized training. The training and teaching mode needed to be further improved.

Objective To explore the expression of long noncoding RNA ( lncRNA) RN7SK and its screening value in clinical diagno-sis of gastric cancer. Methods The expression of lncRNA RN7SK in gastric cancer cells and paired gastric cancer tissues were meas-ured by qRT-PCR. The screening efficacy was detected by the receiver operating characteristic ( ROC) curve. Results The expression levels of lncRNA RN7SK in gastric cancer lines SGC-7901(3.91±0.53),MGC-803(3.44±0.29),HGC-27(4.04±0.87)and BGC-823 (4.30±1.13) were markedly higher than that in human gastric mucosal epithelial cell line GES-1, and the difference had statistical sig-nificance(1.02±0.27, t=12.33, 7.48, 7.20 and 4.90, P<0.05). The expression of RN7SK was up-regulated in 85.5％ (47/55) of gastric cancer tissues while down-regulated in the the other 8 tissues ( 14. 5％) . The area under ROC curve ( AUCROC ) of lncRNA RN7SK expression in gastric cancer patients was 0.827 and the 95％ confidence interval (CI) was from 0.746 to 0.907. When the cut-off value was 0.618, the sensitivity and specificity were 0.836 and 0.782 respectively. Conclusion The level of lncRNA RN7SK should be overexpressed in gastric cancer tissues so that it may have high screening efficacy and could be used as a potential molecular marker for the diagnosis of gastric cancer.
