Abstract: Objective To investigate the nutritional status of patients with pulmonary tuberculosis and its effects on conventional anti-tuberculosis treatment, so as to provide a basis for improving the efficacy of conventional treatment of pulmonary tuberculosis. Methods The relevant data of 168 patients with pulmonary tuberculosis admitted to Suining Central Hospital from April 2020 to April 2022 were retrospectively analyzed. Nutritional status of the patients before treatment was investigated using the Mini Nutritional Assessment (MNA) score, and the influencing factors of nutritional status before treatment were analyzed. Therapeutic effects of anti-tuberculosis drugs in the non-nutritional risk group and the nutritional risk group were comparatively analyzed. Results Among the 168 patients, 64 were assessed as having good nutritional status before treatment, 59 had the risk of malnutrition and 45 were malnourished according to the MNA score. Univariate analysis and linear regression analysis showed that age, underlying diseases, and clinical symptoms were factors affecting the MNA score before treatment (t=3.173, 3.718, 2.018, P all<0.05); whereas gender and education level were not factors affecting MNA score before treatment (t=0.065, 0.059, P all>0.05). According to the MNA score before treatment, the patients were dividedinto a non-nutritional risk group (MNA score > 23.5) and a nutritional risk group (MNA score ≤23.5). The negative conversion rate of sputum bacteria, effective rate of focal absorption in the non-nutritional risk group were 92.19% (59/64)and90.63% (58/64) , respectively, which were significantly higher than corresponding 79.85% (82/104)and76.92% (80/104) in the nutritional risk group. The drug resistance rate, adverse reaction rate, and average treatment cost of the no nutritional risk group and nutritional risk group were 7.81% (5/64) and 21.15% (12/104), 15.63% (10/64) and 31.73% (33/104), (0.62±0.13) million yuan and (0.89±0.26) million yuan, respectively, with significant differences (χ2=5.228, 5.071, 7.685, 5.396, 7.728, P all<0.05). Conclusions Patients with pulmonary tuberculosis exhibit poor nutritional status before treatment. The patients’nutritional status is easily affected by age, underlying diseases, and clinical symptoms, thereby affecting the effect of anti-tuberculosis treatment. Therefore, early nutritional intervention for tuberculosis patients should be recommended in order to prevent malnutrition and enhance the effectiveness of anti-tuberculosis treatment.

BACKGROUND: Seizures are common following many cerebral insults, include global and focal ischemia. However, while the mechanism must relate to some change in the relative activities of excitatory and inhibitory pathway, the specific alterations in neurotransmitter concentrations and/or receptor sensitivities which underlie these events, remain unknown. The principal aim of this study was therefore to evaluate the effects of moderately severe forebrain ischemia on lidocaine-induced seizure thresholds, in hopes of gaining some insights into these processes. METHODS: Halothane-anesthetized, normothermic Sprague-Dawley rats were chronically instrumented with screw electrodes and vascular catheters, and were then subjected to 10 min of forebrain ischemia, produced by bilateral carotid occlusion combined with hypotension (MAP = 30 mmHg). After reperfusion, animals were awakened. 6, 24 and 46 hours later, separate groups of awake animals were subjected to intravenous infusion of lidocaine at the rate of 2.6 mg/kg/min. The total dose of lidocaine infused prior to generalized tonic-clonic seizures were noted. Another group of Sham animals (no ischemia) served as control. RESULTS: The lidocaine-induced seizure threshold was significantly increased at 24 h after forebrain ischemia (65.39 12.9 mg/kg vs 36.47 4.24 mg/kg, P < 0.05). Interestingly, at 6 h post-ischemia, rats treated with lidocaine consistently died before seizures. There were no significant differences in seizure threshold between the control and 48 h post-ischemia groups. CONCLUSIONS: Ten minutes of forebrain ischemia is followed by a transient increase in the seizure threshold to infused lidocaine. By 48 h following reperfusion, lidocaine induced seizure threshold had returned to normal.

Objective To evaluate the effects of different smoking cessation interventions on cigarette consumption for young soldiers.Methods Sixty-eight soldiers were prospectively investigated in this randomly controlled clinical trial and assigned to the psychological intervention group,auricular acupuncture group,and smoking cessation medication group.Results All the participants showed significant reduction(33.3％ to 73.9％)in post-treatment cigarette consumption.The highest quit rate was found at 7 days,although this declining trend was faded over time.One-year follow-up indicated a 6-month quit rate of 16.7％,23.8％ and 30.4％ in three groups,respectively.Conclusion Psychological intervention,auricular acupuncture and smoking cessation medication may be effective methods of reducing cigarette consumption and improving quit rate in young soldiers.

Objective To investigate the value of the intraoperative real-time three-dimensional transesophageal echocardiography (RT 3D-TEE) in therapeutic application of surgery for the mitral valve prolapse.Methods Thirty-five patients underwent surgical treatment were diagnosed as mitral valve prolapse by 2-dimensional transthoracic echocardiography (2D-TTE),with or without ruptured chordae tendineae.RT 3D-TEE was performed for assessing the segment of prolapse and its complications before cardiopulmonary bypass and after heart resuscitation respectively.The echocardiographic results were compared with the surgical findings.Results The accuracy of RT 3D-TEE to identify segments with prolapse was significantly higher than that of 2D-TTE (91.4％ vs 82.9％,P =0.003).RT 3D-TEE was more accurate than 2D-TTE for identifying ruptured chordae tendineae,vegetation and thrombus since higher sensitivity,specificity and Youden index.Among all 35 patients,valvuloplasty was performed in 28 cases,whereas,only 7 cases underwent replacement of prosthetic valves.Three patients were benefited by accurate evaluation of therapeutic effect using RT 3D-TEE in time.ConclusionsIntraoperative RT 3D-TEE can be used to provide “ surgical view”,acquired adequate valuable information of mitral valve,and more reliable functional and anatomical assessment of the mitral valve components and its geometry.Suitable surgical intervention can be designed for improving outcomes of patients.

OBJECTIVE To invest igate the correlation between fractional exhaled nitric oxide(FeNO) and lung function in artemisia argyi allergy patients. Whether the course of disease and rhinitis score are correlated with FeNO and lung function. METHODS A total of 88 patients with mugwort pollen allergy, who visited the hospital between August and September 2017 and August and September 2018, the results of their FeNO and Pulmonary ventilation function, were included in this study. RESULTS Compared with patients with a duration of 9 years or more, FeNO and FEV1％ of patients with a duration of 5 years were significantly different(P =0.004, P =0.032), and FeNO increased with the extension of the duration, while FEV1％ decreased gradually. FeNO was negatively correlated with FEF25％-75％pred and FEV1％, while there was no correlation with FEV1％pred. Rhinitis score was positively correlated with FeNO. There was no correlation with FEV1％pred, FEV1％, FEF25％-75％pred. CONCLUSION With the development of mugwort pollen allergy, the probability of airflow limitation is also increased. To some extent, FeNO can predict the changes of airway function early, and can be used as a monitoring indicator for asthma prediction.FeNO value can reflect the degree of inflammation of the body, and can be used in the auxiliary diagnosis of the severity of allergic rhinitis patients.
