Objective To evaluate and analyze the feasibility and application effect of ^“DOTS + WeChat^” in the treatment and management of tuberculosis patients. Methods From 2018 to 2019, a total of 2 420 active pulmonary tuberculosis patients were registered in Zibo City, and 1 988 patients meeting the inclusion criteria were selected as the research subjects. 836 patients were randomly enrolled under the ^“DOTS + WeChat^” integrated management mode, while the other 1152 cases were treated with single DOTS management mode. The regular medication status, treatment and outcome, and core knowledge awareness of the two groups were analyzed by SPSS16.0 software, χ²- test and t- test methods. Result The ^“DOTS + WeChat^” comprehensive management group had higher a regular medication rate (98.80%), coincidence rate of sputum test times (95.81%), and success rate of treatment (98.68%) than the single DOTS management group (92.10%, 90.19%, and 96.53%) (P=0.000, 0.000, 0.003). The rate of medical staff participating in supervision and management in the comprehensive management group (100%) was higher than that in the single management group (75.87%) (P=0.000). The complete follow-up rate in the consolidation period (100%) and the complete whole course follow-up rate (99.76%) were both higher than those in the single management group (P=0.000, 0.001). The awareness level of core knowledge in the comprehensive management group (78.58±4.32) was higher than that in the single management group (70.70±8.02) (P=0.000). Conclusion The application of WeChat management mode has a positive effect on the treatment and management of tuberculosis patients in Zibo City. It is a feasible and effective supplement and improvement to the current tuberculosis control and management measures, which is worthy of further promotion and exploration.

OBJECTIVE To provide reference for medication therapy management （MTM） of diabetic patients complicated with cardiovascular disease. METHODS A 63-year-old male diabetic patient who suffered from temporary headache every morning after percutaneous coronary intervention （PCI） visited the neurology department of our hospital， and then was recommended to the pharmaceutical outpatient department. The pharmacists thought that the patient’s symptoms of headache， severe constipation and hyperuricemia were more likely induced by the medication used. The pharmacists further found that his atherosclerotic cardiovascular disease （ASCVD） influencing factors such as blood pressure， heart rate， blood glucose and blood lipids did not reach standard. The pharmacists provided MTM services for the patient through pharmacy inquiry and adverse drug reactions judgement， medication evaluation， medication reconciliation， medication education and pharmacy follow-up. RESULTS Through fifteen MTM services for thirteen weeks， the pharmacists reconciliated and optimized the medication therapy plan， discontinued the use of Isosorbide mononitrate sustained-release tablets， Nifedipine controlled-release tablets， and Indapamide tablets， which caused adverse drug reactions； the number of drugs was adjusted from fifteen to seven， and the symptom of headache disappeared； severe constipation had also been significantly improved， and hyperuricemia dropped to normal range. The ASCVD influencing factors of blood pressure， heart rate， fasting plasma glucose， glycosylated hemoglobin， low-density lipoprotein cholesterol and uric acid were reduced from ＞140/90 mmHg（1 mmHg＝0.133 kPa）， 70-80 beats per minute， 7.71 mmol/L， 7.2%， 2.13 mmol/L and 494 μmol/L before MTM services to ＜130/80 mmHg， 55-60 beats per minute， 6.22 mmol/L， 6.3%， 1.55 mmol/L and 348 μmol/L after MTM services. CONCLUSIONS The pharmacists providing MTM services to the patients can improve their quality of life and therapeutic efficacy， reduce medication risks， and enhance the level of rational drug use in hospitals and pharmaceutical service capabilities.

OBJECTIVETo establish a method for the determination of N-butylbenzene in the workplace atmosphere by gas chromatography.

METHODSN-butylbenzene in the workplace atmosphere was collected by activated charcoal tube, desorbed using carbon disulfide, and determined by capillary column gas chromatography.

RESULTSThe method showed a linear relationship within the range of 0∼100 µg/ml. The regression equation was y = 0.870x-0.014, with the correlation coefficient r being 0.999 9. The limit of detection was 0.32 µg/ml. The minimum detectable concentration was 0.21 mg/m³ (with sampled air volume of 1.5 L). The average spike recovery rate was 97.8%∼102.6%. The within-run precision was 3.06% and the between-run precision was 3.64%. The rate of average desorption was 99.6%. The breakthrough volume was 6.34 mg. The sampling efficiency was 100%. The samples could be stored for at least 7 days at room temperature.

OBJECTIVE: To analyze the clinical characteristics of occupational aluminum pneumoconiosis caused by aluminum fluoride dust. METHODS: The clinical data of a case of occupational aluminum pneumoconiosis caused by occupational exposure to aluminum fluoride dust was retrospectively analyzed. RESULTS: The patient had a clear history of occupational exposure to aluminum fluoride dust for 13 years. The main clinical symptoms were chest tightness, cough and expectoration. High kV posterior and anterior chest X-ray showed that the texture of both lungs was increased and blurred, and multiple small dot-shaped shadows, including round or q-shaped shadows, were seen in the both lung fields and distributed in 6 lung regions. Chest computed tomography showed that the texture of both lungs increased, and multiple small punctate high density lesions were found in both lungs. The pulmonary function examination showed the small airway ventilation dysfunction and the gas diffusion function was reduced. It was diagnosed as occupational aluminum pneumoconiosis stage Ⅱ. CONCLUSION: Aluminum fluoride-induced occupational pneumoconiosis has slow onset and lacks specificity in clinical symptoms. The chest X-ray manifestations are mainly increased pulmonary texture and small round shadows.

OBJECTIVE: To evaluate the intervention effect of mindfulness-based stress reduction(MBSR) on surgical stress of bronchoalveolar lavage(BAL) in patients with pneumoconiosis. METHODS: A total of 102 patients with pneumoconiosis who undergoing selective BAL were randomly divided into control group and MBSR group with 51 cases in each group by a convenient sampling method. The patients in the control group received routine nursing, the MBSR group received 5 times of MBSR treatment. All patients were investigated using the Self-Rating Anxiety Scale(SAS), Self-Rating Depression Scale(SDS) and Chinese Version Perceived Stress Scale(CPSS) before the first BAL and after the last BAL. RESULTS: Before the first BAL, the scores of SAS, SDS and CPSS in these two groups were compared and showed no statistical significance(P>0.05). After the last BAL, the scores of SAS, SDS and CPSS were lower in the MBSR group than that of the control group and the same group before the first BAL(P<0.01).CONCLUSION: The MBSR could effectively reduce the pressure perception level of patients with pneumoconiosis who undergoing selective BAL, improve their anxiety and depression and promote the smooth implementation of BAL.

OBJECTIVE: To investigate the effects of mindfulness-based stress reduction(MBSR) on anxiety, depression and coping style of patients with newly diagnosed silicosis. METHODS: A total of 156 cases of patients with newly diagnosed silicosis were randomly divided into the control group and the intervention group by convenient sampling method, with 78 cases in each group. Patients in the control group were given routine care only, patients in the intervention group received MBSR intervention for 8 weeks on the basis of routine care. The Self-Rating Anxiety Scale, Self-Rating Depression Scale and Medical Response Questionnaire investigated the scores of anxiety, depression and coping styles in the two groups before and after the intervention. RESULTS: Before intervention, there was no significant difference in the scores of anxiety, depression and each dimension of medical response such as facing, avoidance and resignation dimensions in the two groups(P>0.05). After intervention, the anxiety and depression scores of patients in the intervention group decreased [(54.9±3.8) vs(45.5±3.8) and(57.5±3.9) vs(48.7±3.3), respectively, P<0.01] compared with the control group. The facing dimension scores of medical response increased [(19.0±1.3) vs(21.8±1.2), P<0.01], and the scores of avoidance dimension and resignation dimension of medical response decreased [(13.0±2.9) vs(12.2±2.1) and(10.3±1.6) vs(8.0±1.5), respectively, P<0.05]. CONCLUSION: The MBSR training can improve the negative emotion such as anxiety and depression in patients with silicosis, and encourage them to cope with the disease in a positive way.

Objective To investigate the value of multi-slice spiral computed tomography (MSCT) features, along with the expression levels of epidermal growth factor receptor (EGFR) and insulin-like growth factor 1 receptor (IGF1R), in differential diagnosis of benign and malignant adrenal cortical tumors. Methods A total of 98 patients with adrenal cortical tumors admitted to Zibo Municipal Central Hospital from January 2020 to July 2024 were included in this study. All subjects underwent MSCT scans of the adrenal gland. The CT values of tumor parenchyma on plain scans and at arterial and venous phases were estimated. The surgical tumor specimens were collected for immunohistochemical staining and measurement of EGFR and IGF1R expression. The MSCT features and EGFR and IGF1R expression levels were compared among patients with different pathological types of adrenal cortical tumors. Results Of the 98 patients with adrenal cortical tumors, there were 18 cases with cortical carcinoma, 10 cases with metastatic tumors, 31 cases with pheochromocytoma, 25 cases with aldosterone-producing adenomas, and 14 cases with cortisol adenomas. The CT values of adrenal aldosterone-producing adenomas were significantly lower than other pathological types of adrenal cortical tumors on plain scans and at arterial and venous phases (P < 0.05). The CT values of metastatic tumors and cortical carcinoma were significantly lower than those of pheochromocytoma and cortisol adenomas at arterial and venous phases (P < 0.05). Specifically, at arterial and venous phases, the CT values of metastatic tumors were lower than those of cortical carcinoma, and the CT values of cortisol adenomas were lower than those of pheochromocytoma (P < 0.05). The positive expression levels of EGFR and IGF1R were higher in tumor specimens from patients with metastatic tumors and cortical carcinomas than from pheochromocytoma, aldosterone-producing adenomas, and cortisol adenomas (P < 0.05). There were no significant differences between patients with metastatic tumors and cortical carcinomas in terms of positive EGFR and IGF1R expression (P > 0.05). In addition, there were no significant differences in the proportions of positive EGFR and IGF1R expression among patients with malignant adrenal cortical tumors in terms of ages, genders, tumor sizes, and TNM stages (P > 0.05). Conclusion The CT values of MSCT scans at arterial and venous phases as well as EGFR and IGF1R expression levels correlate with the pathological types of adrenal cortical tumors.

Objective To analyze the quality of malaria blood smears from fever patients in Zibo City from 2011 to 2018, so as to provide the scientific evidence for the development of the malaria post-elimination surveillance strategy. MethodsAll negative malaria blood smears from fever patients reexamined in the municipal microscopic examination station and all positive blood smears in Zibo City during the period from 2011 to 2018 were reexamined, and the blood smear preparation, dyeing, cleanliness and reexamination results were analyzed. Results A total of 2 141 negative malaria blood smears and 39 positive blood smears were re-reviewed by the municipal microscopic examination station of Zibo City from 2011 to 2018, with a 99.44% qualification rate of negative blood smears preparation, a 97.62% qualification rate of dyeing, a 93.65% qualification rate of cleanliness, and a 100% consistence with the re-review, and no missing diagnosis was found. A total of 39 positive blood smears were re-reviewed, with a 46.15% qualification rate of blood smears preparation, a 61.54% qualification rate of dyeing, a 76.92% qualification rate of cleanliness, and a 97.44% consistence with the re-review, and a blood smear mistaking the Plasmodium species was found. There were significant differences in the qualification rate of blood smears preparation and dyeing among all districts (counties) in Zibo City (all P values < 0.05), and no significant difference was detected in the qualification rate of blood smear cleanliness (χ² = 13.72, P >0.05), while significant differences were seen in the qualification rate of blood smears preparation, dyeing and cleanliness each year from 2011 to 2018 (all P values < 0.05). Conclusions The quality of malaria blood smears is high in all districts of Zibo City; however, the quality of city-level blood smears remains to be improved. Further actions to improve the training of grassroots microscopic examinations and quality control of malaria blood smears are required to ensure the capability of microscopic examinations of Plasmodium during the malaria post-elimination stage.
