OBJECTIVE:To improve the quality of ADR reports. METHODS:By using intensive hospital monitoring mode, ADR reports before and after the application of the system would be collected and factors as report quantity,type,time and quality of reports were analyzed statistically. RESULTS:It provided rapid reporting function after the implementotion of the system. Total quantity of reported ADR cases increased from 589 to 748,and the proportion of all the serious ADR reports increased from 62.8%to 11.76%. The score of repert quality increased from 93.64 to 98.36,the proportion of time-out reports increased from 94.05% to 97.33%,with statistical significance (P<0.05). CONCLUSIONS:Rapid reporting system of ADR in the hospital is beneficial to improve the efficiency and guarantee the quality of the reports. It also can expand the coverage of the monitoring network,and can lay the foundation for drug safety scientific evaluation and monitoring.

Objective:To retrospective analyze the epidemiology, clinical characteristics, treatment and prognosis in patients with coronavirus disease 2019 (COVID-19).Methods:A total of 278 patients with COVID-19 admitted to Guangzhou Eighth People′s Hospital from January 20 to February 10, 2020 were selected. The general demographic data, epidemiological data, clinical symptoms, laboratory examinations, lung CT imaging, treatment and prognosis were analyzed.Results:There were 130 male patients (46.8%) and 148 females (53.2%) with age (48.1±17.0) years and 88.8% patients between 20-69 years. Two hundred and thirty-six (84.9%) patients had comorbidities. Two hundred and eleven cases (75.9%) were common type. The in-hospital mortality was 0.4% (1/278). The majority (201, 72.3%) were imported cases mainly from Wuhan (89, 44.3%). The most common clinical manifestations were fever (70.9%) and dry cough (61.5%). In some patients, hemoglobin (10.4%), platelets (12.6%) and albumin (55.4%) were lower than the normal range. Other biochemical tests according to liver and function were normal, while lactic dehydrogenase (LDH) was elevated in 61 patients (21.9%), creatine kinase increased in 26 patients (9.4%). Prolonged activated partial thromboplastin time (APTT) was seen in 52 patients (18.7%), D-dimer higher than normal in 140 patients (50.4%), while 117 patients (42.1%) had elevated high-sensitivity C-reactive protein. Typical CT manifestations included single or multiple ground glass shadows especially in lung periphery in early disease which infiltrated and enlarged during progressive stage. Diffuse consolidation with multiple patchy density in severe/critical cases and even "white lung" presented in a few patients. Two hundred and forty-two patients (87.1%) received one or more antiviral agents, 242 (87.1%) combined with antibacterials, 191 (68.7%) with oxygen therapy. There were 198 patients (71.2%) treated with traditional Chinese medicine.Conclusions:COVID-19 could attack patients in all ages with majority of common type and low mortality rate. Clinical manifestations involve multiple organs or systems. Progression of the disease results in critical status which should be paid much attention.

s] Objective To evaluate the effect of comprehensive schistosomiasis control measures with focus on total removal of cattle and sheep in Junshan District,Yueyang City. Methods The retrospective review and field survey were implemented in the pilot villages in Junshan District. The data of Schistosoma japonicum infection status of human,cattle,sheep and Oncome-lania hupensis snails,and density of snails were gathered and modeled in the period of 2006 to 2016. Results The prevalence of schistosome infection in residents in the pilot villages decreased from 3.44％ in 2006 to 0.59％ in 2012(F = 14.501,P =0.013). After removal of all the cattle and sheep in 2013,the prevalence of schistosome infection in the residents decreased to zero in 2016(F=14.148,P=0.033). The density of living snails decreased from 0.8833/0.1 m2 in 2006 to 0.3088/0.1 m2 in 2012(F=76.250,P=0.005). Conclusion The comprehensive schistosomiasis control strategy with focus on cattle and sheep removal is remarkably effective.

Objective:To explore the relationship between death indicators and unplanned return indicators on healthcare quality evaluation.Methods:A total of 836 976 medical record data were collected from 31 tertiary public general hospitals in a diagnosis-related groups(DRG) data platform in 2017. Multiple death indices(low and low-risk risk group mortality, high-risk group mortality, crude mortality, and risk adjusted mortality) and unplanned return indices(31-day unplanned readmission rate and 31-day unplanned return to surgery rate) were calculated. Pearson′s correlation coefficient was used to examine the relationships among those indices.Results:Death indicators were correlated with each other, but the unplanned readmission rate was not correlated with the unplanned reoperation rate( r=0.305). There was no correlation between unplanned re-entry rate and death rate. The correlation coefficients were as follows: unplanned readmission rate versus low and low-risk group mortality( r=-0.227), versus high-risk group mortality( r=-0.098), versus actual mortality( r=-0.130), versus risk adjusted mortality( r=0.010); unplanned reoperation rate versus low and low-risk group mortality( r=0.105), versus high-risk group mortality( r=0.030), versus actual mortality( r=-0.004), versus risk adjusted mortality( r=-0.141). Conclusions:The indicators of death and the indicators of unplanned return are not the same in terms of actual management technology and evaluation effect. They are complementary to each other and can form an ideal combination of quality evaluation indicators.

Objective:To explore the influencing factors of 31-day unplanned readmission in obstetrics.Methods:The medical records and relevant clinical data of 29 public hospitals in a province in 2017 were collected to construct a two-level logistic regression model on the influencing factors of 31-day unplanned readmission.Results:In 2017, there were 71 330 obstetric patients discharged from 29 public hospitals, 690 of whom were unplanned readmitted in 31 days, accounting for 0.97%. The type of medical insurance payment, number of previous hospitalization, condition of previous hospitalization, age, history of cesarean section, pregnancy complications and complications during delivery were all the factors influencing the 31-day unplanned readmission of obstetrics.Conclusions:The condition of 31-day unplanned readmission could be influenced by the factors of sociology, previous visit and clinical. These factors should be considered reasonably in the evaluation and management of obstetric quality.

Objective:To investigate the effect of ultrasound-guided lumbar quadratus muscle plane block combined with general anesthesia on the analgesic effect during and after laparoscopic colon cancer radical surgery in elderly patients.Methods:A prospective study was conducted on 61 elderly patients who underwent radical colon cancer surgery at the Changsha Central Hospital Affiliated to South China University from May 2022 to February 2023, with American Society of Anesthesiologist (ASA) grades Ⅱ to Ⅲ. They were randomly divided into SA and GA groups using a random number table method, with 31 patients in the SA group and 30 patients in the GA group. The SA group received ultrasound-guided plane block of the upper lumbar quadratus muscle in the arcuate ligament combined with general anesthesia, while the GA group received simple general anesthesia. Record the mean artery pressure (MAP) and heart rate (HR) of two groups of patients at the time of entering the operating room (T 0), 5 minutes before skin incision (T 1), at skin incision (T 2), 30 minutes after surgery (T 3), at surgery end (T 4), and during anesthesia resuscitation and extubation (T 5); The Visual Analogue Scale (VAS) of two groups of patients at T 5, upon returning to the ward (T 6), 6 hours (T 7), 12 hours (T 8), 24 hours (T 9), and 48 hours (T 10) after surgery were recorded; The dosage of sufentanil, remifentanil, and propofol used during surgery, anesthesia recovery time, total number of analgesic pump presses within 48 hours after surgery, Lovett muscle strength score, early postoperative recovery, and adverse reactions within 48 hours after surgery were also recorded. Resultsl:The MAP and HR of the SA group were lower than those of the GA group at T 1-5 (all P<0.05); The VAS score of the SA group was lower than that of the GA group at T 5-10 (all P<0.05); The intraoperative dosage of propofol, remifentanil, and sufentanil in the SA group was lower than that in the GA group (all P<0.05); The anesthesia recovery time and first time out of bed in the SA group were earlier than those in the GA group (all P<0.05); The total number of times the analgesic pump was pressed within 48 hours after surgery was less than that of the GA group ( P<0.05); The incidence of nausea and vomiting within 48 hours after surgery in the SA group was lower than that in the GA group ( P<0.05). There was no statistically significant difference in postoperative Lovett muscle strength score, hospital stay, and dizziness incidence between the two groups of patients (all P>0.05). Conclusions:Ultrasound-guided lumbar quadratus muscle plane block on the arcuate ligament can significantly reduce the dosage of intraoperative general anesthesia drugs and postoperative analgesics in elderly patients undergoing laparoscopic colon cancer surgery, reduce postoperative pain scores, effectively alleviate postoperative pain, and thus advance the patient′s first time out of bed activity, reduce postoperative complications, and promote rapid recovery.

Objective: To analyze the significance of serum free light chain (sFLC) for the prognosis of the patients with newly diagnosed multiple myeloma (NDMM). Methods: The clinical data of 621 NDMM patients in Changzheng Hospital from June 2010 to December 2016 was retrospectively analyzed. The serum free light chain levels were measured and the ratios of κ/λ chains were calculated. The significance of serum free light chain ratio (sFLCR) for the prognosis of NDMM patients was analyzed. Results: Among the 621 NDMM patients, 42 patients (6.8%) were in the normal free light chain ratio group (0.26≤sFLCR≤1.65), 247 patients (39.8%) were in the low free light chain ratio group (0.01＜sFLCR＜0.26 or 1.65＜sFLCR＜100), and 332 patients (53.5%) were in the high free light chain ratio group (sFLCR≤0.01 or sFLCR≥100). Compared with normal sFLCR group, the abnormal sFLCR group showed low level of hemoglobin; elevated levels of bone marrow plasma cells, serum creatinine and β 2 -MG, and more patients were in DS stage Ⅲ and ISS stage Ⅲ with high risks of cytogenetics(all P＜0.05). The overall survival (OS) in the normal sFLCR group was significantly better than the abnormol sFLCR groups (not reached vs 58.7 months, P=0.043). Compared with the patients with both high sFLCR and low risks of cytogenetics, the patients with high sFLCR and high risks of cytogenetics showed shorter overall survival time (median OS time was 41.6 months vs 61.4 months, P=0.015). Conclusion The NDMM patients with significantly abnormal sFLCR may indicate more tumor load and higher aggressive progression. sFLCR should be an independent prognostic indicator for the outcome of multiple myeloma. The patients with high sFLCR and cytogenetic abnormalities, have worse prognosis than the others.
