ABSTRACT

Objective To investigate the awareness of malaria-related knowledge, the use of mosquito nets and their influencing factors among residents in Banlao Township, Cangyuan County, Yunnan Province.. Methods In August 2020, 19 settlement sites in Banlao Township, Cangyuan County, Lincang City, Yunnan Province were selected as study areas, and permanent residents at ages of 10 years and older were enrolled for a questionnaire survey, including residents’ demographics, family economic status, malaria control knowledge and use of mosquito nets. In addition, the factors affecting the use of mosquito nets in the night prior to the survey were identified using multivariate logistic regression analysis. Results A total of 320 questionnaires were allocated, and all were recovered (a 100% recovery rate). There were 316 valid questionnaires, with an effective recovery rate of 98.75%. The 316 respondents included 152 men and 164 women and 250 Chinese respondents and 66 foreign respondents. The awareness of clinical syndromes of malaria was significantly higher among Chinese residents (71.60%) than among foreign residents (50.00%) (χ2 = 11.03, P < 0.01), and the proportions of Chinese and foreign residents sleeping under mosquito nets were 46.00% and 69.70% on the night prior to the survey, respectively (χ2 = 11.73, P < 0.01). Multivariate logistic regression analysis identified ethnicity group and type of residence as factors affecting the use of mosquito nets in the night prior to the survey. Conclusions The awareness of malaria control knowledge, the coverage and the use of mosquito nets were low among residents in Banlao Township, Cangyuan County, Yunnan Province. Targeted health education is recommended to improve the awareness of malaria control knowledge and self-protection ability. In addition, improving the allocation of long-lasting mosquito nets and health education pertaining to their uses and increasing the proportion of using mosquito nets correctly is needed to prevent re-establishment of imported malaria.

ABSTRACT

OBJECTIVE To compare the efficacy, safety and economics of bid-winning and original Moxifloxacin hydrochloride tablets in the treatment of outpatient community-acquired pneumonia (CAP). METHODS A retrospective cohort study was conducted to screen and include CAP outpatients during the period of January to December 2021 in Lianyungang First People’s Hospital. They were divided into generic drug group (1 058 cases) and bid-winning drug group (1 121 cases) according to the drug source. Two groups were respectively given original and bid-winning Moxifloxacin hydrochloride tablets, 0.4 g each time, once a day. The efficacy indexes (clinical effective rate, remission time, treatment course, revisiting rate) and safety indexes (allergy, nervous system symptoms, etc.) were compared between the two groups; and the influence factors of clinical treatment failure were analyzed with multi-factor modified Poisson regression model. The economic indicators of the two drugs [quantity, consumption sum, defined daily doses (DDDs), defined daily dose cost (DDDc), price ratio, replacement rate] were compared. RESULTS There were no significant differences in the clinical effective rate, treatment course, revisiting rate, the incidence of nervous system symptoms and Q-T interval prolongation between the two groups (P>0.05). The remission time of original drug group was significantly shorter than that of bid-winning drug group, and the incidence of total adverse drug reaction, allergy reaction, gastrointestinal symptom reaction and hyperglycemia were significantly lower than those in bid-winning drug group(P<0.05). Multivariate Poisson regression analysis showed that bid-winning drug did not increase the risk of clinical treatment failure in CAP outpatients [RR=1.132, 95%CI (0.883, 1.542), P=0.327]. However, antibiotic exposure history, more than 2 items of abnormal clinical manifestations and auxiliary examination all increased the risk of clinical treatment failure (P<0.05). Compared with before the implementation of centralized volume-based procurement policy, the quantity and DDDs of Moxifloxacin hydrochloride tablets increased significantly, while the consumption sum decreased significantly, DDDc of bid-winning drug decreased significantly, the price ratio of it to original drug decreased to 0.117, and the replacement rate increased to 69.44% after the implementation of centralized volume- based procurement policy. CONCLUSIONS Compared with original drug, bid-winning Moxifloxacin hydrochloride tablet shows reliable efficacy and obvious price advantage in the treatment of outpatient CAP, but the incidence of adverse drug reactions is higher.

ABSTRACT

Objective:To discuss strategies in treatment of poorly differentiated thyroid carcinoma (PDTC) .Methods:Clinical data of 31 cases with PDTC were reviewed retrospectively, who were treated in Department of Head & Neck Surgery, Sichuan Cancer Hospital & Institute by primary surgical resection with or without adjuvant therapy. 27 cases had total thyroidectomy compounded neck dissection or extened total thyroidectomy when trachea or esophagus involved. 4 cases underwent partial resection of tumor. 11 cases were treated with external beam radiotherapy (EBRT) after surgery, 10 cases were treated with postoperative radioiodine, and 8 cases had chemotherapy.Results:The median follow-up time was 18 months (ranged from 3-96 months) . 19 patients died of local recurrence or distant metastasis. Kaplan-Meier analysis and Log-rank analysis was used to compare the differences between groups. Five-year survival was 35.9%. Compared to the cases with partial resection, the cases with surgical disease clearance had longer survival ( P=0.00) . The same statistical difference was found between patients with or without radioiodine ( P=0.017) . The patients treated with radioiodine had longer survival. No statistical differences were found among patients with or without chemotherapy or EBRT. COX regression analysis showed stage of tumor ( P=0.005) , total resection ( P=0.006) and postoperative radioiodine ( P=0.013) were same to predict longer survival. Conclusions:Thorough resection of tumor is the most important therapy for PDTC. Postoperative radioiodine is recommended for patients with high recurrence risk. EBRT is recommended to control local unresectable PDTC.

ABSTRACT

Objective:To investigate the effects and the mechanism of renal protection of curcumin on oxidative stress and lipid metabolism in diabetic rats.Methods:60 Wistar rats were randomly divided into normal control group ( n=20) and diabetic model preparation group ( n=40). Rats in the normal control group were fed with normal diet, while rats in the diabetes model group were fed with high sugar and high fat diet. After 4 weeks of feeding, rats in the diabetic model preparation group were injected with streptozotocin (60 mg/kg) intraperitoneally once. A total of 35 rats were successfully modeled and then randomly divided into diabetic model group ( n=17) and curcumin group ( n=18). The diabetic model group continued to be fed with high sugar and high fat diet, and the curcumin group was given high sugar and high fat diet and 200 mg/(kg·d) curcumin (1% carboxymethyl fiber sodium prepared into suspension) intervention every day; while the normal control group and the diabetic model group were given 1% carboxymethyl fiber sodium of the same volume. The body weight, kidney index, blood glucose , serum creatinine, urea nitrogen, blood lipid and 24-hour urinary microalbumin excretion rate (24 h UAER) of rats in each group were measured. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and m-alondialdehyde (MDA) in serum and kidney tissues were measured. Results:Compared with the control group, the levels of the body weight, kidney index, blood glucose, serum creatinine, urea nitrogen, triglyceride, total cholesterol and 24 h UAER in the diabetic model group increased significantly. The level of MDA in serum and kidney tissues increased significantly ( P<0.05), while the levels of SOD, CAT and GSH-Px activities in serum and kidney tissues decreased significantly ( P<0.05). Compared with diabetic model group, the levels of the body weight increased, while the kidney index, blood glucose, serum creatinine, urea nitrogen , triglyceride, total cholesterol and 24 h UAER in the curcumin group decreased significantly, the level of MDA in serum and kidney tissues decreased significantly ( P<0.05); the levels of SOD, CAT and GSH-Px in serum and kidney tissues increased significantly ( P<0.05) in the curcumin group. Conclusions:Curcumin may play a renal protective role in diabetic rats by inhibiting oxidative stress in serum and kidney and reducing blood lipid.

ABSTRACT

High mobility group protein B1 (HMGB1) is a kind of nuclear protein widely existing in cells, which is released or secreted from cells by stress in the body and plays a key role in the survival or death pathways of cells. HMGB1 has a huge biological function and is the main regulator of major diseases such as inflammatory diseases and tumors. HMGB1 is closely related to the proliferation, differentiation, migration, apoptosis and drug resistance of tumor cells. With the continuous deepening of research on HMGB1, it is found that HMGB1 plays an important role in the occurrence, development, metastasis and drug resistance of breast cancer. Combined with the research status of HMGB1, the expression of HMGB1 in breast cancer is discussed to provide a new therapeutic scheme for clinical treatment.

ABSTRACT

Objective@#To explore the advantages and clinical efficacy of free chimeric perforator flap based on the descending branch of circumflex femoral artery applied to tongue reconstruction after advanced tongue cancer resection.@*Methods@#From October 2013 to December 2018, 57 cases received tongue and oral base reconstruction surgeries using the descending branch of circumflex femoral artery chimeric perforator flap, including 39 males and 18 females, ranged from 20 to 76 years old. And all cases were with stage T3 and T4 tongue cancers, including 35 cases of squamous cell carcinoma, 7 cases of low differentiation cancer, 5 cases of oncosarcoma, and 10 cases of adenoid cystic carcinoma. The tongue was reconstructed by using perforator flap and muscle flap to fill the dead space at the oral floor. The artery anastomoses with the superior thyroid artery or facial artery in the receiving area, and the vein anastomoses with the internal jugular vein in the receiving area. The shape, function and local complications of the reconstructed tongue were observed after operation.@*Results@#Of 57 cases, only one case had partial necrosis of flap, while other 56 cases with chimeric perforator flap survived. Postoperative gastric tube and tracheal cannula were removed in all patients, no cases with oral fistula. All donor sites were sutured in one stage. Postoperative radiotherapy was performed in 41 of the patients. All patients were followed up for 3 to 60 months (average of 20.7 months), with satisfactory esthetic and functional results in reconstructed tongues. Only linear scars were left in the donor areas of the legs, and no lower limb dysfunction was observed.@*Conclusions@#The descending branch of circumflex femoral artery chimeric perforator flap can used for repairing simultaneously the defects of both tongue and oral base. It is helpful to avoid the occurrence of oral fistula and to provide the reconstructed tongue with a good function. It is a good choice to use the descending branch of circumflex femoral artery chimeric perforator flap for tongue reconstruction after resection of advanced tongue cancer resection.

ABSTRACT

OBJECTIVE: To optimize the water extraction technology of classic formula Taohe chengqi decoction. METHODS: Based on single factor test, combined with response surface methodology and information entropy theory, the soaking time, solid-liquid ratio and extraction time were investigated. Using the contents of rhein, amygdalin, cinnamaldehyde and glycyrrhizic acid in Taohe chengqi decoction as indexes, information entropy theory was used to assign weight coefficients to each evaluation index and calculate the comprehensive score. Through Design-Expert 10 software, the interactions of each factor were analyzed. Water extraction technology was optimized, and validation test was also performed. RESULTS: According to information entropy theory, the weight coefficients of rhein, amygdalin, glycyrrhizic acid and cinnamaldehyde were located at 0.097 6, 0.363 2, 0.173 5 and 0.365 7. The results of interaction analysis showed that the material-liquid ratio had a greater impact on the comprehensive score. The optimal water extraction technology of Taohe chengqi decoction were determined as that soaking time was 60 min; the ratio of material to liquid was 1 ∶ 10 (g/mL); total extraction time was 130 min (extracting for 3 times, lasting for 65, 33, 32 min each time). The results of verification test showed that RSD of content of each index component and the comprehensive score was less than 3%. CONCLUSIONS: The optimal water extraction technology is proved to be stable and feasible, which can provide the basis for the further development and utilization of Taohe chengqi decoction.

Objective To compare the efficacy of the solid tumor evaluation criteria 1.1 (RECIST 1.1) and the revised solid tumor efficacy evaluation criteria (mRECIST) after chemotherapy in the hepatocellular carcinoma system.Methord Retrospective analysis of 34 patients with advanced hepatocellular carcinoma who underwent Folfox4 system chemotherapy from the Department of Hepatobiliary and Pancreatic Surgery of Dongfeng Hospital affiliated to Hubei Medical College from July 2017 to July 2018,including 24 males and 10 females.Spiral CT and/or MRI (four-phase) scans were performed 1 nonth,2 months,and every 2 months after treatment,and the effects were evaluated by RECIST 1.1 and mRECIST,respectively.The survival curve was drawn by Kaplan-Meier method,and log-rank test was used to compare survival curves.Result In 34 patients evaluated with the RECIST 1.1 criteria,0 patient showed complete remission (CR),6 patients partial remission (PR),20 patients stable disease (SD),and 8 patients progressive disease (PD).Using the mRECIST criteria,CR:0,PR:10,SD:17,and PD:7 patients.The Kappa value of the two methods was 0.271,95% CI:0.010 ~0.535.The log-rank test showed that there was no significant difference in the survival curves of patients between PR,SD and PD in RECIST 1.1 (P > 0.05).The cumulative survival rates were 40.0%,11.8% and 0,respectively.The survival curves of patients with PR,SD and PD in mRECIST were statistically significant (P < 0.05),and the cumulative survival rates were 37.5%,0,and 0,respectively.Conclusion The mRECIST criteria were more suitable than the RECIST 1.1 criteria in assessing efficacy of systemic chemotherapy for hepatocellular carcinoma.

ABSTRACT

Objective To investigate ultrasonographic features of different pathological types of mucinous breast carcinomas (MBC), and to improve the diagnosis rate of MBC. Methods The ultrasonographic features of 42 MBC cases between January 2014 and December 2015 in Shanxi Provincial Cancer Hospital were retrospectively analyzed according to pathological types. Results There were 24 cases of simple type and 18 cases of mixed type in 42 MBC cases (46 lesions in total). The coincidence rate of preoperative ultrasound diagnosis for cancerous lesions was 93.5 % (43/46), including 24 cases of 27 simple type lesions with oval form or lobulated (20/27, 74.1 %), clear boundary (21/27, 77.8 %), uniform internal echo (17/27, 63.0 %), posterior echo enhancement (11/27, 40.7 %), and 18 cases of 19 mixed type lesions with irregular shape (14/19, 73.7 %), unclear border (16/19, 84.2 %), uneven internal echo (13/19, 68.4 %), posterior echo attenuation (13/19, 68.4 %). The differences between the two types of ultrasound images were statistically significant (both P<0.05). Of 42 cases, 76 axillary lymph nodes were transferred in 13 cases. Preoperative ultrasonography showed that 32 axillary lymph nodes enlargement were abnormal in 12 cases, and the detection rate was 42.1 % (32/76). The positive rates of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) were 87.5 % (21/24), 79.2 % (19/24), 8.3 % (2/24) in simple type and 83.3 % (15/18), 88.9 % (16/18), 5.6 % (1/18) in mixed type respectively. There was no significant difference in the positive rates of 3 kinds of molecular markers among two types (all P>0.05). Conclusions Due to the different tissue components in different types of MBC, ultrasonic features show several differences. Simple type is similar to benign masses, while mixed type shows the characteristics of invasive carcinomas.

ABSTRACT

OBJECTIVE: To provide scientific evidence for the further improvement of hospital antibacterial management, the formulation of related management decisions and long-acting mechanism. METHODS: Technique for order preference by similarity to ideal solution (TOPSIS) was used to select 8 evaluation indexes as utilization rate of antibiotics in the inpatients to synthetically evaluate the effect of antibacterial management in 10 third grade general hospitals of Xi'an from 2012 to 2016. RESULTS: Results of synthesis evaluation by TOPSIS method showed that the least effect was in 2012 [coefficient of proximity from the object of evaluation to the optimal value (Ci) =0]; the effect of antibacterials management was improved gradually during 2013-2015, and there was the best effect in 2015 (Ci=0. 918 3); but declined in 2016 (Ci=0. 838 5). Only one evaluation index (the rate of microbial examination in the inpatient receiving special use of antibacterials) was improved significantly in the 5 years(P<0. 01), but there was no statistical significance in the data of other 7 indexes (P>0. 01). CONCLUSIONS: The effect of antibacterials management in 10 third grade general hospitals of Xi'an was on the rise from 2012 to 2015, but was declined in 2016. It might be slack. A long-acting management mechanism of antibacterial management is needed to be established, in order to consolidate the achievements from "special rectification for clinical antibacterial use" and further improve the normal and dynamic operation of antibacterial management measure. TOPSIS method is objective and comprehensive method for synthesis evaluation of the effect of antibacterial management, and is of significance to antibacterial supervision and use.
