ABSTRACT

Objective@#To investigate the recurrence of pulmonary tuberculosis patients 5 years after successful treatment in Hengyang City, Hunan Province, and to analyze its influencing factors.@*Methods@#The data of pulmonary tuberculosis patients who were successfully treated in Hengyang City in 2014 were collected through the tuberculosis management information system. The recurrence of pulmonary tuberculosis was defined as the endpoint, and all patients were observed for five consecutive years. Factors affecting recurrence of pulmonary tuberculosis were identified using Kaplan-Meier estimates, log-rank test and multivariable Cox proportional hazards regression analysis.@*Results@#A total of 6 626 patients with successfully treated pulmonary tuberculosis were included, including 4 961 males and 1 665 females, with a median age of 54 years. There were 536 cases with recurrence of pulmonary tuberculosis within five years, with a 8.09% cumulative proportion of recurrence and annual recurrence rate of 1.75 per 100 person-years. Multivariable Cox proportional hazards regression analysis showed that men ( HR=1.592, 95%CI: 1.256-2.019 ), age of 40 years and greater ( age of 40 to 59 years, HR=7.025, 95%CI: 1.739-28.377; age of 60 years and greater, HR=8.175, 95%CI: 2.024-33.023), farmers ( HR=1.379, 95%CI: 1.070-1.778 ), retreatment ( HR=6.398, 95%CI: 5.163-7.929 ) and positive etiology ( HR=1.255, 95%CI: 1.042-1.511 ) were risk factors for five-year recurrence of pulmonary tuberculosis among successfully-treated patients.@*Conclusions@#High recurrence rate is found among pulmonary tuberculosis patients within five years after successful treatment in Hengyang City. There is a high risk of pulmonary tuberculosis recurrence among male, etiologically positive, retreated farmers at ages of 40 years and older, and targeted interventions are recommended.

ABSTRACT

Objective: To observe the clinical efficacy of pediatric massage (tuina) for chronic cough in children. Methods: A total of 96 cases were randomized into a control group and an observation group, with 48 cases in each group. Cases in the control group received routine pediatric massage manipulations. Cases in the observation group received additional Mo-rubbing abdomen manipulation. The treatment was done 3 times a week and 12 times made up a treatment session. The cough symptom scores were evaluated before treatment and after 3, 6, 9 and 12 treatments respectively. Results: There were 8 dropouts in the observation group and 5 dropouts in the control group. Before treatment, there was no statistical difference in coughing score between the two groups (P>0.05). After 9 times of treatment, the total coughing scores were significantly reduced in both groups (both P<0.05); however, there were no statistical differences between the two groups in the score differences between before treatment and after 3, 6 and 9 times of treatment (all P>0.05). After 12 times of treatment, the total coughing scores were significantly reduced in both groups (both P<0.05), along with a statistical difference between the two groups in the score difference between before treatment and after 12 times of treatment (P<0.05). There was a statistical difference between the two groups in overall response (P<0.05). The total effective rate in the observation group was 92.5%, versus 86.0% in the control group, showing a statistical difference (P<0.05). Conclusion: The routine pediatric massage manipulations alone or in combination with Mo-rubbing abdomen manipulation both can significantly improve chronic cough in children; however, the combination obtains a better effect.

ABSTRACT

Objective:To investigate the method and application experience of nasolabial subcutaneous pedicled flap in the repair of skin defect after resection of nasolabial mass.Methods:From December 2016 to December 2020, a total of 58 patients (43 cases of nevus, 12 cases of seborrheic keratosis and 3 cases of keratinacanthoma) were admitted to the Facial Neck Center of Plastic Surgery Hospital of Chinese Academy of Medical Sciences, including 24 males and 34 females. They ranged from 17 to 55 years old, with an average age of 33 years. The minimum facial tumor area was 0.8 cm×0.8 cmand the maximum was 2.2 cm×2.0 cm. A local skin flap with a subcutaneous pedicle was designed preoperatively in the nasolabial groove area, and the subcutaneous pedicle was transferred to the defect area through subcutaneous tunnel or by disconnecting the surrounding tissue. The tumor was removed and the skin defect was closed at one stage. Postoperative complications were summarized and patient's satisfaction was investigated.Results:Follow-up period ranged from 6 to 48 months. All the 58 patients had primary healing of the transfer incisions, and all the flaps survived. The blood supply of the flaps was good, and the scar of the operative area was smooth. After resection of peri-lip mass, there was 1 case with obvious scar in the donor area of nasolabial groove, and the overall satisfaction rate was 98.3%.Conclusions:The application of nasolabial subcutaneous pedicled skin flap to repair the skin defect after resection of nasolabial tumor has the advantages of preventing the pulling deformation of the organ, it can be completed in one stage and repair the facial skin defect from a distant position. In addition, the thickness and color of the skin flap are similar to the defect site, and the scar of the donor site is not obvious, and so the appearance and function of the surgery can be satisfied.

ABSTRACT

Objective:To survey the status quo of job burnout among rural general practitioners and to analyze its influencing factors.Methods:A total of 2 805 rural general practitioners in three counties in southwest Shandong province were enrolled in the study. The survey was conducted with a basic information questionnaire and the Maslach Burnout Inventory-Human Service Survey (MBI-HSS). The influencing factors of job burnout were analyzed by Pearson chi-square test (χ2) and binary logistic regression model.Results:A total of 2 272 rural general practitioners completed the survey with a completion rate of 81.0%. The rates of middle or high job burnout in the dimensions of emotional exhaustion, depersonalization and reduced personal sense of achievement were 55.1%(1 251/2 272), 34.0%(772/2 272) and 91.3%(2 075/2 272), respectively. Binary logistic regression model showed that working hours/week ≥ 60 h ( OR=1.341, 95 %CI:1.057-1.702, P<0.05), monthly shift times ≥20 ( OR=1.434, 95 %CI:1.182-1.739, P<0.05), daily consultation time≥13 h ( OR=1.294, 95 %CI:1.055-1.589, P<0.05), daily consultation of 11-20 patients ( OR=1.317, 95 %CI:1.075-1.614, P<0.05), no part-time job ( OR=1.583, 95 %CI:1.201-2.087, P<0.05), insomnia ( OR=2.638, 95 %CI:2.225-3.128, P<0.05), feeling depressed at work ( OR=3.170, 95 %CI:2.661-3.776, P<0.05) were risk factors for emotional exhaustion; participation in public health services ( OR=1.485, 95 %CI:1.155-1.910, P<0.05), being married ( OR=2.273, 95 %CI:1.198-4.313), no part-time jobs ( OR=1.677, 95 %CI:1.276-2.203, P<0.05), insomnia ( OR=1.487, 95 %CI:1.211-1.827, P<0.05), and feeling depressed at work ( OR=1.642, 95 %CI:1.339-2.015, P<0.05) were risk factors for depersonalization; working hours/week ≥ 60 h ( OR=2.089, 95 %CI:1.454-3.002, P<0.05), daily consultation time ≥ 9 h ( OR=2.495, 95 %CI:1.748-3.561, P<0.05), insomnia ( OR=2.061, 95 %CI:1.519-2.796, P<0.05), and feeling depressed at work ( OR=1.894, 95 %CI:1.383-2.593, P<0.05) were risk factors for reduced personal achievement. Protective factors included monthly income ≥3 000 Yuan ( OR=0.589, 95 %CI: 0.353-0.982, P<0.05) and monthly shift of 10-19 times ( OR=0.581, 95 %CI:0.411-0.820, P<0.05). Conclusion:The overall job burnout among rural general practitioners in southwest Shandong province is serious, especially the depersonalization and the reduction of personal sense of achievement. It is suggested to improve the salary, reduce the working intensity, optimize the working hours, and pay attention to their physical and mental health for rural general practitioners to alleviate the current situation of their occupational burnout.

ABSTRACT

Objective::Astragali Radix is an important medicinal and edible herb. To achieve standardized cultivation of Astragali Radix and improve cultivation results, Astragalus membranaceus var. mongholicus was cultivated with a row spacing of 30 cm and different plant spacing (8, 10, 12, 14, 16 cm) in a test base of Longxi County, Gansu Province. Method::The growth and development dynamics of green strains and the yield and quality of medicinal materials were measured, and the comprehensive evaluation of membership function was used to determine the rational transplanting density and explore the standard production technology of A. membranaceus var. mongholicus. Result::The transplanting topping had a significant effect on the growth and development of A. membranaceus var. mongholicus under the condition of the row spacing of 30 cm. With the increase of topping, the biomass of astragalus on the ground decreased, and the ratio of root to shoot increased, but the yield of medicinal material per unit area decreased. The appearance traits were improved as the transplant density decreased. Under the row spacing of 14 cm, the content of astragaloside and calycosin-7-glucoside were the highest. Under the row spacing of 8-16 cm, the content of root extract of Astragali Radix was better than the Chinese Pharmacopoeia standard. The comprehensive evaluation index of each plant spacing treatment was 14 cm>16 cm>10 cm>8 cm>12 cm in turn. Conclusion::Combined with the comprehensive evaluation of yield and economic benefit, the optimal transplanting plant spacing and row spacing were 30 cm×14 cm (with the density of 238 100 strains/hm2). Under this density, A. membranaceus var. mongholicus grows vigorously, with thick stems, big root crowns, a high yield and high quality.

ABSTRACT

Objective:To compare ultrasound (US) guided versus computed tomography (CT) guided radiofrequency ablation (RFA) in treatment of early hepatocellular carcinoma (HCC).Methods:The data of 133 patients with early HCC treated by RFA in the Department of Hepatobiliary Surgery of Shandong Provincial Hospital from February 1, 2015, to January 31, 2017, was analyzed retrospectively. These patients were divided into two groups: the US-guided group and the CT-guided group. The clinical data was collected and the factors affecting prognosis were analyzed.Results:Compared with the CT-guided group, the operation time of the US-guided group was significantly shorter [(29.0±12.0)min vs. (55.0±19.0)min, P<0.05], but the number of ablation sessions per tumor was significantly less [(1.1±0.3) vs. (2.0±0.6), P<0.05]. There was no significant difference in the complete ablation rates, postoperative complication rates and postoperative length of hospital stay between the two groups ( P>0.05). The CT-guided group was superior to the US-guided group in the local tumor recurrence and progression-free survival rates ( P<0.05). On multivariate analysis, CT-guided RFA was an independent protective factor for local tumor recurrence ( HR=0.266, 95% CI: 0.073-0.967, P<0.05) and progression-free survival ( HR=0.415. 95% CI: 0.213-0.806, P<0.05), while AFP >20 ng/ml ( HR=4.821, 95% CI: 1.714-13.560, P<0.05) was an independent risk factor for progression-free survival. Conclusion:CT-guided percutaneous RFA was superior to US-guided RFA in local treatment of early HCC, probably related to more needle placements and longer ablation time under CT guidance.

ABSTRACT

This study aimed to clarify the microbial diversity, dominant species and the change of community structures in the fermentation of Liushenqu(Massa Medicata Fermentata), and explore the material foundation of its pharmacodynamics effect. On the basis of standardizing the fermentation process, Massa Medicata Fermentata was prepared by screening and optimizing the recipes and the standard formula issued by the Ministry. The community structure and growth process of fungi and bacteria in the samples at five time points(0, 17, 41, 48, 65 h) in the fermentation process of Massa Medicata Fermentata were analyzed by using isolation and culture of eight different media and high-throughput DNA sequencing technology. The results indicated that the samples of the two recipes pre-sented high microbial diversity at the initial fermentation stage, with Aspergillus spp. as the dominant species. As the fermentation process goes forward, Saccharomycopsis fibuligera and Rhizopus oryzae soon became dominant species from 17 h after fermentation commencement point to the fermentation end, while the other species were inhibited at a lower level from 17 h. The species diversity of bacteria in the initial fermentation samples was also high, and Enterobacter was the dominant species. Enterobacter cloacae, Pediococcus pentosaceus and Cronobacter sakazakii became dominant bacterial species 17 h after fermentation commencement, while the species diversity was decreased. Our results will be a scientific basis for promoting the fermentation process of Massa Medicata Fermentata by using pure microbial cultures.

ABSTRACT

The aim of the present study was to investigate the effect of Sophoral flavones on proliferation of cardiac fibroblasts (CFb) induced by high glucose and its underlying mechanism. Cardiac fibroblasts were exposed to different concentration of D-glucose (15, 25 and 35 mmol·L-1) at different time point (24, 48 and 72 h) in order to determine cell proliferation, and the model group was established by culturing CFb with 25 mmol·L-1D-glucose for 48 h. Sophoral flavones (12.5, 25 and 50 mg·L-1) were employed for intervention. The cell viability was measured by MTT assay, and the levels of transforming growth factor-β1 (TGF-β1), matrix metalloproteinase-2 (MMP-2), collagen Ⅰ and collagen Ⅲ were measured by ELISA. In addition, flow cytometry was employed to detect the cell cycle; while the protein expression of prohibitin (PHB) was observed via immunocytochemistry and Western blot. This animal experiment had been approved by Jilin Medical University Experiment Animal Ethics Review Committee. The results showed that 25 mmol·L-1 glucose could promote the proliferation of CFb; and the contents of TGF-β1, MMP-2, collagen Ⅰ and collagen Ⅲ in the model group were higher than that of control (P<0.05). The number of cells in S and G2 phase increased under high glucose condition. In the model group, PHB translocation occurred at 6 h and protein expression decreased at 48 h (P<0.01). Compared with the model group, 12.5-50 mg·L-1 Sophoral flavones reduced the contents of TGF-β1, MMP-2, collagen Ⅰ and collagen Ⅲ, increased the number of G1 phase cells, and increased the expression of PHB protein at 48 h (P<0.05), with no effect on the nuclear translocation of PHB. These results indicated that Sophoral flavones could prevent the proliferation of CFb induced by high glucose, the mechanism of which may be related to increasing the expression of PHB protein.

ABSTRACT

Objective To validate a cell infection-based quantitative RT-PCR for evaluating the potency of rotavirus vaccine. Methods According to the ICH ( the International Council for Harmonization) Harmonised Tripartite Guideline, the method was validated for its specificity, accuracy, precision, linearity and robustness. Results The method had good specificity as it could only amplify and detect the corre-sponding type of rotavirus strain. The recovery rates for determining the potency against rotaviruses of G2, G3 and G4 types were 97% to 108%. The percent coefficient of variation ( CV) of both intra-plate and in-ter-plate precision was≤2. 62%, while the intraday and interday CV was≤1. 76% and≤2. 27%, respec-tively. The CV between the two experimenters was≤7. 68%. The linearity range of the method was 4. 4-6. 5 UI for G2 type rotavirus, 3. 9-8. 3 UI for G3 type and 3. 5-8. 1 UI for G4 type. Good robustness was observed using the cells of 140 to 160 generations. Conclusions The cell infection-based quantitative RT-PCR was shown to have satisfactory specificity, accuracy, precision, linearity and robustness, suggesting that it was a suitable method for evaluating the potency of multivalent rotavirus live vaccines.

ABSTRACT

Objective To evaluate the immunogenicity and safety of a booster dose of live attenua-ted measles-mumps-rubella (MMR) vaccine for 4-year-old children and to provide references for reasonable arrangement of MMR immunization schedule. Methods Children aged 4 years (54-60 months) old were recruited and divided into three groups as follows: Group 8 months MR [receiving live attenuated measles and rubella(MR) vaccination at 8 months and MMR vaccination at 18 months],Group 8 months MMR(re-ceiving MMR vaccination at both 8 and 18 months) and Group 12 months MMR(receiving MMR vaccination at both 12 and 22 months). Active follow-up was conducted for safety evaluation after immunization of all subjects with the booster dose of MMR vaccine. Blood samples were collected before and 35 days after vacci-nation and analyzed by ELISA to detect serum antibodies to measles,mumps and rubella. Results A total of 514 subjects were enrolled in this study of safety evaluation and 469 of them received serologic detection of antibodies twice. The rate of adverse reactions following vaccination was 17.12% (general reactions accoun-ted for 94.21%) and no severe adverse reactions were reported. No significant difference in the rates of ad-verse reactions was found among the three groups (χ2=4.82, P=0.090). Subjects who were seropositive for measles, mumps and rubella increased after immunization with MMR vaccine, accounting for 100%, 99.79% and 99.79%,respectively. Geometric mean concentrations (GMC) against measles, mumps and rubella in all subjects were 1.35,3.05 and 2.13 times higher than what they were before the immunization. Levels of antibodies to measles,mumps and rubella were all increased significantly in the three groups after immunization with the booster dose of MMR vaccine (Fisher Exact Test, P=0.000). Conclusion The booster dose of MMR vaccine increases the levels of serum antibodies in children aged 4 years old with high safety. It suggests that two doses of MMR vaccine should be encouraged in the immunization program in China.

ABSTRACT

ObjectiveCorrect identification of the blood type is an important prerequisite for ensuring the safety of clinical blood transfusion. This study was to explore the causes of blood type discrepancy of blood donors between preliminary screening and recheck and to propose some countermeasures for the reduction of errors.MethodsThis retrospective study included 114 398 cases of blood donation from 2009 to 2015. The blood types of the donors were preliminarily screened with the paper board and rechecked after blood collection. We investigated the causes and number of errors in preliminary blood type screening and analyzed the failure rates in the high-temperature months (July, August and September), low-temperature months (December, January and February), and moderate-temperature months (the other six months).ResultsPreliminary blood type screening errors occurred in 164 of the cases, 157 (95.73%) in blood group identification, mainly misidentification of type B antigen (43.95%) and type A antigen (23.5%). The rate of blood group identification errors was significantly higher in the high-temperature than in the low- and moderate-temperature months (0.19% vs 0.12% and 0.12%, P<0.05).ConclusionMisidentification of types B and A antigens and high-temperature environment are the main causes of the errors in preliminary blood type screening for blood donors.

Objective:To investigate the status and influential factors associated with 2-week prevalence of fever and diarrhea among infants and young children at the age of 6-23 months in poor rural areas.Methods:A total of 8 735 rural infants and young children aged 6-23 months in 30 poor counties of Wuling Mountains and Luoxiao Mountains in Hunan Province were selected in August 2015,and the questionnaires were used to collect information on the prevalence of fever and diarrhea,person and families,and feeding status.The data for prevalence of fever and diarrhea in infants and young children were calculated,and multi-non-conditional logistic regression model were used to analyze the influential factors.Results:The 2-week prevalence of fever and diarrhea in infants and young children was 20.8% and 12.2% respectively.The ages (OR=0.66,95%CI 0.58 to 0.75),Dong ethnicity(OR=1.42,95%CI 1.17 to 1.74) and low body weight (OR=1.31,95%CI 1.11 to 1.54) were influential factors for fever among infants and young children in poor rural areas;female (OR=0.86,95%CI 0.76 to 0.98),12-17 months (OR=0.80,95%CI 0.69 to 0.93),18-23 months (OR=0.51,95%CI 0.43 to 0.60),other ethnic minorities (OR=1.70,95%CI 1.13 to 2.56),non-complementary feeding (OR=1.65,95%CI 1.05 to 2.59) and low body weight (OR=1.39,95%CI 1.14 to 1.70) were the influential factors of diarrhea among infants and young children.Conclusion:The 2-week prevalence of fever and diarrhea among infants and young children aged 6-23 months in poor rural areas were quite serious.Low age,Dong ethnicity,and low birth weight are high risk factors for fever.Male,no addition of complementary feeding,and low birth weight are high risk factors for diarrhea.

ABSTRACT

Objective:To study the effect of one-day outpatient intervention on gestational diabetes mellitus (GDM) patients,and to explore the pregnancy outcome relevant to GDM patients and their fetus.Methods:The GDM patients were divided into two groups according to their own intention to the one-day outpatient.According to systematic sampling method,we chose 200 GDM patients from the above 2 groups,respectively.The 200 GDM patients in the control group were matched the observation group with the age and gestational age,then the pregnancy outcome was tracked.Results:The control level and success rate for the two hours blood sugar after breakfast and hemoglobin A1c (HbA1c) in the observation group were better than those in the control group (P<0.001).The maternal complication rate (46.50%) and neonatal complication rate (21.50%) in the observation group were lower than those in the control group (71.50%,41.50%;P<0.001).The maternal complications rate of fetal distress,premature and the neonatal complications rate of fetal macrosomia,neonatal respiratory distress syndrome (NRDS),low weight,congenital heart disease,neonatal pneumonia,and rate in neonatal NICU were significantly lower than those in the control group (P<0.05).Conclusion:One-day outpatient intervention could control blood sugar effectively,reduce the maternal and neonatal complications.It is worth promoting.
