RESUMEN
Objective:To investigate the distribution of traditional Chinese medicine (TCM) syndromes in patients with coronary heart disease (CHD) in 6 months after interventional therapy, and to analyze relevant influencing factors. Method:The clinical data of 1 000 patients with coronary heart disease in 6 months after interventional therapy, including the four diagnosis information of TCM, were collected, and the distribution of TCM syndromes and the influencing factors were analyzed. Result:Among 48 kinds of information about the four diagnostic methods of TCM, chest pain was the most frequent (98.10%), among 9 kinds of common TCM syndrome types, blood stasis was the most frequent (89.90%), and the others were heart-Qi deficiency syndrome, phlegm turbidity syndrome, cold-dampness syndrome, kidney-Qi deficiency syndrome, heart-Yin deficiency syndrome, kidney-Yin deficiency syndrome, Heart-Yang deficiency syndrome and kidney-Yang deficiency syndrome in turn. Among 6 common TCM syndrome types, Qi deficiency and blood stasis syndrome were the most frequent (35.40%), and the others were phlegm turbidity and blood stasis syndrome, cold congealing heart pulse syndrome, Qi-Yin deficiency syndrome, heart-kidney Yin deficiency syndrome and heart-kidney-Yang deficiency syndrome in turn. There was no significant difference in sex ratio among different syndrome types . Patients with heart-kidney Yang deficiency syndrome had no significant difference. Compared with the average age of other syndromes, there were significant differences. Common complications included hypertension, diabetes, cerebrovascular diseases and dyslipidemia, among which hypertension had the highest frequency, with significant differences from other diseases (P<0.05). Phlegm, turbidity and blood stasis were found in patients with hypertension. The risk of syndromes was higher (OR=3.29, 95% CI [2.11, 5.05]), while the risk of cold congealing heart pulse syndrome was lower (OR=0.56, 95% CI [0.32, 0.98]), the risk of Qi and Yin deficiency was higher (OR=2.88, 95% CI [2.01, 4.99]), whereas the risk of heart and kidney Yang deficiency was lower (OR=0.54, 95% CI [0.29, 0.95]) when complicated with cerebrovascular diseases. The risk of Qi deficiency and blood stasis was higher (OR=2.97, 95% CI [2.05, 5.28]), while the risk of heart and kidney Yang deficiency was lower (OR=0.54, 95% CI [0.29, 0.95]), the risk of phlegm turbidity and blood stasis was higher when complicated with dyslipidemia (OR=3.55, 95% CI [2.32, 5.29]), and the risk of heart and kidney Yang deficiency was lower (OR=0.54, 95% CI [0.29, 0.95]). The time distribution of the disease had obvious seasonal characteristics. Conclusion:The main distribution characteristics of TCM syndromes in 6 months after coronary heart disease intervention are basically the same as those in patients without intervention. The main TCM syndromes are Qi deficiency and blood stasis syndrome, phlegm turbidity and blood stasis syndrome, cold congealing heart pulse syndrome, Qi-Yin deficiency syndrome, heart-kidney Yin deficiency syndrome and heart-kidney-Yang deficiency syndrome. The distribution pattern may be related to age, complications and seasons.
RESUMEN
To explore the application of endoscopy and clinical effect of endoscopic resection of benign tumor in infratemporal fossa. The clinical data of 11 patients with benign tumors in infratemporal fossa admitted to the Department of Otorhinolaryngology Head and Neck Surgery and Skull Base Surgery of the Affiliated Hospital of Qingdao University from January 2016 to September 2018 were retrospectively analyzed. There were 6 males and 5 females, with the age ranging from 11 to 63 years old. The main clinical manifestations were pharyngeal foreign body sensation, submaxillary pain, maxillofacial numbness and tongue numbness. Imaging examination showed that the tumor was round and had a clear boundary with the surrounding tissue. All the patients underwent endoscopic surgery. Appropriate surgical approach was selected according to the location of the tumor and its relationship with the internal carotid artery. The endoscopic surgical approaches included trans-oropharyngeal approach in 7 cases, trans-lateral pterygomandibular raphe approach in 1 case and trans-medial pterygomandibular raphe approach in 3 cases. The pathological results, prognosis, complications and relapse of patients were summarized through descriptive statistics. The tumors were completely resected under endoscope in all patients, and there was no significant complication occurred after surgery. The average pain VAS score was 3.1 after surgery and average hospital stay was 5.9 d. The postoperative pathological diagnoses consisted of 6 cases of pleomorphic adenoma, 4 cases of neurilemmoma and 1 case of basal cell adenoma. All patients were followed up regularly from 6 to 39 months without recurrence of tumor. Endoscopic resection of benign tumors in infratemporal fossa has the advantages of minimal damage, rapid recovery, few complications, and definite curative effect, which can be used as an important alternative for surgical treatment of benign tumors.
RESUMEN
OBJECTIVE@#To evaluate the value of anti-carbamylated protein (CarP) antibody in the diagnosis of rheumatoid arthritis-associated intersitial lung diseas (RA-ILD).@*METHODS@#Clinical and laboratory data and serum samples of patients with RA between December 2017 and June 2019 in Department of Rheumatology, General Hospital of Ningxia Medical University were collected. The patients were subclassified as RA-ILD and RA-without ILD based on computed tomography scans of the chest, Enzyme 1inked immunosorbent assay (ELISA) was used to assess anti-CarP antibody in the serum of each group. The occurrence of ILD and other laboratory indexes were analyzed. Comparison of measurement data between the 2 groups was performed by two independent sample t-test or Mann-Whitney U nonparametric test, while the count data were compared by Chi square test; Receiver operating characteristic curve (ROC) was drawn to determine the cut-off value of anti-CarP antibody to RA-ILD diagnosis and to analyze its diagnostic efficacy.@*RESULTS@#The anti-CarP antibody level in the RA-ILD group was 21.14 (12.29, 29.75), which was significantly higher than that in the RA-without ILD group 11.6 (6.66, 19.05) (P=0.000). The difference was statistically significant (P<0.05). The positive rate of anti-CarP antibody in RA-ILD group (53%) was significantly higher than that in RA-without ILD group (16%) (P<0.05); There was no significant differences in the levels of rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) between the two groups (P>0.05). The age and disease activity score (DAS28) in the RA-ILD group were significantly higher than those in the RA-withhout ILD group (P<0.05). The proportion of men and smoking in the RA-ILD group was higher than that in the RA-without ILD group, but the difference was not statistically significant. The ROC curve showed that the anti-CarP antibody had a cut off value of 20.56 U/mL, with the sensitivity of 53.50%, and specificity of 84.20%, the area under the ROC curve were 0.76. Spearman correlation analysis showed that rheumatoid factor (RF) and age were positively correlated with anti-CarP antibody (r=0.172, P=0.043; r=0.200, P=0.006). Anti-CarP antibody level was not associated with the DAS28 score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), anti-CCP antibody, swollen joint count, and tender joint count (P>0.05).@*CONCLUSION@#The anti-CarP antibody level in RA-ILD patients is higher than that in RA-without ILD, suggesting that anti-CarP antibody may have a role in the development of RA-ILD.

Objective To explore risk factors of congenital malformations (CMs) and to evaluate its impacts on adverse pregnancy outcomes (APOs). Methods A prospective cohort study was conducted among pregnant women who received the first antenatal care from March 2013 to February 2016 in the reproductive center, obstetrics clinics, infertility clinics and ultrasound department of Hunan Provincial Maternal and Child Health Hospital. Corresponding information from pregnant women and their spouses were collected. Univariate and multivariate Logistic regression were used to screen possible risk factors of CMs and evaluate the impacts of CMs on other APOs. Results The study showed that women had history of non-standard BMI, smoking, hepatitis, pregnancy-related complications, gestational diabetes mellitus, infertility and using assisted reproductive technology before pregnancy; had no folic acid taking, active and passive smoking, drinking, uneven diet, high intensity physical activity during pregnancy increased the risk of CMs in offspring. Furthermore, the history of spouse smoking and eating betel nut also increased the risk of CMs in offspring. CMs might increase the risk of preterm birth, very preterm birth, low birth weight, very low birth weight, and perinatal mortality. Conclusions There are many risk factors of CMs. Knowing these risk factors, and giving them optimal prevention strategies and effective intervention measures are important measures in preventing the occurrence of CMs and other APOs.

OBJECTIVE@#To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction.@*METHODS@#Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period.@*RESULTS@#After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year.@*CONCLUSION@#Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

<p><b>OBJECTIVE</b>To evaluate the outcome of core decompression with bone impaction grafting for the treatment of osteonecrosis of femoral head.</p><p><b>METHODS</b>Totally 39 cases (46 hips) of osteonecrosis of femoral head were treated with core decompression and impaction bone grafting. According to the Association Research Circulation Osseous (ARCO) system, 3 hips were graded for stage 1,16 for stage 2a,7 for 2b,11 for 2c, and 9 for 3.The Harris hip score (HHS) was evaluated before operation and at the latest follow-up.</p><p><b>RESULTS</b>In all these patients, 22 hips had hormone-related lesions, 11 had alcohol-related lesions, and 13 had idiopathic lesions. The average HHS was changed from (66 ± 6.6) before surgery to (80.2 ± 9.7) after surgery during an average follow-up of 26 months(from 9 to 48 months). The postoperative HHS showed no significant difference among osteonecrosis of femoral head due to different etiologies.Also,the postoperative HHS and clinical effectiveness were not significantly different among patients with different preoperative stages.The postoperative outcome was excellent in 7 cases, good in 23 cases, mild in 4 cases,and poor in 12 cases. The rate of excellent and good was 65% in this series,with 78% for patients with early stages and 52.6% for those with grade 2c or higher lesions. The femoral head collapsed in 7 cases,and 5 of which were preoperatively graded as in stage 2c and higher. The postoperative complications included intertrochanteric fracture (n=1) and infection (n=1). Four hips were converted to total hip arthroplasty. All of other hips had no obvious progression of osteonecrosis.</p><p><b>CONCLUSIONS</b>Core decompression with bone impaction allografting is effective for the treatment of osteonecrosis of femoral head. Patients with lesions in earlier ARCO stages can have better outcomes.</p>

RESUMEN
Objective@#This paper analyzes the changing trends of lower limb strength and flexibility in colleges in Ningxia for 14 years, and provides a reference for government and school to jointly guide college students to improve their lower limb strength and flexibility.@*Methods@#Data of physical health of 19 to 22 years old college students in Ningxia were collected from 2000-2014. Mean value, standard deviation and index compliance were used to describe the development trend of lower limb strength and flexibility indexes.@*Results@#From 2000 to 2014, the variation trend of lower limb strength of boys and girls in ningxia university was basically the same, and they all decreased first, then increased and then decreased(P<0.05). The variation trend of flexibility of boys and girls was basically the same, rising first and then falling (P<0.05). The mean values of standing long jump and sitting forward bend of boys and girls were higher in rural area than in urban area (P<0.05). There was no age group difference in the mean of standing long jump of girls in 2014, and no age group difference in the mean of standing long jump of boys and girls in other years (P<0.05).@*Conclusion@#The lower limb strength and flexibility of boys and girls in Ningxia from 2000 to 2014 showed a declining trend, and effective intervention measures should be taken in time.
RESUMEN
Objective@#To understand the current situation of infrastructure construction and sanitation practice of school canteens in China and to provide a reference for improving food safety in school canteen and sanitation management level.@*Methods@#Stratified sampling method was adopted to select the surveyed schools. Information regarding school canteen infrastructure and sanitation practice was collected through questionnaires. Chi-square test was used to compare the difference in passing rate on the survey indices among different school types.@*Results@#In environmental sanitation, 91.0% of the school canteen was rated as good and in personal hygiene, 92.8% of the employees were rated as good. The overall health level of urban schools was better than that of township schools, and non-boarding schools was better than that of boarding schools, with statistically significant differences(P<0.01). 67.1% of school canteens provided with independent food outlets while 98.7% of school canteens without independent food stores. The qualified rate of washing facilities in the dining area was 94.7%, and the qualified rate of distance between the canteen and the pollution source was 92.5%. Nearly all the employees held canteen catering service license (99.0%) and the health qualification certificate (99.5%). Most of the school canteens (98.7%) established the safety rules and regulations, including the food retention sample system. Nearly 61.5% schools initiated the principal meal program.@*Conclusion@#Sanitation management in the canteens of primary and secondary schools in China is generally satisfactory, with some canteens still fail to meet the standard requirements. More supervision from schools and relevant government departments (market supervision, health and education departments) is needed to provide students with a clean and heathy campus canteen.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the incidences and characteristics of the ribs and intraspinal abnormalities in surgical patients with congenital scoliosis.</p><p><b>METHODS</b>We conducted a retrospective study of the medical records and spine radiographs of 118 patients underwent surgical treatment between January 2010 and March 2011 with congenital scoliosis. The average age was 14 years (3-50 years).Fifty-two were male and 66 were female patients. The rib and intraspinal abnormalities were compared in different vertebral anomalies. Pearson's χ(2) test were used to analyze the incidence of anomalies of the ribs and vertebrae, as well as intraspinal anomalies.</p><p><b>RESULTS</b>A total of 57 (48.3%) patients were found to have intraspinal abnormalities.Split cord deformities were identified to be the most common intraspinal anomaly (32.2%), followed by syringomyelia (21.2%).Sixty-nine patients (58.5%) had rib anomalies, which occurring on the concavity of the scoliosis was most frequent. The patients with mixed deformity and failure of segment were found to have a higher incidence of rib anomaly than those with failure formation (χ(2) = 14.05, P < 0.01). The patients with multiple level malformations were found to have significantly higher incidence of rib anomaly than those with single level malformation (χ(2) = 27.50, P < 0.01).Intraspinal anomalies occurred in 42 of 69 patients (60.9%) with rib anomalies and 15 of 49 patients (30.6%) without rib anomalies in congenital scoliosis. The occurrence of intraspinal malformation has significant difference with or without rib anomalies in congenital scoliosis (χ(2) = 10.5, P < 0.01).</p><p><b>CONCLUSIONS</b>The intraspinal malformation is common in patients with mixed defects and failures of segmentation. The rib anomalies occurring on the concavity of the scoliosis is most frequent. The incidence of intraspinal anomaly is significant higher in the patients with rib anomalies than those without rib anomalies. Both the occurrence and type of rib anomaly, combined with vertebral deformity are helpful in forecasting the occurrence of intraspinal abnormalis.</p>

<p><b>OBJECTIVE</b>To observe the protective effect and mechanism of intermittent hypobaric hypoxia (IHH) on cardiomyocytes induced by hydrogen dioxide.</p><p><b>METHODS</b>Male guinea pigs were divided randomly into two groups (n = 10): intermittent hypoxia group (IHH), and control group (non-IHH). The IHH guinea pigs were exposed to a simulated 5,000 m high altitude and hypoxia in hypobaric chamber for 28 d, 6 h/d. The control guinea pigs were kept in the same environment as IHH except hypoxia exposure. Cardiomyocytes were enzymatically isolated from left ventricle of non-CIHH or CIHH guinea pigs. The contractile was assessed in guinea pigs by a video-based motion edge-detection system. The contents and activities of malondialdehyde(MDA), lactate hydrogenase(LDH) and antioxidant enzymes were evaluated by using biochemical methods.</p><p><b>RESULTS</b>1. Hydrogen peroxide could induce contractile and diastole dysfunction, the latent period was longer in IHH cardiac myocytes. 2. After hydrogen peroxide(300 micromol/L, 10 min) perfusion, LDH and MDA contents in supernatant increased significantly in non-IHH and CIHH cardiomyocytes (P < 0.01), Whereas the contents of MDA and LDH in IHH cardiomyocytes were lower than those in non-IHH cardiomyocytes (P < 0.01). 3. The activities of superoxide dismutase (SOD) and catalase (CAT) were significantly increased in the myocardium of IHH guinea pigs, after hydrogen peroxide (300 micromol/L, 10 min) perfusion, SOD and CAT activities decreased significantly in non-IHH and CIHH cardiomyocytes (P < 0.01), whereas the activities of SOD and CAT in CIHH cardiomyocytes were still higher than those in non-IHH cardiomyocytes.</p><p><b>CONCLUSION</b>IHH had a protective effect on cardiomyocytes injury induced by hydrogen peroxide, which might relate with its antioxidation effects.</p>
