Objective    To investigate the safety of endoscopic thoracic sympathicotomy in the treatment of primary hyperhidrosis based on ambulatory surgery mode. Methods    Retrospective analysis was performed on the clinical data of 158 patients with primary hyperhidrosis who received endoscopic thoracic sympathicotomy in the Affiliated Hospital of Zunyi Medical University from January 2019 to March 2021. There were 68 (43.2%) males and 90 (56.8%) females with an average age of 14-33 (20.5±3.1) years. The basic information of the patients, operation time, intraoperative blood loss, postoperative pain score, hospitalization expenses and postoperative complications were observed and recorded. Results    All surgeries were successfully completed and the patients were discharged as planned. The operation time was 41.8±13.9 min, the intraoperative blood loss was 10.5±7.3 mL, the postoperative anesthesia recovery time was 15.0±5.9 min, and the pain score was 3.0±0.9 points. The total length of hospitalization was 1.6±1.0 days. The total postoperative expenses were 9 471.7±1 698.9 yuan. Pneumothorax occurred after the operation in 3 patients. Telephone follow-up on the 30th day after the operation showed no recurrence of sweaty hands, pneumothorax or rapid heart rate, and no serious complications or death related to the day operation within 30 days after the operation. Conclusion    Endoscopic thoracic sympathicotomy based on ambulatory surgery mode is safe and effective in the treatment of primary hyperhidrosis.

Objective:To analyze the factors affecting olfactory disfunctions in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).Methods:This was a retrospective analysis. Eighty-eight patients with CRSwNP who underwent endoscopic sinus surgery in Beijing Anzhen Hospital from 2014 to 2018 were enrolled, including 22 males and 66 females, with the age of (48.1±11.3) years old(Mean±SD). Sniffin′ Sticks olfactory test, Lund-Mackay score and modified sinus CT olfactory cleft score, nasal resistance and acoustic reflex examination, blood routine and blood biochemistry test, serum specific IgE test were performed before surgery and nasal polyps of all patients were collected for eosinophil count during surgery. According to bilateral total TDI score, the patients were divided into normal olfactory function group and olfactory disfunction group. The clinical baseline data were compared between the two groups. According to the results of single factor analysis, factors which were significant different between the two groups and clinically useful indicators were further included in the multivariate Logistic regression model analysis, then a model predicting olfactory disfunction in patients with CRSwNP was initially established. P<0.05 was considered statistically significant. Results:Among 88 patients with CRSwNP, 32 (36.4%) patients were with normal olfaction and 56 (63.6%) patients were with olfactory disfunction, including 40 (45.5%) of hyposmia and 16 (18.2%) of anosmia. Tissue eosinophil count, blood eosinophil percentage and blood urea concentration had significant difference between the two groups (12.7[2.0, 52.3]/HP ( M[ P25, P75]) vs 38.6[16.2, 87.0]/HP, 2.75[1.60, 4.80]% vs 4.35[2.50, 6.60]%, (5.56±1.15) mmol/L vs (4.98±1.33) mmol/L, all P<0.05). Modified sinus CT olfactory cleft score and Lund-Mackay score except for ostiomeatal complex score were statistically significant between the two groups (all P<0.05). Multivariate Logistic regression analysis showed that the bilateral and total olfactory cleft score and blood urea concentration were statistically significant, in addition, the bilateral and total olfactory cleft score was a risk factor ( OR=2.108, 95 %CI: 1.407-3.159, P<0.001) and blood urea within a certain concentration was a protective factor ( OR=0.461, 95 %CI: 0.240-0.884, P=0.020). Further studies found that the area under the ROC curve of the model with tissue eosinophil count, blood eosinophil percentage, bilateral and total olfactory cleft score, total inspiratory volume and blood urea concentration was 0.888 ( P<0.01), which had good predictive value for olfactory disorders in CRSwNP. Conclusions:The modified sinus CT olfactory cleft score is closely related to the olfactory disorders in patients with CRSwNP. A certain degree of elevated blood urea concentration may have a protective effect on the olfactory function of patients with CRSwNP.

Objective To examine the prevalence of obstructive sleep apnea (OSA) in patients with acute coronary syndrome (ACS),and to evaluate the relationship of OSA with inflammatory biomarkers in ACS patients.Methods Patients with ACS treated at Beijing Anzhen Hopital from June 2015 to May 2017 were enrolled.Subjects were evaluated for OSA by sleep study,and were divided into a normal-mild OSA group (Apnea Hypopnea Index,AHI ＜ 15 times/h) and a moderate-severe OSA group (AHI ≥ 15 times/h).Laboratory examination and sleep study were monitored to analyze the effects of OSA on biomarkers by LSD-t test,Mann-whitney U test,or Chi-square test.Correlation analysis was performed to analyze the association of OSA with high sensitivity C-reactive protein (hs-CRP) by Spearman correlation anaylsis.Results A cohort of 836 patients with ACS were enrolled including 408 patients in the normal-mild OSA group and 428 patients in the moderate-severe OSA group.The levels of leukocyte(x 109L) [7.78 (6.33,9.86) vs 7.29 (6.01,9.16),P=0.006],neutrophils(× 109L) [5.05 (3.84,7.23)vs 4.80 (3.74,6.66),P=0.044],monocytes(x 109L) [0.42 (0.33,0.54) vs 0.39 (0.31,0.51),P=0.033],hsCRP(mg/L) [3.18 (1.10,11.52) vs 1.78 (0.65,6.46),P＜0.01],fibrinogen(g/L) [3.17 (2.87,3.74) vs 2.97 (2.59,3.50),P=0.002],and uric acid(μmol/L) [360 (302,422) vs 341(283,407),P=0.006] in the moderatesevere OSA group were significant higher than those in the normal-mild OSA group.AHI (correlation coefficient=0.171,R2=0.020,P＜0.01),ODI (correlation coefficient =0.201,R2=0.027,P＜0.01),and TSaO2 ＜ 90％ (correlation coefficient =0.105,R2=0.005,P＜0.01) were positively correlated with hs-CRP;minimal SaO2 (correlation coefficient=-0.100,R2=0.001,P=0.008) and mean SaO2 (correlation coefficient =-0.127,R2=0.006,P＜0.01) were negatively correlated with hs-CRP.Conclusions For patients with ACS,the level of inflammatory markers in the moderate-severe OSA group is significantly higher than that in the normal-mild OSA group.Hs-CRP is significantly associated with the severity of OSA.Diagnosis and monitoring of OSA should be considered in ACS management in the future.

Objective To observe the effect of injecting botulinum toxin type A ( BTX-A) into the tibialis anterior muscle on spasm and the walking function of stroke survivors with spastic foot drop and strephenopodia. Methods Fifty-six stroke survivors with spastic foot drop and strephenopodia were randomly divided into a tibialis anterior injection group ( Group TA) and a conventional injection group ( Group CG) , each of 28. Both groups had 50 U of BTX-A injected into the medial-lateral heads of the affected gastrocnemius and soleus muscles, and 35 U in-jected into each of two sites in the tibialis posterior. Group TA was additionally injected with 30 U in the tibialis ante-rior. Before the injection, as well as 2, 4 and 12 weeks afterward, both groups were evaluated using the modified Ashworth scale (MAS) for the plantar flexors and varus muscle groups, a 10-minute walking test (10 m-WT), a simple Fugl-Meyer assessment ( FMA) of the lower limb and a timed up and go test ( TUG) . Results Before the injection, there were no statistically significant differences in the average MAS, 10 m-WT, FMA or TUG results be-tween the two groups. After 2 weeks, however, the average MAS score of both groups had decreased significantly, and that improvement was maintained at 4 and 12 weeks after the injection. Moreover, 2, 4 and 12 weeks after the injec-tion, significant differences in the average MAS score were observed between the two groups. The average 10m-WT re-sults, FMA scores and TUG times of both groups also improved significantly, but there were significant differences between the two groups′10m-WT times and FMA scores after 2 and 4 weeks. Conclusions Injecting a small dose of BTX-A into the tibialis anterior can further relieve spasm in the tibialis anterior muscle and improve the walking a-bility of stroke survivors with spastic foot drop and strephenopodia.

Objective: To analyze the changing trends in etiologies of hospitalized patients with liver disease and provide clinical basis for the formulation of medical policy. Methods: Patients who were hospitalized in the Department of Infectious Diseases from 2006 to 2014 were selected as the research subjects. Data of patients with liver diseases were retrospectively analyzed to determine the proportion of main causes of infection, the proportion of different viral infections in viral hepatitis, and the changing trends in proportion of hepatitis B in different age groups. Kruskal-Wallis test was used for statistical analysis. Results: During 9 consecutive years, the overall proportion of inpatients with liver disease decreased continuously, but the number of patients increased. The top five etiologies of liver diseases were viral hepatitis, drug-induced liver disease, autoimmune liver disease, alcoholic and non-alcoholic fatty liver disease. The proportion of viral hepatitis decreased gradually, and the proportion of drug-induced liver disease and autoimmune liver disease increased markedly. Among viral hepatitis patients, hepatitis B, hepatitis C and hepatitis E were in the top three, with hepatitis B stabilized at around 70%, and the proportion of hepatitis C showed an upward trend. The hospitalization time of hepatitis B patients was gradually shortened, the difference was statistically significant (χ ² = 205.31, P < 0.001), and the hepatitis B patients were mainly distributed in age groups 31-40, 41-50, and 51-60, the total proportion was above 60%. The difference between the different years of the same age group was not evident, but the proportion of hepatitis B patients decreased gradually in the 14-23 –year- old age group, the difference was statistically significant (χ ² = 19.51, P = 0.01). Conclusion Liver disease still holds a principal position in the distribution of infectious diseases, and especially the cause of non-infectious liver disease require sufficient attention and concern. The use of hepatitis B vaccine has effectively diminished the infection rate, but the prevention and control of chronic hepatitis B infection is still facing challenges.

Objective: To explore the association between hypothyroidism and sleep breathing disorders in patients with coronary heart disease (CHD). Methods: A total of 784 patients with CHD were consecutively enrolled at the Emergency & Critical Care Center of Beijing Anzhen Hospital from June 2015 to May 2017. According to thyroid function test results, patients were divided into hypothyroidism group (79 cases) and non-hypothyroidism group (705 cases). All patients had undergone sleep monitoring. The sleep apnea status was compared between the two groups. Multivariate logistic regression and linear regression models were used to analyze the association between hypothyroidism and sleep breathing disorders in patients with CHD. Results: The proportion of females, mean body weight and body mass index in the hypothyroidism group were higher than those in the non-hypothyroidism group [26.6% vs.16.2%, (78.6±11.6) kg vs. (75.7±12.0) kg, (27.7±3.2) kg/m² vs. (26.6±3.5) kg/m², all P<0.05]. Patients in hypothyroidism group had a decreased average oxygen saturation (SaO₂) compared with patients in non-hypothyroidism group [ (93.2±2.9) % vs. (93.9±2.0) %, P=0.030]. In addition, events of hypoventilation in hypothyroidism group were significantly higher than those in non-hypothyroidism group[92.5 (45.8, 758.3) times vs. 68.0 (33.0, 125.0) times, P=0.013]. There were no significant differences in apnea hypopnea index, diagnosis of obstructive sleep apnea and other sleep breathing parameters between the two groups (P>0.05). A multiple linear regression analysis found that in patients with CHD, the correlation between hypothyroidism and average sleep SaO₂ was significant (β=-0.508, 95%CI -0.989--0.026, P=0.039). Conclusions: CHD patients with hypothyroidism had a lower sleep average SaO₂, and a higher sleep hypopnea events. There is a correlation between hypothyroidism and sleep hypoxia in patients with CHD.

Objective: To investigate the impact of moderate/severe obstructive sleep apnea (OSA) on the prognosis of acute myocardial infarction. Methods: We prospectively selected patients with acute myocardial infarction (AMI) who were hospitalized at the Emergency Critical Care Center of Beijing Anzhen Hospital from June 2015 to May 2017. Patients who met the inclusion criteria were examined with portable sleep respiration monitoring. Patients were divided into moderate/severe OSA group (apnea-hypopnea index (AHI)≥15 beats/hour) and no/mild OSA group (AHI<15 beats/hour) according to sleep AHI. The incidence of major adverse cerebrovascular events (MACCE) after discharge was compared between the two groups, and the independent risk factors of MACCE were analyzed. Results: A total of 432 patients were enrolled in this study, including 211 moderate/severe OSA patients (48.8%). Compared with no/mild OSA group,patients with moderate/severe OSA had higher body mass index ((27.17±3.22) kg/m² vs. (25.55±3.44) kg/m², t=-5.033,P<0.001), higher proportion of history of percutaneous coronary intervention (PCI) (18.5%(39/211) vs. 8.6%(19/221), χ²=9.076,P=0.003), and higher proportion of 3-vessel disease (31.3%(66/211) vs. 24.9%(55/221), χ²=10.196,P=0.017). The median follow-up time was 1.0 (0.7, 1.7) years. The incidence of MACCE in the moderate/severe OSA and no/mild group was 19.9%(42/211) and 11.3%(25/221), respectively. Kaplan-Meier analysis showed a higher cumulative risk of MACCE in patients with moderate/severe OSA (log-rank test,χ²=5.467, P=0.019). Multivariate Cox regression analysis showed that moderate/severe OSA (HR=1.915, 95%CI 1.016-3.611, P=0.045) and diabetes mellitus (HR=1.819, 95%CI 1.022-3.238, P=0.042) were independent risk factors for MACCE at 1 year post discharge in patients with AMI. Conclusions: Nearly half of AMI patients are complicated with moderate/severe OSA in this patient cohort. Coronary artery disease is more severe in AMI patients complicating with moderate/severe OSA. Moderate/severe OSA is an independent risk factor for MACCE at 1 year after discharge in patients with AMI. Whether the prognosis of AMI can be improved by intervention of OSA remains to be investigated. Trial Registration Clinical Trial.gov, NCT03362385.

To evaluate the gB antibody level of pseudorabies virus (PRV) in swine,a rapid test strip was developed.In the strip,the expressed protein of gB was labeled with colloidal gold,the staphylococcal protein A (SPA) and swine anti PRV antibody were blotted on the nitrocellulose membrane for the test and control lines,respectively.The specificity and sensitivity of the strip were detected with standard positive,negative and immunized sera of PRV,the results indicated that the strip was high specificity and sensitivity.Field swine serum samples were tested by the new strip and commercial IDEXX PRV gB ELISA kit,simultaneously.The agreement rate of the two methods was 91.04％.Furthermore,the dipstick assay based on the strip is rapid (5 min),sensitive and easy to perform.This suggests that the new strip is an acceptable alternative for field diagnosis.

Objective To investigate clinical value of miRNA-27-3p expressed in colorectal cancers,liver metastasis,and the peripheral blood,and analyze its target genes.Methods Among 78 cases of colorectal cancer patients,sera,colorectal cancers,and liver metastases were used to detect miRNA-27a-3p expressions with real-time quantitative polymerase chain reaction (RT-PCR) and analyze its clinical significance.We predicted miRNA-27-3p target genes,and confirmed the target genes and their correlation between miRNA-27a-3p and target genes.Results The expression level of miRNA-27a-3p in 78 cases of colorectal cancers was 3.13 ± 1.72,which was significantly higher than that in matched adjacent cancer tissues (1.06 ± 0.42) and control group (0.68 ± 0.27) (P ＜ 0.05).The expression level of miRNA-27a-3p in 27 cases of liver metastases was 3.48 ± 1.15,which was significantly higher than that in paired colorectal cancer tissues (2.34 ± 1.03) (P ＜0.05) and adjacent tissues (0.81 ± 1.14) (P ＜0.05).Expression levels of miRNA-27a-3p in patients with colorectal cancer tissues and peripheral blood had no significant difference in age,sex,serum carcinoembryonic antigen (CEA) levels,tumor location,and pathological types (P ＞ 0.05);however,it had positive significant difference in lymph node metastasis,liver metastasis,tumor node metastasis (TNM) staging (P ＜ 0.05).The expression of miRNA-27a-3p was negatively correlated with the expression of target gene GP73.Conclusions The higher expression was miRNA-27a-3p in peripheral blood and colorectal cancer tissues,higher risk of liver metastasis occurs.MiRNA-27a-3p might participate in the occurrence and development of colorectal cancer by regulating target gene expression of GP73.In peripheral blood of colorectal cancer patients,miRNA-27a-3p might be used for potential auxiliary diagnosis and predict liver metastasis.

Objective To investigate the epidemiological and clinical characteristics of measles in patients of different age groups in Northeast China in 2014.Methods The clinical data of patients with measles in ten hospitals of infectious diseases in Northeast China from January 2014 to June 2014 were collected.Patients were divided into <16 age group and ≥16 age group, and the epidemiology , clinical characteristics, treatment and prognosis of all patients were retrospectively reviewed .SPSS 17.0 was used for data analysis.Results There were 1 401 patients with measles, in which 402 were <16-year old, and 999 were ≥16-year old.Clinical manifestations were mainly maculopapule (100.0%), fever (84.58%), cough (85.80%), Koplik’ s spot (73.23%), pharyngeal hyperemia (71.23%), diarrhea (43.97%), expectoration (40.97%), tears (39.40%) and runny nose (30.55%).The incidences of Koplik’s spot, sputum, pharyngeal hyperemia and diarrhea in <16 age group were lower than those in ≥16 age group (χ2 =8.364, 29.768, 10.953 and 6.701, P<0.05 or <0.01); while the incidence of runny nose was higher than that in ≥16 age group (χ2 =6.703, P<0.05).Abnormalities were found in blood routine examination, C-reactive protein (CRP), liver and kidney function, serum electrolyte levels, myocardial enzymes, and so on.Increasing in WBC, PLT and creatine kinase isoenzyme (CKMB), and decreasing in WBC were observed in 38(9.45%), 122(30.35%), 279(69.40%) and 105(26.12%), patients in <16 age group, which were higher than those in ≥16 age group [45(4.5%), 14(1.40%), 347(34.73%) and 202(20.22%)], and the differences were of statistical significance (χ2 =12.593, 274.033, 139.385 and 5.830, P<0.05 or P<0.01).Increasing in alanine aminotransferase (ALT), CRP, total bilirubin level (TBil), creatine kinase (CK), and decreasing in albumin (Alb), K+, Na+, Cl-were observed in 70(17.41%), 7(1.74%), 38(9.45%), 7(1.74%), and 214(53.23%), 59(14.68%), 45(11.19%), 94(23.38%) patients in <16 age group, which were lower than those in ≥16 age group [668(66.87%), 89(8.91%), 277(27.73%), 714(71.47), and 268(26.83%), 339(33.93%), 642(64.26%), 450 (45.05%)], and the differences were of statistical significance (χ2 =281.230, 23.073, 50.687, 159.740, and 14.674,114.286, 44.268, 271.546, P<0.01).Laryngitis and pneumonia were the most common complications.The incidence of laryngitis in <16 age group was 12.69% (51/402), which was higher than that in ≥16 years group (93/999, 9.31%,χ2 =3.545, P<0.05);while the incidence of spot shadows demonstrated by X-ray in <16 years group ( 72.89%, 121/166 ) was higher than that in ≥16 years group (265/445, 59.55%,χ2 =9.249, P<0.01).Conclusions There are differences in clinical features of measles in patients between <16 age group and ≥16 age group.Basic immunization in children and revaccination in adults should be enhanced to control the epidemics of measles .
