ObjectiveTo explore the clinical significance of detecting serum intact parathyroid hormone (iPTH) and drainage fluid parathyroid hormone (dPTH) after thyroidectomy in forecasting parathyroid function.MethodsThe clinical data of 95 thyroidectomy patients in the same treatment group from March 2018 to September 2018 were retrospectively analyzed, which in the Department of Thyroid-Breast Surgery, the Second Affiliated Hospital of Kunming Medical University. According to the surgical method, the patients were divided into 3 groups: isthmus and unilateral thyroidectomy (partial resection group, n=33), total thyroidectomy (total resection group, n=33) and total thyroidectomy and central lymph node excision (radical resection group, n=29). The negative pressure drainage tube was placed in the operative area. The iPTH and serum calcium were detected before and the first day after operation. The dPTH was detected in the first day and the second day after operation. Serum calcium, iPTH and dPTH were statistically analyzed.ResultsThere were no significant differences in operative time, hospital stay and blood loss between the total resection group and the radical resection group (P>0.05), but the partial resection group were all less than the other two groups (P<0.01). On the first day after operation, the iPTH in the three groups were lower than that before operation, and the iPTH was significantly decreased in the total resection group and the radical resection group, with statistically significant difference (P<0.05). The dPTH in the three groups were significantly increased on the first and second day after operation (P<0.05), but there was no statistically significant difference between the three groups (P>0.05). There was no statistically significant difference in serum calcium between the three groups on the first day after operation (P>0.05).ConclusionsThe levels of iPTH, dPTH and serum calcium after thyroidectomy can comprehensively forecast the parathyroid function. Preventive calcium supplementation can reduce the occurrence of postoperative symptomatic hypocalcemia, which is conducive to the recovery of parathyroid function.

Neurosyphilis is a group of clinical syndromes in which Treponema pallidum invades the nervous system and causes damage to the meninges, blood vessels, brain parenchyma or spinal cord. At present, there is no highly specific and sensitive method for the diagnosis of neurosyphilis, and its diagnosis mainly depends on clinical manifestations, abnormal cerebrospinal fluid and the comprehensive judgment of clinicians. Current studies show that some cytokines and chemokines are promising for laboratory detection of neurosyphilis. This article reviews the research progress of neurosyphilis from the aspects of traditional laboratory testing, polymerase chain reaction testing, cytokine and chemokine testing, and existing diagnostic criteria for neurosyphilis, in order to provide a reference for clinical testing and follow-up research.

Objective To investigate clinical significance of serum VEGF-C level and C-erbB-2 protein expression in patients with breast cancer. Methods Sixty-two female patients with breast invasive ductal cancer and breast benign lesion were respectively selected. Serum VEGF-C level was detected by enzyme-linked immunosorbent assay (ELISA) before operation and at one month after operation, and C-erbB-2 protein expression in tissues of breast cancer was detected by immunohistochemistry. Then, the relationship between serum VEGF-C level and clinicopathologic characteristics and C-erbB-2 protein expressions wereas analyzed. Results The serum VEGF-C level before operation in breast cancer patients〔(279.65±17.34) pg/ml〕 was significantly higher than that in breast benign lesions patients 〔(167.26±12.15) pg/ml〕, P＜0.01. In breast cancer patients, the serum VEGF-C level before operation was higher than that at one month after operation 〔(209.45±15.23) pg/ml〕, P＜0.01. The serum VEGF level was related to tumor stage (P＜0.05) but not to patient age, tumor size, menopause status , lymph node metastasis or not and ER and PR expression (Pgt;0.05). The positive expression rate of C-erbB-2 protein in breast cancer patients (54.84%, 34/62) was significantly higher than that in breast benign lesion patients (11.29%, 7/62), P＜0.01. Moreover, the positive expression rate of C-erbB-2 protein in breast cancer patients with axilla lymph node metastasis (69.44%) was significantly higher than that without axilla lymph node metastases (34.62%), P＜0.05. The serum VEGF level increased with increasing expression intensity of C-erbB-2 protein and there was positive correlation between them (r=0.813，P＜0.05). Conclusions The serum VEGF-C level in breast cancer may be conducted as an assisted marker to differential diagnosis of breast tumor. C-erbB-2 is related to lymph node metastasis of breast cancer patients. There is synergistic effect between VEGF-C and C-erbB-2 in the lymph node metastasis way of breast cancer.

Methods The epidemiological information and clinical characteristics of 400 patients with pandemic influenza A (H1N1) virus infection hospitalized in Beijing 302 Hospital from May to December, 2009 were analyzed retrospectively by descriptive epidemiology. One-way ANOVA was used to assess the results. Results H1N1 virus infection preferentially affected adolescents and young adults. The mean age of the patients was 23 years. A total of 189 (47.0%) of the patients had an identifiable epidemiologic link to another confirmed patient. The most common symptoms were fever (98.8%), cough (85.8%) and sore throat (58.5%). The main physical signs were pharyngeal portion congestion (94.0%) and antiadoncus (49.5%). The number of leukocytes in the peripheral blood was normal or low. The decreased serum iron and elevated C-reaction protein were found in 82.3% and 72.6% of the patients. There was significant difference in the duration of fever and viral shedding from throat swabs among the patients who accept the antiviral medication within the different time. Conclusion H1N1 virus infection preferentially affects adolescents and young adults, and presents with influenza-like illness. The clinical course of H1N1 virus infection is generally mild. The change of C-reaction protein and serum iron may be favorable for the diagnosis of H1N1. Early antiviral treatment may shorten the duration of fever and viral shedding.
Objectives To investigate the correlation between blood total cholesterol (TC) and prognosis of idiopathic sudden sensorineural hearing loss (ISSNHL) and to provide references for clinical treatment and prognosis assessment. Methods We included 232 ISSNHL patients with total deafness in Wenzhou Central Hospital from June 2015 to March 2017 using a prospective cohort design. Recording information including age, gender, hypertension, diabetes mellitus, vertigo, level of blood total cholesterol (TC), level of triglyceride (TG), level of low-density lipoprotein (LDL-C) and LDL/HDL ratio (LDL-C/HDL-C) were collected. Correlation between the prognosis of ISSNHL and blood total cholesterol were analyzed by univariable and multivariable logistic regression analysis. Results The clinical effective rate of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L was higher than that of patients with TC lower than 5.2 mmol/L (univariable: RR=6.49, 95%CI 3.16 to 13.30, P<0.001; multivariable-adjusted covariates: RR=6.15, 95%CI 2.66 to 14.3,P<0.001) with significant difference. No significant difference was found between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (univariable: RR=1.02, 95%CI 0.52 to 2.00,P=0.960; multivariable-adjusted covariates: RR=1.61, 95%CI 0.55 to 4.73, P=0.386). Gender-specific analysis showed for both male and female groups, the effective rates of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L were significantly higher than those of patients with TC lower than 5.2 mmol/L. There was no significant difference between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (P>0.05) in either male group or female group. Conclusion The current study suggests that patients with levels of TC ranging from 5.2 mmol/L to 6.2 mmol/L predicts the best prognosis.
Thirty patients with obstructive jaundice were investigated for serum complement-3 (C3) and plasma fibronectin (FN).The levels of C3 and FN of the juandiced patients were higher than that of thirty patients without obstructive jaundice (Ｐ＜0.01). As compared to pre-operation, the level of C3 of the jaundiced patients decreased obviously within two weeks after operation(Ｐ＜0.01), and recovered in the third week after operation. The level of FN of the juandice patients decreased evidently within one week(Ｐ＜0.01), and recovered in the second week after operation. However, the levels of C3 and FN of the patients without obstructive jaundice changed slightly after operation (Ｐ＜0.05). The high levels of C3 and FN of jaundiced patients may be relative to the latent infection. Consumption and immune imparing may be the reasons of C3 and FN to decrease.
Objective To explore the inducing factors, the serum total immunoglobulin E (IgE) and specific IgE of bronchial asthma in Mianyang children, for better control of childhood asthma. Methods A total of 1 288 cases of asthma who were hospitalized in pediatric respiratory ward or asthma clinic from March 2013 to February 2016 were enrolled in the study. All cases complied with the diagnostic criteria for acute episode of childhood bronchial asthma revised in 2008 by the National Children’s Asthma Cooperative Group. The causes of asthma attack were asked by doctors, and the patient’s serum total IgE and specific IgE was tested. Results Respiratory tract infections were the most common cause (1 057 cases, 82.1%), which was followed by weather changes and exposure to cold air (694 cases, 53.9%), and then food (304, 23.6%). The risk of asthma induced by respiratory infections was highest in <2-year old group (358 cases, 97.5%), and lowest in 10-14-year old group (42 cases, 33.3%), with a decreasing trend with age (χ2trend=239.865, P<0.001). Food was also an important inducing factor, and seafood was the most frequent (121 cases, 39.8%). Total serum IgE was positive in 868 cases (67.4%). The positive rate in <2-year old group (52.6%) was the lowest, and the positive rate in 10-14-year old group (89.7%) was the highest, with an increasing trend with age (χ2trend=88.055, P<0.001). Serum specific IgE was positive in 733 cases (56.9%). The positive rate in <2-year old group (37.1%) was the lowest, and the positive rate in 10-14-year old group (92.6%) was the highest, with an increasing trend with age (χ2trend=150.361, P<0.001). The progressive rate of dust mites in inhalation and dietary allergens was highest (668 cases, 51.8%), which was followed by house dust (431 cases, 33.4%). Conclusions The most common inducing factor for bronchial asthma in Mianyang children is respiratory tract infection, followed by the weather changes and cold air exposure, and then food. Detection of serum total IgE and specific IgE is more valuable in elderly children with bronchial asthma.
