Forty patients with subclinical hypothyroidism were treated by thyroid hormone (Levothyroxine or extract of thyroid). After treatment, plasma lipoprotein (a) level was decreased from (3.02?0.80)mmol/L to (2.74?0.75)mmol/L (P

Objective to investigate the curative effect of activated vitamin D3 combined with IFN-α on CCl4-induced hepatic fibrosis in BALB/c mouse model. Methods the experimental mice received 100 μL of 10% CCl4 intraperitoneally to induce a model of hepatic fibrosis,and the nor-mal control group were administrated with same volume of 0.9% saline(n = 6). the experimental mice then were randomly divided into four treat-ment groups and treated for six weeks:saline therapy group(0.9% saline,100 μL/mouse,n = 6),IFN-α therapy group(IFN-α 800 U/mouse,n =6),1,25-(OH)2D3 therapy group(50 μg/kg,by gavaged,n = 6)and combined treatment therapy group(combined treatment,n=6). Hepatic inju-ry and hepatic pathology were examined by HE staining and Masson staining. Interleukin-6(IL-6),interleukin-10(IL-10),tumor necrosis factor-α(tNF-α),transforming growth factor-β(tGF-β)and Smad3 were determined by real-time PCR and ELISA. Results Inflammatory cell infiltra-tion and periportal collagen deposition were significantly reduced in all the therapeutic group expect saline therapy group assessed by HE and Masson staining. the IFN-α therapy group,1,25-(OH)2D3 therapy group and combined treatment therapy group displayed significant decrease in Col1α1, IL-6,tNF-α,tGF-β and Smad3 expression and increase in IL-10 expression in liver tissue(P < 0.05). Conclusion the effect of 1,25-(OH)2D3 combined with IFN-α therapy is similar to separated treatment.

Objective To investigate the effect of nCPAP as pre-emptive ventilatory support strategy in severe bronchiolitis. Methods A retrospective analysis was made on cases with nCPAP as pre-emptive ventilatory support strategy for severe bronchiolitis in PICU of our hospital from August 2012 to September 2014. Results Seventy-nine children received nCPAP therapy in our PICU. Overall, nCPAP was successful performed in 69 children, 10 patients required intubations. PaO2 and PaO2/FiO2 in patients received intubations were lower than those in patients received only nCPAP before treatment (P < 0.05). There were significant improvements in PaCO2, PaO2, PaO2/FiO2, respiratory rate and heart rate in the patients received only nCPAP at 12 hours and 24 hours post-treatment (P < 0.05). For the 69 patients with hypercapnia received only nCPAP, PaCO2 was significantly reduced at 2 hours, 12 hours and 24 hours post-treatment (P < 0.01). Conclusion Clinically, nCPAP could improve the oxygenation and hypercapnia of patients with severe bronchiolitis. However, these patients, who suffered from severe bronchiolitis with minor PaO2 or PaO2/FiO2, appeared to require intubation as soon as possible.

ObjectiveTo analyze the clinicopathological characteristics and survival time of penile cancer after surgery.MethodsThe clinicopathological data of 93 cases of penile cancers patients treated from January 2002 to December 2010 were collected retrospectively.The Kaplan-Meier method was used to draw the survival function and calculate the survival rate.Log-rank test was further used to compare survival difference.ResultsThe median age of the 93 patients was 51 years ( range,23 to 82).Squamous carcinoma was most common with 87 eases (93.5％) in our group.Sixty-one patients were successfully followed up and the median follow up duration was 28 months(range,2 to 89 months).All 3 cases of verrucous carcinoma had progression free survive after surgery after follow up of 12,19,and 67 months.In the 55 patients with penile invasive squamous carcinoma,11 patients died of metastatic disease with a median survival time of 10 months ( range,2 to 24 months).Two years cumulative survival rate was 75.7％ (95％ CI 63.0％ to 88.4％ ).Six cases of 12 patients with lymph node metastasis died of penile cancer while only 5 cases of 43 patients without lymphnode metastasis died.The survival difference was significant (log rank,P =0.000).ConclusionsSquamous carcinoma is the most common type,and patients with lymphnode metastasis have poor prognosis.Verrucous carcinoma has good prognosis.

Objective To summarize the experience in open surgery for huge adrenal tumors in order to improve its safety and efficiency of this complicated surgical procedure. Methods Fortyfour consecutive patients with huge adrenal tumors underwent open surgery with mean long tumor diameter of 13 cm (9-34 cm), and autologous blood transfusion was prepared in routine. It was analyzed retrospectively for clinical data, perioperative complications and the effective and safety results of this procedure. Results The incision was oblique in lumbar region in 5 cases, subcostal unilaterally in 32 cases and abdomino-thoracic joint in 7 cases. There were 27 malignant tumors (61.4%) in 44 cases, 3 with hepatic invasion, 6 with thrombi extending into inferior vena cava, among which 2 needed translocation of artificial blood vessels and 3 needed cardio-pulmonary bypass. The mean blood loss was 1309 ml (100-3000 ml) in 41 cases(93.2%)and the autologous blood transfusion was used in 20 case (45.5%). There were 1 diaphragmatic injury, 1 pleura injury, 3 hemorrhage in large amount more than 15 000 ml and 2 peritoneal cavity infection.There were no perioperative deaths and 42 tumors (95.5%) were curatively resected. Conclusions Open surgery for huge adrenal tumors is a complicated surgical technique with high risk and large amount of blood loss. The key points to success are proper selection of incision, routine autologous blood transfusion, perfect surgical skills and good cooperation between different specialties.

Objective:To investigate the feasibility of detecting excision repair cross-complementing 1(ERCC1)and ERCC2 in peripheral venous blood instead of cancer tissues from esophageal squamous cell carcinoma patients. Methods:The expressions of ERCC1 and ERCC2 mRNA were detected by using RT-PCR in 39 cases of peripheral venous blood samples, esophageal squamous cell carcinoma tissues, and adjacent normal tissues. ELISA was used to determine the levels of ERCC1 and ERCC2 proteins in serum. The periphe-ral blood from 10 healthy volunteers was used as control. Results:Expression levels of ERCC1 and ERCC2 mRNA and protein were significantly higher in peripheral blood from healthy control than those in esophageal carcinoma patients (P<0.05). There was a positive correlation between the expression of ERCC1 and ERCC2 mRNA in peripheral blood and cancer tissues (P<0.01). Conclusion:The expression levels of ERCC1 and ERCC2 mRNA in peripheral blood can indirectly reflect their expression levels in human esophageal squamous cell carcinoma tissues.

Objective:To investigate the mRNA and protein expressions of steroid sulfatase (STS) in breast cancer tissues and normal breast tissues, and analyze its relationship with clinicopathologic characteristics. Methods:The mRNA and protein expressions of STS, in 40 cases of breast cancer tissues and corresponding paracancerous normal breast tissues, were examined by reverse transcription-polymerase chain reaction(RT-PCR)and immunohistochemistry. The correlation of STS expression level with clinicopathologic characteristics was analyzed. Results:STS protein was mainly expressed in the cytoplasm of breast carcinoma cells and epithelial cells in normal breast glands, but not in the stroma. It could be detected in the nucleus of carcinoma cells in 3 cases of breast cancer tissues, which was pathologically classified as invasive ductal carcinoma, invasive lobular carcinoma, and invasive micropapillary carcinoma. STS was not observed in interstitial tissues of breast glands. STS protein expression had positive correlation with its mRNA expressing level. The positivity of STS was 70.0% in breast cancer tissues, significantly higher than that of normal breast tissues (42.5%). The difference was significant (P =0.013). Stratified analysis showed that the positive rates of STS protein were significantly higher in premenopausal patients, the patients with lymph node metastasis, and those with advanced breast carcinoma than those in the matched normal breast tissues (P<0.05). Conclusion:Breast cancer tissues highly expressed STS protein to stimulate local estrogen production, thereby enhancing the progression and migration of breast cancer cells. In addition, as the tumor growth, locally biosynthesized estrogens may play more and more important roles.

Objective:To analyze the impact of different surgical methods on perioperative complication rate after radical cystectomy in patients over 75 years of age.Methods:A retrospective study reviewed 1 432 patients who received radical cystectomy from January 2003 to January 2015.A total of 239 pa-tients were ≥75 years (median age:78 years),of whom,74 patients (31.0%)suffered one or more perioperative complications.According to the different operation methods,patients could be divided into ileal conduit group and cutaneous ureterostomy group.The ileal conduit group included laparoscopic and open radical cystectomy with ileal conduit.The cutaneous ureterostomy group included transperitoneal laparoscopic,transperitoneal and extraperitoneal open radical cystectomy with cutaneous ureterostomy. Results:Perioperative complications were significantly associated with the patient’s age (P =0.012), American Society of Anesthesiologists (ASA)score (P =0.001),node staging (P =0.043),and dif-ferent surgical methods.Perioperative complications caused a prolonged hospital stay and delayed recovery (34 d vs.21 d,P =0.002).For different surgical methods,the perioperative complication rate of ileal conduit was higher than cutaneous ureterostomy (P =0.013).However,there were no significant differences between transperitoneal laparoscopic and open radical cystectomy with ileal conduit in perioperative complication rate (P =0.836).The perioperative complication rate was statistically signifi-cant among transperitoneal laparoscopic,transperitoneal and extraperitoneal open radical cystectomy with cutaneous ureterostomy (P =0.022).On multivariate analysis,age (hazard ratio =4.856,95% CI:1.465 -16.103,P =0.010),ASA score (P =0.008),and different surgical methods (P =0.016) were significantly associated with the perioperative complication rate.Conclusion:The perioperative complication rate after radical cystectomy in elderly patients was associated with the patients’age,ASA score,and different surgical methods.Patients who received extraperitoneal open radical cystectomy with cutaneous ureterostomy suffered fewer perioperative complications,which was an appropriate choice for elderly patients.

Objects To explore the effectiveness and safety of using the Cardio-O-Fix Plug occluder in the treatment of muscular ventricular septal defect(mVSD)in children.Methods 14 patients with mVSD were taken to the cardiology department of First Affiliated Hospital of Kunming Medical University from July 2015 to June 2021 as research subjects.They were divided into two groups:14 children who received Cardi-O-Fix Plug occluder as the experimental group,and 10 children who received Cardi-O-O-Fix mVSD occluder as the control group.Electrocardiogram and transthoracic echocardiography were used to evaluate the occlusive efficacy and incidence of complications 1 day after surgery and 1 month,3 months,and 6 months of follow-up.Results Among the 24 pediatric patients,22 cases were successfully occluded,and 2 cases were unsuccessful(1 in the experi-mental group and 1 in the control group).The success rate of the experimental group was 92.8%(13/14),while the success rate of the control group was 90.0%(9/10).The average surgical duration of the experimental group was(71.93±14.85)minutes,while the average surgical duration of the control group was(90.70±19.78)minutes.There was a significant statistical difference between the two groups(P<0.05).Both the experimental group and the control group did not experience serious complications during surgery and follow-up.There was no significant difference in cardiac ultrasound indicators(including left ventricular ejection fraction,left ventricular end-diastolic diameter,and pulmonary artery pressure)between the two groups at different time points(P>0.05).Conclusion Trans-catheter closure of mVSD using Cardi-O-Fix Plug occluder in children is both safe and effective.The incidence of arrhythmia is low in the short,medium and long term.
