Objective We make a retrospective analysis , to compare to COPD group and discuss the risk factors and the clinical features in acute exacerbation in patients with ACOS to follow-up the exacerbating frequency after regular treatment in both two groups in one year. Methods There were 56 patients with ACOS and 80 patients with COPD from 2013 to 2015 in our hospital in 30%≤FEV1<80% in the stable phase. The common data of the enrolled patients included the age,sex,smoking, and allergic rhinitis or other allergic diseases in family. We analyzed laboratory index including PaO2,PaCO2,CRP,white blood cells,IgE of serums and compared the proportion of antibiotics,system used of glucocorticoid and noninvasive ventilation in hospitalization of acute exacerbation and followed up exacerbating frequency after using ICS united LABA/LAMA. Results The age and smoking index in the ACOS group were lower than the COPD group (P < 0.05). The allergic rhinitis or other familial allergic diseases,lower age of 60,the high IgE in serum were risk factor, in ACOS. In acute exacerbation, the PaCO2,IgE and WBC in serum were higher than that of the COPD group(P <0.05). The midian length of stay in hosipital was 12 days in the ACOS group and 8 days in the COPD group. The proportion of antibiotics,systemic administration of glucocorticoid and noninvasive ventilation in hospitalization of acute exacerbation in the ACOS group were higher than that of the COPD group (P < 0.05). The exacerbating frequency was decreased after using ICS united LABA/LAMA(1.2±0.6 vs 3.8±1.3,P < 0.05)in both ACOS and COPD groups. Conclusions The allergic diseases may participate in ACOS, in which it has familial tendency. In acute exacerbation, ACOS patients had even more inflammation and faster course than COPD patients. Using ICS united LABA/LAMA can reduce exacerbating frequency in ACOS.

0.05).Conclusions The local cell-mediated immunity of PTC is in the status of obviously suppressed.But the local impaired immune response against carcinoma is not associated with lymph node metastasis of PTC.

BACKGROUND: Precise clinical treatment of talar ischemic necrosis remains controversial at present.OBJECTIVE: To observe the changes in the stress and its distribution on talar trochlear articular surface in case of talar necrosis at different levels.METHODS: The present study adopted eight ankle specimens to establish the three-dimensional finite element model of ankle. Through changes in the talar necrosis volume of these models, this study analyzed the change law of talar trochlear articular surface stress and its distribution and calculated the critical necrosis volume of traumatic foot and ankle arthritis or talar collapse that may be induced by talar ischemic necrosis.RESULTS AND CONCLUSION: The experiment successfully established the three-dimensional finite element model of ankle. This study found that talar trochlear articular surface stress distribution showed little change in case of talar medial and lateral necrosis at a lower level; when medial talar necrosis volume reached (26.6±1.5)%, and lateral talar necrosis volume reached (35.0±2.5)%. Stress concentration phenomenon occurred in the boundary area between talar necrosis tissue and normal osseous tissue, and the stress area took the shape of irregular pattern. It is suggested that surgical treatment should be considered due to the high-risk induction of ankle-foot traumatic arthritis or talar collapse.

Objective To analyze the factors influencing the prognosis of patients with pancreatic cancer.Methods The clinical data of 276 patients with pancreatic cancer who had been admitted to our department from September 1995 to August 2005 were retrospectively analyzed.Cox regression analysis was used to screen out independent risk factors influencing the prognosis of patients with pancreatic head cancer or pancreatic body and tail cancer,and Kaplan-Meier method to calculate the median survival time.The effects of tumor location on the prognosis were examined by Log-rank and Breslow test.Results Cox regression analysis showed that the diameter of tumor,invasion of the superior mesenteric vessel and treatment method were the independent risk factors influencing the prognosis of patients with pancreatic head cancer;while age,lymphadenectasis and treatment method were the independent risk factors influencing the prognosis of patients with pancreatic body and tail cancer.The median survival time of patients with pancreatic head cancer and pancreatic body and tail cancer after radical resection were 460 days and 480 days,which were significantly longer than 240 days and 200 days of patients who received palliative treatment or gave up treatment.The median survival time of patients with whole pancreatic cancer was 117 days,which was significantly shorter than 330 days of patients with pancreatic head cancer and 300 days of pancreatic body and tail cancer.Conclusions Radieal resection is currently the best choice for pancreatic cancer.The prognosis is poor for patients with pancreatic head cancer(diameter≥4 cm)and invasion of the superior mesenteric vessel.Patients with age≤60 and lymphadenectasis are the factors resulting in poor prognosis of pancreatic body and tail cancer.The prognosis of patients with pancreatic head cancer and pancreatic body and tail cancer are close.Patients with whole pancreatic cancer is in the terminal stage with the worst prognosis.

OBJECTIVE:To observe the clinical efficacy of Chinese medicine inunction wet dressing therapy and helium neon laser in the treatment of rheumatoid arthritis.METHODS:Both groups received Methotrexate tablets,Salazosulfapyridine tablets,Loxoprofen tablets.Observation group were additionally treated with Chinese medicine inunction wet dressing therapy and helium neon laser with a treatment course of 30 days.RESULTS:The effective rate was 70.00% for control group and 93.55% for observation group,there was significant difference between two groups(P

OBJECTIVE The head of malleus (HOM) was regarded as the landmark for the middle cranial fossa approach,and its relationship with internal auditory meatus(IAM) was measured. The purpose of this study was to find a safe method to locate IAM. METHODS Twelve heads of adult cadaver fixed with 10 % formaldehyde (23 sides) were microsurgically dissected from the middle cranial fossa approach. The foramen spinosum,Ferrein's foramen,greater petrosal nerve,lesser petrosal nerve,facial nerve,HOM,arcuate eminence,superior petrosal sinus,semicircular canal,and IAM were exposed. First,blue lines method was used to locate IAM. Second,HOM as the landmark was used to locate IAM. RESULTS The angles between the SSC and the longitude axis of IAM are 58.52??4.84?。 A perpendicular line (AB) was drew from the center of HOM to the longitude axis of the temporal bone (the longitude axis of the superior petrosal sinus),line BC was drew from the anterior 30?(28.93?? 6.07?) to the line AB. On the line BC,fundus of IAM can be located (6.69?1.10) mm medial to HOM,the center of the internal acoustic pore can be located (20.1?1.48)mm medial to HOM. CONCLUSION In the middle cranial fossa surgery,HOM can be used to locate IAM and its surroundings structures when traditional landmarks are unrecognized.

Objective To evaluate the efficacy of nucleoside analogues (NAs) antiviral therapy on clinical outcome for hepatitis B virus (HBV)-related primary hepatic carcinoma patients after hepatectomy. Methods The clinical data of 156 HBV-related primary hepatic carcinoma patients after hepatectomy were retrospectively analyzed..According to whether accepted postoperative antiviral treatment, all patients were divided into control group (n = 80)and observation group (n = 76). The serum HBV DNA capacity, recurrence-free survival (RFS)and overall survival (OS)were compared between two groups. Results One week, 1 month, 2 months and 3 months after operation , the serum HBV DNA capacity of observation group was significantly lower than that of control group(P < 0.05). One year, 3 years and 5 years after operation, intergroup comparison of RFS rate of both groups showed statistical significance (P < 0.05) and 1 year, 3 years and 5 years after operation, the difference of OS rate of both groups indicated statistical significance (P < 0.05). Conclusion Standard NAs antiviral treatment for HBV-related primary hepatic carcinoma patients after hepatectomy ,can improve prognosis and prolong survival time. The inhibition the HBV copy active may be its mechanism.

Objective To investigate the clinical efficacy of electroacupuncture plus a multi-function cervical rehabilitation system in treating cervical spondylosis.Methods Sixty patients with cervical spondylosis were randomly allocated to treatment and control groups, 30 cases each. The treatment group received electroacupuncture plus treatment with a multi-function cervical rehabilitation system and the control group, electroacupuncture alone. After 30 days of treatment, changes in the pain score, the neck disability index, and cervical active range of motion and isometric muscle strength were observed in the two groups and the clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 96.7% in the treatment group and 93.3% in the control group; there was no statistically significant difference between the two groups (P>0.05). There were statistically significant pre-/post-treatment differences in the pain score, the neck disability index, and cervical active range of motion and isometric muscle strength in the two groups (P<0.01,P<0.05). There were statistically significant post-treatment differences in the neck disability index, and cervical active range of motion and isometric muscle strength between the treatment and control groups (P<0.05).Conclusions Electroacupuncture plus a multi-function cervical rehabilitation system is an effective way to treat cervical spondylosis. It can relieve the clinical symptoms in the patients.

Objective To evaluate the effects of alpha-lipoic acid (α-LA)on autophagy in human skin fibroblasts (HSFs). Methods HSFs at passage 3 - 5 were divided into several groups to be cultured with α-LA at final concentrations of 0, 0.01, 0.05, 0.10, 0.15, 0.20 and 0.50 mmol/L for 4, 12 and 24 hours, respectively. Methyl thiazolyl tetrazolium(MTT)assay was performed to evaluate cellular proliferative activity, monodansylcadaverin(MDC)staining to determine autophagy levels, and Western blot to measure the expression of the microtubule-associated protein 1 light chain-3B(LC3-B). Results After incubation for 24 hours, there was a significant difference in the proliferative activity of HSFs among all the groups (F = 10.41, P < 0.05), while no significant differences were observed after incubation for either 4 or 12 hours (F = 2.85, 1.34, respectively, both P > 0.05). MDC staining also showed a significant difference in the percentage of autophagosome-positive cells among all the groups after 24-hour incubation (F = 8.03, P < 0.05), but no significant difference after either 4- or 12-hour incubation (F = 0.11, 0.10, respectively, both P > 0.05). Western blot revealed that the degree of conversion from LC3-Ⅰ to LC3-Ⅱ(LC3-Ⅱ/LC3-Ⅰratio)was significantly different among all the groups after 24-hour incubation (F = 37.49, P < 0.05), but similar after 4- and 12-hour incubation (F = 3.38, 2.13, respectively, both P > 0.05). Conclusion α-LA may inhibit basal autophagy in HSFs.
