The antigens(3C9Ag)which could be recognized by the anti-lung cancer monoclonal antibody 3Ca were assayed with BA-ELISA immunobinding inhibition test in 50 lung cancer patients,21 patients with non-cancerous pulmonary diseases and 40 normal subjects.Meanwhile radioimmunoassay was used to determine serum CEA.It was found that the sensitivity,specificity and accuracy for 3C9Ag to diagnose lung cancer were 76%,90.5% and 80.3% respectively.Much higher positive rates could be found in NSCLC patients and in those with stage Ⅱ or Ⅲ cancer.3CsAg was superior to CEA in its sensitivity and accurracy.Combined assay with 3C9Ag and CEA could increase the positive rate.

We have trcated 40 cases of active peptic ulcer with Omeprazolc from Jun. 1990 to Mar. 1991. Compared with it, We have treated 40 cases of active peptic ulcer with Ranitidine during the same time. 80 patients with active peptic ulcer were divided into two groups. The age, scx and size of ulcer between the two groups have been compared. The ulcer diameter was from 3 to 20mm. The number of the ulcer was from 1 to 5.40 patients were treated with Omeprazole 20～40mg p. o. everyday. After a course of two weeks trcatment, the healing rate was 95%; 40 patients were treated with Ranitidine 300mg p. o. everday. After a course of six weeks the healing rate was 63%, The difference of the two groups was marked (P

MicroRNAs are endogenously expressed non-coding RNAs, which are composed of approximately 18 nucleotides to 25 nucleotides. Mature microRNAs regulate gene expression by base pairing with the 3'-untranslated region of target mRNAs. These mature microRNAs can degrade target mRNAs or inhibit translation. This process is a type of post-transcriptional regulation of gene ex-pression. Studies have shown that microRNAs are important in physiological and pathological processes, such as cell proliferation, cell differentiation, and cell death. This article provides an overview of the function of microRNAs in the regulation of macrophages.

Objective To evaluate the clinical efficacy of modified Angelica Fritilaria Sophorae Pill assisting transcatheter arterial chemoembolization (TACE) to treat primary liver cancer. Methods Totally 84 patients with primary liver cancer were randomized into combination treatment group (42 cases) and conventional control group (42 cases). The conventional control group received TACE treatment, the combination treatment group received modified Angelica Fritilaria Sophorae Decoction and TACE. The tumor volume, TCM syndrome score, life quality, immune function and toxicity reaction of both groups were observed. Results Clinical observation was completed with 37 patients in each group. After three courses of treatment, the objective tumor response rate was 91.9% in combination treatment group and 86.4% in conventional control group (P<0.05). The clinical symptoms (fever, abdominal pain, vomiting, fatigue) in both groups were improved (P<0.05), with significant difference between the two groups (P<0.05). After treatment, KPS scores increased (P<0.05) in combination treatment group, and the scores of combination treatment group were significantly higher than those of the conventional control group (P<0.05). After treatment, Th1 function level increased (P<0.05) in combination treatment group, and that was better than the conventional control group (P<0.05). The incidence of liver toxicity and gastrointestinal reaction in the combination treatment group was significantly lower than that in the conventional control group (P<0.05). Conclusion Modified Angelica Fritilaria Sophorae Pill can enhance the efficacy of TACE treatment to treat primary liver cancer, reduce adverse reactions, and improve life quality of patients with primary liver cancer.

Objective To investigate the effect of preoperative administration of Dextromethorphan (DM) on cough reflex of patients during tracheal extubation under general anesthesia after obstructive sleep apnea syndrome (OSAS) operation. Methods Forty ASA Ⅰ-Ⅱ adult patients scheduled for uvulopalatopharyngoplasty (UPPP) under general anesthesia were randomly divided into control group and DM group (n=20 in each group). Patients in DM group received 0.3 mg/kg DM and control group took 5 ml normal saline preoperatively. Cough reflex of patients and adverse effects were recorded during tracheal extubation. Results Cough reflex during tracheal extubation was remarkably suppressed in DM group as compared with control group (P

One patient with the pedicle screw threatening the aorta was treated with adjusting the position of pedicle screw by anterolateral approach. No nervous lesion was found after adjusting. Radiograph showed the position and length of screw at T11 left pedicle of vertebral arch were good. No adverse reaction was detected after 2-years of follow-up.

Objective To investigate the expressions of B7-H1 and Bcl-2 proteins in epithelial ovarian cancer,and to explore the association of the expressions of B7-H1 and Bcl-2 with clinicopathological features.Methods The expressions of B7-H1 and Bcl-2 proteins were detected by immunohistochemistry in 80 cases of epithelial ovarian cancer tissues and 20 normal ovary tissues.The association of the expressions of B7-H1 and Bcl-2 with the clinicopathological features was analyzed.Results The positive expression rates of B7-H1 and Bcl-2 in epithelial ovarian cancer tissues were 77.5％ (62/80) and 58.8％ (47/80),both higher than 15.0％ (3/20) and 10.0％ (2/20) in normal ovary tissues with significant difference (x2 =27.473,P ＜ 0.05 ; x2 =15.216,P ＜ 0.05).Both of Bcl-2 and B7-H1 expressions in epithelial ovarian cancer tissues were negatively correlated with the differentiation degree of epithelial ovarian cancer (x2 =9.367,P ＜ 0.01 ; x2 =11.702,P ＜ 0.01).The Bcl-2 expression in epithelial ovarian cancer tissues was positively correlated with the FIGO stage (x2 =7.766,P ＜ 0.01).The expression of B7-H1 was positively correlated with the expression of Bcl-2 in epithelial ovarian cancer (r =0.400,P ＜0.01).Conclusion The expressions of B7-H1 and Bcl-2 are up-regulated in epithelial ovarian cancer and they correlate to each other positively.The expressions of B7-H1 and Bcl-2 are correlated with the invasion and metastasis of epithelial ovarian cancer.The detection of B7-H1 combined with Bcl-2 may have an important clinical significance in the diagnosis and treatment for patients with epithelial ovarian cancer.

Objective To investigate left ventricular systolic function with mitral annulus motion velocity(Sa) with pulsed-wave Doppler tissue imaging(PW-DTI) in patients with coronary arteriosclerosis disease(CAD) after percutaneous coronary intervention(PCI).Methods 52 patients with CAD,who were determined by coronary artery angiography,were divided into two groups,PCI group(n=33) and non-PCI group(n=19).They were followed up with PW-DTI and conventional echocardiography before and 5 d,3 months and 6 months after intervention in PCI ones,before and 6 months after angiography in non-PCI ones.In PCI group,the patients were divided two subgroups: EF≥50% and EF=30%～50%.Results The Sa improved significantly in PCI group 6 months after intervention(P<0.001).EF correlated with Sa(r=0.705,r=0.770 pre-and post-intervention respectively,P<0.0001).Conclusion Sa can be used to evaluate left ventricular systolic function of CAD patients.

Objective To analyze the management of clinical pathways ( CP) in China. Methods Cross-sectional questionnaire surveys of 51 public hospitals with CPs in place in Shanghai, Hubei province and Gansu province were conducted from March to May of 2015. Results Among the 51 public hospitals with CPs, 48 ( 94. 1%) of them organized training on CPs, 48 ( 94. 1%) of them monitored CPs′implementation, and 40 (78. 4%) applied incentives for CPs′ implementation. But there were some issues and difficulties encountered in CPs′ implementation. Conclusions Comprehensive measures are necessary to improve the management of CPs at public hospitals of China.

Objective To analyze the implementation of clinical pathways ( CP) at public hospitals at different levels and in different regions in China. Methods The status of CPs′ implementation at 54 public hospitals in Shanghai, Hubei province and Gansu province was surveyed by questionnaires from March to May of 2015. Results 51 (94. 4%) of the surveyed public hospitals put in place clinical pathway(s), where the average CPs implemented were 45 and the average percentage of the cases using CPs was 52. 7%. There were great variations among these hospitals. In addition, the common diseases with definite diagnostic and treatment options were found with the highest implementation rates of CPs at such hospitals. Conclusions CPs are implemented widely at public hospitals of China, yet enhanced implementation strategies are expected to further CPs′adoption.
