OBJECTIVE:To explore clinical efficacy and compliance of different doses of calf pulmonary surfactant combined with nasal intermittent positive pressure ventilation (NIPPV) in the treatment of neonatal respiratory distress syndrome (NRDS). METHODS:90 children diagnosed as NRDS were collected from neonatal department of our hospital,and were divided into high-dose group,middle-dose group and low-dose group by random number table method,with 30 cases in each group. 3 groups received NIPPV combined with calf pulmonary surfactant;the dose of calf pulmonary surfactant in high-dose group,middle-dose group and low-dose group were 100,70,40 mg/kg,respectively. Blood gas indexes,treatment,hospitalization duration,treatment cost,the incidence of compliance were compared among 3 groups. RESULTS:Before treatment,there was no statistical signifi-cance in pH,PaCO2,PaO2,SaO2 among 3 groups(P>0.05);after treatment,above indexes of 3 groups were all improved signifi-cantly,and the high-dose group was significantly better than middle-dose group and low-dose group,with statistical significance (P<0.05). There was no statistical significance in duration of ventilation,oxygen therapy duration,cure rate and treatment cost among 3 groups(P>0.05). Medication times and hospitalization time of high-dose groups were significantly lower or shorter than those of middle-dose group and low-dose group,with statistical significance (P<0.05). The rate of complication in high-dose group,middle-dose group and low-dose group were 20.0%,23.3% and 16.7%,respectively,there was no statistical significance (P>0.05). CONCLUSIONS:Calf pulmonary surfactant combined with NIPPV could effectively improve the blood gas status of newborn with NRDS. High dose of calf pulmonary surfactant can reduce hospitalization time and doesn’t increase treatment cost and the rate of compliance.

Objective:To investigate the role of transforming growth factor β1 (TGF-β1) in multi-drug resistance in small cell lung cancer and its clinical significance.Methods:The mRNA and protein expressions of TGF-β 1 in H69 and H69AR cells were detected by real-time PCR and Western blot,respectively.After silence of TGF-[β1,the sensitivity of H69AR to drugs was detected by CCK8 assay.The expressions of TGF-β1 in lung cancer and paracarcinoma tissues were examined by QRT-PCR and immunohistochemistry.The relationship of TGF-β 1 expression with clinical pathological features and prognosis of patients was studied.Results:Compared to H69,the mRNA and protein expressions of TGF-β1 in H69AR cells were significantly increased by (5.93±0.47) and (8.49±1.92) folds,respectively (P＜0.01).Transfection ofTGF-β1 siRNA resulted in a decrease of TGF-β1 expression by 70.432％ in H69AR ceils (F=21.20,P＜0.01) and an increase insensitivity to chemotherapeutic agents of H69AR cells (t=4.576,P＜0.05).Compare with the paracarcinoma tissues,the expression of TGF-β1 was significantly increased in small cell lung cancer tissues (t=13.925,P＜0.01),which was closely related with clinical stage,chemosensitivity and overall survival (all P＜0.05),but not related with gender,age (both P＞0.05).Conclusion:TGF-β1 is involved in the regulation of small cell lung cancer multidrug resistance,which may be a potential marker to evaluate the chemosensitivity and dinical prognostic for small cell lung cancer.

To clarify the meaning, role and significance of the new idea of the modern basic theory of traditional chinese medicine, We clarified its origin and evolution starting from the basic concept of idea in this paper, re-vealed the basic connotation and relationship of ideas, scientific ideas, Chinese medicine ideas, and the new ideas of the modern basic theory of traditional Chinese medicine, and tried to give proper definitions; summarized three roles of scientific ideas. According to this basis, we demonstrated the new idea is the scientific ideas with core spirit run-ning through rational questioning, scientific testing, research and conclusion being accepted three-point line cen-tral interlocking; and have three roles changing the theory of traditional chinese medicine, guiding the innovative research on chinese medicine and elevating the scholars' thoughts. We proposed yin and yang to refer to the hypothesis of body's physiology and pathology and prevention and treatment effects, given an empirical analysis a feasible way of medicine and philosophy separation and yin and yang turning to medicine; displayed the guidance of new idea and to show the scientific connotation and scientific value of the theory of traditional Chinese medicine.

Objective To investigate the clinical features, effective treatment, survival and prognostic factors of second primary tongue squamous cell carcinoma (SPTSCC) after nasopharyngeal carcinoma (NPC) radiotherapy. Methods The clinical data of 35 cases with SPTSCC after NPC radiotherapy were analyzed retrospectively. Kaplan-Meier method, Log-Rank test and COX proportional hazard mode was performed for statistical analysis. Results 3-year and 5-year overall survival rates were 55 % and 47 %, respectively, lymph node metastasis rate was 5.71 %. Univariate analysis indicated that gender (χ2 = 8.89, P = 0.00), T classification (χ2= 5.58, P= 0.02), clinical stage (χ2 = 8.51, P= 0.04) and treatment methods (χ2 = 29.37, P = 0.00) were important factors of prognosis. Multivariate analysis showed that treatment methods (P = 0.00) and T classification (P = 0.03) were independent prognostic factors. Operative treatment group had better prognosis than the non-operative treatment group, the difference was statistically significant (P <0.05), male patients in the risk of SPTSCC was higher than the female patients, and the incidence of SPTSCC was increased along with extension of the time after NPC radiotherapy. Conclusion The rate of the lymph node metastasis is lower for SPTSCC after NPC radiotherapy and treatment patterns and T stage are independent prognostic factors. Long-term follow-up after NPC radiotherapy is necessary to the early diagnosis of SPTSCC, so that to give surgery or combined therapy with surgery in order to achieve a good effect.
