Objective To evaluate the efficacy of jaw thrust device in the upper airway obstruction. Methods Thirty-five ASA Ⅰ or Ⅱ patients aged 18-64 yr with body mass index < 30 kg/m~2 undergoing elective surgery under general anesthesia were included in this study. The anesthesia face mask was placed and held tightly by 4 straps of JTD and connected to the anesthesia machine. Anesthesia was induced with midazolam, propefol, fentanyl and atracurium. When muscle relaxation was achieved, tracheal intubation was not performed. The airway obstruction was assessed by airway peak pressure and stridor score (breathing sounds detected by auscultation over the trachea). And then tracheal intubation was performed, and the patients were mechanically ventilated. Results There was no significant difference in airway pressure and stridor scores between JTD and jaw thrust maneuver. Conclusion JTD can effectively lift the jaw and improve the upper airway obstruction.

Objective: To establish a radioresistant model of non-small-cell cancer A549, and to provide the experimental basis for further researchonradioresistance. Methods: The cell number and the dose of radiation therapy were confirmed. The intermittent radiation were used to induce the radioresistant cell model. The morphology of cells were observed with an inverted phase contrast microscope. Colony formation was used to identify the radioresistance of the RA549 cell. Results: RA549 cells were longer and bigger than A549 cells; surviving fraction of RA549 was significantly increased than A549. Conclusion: Intermittent radiation can successfully induce the radioresistant cell model of lung cancer cells.

Objective To study the modulation effect of adrenomedullin (ADM) on hypoxia pulmonary hypertension in rats.Methods Twenty-four male Wistar rats were randomly divided into control group ( n =8), hypoxic group ( n =8), hypoxic with ADM group ( n =8). ADM was subcutaneously administered into rats of hypoxic with ADM group by mini-osmotic pump (300 ng/h). After two weeks hypoxic challenge, systolic pulmonary arterial pressure (sPAP) and mean pulmonary arterial pressure (mPAP) were evaluated by a right cardiac catheterization procedure. Mean systemic artery pressure (mSAP) was measured. The ratio of right ventricular mass to left ventricular plus septal mass [RV/(LV+S)] was detected.Results sPAP, mPAP and RV/(LV+S) significantly increased in hypoxic rats compared with controls ( P

Objective:To investigate the efficacy and safety of a treatment regimen based on daratumumab in patients with high-risk relapsed refractory multiple myeloma(MM)with mSMART 3.0 score.Methods:Clinical data were collected from 16 patients with mSMART3.0 score high-risk relapsed refractory MM treated at the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from May 2020 to May 2023,all of whom received daltezumab-based regimen(regimen drugs including dexamethasone,isazomib,bortezomib,lenalidomide).The efficacy and safety of the treatment were retrospectively analyzed.Results:The median age of 16 patients was 63.5(47-70)years old,including 10 cases of IgG type,2 cases of IgA type,and 4 cases of light chain type.The curative efficacy was judged in all 16 patients,with an overall response rate of 93.75％(15/16),including 4 cases of strict complete remission(sCR),1 case of complete remission(CR),2 case of very good partial remission(VGPR),partial remission(PR)in 5 cases,and minor remission(MR)in 3 cases.The median follow-up time was 11(2-30)months,and the median progression-free survival and median overall survival were not achieved in 16 patients at the median follow-up period.The hematologic adverse effects of the treatment regimen using daratumumab-based were mainly neutropenia,and the non-hematologic adverse effects were mainly infusion-related adverse reactions and infections.Conclusion:Daratumumab-based regimen for the treatment of relapsed refractory MM patients with high risk of mSMART3.0 score has better efficacy and safety.

The commodity specification and grade of Chinese medicinal materials is a measure of the quality of traditional Chinese medicines (TCMs), which directly impacts on the safety and effectiveness of clinical medicines. It is an urgent problem to establish a set of standards which can both interpret the scientific connotation of the commodity specification and grade of Chinese medicinal materials and play a significant role on clinical medicines as well as markets. This paper reviews the research methods of the commodity specification and grade of Chinese medicinal materials such as sensory evaluation, chemical assessment, biological evaluation, and cited the applications of various methods for the classification of TCMs. It provides technical support for establishing standards of the commodity specification and grade of Chinese medicinal materials, and also constructs scientific basis for clinical rational drug use.

OBJECTIVETo investigate the clinical efficacy of psycho-behavior therapy for premature ejaculation (PE).

METHODSA total of 58 PE patients that met the study criteria were treated by psycho-behavior therapy, 2-3 times a week, for a 6-time course. After the treatment, the therapeutic effect was assessed by observation of the changes in the patients' CIPE-5 scores.

RESULTSThe rates of cure, effectiveness, ineffectiveness and overall effectiveness were 46.55% (27/58), 32.76% (19/58), 20.69% (12/58) and 79.31%, respectively. The CIPE-5 scores of the patients were elevated from 7.97 +/- 2.30 before the treatment to 22.50 +/- 6.64 after it, and the differences were statistically significant. The psycho-behavior therapy obviously prolonged the ejaculation latency of the patients, increased the sexual satisfaction of both the patients and their spouses, lessened the patients' sexual anxiety and nervousness, and decreased the difficulty in retarding ejaculation, with statistically significant differences from pretreatment.

CONCLUSIONPsychobehavior therapy has remarkable therapeutic effect on premature ejaculation.

OBJECTIVETo evaluate the prognostic factors in treating primary liver cancer (PLC) patients by Pi-strengthening and qi-regulating method (PSQRM), thus providing evidence and optimizing Pi-strengthening and qi-regulating program.

METHODSClinical data of 151 PLC patients treated by PSQRM at Oncology Department, Guangdong Provincial Hospital of Traditional Chinese Medicine from May 2007 to March 2009 were retrospectively analyzed. The univariate analysis was determined to analyze possible prognostic factors. Selected key factors were introduced into the COX proportional hazard model, and multivariate analysis was carried out.

RESULTSThe 1-year survival rate was 21.85%, the median survival time was 6.80 months, and the mean survival time was 8.98 months. The univariate analysis showed that Chinese medicine (CM) syndrome types, clinical symptoms at the initial diagnosis, ascites, tumor types, ratios of foci, portal vein tumor thrombus, intrahepatic metastasis, a-fetoprotein (AFP) levels, total bilirubin classification, albumin classification, Child-Pugh classification, and domestic staging of liver cancer were significant prognostic factors (P < 0.05). The statistic data of multivariate analysis indicated that CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer were independent factors influencing prognosis (P < 0.05).

CONCLUSIONThe prognosis of PLC treated with PSQRM is determined by multiple factors including CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer.
