Methods:OPN mRNA and protein level were detected by fluorescent quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR)and Western blot in 41 cases of malignant salivary gland tumors,21 of benign salivary gland tumors and 10 of normal salivary gland tissues. The relationship between the relative content of OPN mRNA and protein and clinico-pathological features of salivary gland tumors were analyzed. Results:The differences of OPN mRNA and protein expression levels in various tissues (malignant salivary gland tumors,benign alivary gland tumors and normal salivary gland tissues) were statistically significant,and the mRNA expression levels were correlated significantly with node metastasis and TNMstage,the expression levels of OPN protein were correlated significantly with node metastasis and TNMstage(P

Digital CR of head and neck overcomes the disadvantage of regular X-ray radiography, which can not reveal bone and soft tissue position deficiency in one exposing, and reduces the X-ray radiation dose. Meanwhile, various factors decline the imaging quality, and images must be enhanced in order to meet demands of doctors clinical diagnosis. The general enhancement algorithms don't consider bodys structure difference and density characteristics. A new adaptive CR enhancement algorithms was proposed in this article, and head and neck images were processed with this method and compared with linear unsharp masking method. The results proved that the details of CR image enhanced were abundant and enhanced CR had good visual effect. SNR was high, as well as detail variance/background variance (DV/BV) indicating that this algorithms is suitable for head and neck CR medical image.

Whether allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the optimal treatment for adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (Ph - ALL) after the first complete remission (CR1) or not is still a controversial issue. Many studies have recently reported that adolescents and young adults with Ph- ALL may benefit from pediatric chemotherapy. Conventional baseline risk factors cannot satisfactorily predict prognosis, conversely, the early minimal residual disease (MRD) is the best stratification tool to offer different treatments for patients with different MRD status. Novel therapies, such as CAR-T cells and blinatumomab, have shown promising results in relapsed/refractory patients. Through comprehensive application of pediatric chemotherapy protocols, MRD driven strategy and novel therapies, it is hopeful to change the paradigm of how to treat adults with Ph - ALL in the future, and to bring improved outcomes and decreased adverse events.

Artificial lung, also called oxygenator, has the properties of oxygenation, heterotherm, blood store, filtration, and blood retrieval, oxygenates venous blood with low oxygen to arterial blood with high oxygen, similar to human physiological condition, and functions as an ideal artificial organ. Membrane artificial lung has been widely used in extracorporeal circulation of cardiovascular surgery, as well as rescue of respiratory failure, i.e. extracorporeal life support or extracorporeal membrane oxygenation. And the intravascular oxygenator has been primarily used in clinic. In particular, membrane oxygenator is essential for patients with severe disease, poor heart function, and long-duration operation. Currently, based on membrane material modification and optimization, as well as experimental and clinical evaluations of various properties, studies of artificial lung focus on improvement of gas exchange and biocompatibility, so as to provide reliable means of rescuing patients.

OBJECTIVE:To investigate the effects of anisodamine combined with oxytocin on labor process of lying-in women with prolonged active phase in the first labor process and related indicators of newborns. METHODS:216 lying-in women with pro-longed active phase in the first labor process were randomly divided into control group(108 cases)and observation group(108 cas-es). All lying-in women were artificially ruptured,based on it,control group was given 2.5 u Oxytocin for injection,adding into 500 ml 5% Glucose injection by intravenous infusion,the drip rate was appropriately adjusted based on contractions;observation group was additionally given 10 mg raceanisodamine hydrochloride,adding into 10 ml 5% Glucose injection by intravenous infu-sion by 5 min slow intravenous injection. The fetal heart was warded to closely observe the labor process during medication. The cervical maturity,labor process time,delivery mode and postpartum situation of lying-in women,Apgar score,body mass and inci-dence of adverse reactions of newborn in 2 groups were observed. RESULTS:The lying-in women cases with no less than 9 cervi-cal maturity,natural delivery rate and 5 min newborn Apgar score in observation group were significantly higher than control group, lying-in women cases with 7-9 scores and less than 7 scores,cesarean section rate,perineal/ straight cut rate and 24 h postpartum hemorrhage were significantly lower than control group,the second,the third and total labor process were significantly shorter than control group,the differences were statistically significant(P<0.05);there were no significant differences in the time of incubation period and active period,forceps delivery rate,body mass of newborn and incidence of adverse reactions in 2 groups (P>0.05). CONCLUSIONS:Anisodamine combined with oxytocin can accelerate the cervical dilation of lying-in women with pro-longed active phase,shorten labor process,reduce cesarean section rate and improve prognosis,it did not affect the body mass of newborns,with good safety.

Objective To study the treatment influences on immunity and tumor recurrence of oral canc -er patients with the combination therapy of hyperbaric oxygen treatment and postoperative adjuvant chemotherapy . Methods In the period from March 2011 to March 2014 ,84 patients were clearly diagnosed with oral cancer and randomly divided into hyperbaric oxygen treatment combined postoperative adjuvant chemotherapy group ( group A,n=42)and postoperative adjuvant chemotherapy group (group B,n=42).From day 1 prior to the last day of chemotherapy ,patients in group A were treated with hyperbaric oxygen ,and patients in group B were just accepted chemotherapy.After chemotherapy,we tested the levels of CD3 +,CD4 +,CD8 +and NK cells by flow cytometry, and the expression of IL -2,IL-4,IL-10 and INF-γby ELISA essay.All patients had been followed for two years.Results The levels of CD4 +and NK cells in group A were higher than group B (P<0.05),but the levels of CD3 +and CD8 +between the two groups were obviously different (P>0.05).Compared with group B,the ratio of CD4 +and CD8 +was increased in group A(P<0.05).The levels of cytokines involved IL -2,IL-4,IL-10 and INF-γin group A were higher than the levels of group B ( P<0 .05 ) .Follow-up results showed that pa-tients treated with hyperbaric oxygen combined postoperative adjuvant chemotherapy had less recurrence in 2 years(P<0.05).Conclusion Hyperbaric oxygen combined postoperative adjuvant chemotherapy can improve the patients′immune function ,and to be effective in preventing two years′recurrence .

Objective: To research the method of Establishing model of polymyositis with damp-heat syndrome. Methods: 45 guinea pigs were randomly divided into three groups, group A (normal group), group B (experimental myositis group, control group), Group C (damp-heat group). In the control group, the rabbit skeletal muscle homogenate Garver,s complete adjuvant for subcutaneous immunization was used to injecting into the original guinea pigs. Besides the above-mentioned immune method, the heat-damp model method was used (feigan diet, hot and humid environment and pathogenic micro-organisms and other complex factors) to establish the polymyositis model with damp-heat syndrome. The general situations, such as the serum muscle enzymes, light microscopy, electron microscopy changes in each group were observed. Results: The results showed that the clinical performance, serum creatase, the pathological changes of skeletal muscle, lungs, liver of guinea pigs in damp-heat group were similar to the human polymyositis with damp-heat syndrome. Conclusion: The model can be used to study the human polymyositis with damp-heat syndrome, and provide the pathogenic and theoretical basis for treating polymyositis by TCM.

Renal involvement is common in systemic lupus erythematosus(SLE).Treatment of lupus nephritis includes immunosuppressive and supportive therapy.The intensity of immunosuppressive therapy depends on the clinical and renal pathological disease activity.The long-term targets of treatment are to prevent lupus nephritis relapse and protect renal function.Complete remission is the goal in the induction phase,and long-term treatment is necessary in the maintenance phase.Individualization therapy and the side effects of immunosuppressive agents should be paid more attention.
