Transforming growth factor β1 (TGF-β1) is a member of cytokine superfamily.Recent studies reveal that the abnormality of TGF-β1 and its receptors is strongly related to genesis,progression and prognosis of lung cancer.It plays an important role in early diagnosis,stage and assessment of treatment and prognosis of lung cancer.

General practitioners from community health service institutions in Shijingshan,Mentougou,Haidian,Chaoyang,Fengtai and Dongcheng Districts of Beijing were selected to take the examination of chronic wounds management.Questionnaire survey was also performed on the status of community chronic wounds management,medical service motivation,influencing factors and their demand for training.Among 204 general practitioners,55 (27.0％) had mastered basic knowledge,98 (48.0％) passed the examination and 51 (25.0％) failed.The results showed that 179 (87.7％) had changing dressing service,36.8％ offered out-patient consulting service,17.6％ performed surgical debridement,only 10 (4.9％) provided home chronic wounds care service and 2 (0.9％) of them carried out long-term follow-up.According to the motivation survey,all the practitioners expressed the willingness to help the patients and win their trust.Most of the practitioners claimed no supporting from their institutions(91.7％) and chronic wounds management was excluded from daily routine.Furthermore,heavy work load(82.8％) and lack of professional knowledge(80.9％)were also considered to be main obstructive factors.The survey showed that the majority of physicians required classroom teaching (90.1％),case analysis (86.8％),operating video (92.6％) and other teaching forms.More low level doctors(97.1％)had the desire to pursue further specialist training than higher level physicians (56.7％).The results of our investigation indicate that general practitioners in community heath service institutions have strong learning motivation for chronic wounds management and systematic training of knowledge and practical skills in this field should be provided.

[Objective]To assess whether calcitonin exerts an chondroprotective action in unstable knees which induce experimental osteoarthritis and its effect to MMP-1.[Method]Twenty 6-month New Zealand rabbits underwent anterior cruciate ligament transaction(ACLT) and were divided into two groups (ACLT group and ACLT+CT group) randomly after transaction on day 7 postsurgery. ACLT+CT group rabbits received a daily subcutaneous injection of salmon calcitonin at a dose of 5 IU per kg of body weight for six weeks.ACLT group were treated with the normal saline at the same dose. All animals were sacrificed 7 weeks postsurgery. The articular cartilage degeneration of medial femoral condyle was evaluated at mascroscopically and microscopically. The mRNA expression and tissue level of MMP 1 was detected by RT-PCR and immunohistochemistry.[Result]Cartilage degradation in ACLT group was significantly more severe than that in ACLT+CT group both in microscopic grading scale and in Mankin's grading scale (P

Intraparotid facial nerve schwannoma (IFNS) is a rare benign tumor. The management of IFNS is very challenging because of the lack of appropriate methods for preoperative diagnosis, which is often conducted intraoperatively in most cases. This article reviewed the literature on IFNS recorded in PubMed from 1958 to 2014 and described in detail its clinical manifestations, diagnoses and differential diagnoses, and treatment options. Accurate diagnosis for IFNS mainly depends on intraoperative observation and postoperative histological examination. Preoperative facial nerve function, localization, and adherence, as well as preferences of IFNS patients are important factors to consider in the decision-making process for IFNS management to optimize the outcomes. Surgical resection is usually reserved for patients with facial function of House-Brackmann grade III or worse; otherwise, conservative treatment can be adopted.

The pattern/symptom differentiation system in acupuncture treatment is lack of the unique characteristics and advantages in theory and clinical practice and it just rigidly adopts the methods of pattern/symptom differentiation of the other disciplines in TCM. In fact, it is necessary to have the unique and more practical theoretic system to guide acupuncture treatment. According to the characteristics of acupuncture in diagnosis and treatment, the acupoints selection based on "disease-symptom-location" combination becomes the law of acupuncture treatment. The acupoints selection based on "disease-symptom-location" combination is the expression to concretize the diagnosis and treatment of disease under the guidance of pattern/syndrome differentiation. Both of them are originated from the general principles of TCM and for the particular disciplines of TCM. The acupoints selection based on "disease-symptom-location" combination benefits the promotion and application of acupuncture.

Abdominal incisional hernia is a common complication of abdominal surgery,of which the two major direct causes are surgery wound healing and intra-abdominal pressure.Therefore,the factors causing poor wound healing and intra-abdominal pressure are incisional hernia incentives.Surgery is the only radical method to cure it,including open surgery and laparoscopic surgery.This review contains two contents,the summary of the current research and the prospects.

Objective To investigate the effect of nutrition support therapy on quality of life in patients with advanced tumors.Methods 70 patients with advanced tumors were randomly divided into the observation group and the control group,each group had 35 cases.The control group was given conservative treatment,together with the ordinary liquid,semi-liquid or diet.The observation group was given nutrition support therapy on the basis of conservative therapy.The nutrition and immune index and symptom score,quality of life were compared between the two groups.Results The nutrition,immune indexes (Alb,BMI and NK) and symptom score (malaise,anorexia,insomnia,pain) of the observation group were significantly improved(t =7.92,6.98,5.56,7.41,6.47,5.61,4.52,all P ＜ 0.05),which were significantly better than those of the control group(t =4.42,4.10,4.03,6.42,5.60,4.83,4.23,all P ＜0.05).The physical function,role function,emotional function,cognitive function score and total score of the observation group were significantly higher than those of the control group,the differences were statistically significant (t =8.12,6.08,5.12,4.78,4.32,all P ＜ 0.05).Conclusion Nutrition support therapy can improve the nutritional status of cancer patients in advanced stage,relieve symptoms,improve immune function and quality of life,which is worthy of clinical application.

Objective To observe the efficacy of Danhong injection combined with low-molecularweight heparins in treating unstable angina pectoris.Methods One hundred and three cases of unstable ansina pectoris were enrolled and divided into group A and B,Group A were given Danhong injection and lowmolecular-weight hepafins,Group B were given routine treatment.Results The overall response rate of group A was 90.7％ and it was 74.0％ for group B.The difference was significant (x2 =4.90,P＜0.05).Conclusion Treatment with Danhong combined with low-molecular-weight heparins produced a good outcome in the patients with unstable angina pectoris.

ObjectiveTo study the effects of dl-3n-butylphthalide on study and memory abilities and hippocampus expression of MMP-9 in rat model of radiation injuries of brain.MethodsWistar rats were divided into radiation group radiated by linear accelerator and control group.Morris water test were taken to study the learning and memory ability of rats in each group before irradiation and 120 d after irradiation.ResultsMorris water maze test results showed that:in the academic test,compared with model group,high-dose butylphthalide group and low dose butylphthalide group had significantly shorter escape latency( (79.61 ± 7.17 )s,(43.64 ± 4.72)s,(42.15 ±4.19 ) s) and decreased number of errors ( 36.43 ± 6.59,14.58 ± 4.22,13.66 ± 3.91 ) (P ＜ 0.01 ).In the memory test,compared with model group,high-dose butylphthalide group and low dose butylphthalide group had significantly longer the former platform quadrant time respectively (30.09 ± 3.68 ) s,( 31.25 ± 3.17 ) s vs ( 17.57 ±4.29) s and faster swimming speed respectively (P ＜ 0.01 ).ConclusionButylphthalide can significantly reduce hippocampal neurons expression of MMP-9,which indicates that butylphthalide has curative effect on radiation brain injuries by regulating the expression of MMD-9.
