Transforming growth factor-β is an important cytokine with various bioactivities, including embryonic development, wound healing, chemotaxis and cell cycle regulation. Epithelial-mesenchymal transition (EMT) is the main pathway of tumor cell to obtain the ability of invasion and metastasis. The TGF-β is the key factor known to induce EMT in cancer cells and plays an important role in the process. In recent years, some progress has been obtained. Some TGF-β inhibitors have approved in the market or in clinical trials. TGF-β inhibitors can play an important role on the treatment of tumors, glaucoma, liver and kidney fibrosis disease and scar repair. Novel TGF-β inhibitors reported in recent years were reviewed in this article.

Objective To explore the influence of Toxoplasma tachyzoites infection on motility of human spermatozoa in vitro, and explain its possible mechanism. Methods Semen samples obtained from 10 healthy volunteers by masturbation were prepared by the swim-up technique. The samples were then inoculated at 37 ℃ with different concentrations of live Toxoplasma tachyzoites varying among 1?103/ml (Group A), 1?104/ml (Group B), 1?105/ml (Group C), 1?106/ml (Group D), 1?107/ml (Group E) and Group F containing Ham’s F-10 only as the negative control. Motion parameters were analysed by Computer-aided sperm analyzer(CASA) in 0 hour, 1 hour, 2 hours, 4 hours respectively. Modalities of spermatozoa and possible adherence and/or agglutination were observed under the light microscope. Results Distinct adhesion of spermatozoa to Toxoplasma tachyzoites and agglutination were noticed. In all the motion parameters, progressive motility was affected most and dependent upon the incubation time and tachyzoites concentration. Progressive motility showed a significant difference between Group E and the control (P

Objective To compare the effect of 89Sr radionuclide therapy and radiotherapy in the treatment of metastatic cancer pain of vertebral column. Methods 80 patients with cancer pain of vertebral metastasis in the second People's hospital of Yibin from April 2015 to April 2017, were randomly divided into the control group treated by radiotherapy treatment (n=40) and the the observation group treated by 89Sr radionuclide therapy(n=40), and the effect of treatment were compared between two groups. Results In the observation group, the total effective rate of pain response in patients with metastatic cancer pain of vertebral column was 85.0%, and the control group was 82.5%. There was no significant difference between two groups. The onset time of treatment in the observation group was (6.5±1.7)d, significantly shorter than that of the control group (12.9±2.6)d, and the difference was statistically significance (P<0.05). Conclusion The application of 89Sr radionuclide therapy in the treatment of vertebral metastatic pain is equivalent to the radiotherapy in improving the pain response, but the efficacy could be achieved in a short period of time, so it is worth popularizing widely in clinical practice.

Purpose The determination method of rhG-CSF bio logical activity by NFS-60 cells was studied in accordance with WHO internation al standard for G-CSF.Methods MTT method was adopted.R esults The chomosone number of NFS-60 cell was 39, about 1×105 cells/ml to 1×107 cells/ml,the dying color showed gradient when the NFS-60 c ells was dyed by MTT,the method(4,4) was adopted in the determination of rhG-CS F biological activity,the average FL% of potency was 13.560% for single exprimen t,and the CV of inter-assay and intra-assay was lower than 10% and 10.109%,respectively.Conclusion method(4,4) can be us ed in the determination of rhG-CSF biological activity,and the results can guid e the study and the manufacture of rhG-CSF effectively.

Objective: To explore the turnover and treament of postoperative remainder of giant nonfunctioning pituitary adenoma with suprasellar extension(SSE). Methods: The clinical data of 68 cases suffering from giant nonfunctioning pituitary adenoma with suprasellar extension(SSE)admitted into our department were retrospectively analyzed.These patients underwent primary transsphenoidal surgery. Results: Twenty cases had SSE adenomas totally removed(20.6%).In other 48 cases(79.34%),SSE residues were shown in MRI recheck at one day after surgery.After 3 months,the 3rd MRI scanning was performed only to find that tumor residues descended to sellar floor in 21 cases,into intrasella in 8 cases,and down to the level of stalk hypophysial and the entrance to the sella in 3 cases.All of Patients with residual tumors received retranssphenoidal resection(the total removal rate of desending SSE residues was 96.9%).There were 2 cases with adenoma residues with slight descending.Obvious SSE adenomas were treated with transtranial approach.The twelve cases with small SSE residues were consecutively observed and two of them received gamma knife treatment because of unobvious postoperative visual improvement.The surgical mortality was 0%.There was no death during follow up in all of these patients.There were no cases with rhinorrhea.meningitis or visual deterioration.Two patients had supradiaphragmatic bleeding detected by routine postoperative CT. Conclusion: Staged surgery with two or multiple transsphenoidal resections is an appropriate treatment for giant nonfunctioning pituitary adenoma with supresellar extension(SSE),with few complications.Futher study is warranted to investigate the growth pattern of pituitary adenoma.

Purpose Both the working standard and corresponding sample(GRAN75)were first calibrated by WHO international standard for G-CSF.Methods MTT method by NFS-60 cells was used. The results were calculated by (4,4)method.Results Three batchs working standards were prepared,two batchs were freeze-dry and the prescription was same as WHO international standard for G-CSF,one batch was injection and the prescription was same as corresponding sample(GRAN75).The biological potency and the FL% of average potency were 3.062×106 、4.276×106IU/ampoule、1.635×107IU/ml and 5.529%、4.291%、4.244% for working standard, and 1.880×107IU/ml and 5.175% for corresponding sample,respectively.Conclusion The working standard which calibrated could be used as working standard in the measurement of rhG-CSF biological activity.

Acupuncture anesthesia is a technique by partially or completely replacing anesthetics with acupuncture in surgery based on the traditional acupuncture analgesia mechanism.It emerged in the 1950s,went viral in the 1970s and then gradually fell into decline.In the recent years,this technique has regained attention and further research.Acupuncture anesthesia can be classified as either pure acupuncture anesthesia or acupuncture-medication combined anesthesia.To expand the application of this technique,a patient with non-ST elevation acute coronary syndrome in urgent need of percutaneous coronary intervention (PCI) received pure acupuncture anesthesia because of an allergy to lidocaine,and the operation went successfully.This is the first time that pure acupuncture anesthesia and coronary arteriography were combined,which is of great significance in further study and development of acupuncture anesthesia.
