Hypophosphatasia (HPP) is caused by loss-of-function mutation(s) of the gene that encodes the tissue-nonspecific isoenzyme of alkaline phosphatase (TNSALP). Its manifestations are variable, including impaired skeletal mineralization, altered calcium and phosphate metabolism, recurrent fractures, pain, impaired mobility, premature tooth loss, developmental delay, and seizures.There are different attempts for HPP.Asfotase alfa (Strensiq?), is a bone-targeted recombinant TNSALP which has shown significant improvements in morbidity and mortality in patients with perinatal and infantile hypophosphatasia, and it can improve growth, mobility function and quality of life.This enzyme replacement therapy has generally been well-tolerated, with most adverse reactions being mild-to-moderate in nature.This article reviews recent advances in the treatment of the disease.

Prostate cancer is the most prevalent malignancies in elderly men. At present, gene therapy is the most po-tential treatment for late-stage prostate cancer. However, virus vector or nonvirus vector are less safety, weaker targeting function and higher immunogenic. Ultrasound microcapsular contrast agent as a drug transporter is a new type of disease tar-geted treatment strategies. It has provided a high-targeted, an effective and a safety gene therapy for prostate cancer, and brings a new hope for late-stage prostate cancer patients. This article aims to summarize the recent progress in using the mi-crobubble technology in prostate cancer.

Objective To explore the effect of FTY720 on human hepatocellular carcinoma cell line HepG-2 of invasion ability. Methods HepG-2 cells were cultured,and divided into 4 groups,namely control and FTY720 (0.05 g/ml,0.10 g/ml,0.15 g/ml) groups.The cell invasion ability was observed by the cell invasion assay.mRNA expression of MMP-2,MMP-9 was measured by RT-PCR.MMP-2,MMP-9 protein expression was measured by ELISA method.Results The invasive ability of cancer cells in each group significantly weaken,with the FTY720 concentration increased.The number of control group was (110±3)(P<0.05),the number of O.05 g/ml FRY720 treatment group cells was (74±4),while the number of cells of O.10 g/ml,0.15 g/ml the drug treated group,Was (42±3),(25±5)(P<0.01).Compared with control group,the MMP-2,MMP-9 expression of different concentrations of FTY720 groups decreased significantly (P<0.05).As the expression of FTY720 concentration increased,the MMP-2,MMP-9 expression decreased (P<0.01).Compared with control group,the MMP-2,MMP-9 protein expression of different concentrations of FTY720 groups decreased significantly (P<0.05), but the protein expression and concentration of FTY720 is inversely proportional in a certain range. Conclusion The invasive ability of HepG-2 cells can be inhibited by FTY720,and with FTY720 concentration increased,the invasive ability decreased gradually.One of the mechanisms may be related to reduce the MMP-2,MMP-9 protein and gene expression.

Objective:To observe the effect of Chinese herbal fumigation combined with three-step tuina manipulation on concentration of endothelin (ET) and calcitonin gene-related peptide (CGRP) and vertigo in patients with vertebral artery cervical spondylosis (VACS).
Methods:A total of 120 eligible cases were randomly allocated into an observation group and a control group, 60 in each group. Cases in the observation group were treated with Chinese herbal fumigation combined with three-step tuina manipulation, whereas cases in the control group were treated with oral Flunarizine Hydrochloride Capsules.
Results: After treatment, vertigo in both groups was alleviated; there were intra-group significant differences in ET decrease and CGRP increase (P<0.01, P<0.05);and there were also inter-group significant differences (both P<0.05).
Conclusion: Chinese herbal fumigation combined with three-step tuina manipulation can regulate the levels of ET and CGRP and improve vertigo in patients with VACS. Its therapeutic efficacy is superior to oral Flunarizine Hydrochloride Capsules.

Objective To investigate the anterior trans-injured vertebral short segment limited fixation and fusion in treating thoracic and lumbar spinal tuberculosis.Methods One hundred and three patients with spinal tuberculosis from 2010 to 2012 were operated by trans-anterior approach(trans-thoracic above thoracic spine 12,trans-retroperitoneal below waist spine 1)tuberculosis focus clearance and spinal canal decompression,intervertebral bone graft of vertebral structure,and short segment internal fixation for residual disease spine.Results The nerve function of the patients was effectively improved after surgery,and the imaging re-sults showed that the average lesion kyphosis angle was significantly decreased(P <0.05).The postoperative follow-up found that the bone graft was fused after half a year,and the average local kyphosis angle was still 13°,which had no obvious change compared with that after operation.In addition,the internal fixation position had no looseness and fracture,the grafted bone had no displace-ment and detachment,the four limbs movement was normal without local percussion pain or tenderness.Conclusion The anterior trans-injured vertebral short segment limited fixation and fusion has the satisfactory short term clinical efficacy in the treatment of thoracic and lumbar spinal tuberculosis.

Objective To introduce a new surgical method of reconstructing A ch illes tendon by transfer of the soleus tendon flap. Methods The method was desig ned on the basis of the anatomical characteristics of the superficial muscles as sociated with Achilles tendon. It was applied to treat 12 patients with Achilles tendon defects. These patients were followed up for 0.5 to 6 years (average 39 months). Results The curative effect of the method were assessed according to Ar ner-Lindholms evaluation criteria. 9 cases were rated as excellent, 2 fine an d 1 poor, with the total excellent and fine rate being 92%. Conclusions ①Misdi agnosis and improper initial treatment are the major causes of Achilles tendon d efects. ②Systematic training after operation is very important for good curativ e effects. ③The method mentioned above brings about less trauma, less negative effects on blood supply to Achilles tendon, and good healing after operation.

Objective To study Baizhu's inhibitory effect on S180 sarcoma growth and its effect on Bcl-2 expression in tumor-transfected mice. Methods S180 cells were subcutaneously injected into 60 healthy Kunming mice. Meanwhile the mice were dealt with MTX or Baizhu, separately; the weight of tumor was measured in the following two weeks; the expression of Bcl-2 was detected by RT-PCR. Results The tumor's weight in Baizhu group was lower than that in model group, but higher than in MTX group (P<0.05), but Baizhu's inhibition was not associated with its dose (P>0.05), and Baizhu's rate of tumor growth inhibition was lower than that of MTX. Compared with that in control group, Bcl-2 expression was lower in Baizhu group obviously. Conclusion Baizhu can inhibit tumor growth and serve as an adjuvant drug in tumor therapy.

The aim is to explore a teaching-centered management system to suit the development of clinical medicine education for international students by setting the educational aim and making training plans in combination with the present condition of the university.All the aspects of teaching such as the establishment of the teaching rules,training of the teachers,reform in teaching,teaching material as well as the teaching and student management and the service in the dorm are strengthened,so as to ensure the steady development of the foreign students education.

Teaching the foreign students clinical medicine in English in the earlier period of foreign students education has played a vital role but also has such problems as teachers,difficulties in the later teaching and so on.Through practice we find that it is necessary to transit the mode from teaching in English to bilingual education,and finally teaching in Chinese in the internship to conform with the present medical foreign students education situation.Therefore ability of teaching in English and proficiency in Chinese are needed to improved as soon as possible.

Objective To evaluate the vestibular function in patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Methods Seventeen CADASIL patients were recruited in the present study and 17 healthy volunteers served as control subjects. Electronystagmogram examinations including gaze nystagmus test, spontaneous nystagmus test, saccade test, pursuit test, optokinetic nystagmus test and caloric test were performed in the subjects. Results Neither patients nor controls had gaze nystagmus or spontaneous nystagmus. There was no difference in the latency and velocity of saccade movement between patients and controls. The accuracy of the saccade movement, the accuracy in leftward saccade, was significantly lower in CADASIL group compared with controls. The pursuit movement gains was also significantly lower in CADASIL group than in control group(G_L:0.79±0.08, G_R:0.76±0.12)(t=-3.739、-2.911,P <0.05) compared with controls(G_L:0.87±0.04, G_R:0.86±0.06).The optokinetic nystagmus gains were significantly decreased in CADASIL group(G_L:0.79±0.17,G_R:0.78±0.18)(t=-2.342、-2.335,P<0.05) compared with controls(G_L:0.90±0.08,G_R:0.89±0.09). The caloric test was performed in one CADASIL patient and the result revealed an incomplete fixing inhibition. CADASIL group was further divided into normal subgroup and abnormal subgroup based on the pursuit curve. The comparison between those two subgroups demonstrated a significant correlation between the pursuit movement and the symptoms of vertigo or dizziness(P<0.05). Conclusions The central vestibular function is impaired in CADASIL patients and the abnormal vestibular function is related to the symptom of vertigo or dizziness in CADASIL patients.
