By using CT, MRI as diagnostic measures for intracerebral granuloma. cysticercosis and tuberculous granuloma were excluded. Using penecillin as control, all cases were treated with Yanzhengxiao capsules. Results demonstrated that the total effective rate in the treatment group was 90%, with a cured rate of 61. 7%, that of the penicillin group. 53. 3% and 26. . 9% respectively with significant difference (P

Objective To investigate the clinical festures and CLCN1 gene mutation screen on a myotonia congenital kindred.Methods The clinical data of 22 patients in the myotonia congenital kindred were analysed. Results There were total 68 people in 5 generations, including 24 patients in 4 generations .Both male and female were suffered. All patientes of this kindred showed myotonia with onset the illness from the infant, and 16 cases accompanied with hypermyotrophy.The levels of creatases and dielectric in serum were normal in all the cases. Spontaneous myotonic electric potential were observed on electromyography( EMG ) in 2 cases.The proband was found in light microscope by biopsy that muscle fibers arranged loosenly , size of them mismatched , transverse striation was unclear and some of them was hyperplasia and hypertrophy. Muscle cells degenerated gently with a few inflammatory cells infiltration. No mutation was found in the whole 23 extrons of CLCN1 gene in the 3 patients.Conclusions This kindred accords with the autosomal dominant heredity form Thomsen's disease. The affected numbers have the typical clinical characteristics. No mutation is found when 23 extrons of CLCN1 gene screened in the patients which indicate the genetic heterogeneity may be exist in this kindred.

Objective To study the abnormalities of motor evoked potentials(MEPs)obtained from obese subjects induced by magnetic stimulation at T12 to L1. Methods A total of 90 healthy subjects without any neuro-muscular system abnormalities were divided into 3 groups according to the body mass index(BMI).The control group consisted of 30 normal somatotype males(BMI<23),while the obese somatotype group(BMI>30)and weight-reduc-ing group(BMI>30)consisted of 30 obese somatotype males,respectively.The subjects in the control group and obese somatotype group maintain their usual lifestyle as before,while those in the weight-reducing group were reques-ted to lose weight by all means.MEPs were induced by using magnetic stimulation of 70%and 90%the output of the stimulator,respectively,at T12 to L1 and recorded from all the anbjcots at the time of admission to the study and one year later. Results At admission,the amplitude and conduction time of MEPs in obese somatotype group and weight-reducing group were significantly different from those in control group(P<0.05),when the magnetic stimula- tion of 70%the stimulator output was employed.but all the indexes were not difierent when 90%the stimulator uot- put were adopted(P>0.05).One year later,the amplitude and conduction time of MEPs in obese somatotype group were significantly different from those in control group and weight-reducing group(P<0.05),but all the indexes were not different within 3 groups when 90%the stimulator output was adopted(P>0.05). Conclusion Supra-maximal magnetic stimulation should be used for recording the MEPs from the obese subjects,or false positive result would be obtained.

Objective:To investigate the effects of down-regulation of Krüppel-like factor 5 (KLF5) on biological functions of rat intestinal epithelial cells IEC-6 in response to ionizing radiation.Methods:Rat intestinal epithelial IEC-6 cells were irradiated with 0, 2, 4, 8, 12, 16 Gy of X-rays and 3 h later the expression of KLF5 in IEC-6 cells was detected by Western blot. IEC-6 cells were irradiated to 12 Gy and 0, 0.5, 1, 2, 3, 5, 7 and 24 h later the expression of KLF5 in IEC-6 cells was detected by Western blot. shRNA sequences targeting rat KLF5 gene were designed, synthesized and inserted into the lentiviral vector. The recombinant lentiviral vectors were packaged in human embryonic kidney 293T cells, and the lentivirus titers were determined. IEC-6 cells were infected with the recombinant lentivirus, and the transfection efficiency was observed under fluorescence microscope. Real-time PCR and Western blot were used to detect the expressions of KLF5 mRNA and protein in the transfected cells 72 h post transfection. The consequent experiments included four groups: negative control group, shKLF5 group, radiation group and radiation + shKLF5 group. The cell viability was observed in KLF5 silencing cells irradiated with 8 Gy by using CCK-8 assay. The cell cycle distribution and apoptosis were detected in KLF5 silencing cells irradiated with 8 Gy by flow cytometry. Immunofluorescence staining was applied to visualize the γ-H2AX foci in nucleus of KLF5 silencing cells irradiated with 2 Gy.Results:The expression of KLF5 increased with the different doses. The expression of KLF5 increased first, then decreased and peaked at 5 h post-irradiation with 12 Gy. KLF5 shRNA lentiviral vectors were successfully constructed. The mRNA and protein level of KLF5 were down-regulated in recombinant lentivirus transfected IEC-6 cells 72 h after transfection. Knockdown of KLF5 markedly induced G 2/M phase arrest ( t=11.56, P<0.05), proliferation inhibition, more apoptosis rate [radiation group: (7.42±0.49)%, radiation + shKLF5 group: (12.49±0.63)%, t=10.98, P<0.05], and more γ-H2AX foci in nucleus post-irradiation than negative control ( t=22.07, 23.89, 11.24, 59.97, 20.85, P<0.05). Conclusions:The KLF5 knockdown intestinal epithelial cell line was successfully established. The down-regulation of KLF5 expression could induce cell arrest at G 2/M, suppress the proliferation of irradiated cells and improve the cell apoptosis, enhance DNA double strand breaks and prolong DNA damage repair.

Novel therapeutic approaches targeting key genes and regulatory molecules of hepato-cellular carcinoma(HCC)have gradually been carried out in clinical practice.Hypoxia-inducible factor(HIF),as a critical factor for hepatocellular carcinoma cells to adapt to the hypoxic microenvi-ronment,mediates changes in the transcription of many genes.HIF has a wide range of target genes and can promote metabolic reprogramming,angiogenesis,invasion and metastasis,and immune es-cape of cancer cells by regulating various signaling pathways.Hypoxia-inducible factor 1α(HIF-1α),as the main member of the HIF family,can provide new ideas and insights for exploring potential tar-gets for HCC treatment.

We think that all the methods of puncturing into the skin to prevent and treat diseases are belong to acupuncture science. In spite of its basic theory of meridian and acupoint, anatomy and physiology have been important parts of modern acupuncture science. "Dry needling", however, is limited to trigger point theory. As for the positions, acupuncture is applied mainly at acupoints, involving in skin, muscles, tendons, vessels and nerves; while "dry needling" is used mostly at muscles. The needles of acupuncture are in various lengths and diameters and its manipulations are abundant, including the traditional skills and the achievements of modern science and technology research, such as electroacupuncture. It is different from the "dry needling" with the single tool and manipulation. Thus, acupuncture is suitable for a large range of syndromes, but "dry needling" is mainly for fascia muscularis pain and other related disorders. The acupuncturists need to embrace Chinese and western medicine, which is more rigorous than the training for "dry needling" practitioners. Based on the above reasons, we consider "dry needling" as part of acupuncture science, and it is a method during the modern development of traditional acupuncture.
