ObjectiveToinvestigate the effect of different needling methods on ischemic stroke, for seeking the effective treatment for stroke.MethodBy following the randomized controlled principle, the sixty enrolled patients were randomized into an electroacupuncture groupand an acupuncture group, 30 cases in each group. The two groups were both intervened by needling treatment in addition to the conventional internal medicine management, electroacupuncture for the electroacupuncture group,and ordinary acupuncture for theacupuncture group. The Neuropathy Disability Scale (NDS), Fugl-Meyer Assessment (FMA), and Barthel Index (BI) were adopted for evaluation and comparison.ResultThe NDS, FMA, and BI scores were significantly changed after treatment in both groups (P<0.01); there were significant differencesin comparing FMA and BI scores between the two groups (P<0.05).ConclusionElectroacupuncture can produce a more significant efficacy in treating ischemic stroke compared with ordinary acupuncture, electroacupunctureis also better than ordinary acupuncture in improving the neural deficit.

Objective:To provide some experimental basis of cell biomechanics for clinic treatment of massage by exploring synthesis and liberation of NO and IL-1? from fascia tissue cells of rat under pressure stimulation in vitro.Methods:Fascia tissue cells of rat were cultured in vitro.After morphological identi cation,50kPa pressure was forced on these cells,then the contents of NO and IL-1? in culture medium were detected.Results:The fascia tissue cells are mainly made up of broblast cells.The contents of NO and IL-1? in culture medium were both increased signi cantly under pressure stress.Conclusion:Fascia tissue cells can receive the mechanical stimulation,and transform the mechanical signals into biological signals.The reaction to mechanical stimulation may be one of the cell biomechanical principles of massage.

Objective:To determine the expression level of bone morphogenetic proteins-4 (BMP-4) and the relationship between the expression of BMP-4 and the clinical/pathological parameters in patients with gastric cancer. Methods:Using im-munohistochemical staining technique ,expressions of BMP-4 were investigated in different tissues from 90 gastric cancer specimens and 30 specimens from normal gastric mucosa as control. ResultS:The positive rate of BMP-4 was 23. 3% (21/90) in gastric cancer and 3. 3% (1/30) in normal gastric mucosa. The expression of BMP-4 in gastric cancer was closely related with locus, serosa infiltration,cell differentiation and lymph node metastasis (P

BACKGROUND: The biological behaviors of preadipocytes in adipose tissue of young animals have been closely linked to the onset and prevention and treatment of obesity. Observing mechanical oscillation effects on biomechanical behaviors of preadipocytes using biomechanical stimuli would provide more direct experimental evidence for treatment of simple obesity using manipulation and massage therapy.OBJECTIVE: Different frequencies of mechanical force stimulation were performed on preadipocytes from young rats cultured in vitro to observe the changes in cell viability, proliferation, and apoptosis.METHODS: Preadipocytes from SD young rats were in vitro cultured. Following identification, preadipocytes were dynamically, mechanically stimulated through the use of constant temperature oscillator. According to different treatment frequencies, three groups were set: 0 Hz (blank control), 1.5 Hz, and 3 Hz. A 30-minute oscillation, once every 12 hours, total 3 days, was performed in each group. Following dynamic mechanical stimulation, cell viability, proliferation, and apoptosis in young rats were observed. RESULTS AND CONCLUSION: In the initial stage of culture,cells exhibited the morphology similar to fibroblasts. After oil red O staining, red particles appeared in the cells, indicating that the young mouse cells cultured in vitro were preadipocytes. With stimulation of oscillation force, the viability and proliferation of preadipocytes were significantly inhibited (P < 0.05 or P < 0.01). There wasno significant difference in effects of mechanical oscillation on preadipocyte apoptosis between 0 Hz and 1.5 Hz, 3 Hz groups (P > 0.05). These findings indicate that thecell biological mechanism underlying preventing simple obesity in adolescents is to inhibit the viability and proliferation of preadipocytes

Objective To observe the characteristics offundus autofluorescence (FAF) in patients with polypoidal choroidal vasculopathy (PCV) before and after intravitreal ranibizumab injections.Methods A retrospective case series.Seventeen patients (17 eyes) including 11 males and 6 females were enrolled in this study.Best corrected visual acuity (BCVA),FAF and indocyanine green angiography examination were performed on all eyes.The eyes were divided into hypo-autofluorescence group (8 eyes) and mixed autofluorescence group (9 eyes) according to the fluorescence degree.There was no differences of BCVA between two groups (t=2.403,P=0.072).A11 eyes received monthly intravitreal ranibizumab injections for 3 months followed by an as-needed reinjection schedule.All eyes were followed up for 12 months.FAF was performed at the 3rd,6th and 12th month after first treatment.The changes of FAF characteristics and BCVA before and after treatment were observed.Results Before the treatment,the PCV lesions showed two distinct FAF patterns:the confluent hypo-autofluorescence at the polypoidal lesions and the granular hypo-autofluorescence at branching choroidal vascular networks (BVN).During the treatment,the abnormal FAF area of the whole lesions in all eyes reduced and gradually returned to normal.At the 3rd month after treatment,the central hypo-autofluorescence of polyps was surrounded by a hyper-autofluorescence ring,and with time,the ring was weakened or eliminated.However,all the hypo-autofluorescence findings in BVN at baseline were unchanged during the follow-up period.There was no significant differences in BCVA between hypo-autofluorescence group and hyper-autofluorescence group at different follow-up times (t=2.674,2.862,2.250;P=0.058,0.052,0.081).At final follow-up,5 eyes (62.5％) in hypo-autofluorescence group and 3 eyes (33.3％)in hyper-autofluorescence group had increased BCVA,the different was not significant (P=0.347).Conclusions Before the treatment,there were the central hypo-autofluorescence of polyps and circumferential hypo-autofluorescence ring or confluent hypo-autofluorescence.After the treatment,the autofluorescence of polyps increased and then gradually returned to normal.

Objective To construct an eukaryotic expression vector of human telomerase reverso transcriptase (hTERT) gene specific shRNA, and investigate the effect of pshRNA-hTERT combined with γ-irradiation on telomerase activity and DNA damage. Methods The recombinant expression plasmid pshRNA-hTERT was constructed and transfected into Hep-2 cells. The telomerase activity was examined by the PCR-hased telomeric repeat amplification protocol (TRAP). DNA single-stranded break (SSB) and the DNA double-stranded break (DSB) were detected by Comet assay. The xenograft model of human laryngeal carcinoma with the same genetic background and different radiosensitivity (Hep-2 and Hep-2R) was established in nude mice. The mixture of pshRNA-hTERT and liposome was injected to the transplanted tumor to observe the inhibition of the tumor growth. The cell apoptosis was detected by TUNEL. The hTERT protein expression was determined by streptavidin-peroxidase conjugated method (AP). Results Recombinant expression plasmid pshRNA-hTERT was successfully constructed and transfected into Hep-2 cells. The hTERT expression inhibition rate reached 60.78 %. pshRNA-hTERT not only inhibited telomerase activity of Hep-2 inehiding the increase of telomerase activity induced by γ-irradiation, but also inhibited the repair of the SSB and DSB induced by irradiation in the human laryngeal carcinoma xenograft in nude mice with the same genetic background and different radiosensitivity. The pshRNA-hTERT combined with γ-irradiation could inhibit the growth of transplanted tumor (Hep-2: EPO = 1.79; Hep-2R: EPO = 2.01) with reduced telomerase activity and hTERT protein expression. Conclusions The eukaryotic expression vector pshRNA-hTERT could enhance the radiosensitivity of Hep-2 cells in vitro and the human laryngeal carcinoma xenograft in nude mice which had the same genetic background with different radiosensitivity.

Fang's scalp acupuncture is mainly used in the treatment of nervous system diseases, bone and joint pain and mental diseases. It has significant effect on the early stage recovery stage and complications of post-stroke hemiplegia. The selection of acupoint is basically the same in improving patients with neurological impairment and dyskinesia, but differenct in the selection of acupoints in the treatment of complications. In recent years, it has been widely used in the treatment of children with attention deficit hyperactivity disorder and Tourette's syndrome. Fang's scalp acupuncture method was formed quite early with relatively complete theoretical system, but its clinical application is relatively insufficient. There exist some problems such as failing to reflect the theory of viscera and meridians in acupoint selection, the theory of acupoint selection by projection of cerebral cortex function, which needs to be proved further, the operation requirements are strict while the methods and practice of researchers are are differenct, and some clinical research design is not rigorous,etc.

The integrated curriculums of basic medicine in Shanxi Medical University are as follows: nine basic medical courses were integrated into 10 medical modules, with additional training including PBL and TBL case discussion, clinical clerkship, flipped classroom and other non-integrated subjects etc. In order to assess the interest of students for integrated curriculum, their intrinsic motivation, as well as their comprehension and application of medical knowledge, we gave anonymous questionnaire to 149 students, 16 teachers in basic medicine, and 10 teachers in clinical medicine. Results showed that more than 90% students were willing to take the integrated curriculum and participate in PBL and TBL case discussion, and students who were unwilling to take the curriculum were less than 10%, they thought that the knowledge of new curriculum system was incoherent. The proportion of students from higher grade who were unwilling to participate in the flipped classroom was increased from 6.7% to 95.0%. Most of the teachers both in basic and clinic medicine believed that new curriculum system was helpful for students to comprehend basic medical knowledge and strengthen their discriminating ability, but did not function in improving students' practical ability. In the further reform on teaching, details like the coherence of knowledge and the content selected when self-studying should be improved.

OBJECTIVE: To investigate the efficacy and safety of the bladder training in male patients before urinary catheter removal after mid-low rectal cancer surgery. METHODS: This was a prospective, open, randomized controlled study. INCLUSION CRITERIA: male patients; pathologically diagnosed as mid-low rectal adenocarcinoma; distance from tumor lower edge to anal margin ≤10 cm; standard radical surgery for rectal cancer, including intestinal resection and regional lymph node dissection. EXCLUSION CRITERIA: previous history of benign prostatic hyperplasia or history of prostate surgery; bladder dysfunction such as dysuria and urinary retention before surgery; local resection of rectal tumor or extended resection. According to the above criteria, 92 patients who underwent colorectal surgery at the Union Hospital of Fujian Medical University from June to December 2016 were prospectively included. The patients were randomly divided into bladder training group (n=43) and bladder non-training group (n=49) according to the random number table method. The study was approved by the Ethics Committee of the Union Hospital of Fujian Medical University (ethical approval number: 2016KY005) and registered with the China Clinical Trial Registration Center (ChiCTR) (registration No.ChiCTR-IOR-16007995). The implementation of patient's treatment measures, the data collection and analysis were based on the three-blind principle, using envelopes for distribution concealment. In the bladder training group, bladder training was routinely performed from the first day after operation to catheter removal, and in bladder non-training group the catheter was kept open till its removal. The catheter was removed in the early morning at the 5th day after surgery, and the spontaneous urine output was recorded and the residual urine volume of the bladder was measured after the first urination. The international prostate symptom score (IPSS) was applied to evaluate the patient's urinary function before and after surgery. RESULTS: The age of whole group was (58.6±10.9) years old, the body mass index was (22.4±2.7) kg/m , and the distance from tumor lower edge to anal margin was (6.5±1.9) cm. The baseline data, such as age, body mass index, distance from tumor lower edge to anal margin, preoperative IPSS score, preoperative bladder residual urine volume, neoadjuvant radiotherapy and chemotherapy, preventive ileostomy and surgical procedure were not significantly different between two groups (all P>0.05). There was no significant difference in IPSS scores evaluated at the second day (3.6±4.0 vs. 3.5±3.4, t=0.128, P=0.899) and one month (3.7±2.9 vs. 3.0±3.1, t=1.113, P=0.269) after catheter removal between the bladder training group and bladder non-training group. No significant difference in the postoperative residual urine volume of bladder (media 44 ml vs. 24 ml, Z=-1.466, P=0.143), the first spontaneous urination volume (median 200 ml vs. 150 ml, Z=-1.228, P=0.219) after catheter removal, and postoperative hospital stay [(8.2±4.5) days vs. (9.1±5.5) days, t=-0.805, P=0.423] was found. Urinary infection rate was 20.9%(9/43) in the training group, which was even higher than 8.2%(4/49) in the non-training group, but the difference was not significant(χ²=3.077, P=0.079). No patient needed re-catheterization in either group. CONCLUSIONS The routine bladder training after mid-low rectal cancer surgery does not improve the urinary function, and can not reduce the residual urine volume of bladder after catheter removal. This routine clinical practice is not helpful for the bladder function recovery after rectal cancer surgery.
