The original teaching of clinical pharmacy for stomatology course did not let students aware of the importance of drugs in the treatment of oral diseases. The original teaching framework was rearranged:decentralizing knowledge of oral diseased related clinical pharmacy into several mod-ules;setting general knowledge into the oral basic medical module;adding the practice of visiting the pharmacy and manufacturing laboratory. Teaching process was closely combined with clinics and was integrated with disease-centered oral medicine curriculum integration system. Students responded that the teaching effect was better. The rearranged teaching method can enhance students' attention on drug treatment for oral diseases,improve their ability of clinical medication and promote the teaching quality.

Objective To investigate various types and quantities of fetal cells getting into peripheral blood of pregnant women and immune status related to pregnancy induced hypertension syndrome (PIH) and analyze the etiology of PIH.Methods (1) Three markers of fetal nucleated red blood cells (fNRBCs) in normal pregnant women(n=43)and PIH patients (n=39)were measured by flow cytometry: CD71,HbF/iAg and HbF/CA.(2)We detected the levels of sub-groups of lymphocytes and some plasma cytokines.such as TNF-α and IL-6.The blood samples were from normal pregnant subjects and patients of PIH.Results In the peripheral blood of patients of PIH and normal pregnant subjects,(1) The quantities of fetal cells using three different methods in PIH [6.56(11.37)%、0.09(0.16)%、0.06(0.11)%]were significantly different from normal pregnant subjects[1.58(3.35)%、0.04(0.08)%、0.02(0.06)%],Z= -5.31,-2.97,-4.13 respectively,P＜0.01.(2)Except CD8,the levels of CD3 (76.4±8.5)%,CD4(42.6±6.4)%,CD4/CD8(1.5±0.4)%,CD19(10.5±3.9)%,CD16/CD56 (12.2±7.7)%,TNF-α (1.4 ±0.6)μg/L and IL-6(89.6±12.9)μg/L in PIH were significantly different from normal pregnant subjects[CD3(70.4±8.3)%,CD4(35.3±6.9)%,CD4/CD8(1.2±0.4)%,CD19(8.2±2.8)%,CD16/CD56(20.5±8.9)%,TNF-α(0.5±0.2)μg/L and IL-6(22.0±5.7)μg/L,respectively,P＜0.001].There were no significant differences observed in the level of CD8(P＞0.05).Conclusion The increment of fNRBCs getting into peripheral blood of pregnant women and associated immune status were implicated in the development of PIH.

OBJECTIVETo evaluate clinical application and clinical outcomes of free flap pedicled with supracarpal cutaneous branch of ulnar artery in repairing of finger replantation with skin defect.

METHODSFrom April 2007 to March 2013,25 patients affected by finger amputation with skin defect were replanted and repaired by free flap pedicled with supracarpal cutaneous branch of ulnar artery. Among them, 18 patients were male and 7 were female,with an average age of 31.5 years old (ranged 16 to 58). The time of trauma to admission ranged from 45 to 210 min (averaged 105). Fifteen patients were complete separted, and 10 patients were non-complete separated. The area of flaps ranged from 3.5 cm x 2.0 cm to 4.5 cm x 3.0 cm, and the vessels were anastomosed through end-to-end. The functional evaluation standard of finger replantation was used to evaluate the postoperative function.

RESULTSTwenty-four cases were finally survived. Two flaps occurred vascular crisisin within 48 h after operation, one of which was survived after anti-vasospasm treatment and changing dressing,another was replanted finger for failed to survive. One had infection and healed after changing dressing. Twenty-four cases were followed up from 3 to 38 months with an average of 16.5 months. The appearance and texture of flaps were satisfactory, and the superficial senses of pain and touch were recovered,and two-point discrimination was 5.5 to 11 mm (averaged 7.4 mm). According to functional evaluation standard finger replantationissued by Hand Surgery Association of Chinese Medical Association, 8 cases got excellent results, 14 good and 2 poor.

CONCLUSIONThe free flap pedicled with supracarpal cutaneous branch of ulnar artery can be used in complex finger replantation with skin and vessels defect, which can extend operation indications, recover function and appearance for maximum.

Objective To explore the effects of acupuncture and individualized occupational therapy on the rehabilitation of patients with unilateral spatial neglect ( USN ) after stroke.Methods Stroke patients with hemiplegia were evaluated by neuropsychological tests,including line bisection,a cancellation test,clock drawing,and figure and shape copying.Sixty-nine right hemispheric stroke patients identified with USN were randomly assigned to 3 groups:20 patients as a control group received conventional rehabilitation therapy ; another 22 patients as an occupational group received type-specific individualized occupational therapy combined with conventional rehabilitation therapy; the remaining 23 patients as an acupuncture combined with occupational therapy group received acupuncture in addition to both conventional rehabilitation therapy and occupational therapy.These three groups were evaluated with neuropsychological tests and the modified Barthel index (MBI) before and after treatment.Results ①MBI scores in the occupational therapy group and the combined group were significantly higher after treatment,but no significant difference was observed in the control group.②The increased MBI scores in the combined and occupational groups were higher than those in the control group.At the same time the increase in MBI scores in the combined group was significantly greater than in the occupational therapy group.③The assessment results with both line bisection and cancellation tests in all three groups were significantly different after treatment.The line bisection results in the occupational therapy group and the combined group were significantly better than in the control group.The cancellation test results in the combined group were significantly better than in the control group.Conclusion These findings show that acupuncture combined with occupational therapy can have a positive effect on neglect recovery and greatly improve the daily life of USN patients.

Objective To characterize contemporary electrographic neonatal seizures by video electroencephalogram (VEEG) and to assess the value and the limitations of two-channel (C3-C4/T3-T4) amplitude-integrated electroencephalogram (aEEG) plus original EEG signals used to diagnose neonatal seizure with video EEG as a golden standard.Methods Sixty-six neonates admitted to Children's Hospital of Fudan University from January 2011 to July 2011 with clinical or suspected clinical seizure were investigated and bedside VEEG were recorded for more than 3 hours.VEEG signals were transformed into three kinds of aEEG signals by Galileo NT PMS software:one-channel aEEG (C3-C4),one-channel aEEG (C3-C4) plus original EEG,two-channel aEEG (C3-C4/T3-T4) plus original EEG.Electrical seizure activity on VEEG was signed out with respect to its occurrence,duration and localization of seizure onset; while aEEG seizure was recorded only with its occurrence.The relationship between aEEG and VEEG was analyzed by Spearman analysis.The value and the limitations of aEEG to diagnose neonatal seizure were evaluated by sensitivity,specificity,positive predictive value and negative predictive value.Results A total of 62 traces were suitable for analysis.(1) VEEG showed 39 seizure activities,among which 8 status epilepticus; and the rest 31 neonates had 352 non-status epilepticus electrical seizures,79.3％ (279/352) of which occurred over the centrotemporal region.(2) Eight cases with status epilepticus on VEEG were all diagnosed as status epilepticus on aEEG.For non-status epilepticus electrical seizures,the sensitivity of aEEG for detection of electrical seizures was as followed:49.1％ (173/352) for one-channel aEEG,54.5 ％ (192/352) for one-channel aEEG plus original EEG,81.2％ (286/353) for two-channel aEEG plus original EEG.Results from one-channel aEEG,one-channel aEEG plus original EEG and two-channel aEEG plus original EEG were all related to VEEG (ρ =0.790,0.907 and 0.953,respectively,P＜ 0.01).(3) Sensitivity of seizure detection was 66.7％ (26/39,95％ CI:0.62-0.81) for one-channel aEEG,74.4％(29/39,95％ CI:0.78-0.96) for one-channel aEEG(C3-C4) plus original EEG and 89.7％ (35/39,95％ CI:0.89-1.00) for two-channel aEEG(C3-C4/T3-T4) plus original EEG.Conclusions VEEG might help aEEG in diagnosis of neonatal seizure.two-channel aEEG (C3-C4/T3-T4) plus original EEG could significantly increase the sensitivity of neonatal seizures indentification.

Objective To investigate the regional left ventricular function after mitral valve replacement with and without chordal preservation by strain rate imaging. Methods A total of 55 patients undergoing mitral valve replacement were enrolled. Twenty underwent complete excision of the subvalvular apparatus (group A), 20 preserved the posterior chordopapillary apparatus only (group B) and the other 15 underwent total chordal preservation (group C). Systolic peak strain rate (SRs) were measured preoperatively, at 7-10 days and 3 months after operation. Results Before operation, SRs had no differences between different segments of the left ventricular in each group (F=0.37, 0.74, 0.90, all P>0.05). At 7-10 days after operation, SRs in the most segments of left ventricular were signiifcantly lower than those of before operation (F=3.91, 8.12, 7.57, all P<0.05). At 3 months after operation, SRs in some segments of left ventricular were signiifcantly higher than those of preoperation in each group (t=2.12, 3.19, 3.25, 2.08, 2.78, 4.79, 2.81, 2.58, 2.87, 1.60, 0.34, 1.04, 0.73, 0.70, 1.68, all P<0.05). SRs had no signiifcant differences between each segment of left ventricular in group C (F=1.76, P>0.05). By contrast, SRs in some segments of left ventricular were different from those of other segments in group A and group B (F=17.8, 8.52, both P<0.05). Conclusion Comparing to conventional mitral valve replacement and mitral valve replacement with preservation of posterior subvalvular apparatus, mitral valve replacement with preservation of total subvalvular apparatus makes the papiltary function preserved completely, which are beneifcial for the motor coordination of left ventricular wall and the recovery of regional left ventricular function.

Objective To discuss the feasibility and short-term clinical effectiveness of DSA-guided percutaneous vertebroplasty (PVP) for the treatment of painful osteoblastic metastatic spinal lesions. Methods During the period from Jan. 2010 to Dec. 2011 at authors’ hospital PVP was carried out in 23 patients with osteoblastic spinal metastases (34 lesions in total). Coexisting osteoblastic pathological fracture was found in twelve patients. The WHO standards, visual analogue scale (VAS) and karnofsky-KPS score were used to evaluate the therapeutic results. Results Technical success was achieved in all patients. All patients were followed up for at least 3 months. Of 20 patients who had complete clinical data, complete remission (CR) was obtained in 6, partial remission (PR) in 10, mild remission (MR) in 3 and no remission (NR) in one. The clinical effectiveness (CR+PR) was 80%. The mean VAS scores dropped from preoperative (7.0 ± 1.6) to (2.2 ± 1.9) at 24 hours after the treatment, and to (2.4 ± 2.1) and (2.5 ± 2.1) at one and three months after the treatment respectively. The mean KPS scores rose from preoperative (76.5 ± 10.4) to (86.5 ± 11.8), (88.0 ± 12.0) and (89.0 ± 10.8) at 24 hours and one, three months after the treatment respectively. Small amount leakage of PMMA was observed in 4 cases (17.4%) with no obvious clinical symptoms. Conclusion DSA-guided PVP is a feasible and effective treatment for painful osteoblastic spinal metastases. This therapy can immediately relieve pain and reinforce spine, besides, it can remarkably improve the living quality and
decrease the incidence of paraplegia.

Objective To evaluate the technique and clinical results of the modular fluted tapered stems for treating periprosthetic femoral fractures in revision hip arthroplasty.Methods From August 2007 to February 2014,fourteen patients (14hips) with periprosthetic femoral fractures underwent revision hip arthroplasty with modular fluted tapered stem.A retrospective analysis was performed involving all patients who were followed-up more than 2 years.The subjects consisted of 4 males and 10 females with mean age of 73.4±6.6 years (range,62-82 years) at the time of revision.All patients were unilateral with 8 left hips and 6 right hips.The status of primary arthroplasty was bipolar hemiarthroplasty in 3 patients and total hip arthroplasty in 11 patients.Nine cases were with cemented stems,5 cases with uncemented stems.The interval from primary hip arthroplasty to revision surgery ranged from 40 to 163 months,with an average of 120.9±31.9 months.Eight cases with Vancouver type B3 periprosthetic femoral fracture were found preoperatively,6 cases with aseptic loosening and bone deficiency occurred periprosthetic femoral fracture during the operation.Based on the Paprosky classification system for femoral bone deficiency:type ⅢA in 8 hips,type ⅢB in 5 hips,type Ⅳ in 1 hip.Both the femoral and the acetabular components were revised in 9 patients.All femoral fractures were treated with cable fixation,and the cortical allograft struts were used to augment femoral bone stock in 7 patients.The patients were followed up at 6 weeks,3 months,6 months,9 months,12 months and annually thereafter.Harris Hip Score System and radiographic examination was used to evaluate the clinical results,including fracture union,implant stability,bone stock,hip joint function and postoperative complications.Results The mean duration of follow-up was 62.1 ±22.2 months (range,30-96 months).The mean times of fracture union were 6.2±2.5 months (range,3-12 months).The Harris Hip Score improved from 29.6± 10.3 preoperatively to 86.3±4.2 postoperatively (t=-21.6,P=0.00).Thirteen cases (93％,13/14) had the stem subsidence of 4.9±2.5 mm (range,0-9 mm).Thirteen cases (93％,13/14) were presented with femoral bony restoration.Two cases showed incorporation of the allograft in 7 patients.One patient developed deep venous thrombosis of lower limbs,and one suffered from subcutaneous hematomas after surgery.There was no infection,aseptic loosening,dislocation or periprosthetic fracture complications at the followup.Conclusion The short-medium term results of the modular fluted tapered prosthesis applied in periprosthetic femoral fractures are encouraging in revision hip arthroplasty.The present technology can provide reliable primary stability and can tolerate minimal subsidence postoperatively.

Objective To explore the change of microRNA let-7b in heat acclimatization/heat stroke rat models and its relation with HSP70,IL-6,TNF-α,TGF-3 and IL-12,and analyze its clinical significance.Methods 60 male rats with almost the same anal temperature,weight,and weeks' age were selected from Laboratory Animal Center in the Second Military Medical University.They were randomly divided into control,heat acclimatization,heat stroke groups averagely.Heat acclimatization/heat stroke rat models were built in hot climate simulated animal tank,blood was collected from cordis apex and serum was separated.Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to test microRNA let-7b in serum,enzyme-linked immunosorbent reaction (ELISA) was to measure the protein level of HSP70,IL-6,TNF-α,TGF-β and IL-12 in serum.Kruskal-Wallis H test was used to analyze quantitative data in the three groups,Spearman rank correlation coefficient was used to reveal relation between two variables in heat stroke group.Results M values of miRNA let-7b in control,heat acclimatization,heat stroke groups were 0.99,1.04 and 1.93 separately,Q values were 0.30,0.25 and 0.44 (x2 =38.95,P＜0.001),separately,with statistical significance.The results of pairwise comparison showed no statistical difference in control and heat acclimatization (P＞0.05),but there were differences in control and heat stroke,heat acclimatization and heat stroke groups statistically (P＜0.05).Spearman correlation analysis showed that in heat stroke group,let-7b was positively related with HSP70,TNF-α and IL-6 (rs =0.579,0.498 and 0.609,P＜0.05) with statistical significance.Conclusion miR let-7b might involve in the pathology of heat stroke,it provided a potential biomarker for monitoring patients in high temperature and humidity clinically.

OBJECTIVE: To investigate effects of antioxidant stress protein heme oxygenase-1 (HO-1) on lipopolysaccharide (LPS)-induced endoplasmic reticulum stress (ERS) of rat hepatocytes. METHODS: The BRL cells (rat hepatocyte cell line) were cultured. The hepatocytes were treated with LPS, LPS+HO-1 siRNA, HO-1 siRNA and PBS solution, respectively. The cell viability was measured by trypan blue exclusion test. The apoptosis cells were detected by the fluorescent dye Hoechst 33258. Expressions of GRP78, CHOP, caspase-12 and HO-1 were detected by Western blotting. RESULTS: LPS caused an increase of HO-1 protein expression of rat hepatocytes in a dose-dependent and time-dependent manner, a up-regulation of GRP78, CHOP and caspase-12, a decrease in cell viability, and an increase in apoptosis rate of hepatocytes. Pretreatment of HO-1 siRNA inhibited the up-regulation of LPS-induced HO-1, however, aggravated ERS and cellular injury. CONCLUSION HO-1 inhibites ERS-mediated cellular injury of rat hepatocytes induced by LPS.
