Objective To evaluate the effects of TENS on metatarsus plantar flexion and inversion in stroke patients,and to explore its mechanism.Methods Thirty-two stroke patients with gastrocnemius spasticity were randomly divided into a control group (n=16) and a TENS group (n=16).All patients were treated with foot sup- ports,neurodevelopmental and manipulation therapies.In addition,the TENS group received TENS on the anterior tibialis,peroneus longus and brevis muscles.All patients were assessed in terms of their Chinese stroke scale(CSS) and H reflex scores before and after therapy.Results Compared with those in the control group,the H reflex scores in the TENS group were obviously decreased,while H reflex latency was prolonged and H/M was reduced. Gait in the TENS group was evidently improved.Conclusion TENS is an effective therapy to decrease gastrocnemi- us spasticity and to improve the gait of stroke patients.

OBJECTIVE To investigate the therapeutic effect and side effect of ibrutinib long-term treatment in systemic lupus erythematosus (SLE) model mice induced by pristane. METHODS Female 6-week old BALB/c mice were ip given pristane 0.5 mL once for SLE induction. Four weeks later, the SLE model mice were divided into three groups based on the body mass and serum level of anti-double-strand DNA (DS-DNA) antibody and treated with 1%methylcellulose (model control group, ig), ibrutinib (30 mg·kg-1, ig) or prednisone (10 mg·kg-1, ig), respectively, once daily for 28 weeks. Every 4 weeks, body mass of each mouse was measured. Autoantibodies against DS-DNA, single-strand DNA (SS-DAN), and histone were tested by ELISA. The incidence of lupus arthritis and clinical score of inflammation and edema were recorded and graded. Biochemical analysis of urea protein, serum urea nitrogen and creatinine was used to evaluate kidney function. Mice were euthanized post 28 weeks of dosing. Inter-leukin-6 (IL-6), interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) were tested by ELISA. The heart, liver, spleen, lung, and kidney were collected and weighed for organ relative mass calculation. Biochemical analysis of serum glutamic-pyruvic transaminase (GPT), glutamic-oxal(o)acetic transaminase (GOT) and alkaline phosphatase (ALP) was used to evaluate liver function. Hind feet were collected for HE staining and pathological scoring to observe renal injury and inflammation. Immunohistochemical staining was used to study IgG immune complexes deposition in kidneys of lupus. RESULTS Compared with normal control group, autoantibodies (anti-DS-DNA, anti-SS-DNA and anti-histone antibodies), renal function indexes (serum creatinine, urea nitrogen and urine protein), and cytokines (IL-6, IFN-γ and TNF-α) levels in model group were significantly increased (P<0.01). The model group mice had obvious clinical symptoms of arthritis (P<0.01), serious inflammation cell invasion (P<0.01), and the mass of kidneys and spleen increased significantly (P<0.01). Compared with model group, after 28 weeks of treatment, ibrutinib decreased the level of anti-DS-DNA, anti-SS-DNA and anti-histone antibodies (P<0.01), decreased the lupus arthritis score (P<0.01) and the morbidity of arthritis, reduced the level of cyto-kines IL-6, IFN-γand TNF-α(P<0.01), reduced the level of serum creatinine, serum urea nitrogen and urine protein (P<0.01), improved pathological symptoms of hind feet such as inflammation, cartilage destruction, bone resorption and pannus (P<0.01), alleviated renal tissue inflammatory cell invasion and the immune-complex precipitation, and reduced the mass of organs (spleen and kidneys, P<0.01) and the level of liver function (GPT and ALP, P<0.01). CONCLUSION Long-term treatment with ibrutinib has therapeutic effect on the model mice of SLE, and has no obvious side effect.

OBJECTIVETo explore Chinese medical syndrome distribution features of Japanese encephalitis (JE), and to analyze its correlation between syndromes and features of etiologies and pathogeneses.

METHODSRecruited were 277 patients with confirmative diagnosis of JE from Wuhan Medical Treatment Center, Children's Hospital Affiliated to Chongqing Medical University, Fifth People's Hospital of Guiyang City, Hangzhou Sixth People's Hospital, and Chengdu Hospital of Infectious Diseases between July to September 2012. Chinese medical syndrome distribution features were summarized from their general materials and detailed records of clinical data, including medical history, symptoms and signs, tongue fur, and pulse figures.The frequency of symptoms and signs was calculated according to mild, ordinary, severe, extreme severe degrees. The distribution of Chinese medical syndromes was summarized. And its correlation between syndromes and features of etiologies and pathogeneses were analyzed.

RESULTSAfter clustering analysis, Chinese medical syndromes of JE could be categorized as four groups: toxicity accumulation in Fei and Wei syndrome (TAFWS), brain collateral impaired by poison syndrome (BCIPS), depression of toxicity in the pericardium syndrome (DTPS), exhaustion of yin and yang syndrome (EYYS). BCIPS and DTPS were dominated, accounting for 74.0% (205 cases). The main causes covered evil of summer heat [accounting for 92.42% (256/277 cases)], heat [accounting for 87.73% (243/277 cases)], and toxin [accounting for 99.64% (276/277 cases)].

CONCLUSIONSThe four Chinese medical syndrome types of JE met Chinese medical clinical features of encephalitis. It is induced by infestation of dampness-heat, resulting in toxicity accumulation in Fei and Wei, brain collateral impaired by poison, depression of toxicity in the pericardium. Yin fluid and blood is exhausted as time goes by. Qi and yin are impaired to form intermingled deficiency and excess, and finally causing exhaustion of yin and yang.

OBJECTIVETo observe the effect of Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood on the expression of interferon-γ (IFN-γ)/interleukin-4 (IL-4) in peripheral blood and disease activity in primary Sjogren's syndrome (pSS) patients, and to study the relationship between the immune balance of Th1/Th2 and the disease activity.

METHODSA total of 66 pSS patients were randomized with tossing coins method into two groups: the integrative therapy group (34 cases) and the control group (32 cases); and 28 healthy subjects were taken as the normal group. The integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets and the control group was treated with hydroxychloroquine sulfate tablets. The treatment course was 3 months for both groups. The levels of serum immunoglobulin G (IgG), erythrocyte sedimentation rate (ESR), IFN-γ and IL-4 in peripheral blood were measured before and after treatment.

RESULTSCompared with the normal group, the levels of IgG, ESR, IFN-γ and IL-4 were significantly increased in pSS patients (P<0.05). Remarkably, after 3 months of treatment, these levels were dramatically decreased in both the integrative therapy group and the control group, although still higher than the normal group. The levels of IgG, ESR, IFN-γ and IL-4 in the integrative therapy group were lower than the control group and the same group before treatment (P<0.05). The ratio of IFN-γ/IL-4 also significantly decreased after treatment. Moreover, the level of IFN-γ and the ratio of IFN-γ/IL-4 in the integrative therapy group were significantly lower than the control group (P<0.05). For all patients the ratio of IFN-γ/IL-4 before and after treatment was positive correlated with the levels of IgG and ESR.

CONCLUSIONChinese herbal medicine for nourishing yin, supplementing qi, and activating blood can alleviate the disease activity of pSS by regulating the immune balance of Th1/Th2.

OBJECTIVETo explore the effect on the iso-center and OAR and PDD of the MV class X-ray coming from the linac when we use the glass mirror to replace an imported one.

METHODData collected by using a film and 3D water phantom OAR and PDD measuring methods based on the different conditions. Comparison and analysis of the effect levels for different thickness and material mirrors are made.

RESULTThe PDD max error of the 4 mm general glass mirror is 6%.When the 8MV X-ray 720 Gy irradiation is given, the light field appears a dual cross lines and has darker brightness. The PDD max error of the 1.5 mm quartz glass mirror is less than 1%. When it accepts the equal radiation dose, the light field iso-center and OAR and field brightness are agreed well with clinical demands.

CONCLUSIONOur practice shows that the 4 mm general glass mirror can't suffer the MV class X-ray irradiation but the thin quartz glass mirror can. So the thin quartz glass mirror can be used for the linac.

OBJECTIVE: Using computer simulation to analyze the effects of speed, type of automobile and impacted position on crash-course and injuries of pedestrians in automobile vs. pedestrian accidents. METHODS: Automobiles (bus, minibus, car and truck) and pedestrian models were constructed with multi-body dynamics computing method. The crashes were simulated at different impact speeds (20, 30, 40, 50 and 60 km/h) and different positions (front, lateral and rear of pedestrians). Crash-courses and their biomechanical responses were studied. RESULTS: If the type of automobile and impact position were the same, the crash-courses were similar (impact speed < or = 60 km/h). There were some characteristics in the head acceleration, upper neck axial force and leg axial force. CONCLUSION Multi-body dynamics computer simulation of crash can be applied to analyze crash-course and injuries (head, neck and leg) of pedestrians.

OBJECTIVETo observe the effect of needling at Baihui(DU20), Shuigou(DU26) and Shenmen(HT7) on glucose metabolism in different regions of the brain in vascular dementia patients.

METHODSTen patients with vascular dementia were randomized into 2 groups, and the patients in the control group received the treatment with needling in the routine acupoints for hemiplegia (chosen from 6 Yang meridians of the hand and foot), while those in treatment group received needling at 3 additional acupoints, namely Baihui(DU20), Shuigou(DU26) and Shenmen(HT7), which were specific for dementia treatment. All the patients were examined by positron-emission tomography(PET) to detect the glucose metabolism in different brain regions before and after acupuncture treatment by means of semiquantitative analysis of the average values of radioactive count in the brain regions.

RESULTSNeedling at the additional 3 acupoints could obviously enhance glucose metabolism in the bilateral frontal lobes, bilateral thalamus, temporal lobe and lentiform nucleus on the uncompromised side.

CONCLUSIONThe effect of needling at Baihui(DU20), Shuigou(DU26) and Shenmen(HT7) on vascular dementia is closely related to improved cerebral glucose metabolism.

OBJECTIVETo evaluate the impacts of three different surgical approaches to urethral stricture on the erectile function of the patients.

METHODSThis study included 126 male patients with urethral stricture, 35 treated by substitution urethroplasty (group A), 52 by anastomotic urethroplasty (group B), and 39 by internal urethroplasty (group C). We evaluated the pre- and postoperative erectile function of the patients using IIEF-5 scores by telephone calls and interviews. We also monitored their nocturnal penile tumescence (NPT).

RESULTSThe IIEF-5 scores in groups A, B and C were 13.5 +/- 4.5, 11.1 +/- 4.8 and 14.5 +/- 4.41 respectively after surgery, all significantly decreased as compared with 17.1 +/- 2.6, 17.1 +/- 3.0 and 17.6 +/- 2.2 preoperatively (P < 0.05).

CONCLUSIONAll the three surgical approaches can reduce IIEF-5 scores in patients with urethral stricture, but anastomotic urethroplasty may induce a higher incidence of erectile dysfunction than the other two approaches.
