Objective To observe the effects of intensive lower extremity motor control training on the motor function of lower extremity, balance and walking capability of stroke patients. Methods 40 stroke patients were randomized into the intervention group (n=20) and control group (n=20). Both groups received the routine rehabilitation, while the intervention group accepted the lower extremity motor control training in addition for 6 weeks. Before and after 6 weeks of treatments, they were assessed with Fugl-Meyer Assessment of lower extremity (FMA-L), Berg Balance Scale (BBS), Holden Functional Ambulation Category (FAC); their gaits were analysesd with footprint. Results Both groups improved significantly in scores of FMA-L, BBS, FAC and average step length, stride width, walking velocity (P<0.01) after treatment, and improved more in the intervention group than in the control group (P<0.05). Conclusion Intensive motor control training of lower extremity may promote the recovery of motor function of lower extremities, balance and walking ability of stroke patients.

To explore the antagonistic effect of gingerols against the inflammation induced by lectin from Pinellia ternata. In this study, ELISA method was used to determine the effect of different extracts from gingerols on the release of inflammatory factor TNF-α from macrophages induced by lectin from P. ternata. The fluorescence probe was used to determine the effect of gingerols on the changes in ROS of macrophages induced by lectin from P. ternata. The western-blot method was applied to study the effect of gingerols on the increase in expression of cell receptor interacting protein RIP3 in macrophages induced by lectin from P. ternata. The scanning electron microscope (SEM) was used to study the effect of gingerols on morphological changes in macrophages induced by lectin from P. ternata. According to the results, gingerols can significantly inhibit the release of inflammatory factor from macrophages induced by lectin from P. ternata, ROS overproduction and increase in RIP3 expression. SEM results showed that gingerols can inhibit the cytomorphosis and necrocytosis induced by lectin from P. ternata. Fresh ginger's detoxication may be related to gingerols' effects in inhibiing release of inflammatory factor, ROS overproduction and increase in RIP3 expression caused by macrophages induced by lectin from P. ternata, which are mainly inflammatory development.

OBJECTIVETo evaluate the safety and effectiveness of GreenLight 120-W laser photoselective vaporization of the prostate (PVP) versus transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).
METHODSWe searched PubMed, Medline, Embase, Cochrane Library, Wanfang, CNKI, and VIP for randomized control trials and their references addressing 120-W PVP versus TURP in the treatment of BPH. Based on the inclusion and exclusion criteria, two reviewers independently accomplished the screening, quality assessment, and data extraction of the identified studies and performed meta-analyses using RevMan 5.2.
RESULTSTotally, 6 randomized control trials were included in this analysis, involving 703 cases, 351 treated by PVP and 352 by TURP. Compared with TURP, PVP showed significantly decreased time of catheterization (by 32. 55 hours, 95% CI 15.3 -49.8, P < 0.01), hospital stay (by 1.85 days, 95% CI 1.2-2.5, P < 0.01), and intraoperative blood loss (by 15.6 g/L, 95% CI 10.0-21.2, P < 0.01), but increased time of operation (by 9.37 minutes, 95% CI 5. 1-13.6, P < 0.01). There was also a significant reduction in blood transfusion, TUR syndrome, and capsular perforation in the PVP group. At 12 months after surgery, no statistically significant differences were found between the two groups in the improvement of maximum urinary flow rate, IPSS, postvoid residual, and sexual function.
CONCLUSIONGreenLight 120-W laser PVP is a safe and effective procedure for the treatment of BPH, with similar effectiveness to TURP but less blood loss, shorter time of catheterization and hospital stay, and lower incidences of blood transfusion, TUR syndrome and capsular perforation.

OBJECTIVETo investigate the changes of protein kinase C (PKC) activity and its role in the development of presyrinx state in rabbits.
METHODSPresyrinx state was established in 56 rabbits by intra-cisternal injection of kaolin. At 1, 3, 7, 14, and 21 days after the injection, the water content in the upper cervical spinal cord was measured, its pathological changes observed microscopically and the PKC activity determined with substrate phosphorolysis kinase assay.
RESULTSSpinal cord edema occurred in rabbits one day after kaolin injection, with water content of (68.35-/+0.70)%, which increased to (72.70-/+0.88)% on day 3, reaching the peak level of (72.92-/+0.86)% on day 7, followed by gradual decline after 3 weeks [(70.03-/+0.77)%]. The membrane PKC activity increased from 5.67-/+0.26 pmol.mg(-1).min(-1) on day 1 after the injection to reach the peak level on day 7 (13.27-/+3.15 pmol.mg(-1).min(-1)), which was maintained till day 14 with subsequent decrease to 8.85-/+1.56 pmol.mg(-1).min(-1) on day 21. The cytoplasmic PKC activity showed changes of a reverse pattern.
CONCLUSIONIn rabbits with experimental presyrinx state, PKC translocation and activation is involved in ischemic spinal edema.

AIMTo investigate the expression of hypoxia-inducible factor-1 alpha (HIF-1alpha) in rats with chronic pulmonary hypertension induced by hypoxia and hypercapnia and its relationship with nitric oxide(NO).
METHODSFourty male Sprague-Dawley rats were randomly divided into four groups, normal control group (NC), hypoxia-hypercapnia group (HH), hypoxia - hypercapnia + L-arginine liposome group(HP) and hypoxia-hypercapnia+ N-nitro-L-arginine methylester group (HM). Colorimetric analysis, immunohistochemistry and in situ hybridization were used for detection of NO, HIF-1alpha and constitutive nitric oxide synthase (ecNOS).
RESULTS(1) The mean pulmonary arterial pressure (mPAP) and the weight ratio of right ventricular to left ventricle plus septum (RV/(LV + S)) of HH group were higher than those of NC group (P < 0.05), HP group much lower than HH group (P < 0.01), mPAP of HM higher than HH group ( P < 0.05). 2)0 Contents of NO in plasma and pulmonary tissue homogenates of HH group were much lower than those of NC group (P < 0.01), HP group higher than HH group (P < 0.01). There were no difference between HM group and HH group. (Expression of HIF-1alpha and HIF-1alpha mRNA in pulmonary arterioles of HH group were significantly higher than those of NC group( P < 0.01), HP group lower than HH group (P < 0.01) ,HM group higher than HH group (P < 0.01); Whereas expression of ecNOS and ecNOS mRNA in pulmonary arterioles of HH were lower than those of NC group( P < 0.05, IP group higher than HH group (P < 0.01), HM group lower than HH group (P < 0.05).
CONCLUSIONHIF-1alpha is involved in the pathogenesis of chronic pulmonary hypertension induced by hypoxia and hypercapnia. The protective function of NO in the pathogenesis might be partly depended on its effects on the expression/activity of HIF-1alpha in lung.

BACKGROUNDTo investigate the correlation of clinical features with pathology in chronic viral hepatitis (CH).
METHODSAnalyses of single factor and multiple factors of serum biochemical indices, imaging examination results, symptoms and signs with degree of pathological lesion of hepatic tissue in 973 cases of CH were conducted. Meanwhile, the hepatic functional index (AAPEA index) was used to investigate the role of serum biochemical indices in diagnosis of CH.
RESULTSIn these patients with CH,the severity of hepatic lesion was closely correlated to symptoms and signs, biochemical indices such as PTA, ALT, TBIL, ALB, A/G, gamma-globulin (gamma-G) by electrophoresis, AST and cholinesterase (CHE) as well as splenic thickness. AST was superior to ALT in reflecting degree of hepatic inflammatory activity. The total mistaken judgment rate of multiple factor analysis was 28.1%. The correlation coefficient of AAPEA index to degrees of hepatic inflammatory activity, fibrosis and pathological grading was 0.559, 0.545 and 0.529, respectively (P<0.000 1)
CONCLUSIONSThe biochemical indices such as PTA, ALT, TBIL, ALB, A/G, gammaG, AST, CHE and the determination of splenic thickness by ultrasonography B could reflect hepatic pathological changes to certain extent. AST was superior to ALT in reflecting degree of hepatic inflammatory activity. Incorrect judgment rate was high in determination of moderate and severe CH by multiple factor analysis. Conformity rate between AAPEA index and pathological diagnosis was better than any of them alone in diagnosing CH.

Objective:To explore the feasibility of technological modification and innovation of full-left/full-right liver splitting in situ for donors and examine the safety of clinical application for liver transplantation (LT).Methods:From March 2021 to June 2022, clinical and surgical data are retrospectively reviewed for 27 donors undergoing full-left/full-right liver splitting in situ and the corresponding 49 recipients undergoing full-left/full-right LT.According to the split liver technique used in donor liver surgery, they are divided into conventional split group(group A, 13 cases)and innovative split group(group B, 14 cases). The corresponding recipients are divided into two groups of recipient C(25 cases)and recipient D(24 cases). General profiles, intraoperative findings, type of vascular allocation and short-term outcomes in two groups are compared.After full-size split liver transplantation(fSLT), follow-ups continued until the end of September 2022.Results:There are 23 males and 4 females in donors.The causes of mortality for donors are traumatic head injury(12 cases)cerebrovascular accident(13 cases)and anoxia encephalopathy(2 cases). Baseline characteristics of two groups indicate that body weight and body mass index(BMI)are higher in group B and blood sodium level is lower than that in group A( P<0.05). No statistical differences exist for the others.Liver splitting time is significantly shorter in group B than that in group A(175 vs.230 min, P=0.022). No significant inter-group difference exists in type of vascular allocation.Retrohepatic inferior vena cava(IVC)is split in one case in group A and 10 cases in group B( P=0.001). Among 20 cases of right hemiliver requiring a reconstruction of segment Ⅴ/Ⅷ venous outflow, 12 cases in group A and 3 cases in group B are reconstructed with conventional independent bridging method(independent type)while another 5 cases in group B reconstruct with innovated technique by bridging Ⅴ/Ⅷ vein for splitting IVC with iliac vessel and molding all outflows as one for anastomosis(combined typ e). There is significant inter-group difference( P=0.004). No significant differences exist in operative duration, anhepatic phase or blood loss between groups C and B, except for T tube retaining in 7 cases of group A and 14 cases of group D( P=0.032). Twelve cases developed a total of 26 instances of≥Clavien-Dindo grade Ⅲ complications.Of which, 7 cases in group C and 5 cases in group D show no significant difference in postoperative morbidity.However, for serious biliary complications(≥Clavien Dindo grade Ⅲ), there are 6 cases in group C versus none in group D( P=0.016). Two cases died from postoperative complication with a postoperative mortality rate of 4.1%.Postoperative hospital stay is similar in two groups.And accumulates 6/12-month survivals were 95.9% and 87.7% for grafts and 95.9% and 92.4% for recipients respectively. Conclusions:Operative duration of full-left/full-right liver splitting in situ tends to shorten with an accumulation of a certain amount of cases.Technological modification and innovation in IVC splitting and segment Ⅴ/Ⅷ vein reconstruction should be further validated as both feasible and safe by short-term outcomes of the corresponding recipients.

OBJECTIVETo observe early intervention effects of Modified Shuyu Pill (MSP) on vascular cognitive impairment no dementia (VCIND).
METHODSTotally 100 patients VCIND were randomly assigned to the treatment group (43 cases) and the control group (33 cases). On the basis of the treatment targeting risk factors of blood vessels, patients in the treatment group were treated by MSP, while those in the control group were treated by donepezil hydrochloride. The therapeutic course was 16 weeks. The neuropsychological scales [mini-mental state examination (MMSE) and Montreal cognitive assessment (MOCA) score] and Chinese medicine dementia syndromes scales were observed before and after treatment.
RESULTSThe MMSE and MOCA score of the two groups increased when compared with the same group before treatment (P < 0.01). But there was no statistical difference in MMSE or MOCA score after treatment between the two groups (P > 0.05). The Chinese medicine dementia syndromes scales significantly decreased in the treatment group when compared with before treatment (P < 0.01). But there was no statistical difference in Chinese medicine dementia syndromes scales in the control group between before and after treatment (P > 0.05). There was statistical difference in Chinese medicine dementia syndromes scales after treatment between the two groups (P < 0.01).
CONCLUSIONMSP could effectively intervene the progress of VCIND.
