Objective To observe the clinical efficacy of cerebral palsy children with liver strong spleen weak syndrome treated with integrated traditional Chinese medicine therapy. Methods Eighty cerebral palsy children with liver strong spleen weak syndrome were divided into treatment group (40 cases) and control group (40 cases). Patients in control group were treated with conventional therapy (including exercise therapy, occupational therapy, guidance education, physical factors, and psychological therapy), and patients in treatment group were treated with integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) additionally. Three months were set for a course of treatment, and the whole treatment lasted for a total of four courses. TCM clinical symptoms were scored every six months, muscle tone (MAS), gross motor function (GMFM), and daily life activity ability (MBI) were evaluated every three months for both groups. Results There were significant differences in the total scores of TCM clinical symptom, MAS, GMFM, and MBI at different treatment time points in the two groups, compared with that before treatment (P<0.01). There were significant differences in the total scores of clinical symptom for Chinese medicine, MAS, GMFM, and MBI at different treatment time points for treatment group, compared with that of control group (P<0.05). Conclusion Integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) for cerebral palsy children on the basis of western medicine therapy can more effectively improve function and life quality of children patients.

Objective To investigate the effects of fasudil hydrochloride on learning and memory, and the autophagy in hippocampal CA1 neurons in subarachnoid hemorrhage (SAH) rats. Methods Fifty-four male Sprague-Dawley rats were randomly divided into sham group (n=18), SAH group (n=18) and drug group (n=18). Subarachnoid hemorrhage model was established with internal carotid artery punc-ture. The drug group was injected fasudil hydrochloride 10 mg/kg intraperitoneally after modeling per 24 hours, while the sham group and SAH group were injected the same volume of saline. They were tested with shuttle box test 6, 24 and 72 hours after intervention, then the hippocampal CA1 area was stained with HE and immunohistochemistry to observe the morphology of cells and the expression of Beclin-1 and microtubule-associated protein 1 light chain 3 II (LC3-II). Results Compared with the sham group, the frequence of avoidance de-creased in SAH group at each time point (P<0.05), while the avoidance reaction time increased (P<0.05);the survival of neurons in hippo-campal CA1 area decreased (P<0.05), and the expression of Beclin-1 and LC3-II increased (P<0.05). Compared with SAH group, the fre-quence of avoidance increased in the drug group at each time point (P<0.05), while the avoidance reaction time decreased (P<0.05);the sur-vival of neurons in hippocampal CA1 area increased (P<0.05) and the expression of Beclin-1 and LC3-II increased further (P<0.05). Con-clusion Fasudil hydrochloride can improve learning and memory ability and protect neurons from damage, which may associate with the ex-cess of autophagy activation in hippocampal CA1 areas in SAH rats.

Objective: To investigate the mechanism of miR-503 modulates radio-resistance of esophageal squamous cell carcinoma (ESCC) by targeting excision-repair cross-complementing 1 (ERCC1). Methods: The expression level of miR-503 in radio-resistant ESCC tumor tissues and KYSE140 and KYSE140R cells was detected by qPCR. The miR-503 mimic, miR-503 inhibitor or si-ERCC1 was transfected into KYSE140 and KYSE140R cells.After radiation treatment, the colony formation assay and CCK-8 assay were used to detect the proliferation of KYSE140R cells. Flow cytometry was used to detect apoptosis of KYSE140R cells. WB was used to detect changes in protein expression of ERCC1. Dual luciferase reporter gene assay was used to validate the targeting relationship between miR-503 and ERCC1. Results: The expression level of miR-503 was down-regulated in radio-resistant tissues and ESCC cell lines (all P<0.01). Over-expression of miR-503 significantly inhibited cell proliferation and promoted apoptosis of KYSE140R cells (all P<0.01). Dual-luciferase reporter assay validated that ERCC1 was a target gene of miR-503, and miR-503 negatively regulated the expression of ERCC1. Over-expression of miR-503 significantly down-regulated the expression of ERCC1 in KYSE140 and KYSE140R cells (both P<0.01), inhibited cell proliferation (both P<0.01), but significantly increased apoptosis rate (all P<0.01); knockdown of ERCC1 exhibited a similar effect, while knockdown of both ERCC1 and miR-503 reversed the above effects. Conclusion: Over-expression of miR-503 up-regulated the radio-sensitivity of KYSE140R cells by targeting ERCC1.

ABSTRACT:Objective To explore role of U0126,the specific inhibitor of ERK signaling pathway,in early brain injury (EBI)and the autophagy of nerve cells in hippocampus area in subarachnoid hemorrhage (SAH). Methods A total of 48 male adult SD rats were randomly divided into control group,SAH group,DMSO+SAH group,and U0126+SAH group,with 12 in each.We established SAH rat model by the puncture of internal carotid artery.The same amount of saline water,DMSO and U0126 solution of 0.5 mL per rat was injected respectively into the rats of different groups 30 min before modeling.The rats were killed at 24 h.To measure brain water content by Wet and dry method after 24 h,the morphological changes of hippocampus CA1 neural cells were observed by microscopy;the expression levels of ERK,Beclin-1 and LC3 were detected by using immunohistochemical method. Results Compared with that in sham group,brain water content increased obviously in SAH model group.The density of surviving neurons in SAH group was significantly lower than that in control group (P<0 .0 5 ).ERK signaling pathway was activated obviously,the expressions of Beclin 1 and LC3-Ⅱ were significantly higher than those in control group (P<0.05).Compared with SAH model group,in U0126 group brain water content increased obviously.Compared with those in SAH group,the density of surviving neurons was significantly lower (P<0.05), ERK signaling pathway was suppressed,the expressions of Beclin-1 and LC3-Ⅱ were significantly lower (P<0.05). Conclusion The U0126,the ERK signaling pathway inhibitor,can inhibit neuron autophagy and increase EBR of SAH.

Objective To determine the relationship between expression of topoisomerase Ⅱ α and clinicopathological factors,overall survival in colorectal caner.Methods Expression of topoisomerase Ⅱ α was measured using EnVision immunohistochemistry in 490 colorectal cancer patients.The relationship between topoisomerase Ⅱ α expression and various clinicopathological parameters was analyzed.Kaplan-Meier analyses and multivariate analyses were used to evaluate the significance of topoisomerase Ⅱ α expression in prognosis prediction.Results Overexpression of topoisomerase Ⅱ α was found to be related with lower T stage ( P =0.042 ),lower N stage ( P =0.038 ),and possibly with lower recurrence rate ( P =0.053 ).Kaplan- Meier analyses showed that overexpression of topoisomerase Ⅱ α was related with prolonged overall survival (P =0.022 ) and prolonged disease-free survival ( P =0.036).Multivariate analyses showed that elevated serum CEA ( P ＜ 0.001 ),elevated serum CA199 ( P =0.002 ),poor differentiation ( P =0.001 ),advanced Dukes stage ( P ＜ 0.001 ) and lower expression of topoisomerase Ⅱ α( P =0.017 ) were independent predictive factors for poor prognosis.Conclusions Expression of topoisomerase Ⅱ α is a favorable predictive factor for colorectal cancer,and would be useful in prognosis prediction and treatment selection for early colorectal cancer and malignant colorectal polyps,especially when it is used in combinations with serum CEA,CA199 and differentiation.

Objective To evaluate the clinical outcomes of different flaps for repairing the soft tissue defects of heels.Methods A total of 26 patients with soft tissue defects around the heel treated modified propeller perforator flap,medialis pedis flap,or anterolateral thigh flap from March 2012 to June 2016 were analyzed retrospectively.There included 19 males and 7 females,aged 4-64 years (mean,38.1 years).There were 9 patients with posterior heel defect,3 with weight-bearing defect,6 with posterior medial defect and 8 with posterolateral defect.The wound areas were from 6.0 cm × 4.0 cm to 12.0 cm × 9.5 cm,while the flap areas were from 7.0 cm × 5.0 cm to 13.5 cm × 10.5 cm.According to the principle of flap selection,the pedicled skin flap instead of free skin flap was selected in order to minimize damage to the donor site area.Modified propeller perforator flap was applied in 13 patients,medialis pedis flap in 3 patients and anterolateral thigh flap in 14 patients.The flap donor site was directly sutured in 23 patients and a simultaneous skin graft was applied in 3 patients.The survival rate,appearance,texture and feeling recovery of flaps,complications,walking ability,and the status of donor sites were compared.Besides,postoperative functions of all cases were estimated according to foot scoring scale of American Orthopaedic Foot and Ankle Society (AOFAS).Results All flaps survived well in 26 patients.The wounds of flaps and flap donor sites were healed at Ⅰ stage.A total of 24 patients were followed up for 12-36 months (average 16 months).The appearance,color and texture of the flaps were good.There was no ulcer in flaps or flap donor sites.The protective feeling of flaps was recovered and the feeling of distinguishing two points was 6-13 mm.Modified propeller perforator flap donor site was directly sutured,the wound of which showed a linear healing.There was no fat deformity or obvious scar formation around ankle.The skin graft of the medialis pedis flap donor site was healed well,without scar hyperplasia,rupture,or deformity of arch.The anterolateral thigh flap was healed linearly without scar,and the anterolateral skin felt slightly depressed.The muscle strength of the four biceps femoris muscle was 4.According to AOFAS score,the feet's functions were evaluated as excellent in 5,good in 16,fair in 4,and poor in 1,with excellence rate of 81％.Conclusions For different soft tissue defects of the heels,propeller perforators flap,medial plantar flap or anterolateral thigh flap can not only attain appearance reconstruction of the defects and good functional recovery,but also minimize the injury of flap donor site.

Objective To observe the effect of spleen-warming and kidney-tonifying therapy on Toll-like receptor 4 (TLR4) signaling pathway of cerebral infarction sequelae patients. Methods A total of 60 cerebral infarction sequelae patients with spleen and kidney(yang) deficiency were divided into control group and treatment group, 30 cases in each group. The two groups were given function rehabilitation training following by the theory of modern rehabilitation medicine, and additionally the treatment group was treated with spleen-warming and kidney-tonifying herbs orally. The treatment period for the two groups averaged 3 months. Before and after treatment, the scores of traditional Chinese medicine (TCM) symptoms and signs, peripheral blood TLR4 mRNA expression level, and the inflammation-related factors in the two groups were observed, and the observation parameters were compared with 30 healthy volunteers. Meanwhile, the changes of modern rehabilitation evaluation indexes were also evaluated before and after treatment. Results (1) After treatment, the Fugl-Meyer scores for motor function and Modified Barthel Index(MBI) scores for activities of daily living in the treatment group were obviously increased(P < 0.05 or P < 0.01 compared with those before treatment); the MBI scores in the control group was much increased(P < 0.05 compared with those before treatment), but the Fugl -Meyer scores only showed an increasing trend(P > 0.05). (2) After treatment, the predominant symptoms and signs of hemiplegia, facial distortion and dysphasia in the two groups were much improved(P < 0.01 compared with those before treatment), and the improvement in the treatment group was superior to that in the control group(P < 0.05). The control group had no significant effect on relieving the symptoms and signs of dizziness and blurred vision, numbness of limbs, spontaneous sweating, shortness of breath and weakness, and darkish tongue(P > 0.05 compared with those before treatment); the treatment group had obvious effect on the above symptoms and signs, and the effect was superior to that in the control group(P < 0.05 or P < 0.01).(3) For the inflammation-related factors, tumor necrosis factor alpha(TNF-α) level in the treatment group was much decreased and even arrived to the normal level(P > 0.05), and TNF-α level in the control group was decreased but did not arrive to the normal level(P < 0.05); levels of interleukin(IL)-1β, IL-6 and TLR4 mRNA in the two groups were decreased but did not arrive to the normal(P < 0.01), and the decrease in the treatment group was superior to that in the control group(P < 0.05 or P < 0.01). (4) During the treatment period, no obvious adverse effect was found in the two groups. Conclusion Oral use of spleen -warming and kidney –tonifying Chinese medicine combined with modern rehabilitation therapy is effective for the treatment of the sequelae of cerebral infarction patients by relieving the clinical TCM symptoms, and one of the therapeutic mechanisms is probably related with the TLR4 signaling pathway through regulating the expression of inflammatory factors.
