OBJECTIVETo evaluate the safety and effectiveness of Shengji Ointment (SO) (by external use) in treating infective ulcer patients with yang syndrome (YS).

METHODSA multicenter, stratified, randomized controlled clinical study was used in this study. A random digit table was formed in the ratio of 3:1,440 infective ulcer patients of YS from 5 centers were recruited, 330 in the treatment group (external use of SO, exchange once every 24 h) and 110 in the control group (external use of Votalin, exchange once every 24 h). The therapeutic course consisted of 21 days. The ulcer area, wound depth, pain degree were observed before treatment at day 3, 7, 14, and 21, and safety indices monitored at the same time.

RESULTSThe ulcer area was significantly reduced in the treatment group after 21-day medication, obviously superior to that of the control group (P = 0.002). Ulcer areas at different time points were analyzed. From the 7th day of medication the reduced area was obviously less in the treatment than in the control group (P = 0.002). Besides, the longer the more obvious difference. Compared with the control group, the healing rate of ulcer area, the pain disappearance rate, and the healing rate of ulcer depth were all obviously improved in the treatment group (all P < 0.01). No adverse event occurred in the two groups.

CONCLUSIONSExternal use of SO was safe and effective in treating infective ulcer patients with YS. It could accelerate wound healing with better analgesic effect.

BACKGROUND:The biological function of human periodontal ligament stem cells is a hot area of research in the treatment of periodontal disease. Human periodontal ligament cells are one of the end cells derived from human periodontal ligament stem cells;meanwhile, it can also provide supports to the development of human periodontal ligament stem cells. However, few studies are reported about the difference of biological characteristics between human periodontal ligament stem cells and human periodontal ligament cells. OBJECTIVE:To compare the differences of biological characteristics between human periodontal ligament stem cells and human periodontal ligament cells. METHODS:The human periodontal ligament stem cells and human periodontal ligament cells were isolated and purified using tissue explant method and cellclone method, respectively, and then were observed under light microscope to compare the differences of morphology. cellproliferation curves of human periodontal ligament stem cells and human periodontal ligament cells were drawn respectively with cellcounting kit 8 assay. Flow cytometry analysis was used to detect their cellcircles and their surface markers expressions. The alkaline phosphatase gene, proliferating cellnuclear antigen gene and Scleraxis gene of human periodontal ligament stem cells and human periodontal ligament cells were detected by Real-time PCR assay.RESULTS AND CONCLUSION:The human periodontal ligament stem cells and human periodontal ligament cells showed a notable difference in morphology under the light microscope observation. During the first 5 days, the cellproliferation curve of human periodontal ligament stem cells was lower than that of human periodontal ligament cells, but 5 days later, the curve of human periodontal ligament stem cells was significantly higher than that of human periodontal ligament cells. The cellcircles of human periodontal ligament stem cells and human periodontal ligament cells were 41.1%and 23.9%, respectively. The surface markers of human periodontal ligament stem cells and human periodontal ligament cells were similar, but their expression rates had significant difference. The expressions of alkaline phosphatase gene, proliferating cellnuclear antigen gene and Scleraxis gene of human periodontal ligament stem cells were significantly higher than those of human periodontal ligament cells. The above results suggest that human periodontal ligament stem cells have much stronger potential ability than human periodontal ligament cells in osteogensis and cellproliferation.

Objective To explore the characteristics of etiology,clinical,electroencephalogram(EEG) and prognosis of infantile spasms(IS) with focal seizures(FS).Methods The significance of age onset,seizure patterns and atteration,etiology,video-EEG(VEEG) and evolution of FS correlating to epileptic spasms(ES),which occurred in 12 cases with IS by means of clinical observation,cranial CT or MRI,VEEG monitory and follow up were investigated.Twelve cases were divided into group A,B,C according to the stages of FS occurring prece-ding,coinciding and following ES.Results Ten cases with IS were identified from focal cortical dysplasia,tuberous scleroses complex,temporal lobe cyst or scleroses and hypoxic-ischemic encephalopathy and others.Clinical manifestation presented FS at certain times during the course of the disease,and other characteristics of frequent attacks,asymmetric spasms or tonic spasms,some atypical seizures in the eyes and the head,motionless staring and focal motor seizures and other.The correlation of ES to FS occurred during one ictal episode as follows:FS→ES(6 cases),ES→FS→ES(1 case),ES→FS(3 cases).FS appeared more frequently,atypical,predominantly involving ocular,facial,oral movement or generalized convulsion,migrating or alternating seizures,associated with epileptic discharges of posterior parietal-occipital and parietal-temporal-occipital origins in group A and early period of group B;whereas in the late period of group B and group C,FS occurred less frequently and more stable,presenting complex partial seizures or secondarily generalized seizures originated mainly from frontal and surrounding areas in the lateralized or bilateral hemispheres.Regarding the natural evolution and development of IS,2 cases with early FS developed into IS;6 cases with IS evolved into Lennox-Gastaut syndrome or symtomatic generalized epilepsy,4 cases got into FS,1 case maintained in a peculiarly epileptic state with FS as well as ES until the operation at 4.5 years old,and the other case was not identified clearly.Conclusions IS coincided with FS is a special kind of aged-related FS associated with secondarily generalized seizures and epileptic encephalopathy.The multiple etiology,seizure patterns,ictal-interictal EEG,clinical evolution and prognosis of the disorder,indicate a complicated interaction of the immature cortico-subcortical abnormalities in the critical developmental period and thereafter,can be identified as a peculiar form of clinical epileptic syndrome.

Objective:To investigate the effect and safety of tacrolimus combined with Okra capsule in treatment of the refractory membranous nephropathy.Methods:Selected 60 patients with refiactory membranous nephropathy who were treated in our hospital from March 2014 to October 2015,and they were divided into observation group and control group with 30 cases in each group according to the random number table method.The control group was treated with prednisone,and the observation group was treated with tacrolimus combined with Okra capsule on the basis of the control group,the courses of treatment were 6 months in two groups.The clinical effects were observed in two groups,the levels of urine protein (uPRO),serum Albumin (sALB),serum Creatinine (sCr),serum Alanine aminotransferase (sALT),tumor necrosis factor-α (TNF-α) and transforming growth factor-β 1 (TGF-β1) were detected and compared in two groups before and after treatment,and the adverse reactions were recorded in two groups.Results:The total effective rate of the ob-servation group was significantly higher than control group (P＜0.05).Compared with before treatment,the levels ofuPRO,TNF-α,TGF-β1 in two groups were decreased after treatment,while sALB,sCr were increased (P＜0.05),and uPRO,TNF-o,TGF-β1 in the observation group were lower than the control group (P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups (P＞0.05).Conclusion:Tacrolimus combined with Huangkui capsule in the treatment ofrefractory membranous nephropathy has good curative effect,reduce renal damage,and low adverse reaction,worthy of promotion.

OBJECTIVE: To investigate the expression of hyperpolarization-activated cyclic nucleotide-gated cation channel 4 (HCN4) and connexin43 (Cx43) in the sinoatrial node of electric shock death. METHODS: As experimental group, 34 cases of electric shock death who had definite current mark evidence were selected from pathology department of Xuzhou Medical College from 2010 to 2013. As the control group, 20 cases of fatal severe craniocerebral injury in traffic accidents were chosen. The expressions of HCN4 and Cx43 in the sinoatrial node were observed by immunohistochemical technology. RESULTS: HCN4 positive cells expressed in the cell membrane and cytoplasm of the sinoatrial node. Cx43 positive cells expressed in the cell membrane and cytoplasm of T cells and myocardial cells. The expression of HCN4 was significantly higher than that of the control group (P < 0.05) and the expression of Cx43 was significantly lower than that of the control group (P < 0.05). CONCLUSION The changes of HCN4 and Cx43 expressions in the sinoatrial node illustrate electric shock death might be related to the abnormalities of cardiac electrophysiology and conduction.
