The event of “diagnosing mental disorder but actually not” violates patients′right of informed con-sent and refused to health , showing some problems of “diagnosing mental disorder but actually not” and mandatory admission process and psychiatric judicial authentication , and also have some ethical problems .Therefore, relevant departments should perfect the laws and regulation , establish a hospitalized psychiatric patients appeal , the appeal channels , at the same time , physicians should follow a correct understanding , respect patients rights , disinterest-ed, the ethical principles of self -supervision and also use constraints should be regulated .

OBJECTIVE:To evaluate the effect of temozolomide(TMZ)in combination with dexamethasone(DXM)on the proliferation of human gliocytoma U251 cells in vitro.METHODS:Human U251 cells were assigned to 1 of the 3 groups: TMZ(10,25,50,100,200,400?mol?L~(-1),respectively)alone or in combination with 40?mol?L~(-1)DXM(TMZ+DXM group)or control group(none drug).After treatment for 72 hours,the cell morphology,cell inhibition ratio,cell cycle and the apoptotic rate were detected.RESULTS:When TMZ concentration was greater than 100?mol?L~(-1)the cell inhibition ratio was higher in TMZ-treated group than in TMZ+DXM-treated group(P

BackgroundWith the number of diabetics increases,people pay more attention to the diabetic keratopathy.The major mechanism leading to diabetic keratopathy is diabetic corneal neuropathy.So it is significant to observe pathologic mechanism of diabetic corneal neuropathy. Objective To investigate the protective effects of edaravone( a free radical scavenger) on corneal nerve of rats with experimental diabetic corneal neuropathy,then explain the effects of oxidative stress in the pathologic mechanism of diabetic corneal neuropathy. Methods Seventy Sprague-Daxley male rats were taken as experimental subjects and 20 of them were used as normal control group.The remaining 50 were induced to be diabetic mellitus by a single intraperitoneal injection of streptozotocin and divided into 2 groups randomly:edaravone treated group and diabetic control group.In the edaravone treated group,edaravone(0.2 g/L) eye drops were used 3 times a day until the animal was killed.Five rats in each group were sacrificed at 6,8,10 and 12 weeks respectively.Then the corneal sensation,number of corneal nerve fibers,morphology,content of malondialdehyde(MDA) and activity of superoxide dismutase(SOD) in the corneal tissue were detected.ResultsIn the diabetic control group,the corneal sensation and the number of corneal nerve fibers were decreased,the density of neural network for cluster was sparse,the nerve activity was decreased,the content of MDA in the corneal tissue was significantly increased,the activity of SOD in the corneal tissue was significantly decreased (P＜0.01 ).Accompany with the course of disease,the above change was obvious day after day.Compared with the diabetic control group,the corneal sensation and the morphological abnormalities in corneal nerve of edaravone group were improved significantly which had the partial branches to the 12th week,the content of MDA in the corneal tissue was significantly decreased,the activity of SOD in the corneal tissue was significantly increased (P＜0.01).Conclusions Edaravone can lower diabetic corneal nerve of rats with experimental diabetic corneal neuropathyinjury,Oxidative stress may be a critical pathologic mechanism of diabetic corneal neuropathy.

There are one third of synthesized proteins must be secreted to the cell surface or to the surrounding environment to acquire their native functional state. Most of them are exported by Sec translocase (secretion pathway). Sec translocase consists of a membrane embedded protein-conducting channel, termed SecYEG and a peripherally associated motor domain, the ATPase SecA. The SecDFyajC heterotrimeric membrane protein complex can facilitates protein translocation. SecB is a molecular chaperone that functions in the protein translocation pathway. SecM (secretion monitor) encoded by the 5' region of the secM-secA mRNA, which elongation arrest is required for upregulated expression of SecA. The signal sequence in the N terminus of the nascent peptide is first recognized by the signal recognition particle (SRP). SecB, the Sec-system-specific chaperone, channels the preprotein to the Sec translocation pathway and, ad- ditionally, actively targets the bound precursor to the translocase by its ability to bind SecA. The preprotein-bearing SecA then binds to the membrane, at a high-affinity SecA-binding site, SecYEG, which constitutes a channel for polypeptide movement. Continued translocation requires cycles of ATP hydrolysis bySecA, which is thought to occur in a step-wise fashion with a step of 20~30 amino acid residues.

Objective To investigate the effect of Tegafur, Gimeracil and Oteracil Potassium Capsules ( TS-1 ) on peripheral blood tissue polypeptide antigen (TPS), soluble MHC class I chain-related molecules A (sMICA), hypoxia-inducible factor-1 (HIF-1α) and human epidermal growth factor receptor 2 ( Her-2 ) in the treatment of patients with advanced cervical cancer.Methods 80 cases with advanced cervical cancer were selected and divided into two groups, 40 cases in the control group were treated with routine clinical therapy, 40 cases in the experimental group were treated with TS-1.Tumor markers, TPS,sMICA,HIF-1αand Her-2 were compared before and after the treatment.Results Compared with the control group, the levels of tumor antigen TA-4,carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCCA) in the experimental group were lower (P<0.05); the TPS, HIF-1, sMICA and Her-2 were lower (P<0.05), and the total effective rate in the treatment group was higher (P<0.05).Conclusion TS-1 has a obvious clinical efficacy in the treatment of advanced cervical cancer.It is speculated that the possible mechanism may reduce the serum tumor marker levels via reducing the TPS and SMICA, HIF-1 alpha, HER-2 levels.

Objective To investigate the clinical effect of hyperbaric oxygen combined with Xianling Gubao capsule in delayed union of elderly proximal femoral fractures.Methods 64 elder patients with proximal femoral fracture form May 2013 to December 2015 in our hospital were selected and divided into two groups.32 cases in the control group were treated with routine clinical treatment, and 32 cases in the experimental group were treated on the basis of the control group with Xianling Gubao capsule combined with hyperbaric oxygen.Fracture healing time and clinical efficacy were compared after the treatment.Results The fracture healing time of experimental group was shorter than that in control group ( P<0.05 ) .The pain degree in experimental group was lower than that in control group ( P<0.05 ) .The efficacy in experimental group was higher than that in control group ( Z =-2.144,P<0.05).There was no significant difference in total adverse reactions between experimental group and control group (χ2 =0.474, P>0.05).Conclusion Xianling Gubao capsule combined with hyperbaric oxygen in the treatment of delayed union of proximal femoral fractures in elderly patients has better clinical curative effect and high safety.

High mobility group box l protein (HMGB1) is a highly conserved non-histone DNA binding protein,which is widely distributed in eukaryotic cells.HMGB1 is an important proinflammatory cytokine,involving in various pathological and physiological processes,such as inflammation,neurogenesis and angiogenesis.In the early stage of intracerebral hemorrhage,HMGB1 can induce secondary brain injury,such as inflammatory reaction,neuronal necrosis,and brain edema.However,in the late stage of intracerebral hemorrhage,HMGB1 can promote angiogenesis and neurogenesis,and thus improving neurological function.HMGB1 will become a novel therapeutic target for intracerebral hemorrhage in the future.

Yu Chang,a famous doctor in Qing dynasty,puts a high value on criterion, which is the most impor-tant characteristic in his medical moral thoughts. Based on the traditional medical moral, Yu Chang quoted Buddha into medicine and further expounded the medical moral criterion ( restrain the doctors by laws) referring to Buddhist commandment. This article analyzed the detailed medical moral criterion and requirements of carefulness,per-fection,honestyand pursuing the truththat mentioned in Medical Laws. Furthermore, it pointed out the es-sential features and significance of Yu Chang′s medical moral thoughts.
