Cancer Research and Clinic 2013;(4):287-288
Tumor markers for early diagnosis of cancer is an important auxiliary mean,which for early tumor detection,monitoring and for judging curative effect of treatment regimens play important role.Clinical method for early diagnosis on ovarian cancer is the detection of serum CA125,however,its precision and specificity for early diagnosis are not enough.It has been found that in the development period of the patients with ovarian cancer,SMRP and CA125 is co-expression.This article reviews the value of serum mesothelin on diagnosis of epithelial ovarian cancer to provide reference on early diagnosis and treatment.
2.Future perspectives and challenges in the development of an antitumor vaccine based on heat shock protein gp96-peptide complex
Chinese Journal of Clinical Oncology 2014;45(11):738-740
Tumor-derived heat shock protein-peptide complex 96 (HSPPC-96) containing tumor antigenic peptides can elicit po-tent tumor-specific and protective immunity. Autologous HSPPC-96 vaccine has been shown to effectively prolong recurrence-free sur-vival and increase the overall survival of many tumors, thereby suggesting extensive future applications. However, as an autologous tu-mor-derived individual vaccine, the development of HSPPC-96 vaccine is challenged by the lack of an adequate autologous tumor, lim-ited efficacy for advanced-stage cancer, etc. This paper summarized the progress, future perspectives, and challenges in the clinical de-velopment of HSPPC-96 vaccine immunotherapy.

6.Asymmetric dimethylarginine and atherosclerosis
Chinese Journal of Pathophysiology 1989;0(05):-
Asymmetric dimethylarginine(ADMA)is an endogenous inhibitor of nitric oxide synthase(NOS).it reduces nitric oxide production. ADMA is correlated with the risk factors of atherosclerosis, such as hypercholesterolemia, hypertension and hyperglycaemia. Accumulating evidence suggests that a derangement of the NOS pathway plays a critical role in atherogenesis and ADMA may participate in the process.

International Eye Science 2014;(6):1064-1067
AIM: To contrast the effect of small incision phacoemulsification and non-phacoemulsification to treat cataract.
METHODS: Totally 172 patients with cataract were divided into 2 groups ( n = 86 ) randomly. Patients in Group Phaco were treated with phacoemulsification and, while those in Group Siecs were treated with small incision extracapsular cataract surgery and intraocular lens implantation. They were all followed up for 1-3y. Functional examinations were made at 3d;1,6mo and last follow - up. The visual acuity, intraocular pressure, anterior chamber depth, average corneal power ( ACP ) , cylinder ( CYL ) , surface asymmetry index ( SAI ) and complications were contrasted between groups.
RESULTS: At 3d after operation, the visual acuity of Group Phaco was better than that of Group Siecs ( P<0-05), and CYL, SAI and intraocular pressure of Group Phaco were all significantly lower than those of Group Siecs (P<0. 05). At 1mo after operation, the visual acuity of Group Phaco was better than that of Group Siecs ( P<0-05), and CYL, SAI and intraocular pressure of Group Phaco were slightly lower than those of Group Siecs ( P<0. 05);there was no difference between the two group. At 6mo after operation, the visual acuity of Group Phaco was still better than that of Group Siecs (P<0. 05), and CYL, SAI and intraocular pressure of Group Phaco were flat as those of Group Siecs (P<0. 05); there was no difference between groups in those indexes above ( P > 0. 05 ). Furthermore, the APC and anterior chamber depth of each point- in - time had no significant difference between groups (P>0. 05). The incidences of complication were similar in two groups ( P> 0. 05 ); but with individual differences, patients of GradeII and Ⅲ in Group Phaco got lower complication rate (P<0. 05), while those of Grade Ⅳ higher (P<0. 05) than those of Group Siecs.
CONCLUSION: Our research shows that phacoemulsification has high effect in the treatment of patients with GradeII and Ⅲ nuclear hardness, while small incision extracapsular cataract surgery has high effect in the treatment of patients with Grade Ⅳ nuclear hardness.
8.Research and prospect of tissue engineered blood vessels
Chinese Journal of Tissue Engineering Research 2007;0(33):-
The tissue engineering technology that developed in the 1980s brings a hope for the regeneration of human organs. It is feasible to construct by-pass vessels, which have no immune resistance but are capable of anticoagulation. At present, a huge number of researches have provided the necessary basis for the construction. However, there are still some difficulties on the points of induction and proliferation of endothelial cells, development of new materials for scaffold and co-culture of seed cells in scaffold. These difficulties have become the bottle neck of tissue engineered blood vessels. The tissue engineering vessels are nowadays absent in clinical practice. With the progress in researches of tissue engineering, it is strongly believed that human organs and tissues can be constructed using tissue engineering technology, thus satisfying the donors of organ transplantation.

Chinese Critical Care Medicine 2015;27(11):899-905
Objective To evaluate the effect of the early goal-directed therapy (EGDT) on mortality in patients with septic shock, and to analyze the risk factors of mortality.Methods A retrospective controlled study was conducted.Complete clinical data of patients with septic shock admitted to emergency intensive care unit (EICU) of Sichuan Provincial People's Hospital from May 1994 to December 2014 were recorded and analyzed.According to the International Guidelines for Management of Severe Sepsis and Septic Shock (SSC) with the time of promulgation as dividing point, the patients were divided into two groups as before and after the publication of the guideline, i.e.early group (from May 1994 to April 2004) and late group (from May 2004 to December 2014).The patients of the late group were subdivided into 6-hour and 24-hour reaching standard groups and non-reaching standard group according to the time of reaching standard of EGDT.All patients were divided into death group and survival group according to the 28-day survival.The patients in early group were not treated according to EGDT guidance, so only age, the case history of chronic disease, the main site of infection, organ dysfunction, vital signs, urine output, the amount of fluid for resuscitation, blood routine, blood gas analysis, time for starting antibiotics treatment, the use of vasoactive drugs and hormone, etc.were recorded.The central venous pressure (CVP), central venous oxygen saturation (ScvO2), blood lactate (Lac), and the monitor of other parameters of patients in late group were consummated late.The relationship of EGDT compliance standard time and tissue perfusion index recovery time between the two groups of patients was observed.The risk factor for mortality was analyzed by multiple factors logistic regression.Results ① 134 patients were included,and the overall 28-day mortality was 49.25%.② The 6-hour EGDT compliance rate of early group was 0 (0/58),and it was 28.95% (22/76) in late group (x2 =20.087, P =0.000).Compared with the early group, the 6-hour urine volume in the late group was significantly increased (mL·h-1·kg-1: 1.72± 1.04 vs.0.89±0.24, t =11.950, P =0.001),6-hour mean arterial pressure (MAP, mmHg, 1 mmHg =0.133 kPa) was elevated (64.24±3.90 vs.56.21 ±5.95, t =6.444, P =0.012), the use of antibiotics within 1 hour was increased (76.32% vs.48.28%, x2 =11.250, P =0.001), the use of vasocative drugs (21.05% vs.89.66%, x 2 =61.942, P =0.000) and hormone (8.57% vs.34.48%, x 2 =14.871,P =0.000) were lowered, and the 28-day mortality rate was lowered significantly [34.21% (26/76) vs.68.96% (40/58),x2 =15.897, P =0.000].The difference was not statistically significant in the total recovery of liquid volume between late group and early group (mL: 1 856.31±805.81 vs.1 903.1 ± 897.11, t =0.101, P =0.752).③ In all patients, it was shown by single factor analysis that the age, infection sites, altered mental status at admission, white blood cell (WBC) before treatment, 6-hour urine output after treatment, the number of organ with failure, the use of antibiotics within 1 hour, and incidence of acute renal injury (AKI) or acute lung injury/acute respiratory distress syndrome (ALI/ARDS) within 24 hours were risk factors of 28-day death (P < 0.05 or P < 0.01).In the late group, it was shown by single factor analysis that the age, the case history of chronic disease, infection sites, WBC, pH value, Lac, and ScvO2 before treatment, 6-hour urine output after treatment, the number of organ with failure, the use of antibiotics within 1 hour,and incidence of AKI or ALI/ARDS within 24 hours were risk factors of 28-day death (P < 0.05 or P < 0.01).It was shown by the logistic regression analysis that aging [odds ratio (OR) =4.81, P =0.02], failure of 2 organs (OR =28.63,P =0.00) or ≥ 3 organs (OR =62.69, P =0.00) were the independent risk factors for mortality in patients with septic shock.④ The 76 patients of late group were subdivided into three groups, namely 6-hour reaching standard of EGDT group (n =22), 24-hour reaching standard of EGDT group (n =28), and non-reaching standard of EGDT group (n =28).Compared with those before treatment, the Lac after therapy was decreased obviously both in 6-hour EGDT group and 24-hour EGDT group, and the CVP, MAP, and ScvO2 were increased significantly.The Lac in 6-hour EGDT group was lowered more significantly as compared with that in 24-hour EGDT group (mmol/L: 1.64 ± 0.40 vs.3.01 ± 1.13, P < 0.01),while MAP and ScvO2 were increased significantly [MAP (mmHg): 81.82 ± 8.01 vs.69.01 ± 9.63;ScvO2:0.718 ± 0.034 vs.0.658 ±0.036, P < 0.05 and P < 0.01].The urine output in both reaching standard of EGDT groups was more than 0.5 mL·h-1·kg-1, without statistically different significance.The 28-day mortality rate of 24-hour EGDT group was 14.29%, and it was 0 in 6-hour EGDT group.Conclusions Mortality was as high as 68.96% during 10 years when the period before the use of 2004 SSC, and the mortality rate was lowered to 34.21% during 10 years during which the early fluid resuscitation treatment was based on EGDT.Aging and failure of more than 2 organs were independent risk factors for mortality in patients with septic shock.Compared with reaching the standard of EGDT within 24 hours,reaching the standard of EGDT within 6 hours can rapidly reverse hypoxic-ischemic tissue, thereby improving the prognosis of the patient with lowering of mortality rate.
