Proteomics was be widely used in different kinds of diseases recently.The role of proteomics has also expanded from comparative proteomic research to the analysis of function of proteins and interaction of proteins.Our article summarized specially that the role of proteomics may play in the discovery of hepatocellular carcinoma biomarker in the recent years.

Objective To investigate clinical significance of proinsulin and true insulin in obese children with impaired glucose tolerance (IGT).Methods There were 21 IGT and 52 normal glucose tolerance (NGT) children. Control cases were 40 normal children. The levels of serum fasting proinsulin,true insulin,insulin,c-peptide and glucose were measured in all the subjects.Results 1.Levels of fasting proinsulin,c-peptide, glucose, insulin, true insulin and homeostasis insulin resistance in obese children with IGT showed significant difference compared with NGT (P

AIM　To study the protective effect of Gn-3 (a stilbene polymer isolated from Gnetum parvifolium) against liver injury induced by CCl4, N-acetyl-p-aminophenol (APAP) and Bacillus Calmette-Guerin (BCG) plus bacterial lipopolysaccharide (LPS) in mice. METHODS　The experimental model of liver injury were induced by 0.1% CCl4 ip (10 mL*kg-1*d-1 for 3d), APAP ip (150 mg*kg-1) or BCG (5 mg) plus LPS (7.5 μg) in mice. The levels of ALT in serum, MDA and GSH in liver tissues were detected. The histopathologic changes were observed by light microscope. RESULTS　Gn-3 was shown to markedly reduce the elevated serum ALT levels, liver tissue MDA and improve the histopathological changes in all the three experimental liver injury models. No effect of Gn-3 was observed on the liver GSH level in liver injury mice. CONCLUSION　Gn-3 was found to inhibit the development of liver injury caused by CCl4, APAP, or BCG plus LPS. This means that Gn-3 has liver protective effects.

Objective To investigate the efficacy of peritoneal dialysis(PD) in the children with complex congenital heart disease after surgery.Methods 65 children with complex congenital heart disease were divided into group A(33 cases) and group B(32 cases).Group A was given PD when diuretics or urine output was less than 0.5ml per hour,while group B was given PD when urine output was less than 0.5ml per hour after 6h.The survival effect and indicators of PD before and after treatment were observed.Results The effective rate of group A (84.85％ ) was significantly better than group B ( 53.12％ ) ( x2 =5.18,P ＜ 0.05 ).The fatality rate of group A (9.09％ ) was significantly lower than group B ( 18.75％ ) ( x2 =5.32,P ＜ 0.05 ).The renal function was significantly improved.Urine output increased to the normal level,serum potassium,blood urea nitrogen,serum creatinine concentration were effectively controlled,the changes of indicators had significant differences before and after PD (t =5.22,3.46,46,4.89,4.77,all P ＜ 0.05).Conclusion PD was an effective support method for heart,renal insufficiency after the surgery of complex congenital heart disease,and it had good clinical effect for early application.

Objective:To investigate the significance of CT imaging features in the diagnosis of first-episode paranoid schizophrenia.Methods:Forty-five patients with first-episode paranoid schizophrenia admitted to Shaoxing 7 th People's Hospital from January 2018 to January 2019 were included in the study group. An additional 40 healthy controls who received health examination were included in the control group. All participants underwent head CT scans and CT values of cerebral lobes were measured. CT imaging features of first-episode paranoid schizophrenia were analyzed. The recurrence rate of paranoid schizophrenia was calculated. The diagnostic effect of CT imaging on paranoid schizophrenia was evaluated. Results:The CT value of the frontal lobe in the study group was significantly lower than that in the control group [(33.1 ± 1.4) HU vs. (36.9 ± 2.1) HU, t = 9.914, P < 0.001]. The proportions of patients having ventricular enlargement, sulcus widening, arachnoid cyst and cisterna magna in the study group were 51.1%, 24.4%, 31.1% and 20.0% respectively, which were significantly higher than 5.5%, 2.5%, 2.5% and 2.5% respectively in the control group ( χ2 = 21.688, 8.411, 11.928, 4.675, all P < 0.05). The recurrence rate of paranoid schizophrenia in the study group was 22.2% (10/45). The CT value of the left and right frontal lobe in patients with recurrent paranoid schizophrenia was (32.1 ± 1.7) HU and (32.5 ± 1.6) HU respectively, which was significantly lower than (35.0 ± 1.9) HU and (34.9 ± 1.7) HU in patients without recurrent paranoid schizophrenia ( t = 4.348 and 3.985, both P < 0.001). Conclusion:Patients with first-episode paranoid schizophrenia have brain structural abnormalities, as manifested by ventricular enlargement, sulcus widening, arachnoid cyst, and cisterna magna. CT imaging features are of great value in the diagnosis of first-episode paranoid schizophrenia. It deserves wide popularization and has a great innovation value.

Thirty-six cases of delayed tramatic intracranial hematomas are reported in this paper. Among them 9, 5, 10 and 12 cases were epidural, subdural, intracerebral and multiple hematomas, respectively. The initial CT scans showed normal or brain contusions accompanied by a Me hemorrhage in 23 patients, and delayed intracranial hematomas developed after the earlier neurosurgical operations for evacuations of another traumatic mass lessions for urgent decompressions in 13 patients. Delayed hematomas occurred mostly in the acute stage of head injuries and most patients were impacted occipitally. Deterioration of consciousness was the most important manifestation for diagnosis. The responsible mechanisms of delayed intracranial hematomas are investigated and the indications of repeat CT scans or surgery for its early diagnosis are Droposed.

0.05).Conclusion The patients with CFS show a disorder of circadian rhythm.However,each index of CFS has no significant difference on the overall level.The imbalance of circadian rhythm is the pathologic characteristic of CFS.

Objective To identify and compare melanin distribution in iris and skin tissues of rabbits from four breeds including WHBE rabbit.Methods Ferrous sulphate staining was performed for iris and skin tissue of rabbits from different breeds.Results It showed dark green staining in both iris stroma and iris pigment epithelium of WHBE rabbit, while light green staining was observed in its follicles.Conclusion The results of histologic evaluations provide some clues to the future research on mechanism of WHBE rabbit phenotype mutation.

Aim: Synthesized N-acylated chitosan(NAC) was used to anchor on the surface of plain docetaxel li-posomes( PDL) in order to to sustain drug release. Methods; NAC of low substitution degrees were prepared using hexanoic(C_6), lauric( C_(12)), and palmitic( C_(16)) anhydrides. W-palmitoyl chitosan was chosen to anchor the do-cetaxel liposomes. In vitro release profiles of conventional liposmes and the anchored liposomes was compared. Results: Hexanoic(C_6), lauric( C_(12)), and palmitic( C_(16)) -branched chitosans were synthesized. It was found that N-acylated chitosan-anchored DXL liposomes (NDL) increase stabilities of docetaxel liposomes. 70% of docetaxel was released from PDL in 24 hours but 39% from NDL Conclusion: Liposomes anchored by the low substituted N-acylated chitosan could decrease the drug release.
