Objective To investigate the changes and clinical significance of serum lactate dehydrogenase (LDH),creatine kinase (CK),glutamate pyruvate transaminase (AST),and cerebrospinal fluid lactate dehydrogenase (CSF LDH) in adult patients with acute central nervous system infection.Methods The levels of myocardial enzymes (AST,LDH,and CK) in serum of 96 adult patients with acute intracranial infection in 7days and 39 healthy people were measured by Beckman automatic biochemical analyzer and enzyme rate assay,and CSF LDH level in 96 patients were measured simultaneously.Results (1) The serum myocardial enzymes (LDH,CK,and AST) of intracranial infection group (47 cases with viral encephalitis,30 cases with tuberculous meningitis,and 19 cases with purulent encephalitis) were significantly higher than those of normal control group (P ＜0.01).(2)The myocardial enzymes (LDH,and AST ) of patients with cerebral functional disorder were significantly higher than those of patients with normal cerebral function (P ＜0.05).(3)The levels of serum AST,LDH,and CK in the virus encephalitis group,serum AST and LDH in the purulent encephalitis group,and serum LDH in the tuberculous meningitis group were significantly higher than those in the control group (P ＜ 0.01).The CSF LDH level in the viral meningitis group was prominently lower than that in the tuberculous encephalitis group and purulent encephalitis group,respectively (P ＜0.01).(4) No correlations were found between CSF LDH and serum myocardial enzymes (P ＞0.05).Conclusions (1)There is significant change in the levels of serum LDH,CK,AST,and CSF LDH of adult patients with acute intracranial infection,especially in infected patients with cerebral functional disorder,and the change of LDH is the most obvious.(2)The levels of serum myocardial enzymes and CSF LDH are helpful to the differential diagnosis of intracranial infection in early stage,and judging the severity of the illness.

OBJECTIVESTo evaluate the effects of varicocele (VC) on IL-1 and NO levels in testes of rats with VC.

METHODSMale adult Wistar rats were divided into two groups randomly, VC group (n = 30) and pseudo-operation group (n = 20), and the levels of IL-1 and NO in the testes were determined and compared.

RESULTSThe levels of IL-1 and No of left tests in VC group were higher than those in pseudo-operation group, respectively(P < 0.01). While the levels of IL-1 and NO of right testes between two groups were not significantly different (P > 0.05). More over, the level of IL-1 correlated significantly with that of NO(r = 0.572, P < 0.01).

CONCLUSIONSThe results revealed that the changes of IL-1 and NO levels in the testes of rats with VC might be the reason which caused testes damage, disturbance of spermatogenesis and even infertility.

OBJECTIVETo study the effects of the extensive resection of the tumor-loading segment and artificial humerus head replacement combined with perioperative rehabilitation for the treatment of stage II to III giant cell tumor of bone in the proximal humerus.

METHODSFrom March 2007 to March 2010, 7 patients with stage II to III giant cell tumor of bone in the proximal humerus were treated. Among the patients, 3 patients were male and 4 patients were female with a mean age of 34.6 years (ranged, 18 to 49 years). The mean course of disease was 19 months (ranged, 6 to 35 months). All the patients were confirmed to suffer stage II to III giant cell tumor of bone in the proximal humerus by pathology and X-ray examinations. Clinical manifestations of the patients included persistence aggravated pain of the shoulder, swelling in the proximate arm with obviously tenderness, activity limited of the joint. All the patients were treated with extensive resection of the tumor-loading segment and artificial humerus head replacement combined with perioperative rehabilitation. CMS and OSIS score system were used to evaluate shoulder function and shoulder stability.

RESULTSAll the patients were followed up, and the duration ranged from 14 to 35 months, with an average of 17 months. There were no serious complications or recurrence in all cases. One year after the surgery CMS and OSIS score system were 70.7 scores (ranged,63 to 82 scores) and 25.1 scores (ranged, 18 to 29 scores) respectively. According to evaluation for shoulder function, 2 patients got an excellent result and 5 good. According to evaluation of shoulder stability, 1 patient got an excellent result and 6 good.

CONCLUSIONExtensive resection of the tumor-loading segment and artificial humerus head replacement combined with perioperative rehabilitation for the treatment of stage II to III giant cell tumor of bone in the proximal humerus would not only preserve the upper extremity but also preserve the function of upper extremity.

OBJECTIVETo investigate the feasibility of peptide mass fingerprinting for non-invasive differential diagnosis of IgA nephropathy (IgAN) from the non-IgA nephropathy (IgAN).?

METHODSAccording to the results of renal biopsy, 56 patients were divided into IgAN group (n=28) and non-IgAN group (n=28), and peptide mass fingerprints were acquired from these patients using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).

RESULTSNine different peptides were identified between IgAN and non-IgAN. The two most distinctive differentially expressed peptides, with peptide peak values of 4476.46 and 1968.10, showed area under curve values of 86.18% and 79.77%. Principal component analysis demonstrated that the accumulated explained variance of the first 8 differential peptides reached 95%, suggesting the feasibility of differential diagnosis of IgAN from non-IgAN. Comparison with the Matrix protein database identified the peptide with a relative molecular mass of 5338.08 as a fragment of mucin 4 inform and the 2082.77 peptide as fragment of α1-II type collagen inform.

CONCLUSIONMALDI-TOF MS is feasible for differential diagnosis of IgAN and non-IgAN and also has great potentials in the classification of the subtypes of other systemic diseases.

OBJECTIVETo study the effect of Jinguo Weikang Capsule [see text] on the gene expression of H-ras, epidermal growth factor receptor (EGFR), P53 and C-myc of the gastric mucosa in rats with gastric precancerous lesions, and to investigate the action mechanism of JWC on gastric precancerous lesions.

METHODSA rat model with paratypical proliferation of the gastric epithelium mucosa was established by using 60Co irradiation. Rats were divided into the normal group, model group, high-, medium-, low-dose JWC treatment groups, and the vitacoenzyme control group, and were treated for 30 days. The expression of H-ras, EGFR, P53 and C-myc genes of the gastric mucosa was detected by using immunohistochemical methods.

RESULTSThe expression and over-expression rates of H-ras, EGFR, P53 and C-myc gene in the high-and medium-dose JWC treatment groups were significantly lower (P<0.05) as compared with those of the model group.

CONCLUSIONJWC can inhibit the expression of the H-ras, EGFR, P53 and C-myc genes expression of the gastric mucosa in rats, which may be one of mechanisms involved in suppressing or reversing gastric carcinogenesis.
