Aim To study the effect of the total flavonoids of turpinia arguta seen (TFS) on immune function of rats with adjuvant arthritis. Methods Adjuvant arthritis (AA) was induced on d0 by intradermal injection of Complete Freund′s Adjuvant (FCA), containing 10 mg heat-inactive BCG in 1ml paraffin oil. On d 28 after immunization, AA rats were killed by cervical decollation. Immune cells (splenocytes and peritoneal macrophages) were obtained, then cultured in vitro with TFS. Some immune indexes were detected respectively such as the splenocytes proliferation and the productions of IL-1 and IL-2 were measured by the method of cell proliferation, the production of prostaglandin E2 was determined by radioimmunoassay. Results Compared with normal groups, the response of splenocytes to ConA and LPS was lowered, IL-2 syn-thesis was decreased, and IL-1 and PGE_2 released from PM? were elevated. TFS (10~ -8 ~10~ -4 mg?L~ -1 ) not only increased splenocytes proliferation, which induced by ConA and LPS, and IL-2 production of splenocytes, but also reduced the elevated productions of IL-1 and PGE_2 released from peritoned macrophate in AA rats in vitro. Conculsion TFS could adjust abnormal immune function in AA rats.

OBJECTIVEX-linked adrenoleukodystrophy (ALD) is a genetically determined disorder that involves the nervous system white matter, axons, adrenal cortex and testes. The typical clinical manifestations are progressive psychomotor regression, vision and/or auditory impairment and adrenal insufficiency. The clinical manifestation, biochemical change and genetic counseling work of X-linked ALD were analyzed.

METHODSThe clinical features of 29 cases with ALD were summarized and analyzed, including symptoms and signs, measurement of blood very long chain fatty acids (VLCFA), adrenal function, cranial magnetic resonance imaging (MRI) and pedigree investigation.

RESULTSAmong these 29 cases, the clinical phenotype could be classified into childhood cerebral (22 cases), adolescent cerebral (4 cases), adrenomyeloneuropathic (1 case), Addison's disease (1 case) and asymptomatic or presymptomatic (1 case) types. Nine of them had positive family history. Pedigree investigation was consistent with typical sex-linked recessive inheritance. There were 45 ALD patients in these 29 pedigrees. The neurological manifestations varied among members of the same family. Nine cases died during follow up. The causes of death were central respiratory failure or other complications of ALD and so on. Laboratory tests demonstrated abnormally high plasma levels of VLCFA in ALD patients; MRI demonstrated symmetric butterfly-like low T(1) and high T(2) signals in the parieto-occipital white matter. The impairment in the splenium of corpus callosum made the bilateral lesion region converge into one. It could progress anteriorly and injure the bilateral posterior limb of internal capsule and the temporal lobe, and could injure the brainstem inferiorly. Following intravenous injection of contrast material, thin stripe of lacelike enhancement could be observed.

CONCLUSIONSThe atypical initial symptom of ALD was seizures. The MRI showed abnormal signal in the cerebellar white matter. This disease can influence the normal development of children, this was more pronounced in the childhood cerebral ALD type. It tended to progress rapidly with dementia, vegetative state or death. Since antenatal diagnostic method is available now, emphasis should be made on the antenatal examination in order to make an early diagnosis and abort pregnancy if necessary.

OBJECTIVETo investigate clinicopathological and immunohistochemical features of 31 cases of oral teratoid cyst.

METHODSThirty-one cases of oral teratoid cyst according with Meyer's diagnosis criteria were retrospectively studied and their histochemistry and immunohistochemistry were performed from the files of Department of Pathology, School of Stomatology, Wuhan University between 1963 and 2003.

RESULTSTwenty-seven cases (87.10%) were children, and twenty-four cases were congenital. The ratio of male-to-female was 1:0.55, and the affected sites were floor of mouth (22 cases) and tongue (8 cases). Clinical findings were nonspecific, and prognosis was good following complete excision. Histology indicated that squamous, respiratory and/or gastrointestinal epithelium consistiuted basic structure of teratoid cyst in addition to simple cuboidal epithelium in 8 cases. Antibody against AE1/AE3 was strongly expressed and CK16 was weak in four types of epithelial lining of oral teratoid cyst. Expression of AE1, CK7, 8/18, 19 varied in superficial, suprabasal and basal cells of squamous epithelium but were strong in respiratory, gastrointestinal and simple columnar epithelium; only gastrointestinal epithelium expressed CK20 heterogeneously.

CONCLUSIONSOral teratoid cyst showed the highest incidence in children, and floor of mouth and tongue were mostly affected sites. Features of histology were complex, and immunohistochemistry indicated that epithelium of oral teratoid cyst shared similar patterns of cytokeratin with counterpart of normal tissues, showing different origin and differentiation of epithelial lining of the present cyst.

Objective To study the mechanism of organic anion trans-porting polypeptide1B1 (OATP1B1) and cytochrome P2C9 (CYP2C9 ) genetic polymorphism effect on the metabolism and transport of fluvasta-tin.Methods Build OATP1B1*1a,*5and*15 recombinant plasmid model and CYP2C9*1,*3 recombinant enzyme model to compare up-take and enzymatic kinetic parameters of fluvastatin in different models.Results The fluvastatin intake of OATP1B1*5 gene, OATP1B1*15 gene, OATP1B1*1a gene are ( 3.27 ±0.53 ), ( 6.88 ±2.01 ), (6.32 ±1.23 ) pmol· min-1· mg-1 protein.Compared with OATP1B1*1a, OATP1 B1*5 reduces the transport capacity of fluvastatin ( P <0.05 ) and OATP1B1*15 gene increases (P<0.05).The CLintof CYP2C9*3 and CYP2 C9*1 metabolizing fluvastatin are 0.42 , 1.25 ( P<0.05 ).The activities of CYP2C9*3 are lower than CYP2C9*1.Conclusion The OATP1B1 521 site and the CYP2C9 359 site might be the molecular action site of transport fluvastatin.Therefore , more attention should be payed in clinical applications to prevent damage caused by OATP 1B1 and CYP3A4 genetic polymorphism.

Objective: The current study was designed to observe the clinical results of late course accelerated hyperfractionation(LCAH) radiotherapy in Stage I- II nasopharyngeal carcinoma(NPC) patients. Methods: A total of 108 patients with Stage I- II NPC were divided at random into two groups: conventional fractionation(CF) and LCAH, The patients in CF group received a fraction of 2 Gy daily, 5 days per week, to total dose of 70 Gy/7weeks. The patients in LCAH group were treated with the same fractionation as CF group to dose of 36- 40 Gy, and followed by late course accelerated hyperfractionation radiotherapy: 1.5 Gy, twice daily, with the interval of 6 hours between fractions, to total dose of 69 Gy/6weeks. Results: The complete response rate in the nasopharynx was 89.47％ in the LCAHR and 70.97％ in the CFR at the end of the course (P=0.05). Disappeared rate of cervical lesion was not significant different between two groups (P >0.05). The survival rates of 1, 2, and 3-year were 98.13％ ,93.95％ ,90.87％ in the LCAH and 96.12％ ,80.97％ ,78.55％ in the CF, respectively (P=0.06). There was no significant difference in radiation reaction and sequela between two groups( P >0.05) . Conclusion: The clinical results of LCAH radiotherapy in Stage I- II NPC may be better than conventional fractionation radiotherapy, is worth further study.

OBJECTIVETo investigate the resection range of mesorectum and rectum below the inferior margin of tumor for the total mesorectum excision (TME) in middle-low rectal cancer.

METHODSSixty patients were enrolled in the study. After TME operation, serial 5 mm interval sections were made in specimens of middle-low rectal cancer. The retrograde metastasis of rectal cancer was observed by routine HE staining.

RESULTSThe phenomena of retrograde metastasis in mesorectum were found in 15 cases, and the distance of retrograde metastasis was 0.5-4.0(2.47+/-1.06) cm, which was correlated with Dukes stage, lymph node metastasis and histological differentiation. The retrograde metastases in bowel were found in 11 cases, and the distance of retrograde metastasis was 0.5-4.0 (1.64+/-1.16) cm, which was correlated with histological differentiation.

CONCLUSIONSThe distal mesorectum should be resected at least 4 cm when TME is carried out, and the distal bowel at least 2.5 cm. More than 5 cm mesorectum and bowel should be resected when advanced Dukes stage, extensive lymph node metastasis and poor histological differentiation occurred.

OBJECTIVETo make prenatal dignosis of X-linked adrenoleukodystrophy (ALD) for the prevention of the disease.

METHODSEighteen amniocenteses were performed on 17 suspected carriers of X-ALD during 18-30 gestation weeks. The very long chain fatty acids (VLCFAs) levels of cultured amniocytes were tested by gas chromatography-mass spectrometry (GC/MS). The plasma VLCFAs levels were measured in 8 of the 18 prenatal diagnosed children when they were born or after abortion. ABCD1 gene mutation analysis was carried out in 8 cases by PCR and sequencing. ALDP of amniocytes was tested by Western blotting in 2 cases from a family, one female, another male, and the VLCFAs of cultured amniocytes were increased in both of them.

RESULTSAmong the 18 fetuses, 10 were males and 8 were females. The VLCFAs levels of the cultured amniocytes were increased in 3 males and 4 females. The postnatal plasma VLCFAs were normal in 5 cases with normal VLCFAs levels of amniocytes, and increased in 3 cases with high VLCFAs levels of amniocytes. ABCD1 gene mutations were found in 4 cases with high VLCFAs levels of amniocytes, no mutation was found in other 4 cases with normal VLCFAs levels of amniocytes. ALDP of amniocytes could be detected in the female with high VLCFAs levels of amniocytes, and it could not be detected in the male with high VLCFAs levels of amniocytes. Three male fetuses with high VLCFAs levels of amniocytes were aborted. The others who were born were normal clinically so far.

CONCLUSIONThe prenatal diagnosis is very important for the prevention of ALD. Amniocyte VLCFAs level analysis combined with ABCD1 gene mutation analysis and ALDP test could make a proper prenatal diagnosis.

OBJECTIVEX-linked adrenoleukodystrophy (X-ALD) is the most common peroxisomal disorder characterized by progressive demyelination of the central nervous system, adrenal cortex insufficiency and accumulation of saturated very long chain fatty acids (VLCFAs) in tissues and body fluids due to the impaired beta-oxidation in peroxisomes. X-ALD shows a wide range of phenotypic variation. Childhood cerebral form (CCER) is the most common phenotype with severe neurological symptoms and often the average interval from onset to total disability or death is 3 years. So far no effective treatment is available for the underlying defect. Screening for carriers of mutated relevant gene and prenatal diagnosis are very important for the prevention of the disease. In this study, the authors explored the method of carrier screening and prenatal diagnosis of X-ALD.

METHODSThe plasma VLCFAs levels of 83 suspected carriers for ALD were determined by using GC/MS and ABCD1 gene mutational analysis was performed in 31 of them. Amniocentesis was performed in 9 suspected carriers for ALD during 18 - 30 gestational weeks. The VLCFAs level of cultured amniocytes was tested with GC/MS. ABCD1 gene mutational analysis was performed on two cases (one was a male and the other a female) whose VLCFAs levels of amniocytes were found elevated. The plasma VLCFAs levels were measured in five of the nine prenatally diagnosed children when they were 1 day to 3.5 years old.

RESULTSFifty-one of 83 suspected carriers had high plasma VLCFAs levels; 29 of 31 suspected carriers showed ABCD1 gene mutation. Among the nine fetuses, four were males and five were females. The VLCFAs levels of the cultured amniocytes were high in two cases, one was female and the other a male. ABCD1 gene mutational analysis of these two cases showed a 871G > A (E291K) mutation and a 726G > A (W242X) mutation, respectively, which confirmed the biochemical result. The VLCFAs levels were normal in the rest of cases and five of them were confirmed by postnatal plasma VLCFAs assay.

CONCLUSIONThe carrier screening and prenatal diagnosis are very important for prevention of the X-ALD. Only the combined use of plasma VLCFAs level analysis and ABCD1 gene mutational analysis could detect X-ALD carriers correctly. ABCD1 gene mutational analysis and postnatal plasma VLCFAs level test verified that amniocytes VLCFAs level analysis is a reliable prenatal diagnostic method for this disease.

OBJECTIVETo evaluate the efficacy and safety of the Qingrelishi-category Chinese medicine (for dispelling heat and resolving dampness) in the treatment of chronic prostatitis.

METHODSRandomized clinical trials or controlled clinical trials comparing Qingrelishi with plant america, other herbal medicine and Western medicine in the treatment of chronic prostatitis were identified by electronic and manual retrieval and analysis. The methodological quality of the included trials was assessed and Meta-analysis was performed with Revman 4. 2 software.

RESULTSForty-four randomized clinical trials or controlled clinical trials (n=5746) were identified. The methodological quality ranked high in three double-blind trials and the others ranked low. Meta-analysis indicated that Qingrelishi was more effective than Nankangpian( RR 1.22, 95% CI 1.10-1.35) and Prostate( RR 1.26, 95% CI 1.13-1.41) in the treatment of chronic prostatitis. Subgroup analysis revealed that Qingrelishi was more effective than Qianliekang (RR 1.32, 95% CI 1.19-1.45) and quinolones antibiotic (RR 1.34, 95% CI 1.15-1.57). There were no significant differences in efficacy either between Qingrelishi and a-receptor blocker and Puleanpian or between Qingrelishi plus quinolone antibiotics and quinolone antibiotics alone. Eighteen articles reported side effects and no serious adverse events were reported.

CONCLUSIONQingrelishi may be effective in the treatment of chronic prostatitis. However, the evidence is not strong due to the generally low methodological quality and the variations of the herbs. More randomized clinical trials are required.
