Clinicopathology is a clinical application technology of histomorphological examination on tissue biopsy specimens,gross sampling and slice,and a pathological diagnosis is obtained by combining with clinical manifestations,surgical findings,gross changes and the cell morphology change under the optical microscope and further immunohistochemistry and molecular biological detection on tissue sections,thus to accurately diagnose the disease and provide a reliable basis for pathological disease etiology,pathogenesis research,eye disease outcome and prognosis judgement.Ocular pathology was not only the gold standard of the diagnosis,but also a therapeutic tool for eye diseases.Ophthalmology is a surgery related clinical disciplines.In clinical work,we found that ignoring the pathological examination of resected tissue specimens is the primary cause of misdiagnosis and mistreatment of eye disease,diagnostic delays can also increase the disease deterioration and mortality risk.Ocular clinical and pathological examination is one of the specific measures to avoid misdiagnosis and mistreatment,it is suggested that ophthalmology clinicians pay attention to the pathological examination in order to carry out precise treatment of eye diseases.

Objective To review the characteristics of human defensin 5 (HD 5), including molecular structure, antibacterial activity and gene expression, and to show its development prospect as a new drug in the treatment of enterogenic infection. Methods The published papers about HD 5 were reviewed to summarize its research progress. Results Being a 3-5 KDa cationic peptide rich in cysteine and arginine, especially without glycosylated side chain, HD 5 plays its antibacterial role against positive and negative Gram's bacterium, fungi, spirochete, protozoan and enveloped virus with the special active center composed of three disulfide bonds. HD 5 encoding gene alpha defensin 5 (DEFA 5) localizes at the 8th chromosome P21 pter with 449 bp, which includes five pieces of sequence: 5′ untranslated region (1-40),signal peptide (41-97), propiece (98-226), mature peptide (227-322),and Poly A (433-438).Conclusion As a broad spectrum and effective endogenous antimicrobial peptide, HD 5 would be a promising alternative peptide against enterogenic infection if the accessibility to its mass production is settled.

Objective To investigate the disease categories of the upper alimentary tract and the ratio of Hp infection in countryside children. Methods 96 children with complaint in upper digestive tracts underwent gastro-scope and in each patient,a piece of mueosal tissue in sinus ventrieuli was taken out to perform Hp urase test. Results All of the 96 children were detected abnormal including chronic superficial gastritis (n = 63), ulcer of duodenal bulb(n = 13) ,enteritis of duodenal bulb(n =7) ,gastritis with bile reflux(n =4) ,erosive gastritis(n =2) ,ascariasis (n = 6), aneylestomiasis(n = 3). The positive rate was 100%. 49/96 (51%) were positive in Hp test, including 36/ 63(57.1%) of chronic gastritis ,10/13(76.9%) of ulcer of duodenal bulb,2/7 (28.6%) of enteritis of duodenum. Hp were positive in 11 (35.5%) in the group with age range from 3 to 6 years old and positive in 38 (58.5%) in the group with age range from 7 to 12 years old. Conclusion Chronic superficial gastritis and ulcer of duodenal bulb were the main findings in gastrescopy in children with a upper digestive tract complaint. Hp infection ratio was highest in patients with ulcer of duodenal bulb in our study, and followed by the chronic gastritis. And the infection rate in-creased with the age increased.

Angiotensin II (Ang II ) is an effector of rein-angiotensin system. Ang II receptors mediate its biological effects. An analysis of radioactive ligand demostrated that mammalian exists AT1 receptor and AT2 receptor subtype. AT1 receptor exists three isoforms, AT1A, AT1B and AT1c receptor subtype in rat and mouse. The AT3 and the AT4 subtype receptors had been cloned, but their structure and function were unknown. The AT1 receptor belongs to the superfamily of seven trans-membrane domain, G-protein-coupled receptors and was 20%~ 30% homologous to other G-protein-coupled receptors. The AT1 receptor mainly exists in vessel, heart and adrenal glands in adult animals. The AT2 receptor only has 32% amino acid sequences homologous to AT1 receptor and mainly exists in embronic tissue and intersti-tium. Recent studies have shown that the AT1 receptor may mediate most of the biological functionof Ang I . The AT1 receptor mediates promoting the expression of growth-related inducible transcription factors such as c-fos, c-jun and c-myc, and inducing myocardial cell hypertrophy, cardiac fibroblasts proliferation and interstitial collagen deposition. The AT1 receptor antagonist can reverse myocardial hypertrophy and collagen accumulation induced by hypertension, but the AT2 receptor antagonist can't. The biological function of the AT2 receptor is little known. The AT2 receptor may mediate inhibit on of growth factor-induced cell proliferation, oposite AT1 receptor-induced mi-togenic effect and induce apoptosis. The AT1 receptor and AT2 receptor subtype in myocardial tissue may regulate the genesis and development of myocardial remodeling in hypertension togather.

Objective It has been shown that ketamine attenuates cytokine production and release induced by endotoxin. The purpose of this study was to investigate the effects of diazepam and ketamine on inflammatory responses during early stage of burn. Methods BALB/C male mice weighing 20-25 g were randomly divided into 5 groups : (1) normal control group (n = 10); (2) burn control group received Ⅲ degree bums covering 15%-20% of the body surface (n = 10); (3) D-K group received intramuscular diazepam 0.4mg?kg-1 and ketamine 10 mg?kg-1 ( n = 10); (4) D + K pretreatment group received D + K 15 min before burn ( n = 10) and (5) D + K post-treatment group received D + K 15 min after burn ( n = 10) . Four hours after burn or anesthesia (D + K) the animals were sacrificed and blood was collected for determination of serum TNF-?, IL-1? and IL-10 concentrations (ELISA) and peritoneal macrophages were isolated for detection of glucocorticoid receptor (GR) by Western blotting. In addition peritoneal macrophages isolated from normal animals (group 1) and bum animals (group 2) were cultured with diazepam-ketamine for 1 h befor detection of GR.Results Serum TNF-?, IL-1? and IL-10 levels in group 2 were significantly higher than those in group 1. In group 4 and 5 serum TNF-?, IL-l? and IL-10 levels were significantly lower than those in group 2. In group 4 only serum IL-10 level whereas both serum IL-1? and IL-10 levels in group 5 were significantly higher than those in group 1. GR of peritoneal macrophage was significantly down regulated 4 h after bum (group 2) as compared with group 1. The level of GR in group 4 was significantly higher than that in group 2 but not significantly different from that in group 1; whereas the GR level in group 5 was significantly higher than that in group 2 but lower than that in group 1 and 4. There was no significant difference in GR expression after macrophages were cultured in vitro with diazepam and ketamine between normal or bum groups. Conclusion Diazepam-ketamine pretreatment can suppress cytokine release induced by severe bum. The expression of GR in peritoneal macrophages is significantly reduced by bum. Diazepam-ketamine given before or after bum can suppress the inflammatory response but have no direct effect on peritoneal macrophages.
