Objective To discuss the clinical characteristics of diagnosis and treatment of primary gastric malignant lymphoma (PGML). Method The data from 34 PGML medical records were reviewed retrospectively between January 2001 and May 2008. Results There were 23 cases of B-cell malignant lymphoma, 7 cases of T-cell malignant lymphoma, and 4 cases of non-B and non-T small cell lymphoma. Confirmed by pathology, 14 cases of them had metastasis to lymphoid nodes and 5 cases had invaded the organs nearby. All of these 34 cases had gastroendoscopy before operation. Conclusions PGML has no specific manifestation, and the definitely diagnostic rate of gastroendoscopy is low. The surgical resection is the major therapy.Operative pattern,the size of tumor,pathological stage can predicate the prognosis for PGML.

An in vitro detection method of the gastrointestinal absorption of Pilose Antler protein was established for mixed protein activity. Five bands of protein with molecular weight of 17.8-160 kD derived from the Pilose Antler were extracted and sufficiently labeled with FITC (FITC-PE). The stability and variation of FITC-PE in gastrointestinal circumstances were detected by native polyacrylamide gel electrophoresis and confocal laser scanning microscope. Results showed that the main component of FITC-PE kept invariant after being reacted with artificial gastric fluid and artificial intestinal fluid. The fluorescence signal was detected 20 min after administration in the valgus intestinal purse experiment, and three kinds of protein, with molecular weight of 45, 25, and 17.8 kD, were detected in the mixture of absorbent protein. The research laid the foundation for the further in vivo study of Pilose Antler protein. Meanwhile, it would be an in vitro screening method for the absorption, distribution and metabolism of mixed protein from traditional Chinese medicine.

To evaluate the neuroprotective effect of nerve growth factor ( NGF ) on acute angle-closure glaucoma patients after trabeculetomy.METHODS: Patients with viral keratitis who underwent trabeculectomy in treatment of acute angle - closure glaucoma in Xiamen Eye Center of Xiamen University from December 2011 to October 2013 were selected and completed the treatment, 61 eyes of 45 cases were followed up. The treatment group of 23 cases (32 eyes) with acute angle-closure glaucoma patients were treated by NGF gel for 3mo after trabeculetomy, while in the control group 22 cases (29 eyes) were treated by normal saline replaced NGF. All patients were followed up for at least 12mo, visual acuity, perimetry, retinal nerve fiber layer ( RNFL) thickness and cup/disc ratio of the patients were followed up during the treatment. The safety of topical use of NGF gel was also evaluated.RESULTS:ln all patients, the intraocular pressure ( lOP) was successfully controlled under 21mmHg and the visual acuity was markedly increased in the affected eye after trabeculectomy. Compared with control group, the postoperative lOP and visual acuity had no significant differences in treatment group (P>0. 05). The average light sensitivity of perimetry and mean defect were better than that in control group postoperative 6 and 12mo; The results of optical coherent tomography ( OCT ) and Heiderburg Retina Tomography ( HRT )-Ⅲ showed that RNFL thickness was significantly greater than that in control group, while cup/disc ratio significantly less than that in control group postoperative 6 and 12mo. Ocular surface damage, corneal endothelium to reduce and other eye complication were no observed in treatment group.CONCLUSlON:Acute angle-closure glaucoma treated by NGF gel after operation is effective and safe.

BACKGROUNDCyclic adenosine monophosphate (cAMP) could activate chloride channels in bovine ciliary body and trigger an increase in the ionic current (short-circuit current, Isc) across the ciliary processes in pigs. The purpose of this study was to investigate how cAMP modulates Isc in isolated human ciliary processes and the possible involvement of chloride transport across the tissue in cAMP-induced Isc change.
METHODSIn an Ussing-type chamber system, the Isc changes induced by the cAMP analogue 8-bromo-cAMP and an adenylyl cyclase activator forskolin in isolated human ciliary processes were assessed. The involvement of Cl(-) component in the bath solution was investigated. The effect of Cl(-) channel (10 µmol/L niflumic acid and 1 mmol/L 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS)), K(+) channel (10 mmol/L tetraethylammonium chloride (TEA)), or Na(+) channel blockers (1 mmol/L amiloride) on 8-bromo-cAMP-induced Isc change was also studied.
RESULTSDose-dependently, 8-bromo-cAMP (10 nmol/L-30 µmol/L) or forskolin (10 nmol/L-3 µmol/L) increased Isc across the ciliary processes with an increase in negative potential difference on the non-pigmented epithelium (NPE) side of the tissue. Isc increase induced by 8-bromo-cAMP was more pronounced when the drug was applied on the NPE side than on the pigmented epithelium side. When the tissue was bathed in low Cl(-) solutions, the Isc increase was significantly inhibited. Finally, niflumic acid and DIDS, but not TEA or amiloride, significantly prevented the Isc increase induced by 8-bromo-cAMP.
CONCLUSIONScAMP stimulates stroma-to-aqueous anionic transport in isolated human ciliary processes. Chloride is likely to be among the ions, the transportation of which across the tissue is triggered by cAMP, suggesting the potential role of cAMP in the process of aqueous humor formation in human eyes.

"Mistreatment by warming therapy" refers to various symptoms/syndromes caused by improper use of fire methods mentioned in Treatise on Febrile Diseases, which are similar to damaged yin induced fire-heat syndrome (injury of yin, consumption of qi, loss of yin, consumption of body fluid) manifested after radiotherapy and/or chemotherapy in modern clinics. Better efficacy was obtained in treating various symptoms/syndromes by using nourishing yin purging fire method. In this paper authors focuses on exploring guiding significance of using "Mistreatment by warming therapy" in treating non-small cell lung cancer (NSCLC).

Objective To investigated the possible roles of IL-18 in HBV infection, and the expression of IL-18 in the peripheral blood mononuclear cells (PBMC) of chronic hepatitis B. Methods In 15 cases of asymptomatic carriers, 30 cases of active and remissive phases of chronic hepatitis and 10 healthy individuals (as normal controls), IL-18 expression in PBMC were quantitatively analyzed with flow cytometric immunological method. The PBMC were separated routinely and stimulated with LPS (SIGMA) and Monensin (SIGMA) for 6 hours. Then the cells were harvested and fixed by PBS/4% paraformaldehyde. The treated cells were stored in liquid nitrogen for detection later. After immunologic stain, the expression of IL-18 in PBMC were examined by flow cytometry. Results ① IL-18 was the lowest in asymptomatic carriers. It was fewer in remissive phase than in normal controls (P<0.01).There was no difference between active phase and normal controls(P=0.25).②Within the group of active phase, IL-18 was significantly different between each grade of inflammatory activity(P<0.01),and correlated with serum ALT positively(r=0.63,P<0.01). Conclusion IL-18 may relate to disease activity and the inflammation of liver.

Objective To investigate the characteristic of P30o event-related potentials(ERP) of impulsive behavior in heroin addicts.Methods The Iowa gambling task (IGT) were performed by using the paradigm for psychological experiment both in heroin addiction group (HA group) and health control group (HC group),the inspection of electroencephalography were underwent in all the subjects concurrently.Following the collection of data of ERP,amplitude and latency of P300 were compared between the two groups,and then the relationship betweenamplitude or latency of P300 and the results of Barratt impulsiveness scale were analyzed separately.Results Compared to HC group,BIS score as well as the numbers of high frequency loss cards were significantly higher in HA group ( HA:75.12 ± 12.49,91.14 ± 21.35 ; HC:66.54 ± 8.61,73.71 ± 18.91 ; P < 0.05 ),while the both two groups had visible waveforms of P30o,and the amplitude and latency were markedly lower ( HA:4.92 ± 1.14,293.43 ± 36.21 ; HC:7.65 ± 1.59,332.68 ± 40.15 ; P < 0.05 ) and were negatively associated with BIS score in HA group( r =-0.76,-0.52,P< 0.05).Logistic regression results showed that the scores of BIS-11 were related to amplitude of P30o merely( P < 0.05 ).Conclusion Impulsive behavior can be observed from the abnormal characteristic of the P300 event-related potential of impulsive behavior in heroin addicts,which may partly contribute to both addiction and relapse of heroin addict.
