To study the influence of foreign plasmid DNA on spleen metabolism in immune-stimulated mice via the gastrointestinal tract. Mice were oral administered by pipette with 200?g of plasmid pcDNA3 and spleen were isolated at 4h and 18h after oral administration. Total RNA were extracted from spleen and spleen gene expression profile of Balb/c mice was analyzed by using Affymetrix oligonucleotide genechip after oral plasmid pcDNA3 administration. Functional cluster analysis was conducted by Genmapp and MAPPFinder software. By functional cluster analyzing the genes which were up-regulated more than twofolds, Genmapp results showed that plenty of metabolic pathway were induced in spleen after oral administration of plasmid pcDNA3. These metabolic process included purine metabolism, pyrimidine metabolism, protein synthesis, cholesterol synthesis, fatty acid synthesis, Glycolysis, TCA cycle and mitochondria oxidative phosphorylation pathway. The similar results also took place at 18h after oral administration. The result indicated that foreign plasmid DNA can modulate metabolism process in spleen of mice via the gastrointestinal tract, and may help understand the mechanism of action of foreign plasmid DNA uptaked via the gastrointestinal tract.

Objective To explore the clinical features and treatment of eosinophilic lymphoid granuloma(ELG) in children,in order to increase understanding of the disease.Methods Clinical features,laboratory examination,pathological examination,treatment and the-(rapeutic) effect of 5 patients with ELG were retrospectively studied,and the related literature were reviewed.Results Five cases were all boys.They all presented many subcutaneous swellings and lymphadenopathy.A case among them was associated with nephrotic syndrome,and 2 cases had the complication of eczema repeatedly,and 1 case ever had 2 times episodes of asthmatiform bronchitis.All of them had no hepatomegaly and splenomegaly,physically was well developed.Only chemotherapy was supplied to all the patients.During the course of therapy,4 cases among them recurred.After that,they were successfully treated with irradiation of lesion or cyclosporine(CsA).Conclusions ELG in children is as same as adult in clinicopathological features.It tends recur only with chemotherapy.We can get better curative effect with the synthetic treatment of chemotherapy,radiotherapy,operation or oral CsA and so on.

Objective To evaluate the clinical outcome of reconstruction of the superior peroneal retinaculum (SPR) by using a portion of Achilles’s tendon and suture anchors in the treatment of chronic peroneal tendon dislocation .Methods Seven patients in our hospital from January 2010 to January 2015 who underwent surgical reconstruction of SPR by using a portion of Achilles ’ s tendon and suture anchors were evaluated .The ankle ’ s range of motion ( ROM) and The American Orthopaedic Foot and Ankle Society ( AOFAS) ankle-hindfoot score were used to evaluate the clinical outcome .Results All 7 cases were followed up for 6 to 24 months,the average time was 14 months,with-out recurrence.The ankle’s ROM improved from (23.6 ±1.9) °preoperative to (30.0 ±1.5) °at the final follow-up,and the AOFAS An-kle Hindfoot Scale improved from (60.6 ±3.6) point preoperative to (93.6 ±3.9) point at the final follow-up.Conclusion Surgical re-construction of SPR by using a portion of Achilles ’ s tendon and suture anchors may be an effective alternative surgical method for chronic peroneal tendon dislocation .

To evaluate the clinical efficacy and safety of Qinghouyan lozenge in the treatment of acute pharyngitis due to Lung-heat and Yin-deficiency, and compare with Qinghouyan oral Liquid. Totally 144 subjects were enrolled and randomly divided into two groups (72 in the test group and 72 in the control group). The participants in the test group were given Qinghouyan lozenge for 5 days, and those in the control group were given Qinghouyan oral Liquid for 5 days. The effectiveness evaluation indexes were pharyngalgia/odynophagia disappearance rate, overall efficacy of TCM syndromes, TCM syndrome scores, and single syndrome and sign disappearance rate. During the test, the safety was evaluated by vital sign, lab examination indexes and adverse events. The results for the full analysis set showed that the couth disappearance rate, the incidence rate of TCM syndromes, and the throat/uvula congestion disappearance rate of the test group were higher than that of the control group (P < 0.05), with significant differences in the changes in syndrome scores between the two groups (P < 0.05). Altogether 3 adverse events were observed in the test group while 6 adverse events in the control group, without significant differences in the adverse event rate between the two groups (P < 0.05), serious abnormal laboratory examinations and vital signs. In conclusion, Qinghouyan lozenge has better efficacy in treatment of acute pharyngitis due to Lung-heat and Yin-deficiency than Qinghouyan oral liquid, with good safety.

Objective To explore the suitable range of PT-INR for Chinese people with acute deep venous thrombosis (DVT) treated by warfarin anticoagulation therapy. Methods Eighty seven DVT patients with indications to warfarin anticoagulation therapy were enrolled into the study and divide into two groups randomly. Patients from group A (n=47) took warfarin to adjust the PT-INR to range 1.7-2. 5,and patients from group B (n =40) took warfarin to adjust the PT-INR to range 2. 0-3. 0. The therapeutic effectiveness and the incidence of bleeding complications were compared between two groups. Results Forty-six patients (46/47,98%) had limb swelling symptoms relief in group A with one exception,which was diagnosed as pelvic tumor by ultrasonography,CT and tumor markers examination later. No patient underwent bleeding in group A Thirty eight patients (38/40,93%) had limb swelling symptoms relief in group group B with two exceptions,of which one case had Cockett syndrome and the other one had unknown aetiology. The total effective rate of group B was 95% . As to the complications of this group,3 patients had slight gum and nasal mucous membrane bleeding, 1 patient developed gastrointestinal bleeding. No patients had pulmonary embolism in both groups. Conclusion For Chinese people,anticoagulation therapy of acute deep venous thrombosis to adjust the range of PT-INR to 1.7-2. 5, shows good effectiveness and significantly reduced bleeding complications.

AlM: To describe the expression of hypoxia-inducible factor-1α ( HlF-1α) and erythropoietin ( EPO ) in rats' corneal and evaluate its potential effect on corneal neovascularization ( CNV) growth.
METHODS:The young SD rats (3mo) was chosen and randomly divided into 2 groups, which were experimental group and normal control group. CNV model was established by alkali burn, and the length and area of CNV was observed everyday after operation by slit lamp. After that, the expression of HlF-1α and EPO was measured by SABC and RT-PCR methods at 1, 3, 5, 7, and 14d after alkali burn. The data was analyzed by SPSS 20. 0.
RESULTS:The area of CNV was increasing at 1, 3, 5, 7, and 14d after alkali burn, and the peak point appear at 7d. The growth speed was decreased after 14d. SABC method told us that no HlF-1αand very tiny amount EPO was detected at normal rats' corneal. The expression of the two factors increased at 1d after alkali burn in corneal epithelium and endoderm. The results of RT - PCR showed that a few amounts of HlF-1α and EPO mRNA were detected at normal group. The expression of the two factors was increased at 3d after alkali burn, and the peak value was found at 7d, however, it was decreased at 14d. Statistical difference was found at different time (P<0. 05).
CONCLUSlON: HlF- 1α and EPO is closely related to CNV.

AIM: To study the characteristics of retinal detachment surgery after laser 　in situ　 keratomileusis (LASIK).METHODS: Eleven eyes of ten patients that experienced rhegmatogenous retinal detachment after LASIK procedure participated in the study. The characteristics of retinal detachment, management and complications after surgery were analyzed . RESULTS: Retinal detachment was characterized by the large percentage of multiple peripheral holes (73%) and giant tears (27%). All eyes underwent sclera buckling, and three of them combined with pars plana vitrectomy (PPV) and silicone oil tamponade. Silicone oil was removed after 1 month. Retina was reattached successfully at the first retinal detachment surgery in all eyes except one that succeeded at the fourth time. One eye of LASIK flap dehiscence and one eye of corneal subepithelial opacity occurred after surgery.CONCLUSION: Patients after LASIK should be carefully examined under pupillary dilation during follow-up. Sclera buckling is necessary to most retinal detachment after LASIK, and corneal protection is important in the treatment.
