AIM: To observe the efficacy of surgical excision combined with autologous limbus conjunctival flap transplantation in the treatment of pterygium accompanied with conjunctival cyst.METHODS: Totally 126 patients 188 eyes with pterygium were hospitalized in Department of Ophthalmology of Tongji Hospital of Huazhong University of Science and Technology during August 2013 and August 2015.The patients were divided into two groups: observation group (11 eyes of 11 patients) with pterygium accompanied with conjunctival cyst and control group (177 eyes of 115 patients) with primary pterygium.All patients underwent slit lamp microscope examination, anterior segment photography, and anterior segment optical coherence tomography(OCT).The size of pterygium was calculated by multiplying neck width and length of the covered corneal.All patients underwent excision combined with autologous conjunctival flap transplantation, and the resections were performed pathological section with hematoxylin and eosin staining.All patients were followed up postoperatively for 4-28mo.RESULTS: All cases in the observation group were confirmed by postoperative pathological examination.All cyst walls were complete, and containing single layer of epithelial cells.The mean size of pterygium of the observation group was 6.9±1.7mm2, and 6.3±1.8mm2 for the control group.There was no significant difference between the two groups (P>0.05).The mean postoperative healing time of observation group was 2.1±0.9d, and 1.9±0.8d for the control group.There was no significant difference between the two groups (P>0.05).Recurrence was seen in two eyes within the follow-up period in the control group, and no recurrence in the observation group.CONCLUSION: Surgical excision combined with autologous limbus conjunctival flap transplantation is a safe and effective treatment for pterygium accompanied with conjunctival cyst.

Objective To study the expression patterns of Th1 and Th2 cytokine genes in childhood acute idiopathic thrombocytopenic purpura(ITP) and its clinical value.Methods Peripheral blood samples from 30 patients with acute ITP before and after treatment (ITP group) and those from 20 normal healthy subjects (healthy control group) were collected (healthy control group),and reverse transcriptases polymerase chain reaction was performed to determine the mRNA expressions of Th1 and Th2 cytokine genes before and after treatment,which were compared with those of the health controls.Results The positive rate of expression levels of Th1 cytokine genes in samples from ITP patients (3.3％,3.3％) were significantly lower than those from healthy control group (all P ＜ 0.05) and increased to normal level after treatment(16.7％,23.3％).In contrast,Th2 cytokine genes (IL-4,IL-6,IL-10)in the samples from the ITP patients(33.3％,43.3％,40.0％) were significantly higher than those from the healthy control group (all P ＜0.05) and decreased after treatment(10.0％,23.3％,20.0％).Conclusions Such data indicate that ITP is a Th2 cell predominant autoimmune disease,and the abnormal immunity due to Th1/Th2 shift is significant in the pathogenesis of ITP.

OBJECTIVETo observe the effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis (CDSPHWDBS) on the expression of gastric mucosal heat shock protein 70 (HSP70) in chronic atrophic gastritis (CAG) patients.

METHODSA total of 100 CAG patients were assigned to the control group and the treatment group by random digit table, 50 in each group. Patients in the control group took Folic Acid Tablet 10 mg each time, 3 times per day. Those in the treatment group took CDSPHWDBS, 100 mL each time, once per day. The treatment course was 6 months for all. Clinical symptoms and signs, endoscopic and histopathological changes were observed before and after treatment in the two groups. The expression of gastric mucosal HSP70 in CAG patients was determined using SP immunohistochemistry. Data were collected by HPIAS-1 000 pathological graphic analysis system, and its expression semi-quantitatively analyzed.

RESULTSThe total effective rate of clinical Chinese medical symptoms and signs was 88. 0% (44/50 cases) in the treatment group and 56. 0% (28/50 cases) in the control group, with significant difference between the two groups (P <0. 01). The improvement rate of endoscopic manifestations such as congestion and edema, erosion, bile regurgitation, pale gastric mucosa, exposed blood vessels, particles proliferation in the treatment group were superior to those in the control group (P <0. 05). The total effective rate of atrophy was 80. 0% (40/50 cases) in the treatment group and 54. 0% (27/50 cases) in the control group, with significant difference between the two groups (P<0. 01). The effective rate of intestinal metaplasia was 75. 0% (12/16 cases) in the treatment group and 33.3% (5/15 cases) in the control group, with significant difference between the two groups (P < 0. 05). The optical density value of gastric mucosal HSP70 was significantly elevated in the two groups after treatment (both P <0. 05). It was higher in the treatment group than in the control group after treatment with significant difference (P <0. 01).

CONCLUSIONCDSPHWDBS had obvious effect in treatment of CAG and could improve pathological changes of precancerous lesions possibly by promoting the expression of gastric mucosal HSP70 in CAG patients.

OBJECTIVETo investigate the brain oxidative stress injury induced by nano-alumina particles in ICR mice.

METHODSSixty male ICR mice were randomly divided into 6 groups: control group, solvent control group, 100 mg/kg micro-alumina particles group, 3 groups exposed to nano-alumina particles at the doses of 50, 100 and 200 mg/kg. The mice were exposed by nasal drip for 30 days. Then levels of malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-PX) in brain tissues of mice were detected.

RESULTSThere was no difference of SOD activity in mouse brain between control group [(17.32 +/- 6.23)U/gHb] and 50 mg/kg nano-alumina particles group [(17.89 +/- 1.82) U/gHb]. The SOD activity [(4.93 +/- 2.30)U/gHb] in 200 mg/kg nano-alumina particles group was significantly lower than that in control group (P < 0.05). The MDA levels in 3 nano-alumina particles groups were (0.76 +/- 0.13), (1.00 +/- 0.30) and (1.16 +/- 0.39)nmol/ml, respectively, which were significantly higher than that [( 0.24 +/- 0.09)nmol/ml] in control group (P < 0.05). The GSH levels in 3 nano-alumina particles groups were (0.72 +/- 0.08), (0.55 +/- 0.19) and (0.61 +/- 0.20)mg/gpro, respectively, which were significantly lower than that [(1.55 +/- 0.34)mg/gpro]] in control group (P < 0.05). The CAT activity in 50 and 100 mg/kg nano-alumina particles groups were (10.40 +/- 3.84) and (10.40 +/- 2.00)U/mgpro, respectively, which were significantly higher than that [(5.79 +/- 0.96) U/mgpro] in control group (P < 0.05). The CAT activity [(3.25 +/- 1.04)U/mgpro] in 200 mg/kg nano-alumina particles group was significantly lower than that in control group (P < 0.05 ).

CONCLUSIONNano-alumina particles can induce the oxidative stress damage in brain tissues of mice.

OBJECTIVETo study the clinical features and treatment outcome of children with mature B-cell non-Hodgkin's lymphoma (B-NHL).

METHODSA total of 28 previously untreated children with mature B-NHL were enrolled and given the chemotherapy regimen of CCCG-B-NHL-2010. Among them, 20 were given rituximab in addition to chemotherapy. The children were followed up for 31 months (ranged 4-70 months). A retrospective analysis was performed for the clinical features of these children. The Kaplan-Meier method was used for survival analysis. A univariate analysis was performed to investigate the prognostic factors.

RESULTSAmong the 28 children, 17 (61%) had Burkitt lymphoma, 8 (29%) had diffuse large B-cell lymphoma (DLBCL), and 3 (11%) had unclassifiable B-cell lymphoma. As for the initial symptom, 13 (46%) had cervical mass, 10 (36%) had maxillofacial mass, 9 (32%) had hepatosplenomegaly, 5 (18%) had abdominal mass, and 5 (18%) had exophthalmos. Of all children, 14 had a lactate dehydrogenase (LDH) level of <500 IU/L, 3 had a level of 500-1 000 IU/L, and 11 had a level of ≥ 1 000 IU/L. After two courses of chemotherapy, 21 children achieved complete remission and 7 achieved partial remission. At the end of follow-up, 24 achieved continuous complete remission and 4 experienced recurrence. The 2-year event-free survival rate was (85.7± 6.6)%. The children with bone marrow infiltration suggested by bone marrow biopsy, serum LDH ≥500 IU/L, and bone marrow tumor cells >25% had a low 2-year cumulative survival rate.

CONCLUSIONSThe CCCG-B-NHL 2010 chemotherapy regimen combined with rituximab has a satisfactory effect in the treatment of children with B-NHL. Bone marrow infiltration on bone marrow biopsy is associated with poor prognosis.

OBJECTIVETo evaluate the application value and feasibility of various cervical screening methods and to explore a rapid and efficient cervical cancer screening program for the women in the rural areas of China.

METHODSWe sequentially conducted human papillomavirus (HPV) DNA test by hybrid capture-2 (hc2) with cervical cells, liquid-based thinprep cytology test (TCT), visual inspection with acetic acid (VIA), visual inspection with iodine (VILI), colposcopy respectively for the 2499 married women between 30 and 49 years from Xiushui county of Jiangxi province. All the detection methods were performed independently under double-blind design. Women who were diagnosed positive for having any VIA,VILI and colposcopy inspection or for those women who were diagnosed negative for VIA, VILI and colposcopy but with positive result of HPV or TCT test underwent cervical biopsy directly and endocervical curettage (ECC)when necessary. We performed cervical biopsy endocervical curettage within two weeks to observe the sensitive (SE), specificity (SP), negative predict value (NPV) and positive predict value (PPV) of these detection methods when used alone or combined each other, including HPV test, TCT inspection, VIA, VILI, and colposcopy, the pathological diagnosises of cervical tissue were confirmed by IARC (International Agency for Research on Cancer) while the cytological findings were underegone through the updated program of TBS (The Bethesda System) in 2001.

RESULTSA total of 2499 women underwent the screening and found 443 women who were diagnosed as HPV positive, 337 women with abnormal cervical cytology and 27 women with ASC-H, 157 cases with ASCUS; 103 cases with HSIL, 49 cases with LSIL and 1 cervical cancer. According to the pathological findings. There were 181 women diagnosed as cervical intraepithelial neoplasia (CIN) or cervical cancer, including 81 cases with CIN1 37 cases with CIN2,60 case cervical cancer. The sensitivity rates of HPV, TCT, HPV+ TCT, VIA, VILI, VIA+VILI and colposcopy were 96.67%, 89.47%, 97.98%, 56.57%, 36.36%, 63.64% and 39.39%, and the specificity rates were 85.00%, 96.91%, 86.97%, 94.60%, 96.23%, 92.97% and 98.14% respectively.

CONCLUSIONHPV + TCT seemed to be more sensitive than other screening methods in the cervical cancer screening program.
