To observe the curative effect of treating small -incision cataract extraction by intraocular lens implantation combined with trabeculectomy for primary angle-closure glaucoma with cataract.
●METHODS: Totally 44 cases (52 eyes) of primary angle-closure glaucoma combined with cataract were selected to undergo the combined surgery, in order to observe the patients' pre - and postoperative eyesights, intraocular pressures and the postoperative complications.
●RESULTS: The postoperative eyesight was improved significantly as compared with the preoperative eyesight. The intraocular pressure was declined dramatically. The result was of statistical significance (P<0. 05). All the 52 cases' surgeries were performed by the same surgeon. The surgeries were processed smoothly, with 6 postoperative eyes of anterior chamber inflammation cell response, 3 eyes of anterior chamber fibrinoid exudate, 2 eyes of shallow anterior chamber through mydriasis and treatment with glucocorticoids and non - steroidal eyedrops before absorption, and no complications like malignant glaucoma, cyclodialysis, etc. were reported through mydriasis and pressure bandaging before recovery.
● CONCLUSlON: Treating the primary angle - closure glaucoma combined with cataract through the combined surgery has high reliability and desirable curative effect. The surgical method is simple to learn and applicable for promotion on the basic level.

Objective To explore the quadriceps muscles function in patients with unilateral knee injury.Methods 23 unilateral knee injured patients with joint dysfuntion were assessed with isometric EMG activity of vastus lateralis (VL), vastus medialis obliques (VMO) and rectus femoris(RF) of both thighs during three 5-s maximal isometric voluntary contractions at a knee joint angle of 30° (0° - full knee extension), and the torque were recorded at same time. Results The average amplitude (AEMG), mean power frequency (MPF), and median frequency (MF) of VL, VMO and RF in affected knees were significantly lower than those in unaffected knees（P＜0.01）, as well as the torque（P＜0.01）. In the unaffected side, the AEMG, MPF of VL were higher than VMO and RF（P＜0.05）, and RF than VMO（P＜0.05）. In the affected side, the AEMG, MPF of RF are higher than VMO and VL（P＜0.05）, and VL than VMO（P＜0.05）. Conclusion sEMG can provide quantitative measurements of muscle function. The isometric strength and neuromuscular activation lever are lower in affected limb, RF may be affected less than VL and VMO in knee injured patients with knee dysfunction.

ObjectiveTo investigate the application of surface electromyography (sEMG) in patients with lumbar disc herniation. Methods44 patients with chronic lumbar disc herniation were divided into mild pain group (group A) and moderate to severe pain group (group B) according to their scores of Visual Analogue Scale (VAS). Their sEMG at erector spinae and gastrocnemius were collected, and the average EMG (AEMG), slope of median frequency (MFs) were analyzed. ResultsCompared with those in the healthy side, AEMG of erector spinae and gastrocnemius reduced significantly (P<0.05) in affected side in both groups, while the MFs (absolute value) increased (P<0.05). Compared with those in group A, the MFs (absolute value) in affected side significantly increased in group B (P<0.05). The ratio of healthy/affected side of AEMG increased in group B (P<0.05), but the ratio of MFs was no significantly difference between 2 groups (P>0.05). ConclusionSurface EMG, of both the erector spinae and gastrocnemius, can be used as a non-invasive tool in detecting neuromuscular function of lumbar and lower limb in patients with lumbar disc herniation. The sEMG imbalance may respond with the severity of pain.

Objective To investigate the phenotype, frequency and function of CD4 + T cell subsets and the relevant cytokines, as well as the relationship between these cells and appearance of pneumonia of novel (H1N1 ) influenza A patients. Methods 68 healthy people,53 confirmed novel A( H1N1 ) influenza patients without pneumonia and 16 confirmed severe novel A( H1N1 ) influenza patients with pneumonia were enrolled in this study. Viral load in nasopharyngeal swabs specimens was measured by real time PCR assay.The phenotype and percentage of CD4+ T cell subsets including Th1, Th2, Th17, and Treg cells were measured by Flow cytometry analysis. The relevant cytokines in plasma including TGF-β, IL-6 and IFN-γ were measured by ELISA. Data was analyzed by one way ANOVA. Results It was found that peak viral load and viral shedding period of severe patients with pneumonia was significantly increased compared with mild patients without pneumonia ( P ＜ 0. 05 ). The percentage of Th17 cells of severe patients with pneumonia was significantly diminished compared to that of healthy subjects and mild patients without pneumonia( P ＜ 0. 05 ). However, Th1 ,Th2, Treg cells frequencies had no significant differences ( P ＞ 0. 05 )among these three groups. The level of TGF-β in plasma for the severe patients with pneumonia was also significantly decreased compared to that of healthy subject and mild patients without pneumonia( P ＜0. 05 ).The viral shedding period inversely correlated with the frequency of Th17 cells ( r = - 0. 38, P ＜ 0.05 ).Conclusion H1N1 influenza A virus can inhibit Th17 cells to differentiate, particularly more extent in patients with pneumonia. Impaired Th17 cells may correlate with viral clearance and pneumonia of novel H1N1 influenza A patients.

The present study investigated the relationship between DNA-dependent protein kinase (DNA-PK) and radiosensitivity of nasopharyngeal carcinoma (NPC) cell lines. The dose-survival relationship for NPC cell lines, CNE1 and CNE2, was analyzed using clonogenic formation assay, the activity of DNA-PK of the two cell lines was measured using the Signa TECT DNA-PK assay kit, and the localization and expression of Kus (a heterodimer) and DNA-PKcs protein in CNE1 and CNE2 before irradiation and 15 min, 1 h, 6 h, 12 h, 24 h after 4 Gy irradiation were analyzed by immunofluorescence, laser scanning confocal microscope (LSCM) and Western blot. The results showed that the surviving fraction of CNE1 was higher than that of CNE2 at each dose. The DNA-PK activity of CNE1 was also significantly higher than that of CNE2 before and after irradiation (P<0.05), while the expression of total Ku70/Ku80 in CNE1 and CNE2 had no significant difference. Increasing translocation of Ku70 and Ku80 from the cytoplasm to the nuclei in the two cell lines was observed with increase of irradiation time as detected by Western blot, and the immunofluorescence of the DNA-PK complex subunits showed greater nuclear translocation in CNE1 than CNE2 after irradiation. The results suggest that the relatively higher radio-resistance of CNE1 correlates with the higher activity of DNA-PK as compared to that of more radiosensitive CNE2 (or lower radio-resistance) before and after irradiation. Thus, DNA-PK activity may be a useful predictor of radiosensitivity of NPC.

OBJECTIVE To observe the cross section diameter and the effects of pricking blood therapy on acute gouty ar-thrits rats model's interleukin-1β(IL-1β),interleukin-10(IL-10)mRNA expression and promoter methylation in local ankle,and explore the epigenetics mechanisms of pricking blood therapy's treatment.METHODS 36 SD rats were randomly divided into normal control group,urate arthritis group,ibuprofen group and bloodletting group.The acute gouty arthrits model set up by injecting uric acid into the right ankle joint cavity.The ibuprofen group was treated by gastric perfusion of ibuprofen,while the bloodletting group was pricked at the right Kunlun points.The swelling index of the modeling joint was evaluated,and the morphological changes were observed under light microscope.The mRNA expression levels and promoter methylation status of IL-1βand IL-10 in rats local ankle were detected by qPCR and pyrosequencing detection.RESULTS Compared with the urate arthritis group and ibuprofen group,the joint swelling index in the bloodletting group was decreased(P<0.01)after the treatment.Pricking blood therapy reduced intracellular deposition of uric acid in the joint cavity,and inhibited inflammato-ry cells to improve the synovial membrane tissue.Compared with urate arthritis group,the IL-1βmRNA expression levels of blood group was decreased significantly(P<0.01).IL-1βpromoter methylation and mRNA expression didn't showed a nega-tive correlation.Compared with normal control group,urate arthritis group and ibuprofen group,the expression levels of IL-10 mRNA in blood group increased significantly(P<0.01),and the average methylation rate of IL-10 among blood group de-creased significantly(P<0.05～0.01).IL-10 promoter methylation and mRNA expression showed a strong negative correla-tion(r=-0.899,P<0.01).CONCLUSION In epigenetics,the methylation of IL-10 can regulate the gene expression,which can be one of important mechanisms which shows anti-inflammatory effects of pricking blood therapy,.

Serum enzymes that play potential roles in tumor growth have recently been reported to have prognostic relevance in a diverse array of tumors. However, prognosis-related serum enzymes are rarely reported for nasopharyngeal carcinoma(NPC). To clarify whether the level of serum enzymes is linked to the prognosis of NPC, we reviewed the pretreatment data of lactate dehydrogenase(LDH), alkaline phosphatase (ALP), and glutamyl transferase (GGT) in 533 newly diagnosed NPC patients who underwent radical radiotherapy between May 2002 and October 2003 at Sun Yat-sen University Cancer Center. Patients were grouped according to the upper limit of normal values of LDH, ALP, and GGT. The Kaplan-Meier method and log-rank test were used for selecting prognostic factors from clinical characteristics and serum enzymes, and the chi-square test was applied to analyze the relationships of clinical characteristics and serum enzymes. Finally, a Cox proportional hazards model was used to identify the independent prognostic factors. We found that increased levels of LDH had poor effects on both overall survival and distant metastasis-free survival (P = 0.009 and 0.035, respectively), and increased pretreatment level of serum ALP had poor effects on both overall survival and local recurrence-free survival (P = 0.037 and 0.039, respectively). In multivariate analysis, increased LDH level was identified as an independent prognostic factor for overall survival. Therefore, we conclude that increased pretreatment serum LDH and ALP levels are poor prognostic factors for NPC.

The undifferentiated form of nasopharyngeal carcinoma (NPC) is the most common malignant head and neck cancer in South China, especially in Cantonese populations. However, few NPC cell lines have been established from the patients in this region. In this study, we established a new NPC cell line, termed SUNE2, from a Cantonese patient with undifferentiated NPC. This cell line had extremely low concentrations of Epstein-Barr virus (EBV) DNA in long-term culture and expressed low levels of latent membrane protein 1 (LMP1), latent membrane protein 2A (LMP2A), BamH1-A right frame 1 (BARF1), EBV-encoded RNA-1 (EBER1), and EBV-encoded RNA-2 (EBER2) in early passages. SUNE2 cells also showed much stronger transforming ability than 5-8F cells in colony formation assays and anchorage-independent growth assays in soft agar, and they only need 2 weeks to form tumors in nude mice. In summary, the SUNE2 cell line is a new in vitro model that can be used for further research on the mechanisms underlying the occurrence and development of NPC.
