Background Vitreous hemorrhage in long-term produces toxic substances and influent the metabolism of eye tissue.Lens capsule is found more thin and transparent in the eyes with chronic vitreous hemorrhage.To research the effect of vitreous hemorrhage to lens is very important for the choose of the phaco operative timing.Objective The aim of this work was to investigate the ultrastructural change of lens epithelial cells(LECs) in the eyes with experimental vitreous hemorrhage.Methods The autologous blood of 0.1 ml was intravitreally injected in the left eyes of 8 general New Zealand white rabbits,and the equal amount of phosphate buffered saline(pH7.4) was used at the same way in the right eyes.Vitreous and fundus were examined with direct ophthalmoscope on 1,3,5,9,15,20,25,30 days to assess the inflammatory response after intravitreal injection.The specimens of lens anterior capsule were obtained in 30 days after injection and the ultrastructure and apoptosis of LECs were evaluated under the transmission electron microscope. Results No obvious ocular inflammatory response was seen throughout the experimental duration,and there was no vitreous hemorrhage in the right eyes after intravitreal injection.The vitreous hemorrhage agglutinated with clear boundary in the left eyes on 1 day after intravitreal injection,and the hemorrhage turned into dark-red color on the fifth day.On the fifteenth day after injection,the hemorrhage mass became to be grey color and the vitreous liquefaction occurred in the left eyes.The hemorrhage disappeared until 25 days.But in the one month after injection of self-blood,the vitreous showed the deeper red color.The early apoptosis appeared in the LECs of the left eyes in the thirty day,presenting the enlargement and broaden of intercellular space,the decrease of mitochondria number,vacuolar change,expanse of endoplasmic reticulum and disappearance of the nuclear membrane structure. Conclusions Vitreous hemorrhage leads to the ultrastructural pathological changes of lens.

Objective To investigate the expression level and the significances of prognosis by miR-451a in nasopharyngeal carcinoma (NPC) in Guangxi. Methods The expressions of miR-451a in 89 cases of nasopharyngeal carcinoma were detected by real time RT-PCR. The relation among the expression level , the clinicopathologic features of NPC and its prognosis were analyzed. Results The expression of miR-451a were found in all of nasopharyngeal carcinoma. The expression level of miR-451a in nasopharyngeal carcinoma was negative correlated to overall survival and disease free survival (P = 0.01,P = 0.04). Conclusions miR-451a may play a key role in detection of nasopharyngeal carcinoma with poor prognosis.

OBJECTIVETo evaluate electroacupuncture on the efficacy and the safety of gastric and systemic functional recovery in patients with carbon dioxide pneumoperitoneum undergoing gynaecological laparoscopic surgery.

METHODSSixty patients undergoing gynaecological laparoscopic surgery were randomly divided into a regular anesthesia group (group A) and a combination electroacupuncture anesthesia group (group B), 30 cases in each group. The group A were treated with regular general anesthesia, and on the basis of general anesthesia, the group B were treated with electroacupuncture at bilateral Zusanli (ST 36) and Liangqiu (ST 34) by continuous wave and a frequency of 2 Hz 30 minutes before the surgery until the end of the operation. Sedation scale by Ramsay, nausea, vomiting and mental state scores of postoperative were evaluated and compared between the two groups.

RESULTSCompared with the group A, the sedation scale (1.19 +/- 0.56 vs 1.96 +/- 0.90), nausea score (0.59 +/- 0.80 vs 1.81 +/- 0.88), vomiting score (0.48 +/- 0.94 vs 1.89 +/- 0.93) and mental state score (0.96 +/- 0.73 vs 1.69 +/- 0.75) were all decreased significantly in the group B (all P < 0.01).

CONCLUSIONCombination electroacupuncture anesthesia can relieve postoperative irritable, nausea and vomiting, improve mental state after the operation and promote the gastric and systemic functional recovery. It is a good method for the adjustment of carbon dioxide pneumoperitoneum during laparoscopic surgery.

Background Following the accelerated speed of population aging in China,the incidence of cataract is rising gradually.Researches indicated that senescenee marker protein-30 ( SMP-30 ) is closely associated with the occurring and developing of cataract. Objective This study was to investigate the expression of SMP-30 in human lens epithelial cells(LECs) of age-related cataract and study the relationship between SMP-30 and apoptosis.Methods Capsulotomy was performed on 80 eyes of 59 patients with simple cortex age-related cataract and 70 eyes of 53 age-matched patients with nucleus age-related cataract.The anterior capsular specimens were obtained by circularly capsulorhexis during the operation.Expressions of the SMP-30 protein and mRNA in the LECs of two types of cataract were detected using immunochemistry and real-time PCR respectively.Apoptosis of the LECs was assayed by TUNEL.The differences of expression of SMP-30 and apoptosis were compared between the two types of cataract.Results Immunochemistry showed that SMP-30 was expressed in cytoplasm of LECs.The expression intensity of SMP-30 was higher in the center zone compared with periphery zone.The apoptosis rate of LECs was significantly higher in the center of the anterior capsule than the periphery in both two types of cataract ( nucleus cataract:19.34％±0.11％ vs 8.32 ％ ± 0.57 ％,P =0.025 ; cortex cataract:42.07 ％ ± 0.86 ％ vs 13.55 ％ ± 0.64 ％,P =0.010 ).The expression amount of SMP-30 mRNA was lower at the periphery than the center of lens in both two types of cataract (nucleus cataract:45.21±2.79 vs 76.42±11.21,P=0.042 ;cortex cataract:108.32±4.32 vs 206.34±15.67,P=0.037 ),and that of nucleus cataract was significantly lower than cortex cataract (60.02±9.08 vs 157.33 ± 13.01,P =0.034),and the apoptosis rate of LECs was declined in the nucleus cataract group compared with the cortex cataract group ( 14.05％ ±0.22％ vs 27.70％ ±0.81％,P =0.007 ). Conclusions LECs apoptosis exists in age-related cataract.SMP-30 probably plays an important role in the formation of cataract.

OBJECTIVETo study the clinicopathologic features of follicular dendritic cell sarcoma (FDCS) and its differential diagnosis.

METHODSTen cases of FDCS were studied by light microscopy, immunohistochemistry and in-situ hybridization. The clinical features and follow-up information were analyzed.

RESULTSAmongst the 10 cases of FDCS studied, the male-to-female ratio was 1:1. The mean age of the patients was 42 years. Six of them were located in cervical and peritoneal lymph nodes and four in extranodal sites (including tonsil, pelvic cavity, tail of pancreas and spleen). Histologically, the tumor cells had whorled, storiform or diffuse growth patterns. They were spindle in shape and contained syncytial eosinophilic cytoplasm, with round or oval nuclei, vesicular chromatin, distinct nucleoli and a variable number of mitotic figures. Multinucleated tumor giant cells and intranuclear pseudoinclusions were occasionally seen. There was a sprinkling of small lymphocytes and neutrophils within the tumor as well as in the perivascular region. Immunohistochemical study showed that the tumor cells were diffusely or focally positive for CD21, CD23, CD35 and D2-40, but negative for LCA, CD20, CD3, CD1a, HMB45 and CK. Some of them showed EMA, CD68 and S-100 reactivity. In-situ hybridization for Epstein-Barr virus-encoded RNA (EBER) showed positive signals in only one case (which was diagnosed as inflammatory pseudotumor-like FDCS). Of the 7 patients with follow-up information available (duration: 2 months to 39 months; mean: 14 months), 2 cases with paraneoplastic pemphigus died of pulmonary infection at 5 and 7 months respectively. The remaining 5 patients were alive and disease-free after surgical excision (+/- chemotherapy and radiotherapy).

CONCLUSIONSFDCS is a rare low to intermediate-grade malignant tumor. Appropriate application of FDC markers, such as CD21, CD35 and D2-40, would be helpful for arriving at a correct diagnosis. Most cases are associated with good prognosis after surgical treatment, with or without chemotherapy and radiotherapy. Patients with paraneoplastic pemphigus carry a less favorable prognosis.

OBJECTIVETo explore prognostic factors and the expression of glypican-3, hepatocyte antigen (HEP), alpha-fetoprotein (AFP), CD34 and CD10 in hepatocellular carcinoma (HCC) and their prognostic value.

METHODSClinicopathologic data were analyzed in 375 cases of HCC, in which 80 cases with follow-up were examined by immunohistochemical staining to detect the expression of glypican-3, HEP, AFP, CD34 and CD10 proteins. The relationship between the proteins expression and clinicopathologic features was also evaluated.

RESULTSTumor number (P = 0.000), tumor size (P = 0.025), tumor differentiation (P = 0.001) and vessel invasion (P = 0.000) were closely related to prognosis of HCC patients; the expression of glypican-3 (66/80,82.5%; P = 0.002), HEP (64/80,80.0%; P = 0.021), AFP (38/80,47.5%; P = 0.014) and CD10 (28/80,35.0%; P = 0.002) was significantly related to tumor differentiation; that of glypican-3 was significantly correlated with tumor number and presence of satellite nodules (P = 0.028) and that of AFP and CD10 was significantly correlated with portal vein thrombi (P = 0.000, P = 0.010). On Kaplan-Meier regression analysis, both low expression of HEP and high expression of AFP were closely related to poor prognosis.

CONCLUSIONSTumor number, size, differentiation and vessel invasion were important factors affecting the prognosis of patients with HCC. HEP and AFP have prognostic significance in HCC.

The study was aimed to investigate the action of Panax Notoginosides (PNS, extracted from notoginseng herb) on the expression of the apoptosis-related proteins (Daxx, Fas) and transcription factors (NFkB, c-Rel) in the hematopoietic cells and to explore the mechanisms of supporting cells to survive. The colony formation of CFU-GM and CFU-E in human bone marrow was assayed in the presence of various concentrations of PNS. The viability of cells was assayed by trypan blue and the changes of cell morphology were observed with microscope. The Annexin-V positive cells were detected by FCM. Three lineages of human myeloid HL-60, erythroid K562, megakaryoid CHRF-288 and Meg-01 cells were incubated in addition of PNS (10 mg/L) for 14 days. The nuclear or cytoplasm protein of cells was extracted and analyzed by Western blot with monoclonal antibodies against Daxx, Fas or NFkB, c-Rel. The results showed: (1) the proliferation on hematopoietic progenitor cells (CFU-GM and CFU-E) and four cell lines was promoted by PNS; (2) after the four cell lines were promoted by PNS and hungered through wiping off the sera, the viability of the four cell lines was high without significant morphological change and neither the detection of Annexin-V positive cells; (3) the expression of Daxx and Fas protein could be inhibited by PNS. Western Blot showed that Daxx in four cell lines treated by PNS were 33.3-61.5% lower than that in untreated controls. The Fas protein was also descended in three cell lines of K562, CHRF-288 and Meg-01 by 33.3-71.4% respectively, while Fas protein in HL-60 cells was no detectable difference after PNS treatment. (4) The transcription factors NFkB and c-Rel protein could be increased by PNS. The NFkB, c-Rel protein were also enhanced in three cell lines of K562, CHRF-288 and Meg-01 by (2.0-2.7) and (1.5-2.3)-fold respectively, while there were also no detectable difference in HL-60 cells after PNS treatment. It is concluded that PNS inhibites the expression of Daxx and Fas proteins, may decrease the apoptosis of the hematopoietic cells. The level of NFkB and c-Rel proteins can be enhanced by PNS, which not only stimulates the proliferation of cells, but also inhibits the activity of the waterfall of caspase and apoptosis of the hematopoietic cells. PNS may treat the disease with over-apoptosis of hematopoietic cells, as aplastic anemia.

The complete genome sequence of transmissible Gastroenteritis virus (TGEV) strain TS, previously isolated from Gansu province, was cloned and compared with published sequence data from other TGEV strains.Phylogenetic tree analysis based on the amino acid and nucleotide sequences of the S gene showed that the TGEV strains were divided into 3 clusters. TGEV TS showed a close evolutionary relationship to the American Miller cluster but had a 5' non-translated region (NTR) sequence closely related to the American Purdue cluster.Continued culture in different cell types indicated that TGEV TS virulence could be attenuated alter fifty passages in Porcine kidney (PK-15) cells, and that the Porcine kidney cell line IB-RS-2 (IBRS) was not suitable for culture of the TGEV strain TS.

To study the correct method for determining ABO blood types in infants and its influencing factors, blood types of 33 infants under 6 months old were determined by routine serological method, micro-column gel typing system and PCR-SSP genotyping method. Of the 33 cases with discrepant results of ABO blood type by different methods, the blood types of 32 cases were discrepant between red cell and serological typings in the routine serological method, and a false coincidence in 1 case was caused by bacterial infection resulting in B-like antigen. Correct blood typing was obtained in 27 cases with a correct rate of 84.4% (27/32) by using micro-column gel typing system. PCR-SSP method gave correct results in all of 33 cases. There was a significant difference between the results of micro-column gel typing system and PCR-SSP. It is concluded that to determine ABO blood type for infants < 6 months old, it is recommended to adopt micro-column gel typing system method, and what must be taken into account is the possible false coincidence caused by bacterial infection resulting in B-like antigen. In micro-column gel typing system, if the results of red cell and serological typing are identical, the principle is that blood transfusion must be performed with same ABO blood type between recipient and donor. If not, washed O red blood cells should be used for infants, and then change to transfusion with identical blood group according to PCR-SSP typing results.

OBJECTIVETo review the surgical treatment of supracardiac type of total anomalous pulmonary venous connection (TAPVC).

METHODSTwenty-four patients with supracardiac total anomalous pulmonary venous connection underwent surgical correction from July 1995 to June 2004. There were 11 males, 13 females. The patients aged from 40 days to 35 years (mean 4.5 years). Twenty-three patients were under 6 years old. The weight was from 3.8 to 54.0 kg (mean 17.5 kg). Ten patients were through right atrial incision, 8 through double-atrium incision to anastomose the left atria and the common pulmonary veins. Two used large patches separating the portal of the common pulmonary veins and the enlarged atrial septal defects to the left atria. The left atrium and the common pulmonary veins were anastomosed in one case using a large patch separating the portal of the common pulmonary vein and the enlarged atrial septal defect to the left atrium. Three anastomosed the top of the left atria and the common pulmonary veins.

RESULTSOne patient died postoperatively of low cardiac output syndrome. One with cardiac tamponade after operation was cured by reoperation. Six with arrhythia were all cured. One with acute pulmonary edema was cured by reopen of the vertical vein and closed later. The postoperative follow-up period ranged from 3 months to 7 years (mean 2.5 years). One complicated severe supracardiac arrhythia 2 weeks later. One with late pulmonary occlusion was cured by reoperation. There was no long term complication of the others.

CONCLUSIONSThe operative methods of TAPVC depend on the cardiac deformation. Proper surgery timely treatment of the postoperative complications may achieve a satisfactory result. The method of only use patch in the right atrium should select proper repair material. Anastomosing the top of the left atrium and the common pulmonary vein is a good method. It is easy for exposure and operating, meanwhile it has low occurrence of arrhythmias and should be recommended.
