Abstract?AIM: To determine the relation between each of the optical coherence tomography ( OCT) patterns, etiologies and visual acuity in patients with cystoid macular edema ( CME) .?METHODS:Fifty-seven eyes with CME from 52 patients were included in our study. The data of this cross sectional study was collected rfom p atient s wtih CME assessed by OCT, who also underwent fun dus photography and visual acuity test the same day. The best corrected visual acuity ( BCVA ) was assessed by using E chart a nd converted in logarithm of the minimum angle of resolution( logMAR ) . Thevisual acuity varied from 2.3 logMAR to 0 logMAR w ith a mean of 1.11±0.57. The etiology was determined from medical history and the fundus ph otograph of the patient. Four O CT grades established according to ratio between the vertical size of largest cyst and the maximum macular thickness (<30 %,≥30% <60%,≥60% <90%and≥90%) were considered. The correlation was established by calculating the Pearson's correlatio n coefficient “r” and the statistical significance was considered when P value was inferior to 0.05.?RESULTS: OCT grade I V was the most associated with very severe visual loss with the greatest mean VA of 1.96± 0.23 logMAR and the correlation between OCT grades and visual acuity was strongly statistically significant ( r =0.729, P <0.001 ). The central retinal vein occlusion ( CRVO) was the most underlying disease associated with worsev ision, with the gre atest mean VA of 2 logMAR and the correlation was statistically significant ( r=0.375, P=0.004).Another associated OCT pattern, the disruption of bot h inner segment/outer segment ( IS/OS) and external limiting membrane ( ELM) , was inversely associated with severe visual loss ( high mean VA=1.11 ±0.57 logMAR, with statistically significant correlation, r=-0.346, P=0.008 ) . The presence of both vitreoretinal traction components and outer retinal layers disruption were significantly associated with OCT grade IV ( r=0.390, P=0.003) and CRVO (r=0.362, P=0.006).?CONCLUSION:In this study, the OCT fourth grade and CRVO seem to be more significantly associated with the worse vision in patients with CME.

Objective To evaluate the ability of multi-slice spiral CT angiography(MSCTA)in showing the celiac trunk and its degree branches,and the value of MSCTA in preoperative evaluation of laparoscopic-assisted gastrectomy for advanced gastric carcinoma.Methods A total of 25 consecutive patients scheduled for laparoscopic-assisted gastrectomy with D2 lymph node dissection were evaluated by MSCT,CT angiography(CTA)were reconstructed separately using a volume rendering algorithm(VR).The space anatomy characteristics of celiac artery and its degree branches were evaluated according to the CTA results,and with anatomy information,laparoscopic-assisted gastrectomy with D2 lymph node dissection was processed with references to anatomy.Results In all the 25 cases,the left gastric artery and gastroduodenal artery were accurately identified on MSCTA.In 12 of them,the right gastric artery was accurately identified.The origin of the spleen artery is relatively constant.Laparoscopic-assisted gastrectomy with D2 lymph node dissection was successfully completed without conversion to open surgery in all the cases.The reconstructed celiac trunk and branches are identical with anatomy.Conclusions Three-dimensional CTA using MSCT clearly reveals the anatomy of celiac artery and their space structure.It plays an important role in guiding lymph node dissection during laparoscopic-assisted gastrectomy for advanced gastric carcinoma.

BACKGROUND: Nowadays, it is reported that vessel structural abnormity is the main morphological basis of vertigo due to vertebrobasilar arterial insufficiency abroad, but the report of vascular structural abnormality in vertebrobasilar arterial insufficiency is rare at home.OBJECTIVE: To observe the manifestation and clinical significance of vessel structural abnormity tested by digital substraction angiography (DSA)in patients with vertigo induced by vertebrobasilar arterial insufficiency.DESIGN: Case analysis.SETTING: Department of Neurology, Wuxi Second Hospital (Wuxi Municipal Second People's Hospital) Affiliated to Nanjing Medical University and Department of Neurology, Huaihua Hospital Affiliated to Nanhua University.PARTICIPANTS: A total of 57 patients, who were diagnosed as having episodic vertigo with or without nausea or vomiting, and hospitalized in the Department of Neurology, Huaihua Hospital Affiliated to Nanhua University from August 2003 to May 2004 and Wuxi Second Hospital (Wuxi Municipal Second People's Hospital) Affiliated to Nanjing Medical University between October 2004 and May 2005, were enrolled.METHODS: Fifty-seven patients with vertigo induced by vertebrobasilar arterial insufficiency hospitalized in the recent two years were treated with digital subtraction radiography in aortic arch and aortocranial angiography:Applying retrograde angiography of femoral artery puncture, Optiray nonionic contrast agent with syringe pattern to perform aortic arch angiography. Digital subtraction machine displayed bilateral carotid artery, vertebral artery, ranged from carotid artery to siphon of carotid artery from multiple angles. Measurement and evaluation were conducted by 2 doctors from department of neurology.MAIN OUTCOME MEASURES: Type, distribution and proportion of vesselstructural abnormity of aortic arch, carotid artery and vertebrobasilar system.RESULTS: Of the 57 patients, 1 patient was dropped out, because the left vertebral artery (LVA) could not be entered. A large area cerebral infarction was occurred in another patients during aortic arch angiography was performed, and the operation was stopped. Totally 55 patients were involved in the result analysis. It was found that 71%(39/55) of patients had vessel structural abnormity in cervical part and intracalvarium, 11%(6/55)of patients with simple anterior circulation lesion, 60% (33/55) of patients with posterior circulation lesion, of which 9 cases (16%) with compound lesion of anterior circulation abnormity. Two or above vessels in 24 cases (24/55,44%) were involved. Vertebral artery complicated with other angiostegnosis was the most common, and there was no vessel structural abnormity in other 16 cases (16/55,29%).CONCLUSION: Various types of vessel structural abnormity are the main etiological factors of vertigo induced by vertebrobasilar arterial insufficiency. Gold standard of diagnosing vertigo due to vertebrobasilar arterial insufficiency is DSA.

Objective To investigate the action mechanism of blood-stage treatment that affects psoriasis vulgaris using observation of the Th17/Treg expression.Methods A total of 32 patients ( blood heat group,n =17 ; blood stasis group,n =15) and 15 healthy people ( control group,n =15 ) were observed.The frequencies of Th17 and Treg in peripheral blood were detected by flow cytometric analysis in patients before and after treated by heat-clearing and blood-cooling decoction,qi-enriching and blood-activating decoction.Results The ratio of Th17/Treg in peripheral blood [ blood heat group (4.21 ± 0.52 )％ ;blood stasis group( 3.32 ± 0.43 )％ ] was significantly increased in patients compared with controls [ ( 1.79 ±0.18)％ ] ( P ＜0.01 ).After herbal treatment,the ratio of Th17/Treg expression in the blood heat group [ ( 2.41 ± 0.22 ) ％ ] and in blood stasis group [ ( 2.02 ± 0.12 ) ％ ] was significantly decreased ( P ＜ 0.05 ),respectively.Conclusions Blood-stage treatment works well on Th17/Treg expression in patients with psoriasis vulgaris.

The acute and chronic respiratory tract inflammation models were made to investigate the effect and mechanism of sterol extracts from Begonia Sinensis Rhizome (BSR). The first model of acute lung injury was made with Kunming mice by inhaling cigarette smoke, then the mice were treated with different concentrations of BSR sterol extracts. Lung tissue morphology was detected by HE staining, TNF-alpha/MPO were detected by Elisa, and cPLA2 protein were, detected by Western blotting respectively. Results showed that in model group, lung sheet became real, alveolar space shrank or disappeared, alveolar septum was thickened, plenty of inflammatory cells were infiltrated, capillary blood vessels were congestive and the expression of TNF-α, MPO, cPLA2 increased; after administration, a small amount of inflammatory cells were infiltrated, alveolar septum became obvious, capillary congestion status was significantly relieved and the expression of TNF-α, MPO, cPLA2 decreased (P < 0.05). The second model of chronic respiratory tract inflammation in BALB/c mice with bronchial asthma was induced by OVA, then the mice were treated with different concentrations of BSR sterol extracts. Lung tissue morphology was detected by HE staining, indexes such as IL-4, IL-5, IL-13 were detected by Elisa, and the cPLA2 protein expression was detected by Western blotting respectively. Results showed that in model group, a lot of inflammatory cells around lung vessels and bronchi exuded, bronchial goblet cells proliferated and the expression of IL-4, IL-5, IL-13, cPLA2 increased; after administration, inflammatory and goblet cell hyperplasia reduced, the expression of IL-4, IL-5, IL-13, cPLA2 also decreased (P < 0.05). The above results showed BSR sterol extracts could resist against respiratory inflammation by inhibiting cPLA2 in a dose-dependent manner.

Objective To study the changes of umbilical blood lactate,pH, blood sugar(BS),bilirubin, electrolyte, osmotic pressure (OP) in the newboms with fetal distress.Methods Thirty-five newborns with fetal distress (distress group) and 40 healthy new-borns (control group) were studied. Distress group were divided into distress group Ⅰ and distress group Ⅱ respectively, based on without or with neonatal asphyxia. Concentration of umbilical blood lactate was determined with enzyme method, pH, BS,serum total bilirubin (BIL), serum electrolyte (Na+ ,K+ ,Ca2+ ) and OP were analyzed respectively. Results 1. The difference of incidence of newborn asphyxia between distress groups (29.03%) and control group (2.50%) was statistically significant. 2. Compared with the controls and distress group Ⅰ, the umbilical blood lactate concentration significantly increased in distress group Ⅱ (P 0.05).The incidence of hyperglycemia was significantly elevated in distress groups than that in the control group. 4. Lactate concentration in distress I and distress fl group showed negative correlation with pH. Conclusion The concentration of umbilical blood lactate can provide the proof for diagnosis and prognosis of fetal distress.
