BACKGROUND: Cervical sympathetic ganglia block accelerates the re covery of the homeostasis of organic nervous-endocrine-immune system, butit is still unclear whether it can suppress the imbalance of homeostasis in duced by post-traumatic stress disorder. OBJECTIVE: To observe the effect of cervical sympathetic ganglia blockon the mortality of mice with combined radiation and burn injury, andwhether it can become an easy and effective method to treat secondarydamage after serious trauma. DESIGN: A randomized grouping design, an animal controlled experiment. SETTING: Department of Anesthesiology, Guangzhou General Hospital, Guangzhou Military Area Command of Chinese PLA.MATERIALS: The experiments were carried out in the Institute of Combined Injury, the Third Military Medical University of Chinese PLA between February 2004 and July 2005. Totally 160 Kunming mice were randomly divided into control group (n=50) and cervical sympathetic ganglia block group (n=50). In the control group, the mice were only induced to models of combined radiation and bum injury, and treated with injection of 0.3 mL saline at cervical part. In the cervical sympathetic ganglia block group, the mice were induced to models of combined radiation and burn injury, and then treated with cervical sympathetic ganglia block, once a day for 14 days continuously.METHODS: Methods to induce injury in the animals: ① Radiation injury: The mice were given even radiation of 60Coγ ray (5 Gy) at a distance of 1.5 m to the whole body, the rate of absorptive dosage was (5.17-5.33) mGy/s. ② Burn injury: After the radiation injury, coagulated gasoline was smeared on the back and burnt for 8 s to induce degree Ⅲ burn injury of 15% of the total body surface, which was proved by the pathological section. Methods of cervical sympathetic ganglia block: Cervical sympathetic ganglia block was given bilaterally, and then the mice were injected with 0.2 mL lidocaine (5 g/L), and it was observed whether the symptoms similar to Horner syndrome (hyperemia of conjunctiva, drooping eyelid,blushing, smaller eyeslit) occurred or not at 5 minutes after injection.MAIN OUTCOME MEASURES: The mortality at 2, 5, 7, 10, 20 and30 days after injury and the changes of the numbers of red blood cells,white blood cells and blood platelet in peripheral blood at 7, 14 and 21 days after injury were observed in both groups. The effects of cervical sympathetic ganglia block on the levels of tumor necrosis factor-alpha (TNF-α),interleukin-1β (IL-1β) and interleukin-6 (IL-6) in serum at 3, 6 and 14days after combined radiation and burn injury were also observed.RESULTS: All the 160 mice were involved in the analysis of results without deletion. ① Compared with the control group, the mortalities at 5,7, 10, 15, 20 and 30 days in the cervical sympathetic ganglia block group were significantly decreased [control group: 8%, 22%, 32%, 54%, 74%,82%, 90%; cervical sympathetic ganglia block group: 8%, 14%, 16%, 22%,28%, 34%, 56%]. ② Compared with the control group, the numbers of red blood cells, white blood cells and blood platelets in peripheral blood at 7,14 and 21 days after injury in the cervical sympathetic ganglia block group were significantly increased [at 21 days: red blood cells: 23.21×1012 L-1, 14.58×1012 L-1; blood platelet: 16.87×1011 L-1, 12.57×1011 L-1; white blood cells: 20.65×109 L-1, 14.58×109 L-1]. ③ The levels of TNF-α, IL-1β andIL-6 in serum at 3, 6 and 14 days after injury in the cervical sympathetic ganglia block group were significantly decreased as compared with those in the control group [at 14 days: TNF-α: 189, 365 ng/L; IL-1β: 14, 23 ng/L;IL-6: 70, 132 ng/L].CONCLUSION: Cervical sympathetic ganglia block can significantly decrease the mortality of animals with combined radiation and burn injury,and it is an easy and effective method to treat serious trauma, and the mechanism may be realized through accelerating the recovery of hematopoietic function and suppressing the excessive inflammatory reaction.

· AlM:To analyze the association between the macular thickness and emmetropic, low myopic, moderate myopic and highly myopic eyes.
·METHODS:The 276 teenagers (276 eyes) between 18~28 years treated in our hospital from January, 2013 to May, 2014 were selected, whose corrective visual acuity was≥1.0 and intraocular preasure was ≤21mmHg and who were willing to participate in this research.Forty-nine emmetropic, 72 low myopic, 104 moderate myopic and 51 highly myopic eyes were measured by optical coherence tomography ( OCT ) to detect the central subfield thickness, bitamporal, superior, lateral and inferior region thickness of inner and outer region, average thickness of retinal macula, foveal thickness and retinal volume.The thickness of different parts of macula lutea was measured and statistically compared among emmetropic, low myopic, moderate myopic and highly myopic eyes.
· RESULTS: The central subfield thickness of emmetropic, low myopic, moderate myopic and highly myopic eyes were (225.38±20.97), (230.97±19.15), (227.01±16.92), (231.91 ±18.97 )μm. The average thickness of retinal macula, of emmetropic, low myopic, moderate myopic and highly myopic eyes were (280.92±12.71), (278.15± 11.90), (270.05±12.07), (267.93±11.08) μm.There were no significant differences of center thickness (F=1.253, P=0.291) and central subfield thickness ( F=1.034, P=0.378) between emmetropic, low myopic, moderate myopic and highly myopic eyes.The macular thickness of inner and outer region in moderate myopic eyes was significantly less than that in emmetropic eyes, and there was significant difference (P<0.05).Comparison between low myopic, moderate myopic and highly myopic eyes was carried out and macular thickness of all regions of inner and outer region in moderate myopic group was significantly increased, and there was significant difference (P<0.05).There was no significant difference when compared with the macular thickness of inner and outer region of the highly myopic group (P>0.05).
· CONCLUSlON: ln low myopic eyes of teenagers, the center macular thickness do not become thinner. However, the macular thickness of inner and outer region is thinner than that of emmetropic eyes.Furthermore, with the increase of the degree of the myopia, the amount of macular thinner gradually decreases from outer region to inner region.

Intrauterine growth retardation (IUGR) is one of the most commonly encountered developmental toxicity, which could lead to perinatal morbidity and mortality, be also extended from the fetus to adulthood, and seriously affect the quality of the population. Caffeine widely exists in a variety of daily beverages and some drugs. Its consumption is increasing year by year. Caffeine intake during pregnancy is one of the risk factors for IUGR. However, its mechanism of adverse outcome based on embryonic research is still unclear. In this paper, the possible mechanisms of caffeine-induced IUGR focusing on 3 important factors-the mother, placenta and fetus were explored. Caffeine's impact on the mother is the chronic activation of renin-angiotensin system; on the placenta, caffeine induces cell damage or the failure of the cell proliferation/apoptosis balance, leading to blockage of blood supply to the placenta; caffeine is also capable of directly affecting fetal development through interfering its neuroendocrine.

OBJECTIVETo observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia.

METHODSTotally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups.

RESULTSCompared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05).

CONCLUSIONTreatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.

Quercetin and its glycosides are important flavonols in traditional herbal drugs and plant-derived food, and they have diverse hiological activities such as antioxidant, anticarcinogenic, anti-inflammatory, hypoglycemic and hypolipidemic activities. Numerous studies have demonstrated that quercetin and its glycosides were effective in the prevention and treatment of non-infectious chronic disease such as diabetes, obesity, and hyperlipidemia. They can regulate glucose and lipid metaholism through different mechanisms. They can decrease blood glucose via protecting pancreatic/p cells or/and improving insulin sensitivity. Also, they have lipid-lowering effects, which may be the result of regulation of lipid catabolism or/and anabolism. Their distributions, as well as the hypoglycemic and hypolipidemic effects are reviewed in this paper. In addition, further bioactivities as well as their dose-activity relationship, structure-activity relationship, bioavailability, and future clinical application of quercetin and its glycosides are discussed and proposed.

INTRODUCTIONLong-term, high-dose corticosteroid therapy is well-known to cause systemic and ocular complications. A lesser known complication is chronic central serous chorioretinopathy (CSCR). Although idiopathic central serous chorioretinopathy (CSCR) is known to be mild with spontaneous recovery and minimal effects on the final visual acuity, chronic CSCR as a complication of long- term steroid therapy behaves differently, and may cause irreversible visual impairment.

CLINICAL PICTUREThree cases of chronic, recurrent CSCR were precipitated by longterm corticosteroids prescribed for post-renal transplant immunosuppressive therapy, postpituitary surgery and pemphigus vulgaris.

TREATMENT AND OUTCOMETwo cases resolved with tapering of corticosteroids while one case was treated by focal laser photocoagulation. Two eyes had severe impairment of vision as a result of subretinal scar formation while the other 4 eyes had mild reduction of visual acuity from retinal epithelium pigment atrophy.

CONCLUSIONLong-term corticosteroid therapy can be complicated by severe, chronic and recurrent CSCR and occasionally peripheral exudative retinal detachment. This may result in subretinal fibrosis and permanent loss of vision.
