AIM: To evaluate the relationship between axial length ( AL ) , corneal and lens refractive power, and the refractive error in children.
METHODS:Totally 44 children 88 eyes with refractive error who underwent retinoscopy with cycloplegia, to be measured spherical equivalent refractive error. Axial length was measured by a noncontact optical biometry ( ZEISS IOL-Master) , and corneal K and anterior chamber depth ( ACD) were also measured by the same machine. The refractive power of the lens was calculated by using the SRK formula. The patients were divided into 3 groups, myopia (SE<0), hyperopia (SE>+0. 50D) and emmetropia ( 0 to + 0. 50D ). Linear Correlation and Regression were used to evaluate the correlation among the optical parameters.
RESULTS:Totally 44 subjects, 88 eyes, average 9. 04±2.39 years, spherical equivalent (SE) -3. 50D to +8. 75D. Hyperopic AL was shorter than the other two groups ( P<0.05), same trend in lens power. No significant differences among the 3 groups in corneal K and ACD. There was a negative correlation between age and SE, SE and AL, SE and lens refractive power, and there was a positive correlation between age and AL, age and lens power.
CONCLUSION:As the children's growing up, SE trends to myopia, and AL becomes longer, and lens power is stronger.

Objective To observe the effect of stellate ganglion block on patients with cerebral infarction.Methods36 patients with cerebral infarction were randomly divided into the control group and research group.Both two groups were treated with traditional treatment.The research group was added with stellate ganglion block.ResultsAfter 20 days treatment,the Neuro-function Deficit(NFD) scores of both two groups were significantly lower than that before treatment(P<0.01);but the NFD scores of the research group were significantly lower than that of the control group(P<0.01).The scores of Fugl-Meyer Assessment(FMA) and Barthel Index(BI) of both two groups were significantly higher after treatment(P<0.01);but the scores of FMA and BI of the research group were significantly higher than that of the control group(P<0.01).ConclusionStellate ganglion block can improve the nerve function of patients with cerebral infarction.

Objective To study the effect of intestinal trefoil factor(ITF) on nuclear factor-?B(NF-?B) in neonatal rats intestinal tissues with necrotizing enterocolitis(NEC),and to discuss whether ITF had protective function in NEC,and its role in the mechanism of NEC.Methods Fifty neonatal rats were randomly divided into 5 groups:group A as control group,group B as control plus ITF 0.2 mg group,group C as NEC group,group D as NEC plus normal saline(NS),group E as NEC plus ITF 0.2 mg.NEC models of neonatal rats were established.On the 4th day,all subjects were put to death.The intestinal tissue located at the boundary of ileum and cecum were obtained to observe histological changes and NF-?B level.Results The density of NF-?B(p65) increased significantly in group C and D compared with those in group A,B and E(Pa

Objective:To summarize our experience in perioperative anesthetic management for fulminant hepatic failure (FHF)patients receiving liver transplantation.Methods:The clinical anesthetic data of 48 FHF patients receiving orthotopic liver transplantations(OLT)from January 2006 to January 2007 were retrospectively analyzed,and the anesthetic management expe- rience was summarized.General anesthesia was applied;the hemodynamics was monitored during the operation and doses of adrenaline and phenylephrine were adjusted according to the monitoring results.Blood samples were obtained before operation, before anheptic,30 min after anhepatic phase,5 min before neohepatic phase,and 5 min,30 min and 60 min after neohepatic phase for blood gas and electrolyte analysis and for determination of coagulation function;the drugs were subsequently adjusted according to analysis results.Results:All the 48 patient underwent successful anesthetic management and there was no death dur- ing opearation.The average blood loss during operation was(5 219?478)ml.Mild alkalosis,hypokalemia,hyponatrium,and hy- pocalcemia were present before operations,pH,BE and HCO_3~- were obviously reduced 30 min after anhepatic phase and in- creased 60 min after neohepatic phase.Kalemia was obviously increased 30 min following anhepatic phase and began to increase 60 min following neohepatic phase.Calium concentration was decreased at the end of preanhepatic phase(P

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.

METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.

RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.

CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.

The systematic position of Fritillaria hupehensis has been in dispute. Phylogentic analyses were conducted on sequences of ITS, rpl16, matK sequences for species of F. hupehensis and allies. Lilium davidii was designed as outgroup. The analyses were performed using MP and ML methods. Conclusions could be achieved as follow. The topologies of MP and ML are consistent. The samples of F. hepehensis from different places form a supported clade with a strong bootstrap. And then form a strongly supported clade with F. anhuiensis, F. monantha. The results suggests that although F. hupehensis has a closet relation with the two ones, it exists some difference.

Investigation of simvastatin and its related substances was carried out using a reversed phase ultra performance liquid chromatography/tandem mass spectrometry method. The identification of impurities in simvastatin was performed with a triple-quadrupole mass spectrometer, with an electrospray ionization (ESI) source in the negative/positive ion mode. A total of 12 compounds were characterized in commercial samples, among which 2 impurities had never been reported. All the impurities were deduced based on the MS fragment pathways of simvastatin and the biosynthetic pathway of lovastatin. This work provides very useful information for quality control of simvastatin.

?AIM: To study the association of the single nucleotide polymorphism ( SNP) rs1157699 in the calcitonin receptor-like receptor ( CRLR ) gene with primary angle closure ( PAC) in a Han Chinese population.?METHODS: All samples, involved 232 PAC cases and 306 controls, were obtained from an epidemiologic survey conducted in Funing, Jiangsu Province, China. Genotyping were carried out by TaqMan-MGB probe using the real time quantitative polymerase chain reaction system to study the relationship between SNP of rs1157699 in CRLR gene and PAC.?RESULTS: The prevalence of CRLRrs1157699 genotype was 67.4%, 30.0%, 2.6% for CC, CT, TT in cases, and 71.3%, 27.0%, 1.7% in controls respectively.There was no difference between the two groups in the distribution of genotype and allele frequencies of rs1157699 (P>0.05).?CONCLUSION:Our results do not support a significant role for rs1157699 in CRLR with PAC.

At present, the English translation of TCM terms of pulse picture are various, which would bring confusion to the study and research on TCM diagnostics. In this paper, four principles for the translation are suggested by the authors: to distinguish the nomenclature of term with its connotative explanation, to translate with commonly used words in general, to create new word with common affix and to differentiate the terms similar in meaning. The authors tried to make choice the best translation for each kind pulse picture, and explained the reasons for selection.
