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.

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.

This research uses six Agrobacterium rhizogenes R1601, R15384, R1000, A4, R1025 and R1 to infect silymarin explants to induce hairy roots and silibin. All of the six A. rhizogenes can induce Silybum marianum to generate hairy roots and the A. rhizogene A4 shows comparatively high infection on the plant. This research determines the condition to induce silymarin hairy roots by the factors of infection time, pre-culturing, co-culturing and pH value. The fact that MS liquid medium fits the proliferation of silymarin hairy roots is determined. Through PCR molecular identification, it can be seen that the DNA plasmids in the A. rhizogenes are successfully integrated into the genome of transformed roots. Using liquid chromatography, it is determined that the silibin content in silymarin hairy roots is 2.5 times that in the plant In this research, the silymarin hairy roots culturing system is established, which lays a foundation for the study of culturing silymarin hairy roots and producing silibin.

Objective To compare the dose distribution of reserved planned tangential beam IMRT(2-field IMRT) with multifields beams IMRT(6-field IMRT) of the bulk-recurrent chest wall in postmastectomy breast cancer patients.Methods For 8 patients with chest wall in postmastectomy breast cancer bulk-recurrence,2-field IMRT and 6-field IMRT plans were generated on PTV in Pinnacle Planning System.The prescribed dose of PTV was 50 Gy in 25 fractions and GTV was 66-70 Gy which irradiated incrementally by subsequent plan in 8-10 fractions.The conformal index (CI) and homogeneity index (HI) of 95％ of prescribed dose over PTV were compared,while the dose distribution on ipsilateral lung and heart were evaluated.Results The CI of PTV by 6-field IMRT (0.66 ± 0.08) was higher than that of the2-field IMRT (0.53±0.10)(t=7.99,P＜0.05).The HI ofPTV by6-field IMRT (1.36±0.08)waslower than that of 2-field IMRT (2.19 ±0.78) (t =9.04,P ＜0.05).There was no statistical difference in V5,V10,V20 and V35 for ipsilateral lung and in D V35 and D for heart between two plans.Conclusions Compared with 2-field IMRT,6-field IMRT might have a better dose distribution on planning target volume(PTV) for chest wall in postmastectomy breast cancer bulk-recurrence patients,butthere is no significant difference in dose-volume of ipsilateral lung and heart between two plans.

Hepatic artery stricture (HAS) after liver transplantation can lead directly to transplanted liver function exhaustion and complications of biliary system. The early diagnosis and treatment are crucial for better prognosis. Doppler ultrasound is the first method of choice, and angiography can give further clear dignosis. The balloon dilatation is still effective for hepatic arterial stenosis. With the more adaptable usage of oronary stent, if possible, would reveal more promising result especially for tortuous stenotic hepatic artery. The vascular reconstruction or repeated liver transplantation is still the effective therapeutic methods.

Purpose:To study the expression of CD44v6 protein in breast carcinoma and its prognostic significance. Methods:100 cases of formalin-fixed paraffin-embeded female breast invasive ductal carcinoma tissues were retrospectively analyzed using EnVision~(TM) immunohistochemical method with the monoclonal antibody CD44v6.Statistical analysis was based on the Log-rank test and Cox analysis.Results:Sixty-six of 100 cancer tissues expressed CD44v6.Positive staining was mainly on the cell membranes.There was significant correlation between CD44v6 immunoreactivity and lymph node me- tastasis and TNM stage.The 5-and 10-year survival rates were 82.76% and 78.37% of patients with CD44v6 low-expres- sion tumors,and 64.1% and 49.88% of those with CD44v6 high-expression tumors,respectively;the difference between the two groups of patients was significant(P

Five patients was cured, two children was died, and two children was implanted the permanent cardiac pacemaker. During pacing, two patients had the electrode shifted,and one patient had the cardiac murmur,and one patient had the local skin infected.Conclusion Temporary cardiac pacemaker can successfully treat children with ASS attack;the earlier the implantation,the better the prognosis.

ObjectiveTo investigate the effects of medical chitin degraded membrane on post-surgical abdominal adhesions.MethodsForty adult rabbits were made to form abdominal adhesions and divided randomly into four groups including group A1 and its control group A2, group B1 and its control groups B2 with 10 animals in each group. Medical chitin degraded membrane was applied in the group A and group B to the surfaces of the positions where would be adhered. All animals were cut the belly open again on the 7th, 14th postoperative day; the adhesions about incision and appendix were graded according to the severity, and took on bioscopy.ResultsThe abdominal adhesions model was successful. The severity of adhesions and inflammatory reaction of the group A1 and group B1 was significantly milder than that of the group A2 and group B2 in every different periods ( P<0.05).ConclusionThe medical chitin degraded membrane used intraoperatively might have some efficacy in preventing post-surgical abdominal adhesions.

OBJECTIVETo explore effective approaches of treating elderly patients with distal tibiofibular fractures.

METHODSFrom August 2008 to October 2012,175 elderly patients with distal tibiofibular fractures were treated with locking compression plate (LCP) through anterior tibial. There were 112 males and 63 females with an average of 71.3 (ranged 60 to 83) years old. Of them,89 cases were treated by anterior tibial tension reduced incision with LCP,including 62 males and 27 females with a mean age of (71.8 +/- 6.4) years old. Eighty-six patients were treated by distal tibial incision with LCP,including 58 males and 28 females with a mean age of (70.3 +/- 6.7) years old. Swelling time, operation time, intraoperative blood loss, hospital stay, healing time, complications and AOFAS scores were compared between two groups after operation.

RESULTSSwelling time in anterior tension reduced incision with LCP and distal tibial incision with LCP was (5.6 +/- 1.3) and (9.7 +/- 2.1) days, healing time was (4.2 +/- 1.4) and (5.4 +/- 1.9) months,and complications were found 3 in tension reduced incision and 10 in distak tibial incision respectively;and all data shown statistically significant differences between two groups (P < 0.05). At 12 months after operation,AOFAS score was 89.0 +/- 9.7, 87.9 +/- 9.4; and there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONTension reduced incision through anterior tibial combined with locking compression plate fixation in treating elderly patients with distal tibiofibular fractures can provide good clinical effects with quick fracture healing and low complications.

Astragalus, which was first documented in Shennong Bencao Jing, is the dried root of Astragalus membranaceus (Fisch.) Bge. or Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao. The active ingredients astragalus membranaceus saponins (AMS), astragalus polysaccharides (APS) and astragalus flavonoids (AFS) have pharmacological effects such as anti-tumor properties, lowering blood sugar, regulating lipid metabolism, cardiovascular protection, anti-oxidation, bone protection, anti-fibrosis, etc. Fibrosis affects almost all organs, particularly vital organs such as the lungs, liver, heart and kidneys. The primary pathological changes of fibrosis involve abnormal increase of myofibroblasts and excessive deposition of extracellular matrix (ECM) components, which lead to the formation of scar tissue, ultimately resulting in fibrosis and even functional loss or failure of organs, which seriously threatens human health and life. Recent, studies have shown that Astragalus membranaceus has a good therapetuic effect on organ fibrosis. This article reviews the current advances of Astragalus in the prevention and treatment of fibrosis of lungs, liver, heart, kidneys and other important organs.
