SUMMARY To investigate the effect and feasibility of total laparoscopy to treat hepatolithiasis using gall-bladder-hepatic duct subcutaneous tunnel.Retrospective analysis was conducted of the case data of 11 pa-tients with hepatolithiasis who underwent total laparoscopic treatment using gallbladder-hepatic duct sub-cutaneous tunnel from January 2010 to October 2014.The operation time,blood loss,postoperative com-plications and recurrence of stones were recorded.All the cases completed the operation.The average hos-pital-stay was 9.2 days (range:3 -29 d).The average operation time was 298 min (range:225 -480 min).The average blood loss was 253 mL (range:50 -700 mL),and the average blood loss of liver re-section groups was 325 mL (range:200 -700 mL).The average discharge time was 3.3 days (range:3 -5 d).The rate of postoperative residual stones was 36.4% (4 /11).We extracted stones with chole-dochofiberscope via T-tube sinus six weeks after operation.One case developed biliary leakage,and healed through adequate drainage and the T-tube was pulled out after one month.There was no periopera-tive mortality.All the cases were followed up and the mean follow-up was 22 months (range:2 -51 months).The anastomotic stenosis of gallbladder-hepatic duct was found in one case.But we got a good therapeutic result with performed gallbladder chemical ablation with 95% ethanol.No recurrence of hepa-tolithiasis was found.As a choice for minimally invasive method to hepatolithiasis using gallbladder-he-patic duct subcutaneous tunnel,total laparoscopy is a safe and feasible procedure.

?AlM:To study the relationship between blood lead level and abnormal eye blinking in children.
? METHODS: The patients with chief complaint of frequent eye blinking, whose diagnosis of abnormal eye blinking, were randomized to experimental group. The patients in this group carried out vision and the slit-lamp examination, detected corneal fluorescein staining and tear break-up time, and improved the level of blood lead and trace elements examination. The patients in control group with chief complaint of health physical examination in our hospital, excepted of blood lead level, the other body check results were normal and were divided into boys group and girls group according to the gender. The changes of the experimental group and control group in blood lead level were compared.
?RESULTS: Totally 371 cases ( male:295 cases; female:76 cases) with mean age was 6. 56±2. 41 years and 6. 08±2. 82 years respectively were in experimental groupe. ln control group, there were 300 cases ( male: 186 cases;female:114 cases) with mean age was 6. 99±3. 01 years and 6. 56±2. 80 years respectively. The average of blood lead level of boys in experimental group was 63. 82 ±24. 56μg/L and 53. 98±15. 42μg/L in control group. The average of blood lead level in experimental group was higher than that in control group. The difference between of the two group was statistically significant (χ2=16. 96, P<0. 01 ). The average of blood lead level of girls in experimental group was 56. 96±16. 69μg/L and 48. 18±12. 35μg/L in control group. There was no difference between of the two group (χ2=5. 77, P=0. 56). ln control group, the average of blood lead level with <3 years, 3~6 years and >6 years children were 48. 73±11. 67μg/L, 51. 39 ± 14. 87μg/L, 52. 98 ± 14. 45μg/L respectively. ln expirement group, the results were 56. 57±17. 89μg/L, 59. 92±18. 46μg/L and 67. 00±32. 55μg/L in <3, 3~6 and >6 children, respectively. There was no significant difference with <3 years (χ2=3. 54, P=0. 17). The difference with 3~6 years and >6 years children were statistically significant (χ2 = 9. 62, P = 0. 008 ) and (χ2 = 19. 22, P = 0. 000 ) respectively. The blood lead level were divided into three grades: <50μg/L, 50 ~100μg/L, >100μg/L, and relative risk (RR) were 0. 65, 1. 22, and 10. 11 respectively.

A strain NK13 was screened for a certain extent asymmetric hydrolyze the rac-ketoprofen chloroethyl ester and identified as Bacillus megaterium. For the preparation of gene libraries, a positive clones was obtained from the tributyrin flat. The sequence of this esterase gene had been analysised, and contained the whole ORF of an esterase gene with the length of 933bp. The esterase gene of NK13 was compared with the esterase genes of GenBank and the result showed that the esterase gene of NK13 was a novel gene(GenBank accession nember DQ196347).The new esterase gene was inserted into the plasmid pET21b+, then the recombinant plasmid transformed E.coli BL21. After being induced by IPTG, it was expressed in the host strain. SDS-PAGE analysis showed that the relative molecular mass of the esterase was about 34kDa. The result of TLC and HPLC showed that the recombinant strain had higher conversion ration than templet strain. 47.4%of the rac-ketoprofen Chloroethl ester was hydrolyzed to ketoprofen by the recombinant strain in 45min. The (S)- ketoprofen enantiomeric excess, in the later,was 55.46%, which indicated that the esterase could hydrolyze (S)-ketoprofen chloroethyl ester firstly.

OBJECTIVETo explore the clinical roles of Jiawei Shentong Zhuyu Decoction (JSZD) in preventing the occurrence of failed back surgery syndrome (FBSS), and to observe its effect on serum tumor necrosis factor-alpha (TNF-alpha).

METHODSTotally 100 patients prepared for surgical operation due to lumbar intervertebral disc herniation were randomly assigned to the treatment group and the control group according to random number table, 50 cases in each group. Patients in the treatment group additionally took JSZD, one dose per day, taken in two portions, once in the morning and once in the evening. Those in the control group took Celecoxib Capsule (200 mg each time, once per day) and Mecobalamin Tablet (0.5 mg each time, 3 times per day). They only took Mecobalamin Tablet from the 11th day. All patients were treated for 30 days. Japanese Orthopaedic Association (JOA) score was performed before treatment, at week 1, after treatment, at 6 months of followed-ups, and at 12 months of followed-ups. And the levels of TNF-alpha in the peripheral blood were observed before treatment and at one month after treatment.

RESULTSTotally 93 patients completed the followed-up study. The JOA scores were improved after treatment, at 6 and 12 months of followed-ups (P < 0.05, P < 0.01). The JOA score at 6 months of followed-ups was superior in the treatment group to that of the control group (P < 0.05). Five patients (accounting for 10.6%) suffered from FBSS in the treatment group, while 9 (accounting for 19.6%) suffered from FBSS in the control group. The treatment group was superior to the control group (P < 0.05). The TNFalpha level was improved after treatment in the two groups. Of them, the improvement of TNF-alpha in the treatment group was better than that of the control group (P < 0.05).

CONCLUSIONThe application of JSZD was effective for preventing the occurrence of FBSS, and improved the serum TNF-alpha level.

OBJECTIVETo investigate the impact of preoperative radiochemotherapy on postoperative complications in patients with mid-low rectal carcinomas.

METHODSClinicopathologic data of T3 and T4 patients with mid-low rectal carcinomas in the Department of Colorectal Surgery at the Changhai Hospital of The Second Military Medical University from January 2009 to December 2010 were analyzed retrospectively. This cohort included 81 patients treated with preoperative radiochemotherapy followed by operation(radiochemotherapy group) and 93 cases who underwent surgery alone(control group).

RESULTSBoth resection rate and sphincter preservation rate were higher in the radiochemotherapy group(100% and 86.4%) than those in the control group(94.6% and 73.1%), and the difference in sphincter preservation rate was statistically significant(P=0.039). There were no significant differences in the mean operative time [(130±15) min vs.(125±20) min, P>0.05] and mean amount of bleeding [(100±15) ml vs. (95±10) ml, P>0.05] between the two groups. The overall incidence of postoperative complications was similar(9.9% vs. 9.7%, P>0.05).

CONCLUSIONSPreoperative radiochemotherapy can significantly increase sphincter preservation rate of mid-low rectal carcinomas, and does not increase the difficulty in surgical procedure and postoperative complications.

OBJECTIVE: To investigate the biological characteristics of endothelial progenitor cells (EPCs) from the umbilical cord blood (UCB), and to evaluate their oncogenicity after long-term culture in vitro. METHODS: The mononuclear cells (MNCs) were isolated from the UCB and cultured in MCDB131 medium supplemented with 20% FBS, VEGF and other growth factors. Morphology of the EPCs was observed, and the growth curve of the EPCs was investigated. Surface antigens of the EPCs were analyzed by the flow-cytometer. The capability of intaking the acetylated low-density lipoprotein (acLDL) of the EPCs was detected using fluoresencent chemical method. The vasoformative capability and genetic stability of EPCs were cultured in matrigel, and examined by karyotype analysis. The oncogenicity of EPCs was verified by the tumorigenesis test in athymic mouse and soft agar. RESULTS: EPCs were successfully derived from the UCB, and could be passaged to at least 42(nd) generation and had strong abilities of proliferation, acLDL intake and vasoformation, but there was not oncogenicity. They expressed endothelial cell-surface antigens and maintained normal karyotype. CONCLUSION The EPCs with proliferative potential can be isolated from the UCB. They can be passaged in long-term cultures without oncogenicity, and can maintain normal karyotype. The EPCs can be served as a new type of cells in cell and gene therapy.

OBJECTIVETo explore the indication law of fourteen channels acupoint that is located in the same nervous segment of T1-T12 on the back and abdomen.

METHODSBy retrieving indications of fourteen channels acupoint that is located in the dominating areas of T1 - T12 in LIN Zhao-geng 's New Collection of Acupuncture-moxibustion and SHEN Xue-yong's Science of meridian-collateral and acupoint, indications of fourteen channels acupoint in the same nervous segment of skin and muscle were statistically managed, respectively.

RESULTSThere was an obvious nervous segmental law of acupoint in the skin and muscle. The acupoint indication of neighboring nervous segment was similar, which was closely related to corresponding internal organs.

CONCLUSIONThe acupoint indication is decided by the space of nervous segment which dominats their related organ. From aspect of nervous structure, this article confirms that acupoint indications focus on nervous segment to carry out the regulation effect of acupoint on internal organs function, which means it has superior regulation effect on internal organs disease that is located in the same or neighboring nervous segment of acupoint.
