Chinese Journal of Endemiology 2008;27(4):401-404
Objective To construct and identify the transgenic plant vector recombinant pBI-Eg95 plasmid of Echinococcus granulosus. Methods Total RNA was extracted from hydatid cyst protoscoleces of Echinococcus granulosus after sonication. A couple of specific primers were designed on the basis of known sequences of Eg95 gene. The desired gene was amplified by PCR technique from the cDNA, and then was cloned into the plant expression vector pBI121 to construct the recombinant pBI-Eg95 plasmid. The recombinant plasmid was electroporated into Agrobocterium tumefaciens (At) LBA4404 strain. The positive recombinant clones were confirmed by restriction endonuclease digestion and characterized by PCR. Results For RT-PCR, a specific band around 471 bp was amplified. The result of DNA sequencing of Eg95 showed the identity with the published sequence. The same band was obtained by restriction endonuclease digestion and PER from the plasmids of positive recombinant At(rAt). Conclusions The recombinant pBI-Eg95 plasmid was successfully constructed, and it provides the basis to further research of the transgenic plant vaccine of Echinococcus granulosus.

Chinese Journal of Primary Medicine and Pharmacy 2009;16(2):203-204
Objective To investigate the adjunctive therapeutic effect of recombination growth hormone(rhGH) on the elderly patients with pulmonary infection.Methods 53 elderly patients with pulmonary infection were randomly divided into rhGH group(n=25) and control group(n=28).The rhGH group were received hypodermic introl group were received standard therapy.Clinical efficacy were compared between two groups.The level of albumin (ALB),growth hormone (GH),insulin-llke growth factor-1 (IGF-1),leptin (LP) were measured and the body mass index(BMI) was observed in all cases before and after treatment.Results The overall efficacy of rhGH group and control group was 88.0% versus 60.7%.The results showed significant statistical difference between both groups(P<0.05).After treating with rhGH for 10 days,the level of BMI,ALB,GH,IGF-1 and LP were increased in the rhGH group,which were(26.1±4.1)kg/m2;(38.4 ±6.6)g/L;(7.0 +0.9) μg/L;(27.3 ±6.1)μg/L;(6.9 ± 1.1)μg/Lrespectively.And the level of BMI,ALB,GH,IGF-1 and LP were (21.8 ± 3.4 ) kg/m2 ;( 29.5 ± 5.1 ) g/L;( 4.0 ±0.4) μg/L;( 22.0±3.8 )μg/L;( 3.8±0.8 )μg/L in the control group after treatment.The results showed significant statistical difference between both groups(P<0.05).Conclusion There was obvious adjunctive therapeutic effect of rhGH to the elderly patients with pulmonary infection by improving the nutritional state of these patients.

OBJECTIVE:
To investigate the genetic polymorphisms of 21 autosomal STR loci of Fujian Han population and evaluate the forensic application value of GlobalFiler Express kit.
METHODS:
Amplified with GlobalFiler Express kit, DNA samples were obtained from 741 unrelated individuals of Fujian Han population. The population genetics parameters of 21 autosomal STR loci were calculated.
RESULTS:
The 21 autosomal STR loci were found to be no deviation from Hardy-Weinberg equilibration (P > 0.05) and relatively abundant in high polymorphism. Heterozygosity ranged from 0.589 to 0.914, power of discrimination ranged from 0.754 to 0.992, polymorphic information content ranged from 0.520 to 0.940, and power of exclusion ranged from 0.278 to 0.825. The SE33 locus was the highest degree in polymorphism.
CONCLUSION
The 21 STR loci of GlobalFiler Express kit have high value in discrimination power and can be useful in personal identification and paternity test in Fujian Han population.

OBJECTIVETo determine the recognition of healthy medical students on deqi after acupuncture, reveal the qualitative and quantitative rules of deqi and understand whether these rules are the factors of the clinical application of acupuncture therapy.
METHODSThe class questionnaires were used for the investigation study on the understanding of deqi after acupuncture at Hegu (LI 4) or Zusanli (ST 36) in 86 healthy students in the clinical medicine class.
RESULTS(1) Deqi was a kind of complicated compound feelings, with many sensation qualities such as distending pain, distension and pain. (2) Deqi was a kind of mild and moderate sensations. In 10-score credit sys tem of Massachusetts General Hospital acupuncture sensation scale (MASS), the scores of distending pain (4.69 +/- 2.83), distension (4.39 +/- 2.91) and soreness and distension (3.93 +/- 2.93) were around 5 (moderate degree), the scores of stabbing pain (1.89 +/- 2.02) were around 2 (mild degree). (3) The differences in the quantitative scores were significant for stabbing pain, distending pain, distention, soreness and distention and the others before and after treatment (all P<0.05).
CONCLUSIONDeqi of acupuncture is the mild and moderate complicated sensations manifested as distension, soreness, pain and numbness. As the invasive therapy, the filiform needle puncture will bring a certain psychological impacts on the receptors. The subjective sensation is possibly the factor for the patients' selection of acupuncture treatment.

Recombinant expression vector pcDNA3-MCPCD59DP containing human membrane complement regulatory proteins(hCRPs) MCP and CD59 cDNA was constructed successfully by using two independent promoters.After transfected into NIH3T3 cells with calcium phosphate-DNA precipitate method,NIH3T3 pcDNA3-MCPCD59-DP transfectants were obtained by G418 selection.Extraneous genes integration was identified by PCR.The co-expression of human CD59 and MCP at both mRNA and protein levels was confirmed by using RT-PCR and Western blot analysis.Human MCP and CD59 cDNA were integrated in NIH3T3 pcDNA3-MCPCD59-DP genomic DNA after continuous 30 times passages,indicating that NIH3T3 pcDNA3-MCPCD59-DP were stable cell lines.Human complement-mediated cytolysis assays showed that NIH3T3 cells transfected stably with pcDNA3-CD59,pcDNA3-MCP,and pcDNA3-MCPCD59-DP were protected from C-mediated damage and co-expressed human MCP and CD59 provided more excellent protection against C-mediated attack as compared with either CD59 or MCP expressed alone.The dicistronic vector represents an effective and efficacy strategy to overcome C-mediated damage and has potential therapeutic value for effectively controlling complement activation and finally for preventing hyperacute rejection in clinical gene therapy.

To compare the clinical effect of phacoemulsification and middle incision extracapsular cataract extraction ( Ml-ECCE) . METHODS: One hundred and eighty - five eyes of phacoemulsification (137 cases) and 185 eyes of 139 cases for Ml-ECCE from January 2011 to May 2013 were involved in this study. And the ratio posterior capsular rupture during surgery, visual acuity, corneal edema, corneal astigmatism and intraocular pressure post operation were followed up.RESULTS: On 1d after surgery, uncorrected visual acuity in the group of Ml-ECCE was better than that of phacoemulsification group, while from 3d; 1 and 3mo after surgery, no significant difference was found from the above two groups. On 1d postoperation, corneal edema ratio in phacoemulsification group ( 45 eyes ) was higher than that in Ml-ECCE group(20 eyes) ( X2=11. 665, P=0. 0006 ) . No significant difference was found for the ratio of posterior capsule rupture during surgery in these two surgical technique groups(X2=0. 094,P=0. 759). On 1wk;1 and 3mo after surgery, significant difference was found for the average of surgical induced corneal astigmatism between two groups (u=6. 661, 6. 880, 4. 187, P = 0. 00, respectively ). During following up, no significant difference was found for the intraocular pressure between two groups ( u=1. 858, 0. 963, 0. 471, 1. 349, 1. 388; P= 0. 063, 0. 335, 0. 638, 0. 177, 0. 165). lntraocular pressure on 1d postoperation in phacoemulsification and Ml-ECCE groups was higher than before operation ( u = 19. 86, 19. 39, P = 0. 00, respectively). And on 1wk; 1 and 3mo postoperation, intraocular pressure in the operated eyes in both groups was lower than before operation for 2~3mmHg.CONCLUSlON: Although phacoemulsification and Ml-ECCE could both get good visual rehabilitation, with similar visual outcome, no significant effect for intraocular pressure, and no severe complications, the latter one owns the advantage that easier maneuver, quicker recovery, and cheaper instruments needed, which is suitable for the hard nuclei cataract in local hospitals. Ml-ECCE is a safe, effective and easy manipulation for local hospital for large batch of cataract surgeries.
