Study on 410 pregnant women had babies at Obstetric Department, Sa Dec General Hospital between March and August 2002, who underwent episiotomy or had perineal laceration, followed by swelling, edema, and painful sutures. All participants were divided into 2 groups: group of women had born babies at even dates were treated by 25% magnesium sulfate cold solution, and group of women had born babies at odd dates treated by cold placebo pad. Results: magnesium sulfate solution has endosmotic effect, leads to reduce swelling and edema. Pain relief effects were similar between 2 groups but magnesium sulfate cold solution was likely to have faster improvement in perineal edema and urination. Using cold magnesium sulfate saturated pad for nursing care after episiotomy is simple, easy method and has fast effects.

To prepare polyrotaxane-camptothecin conjugates and evaluate its anti-tumor effect, polyrotaxane-camptothecin conjugates were successfully synthesized, and the release behavior was performed; MTT assay and cell morphology were used to examine the inhibition of cells' proliferation effect in vitro. The experimental study of the antitumor effect on S180 mice in vivo was also performed to further evaluate the anti-tumor effect of conjugate. The result showed polyrotaxane-camptothecin conjugates can effectively inhibit the proliferation in a dose dependent effect. In vivo study and cell morphology observation of S180 mice showed significant decrease in growth of tumor, degree of tumor infiltration and blood vessel number. The result indicated anti-tumor mechanism may be through affect the angiogenesis and reduced blood supply to tumor cells and then leading to necrosis.

Background:Resistance to antibiotics due to extended \ufffd?spectrum \ufffd?Lactamase (ESBL) which increased quickly, made treatment much more difficult. However, this matter was not enough to be concerned in our country. Objectives: To investigate the prevalence of ESBL producing among clinical isolates of E.coli, K.pneumoniae and Enterobacter spp and the classification of ESBLs gene by PCR. Subjects and method: 663 strains, including 248 E.coli, 393 K.pneumoniae, 22 Enterobacter spp, isolated from patients in Viet Tiep hospital (Hai Phong), Bach Mai and Pediatric hospital (Ha Noi). ESBLs were detected using modified double \ufffd?disc method. The classification of ESBLs producing strains was implemented by PCR. Results:the percentage of ESBL producing in E.coli, K.pneumoniae and Enterobacter spp is 20.2; 18.3 and 36.4%, respectively. The ESBLs producing strains were co \ufffd?resistant to most of the tested antibiotics. These strains were prevalent in intensive care units (sputum or respiratory fluid samples). TEM, SHV, CTX \ufffd?M, OXA were 87.7; 62.3; 24.6 and 12.3%, respectively. They were detected alone or in combination in the same strain. Conclusion: The rate of ESBLs producing strains is high. ESBLs were marker for multi \ufffd?drug resistance. TEM and SHV type ESBLs are most prevalent in the tested strains.

Background: In the procedure of tendon transfer to treat low radial nerve palsy, recovering movement amplitude for toes is not difficult. It is more important to select the appropriate motive muscle. Previously, pillar muscle was commonly used as motivation for stretching fingers, but many authors opposed this because it\u2019s affecting the function of the hand. Objectives: To evaluate the clinical features of low radial nerve palsy and the outcomes of the treatment of non-recoverable low radial nerve palsy by Smith's procedure of tendon transfer. Subjects and methods: 36 patients suffering from irreversible low radial nerve palsy were treated by Smith's procedure of tendon transfer from Jan 2000 to Jan 2008. Mean follow-up was 23 months. Outcomes assessment was based on Tajima's criteria. Results: All 30 patients were satisfied with the operation and were greatly improved both their functional and aesthetic aspects. In term of biomechanics, the Flexor Carpi Radialis (FCR) is more suitable for reconstruction of the Extensor Digitorum Communis (EDC) in comparison with the flexor carpi ulnaris (FeU) or the power density spectrum. The patients showed good movements of the wrist and fingers/ the thumb moved independently with satisfactory extension and abduction/ the grip strength was rapidly improving. Conclusions: The use of the FCR for reconstruction of the EDC is a suitable choice and Smith's procedure of tendon transfer is a good procedure for the treatment of irreversible radial nerve palsy.
