The wavelength of infrared rays,beyond that of red visible light in optical spectre,ranges from 0.76 to 1000.00 μm.In clinic,infrared rays include a near-infrared part(with the wavelength ranging from 0.76 to 1.5μm)and a far-infrared part(with the wavelength ranging from 1.5 to 400μm).The far-infrared rays,having a wavelength ranging from 6 to 14 μm,are critical for human health and lives.The far-infrared rays have many biological functions including extending blood capillary,increasing blood flow,enhancing metabolism and repair,accommodating organism disequilibrium,etc.The main biological effect of far-infrared rays is cell activation which can induce a senes of biochemistry and histochemistry changes of calls.With the help of far-infrared rays,human body can be in a healthy status.The main clinical applications of far-infrared rays include auxiliary diagnosis,softening inflammation and pain.tissue repair,sterilization,tumor depression,rewarming from hypothermia,and so on.Far-infrared rays play active functions on human body through caloric effects.Now they are developed to be applied in partial medical fields.The emphases of the future studies are about the effects of far-infrared rays based on molecular biology researches and about the extensive applications of far-infrared rays in medicine.

ObjectiveTo seek an effective protocol fortreating spinal cord injury-induced limb dysfunction by comparing the therapeutic effects of electroacupuncture at Huatuo jiaji points plus Du meridian points versus conventional electroacupuncture. MethodForty patients with spinal cord injury-induced limb dysfunction were allocated, using a random number table, to treatment and control groups, 20 cases each. Both groups were treated with ganglioside and routine rehabilitation therapy. In addition,the treatment group received electroacupuncture at Huatuo jiaji points and Du meridian points and the control group, conventional acupuncture. Lower limb function was assessed using ASIA Motor Score, Sensory Score and the MBI in the two groups of patients before treatment and after one and two courses. The clinical therapeutic effects were evaluated.ResultThere was a statistically significant pre-/post-treatment difference in lower limb dysfunction in both treatment and control groups (P<0.05). The improving effect was better in the treatment group than in the control group (P<0.05,P<0.01).ConclusionElectroacupuncture at Huatuo jiaji points and Du meridian points has a definite therapeutic effect on spinal cord injury-induced limb dysfunction. It is superior to conventional electroacupuncture.

OBJECTIVE:To explore the safety and effects of liver function in patients with liver cirrhosis following virus B hepatitis(called“hepatitis B”for short)on drug half-life and analgesic effect of target controlled infusion of remifentanil. METH-ODS:100 patients with liver cirrhosis following hepatitis B underwent liver and gallbladder surgery under selective general anesthe-sia were collected from our hospital and divided into group A(mild abnormal liver function)and group B(severe abnormal liver function,3 cases withdrew from the test and 47 cases completed the test),with 50 cases in each group,according to Child-Pugh grading of liver function. Both group were given phenobarbital sodium 0.1 g+scopolamine 0.3 mg intramuscularly 0.5 h before oper-ation;midazolam 0.04 mg/kg+propofol 1.5 mg/kg+atracurium 0.6 mg/kg intravenously;target controlled infusion of Remifentanil hydrochloride for injection during operation with 0.125-0.250 μg/(kg·min). The distribution half-life and the elimination half-life of remifentanil were determined, and temperature pain perception threshold (tPDT) and electrical pain perception threshold (ePDT) were measured immediately after the operation;the occurrence of ADR was observed. RESULTS:The distribution and elimination half-life of remifentanil were (4.52 ± 1.25)min and(24.64 ± 1.30)min in group A and (4.68 ± 1.31)min and(25.45 ± 2.08)min in group B respectively,there was no statistical significance between 2 groups(P>0.05). tPDT and ePDT of group A were(8.88± 1.66)mA and(1.54±0.09)mA respectively,and those of group B were(9.16±1.58)mA and(1.34±0.15)mA,there was no sta-tistical significance between 2 groups (P>0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:The abnormal liver function of patients with liver cirrhosis following hepatitis B have no significant effect on drug half-life and analgesic effect of remi-fentanil with good safety.

Objective:To synthesize poly (2-ethyl-2-oxazoline)-poly(lactic acid) copolymer (PEOz-PLA), prepare pH-sensitive paclitaxel-loaded polymeric micelles, and evaluate the in vitro properties. Methods: The structures of all the synthesized copolymers were confirmed by 1 HNMR and Fourier transform infrared spectroscopy ( FTIR) . The drug-loaded micelles were prepared by a dialysis method. The micelles solution was freeze-dried and the lyoprotectants were screened. The critical micelle concentrations ( CMC) of the copolymers were measured by pyrene fluorescent probe technique. The distribution of particle size was measured by dynamic light scat-tering ( DLS) . The in vitro release behavior of the loaded micelles at different pH conditions was studied by a dialysis method. Re-sults:The CMC of micelles was 25. 63 mg·ml-1 . When 10% polyethylene glycol 4000 was used as the lyoprotectant, the re-solubili-ty of micelles was good and the distribution of particle size was narrow. The drug loading rate of micelles was 8. 12% and the encapsu-lation efficiency was 69. 33%. The average particle size of freeze-dried micelles was 183. 7 nm. The in vitro release of the drug-loaded micelles showed that the drug released slowly at pH 7. 4 and fast at pH 5. 0, which indicated that the change of pH could affect the drug release. Conclusion:The preparation of PEOz-PLA polymer micelles is simple. The particle size, entrapment efficiency and drug loading are controllable. The micelles have a certain sustained-release effect, which provides basis for further pharmacological study and clinical application.

In this research, we apply the antisense strategy to study the function of IGF- I in human hepatoma lines(7402) by Lipofectin mediated gene transfer. The effect of antisense IGF-I on the expression of MHC and the sensitivity of LAK cytotoxicity of tumor cell were studied. The results showed that human hepotoma lines(7402) were transfected with an amplifiable antisense IGF- I gene. The expression antisense IGF-I RNA in the transfected cells after hygromycin resistant selection was confirmed by northern blot analysis. The transfectants expressed higher level of MHC class I and class II molecules. The susceptibility of the transfected cell to LAK cytotoxicity was greater than that of 7402 parent cells(P

The determination of vitamine D in fortified milk powder was carried out by means of HPLC. Its pre-treatments include extraction of fat, sap onification, isolation of the unsaponifiable matters, and digitonin-celite and bentonite column chromatography. The HPLC was performed with 15cm ? 4mm column of silica 5m 0.7% ethyl alcohol in iso-octane as mobile phase, at 254nm. Only 12 grams of sample which contained 400-500 IU vitamin D/100 g were used. Within the sample there were relatively large amounts of interfering materials such as fats, sterols,?-carotene, vitamin A, vitamin E and their decomposed products, but they could be separated by the above method. The recovery rate of vitamin D was 81% with standard deviation of 0.39?g/100g. This method could also be applied to other samples such as fortified cakes, confectionaries, infant foods and "Mairujing" (milk maltose mixture powder) etc.

OBJECTIVE:To systematically review the clinical efficacy and safety of sirolimus(SRL)versus tacrolimus(Tac) for anti-rejection after renal transplantation,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed,EMBase,Medline,Science Direct,Cochrane library,CJFD,VIP and Wanfang Database,randomized controlled tri-als(RCT)about SRL(test group)versus Tac(control group)for anti-rejection after renal transplantation were collected. Meta-anal-ysis was performed by using RevMan 5.2 software after data extraction and quality evaluation. RESULTS:Totally 5 RCTs were in-cluded,involving 594 patients. Results of Meta-analysis showed,there was no significant difference in the incidence of acute rejec-tions [RR=1.26,95%CI(0.82,1.93),P=0.30],graft loss rate [RR=0.91,95%CI(0.32,2.55),P=0.85] and mortality rate [RR=0.87,95%CI(0.34,2.22),P=0.77] in 2 groups;while the infection rate in test group was significantly lower than control group, the difference was statistically significant [RR=0.13,95%CI(0.04,0.40),P<0.001]. CONCLUSIONS:Compared with Tac,SRL has the same anti-rejection effect after renal transplantation,not changed graft loss rate and mortality rate,but reduced the infection rate with higher safety.
