ObjectiveTo develop an experimental model of orthostatic hypotension (OH) after spinal cord injury (SCI) in rabbits and investigate the effect of tilting table exercise and Shengmaiyin on it. MethodsRabbit model of OH after SCI were induced by complete transection of spinal cord at the T5 spinal segment and raised to 60° head up tilt (HUT) on a tilting table. Tilting table exercise and Shengmaiyin were applied to different groups for 28 d from 4 days after operation. Systolic blood pressure (SBP) and pulse rate (PR) were observed with non-invasive sphygmobolometer of rabbit 3, 10, 17, 24, 31 d after the operation. Liquid chromatography with electrochemical detection(HPLC-ECD) was used to detect the concentrations of plasma norepinephrine (NE) and epinephrine(E) with horizontal position and HUT 60° on the 31st day. ResultsSBP with HUT 60° in rabbits of combined treatment group was significantly higher than that in rabbits of SCI group on the 24th day after operation,and the drop in SBP from horizontal position to HUT60° was significantly lower than that in rabbits of SCI group. SBP with HUT 60° in rabbits of exercise group and combined treatment group was significantly higher than that in rabbits of SCI group on the 31st day after operation. The drop in SBP from horizontal position to HUT 60° was significantly lower in rabbits of Shengmaiyin group, exercise group and combined treatment group than that in rabbits of SCI group on the 31st day after operation. The concentration of E and NE of SCI group, Shengmaiyin group, exercise group and combined treatment group was lower than that of sham group, but there was no significant difference among these groups. ConclusionThe treatment with tilting table exercise and Shengmaiyin can improve OH after SCI partially in rabbits without involving norepinephrine and epinephrine significantly. The period of treatment can be shorten when both therapies used together.

Objective To evaluate the significance of standardized ultrasound examination of fetal structures in the ifrst trimester (11-13+6 weeks). Methods The ultrasound data of 29 858 fetuses who underwent the ifrst trimester screening were analyzed retrospectively in Beijing Obstetrics and Gynecology Hospital of Capital Medical University from January 2010 to December 2012 and followed up the cases with structural abnormalities and increased nuchal translucency (NT). Results Among 29 858 fetuses, 328 structural defects were detected in 284 fetuses (0.95%) by ultrasound in the first trimester, including fetal hydrops (124 cases), choroid plexus cysts (36 cases), exencephaly (32 cases), gastroschisis (24 cases), exomphalos (22 cases), cardiac defects (19 cases), megacystis (14 cases), spine abnormalities (10 cases), meningoceles/encephaloceles (9 cases), alobar holoprosencephaly (8 cases), hydrocephaly (7 cases), abnormalities of extremities (7 cases), acrania (6 cases), amniotic band syndrome (4 cases), abdominal cyst (3 cases) and conjoined twins (3 cases). Pregnancy was terminated in all cases (115) with exencephaly, gastroschisis, exomphalos, meningoceles/encephaloceles, alobar holoprosencephaly, hydrocephaly,abnormalities of extremities, acrania, amniotic band syndrome and conjoined twins, and the defects were verified by the gross appearance of fetuses. Two cases of megacystis were turned out to be normal during follow-up while 1 case was proved to be aneuploid and 1 other case progressed to multiple abnormalities during the second trimester. Most choroid plexus cysts, except 1 case of aneuploid, were normal during the second and the third trimester follow-ups by ultrasound. Thirteen cases of fetal hydrops were found to be aneuploids and 4 hydrops cases were proved to be complicated with other structural defects during the second and the third trimester. NT was increased in 422 cases (1.41%), among which 122 cases (28.91%) were complicated with structural defects and/or fetal hydrops. Ninty-nine cases with increased NT underwent chromosomal examination and 38 cases were found to be aneuploides. During the follow-up of 298 cases with increased NT who continued pregnancy, 21 structural abnormalities were found, including cardiac defects (14 cases), neural abnormalities (4 cases) and diaphragmatic hernia (3 cases). Conclusion The standardized fetal ultrasound in the first trimester is a effective tool for the screening of aneupolides and major structural abnormalities.

Objective To investigate the effects of Kinesio taping on function of knees in girls. Methods 20 female students were tested the peak torque of centripedal and eccentric contraction of knee flexion and extension with Biodex isokinetic testing at 60°/s angular velocity, with Kinesio taping, placebo taping and without taping. Their amplitude root of mean square (RMS) of surface electromyography of vastus medialis (VM), rectus femoris (RM) and vastus lateralis (VL) were also recorded. Results For centripedal isokinetic contraction, the relative extensors peak torque was the most as Kinesio taping (P<0.01). There was no significant difference in relative flexor peak torque (P> 0.05). Standardized RMS of VM and VL were the least as Kinesio taping (P<0.01), but not significantly different of RF among all the conditions (P>0.05). For eccentric isokinetic contraction, the relative extensor peak torque of both extensors and flexors were the most as Kinesio taping (P<0.01), while the Standardized RMS of VM and VL were the least (P<0.01), but no significant difference was observed in RF (P> 0.05). Conclusion Kinesio taping may enhance the strength of centripedal, eccentric contractions of quadriceps and eccentric contractions of hamstring, and increase the muscle fibers recruitment of VM and VL.

Objective To explore the therapy effect of candesartan plus CSDP on elderly hypertensive patients with renal dysfunction.Methods Eighty elderly patients with essential hypertension and renal dysfunction were selected as our subjects.All subjects were randomly divided into candesartan group and candesartan + CSDP group,every group for 40 subjects.Patients in candesartan group were treated with 4 mg candesartan once per day for 6 months.Patients in candesartan + CSDP group were given CSDP 10 capsules three times / day beside 4 mg candesartan,once per day for 6 months.The levels of Cr,BUN,Ccr changes were measured.Results Two therapy strategies can decrease blood pressure and the decrease rate of blood pressure in candesartan + CSDP group was higher than that of candesartan group.The level of Cr,BUN in patients with candesartan + CSDP group after treatment performing were (104.6 ± 6.5) μmol/L,(6.21 ± 4.80) mmol/L,lower than that in before treatment (196.8 ± 2.6) μ mol/L,(9.84 ± 3.20) mmol/L.And the Ccr increased from (58.1 ± 4.9)ml/min to (117.2 ± 6.4)ml/min.The differences were significant (t =2.213,2.302,2.136,P ＜ 0.05).However the differences between before and after treatment with only candesartan treat weren't significant (P ＜ 0.05).Conclusion Candesartan + CSDP might show a synergistic effect compared with candesartan in term of curing elderly hypertensive patients with renal dysfunction.

Objective:To observe the clinical effect of electroacupuncture (EA) plus pricking-cupping bloodletting therapy for herpes zoster.
Methods:A total of 43 patients with herpes zoster were randomly divided into two groups, 23 cases in the treatment group and 20 cases in the control group. The treatment group was given EA plus pricking-cupping bloodletting therapy. The control group was given oral administration of Aciclovir Tablets, Diclofenac Sodium Dual Release Enteric-coated Capsules, Methylcobalamin Dispersible Tablets, and V itamin B12.
Results: The total effective rate was 87.0% in the treatment group and 70.0% in the control group, with a statistical significance in difference of the total effective rate between the two groups (P<0.01).
Conclusion:The clinical effect is better in the treatment of herpes zoster by EA plus pricking-cupping bloodletting therapy than by medications.

Objective To investigate the distribution of 16S rRNA methylase genes in Klebsiella pneumoniae strains producing Klebsiella pneumoniae ealbapenenase type 2(KPC-2).Methods A total of 37 Klebsiella pneumoniae isolates producing KPC-2 were collected.The minimal inhibitory concentrations (MICs)of these strains to amikacin,gentamyein and netilmicin were determinated by agal dilution method.Six 16S rRNA methylase genes(armA,rmtA,rmtB,rmtC,rmtD and npmA)were detected by PCR.Results The resistant rates to amikacin,gentamycin and netilmicin were 97.3%(MIC50≥1024μg/mL).Among those resistant strains,8 were armr/A positive,25 were rmtB positive,4 were both armA and rmtB positive.and no other 16S rRNA methylase genes were found.The total positive rate of 16S rRNA methylase genes was 78.4%(29/37).Conclusion 16S rRNA methylase genes armA and rmtB ale prevalent in Klebsiella pneumoniae strains producing KPC-2.
