Objective To observe and compare the efficacy and safety between propofol-fentanyl and propo- fol-ketamine for anesthesia of artificial abortion.Methods 450 ASA physical statusⅠandⅡpatients scheduled for elective artificial abortion were randomized into three groups:P group were given intravenous normal saline 2ml be- fore propofol(n=150) ;PF group were given intravenous fentanyl 1?g/kg then propofol(n=150);PK group were given intravenous ketamine 0.4mg/kg then propofol(n=150).Total dose of propofol,extinction time of lash reflex, heart rate(HR),mean arterial pressure(MAP),pulse oxygen saturation(SpO_2),time to open the eye when called, time of full recovery(answering correctly and walking unaided),discomfort,awareness during operation,self-feeling were recorded.Analysis of date was with SPSS 12.0.P＜0.05 was considered significant.Results No episodes of nausea,vomiting,cardio-cerebral syndrome or awareness were noted in all patients;Total dose of propofol,and extinc- tion time of lash reflex in P group were significantly more than those in PK or PF group(P＜0.05),but there was no difference between PK and PF group;MAP,minimum HR and SpO_2 during operation were obviously lower than preoperation or postoperation in those in P or PF group,minimum HR and SpO_2 during operation in P group were significantly lower than in PF or PK group;Minimum HR and SpO_2 during operation in PK group were lower than preoperation,but its decrease extent was less than that in P or PF group(P＜0.05);Time to eye opening in PF or PK group was significantly less than that in P group(P＜0.05);Time to full recovery were not different in three groups;Incidence of pain on injection in PF group(10%)or PK group(8%)was obviously lower than P group (80%);Incidence of coughing and moving during operation in PF group(8%)or PK group(6%)was obviously less than P group(30%);No difference were noted with respect to degree of comfort,time of full recovery,bleeding vol- ume during operation,time to operation.Conclusion Painless artificial abortion can be preformed effectively and safely with propofol-fentanyl or propofol-ketamine,propofol-ketamine especially fits for painless artificial abortion compared with propofol-fantanyl.

Objective: To explore the mechanism of An-pressing manipulation in improving post-stroke muscle spasticity, by observing the changes of γ-aminobutyric acid (GABA) and glycine (Gly) in plasma and gray matter of L1-L3 spinal cord anterior horn in post-stroke rats with muscle spasticity after An-pressing manipulation intervention. Methods: Ten of 80 adult male Sprague-Dawley (SD) rats were randomly selected as the blank group, and the remaining 70 were used for modeling. The middle cerebral artery occlusion (MCAO) rat model was established by insertion suture occlusion method in the left external carotid artery. Thirty rats with a Longa neurological score of 2-3 points and a modified Ashworth spasticity scale score of 1-, 1+, or 2 were included in the experiment. Using the random number table method, the 30 successfully modeled rats were randomly divided into a model group, an An-pressing tendon group and an An-pressing muscle belly group. Two days after modeling, rats in the An-pressing tendon group and An-pressing muscle belly group received An-pressing manipulation on the tendon and belly of quadriceps femoris muscle respectively, with the pressure of (350±50) g and the frequency of 5 s/time, 15 min per session, once a day for 5 continuous days. After the 5th treatment, the tension of the rat quadriceps femoris muscle was evaluated using the modified Ashworth spasticity scale. The Gly levels in rat plasma and L1-L3 segments of spinal cord were determined by enzyme-linked immunosorbent assay (ELISA). The GABA levels in rat plasma and L1-L3 segments of spinal cord were measured by high performance liquid chromatography (HPLC). Results: The decrease in rat muscle tension scored by the modified Ashworth spasticity scale in the An-pressing tendon group was more significant than that in the An-pressing muscle belly group (P<0.01); the increases in Gly and GABA levels in the rat plasma and L1-L3 segments of spinal cord were more significant in the An-pressing tendon group than those in the An-pressing muscle belly group (all P<0.01). Conclusion: Based on the theory of 'anti-stretch reflex' of tendon organs, the use of An-pressing manipulation to induce the 'anti-stretch reflex' by stimulating the tendon organs can improve the muscle spasticity of rats, which is better than An-pressing the muscle belly. Increased levels of Gly and GABA in rat plasma and L1-L3 segments of spinalcord may be one mechanism of An-pressing manipulation to improve muscle spasticity by stimulating tendon organs.

Objective:To summarize the clinical experiences of pediatric en-bloc kidney transplantation (EBKT) at a single center and explore the measures of improving its efficacy.Methods:Clinical data and outcomes retrospectively analyzed for 38 EBKT children between September 2014 and November 2019 from Department of Urology Affiliated Union Hospital Tongji Medical College Huazhong University of Science & Technology. The pediatric donors were aged (63.6±5.7) days with a weight of (4.1±0.2) kg. And the transplant recipients were aged (28.1±1.4) years with a weight of (48.7±4.9) kg. Serum levels of creatinine and basic profiles of both donors and recipients were recorded at Day 0/7/30/90/80/360 post-EBKT. The postoperative occurrences of such complications such as thrombosis, urine leakage, delayed graft function (DGF), proteinuria and hematoma were measured.Results:The one-year graft survival rate was 76.3%(29/38) and the recipient survival rate 100.0%(38/38). Among 29 recipients with long-term graft survival, no dialysis was required at Week 2 post-EBKT and the serum level of creatinine dropped to normal at Year 1. Thrombosis was a major post-EBKT complication with an incidence of 18.4%(7/38). The other complications included urine leakage (20.7%, 6/29), hematoma (6.9%, 2/29) and primary non-functioning kidney (2.6%, 1/38).Conclusions:As an effective way of expanding the pool of donors, pediatric EBKT is clinically feasible.

Nowadays the role of genetic findings in determining the diagnosis, therapy and prognosis of acute myeloid leukemia (AML) has become more valuable. To improve and validate the detection of clonal chromosomal aberrations in leukemia, we designed a combined application of karyotyping with multiplex reverse transcription-polymerase chain reaction (RT-PCR) and fluorescence in situ hybridization (FISH), and addressed the expression and distribution of fusion genes among the subtypes of Chinese adult patients with de novo AML. Multiplex RT-PCR assays were performed on 477 samples from newly diagnosed AML patients, and cytogenetic data were obtained from 373 of them by R or G banding techniques and those in some cases were confirmed by FISH. The PCR products in some suspected cases were tested by two-directional sequencing. The results showed that except unqualified samples, fusion genes were detected by multiplex RT-PCR in 211 of 474 patients (44.51%), including AML1-ETO, CBFβ-MYH11, PML-RARα, PLZF-RARα, NPM-RARα, MLL rearrangements, BCR-ABL, DEK-CAN, SET-CAN, TEL-PDGFR, TLS-ERG, AML1-MDS1 (EVI-1). In 373 patients, who took both multiplex RT-PCR and karyotype analysis, the detection rate of chromosomal aberrations by using multiplex RT-PCR and karyotyping was 160/373 (42.89%) and 179/373 (47.98%) respectively, and the combination could optimize the detection rate of clonal genetic abnormalities to 216/373 (57.90%). The PCR results from 11 cases "normal" in karyotyping but abnormal in RT-PCR for MLL rearrangements were confirmed by two-directional sequencing. It is concluded that karyotype studies remain the cornerstone for genetic testing; conventional cytogenetics and molecular-based methods are complementary tests for the detection of clonal genetic aberrations in AML, especially for the cryptic or submicroscopic aberrations. Once a genetic marker has been identified by combined analysis, it could be used to monitor residual disease during/after chemotherapy, by quantitative RT-PCR and/or FISH.

BACKGROUND:Previous studies concerning neuromechanism of acupuncture for regulating gastric function mainly focused on peripheral nerve, involving in central nervous system. In particular, there are few studies addressing higher central nervous system.
OBJECTIVE:To explore the effects of acupuncture at Neiguan (PC6) and Zusanli (ST36) on gastric-related neurons in the hypothalamic paraventricular nucleus.
METHODS:Using microelectrode extracellular recording technique, gastric related neurons in the paraventricular nucleus were found in gastric distension rats. Stimulation was conducted for 30 seconds by hand acupuncture at Neiguan and Zusanli. The effects of acupuncture on gastric-related neurons in the paraventricular nucleus were observed.
RESULTS AND CONCLUSION:The discharge of 109 neurons in the hypothalamic paraventricular nucleus of 60 rats was recorded. A total of 56 gastric-related neurons of the 109 neurons were observed. The number of neurons response to acupunctures at Zusanli, Neiguan, Pishu (BL20) and Weishu (BL21) were respectively 44, 47, 29, and 33, with the reaction proportion of 78.57%, 83.47%, 51.79%and 58.93%. Results suggested that there exist gastric distension stimulation and acupuncture stimulations from neurons soma to visceral reaction in the hypothalamic paraventricular nucleus, which simultaneously participates in the regulation of acupuncture on the gastric function.
