OBJECTIVETo observe the clinical efficacy difference on vegetative state in children between acupoint injection combined with plum-blossom needle and western medication based on basic treatment.

METHODSForty-eight children of vegetative state were randomized into an observation group and a control group, 24 cases in each one. On the basis of the treatment of transcranial magnetic stimulation apparatus, balancing treatment apparatus and massage, the acupoint injection and tapping method with plum-blossom needle were adopted in the observation group, in which Xingnaojing injection, mouse nerve growth factor (mNGF) injection, monosialotetrahexosylganglioside sodium injection (MSI), compound Danshen injection were divided in 6 pairs and were injected respectively in Baihui (GV 20), Yongquan (KI 1), Fengfu (GV 16), Yamen (GV 15) and the others, 0.5 mL in each acupoint, once a day for continuous 10 days. Additionally, the tapping method with plum-blossom needle was used on the Governor Vessel and Jiaji (EX-B 2) on the back. In the control group, the intravenous infusion was adopted with citicoline sodium injection, mannitol injection and dexamethasone injection. The treatment was given once a day, 20 days of treatment made one session and totally 3 sessions were required in the two groups. The clinical efficacy, the vegetative state score and the mean curing time were observed after 20 days, 40 days and 60 days of treatment between the two groups.

RESULTSThe effective rates were 58.3% (14/24), 70.8% (17/24) and 79.2% (19/24) in 20 days, 40 days and 60 days of treatment in the observation group and 20.8% (5/24), 45.8% (11/24) and 58.3% (14/24) in the control group respectively. The efficacy in the observation group was superior to those in the control group (P < 0.01, P < 0.05). The vegetative state score was improved apparently after 20 days, 40 days and 60 days of treatment as compared with those before treatment separately (all P < 0.05). It was improved obviously at the each time point after treatment in the observation group as compared with that in the control group (3.34 +/- 2.41 vs 2.64 +/- 11.56, 6.20 +/- 1.46 vs 4.34 +/- 1.64, 11.26 +/- 2.63 vs 8.75 +/- 2.18, all P < 0.05). The mean curing time was (45.67 +/- 16.24) days in the observation group, which was shorter apparently than that of (55.34 +/- 4.57) days in the control group (P < 0.05).

CONCLUSIONBased on basic treatment acupoint injection combined with tapping method of plum-blossom needle achieve the reliable efficacy on vegetative state in children.

To construct a recombinant adenovirus containing CDglyES fusion gene, which can directly inhibit human ovarian cancer cell and indirectly inhibit vascular endothelial cell growth. Methods:We constructed prAdCDglyES using a homolo-gous recombination method in bacteria. The prAdCDglyES was transfected to 293 packaging cells using liposome, in which rAdCDgly-ES was packaged and amplified. MTT was used to observe the proliferation inhibition effect of rAdCDglyES on human ovarian cancer cells and the growth inhibition effect of expressing products of rAdCDglyES on ECV-304. Results:The titer of rAdCDglyES was 1 × 1013.3 TCID50/L, whereas the inhibition rate on human ovarian cancer cell SKOV-3 was (83.1±6.3)%. This result is significantly different from the control rAd-LacZ, which had an inhibition rate of (24.1 ± 13.2)% (P<0.01). The concentrated culture supernatant from cells transfected with rAdCDglyES can inhibit ECV-304 cell proliferation at a rate of (78.7 ± 1.6)%. This rate is significantly different com-pared with that of the control with the same concentration of culture supernatant from cells transfected with rAd-CD, with an effect on ECV-304 cell shown by an inhibition rate of (23.9 ± 9.7)%(P<0.01). Conclusion:The results showed that the recombinant adenovirus rAdCDglyES could inhibit human ovarian cancer cells directly and indirectly.

Objective To determine whether the cross-sectional area (CSA)of the calf measured with MRI could stage lower ex-tremity lymphedema (LEL)secondary to gynecological cancer treatments.Methods 148 patients were enrolled in this research.116 females with unilateral LEL and 32 without LEL after gynecological cancer treatments underwent calf MRI and water displacement. Total soft tissue CSA (T),muscle CSA (M)and subcutaneous tissue CSA (S)of affected calf,and difference of T (DT),M (DM) and S (DS)between calves were obtained on MRI at mid-calf level.Volume of affected calf and difference of volume (DV)between calves were obtained by water displacement.Statistical analysis was performed to determine feasibility of MRI measurements for ac-cessing LEL.Results There were close correlations between volume and T or S of affected calf,and between DV and DT or DS of calves.The correlations of stages of LEL with T and S of affected calf as well as DT and DS were stronger than the volume of affect-ed calf and DV (P< 0.01).Multivariate analysis showed more significant differences in T and S than in volume of affected calf,and in DS than in DV between LEL stages (P< 0.05).No difference was found in volume of affected calf and in DV between stage 0 andⅠ. For staging LEL,DS showed the most profound discrimination ability among all measurable parameters.Conclusion DS of calves could be the most reliable parameter recommended for staging and early diagnosis of LEL.

AIM: To investigate the expression pattern of apolipoprotein M (apoM) protein in renal cortex of a-cute renal failure ( ARF) rats with reperfusion. METHODS: Seventy - five male rats were randomly divided into sham operation group (re =25) , ARF group (n =25) and pyrrolidine dithiocarbamat (PDTC) group (n =25) , five subgroups at time points of 3 h, 6 h, 12 h, 24 h and 48 h after reperfusion were set up in each group. The expressions of apoM in cytoplasm and NF - κB p65 in nucleus of renal cortex were detected at the indicated time points. RESULTS: The expression of apoM in ARF group was obviously higher than that in sham operation group ( P <0.01 ) , and two peaks were detected, the first peak was at 6 h after reperfusion, while the second one was from 24 h to 48 h. The tendency of apoM expression in PDTC group was similar to that in ARF group, while the expression in every subgroup was prevalently lower than that in ARF group (P < 0.01). Otherwise, a significant correlation ( r = 0.852, P < 0.01) was found between the expression of apoM and NF -κB p65.CONCLUSION: The results indicate that apoM feasibly take part in the pathogenesis of ARF through the inflammatory reaction mediated by NF - κB.

BACKGROUND: Nitric oxide (NO) is synthesized by catalysis of nitric oxide synthase (NOS). Three distinct isoforms of NOS have been detected in different structures of the guinea pig cochlea. However, there are still rather controversies about the definite localization and expression of NOS isoforms in guinea pig cochlea.OBJECTIVE: To investigate localization and expression of three NOS isoforms in the cochlea of guinea pigs, and to explore the effect of NO on auditory physiology and pathophysiology of inner ear.DESIGN: An observed and controlled study.SETTING: Department of Physiology, Jinzhou Medical College; Department of Orthopedics, the Second Affiliated Hospital of Jinzhou; Department of Otorhinolaryngology, Jinzhou Central Hospital.MATERIALS: The study was performed in Hearing Research Laboratory of China Medical University from May to November 2000. Ten healthy male albino guinea pigs, with body mass of 250-300 g, with sensitive Preyer's reflexes and normal drum membrane and external auditory canal,were selected.METHODS: After anesthesia, guinea pigs were decapitated and the temporal bones were removed immediately. The round and oval windows were opened, perfused with 40 g/L paraformaldehyde, and the specimens were immersed in the same fixative solution for 2 hours. Decalcification of the cochleae was performed in 100 g/L EDTA solution for 1 week. Then the specimens were placed in 250 g/L sucrose solution overnight and embedded in OCT. Cryostat (20 μm) sections were prepared for immunohistochemistry.MAIN OUTCOME MEASURES: Localization and expression of three NOS isoforms in the cochlea of guinea pigs.RESULTS: All data of ten guinea pigs was entered the final analysis without any loss. [1] Neuronal-type nNOS and endothelial-type eNOS immunoreactivity were localized in inner and outer hair cells of the organ of Corti, as well as in spiral ganglion cells. In addition, staining for nNOS and eNOS were also seen in the marginal cells of stria vascularis, spiral ligament cells, and in nerve fibers. [2] Inducible-type iNOS immunoreactivity was also detected in above each structure of the guinea pig cochlea under physiological conditions.CONCLUSION:NO may play an important role in neurotransmission,blood flow regulation, and cytotoxicity.

ObjectiveTo investigate the relationship between liver stiffness and hepatocellular carcinoma (HCC) risk in chronic heptatitis B patients with negative α-fetoprotein (AFP) tests. MethodsFrom September 2012 to August 2014, this study enrolled a total of 82 HBV-relative native HCC patients as the case group. During the same period, a total of 253 chronic hepatitis B patients were also include in this study as the control group. These 253 patients were followed up for six months. All of the two groups were AFP-negative. Liver stiffness was measured in all patients by transient elastography device Fibroscan?. Logistic regression was applied to assess the risk of HCC incidence, and stratum-specific likelihood ratios (SSLR) was calculated.ResultsThe age, liver stiffness measurements and plasma albumin of patients in case group were 53 years old (44-61), 12.00 kPa (7.50-20.75), 43.14 g/L (39.50-46.75) respectively. The age, liver stiffness measurements and plasma albumin of patients in control group were 45 years old (38-56), 8.40 kPa (5.40-13.50), 46.40 g/L (43.75-48.50) respectively. The variables were compared between two groups with unpaired studentt test, and the results were statistically significant (t=4.33, 3.56,
-4.48,P=0.00, 0.00, 0.00). The patients in case group were older, and had higher liver stiffness measurements and lower plasma albumin than that of the patients in control group. Logistic regression analysis showed that HCC incidence was associated with age,male-gender and liver stiffness, and the odds ratios (OR) was 1.053, 2.432, 6.803 respectively. When liver stiffness was<10 kPa, 10.1-15 kPa, 15.1-25 kPa,>25 kPa, SSLR for HCC presence was 0.67, 1.02,1.44, 3.98 respectively.ConclusionsLiver stiffness measured by transient elastography is useful in predicting the risk of HCC incidence in AFP-negative chronic heptatitis B patients. Clinicians needed to carry out close follow-up and appropriate intervention for these patients.
