Objective To explore the effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage. Methods Seven eyes of 7 patients with neovascular glaucoma combined with vitreous hemorrhage underwent vitrectomy combined with phacoemulsification, panretinal photocoagulation, and trabeculectomy. The preoperative visual acuity ranged from light perception to 0.2, and the mean preoperative intraocular pressure was 54 mm Hg (38-64 mm Hg)(1 mm Hg=0.133 kPa). The mean follow-up was 8 months (6-15 months). Results The postoperative visual acuity ranged from light perception to 0.4, and the mean postoperative intraocular pressure was 17 mm Hg (10-30 mm Hg) which was significantly lower than preoperative one ( P

One child was hospitalized because of repeated cough and sputum. The biopsy diagnosis in local hospital was cystic lymphangioma in retropharyngeal space. We carried out transoral incision and drainage by catheter under general anesthesia. Put into the surgical cavity a suction drainage tube, and injected 5 mg dexamethasone and 8mg Bleomycin. He had nasogastric liquid diet after operation. We removed the suction drainage tube two weeks later. No recurrence was found following up over two years.

Objective To study the effects ofautologous bone marrow mononuclear cells (BMMCs)transplantation during coronary artery bypass gafting (CABG) on myocardial infarct size. Methods Forty myocardial infarction patients diagnosed by coronary angiography (CAG) and SPECT and confirmed at surgery were enrolled and randomly assigned CABG alone (group Ⅰ) or CABG with intramyocardial or intracoronary injection of autologous BMMCs (group Ⅱ), 20 cases in each group. Baseline and followed up evaluations included SPECT and NYHA-FC before and after 6 months operation, recorded the major adverse cardiac events (MACE) at the same time. The number of autologous BMMCs injected was (6.84 ± 2.88) ×107 in group Ⅱ. Results There was no procedure-related complication during 6 months followed up in all patients. After 6 months operation,left ventricular ejection fraction in group Ⅱ was significantly higher than that in group Ⅰ [(57.40 ±5.21)% vs. (50.75 ±5.88)%,t =3.79,P＜0.05],NYHA-FC in group Ⅱ was significantly improved than that in group Ⅰ [(1.30 ± 0.47) grades vs. (1.85 ± 0.59) grades, t = 3.27, P ＜0.05],SPECT showed myocardial infarct size in group Ⅱ was significantly lower than that in group Ⅰ[(14.57 ±5.20)% vs. (20.45 ±5.18)% ,P ＜0.05]. Conclusion Autologous BMMCs transplantation during CABG is safe and feasible, which can reduce the myocardial infarct size in patients with myocardial infarction.

ObjectiveTo investigate the value of urinary BNP for diagnosis of chronic heart failure (CHF). MethodsThe levels of Urinary BNP and plasma BNP were measured by microparticle enzyme immunoassay (MEIA) in 83 patients with CHF and 30 control subjects. The heart function was classified according totheNYHAcriteria. Leftventricularejectionfractions(LVEF)weremeasuredby echocardiology. ResultsThe level of urinary BNP in patients with CHF was[90. 0(38. 3 -209. 5 )]ng/L and the level of plasma BNP was[680. 0 ( 289. 7 - 1543.5)]ng/L, both of them were much higher than those in healthy subjects,[17. 0 ( 13.0 - 33. 0)]ng/L and[84. 5 ( 56. 0 - 158.0 )]ng/L, respectively (P＜0. 01 ). The concentrations of urinary BNP increased gradually with more severe symptoms ( NYHA cl ass Ⅰ -ⅣV ). The level of urinary BNP was positively correlated with NYHA class ( r = 0. 742, P ＜ 0. 01 )and the level of plasma BNP (r =0. 842,P ＜0. 01 ) while negatively related with LVEF (r = -0. 801 ,P ＜0. 01 ). The level of urinary BNP in patients with LVEF ＜ 40％ was[143.0 ( 85. 0 - 258.0)]ng/L , which was much higher than that in patients with LVEF≥40％ ,[31.5( 17.3 -38. 8)]ng/L, (P ＜0. 01 ). At a decision threshold of 36. 5 ng/L, the urine BNP assay demonstrated a clinical sensitivity and specificity of 84％ and 80％ ,respectively. In this study,the area under the curve(AUC) was 0. 905. ConclusionUrinary BNP is a new candidate marker for the diagnosis of CHF,it provides a similar accuracy with plasma BNP.

BACKGROUND:Coracoclavicular ligament reconstruction with transclavicular-transcoracoid driling is an effective surgical technique to treat acromioclavicular dislocation. A good driling in the clavicle leads to a perfect bony tunnel and a good surgery. OBJECTIVE: To observe the effects of different driling positions of the clavicle on the location of bony tunnels in coracoclavicular ligament reconstruction. METHODS:Sixty three-dimensional digital models of the clavicle and coracoid process were constructed by Mimics13.0. Virtual transclavicular-transcoracoid bony tunnels were established according to different surgical planes with different driling positions in the clavicle. Parameters of these bony tunnels were measured, and the safety was evaluated. Option 1: The driling was made 30 mm distal to the clavicle, located in the center of the front and rear edges of the clavicle surface. Option 2: The driling was made 40 mm distal to the clavicle, located in the center of the front and rear edges of the clavicle surface. Option 3: The driling was made at the straight line of tapered nodule tip and the midpoint of the base of the coracoid process, located at the rear edge of the clavicle upper surface. RESULTS AND CONCLUSION: Bony tunnels in option 1 were extremely on the inside of the coracoid. Bony tunnels in options 1 and 2 were not in the center of clavicle. Bony tunnels in option 3 were in the center of both clavicle and coracoid. The method of locating the driling position with a certain distance to the distal clavicle leads to different results in man’s and woman’s models. To ensure that the bony tunnel can pass through the center of clavicle and coracoid, it is suggested to dril at the straight line of tapered nodule tip and the midpoint of the base of the coracoid process and nearby the rear edge of the clavicle upper surface.

OBJECTIVE: To establish an HPLC method for the determination of the concentration of vancomycin in human serum. METHODS: Serum samples were centrifuged after serum protein was precipitated by 20% metaphosphoric acid. The separation was performed on Hypersil C18 column with mobile phase consisted of acetonitrile-0.012 5 mol?L-1 potassium dihydrogen phosphate buffer (10 ∶ 90) at flow rate of 0.8 mL?min-1. The detection wavelength was set at 236 nm and column temperature was set at 25 ℃. RESULTS: The average relative recovery rate of vancomycin in low, medium and high concentrations (2.5,30.8,150.4 mg?L-1) were 99.8%, 101.1% and 98.9% respectively. The inter-day and intra-day RSD were less than 2.5%(n=5). The limit detection of vancomycin in serum was 2.0 mg?L-1. The linear range was within 2.0～170.0 mg?L-1(r=0.999 8). CONCLUSION: The method is simple, accurate, and rapid for the monitoring and phamacokinetic studies of vancomycin in human serum.

Aim To investigate the periphery analge-sic effect of myricetin on a rat model of inflammatory pain and the mechanism. Methods Rat models of in-flammatory pain were induced by complete Freund ’ s adjuvant ( CFA) injection in left hindlimb plantar cen-ter. The thermal withdrawal latency ( TWL) was meas-ured before and after CFA or myricetin treatment. Elec-trophysiological method was used to identify the effect of myricetin on the action potential frequency and the voltage dependent potassium channel currents in small DRG neurons. Results Rats with CFA injected showed thermal hyperalgesia ( P <0. 05 ) and TWL in-creased significantly after myricetin intraperitoneally in-jected ( P <0. 05 ) . Current clamp recording showed the action potential frequency of small DRG neurons in rats was inhibited by myricetin ( P<0. 01 ) and voltage calmap recording showed the inhibitory effect of myr-icetin was enhanced by calcium depended potassium channel currents ( P<0. 05 ) . Conclusion Myricetin exerts periphery analgesic effect by enhancing calcium depended potassium channel currents and inhibiting excitability of small neurons of dorsal root ganglion.
