Objective: To observe the effect of muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting in improving nail fold microcirculation in the patients with shoulder-hand syndrome (SHS) after stroke, and the effects on hemorrheology, calcitonin gene-related peptide (CGRP) and serum substance P (SP). Methods: A total of 72 patients were randomized into an observation group and a control group by the random number table method, with 36 cases in each group. The control group was treated with physical rehabilitation training, and the observation group was treated with additional muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting treatment. The treatment course lasted for 4 weeks. After treatment, the clinical efficacy of the two groups was compared. The changes in shoulder-hand syndrome scale (SHSS), simplified Fugl-Meyer assessment-upper extremity (FMA-UE), visual analog scale (VAS), activities of daily living (ADL), traditional Chinese medicine (TCM) syndrome score, nail fold microcirculation hemorheology indictors [whole blood viscosity (high-shear, low-shear), hematocrit, erythrocyte sedimentation rate (ESR)], CGRP and SP levels were observed. Results: The total effective rate in the observation group was 86.1％, higher than 63.9％ in the control group (P<0.05). The overall curative effect in the observation group was better than that in the control group (P<0.05). After treatment, the scores of pain sensation, edema, external turn and rotation of the arm in SHSS, and the total score were significantly decreased in both groups (all P<0.05), and each score in the observation group was lower than that in the control group (all P<0.05). After treatment, the scores of VAS and TCM syndrome in both groups decreased significantly (all P<0.05), and the scores of FMA-UE and ADL increased significantly (all P<0.05). The scores of VAS and TCM syndrome in the observation group were lower than those in the control group (both P<0.05), and the scores of FMA-UE and ADL were higher than those in the control group (both P<0.05). After treatment, the whole blood viscosity (high-shear and low-shear) and hematocrit in both groups decreased obviously (all P<0.05), and ESR increased obviously (both P<0.05), and the whole blood viscosity (high-shear and low-shear) and hematocrit in the observation group were lower than those in the control group (all P<0.05), and ESR was higher than that in the control group (P<0.05). After treatment, the peritubular state, loop shape, blood flow and total score of nail fold microcirculation in both groups decreased significantly (all P<0.05), and each score in the observation group was lower than that in the control group (all P<0.05). After treatment, SP in both groups decreased obviously (both P<0.05), CGRP increased obviously (both P<0.05), and SP in the observation group was lower than that in the control group (P<0.05), CGRP was higher than that in the control group (P<0.05). Conclusion: Compared with conventional physical rehabilitation training, muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting treatment can significantly reduce the clinical symptoms of SHS, promote the recovery of physical functions, improve the nail fold microcirculation and hemorrheology indictors, and regulate the serum cytokine levels such as CGRP and SP.

Objective To compare the safety,effectiveness and predictability of laser in situ keratomileusis (LASIK) with fem- tosecond laser (IntraLase) and mechanical microkeratome (Moria M2,head 90?m).Design Prospective clinical study.Participant 148 patients (274 eyes) with high myopia received operation of LASIK.Method The patients were assigned to receiving LASIK with corneal flap creation by Intralase femtosecond laser (134 eyes of 76 patients) or Moria 90 keratome (140 eyes of 72 patients),both groups receiving eximer laser ablation with VISX Star S4.Followed-up examinations such as visual acuity,refraction,wavefront aberra- tion,etc.were scheduled for 1 day,1 week,1 month and 3 months postoperatively.Main Outcome Measures Visual acuity,refrac- tion,wavefront aberration,Schirmer test and tear film breakup time(BUT).Results At 3 months after operation,108 eyes (80.6%) of IntraLase group had UCVA better than or equal to BSCVA preoperatively,showing no statistically significant difference to microker- atome group (116 eyes,82.9%,P=0.642).The mean residual spheroequivalent of refraction of IntraLase group was -0.49?0.70D,show- ing no statistically significant difference to microkeratome group (-0.56?0.83D,P=0.448).The mean Schirmer test of Intralase group was 9.5?4.0mm,showing no statistically significant difference to microkeratome group (9.5?7.2mm,P=0.950).The mean BUT of IntraLase group was 7.9?4.3s,showing no statistically significant difference to microkeratome group (8.08?5.48s,P=0.869).The postoperative higher-order aberrations of the IntraLase group was 0.480?0.133?m,lower than that of microkeratome group (0.578?0.169?m,P=0.034). Conclusions Thin-flap LASIK with femtosecond laser and mechanical keratome flap creation are both safe,effective for the correction of high myopia,showing good predictability and stability.Femtosecond laser has slightly better clinical outcomes than microkeratome.

Objective To investigate the influencing factors for eye cyclotorsion and pupil centroid shift during LASIK.Design Non-controlled retrospective case series.Participant 131 patients (262 eyes) with myopia received bilateral LASIK.Methods Eye cy- clotorsion and pupil centroid shift were measured with Custom Vue~(TM) software during operation and compared with age,gender,right or left eye,flap-making method,spherical equivalent (SE),pupil diameter before and during operation.Main Outcome Measures The de- gree of eye cyclotorsion and distance of pupil centroid shift during LASIK.Results The mean eye cyclotorsion during LASIK was 3.07??2.07?(0?-8.6?).The mean pupil centroid shift was 0.33?0.14 mm (0.04-0.51 mm).The eye cyclotorsion was relevant to preoperative pupil size,difference of pupil size before and during operation,and preoperative SE (r=0.188,0.156,0.130,all P7.0 mm was higher than that of with pupil diameter≤7.0mm (3.35??2.17?,2.71??1.89?,P=-0.014).Pupil centroid shift was higher in fight eyes than that in left eyes (0.39?0.12 mm,0.28?0.13 mm,P=0.000).Conclu- sion Eye cyclotorsion and pupil centroid shift during LASIK can be measured with Custom Vue~(TM) system.The eye cyclotorsion may be influenced by the preoperative pupil size.The pupil centroid during LASIK was more significant in the right eyes than in the left eyes.

Objective To explore target organ damage in the youth with pre-hypertension. Methods 77 consecutive youth visiting our institution form 2008 to 2010 were divided into pre-hypertension group (n=32) and control group (n=45). The relevance of left ventricular mass index (LVMI), left ventricular end-diastolic diameter (LVDd), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), carotid plaque intima-media thickness (IMT) and glomerular filtration rate (GFR) were compared. Results The blood pressure of pre-hypertension group was higher than that of control group, and the pre-hypertension group followed higher family hypertension history (P<0.05). There was no difference in LVDd, IVST, LVPWT, carotid plaque IMT and GFR between 2 groups (P>0.05). Compared with the control group, LVMI increased (P<0.05) and the E/A ratio decreased (P<0.05). Conclusion Target organ damage in pre-hypertension youth is salient compared with changes in renal function and damage of arteriosclerosis, and heart damage is more often occurred in the obese youth with pre-hypertension.
