Background Phakic posterior chamber implantable contact lens (PPC-ICL) or phakic posterior chamber Toric implantable contact lens (PPC-TICL) implantation is an effective way for the correction of high myopia or high myopia with astigmia,but it often has residual myopic power.Excimer laser-assisted subepithelial keratectomy (LASEK) can correct the residual myopia following PPC-ICL or PPC-TICL,but its effectiveness and safety deserve attention.Objective This study was to analyze the clinical effectiveness and safety of LASEK for residual myopia after PPC-ICL implantation for extreme high myopia.Methods A prospective cases-observational study was performed,and written informed consent was obtained from each patient before any surgery.Fourteen eyes of 9 patients with residual myopia following PPC-ICL or PPC-TICL for the eyes with spherical equivalent refraction of ≥-20.00 D were collected in the Affiliated Hospital of Guizhou Medical University from July 2010 to March 2015,including PPCICL implantation in 8 eyes and PPC-TICL implantation in 6 eyes.LASEK were performed on the eyes to correct the residual myopic power.Uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),haze,the distance of intraocular lens to lens,corneal thickness,corneal topography,corneal endothelial cell counting,intraocular pressure (IOP) and fundus were examined and compared before and after surgery.The effectiveness and safety of the surgery were evaluated.Results The operation was smooth and no complication was found after surgery in all of the eyes.The UCVA and BCVA were significantly different in the eyes among before surgery,6 months after PPC-ICL implantation and 12 months after LASEK (F =31.360,1.778;both at P＜0.05),and the UCVA after LASEK was higher than BCVA before LASEK.The refractive powers were (-22.27-±4.29),(-3.75±2.25) and (-0.42±0.63) D before surgery,6 months after PPC-ICL implantation and 12 months after LASEK,showing a significant difference among them (F=46.370,P＜0.05),and the refractive power was considerably lower after LASEK than that before surgery and after PPC-ICL implantation (both at P＜0.05).No significant difference was found in IOP or corneal endothelial cell counting in operated eyes among before surgery,6 months after PPC-ICL implantation and 12 months after LASEK (F=1.663,1.055;both at P＞0.05).The distance of intraocular lens to lens was (0.69±0.26)mm in the eyes after LASEK and (0.71 ±0.29)mm in the eyes after PPC-ICL implantation,with no significant difference between them (t =0.192,P＞0.05).Conclusions PPC-ICL or PPC-TICL implantation for the correction extreme high myopia often remains a certain degree of myopia,and LASEK for the correction of residual refractive power is safe and effective.

Objective To study the effect of pelvic autonomic nerve preservation(PANP)on urination and sexual function in total mesorectal excision(TME). Methods Two hundred and forty cases of male rectal cancer patients,divided into the PANP who accept the pelvic autonomic nerve preservation in TME,and the control group of 120 patients who do not.The urination and sexual function were observed and compared.3-year-survival rate,local recurrence rates of the two groups were recorded. Results The urinary disorder rates,erective disorder rates and ejaculation disorder rates of PANP group were 30.8%,28.3%and 34.2%,while values of control group were 55.0%、60.0%and 62.5%.The difference between them had statistical significance(P<0.05).The 3-year-survival rate and local recurrence rate of PANP group were 9.4%and 75.0%.The 3-year-survival rate and local recurrence rate of control group were 9.0%and 65.0%.There was no significant difference between them(P>0.05). Conclusion The PANP technique in TME could improve the urinary and sexual function of male patients without affect the prognosis.

OBJECTIVETo observe the effect of detoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn on carotid intima-media thickness (IMT), plaque integral and plaque stability related serum indexes of patients with carotid atherosclerosis.

METHODSixty and four cases of carotid artery atherosclerosis patients were assigned randomly to 2 groups: detoxifying and blood circulation activating treatment group (treatment group, 32 cases) and control group (32 cases). Patients in treatment group were treated with capsules of extraction of polygonum cuspidatum and hawthorn, 1 pill po, bid (dosage of administration: polygonum cuspidatum extraction 5.33 mg x kg(-1) x d(-1), hawthorn extraction 5.0 mg x kg(-1) x d(-1)); patients in control group were treated with lovastatin 20 mg po, qd (dosage of administration: 0.33 mg x kg(-1) x d(-1)). The course of treatment was six months. To observe changes of IMT, plaque integral, and detect the level of plaque stability related serum indexes such as Hs-CRP, MMP-1 and TIMP-1.

RESULTAfter 6 months of treatment, in control group one patient quit the clinical trial because of liver dysfunction and one patient was rejected because of having not followed the therapeutic regimen. 32 cases in treatment group and 30 cases in control group were analyzed. The results showed that IMT and plaque integral of treatment group decreased significantly after the treatment (P < 0.05, P < 0.01), and there was no significant difference compared with control grope. Serum Hs-CRP, MMP-1 and MMP-1/TIMP-1 decreased after the treatment (P < 0.05, P < 0.01), and the treatment group was superior to control group in decreasing serum Hs-CRP (P < 0.05).

CONCLUSIONDetoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn has good effect of anti-atherosclerosis and promoting plaque stability. Its mechanism might be related with anti-inflammation and inhibiting degradation of extracellular matrix, and deserves further studies.

OBJECTIVETo observe the effects of blood activating wind dissipating acupuncture (BAWDA) on blood pressure (BP) of prehypertension (PHT) patients.

METHODSTotally 60 PHT patients were assigned to the control group and the acupuncture group according to random digit table, 30 in each group. All patients were intervened by life style. BAWDA was additionally performed in patients in the acupuncture group for 6 weeks (30 times). The improvement of BP after intervened by acupuncture was observed. BP success rates and the proportion of PHT progressing to hypertension (HT) were also observed after 6-week intervention of acupuncture and at 1-year follow-up.

RESULTSSystolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after 6-week intervention in the acupuncture. The BP control rate was 56.7% (17/30 cases) in the acupuncture group vs.10.0% (3/30 cases) in the control group with statistical difference (chi2 = 14.70, P < 0.01). At 1-year follow-up BP success rate was 36.7% (11/30 cases) in the acupuncture group, remarkably higher than that of the control group [13.3%, (4/30 cases)] (chi2 = 4.36, P < 0.05).

CONCLUSIONSBAWDA showed BP regulating roles in a gradually stable decreasing tendency. It also could elevate BP success rate of PHT, and reduce the risk of PHT progressing to HT.
