Objective To observe the clinical effectiveness of alprostadil combined to pancreatic kininogenas in the treatment of gerontal diabetic peripheral neuropathy.Methods Totally 90 gerontal patients with diabetic peripheral neuropathy were randomly divided into three groups,the first group received the treatment of mecobalamin,the second group received mecobalamin plus pancreatic kininogenas,the last group received mecobalamin,alprostadil and pancreatic kininogenas (30 cases for each).The course of treatment was 4 weeks,the nerve conduction and effective rate of 3 groups were compared after treatment.Results Compared with the first group(53.3％),the total effective rate was significantly improved in the second group (80.0％)and the third group(100.0％) (P＜0.05).After treatment,the therapeutic effect of every group was boosted,and the second group was better than the first group,and the last group was best(P＜0.05).Conclusions Alprostadil combined to pancreatic kininogenas is effective and safe for the treatment of elderly diabetic peripheral neuropathy.

Objective To investigate the effect of transurethral holmium YAG laser in treatment of bladder calculi.Methods F5 laser fiber in the holmium YAG laser was used to treat 40 patients with bladder calculi.Then the effect was observed.Results All 40 cases were successfully done by the operation time range from 15 to 120 minutes.There were no major complications,such as TRUS,bladder rupture or major bleeding.There was no residue stone.Conclusion F5 laser fiber in the holmium YAG laser treatment could be protected by the transurethral scope.It was safe,effective and has shorter operation time in treatment of bladder calculi.

Objective To investigate the risk factors of cerebral palsy in newborns with periventricular leukomalacia(PVL).Methods Sixty-one infants with sequela of cerebral palsy among 806 neonates born at the Second People'S Hospital of Liaocheng,Shandong,China,during December 2000 to November 2005 were studied for its etiology.Diagnosis of cerebral palsy in 26 of the 61 infants was established by type B ultrasonic scanning or magnetic resonance imaging(MRI)for the head at least twice and excluded of other diseases.Thirty-five infants without PVL hospitalized at the same hospital were enrolled as control group during the same period.Logistic regression analysis was performed for the risk factors of PVL. Results Twenty-six infants were diagnosed as PVL.accounting for 42.6％of those with cerebral palsy.Main high-risk factors of PVL included severe asphyxia(x3),low gestational age(x1),intraventricular hemorrhage(x14)and low blood pressure(x8),with odds ratios of 2.843,3.575,3.268 and 1.947,respectively,and a fitted regression model as logistic(P)=β0+0.7952 x3-1.428x1-1.328 x14+0.8256x8.Pregnant hypertension,neonate respiratory distress syndrome(NRDS),and intrauterine infection could also affect occurrence of PVL,all with statistical significance(P＜0.05).Conclusion PVL is one of main causes of cerebral palsy,with severe asphyxia,low gestational age,intraventricular hemorrhage and low blood pressure as main high-risk factors.

BackgroundQuality of life， as a major criterion for judging the clinical outcome of ovarian cancer patients， can be affected by adverse psychological symptoms of patients. Meanwhile， fear of disease progression， as a frequent psychological symptom among cancer survivors， is significantly influenced by metacognition， while there is a paucity of research into the specific correlation among the three in patients with ovarian cancer. ObjectiveTo explore the correlation among fear of disease progression， metacognition and quality of life in patients with ovarian cancer， and to test the role of fear of disease progression in the relationship between metacognition and quality of life， so as to provide references for improving the quality of life in patients with ovarian cancer. MethodsA total of 135 patients with ovarian cancer hospitalized in Cangzhou People's Hospital of Hebei Province from January 2019 to December 2022 were selected. All subjects were requested to complete the Functional Assessment of Cancer Therapy-Ovarian Cancer （FACT-O）， Fear of Progression Questionnaire-Short Form （FoP-Q-SF） and Metacognition Questionnaire （MCQ） to assess their quality of life， fear of disease progression and metacognitive level. Pearson correlation analysis was adopted to examine the correlation among the above scales. Process v3.5 macro program was utilized to determine the mediating effect of fear of disease progression on the relationship between metacognition and quality of life， and nonparametric Bootstrap with bias-correction was used to test the mediating effect. ResultsA total of 122 patients （90.37%） with ovarian cancer completed the effective questionnaire survey. Patients scored （90.52±17.13） on FACT-O， （68.52±16.31） on MCQ， and （37.72±8.91） on FoP-Q-SF. Pearson correlation analysis denoted that FoP-Q-SF score was negatively correlated with FACT-O score （r=-0.412， P<0.05） and positively correlated with MCQ score （r=0.241， P<0.05）， and MCQ score was negatively correlated with FACT-O score （r=-0.453， P<0.05）. Analysis demonstrated that the total effect of metacognition on quality of life was -0.298 （95% CI： -0.402~-0.186）. The direct effect of metacognition on quality of life was -0.219 （95% CI： -0.504~-0.277）， accounting for 73.49% of the total effect， and the indirect effect of metacognition on quality of life via fear of disease progression was -0.079 （95% CI： -0.162~-0.037）， accounting for 26.51% of the total effect. ConclusionQuality of life is reduced in patients with ovarian cancer， and fear of disease progression plays a partial mediating role in the relationship between metacognition and quality of life.

AIM: To explore the value of the corneal/refractive analyzer OPD-Scan III in assessing visual quality after Nd:YAG laser surgery in patients with posterior capsular opacification.METHODS: A total of 98 patients(98 eyes)with posterior capsular opacification who underwent Nd:YAG laser posterior capsulotomy in our hospital from May 2021 to April 2023 were retrospectively selected as the research subjects, and higher-order aberration parameters(coma, spherical aberration and trefoil aberration)and visual quality parameters [Strehl ratio(SR)and 4 mm area ratio(AR)in the human eye modulation transfer function(MTF)curve] were obtained using the corneal/refractive analyzer OPD-Scan III. The patient's visual acuity, higher-order aberration parameters and visual quality before surgery, and at 1 wk and 3 mo after surgery were compared.RESULTS: There were statistically significant differences in uncorrected distance visual acuity(UDVA), uncorrected intermediate visual acuity(UIVA)and uncorrected near visual acuity(UNVA), coma, spherical aberration, trefoil aberration, SR and AR before and after surgery(all P<0.001), and there were statistically significant differences in UDVA, UIVA, UNVA, coma, spherical aberration, trefoil aberration, SR and AR at 1 wk and 3 mo postoperatively(all P<0.05). Additionally, there were differences in the UDVA, UIVA, UNVA, SR and AR at 3 mo postoperatively compared with those parameters at 1 wk postoperatively(all P<0.05), while there were no statistical significance in coma, spherical aberration, trefoil aberration at 3 mo postoperatively and those at 1 wk postoperatively(all P>0.05). Furthermore, the spherical aberration, trefoil aberration were negatively correlated with SR(rs=-0.427, P=0.009; rs=-0.436, P=0.010), and the trefoil aberration was negatively correlated with AR(rs=-0.406, P=0.015).CONCLUSION: The visual acuity of patients with posterior capsular opacification improved after Nd:YAG laser surgery, and the corneal/refractive analyzer OPD-Scan III system has a high clinical value in reflecting patient's visual quality.
