AIM: To analyze the efficacy of bevel-up phaco chop versus bevel-down phaco drill in the treatment of hard nuclear cataract and the influence on corneal endothelium.

METHODS: Between August 2018 and April 2020, 94 patients(104 eyes)with hard(grade Ⅳ-Ⅴ)nuclear cataract treated with phacoemulsification were enrolled in this retrospective study. Among them, 50 eyes treated by bevel-up phaco chop were included in the control group, while 54 eyes treated by phaco drill technique were included in the observation group. The time of using ultrasound, ultrasonic energy and accumulated energy complex parameter in the two groups were recorded. The best corrected visual acuity(BCVA)in 7d, corneal endothelial cell count in 2mo, the proportions of normal hexagonal cells and the degree of corneal edema in 7d were compared between the two groups.

RESULTS: The time of using ultrasound, ultrasonic energy and accumulated energy complex parameter of the observation group were shorter and lower than those of the control group(P<0.05). The BCVA of both groups increased after operation, and the observation group had higher BCVA than the control group at the same time(P<0.05). In 1 and 2mo, the corneal endothelial cell counts and the proportions of normal hexagonal cells in both groups were lower than those before operation. Meanwhile, the corneal endothelial cell count and the proportions of normal hexagonal cells in the observation group were higher than those in the control group(P<0.05). Besides, corneal edema was milder in the observation group than in the control group at 24h and 7d after operation(P<0.05).

CONCLUSION: Compared with bevel-up phaco chop, phaco drill can significantly shorten the time of using ultrasound, reduce ultrasound energy, promote visual recovery, and reduce corneal endothelial cell damage.

Objective To analyze the endemic situation of schistosomiasis in Jiangshan City from 2008 to 2018, so as to provide evidence for formulating the future control strategy. Methods The data regarding Oncomelania snail survey and control, schistosomiasis examinations and environmental improvements were collected in Jiangshan City from 2008 to 2018. The changes in snail status and morbidity due to Schistosoma japonicum infections were analyzed to assess the effectiveness of comprehensive schistosomiasis control. Results From 2008 to 2018, a total of 61 220 person-times were examined for S. japonicum infections in Jiangshan City, and the overall seroprevalence of S. japonicum infections was 0.56% (343/61 220); however, no egg-positives were detected. Among 4 231 cattle screened for S. japonicum infections using blood tests in Jiangshan City during the period from 2008 to 2018, 12 were sero-positive, with sero-prevalence of 0.28% (12/4 231), and no egg-positives were identified. There were 422 snail habitats identified in Jiangshan City during the study period, covering an area of 46.915 hm², and among the 31 686 snails dissected, no S. japonicum infections were detected. An area of 3 625.492 hm² snail habitats were subjected to repeated snail control and 11 settings were given environmental improvements, covering snail habitats of 17.880 hm² and historical snail habitats of 204.380 hm². Conclusions Following the implementation of environmental improvements-based comprehensive schistosomiasis control, the endemic situation of schistosomiasis is stable in Jiangshan City; however, there is still a risk of snail importation and re-emerging schistosomiasis. Therefore, the monitoring of snails and morbidity due to S. japonicum infections should be intensified in the city.

Sleep disorder is a common complication after is chemicstroke.If it is nottimely diagnosed and treated, it may affect the rehabilitation of stroke and recurrence. The manifestations of sleep disorders have various forms according to the different locations of infarction. For the treatment of sleep disorder after stroke, the method of the combination of drugs and physical therapy is used in clinical practice at present. In recent years, w ith the w idely use of the polysomnography, poststroke sleep disorders can be diagnosed clearly and carefuly. The treatment for sleep disorders after stroke may significantly improve the prognosis of patients.

Diabetes mellitus is an independent predictor of high platelet reactivity after antiplatelet therapy in patients with ischemic stroke,and the latter is closely related to the increased risk of recurrence of stroke.The mechanisms of high platelet reactivity in patients with diabetes or insulin resistance are associated with a variety of factors.Some circulating molecules can be used as markers for predicting the reactivity of platelets.Monitoring of platelet reactivity after treatment with new antiplatelet agents may provide basis for individualized antithrombotic therapy in ischemic stroke patients with diabetes or insulin resistance.

OBJECTIVETo compare the difference in the clinical efficacy on infantile food accumulation treated with centripetal tuina therapy at spleen meridian site of different location.

METHODSSixty cases of infantile food accumulation were randomized into a palmar thumb surface group and a radial margin group, 30 cases in each one. In the palmar thumb surface group, the spleen meridian was stimulated with the pushing technique centripetally on the palmar side of the thumb. In the radial margin group, the spleen meridian was stimulated with the pushing, technique centripetally along the radial margin of the thumb. The traditional tuina techniques, such as tuisanguan, yun neibagua were combined in the two groups. The treatment was given once a day, 6 times a week, 12 treatments as one session. After the 1 session of treatment, the main symptom scores before and after treatment were compared in the patients of the two groups, the improvements in the accompanied symptoms were observed, such as appetite, defecation and tongue coating; and the efficacy was evaluated in the two groups.

RESULTSThe total effective rates were 93.3% (28/30) and 90.0% (27/30) in the palmar thumb surface group and the radial margin group respectively and the difference was not significant statistically in comparison of the two groups (P > 0.05). After treatment, the main symptom score was improved significantly in the two groups, indicating the significant difference as compared with that before treatment (both P < 0.05). The improvement in foul breathing in the palmar thumb surface group was better than that in the radial margin group (P < 0.05).

CONCLUSIONBetween the two kinds of pushing techniques at spleen meridian site, pushing on the palmar surface of the thumb and pushing along the radial margin, there is no difference in the total efficacy on infantile food accumulation. Regarding the improvement in foul breathing, the effect in the palmar thumb surface group is better than that in the radial margin group.

Objective:To discuss the clinical efficacy of Liu’s infantile tuina therapy in treating kid’s allergic rhinitis (AR).
Methods:Sixty eligible AR kids were randomized into a tuina group and a Western medication group by their visiting sequence, 30 cases in each group. The tuina group was intervened by Liu’s infantile tuina therapy, once daily, 5 times as a treatment course, with a 2-day interval after a course; the control group was by orally taking Loratadine. The therapeutic efficacies were compared and analyzed after treatment for 4 successive weeks.
Results:After treatment, the symptoms such as itchy nose, sneezing, runny nose, and stuffy nose were significantly improved in both groups (P<0.05), and the improvements in the tuina group were more remarkable than those in the Western medication group (P<0.05). The total effective rate was 90.0% in the tuina group versus 73.3% in the Western medication group, and the difference was statistically significant (P<0.05).
Conclusion:Liu’s infantile tuina therapy can produce a better therapeutic efficacy in treating AR kids compared to oral administration of Loratadine.

Objective To observe the difference in the effect of chest compression quality between the traditional training (TT) and the standard video training (SVT). Methods A total of 197 graduate students were divided into two groups according to the different training methods: group A (traditional modality, n=98) and group B (video training modality, n=99). After training for 2 hours, all trainees were asked to practice CPR on a resuscitation manikin for 2 minutes under the monitoring of CPR quality by a feedback system with trainee's back towards compute monitor. The data of chest compression rate (times/min), average depth (cm) and chest compression release velocity (CCRV, mm/ s) were collected and analyzed. Results Compared with TT, the mean compression depth in SVT was (5.42 ± 0.07) cm vs. (5.33±0.08) cm; the effective rate of CPR in SVT was (115±1.034) /min vs. (113.6±1.152) times/min; the mean CCRV in SVT was (439.7±7.72) mm/s vs. (417.3±7.64) mm/s in the first minute (P＜0.05) and (403.9±7.22) vs. (384.5±8.48) mm/s in the second minute (P＞0.05). Conclusions There were no significant differences on improving the quality of CPR between the two groups. The video training showed no significant effectivity on improving the quality of CPR compared with the traditional way.

Objective:To evaluate the efficacy and safety of the combination of apatinib and S-1 for treatment of patients with advanced gastric cancer, in order to provide clinical therapy reference for advanced gastric cancer.Methods:Clinical trials were retrieved from China National Knowledge Infrastructure (CNKI) , Chinese Science and Technology Journal Database (CSTJ) , Wanfang Medical Network, VIP Journal Database (VIP) , China Biomedical Literature Database (CBMdisc) , Cochrane Library, PubMed, etc., searched from Jan. 2010 to Oct. 2019. The experimental group were given apatinib combined with S-1, and the control group received S-1 monotherapy. Two sets of RCT in patients with advanced gastric cancer were collected. Researchers first screened literature, data extraction and to assess the risk of bias, then made Meta analysis with RevMan5.3 software, the test level was α=0.05.Results:A total of 12 Meta analysis of randomized RCT were selected from the group, including 561 cases of patients. The results showed that objective response rate (ORR) and disease control rate (DCR) of the experimental group was higher than those of the control group [ (RD=0.16, 95% CI: 0.08-0.23, P<0.0001; RD=0.21,95% CI: 0.14-0.29, P<0.00001) ]; There was no significant difference in nausea and vomiting, hand-foot syndrome, fatigue, diarrhea, thrombocytopenia, neutropenia, leukopenia, neuro-toxicity and mucositis between the two groups. The rate of hypertension, proteinuria, hemoglobin of the experimental group decrease was higher than that of the control group [ (OR=6.21, 95% CI: 1.92-20.13, P=0.002; OR = 10.57,95% CI: 5.06-22.04, P<0.00001; OR=2.84, 95% CI:1.25-6.48, P=0.01) ]; and there was a significant heterogeneity in hypertension among them ( P=0.008, I 2=63) . Conclusion:Compared with S-1 alone, the treatment effect of S-1 combined with targeted drug apatinib can significantly improve ORR and DCR of patients with advanced gastric cancer.

Hydatid disease imposing serious threat on human health and great loss in livenotstock pastoralism remains a major public health problem in western China. To assess and monitor the effect of control program on transmission dynamics, we used the prevalence of cystic echinococcosis in slaughtered sheep at slaughterhouse as an indicator during the period of 2007 to 2013 in Emin County, Xinjiang Uygur Autonomous Region, China. The results showed a significant decline trend of prevalence in all age groups during the 7 years when the control program was implemented; particularly, the rate was reduced by 72% after first 3 years. Among the sheep slaughtered, the age distribution evidenced that the prevalence increased significantly as the sheep grew older. The baseline data indicated that the rate was 4.5% at the age <1, 6.7% at age 2~, and reached to the highest 17.9% at age > or =4 years. Earlier response to the intervention pressure was seen in the sheep at the younger age. Significant decline started from 2008 at the age <1, from 2009 at age of 1~, 2010 at 2~ to 3~, and the latest, in 2012 at age > or =4. This study demonstrated that the prevalence of cystic echinococcosis in slaughtered sheep may be used as an indicator to assess and monitor the transmission status during and after control program providing information for betterment of performance to sustain control strength.

Objective:To investigate the predictive value of platelet reactivity for early neurological deterioration (END) in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke within 48 h of onset admitted to the Department of Neurology, the Affiliated Haikou Hospital of Xiangya School of Medicine, Central South University from January 2017 to March 2019 were enrolled prospectively. Aspirin was taken on the day of admission, and the platelet aggregation rate was detected using a PL-11 Platelet Function Analyzer 7 d after taking it. END was defined as the National Institutes of Health Stroke Scale (NHISS) score at any time point within 7 d after admission increased by ≥2 or the motor function item score increased by ≥1 from baseline. The demographics, baseline data, imaging examination and laboratory findings of patients in the END and non-END groups were compared. Multivariate logistic regression analysis was used to determine the independent risk factors for END. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of platelet aggregation rate for END. Results:A total of 230 patients were included in the study. They aged 63.24±9.75 years, 126 were females (51.4%). The median baseline NIHSS score was 6 (interquartile range, 4-10). The median time from onset to admission was 15 h (interquartile range, 9-28 h). There were 54 patients (23.5%) in the END group and 176 (76.5%) in the non-END group. There were significant differences in arachidonic acid-induced maximum platelet aggregation ratio (MAR-AA), epinephrine-induced maximum platelet aggregation ratio (MAR-EPI) and collagen-induced maximum platelet aggregation ratio (MAR-COL) between the END group and the non-END group (all P<0.05). Multivariate logistic regression analysis showed that MAR-AA (odd ratio [ OR] 1.165, 95% confidence interval [ CI] 1.091-1.243; P<0.001) and MAR-EPI ( OR 1.035, 95% CI 1.006-1.067; P=0.023) were the independent risk factors for END in patients with acute ischemic stroke. ROC curve analysis showed that MAR-AA had good predictive value for END, and the area under the curve was 0.775 (95% CI 0.707-0.843; P<0.001). The optimal cut-off value was 21.80%. The sensitivity and specificity of MAR-AA for predicting END were 72.2% and 77.3%, respectively. Conclusions:The platelet function measured by PL-11 is closely related to the risk of END in patients with acute ischemic stroke. It has a better predictive value for END.
