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 construct an index system for including ideological and political education elements and cases in the Health Assessment course, and to provide a reference for the evaluation of ideological and political teaching of the Health Assessment course.Methods:By using literature analysis, the nominal group method, and the Delphi expert consultation method, we determined indicators for ideological and political elements and case inclusion criteria for the undergraduate nursing course Health Assessment. The analytic hierarchy method was applied to quantify the items and determine the final weights of the indicators at each level.Results:The response rates of two rounds of expert consultation were both 100%. The authority coefficient of the experts was 0.880. For the second-round consultation on the system of ideological and political elements, the coefficient of variation was 0.078, and the Kendall's coefficient of concordance was 0.334. For the second-round consultation on the inclusion criteria for ideological and political cases, the coefficient of variation was 0.075, and the Kendall's coefficient of concordance was 0.312. Finally, we determined 6 first-level indicators and 30 second-level indicators for the ideological and political elements of the Health Assessment course, and 9 indicators for the inclusion of ideological and political cases for the Health Assessment course.Conclusions:The established index system for the ideological and political elements and cases of the Health Assessment course for nursing undergraduates is reasonable, scientific, and reliable, which can provide a reference for subsequent construction of the ideological and political teaching system for the Health Assessment course.
