Objective:To introduce a self-made film holder for standardized alignment of intraoral film and to evaluate its validity.Methods:The film holder,consisting of film backing,bite block and indicating part,was made of a kind of transparent material.20 patients were photographed using the film holder for serial dental films and another 20 patients were photographed using conventional bitewing instrument.The distance between the cemento-enamel junction and alveolar crest and the distance between cemento-enamel junction of adjacent teeth were measured on the serial films taken in the two groups.Results:The films taken by the use of film holder showed greater reproducibility than those by bitewing.Variables changes were significant smaller in film holder group than those in bitewing group.Conclusion:The film holder can be used as a instrument for standardized alignment of intraoral film.

Objective:To investigate the effect of Internet plus rehabilitation nursing service and continual nursing on postoperative rehabilitation of patients with osteoporotic lumbar compression fracture (OLCF).Methods:A retrospective case-control study was conducted to analyze the clinical data of 123 patients with OLCF admitted to Affiliated Hospital of Henan Medical College from May 2018 to October 2019. There were 46 males and 77 females, aged 56-74 years [(65.3±5.4)years]. The level of injury was located at L 1 in 93 patients, L 2 in 19, L 3 in 10, and L 4 in 1. The Denis fracture classification was type A in 26 patients, type B in 30, type C in 27, and type D in 40. All patients were treated by percutaneous kyphoplasty (PKP). A total of 62 patients were given Internet plus rehabilitation care services and continual care guidance (Group A), and 61 patients were given routine care health education before discharge (Group B). The Japanese orthopaedic association (JOA) score, visual analoge score (VAS), osteoporosis health confidence scale (OHBS) score, and adult health self-management ability assessment scale (AHSMSRS) score were recorded before and after intervention. The self-made questionnaires and Newcastle nursing service satisfaction scale (NSNS) were used to evaluate the compliance rate and nursing satisfaction after 3 months of intervention. Results:All patients were followed up for 3-6 months [(4.5±1.2)months]. In Group A, the JOA score was (12.1±2.1)points before intervention and (23.0±1.1)points after 3 months of intervention; the VAS was (4.4±1.3)points before intervention and (1.5±0.6)points after 3 months of intervention; the OHBS score was (81.4±4.0)points before intervention and (121.6±9.7)points after 3 months of intervention; the AHSMSRS score was (96.3±3.5)points before intervention and (143.5±11.0)points after 3 months of intervention. In Group B, the JOA score was (12.3±2.1)points before intervention and (20.4±1.2)points after 3 months of intervention; the VAS was (4.2±1.4)points before intervention and (3.6±1.1)points after 3 months of intervention; the OHBS score was (82.1±3.7)points before intervention and (108.7±9.4)points after 3 months of intervention; the AHSMSRS score was (97.1±3.8)points before intervention and (127.7±9.9)points after 3 months of intervention. The JOA score, VAS, OHBS score and AHSMSRS score in both groups were significantly improved after intervention ( P<0.01). These scores in Group A were higher than those in Group B after 3 months of intervention ( P< 0.01). The compliance rate and nursing satisfaction in Group A were 90% (56/62) and 94% (58/62) after 3 months of intervention, while those in Group B were 74% (45/61) and 75% (46/61) ( P<0.05 or 0.01). Conclusion:Compared with conventional nursing, Internet plus rehabilitation nursing service and continual nursing for OLCF patients can promote the postoperative lumbar functional recovery, reduce pain, improve self-management ability and compliance behavior, and enhance the recognition of nursing service, which is worthy of clinical application.

Objective:To explore the mediating effect of self-advocacy between posttraumatic growth and social isolation among female breast cancer survivors, so as to provide reference for the establishing nursing intervention strategies for social isolation.Methods:A random samplingsurvey was conducted, a total of 220 female breast cancer survivors from May to December 2021in Tianjin Cancer Hospital Airport Hospital were recruited by convenience sampling method. They were investigated by the general information questionnaire, General Alienation Scale, Posttraumatic Growth Inventory and Female Self-advocacy in Cancer Survivorship, respectively.Results:A total of 203 valid questionnaires were collected. The score of posttraumatic growth was (60.91 ± 12.04) points, self-advocacy was (59.56 ± 12.19) points, social isolation was (36.52 ± 7.79) points of female breast cancer survivors. The Posttraumatic Growth Inventory scores of each dimension in female breast cancer survivors were positively correlated with the scores of female self-advocacy of each dimension in cancer survivorship ( r values were 0.219-0.686, all P<0.01); each dimension of the General Alienation Scale scores were negatively correlated with the scores of Posttraumatic Growth Inventory and Female Self-advocacy in Breast Cancer Survivorship ( r values were -0.804 to -0.202, all P<0.01). The posttraumatic growth of female breast cancer survivors affected social alienation through self-advocacy, which showed the mediating effect of self-advocacy accounts for 32.8% of total effect. Conclusions:Self-advocacy plays a mediating role in the relationship between posttraumatic growth and social isolation. Nurses can improve the level of self-advocacy of female breast cancer survivors and promote posttraumatic growth, so as to decrease social isolation.

OBJECTIVE: To investigate the change trends of sperm quality with seasonal variations among the volunteers of sperm donors in Beijing area, as well as the relationship between two parameters. METHODS: Semen data from the volunteers of sperm donors in Human Sperm Bank of Peking University Third Hospital were collected using a retrospective study method. The subjects were divided into 4 seasonal groups based on the lunar solar terms and the time of sperm donation. The data were assessed to find whether there were differences in semen parameters among different seasonal groups, and to analyze the change trends and the influence of seasonal factors on semen parameters. RESULTS: A total of 21 174 semen parameter data were analyzed. Firstly, to analyze all data as a whole, in spring, summer, autumn and winter groups, sperm concentration was (106.04±59.67)×10⁶/mL, (97.61±47.41)×10⁶/mL, (100.18±47.17)×10⁶/mL, (100.59±38.68)×10⁶/mL, respectively, and the spring group was significantly higher than the other 3 seasonal groups (P < 0.001); proportion of progressive motility sperm (PR) was 56.49%±12.76%, 58.02%±13.65%, 58.05%±12.36%, and 57.66%±12.61%, respectively, spring group was lower than the other three seasonal groups, and summer group was better among the latter (P < 0.001). There was no difference in normal rate of sperm morphology among the four seasonal groups. The qualified rate of sperm donors in the winter group was higher than that in the other three seasons groups (P < 0.01), while the qualified rate in the summer group was lower than that in the other three seasons groups. In addition, the semen parameters of the volunteers during the screening period and the official sperm donation period were analyzed respectively, which revealed that sperm concentration of spring group was higher than that of summer and winter groups, and PR was lower than that of summer and autumn groups. On account of the semen parameters of official sperm donation period, multiple linear regression analysis found that season was the main factor affecting sperm concentration, the average sperm concentration in spring group was about 6×10⁶/mL higher than in winter group, but PR was 2.9% lower in spring group compared with autumn group (all P < 0.05). CONCLUSION Season was the influencing factor of semen quality of sperm donors in Beijing area. We recommend spring and winter may be the preferred seasons for sperm donation.
