Sonodynamic therapy in many treatment methods of tumors, is a relatively new approach. Sonodynamic therapy as a treatment method is developed on the basis of photodynamic therapy. Compared to the lightwave, the ability to penetrate mammalian tissue of ultrasound is stronger. So sonodynamic therapy is a more promising therapeutic area. Many scholars have explored the clinical applications of sonodynamic therapy, and progress has been made in many areas. Because the female genitalia is connected the outside of body, it is more conducive that Sonodynamic therapy play a partial role. Sonodynamic therapy has some progress in the application of gynecology, and we hope it would have more progress in the treatment of endometrial disease.

Objective To investigate the accuracy of computer-assisted interpretation(CAI)in the diagnosis of pediatric critical arrhythmia,and to establish Logistic regression model to evaluate the main risk factors of CAI error.Methods 1147 cases of arrhythmia patients were divided into heart disease(HD)and nonheart disease group(NHD).Candidate risk factors were chosen,from which the vailables statistically significant were entered for logistic regression analysis.Results CAI error rate of HD group and NHD group were 24.9%and 11.4%,showing a significant difference(P＜0.05).Age,underlying diseases,the number of CAI diagnosis entries were the risk factors.Conclusion CAI error pattern was different among HD group and the NHD group.Higher awareness for CAI error risk factors and CAI technology improvement are critical for a lower CAI error rate.

Formation of dermal collagen fiber is a complicated and sequential process with the progressive assembly of collagen. Collagen monomers form stepped and orderly protofibrils through longitudinal displacement. Subsequently, protofibrils or protofibrils and collagen are bonded by covalent bonds to form orderly lamellar structure of collagen fibers. Then collagen fibers are tightly wound into coarse collagen fiber bundles by covalent crosslinking. Decorin is a multifunctional small leucine-rich proteoglycan. It can prevent the aggregation of protofibrils by binding to the specific site of collagen with its core protein, and adjusting the spacing between the protofibrils with its glycosaminoglycan chain. Thus, by effecting the formation of collagen fibers with regulation of collagen assembly, decorin may help prevent scar formation and even promote regeneration.

OBJECTIVEThis study aimed to investigate the duration of gingival healing after the stage II surgery of dental implantation for periodontitis patients and to provide clinical guidelines for implant restoration.

METHODSTwenty-nine periodontitis patients who had implantation surgery and achieved osseointegration were operated with stage II surgery (a total of 60 pieces of implants). The height of buccal gingival of each implant was measured twice after the stage II surgery. All implants were measured at the lowest point ofbuccal gingival after one week. The implants were randomly divided into four groups according to the schedule of the next test time: group one at one week from the initial test point, group two at two weeks, group three at three weeks, and group four at four weeks. Each group includes 15 pieces of implants. The amount of the buccal gingival change in each group between the second and first tests was determined, and the data were analyzed statistically.

RESULTSThe amount of gingival change of groups one, two, three, and four was (-0.25 +/- 0.66), (-0.04 +/- 0.52), (-0.70 +/- 0.77), and (-0.74 +/- 1.09) mm, respectively. No significant difference was observed between groups one and two in terms of the amount of gingival changes (P > 0.05). However, a significant difference was found between groups two and three (P < 0.05), and the amount of gingival recession was 0.66 mm. No significant difference was found between groups three and four (P > 0.05), and the gingival achieved stability.

CONCLUSIONThe gingival recession achieves stability at the fourth week (after 28 d) after stage II surgery. At this time, the implant can be restored, and the abutment can be selected according to the amount of gingival change of the periodontitis patient.

Objective To investigate the association between the lumbar vertebral fracture damage degree with the fracture classification,injury score,kyphosis deformity and nerve function injury.Methods According to the damage degree of posterior lig ament complex(PLC),the patients were divided into the PLC intact group and PLC injury group.Its relationship with PLC injury was researched by evaluating the fracture classification,injury score and nerve function injury situation in the two groups.Results The LCS score and TLICS score in the PLC injury group were (7.1±0.8) points and (8.2±0.6) points,which were higher than (5.7±0.5) points and (4.6±0.7) points in the PLC intact group.The Denis score in the PLC injury group was more serious.The Cobb angle in the PLC injury group was 29°,and which in the PLC intact group was 19°.The proportion of nerve function insufficiency in the PLC injury group was 89％,while which in the PLC intact group was only 60 ％.Conclusion The thoracolumbar vertebral fracture is closely related with PLC.PLC damage degree is positively correlated with the fracture classification,injury score,kyphosis deformity and nerve function injury degree.

Objective　To observe the changes of serum soluble interleukin-6 receptor (sIL-6R) and soluble gp130 (sgp130) in patients with pregnancy induced hypertension. Methods　Enzyme linked immunosorbent assay (ELISA) was used to determine serum sIL-6R and sgp130 levels in 40 patients with pregnancy induced hypertension (study group), 20 normal non-pregnant women (control group I) and 20 normal pregnant women (control group II). Results　In study group, sIL-6R was (196.7±12.9) μg/L and sgp130 was (379.4±79.3) μg/L. In control group I, sIL-6R was (174.8±46.2) μg/L and sgp130 was (273.6±28.3) μg/L. In control group II, sIL-6R was (174.4±48.3) μg/L and sgp130 was (254.4±34.7) μg/L. SIL-6R and sgp 130 were higher in study group than those in control groups with significant difference (P<0.01). In study group, the more severe the patients, the higher the sIL-6R and sgp130 levels. There was significant difference (P<0.01). There was no difference in sIL-6R and sgp130 levels between control groups (P>0.05). Conclusions Serum sIL-6R and sgp130 levels are related to the development of pregnancy induced hypertension.

Objective:To investigate the clinical effects of health and safety management in elderly patients receiving gastroenteroscopy under sedation.Methods:From February 2018 to November 2019, 126 elderly patients admitted to the cadre medicine and gerontology department of our hospital to undergo gastroenteroscopy under sedation were included as research subjects.According to the digital random number method, they were divided into the control group and the test group(n=63, each group). The control group was given routine management, while the test group was given routine management plus health and safety management.Clinical effects and safety were analyzed and compared between the two groups.Results:There was no significant difference in scores of the Hamilton anxiety scale(HAMA)and the Hamilton depression scale(HAMD)between the two groups before intervention.After intervention, the scores of HAMA and HAMD were lower in the test group than in the control group[(39.2±3.1)scores vs.(48.6±2.1)scores, (40.1±4.1)scores vs.(52.6±5.5)scores, t=19.926 and 14.463, both P=0.000]. The incidence of postoperative complications was lower in the test group than in the control group(7.94% or 5/63 vs.19.05% or 12/65, χ2=14.209, P=0.002). The differences between maximum and minimum values of heart rate(HR), diastolic blood pressure(DBP), respiratory rate(RR)and systolic blood pressure(SBP)were lower in the test group than in the control group(all P<0.05). The length of the procedure was shorter and the anesthetic dose was lower in the test group than in the control group(9.11±2.56 min vs.13.56±3.05 min, 15.35±2.66 ml vs.21.67±6.15 ml, t=8.870 and 7.486, both P=0.000). Patient satisfaction was higher in the test group than in the control group( χ2=16.383, P=0.014). Conclusions:Health and safety management can improve emotional health, stabilize vital signs and enhance satisfaction in elderly patients undergoing gastroenteroscopy under sedation.

Objective To investigate the effect of EGB on SOD, MDA of ventilator-induced lung injury in rats and its possible mechanisms. Methods Thirty male SD rats were randomly divided into 3 groups: control group (C group), high tidal ventilation group (H group) and EGB group (E group). The setting mechanical ventilation was VT=30 mL/kg, RR=40/min, I/E=1/3, PEEP=0 cmH2 O and FiO2=21%. The broncho-alveolar lavage fluid (BLAF) and serum were obtained for determination of the levels of SOD and MDA at the end of 4 h mechanical ventilation. The Lungs were removed, and the wet-to-dry weight ratio (W/D) and pulmonary pathologic changes were measured. Results As compared with C group, W/D and the levels of MDA were significantly increased in H group, but the levels of SOD were reduced in H group. As compared with H group, W/D and the levels of MDA were significantly decreased in E group, but the levels of SOD were increased in E group. Pulmonary pathologic changes were alleviated in E group comparing with H group. Conclusion EGB injection may have a protective role against hyperoxia and induced pulmonary damage in rats.

Objective To investigate the level and impact factors of stigma in people living with stroke patients in community. Methods A total of 189 stroke patients in community were investigated by general information questionnaire, Stigma Scale for Chronic Illness, Medical Moping Questionnaire, Self-Rating Depression Scale and Social Support Rating Scale. Results The total score of stigma was (44.96± 16.71) points, score of self-stigma was (27.70±10.91) points, score of enacted-stigma was (17.26±7.00) points. Multiple regression analysis showed that stroke patients′ depression, avoiding coping, subjective support and activity of daily living were impact factors of stigma, which explained 57.5% of the variance. Conclusions Community nurses should pay attention to the stigma of stroke patients in community, especially focus on those with higher degree of depression and lower activity of daily living, guiding them to adopt positive coping strategies and enhance subjective support. Oriented by influencing factors, proper intervention should be provided to lower the level of stigma, promote psychosomatic rehabilitation.

Objective To discuss the changes of plasma TXA2 and PGI2 levels in the rabbit model of pulmonary hypertension (PHA)induced by monocrotaline (MCT)when transplanted with endothelial progenitor cells (EPCs). Methods The rabbit pulmonary hypertension model was constructed by MCT induction. Rabbit endothelial progenitor cells were induced,separated and identified in vitro.50 New Zealand white rabbits were randomly divided into 3 groups,normal control group and model group were given M199 culture medium by tail vein injection,EPCs treatment group were given EPCs marked with fluorescent though tail vein injection. The levels of plasma TXB2 and 6-keto-PGF1αwere detected and their ratio were calculated after three weeks. Results Compared with model group,the content of 6-keto-PGFlαin plasma in EPCs group was (130.67 ±17.54)u mol/L,which was increased sinnificantly. The content of TXB2 was (402.89 ±27.98 )u mol/L,which was decreased significantly.The ratio of TXB2 to 6-keto-PGF1 alpha between two groups was statistically significant(P<0.01 ). Conclusion EPCs transplantation can reduce the content of TXA2 and increase the content of PGI2 in the pulmonary hypertension rabbits induced by monocrotaline,then reverse the damage of pulmonary hypertension.
