Objective To examine the bactericidal effects of three different states of medical ozone (liquid, gas, and oil) against drug-resistant strains of common bacteria on burn wounds, which could as a clinical reference. Methods Three multidrug-resistant strains of methicillin-resistant Staphylococcus aureus , pan-resistant Pseudomonas aeruginosa , and ESBLs Klebsiella pneumoniae were identified from burn wounds. The colonies of the three varieties of bacteria were each carried out using the pour plate method prior to the start of the experiment. Then, depending on the state of ozone, different treatment procedures are applied. Group of ozone gas: in a closed glass jar, the bacterial liquid was injected into a single layer of sterile gauze, and the ozone gas concentration was held at 50 g/mL. The bacterial liquid was diluted and combined directly with ozone water in the ozone water group. Ozone is a type of oil: after the emulsifier was added to the oil group. The gas, water, and oil groups were rapidly neutralized and counted again after 5, 10, and 30 minutes. Results Ozone gas and oil groups totally eliminated multidrug resistant bacteria in the above study within 30 minutes. (2) At 5 and 10 minutes, the difference in bactericidal effect between ozone gas group and ozone water and oil group was statistically significant (P<0.05), and there was no significant difference between ozone water and oil groups (P>0.05); at the time of 30 minutes, the effects of bactericidal effect between ozone water group and ozone gas and oil had no significance (P> 0.05). Conclusion Ozone has the ability to kill bacteria, depending on the treatment time, different ozone types should be chosen for sterilization and disinfection in clinical application.

Background. Endocrine disorders such as amenorrhea, lactation, and irregular menstruation caused by antipsychotics are common in female patients. How to reduce or eliminate these adverse reactions is a matter of concern. Objective. To evaluate the therapeutic effect of progesterone in combination with vitamin B6 in the treatment of antipsychotic-induced amenorrhea. Methods. In our hospital, from May 2019 to May 2021, 120 patients with amenorrhea caused by antipsychotics who underwent surgery were selected for this prospective study. The random residue grouping method divided them into a progesterone group (60 cases) and a vitamin B6 group (60 cases). Among them, the progesterone group was treated only with progesterone, while the vitamin B6 group was given progesterone in combination with vitamin B6. The differences in endocrine index, prolactin, uterine size, and endometrial thickness, effectiveness, and safety analysis of the progesterone and vitamin B6 groups of patients were observed and compared. Results. Before treatment, there was no change in the comparison of endocrine indexes between the progesterone and vitamin B6 groups ( P > 0.05 ). After 1 month of treatment, there were significant differences in estradiol, prolactin, and follicle-stimulating hormone between the progesterone and vitamin B6 groups of patients ( P < 0.05 ). After 1 month of treatment, there were significant differences in prolactin, uterine size, and endometrial thickness, and the vitamin B6 group was significantly lower than the progesterone group ( P < 0.05 ). The clinical efficiency of 95.00% in the vitamin B6 group was significantly higher than 83.33% in the progesterone group ( P < 0.05 ). There were no adverse reactions in the progesterone and vitamin B6 groups. Conclusion. The effectiveness of progesterone combined with vitamin B6 in treating amenorrhea caused by antipsychotics is significantly better than simple progesterone, which can effectively improve the endocrine condition of patients and provide a reference for the clinical treatment of amenorrhea caused by antipsychotics.

Our study aimed to investigate the effects of computer-assisted cognitive remediation therapy (CCRT) on cognitive function, social function and quality of life in patients with vascular dementia (VD). Methods: Ninety-eight patients with VD were treated with CCRT in four 45-minute sessions per week over a course of 40 sessions to exercise four cognitive functions, including flexibility, working memory, plan execution and social cognition. The Mini-Mental State Examination (MMSE), Social Disability Screening Schedule (SDSS), Personal and Social Performance Scale (PSP), and Generic Quality of Life Inventory-74 (GQOL-74) were used to assess before and after treatment. Results: (1) The scores of orientation (5.60 ± 1.35), calculation (2.20 ± 0.79), verbal ability (7.10 ± 0.36), spatial ability (0.78 ± 0.42), immediate memory (2.42 ± 0.53), short-term memory (1.17 ± 0.78) and MMSE (23.36 ± 2.98) were all improved after treatment (P < 0.05) compared with those before treatment; (2) The scores of SDSS,
