Objective To observe the clinical efficacy of hydrochloride minocycline ointment in the treatment of chronic periodontitis. Methods 40 patients( 100 teeth) with chronic periodontitis were divided into iodine glycerin group (control group)and hydrochloride minocycline ointment group (observation group). Before and after treatment, the changes of the periodontal depth, plaque index, tooth mobility, tooth week attachment level, gingival sulcus bleeding index were recorded and analyzed. Results There was no significant difference between the two groups before treatment (P > 0.05 ), and after treatment, the difference in every excerpt -time was significant (all P <0.05). Conclusion The treatment of hydrochloride minocycline ointment in chronic periodontitis was better than iodine glycerin, and could significantly improve the efficacy.

In this paper the four indexes of two mussels-Mytilus edulis and Mytilus coruscus were measured. The four indexes were protein, amino acids,unsaturated fatty acids and inorganic elements. The contents of protein and crude fats in Mytilus coruscus were higher than those in Mytilus edulis. The contents of essential amino acids have no difference between the two mussels. Mytilus coruscus is a heavy seafood,as there are much more glutamic acid, glycine and aspartic acid in it. The content of docosahexenoic acid (DHA)in M. coruscus was much more than that of M. edulis. Except for Aluminium and Selenium,the other 12 kinds of elements in M. edulis were higher than those in M. coruscus. The contents of polyunsatu-rated fatty acids(PUFAs) were much more than those of monounsaturated acids (MUFAs)in M. coruscus. There is little difference of the content between PUFAs and MUFAs in M. edulis.

Amphetamine-type stimulants ( ATS ) , a group of new-type synthetic drugs mainly in psychological dependence, are abused more and more severely in recent years. MicroRNAs ( MiRNAs ) are an important class of endogenous non-coding small RNAs that mediate posttranscriptional negatively regulation of gene expression by targeting specific mRNA sequences to in-hibit the translation of mRNAs or degrade the expression of mR-NAs. ATS can induce the changes in the expression of miRNAs in addiction-related brain regions which directly involve in the regulation of ATS-induced addictive behaviors. Therefore, to study the regulatory role of miRNAs in ATS-induced addiction has important implications for dependent mechanisms of new-type drugs and the discovery of the new targets of drug actions.

Objective To explore the clinical efficacy of the interventional recanalization for infertile women with fallopian tube obstruction. Methods 636 infertile patients with fallopian tube obstruction diagnosed by hystero-salpin-gngraphy were treated with interventional tubal recanalizafion under X-ray.

Objective To investigate the risk factors of cognitive impairment in post-intensive care syndrome patient (PICS-CI).Methods A retrospective study was conducted. The patient who transferred from post-intensive care unit (ICU) to the general ward for more than 7 days, and with the age ≥ 18 years old in the First Affiliated Hospital of Jinzhou Medical University from October 2015 to November 2016 were enrolled. The gender, age, marital status, education, occupation, salary, economic income, smoking, alcohol drinking, previous of history, mechanical ventilation, the length of ICU stay, sedative and delirium, and initial diagnosis were recorded. According to mini-mental state examination (MMSE), the patients were divided into cognitive impairment (CI) group and non-CI group. Univariate analysis was performed to identify the risk factors of PICS-CI, and variables with statistical difference were selected to do multivariate binary logistic regression analysis for the confirmable independence risk factors.Results 104 of the 290 patients developed CI, and the incidence was 35.86%. Univariate analysis showed that the gender, age, education, financial situation, smoking, alcohol drinking, previous of history, mechanical ventilation, the length of ICU stay, sedative and delirium, and initial diagnosis were recorded of ICU were main predictors of PICS-CI patients. It was shown by multivariate binary logistic regression analysis that the age > 60 years old [odds ratio (OR) = 7.523, 95% confidence interval (95%CI) = 2.572-37.851,P = 0.001], mechanical ventilation (OR = 8.773, 95%CI = 2.588-36.344,P < 0.001), sedation (OR = 9.376, 95%CI = 2.661-42.011,P = 0.002), and delirium (OR = 13.201, 95%CI = 2.502-41.433, P < 0.001) were PICS-CI independence risk factors.Conclusions Nurse staffs should strength care and attention on ICU transferred out patients. In order to minimize PICS impairment, special precaution should be implemented according to different aspects.

Objective To observe the curative effect and adverse reactions of IMRT and conventional radiotherapy combined with chem-otherapy in treating patients with advanced nasopharyngeal carcinoma. Methods The patients were divided into the IMRT group (46 cases) and conventional radiotherapy combined with chemotherapy group ( 50 cases ) . Making the IMRT and conventional radiotherapy combined with chemotherapy treatment plan, and analyze the curative effect and adverse reaction of the two groups. Results Compared with the con-ventional radiotherapy combined with chemotherapy group, IMRT group has a significantly increase in complete remission rate and overall re-sponse rate, but there is no significant difference in long-term efficacy. The skin, dry mouth ( parotid) ,and oral mucositis response is lower in IMRT group, and the neutropenia incidence, prevalence of anemia, liver and kidney function damage rate is also significantly lower than conventional radiotherapy combined with chemotherapy. Conclusion The IMRT can significantly improve the curative effect in treatment of advanced nasopharyngeal carcinoma and reduce the adverse reactions compared with the conventional radiotherapy combined with chemotherapy.

Objective To study the effect o f levamisole against the invasion of Schistosoma japonicum cercariae. Methods Mice infected wit h Schistosoma cercariae were administered orally with levamisole hydrochloride or alkali levamisole two days before the infectio n at a dose of 26.25 mg/kg for 7 days. The liniments of levamisole hydrochlorid e and alkali levamisole were embrocated on the mouse skin two days, one day and 0 day before the infection respectively, and the concentrations of the drug were 1%, 2%, 3%, 5% and 7% respectively. The experimental animals were dissected 4 we eks after the treatment and adult worms were collected. Results The worm reduction rates of mice administered orally with leva misole hydrochloride or alkali levamisole were both 0. The worm reduction rates were both 100% when the mice were embrocated with 5% levamisole hydrochloride on the infection day or with 7% levamisole hydrochloride one day before the infect ion. The worm reduction rates were all 100% when the mice were embrocated with 2 %, 3% or 5% alkali levamisole one day before the infection. Conc lusions Levamisole liniments can prevent from S . japonicum cercaria infection, and alkali levamisole is better th an levamisole hydrochloride.

Objective: To investigate the burden of caregivers of elderly patients with chronic diseases and its influencing factors, so as to provide the evidence for reducing the burden of caregivers. Methods: The caregivers of patients with chronic diseases at ages of 65 years and older were selected using convenience sampling method from Jinqiu Hospital during 2020 and 2021. The burden of caregivers was estimated using Chinese version of Caregiver Burden Scale (CBI), the basic information of patients and caregivers was collected, and the influencing factors of caregivers' burden were identified using multivariable linear regression analysis. Results: Totally 276 questionnaires were distributed, and 261 were valid, with an effective rate of 94.57%. There were 48 men (18.39%) and 213 women (81.16%), 166 (63.60%) subjects aged 45 to 59 years and 354 (82.38%) subjects participating in training on COVID-19 prevention. The mean score of caregivers' burden was 26.27±14.93, and the mean scores of social burden and emotional burden were 11.08±5.23 and 7.81±6.24, respectively. The patients with chronic diseases included 183 men (70.11%), had a mean age of (89.97±8.26) years, had a mean score of activities of daily living of 20.00 (interquartile range, 50.00) and had a mean geriatric syndrome number of 4.10±1.57. Multivariable linear regression analysis identified caregivers' participating in training on COVID-19 prevention (β'=0.175), patients' activities of daily living (β'=-0.144), patients' geriatric syndrome number (β'=0.138) and patients' age (β'=0.162) as factors affecting the burden of caregivers. Conclusions The social and mental burden of the caregivers of elderly patients with chronic diseases is heavy, and patients' activities of daily living, number of geriatric syndromes and age, as well as caregivers' training on COVID-19 prevention may be associated.
