Objective : To identify the factors affecting the adherence to administration of nucleoside/nucleotide analogues among patients with chronic hepatitis B (CHB), so as to provide insights into improving medication adherence among CHB patients. Methods: CHB patients at ages of 18 to 44 years that underwent treatment in Hangzhou First People's Hospital Affiliated to Zhejiang University School of Medicine from June 2021 to December 2022 were enrolled, and subjects' demographic and clinical characteristics were collected. The medication adherence was evaluated with the Morisky Medication Adherence Scale, and the negative illness perception was evaluated using the simplified Illness Perception Questionnaire, while the social support level was evaluated with the Social Support Scale. In addition, factors affecting the medical adherence were identified using a multivariable logistic regression model among CHB patients. Results: A total of 225 questionnaires were allocated and 210 valid questionnaires were recovered, with an effective recovery rate of 93.33%. The respondents had a mean age of (35.94±8.72) years, and included 119 men (56.67%) and 91 women (43.33%), with a mean total illness perception score of (44.09±12.06) points. Morisky Medication Adherence Scale classified good in 149 cases (70.95%) and poor in 61 cases (29.05%). Multivariable logistic regression analysis identified an educational level of college degree and above (OR=1.676, 95%CI: 1.105-2.910), family monthly per capita income of >5 000 Yuan (OR=2.518, 95%CI: 1.360-5.033), receiving health education pertaining to CHB (OR=3.590, 95%CI: 1.611- 7.932), high or medium level of social support (high: OR=3.202, 95%CI: 1.613-5.870; medium: OR=1.267, 95%CI: 1.085-2.409) as factors improving the medication adherence, and administration of more than 3 types of drugs (OR=0.388, 95%CI: 0.204-0.526) and high illness perception score (OR=0.601, 95%CI: 0.395-0.808) as factors constraining medication adherence among CHB patients. Conclusions The medication adherence are affected by educational level, family monthly per capita income, types of drugs, illness perception score, health education pertaining to CHB and social support level among CHB patients. Individualized intervention strategy is required targeting these influencing factors to improve the medication adherence among CHB patients.

Objective To explore the technique and clinical outcome of the atlantoaxial pedicle screw system in the treatment of the unstable atlantoaxial dislocation post traction.Methods The study involved 32 patients with atlantoaxial dislocation(type T2 of TOI classification)admitted from March 2005 to September 2009.There were 17 patients with fresh odontoid fracture and two with old odontoid fracture,five with traumatic disruption of the transverse atlantal ligament and eight with congenital odontoid dysplasia.JOA scores of neurological function before operation was at a range of 5-13(average 8.38).The average of space available for the cord(SAC)was 9.15 mm.Before the atlantoaxial pedicle screw system was carried out,the skull traction was performed in all the patients preoperatively.Results A total of 128 pedicle screws were inserted safely,with mean operation time and perioperative blood loss for 1.5 hours and 300 ml,respectively.No injury to the vertebral artery or spinal cord was observed.All the patients were followed up for 12-24 months,which showed that JOA scores one year after operation was increased to 10-17(average 14.56),with the improvement rate of 71.70%,and that the SAC was average 14.86 mm.The X-ray and SCT scans verified the proper position of the screws,with no internal fixation failure or atlantoaxial redislocation.After 3-6 months,all the patients except for one patient achieved a solid bone fusion.One year after operation,the one patient with no bone graft fusion was removed of the internal fixation system and obtained satisfactory restoration of the rotational function.Conclusions Atlantoaxial pedicle screw system is an effective method for the treatment of the unstable atlantoaxial dislocation post traction,for it has the advantages of stable three-dimension fixation,direct screw placement,intraoperative reduction and high fusion rate.

Objective: To investigate the perception about illness and identify its influencing factors among patients with non-alcoholic fatty liver disease ( NAFLD ) , so as to provide insights into the management of NAFLD patients. Methods: NAFLD patients admitted to Hangzhou First People's Hospital Affiliated to Medical School of Zhejiang University from January to June, 2020, were selected as the study subjects, and subjects' demographic features were collected using questionnaires, including gender, age and education level. The perception about illness, coping models and social support were assessed using the Brief Illness Perception Questionnaire (BIPQ), Medical Coping Modes Questionnaire ( MCMQ ) and Social Support Rating Scale ( SSRS ), respectively, and factors affecting the perception about illness were identified using multivariable linear regression analysis among NAFLD patients. Results: The 286 respondents included 151 males ( 52.80% ) and 135 females ( 47.20% ), and had a mean age of ( 55.27±10.39 ) years. The mean illness perception score was 38.55±9.21 among the respondents. The mean SSRS score was 42.90±8.64. The mean coping mode scores of confronce, avoidance and resignation were 23.51±4.30, 17.49±2.82, and 7.12±2.05, respectively. Multivariable linear regression analysis identified education level ( high school, β'=-0.216; diploma and above, β'=-0.355 ), household monthly income per capita ( β'=-0.372 ), regular exercise ( β'=-0.310 ), coping modes ( confronce, β'=-0.326; avoidance, β'=-0.191 ) and social support level ( β'=-0.259 ) as factors affecting the perception about illness among NAFLD patients. Conclusion Negative perceptions about illness are found among NAFLD patients, and household income, education level, regular exercise and coping modes are factors affecting the illness perception among NAFLD patients.

Objective:To evaluate the efficiency of using artificial intelligence reading label system in diabetic retinopathy (DR) grading training among junior ophthalmologists and medical students.Methods:520 diabetic fundus images were randomly divided into 8 groups with 65 images in each group. 13 junior ophthalmologists and medical students were selected as the research objects. Each of them read 8 groups of pictures and evaluated the DR grading of each fundus image. The sensitivity, specificity and diagnostic test consistency (Q-kappa value) of grading results were analyzed with the DR grading given by 3 senior ophthalmologists as the gold standard. The average Q-kappa values of 13 subjects were compared between the first four times and the last four times.Results:Through 8 round reading, the average Q-kappa was elevated from 0.67 to 0.81. Average Q-kappa of round 1 to 4 was 0.77, and average Q-kappa of round 5 to 8 was 0.81. The participants were divided into two groups. Participants in group 1 were junior ophthalmologists and participants in group 2 were medical students. Average Q-kappa of group 1 was elevated from 0.71 to 0.76. Average Q-kappa of group 2 was elevated from 0.63 to 0.84.Conclusions:The artificial intelligence reading label system was a useful tool in training junior ophthalmologists and medical students in doing diabetic retinopathy grading.

Objective To compare the effect of high volume continuous blood purification (CBP) with routine CBP on multiple organ dysfunction syndrome(MODS).Methods 38 patients with MODS were randomly divided into high volume CBP group( treatment group,18 cases) and routine CBP group (control group,20 cases).And they were respectively detected on mean arterial pressure(MAP),dosage of Dopamine,PaO2/FiO2,APACHE [ score,lactic acid,length of stay and mortality in ICU post-treatment 24h and 48h.Results Compared with control group,MAP and PaO2/FiO2 on treatment group were more higher( P ＜ 0.05 ),while dosage of Dopamine,APACHE Ⅱ score,lactic acid were significantly shorter than these of treatment group( P ＜ 0.05 ),and length of stay and mortality in ICU were significantly lower than those of treatmen group [ ( 8.54 ± 4.15 ) d vs ( 11.82 ± 5.76) d,P ＜ 0.05:22.2％ vs 35.0％,P ＜0.05 ].Conclusion High volume CBP could reduce the mortality in ICU compared with control group routine CBP.

ObjectiveTo explore the treatment options for fresh Grauer type Ⅱ odontoid fractures and discuss corresponding clinical outcome.Methods The study involved 40 patients with fresh odontoid fractures including seven with type Ⅱ A fractures, 18 with type Ⅱ B and 15 with type ⅡC according to Grauer classification.There were five patients with incomplete cervical cord injuries.Type Ⅱ A fractures were treated by traction of occipital-jaw band or skull for 1-2 weeks and then fixed with head-neck-chest plaster or brace.Type Ⅱ B fractures were treated with anterior odontoid screw system fixation.Fifteen patients with type Ⅱ C fractures and three patients with type Ⅱ B fractures combined with severe fracture displacement were managed with posterior atlantoaxial pedicle screw fixation.Results All the patients were followed up for 6-24 months.Seven patients with type Ⅱ A fractures showed union after fixation with head-neck-chest plaster or brace for 3-6 months.Fifteen patients treated with odontoid screw fixation had good positions of screws, with no injury to the spinal cord, of which 14 patients obtained bone union, with union rate of 93.3％.Eighteen patients (including 15 patients with type Ⅱ C fractures and three with type Ⅱ B fractures combined with severe displacement) managed with atlantoaxial pedicle screw system showed no injury to the vertebral artery and spinal cord.Solid bone fusion was achieved.in 31 patients after 3 to 6 months.The X-ray and SCT scans verified proper fixation of the screws, with no deformation, loosening or breakage of the screws.Five patients with incomplete cervical cord injuries obtained neural function recovery at various degrees after surgery.ConclusionsConservative treatment cau be alternative to type ⅡA fractures.Anterior odontoid hollow screw fixation is better for type ⅡB fractures (non-displaced or reducible) and has advantages of minor trauma, fast postoperative recovery and high union rate.However, posterior atlantoaxial pedicle screw system fixation and fusion is suitable to type Ⅱ C and ⅡB fractures with severe displacement and has the advantages of stable three-dimension fixation, direct screw placement, intraoperative reduction, short-segment fixation and high fusion rate.
