Objective To investigate the expression of nicotinic acetylcholine receptor (nAchR) subunits, and the effects of smoking on its expression in peripheral blood mononuclear cells (PBMCs). Methods Blood was collected from 92 healthy male smokers and 36 healthy male non-smokers. Peripheral blood monocytic cells were obtained, and reverse transcription-polymerase chain reaction (RT-PCR) was employed to study the gene expression of 11 nAchR subunits (?2-?7, ?9, ?10, ?2-?4). Results The results showed that the PBMCs of smokers and non-smokers appeared to express ?2, ?5, ?6 and ?7 only out of 11 nAchR subunits. However, the expression of ?5 and ?7 subunits was lower in smokers′ PBMCs than in non-smokers′ (P

Objective To study the diagnostic value of detecting pre-albumin,albumin and protein electrophoresis in the serum of patients with fever of unknown origin.Methods Serum pre-albumin,albumin and protein electrophoresis were detected in 86 patients with fever of unknown origin and 26 controls.Results The level of albumin and pre-albumin in fever of unknown origin group was lower than that of control group(P

Objective To investigate the clinical value of serum Haptoglobin (Hp)levels in cervical cancer patients.Methods Serum Hp (with immunoturbidimetry method),SCC,CA125 (with electrochemiluminescence immunoassay method)level were detected in 45 patients with cervical cancer,37patients with cervical benign disease and 41 female healthy controls.Re-sults Serum Hp level of cervical cancer patients (mean:1.69 g/L)was strongly higher than the level of cervical benign dis-ease patients (mean:0.90g/L)and healthy subjects (mean:0.69 g/L)(t=3.26,4.42,P=0.001,0.000,respectively).Hp level rises highly in the early stage of cervical cancer.The area under receiver operating characteristic curve (AUCROC)of Hp was 0.853 which was higher than SCC (AUC=0.751)and CA125 (AUC=0.494).The sensitivity of Hp,SCC,and CA125 were 87%,49% and 29% respectively.The specificity of Hp,SCC and CA125 were 68%,88% and 83% respective-ly.Three tumor markers combined together could produce a positive detection rate of 93%.Conclusion The detection of Hp has clinic significance on diagnosis of cervical cancer,and it’s possible to become a serum tumor marker.

Objective To investigate the impact of transtheoretical model-based depression management on senile people with type 2 diabetes. Methods A total of 78 senile patients with type 2 diabetes were recruited from the Affiliated Jiangyin Hospital of Southeast University Medical College and the Nantong Tumor Hospital during the period from September 2015 to December 2016.They were randomly divided into the experimental(n=39)and the control groups(n=39).The patients in the experimental group received transtheoretical model-based depression management while those in the control group received traditional health education. The intervention results were evaluated using Demographic Data Recording Form, Self-Rating Depression Scale, and Depression Prevention & Management Survey Items. The main statistical methods included Chi square test,independent sample t test,Mann-Whitney U test,and repeated measures analysis of variance. Results After the intervention of three months, the mean scores of Self-Rating Depression Scale was 50.97 (F=17.814), perceived benefit score was (9.59 ± 2.10) (t=-6.732), perceived barriers score was (5.59 ± 1.30) (t=2.980), cognitive level score was (32.98 ± 4.87) (t=-10.189), the behavior level score was (34.32 ± 5.02) (t=-13.745), and the self-efficacy score was (12.11 ± 2.13)(t=-7.845),all of which significantly improved in the experimental group,more than the control group with its perceived benefit score of(8.31 ± 1.12)(F=32.789),perceived barriers score of(6.99 ± 2.12)(F=18.788), cognitive level score of (29.01 ± 3.34) (F=67.876), behavior level score of (28.03 ± 4.77) (F=43.476), and self-efficacy score of(9.78 ± 2.03)(F=15.543),and the difference was statistically significant(P<0.01).The level of FPG in experimental group was(7.24 ± 1.36)mmol/L,which was significantly lower than the FPG of (7.41 ± 1.34)mmol/L in the control group(t=0.624,P=0.028).Conclusions Transtheoretical model-based depression management can effectively improve senile type 2 diabetes'management of depression,which is valuable in the clinical context.

Objective: To analyze the prevalence and trend of screening myopia among primary and middle school students in Linfen Community of Shanghai from 2019 to 2023, so as to provide a reference for the prevention and control of myopia from the perspective of the community. Methods: From 2019 to 2023, all primary(5) and middle(2) school students aged 6-15 years in Linfen Community of Shanghai were screened. Statistical analysis was performed using the Chi square test and trend Chi square test. The curve fitting model was used to fit the model of the increase rate of screening myopia among primary and middle school students in 2019, 2021 and 2023. Results: The overall rate of screening myopia among primary and middle school students in Linfen community from 2019 to 2023 was 55.17%. The prevalence rate of screening myopia was 79.43% in boys and 81.92% in girls in middle school, and the difference was statistically significant ( χ 2=5.71, P =0.02). In 2019, 2021, and 2023, the peak age of screening myopia among primary and middle school students in Linfen Community gradually occurred earlier, at the age of 7(12.13%), 6( 12.28 %), and 6(14.99%) years old, respectively. The growth rate of screening myopia in students aged 8-12 years in 2023 was lower than that in 2019 and 2021. Conclusions The screening myopia rate of primary and middle school students aged 6-15 years in Linfen Community is relatively high, with primary school girls higher than boys, and growth spurt accelerates. It is suggested that prevention and control of myopia in the community should focus on preschool children and adolescent girls.

Objective: To evaluate the efficacy and safety of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in prophylaxis neutropenia after chemotherapy in patients with lymphoma. Methods: This was a multicenter, single arm, open, phase Ⅳ clinical trial. Included 410 patients with lymphoma received multiple cycles of chemotherapy and PEG-rhG-CSF was administrated as prophylactic. The primary endpoint was the incidence of Ⅲ/Ⅳ grade neutropenia and febrile neutropenia (FN) after each chemotherapy cycle. Meanwhile the rate of antibiotics application during the whole period of chemotherapy was observed. Results: ①Among the 410 patients, 8 cases (1.95%) were contrary to the selected criteria, 35 cases (8.54%) lost, 19 cases (4.63%) experienced adverse events, 12 cases (2.93%) were eligible for the termination criteria, 15 cases (3.66%) develpoed disease progression or recurrence, thus the rest 321 cases (78.29%) were into the Per Protocol Set. ②During the first to fourth treatment cycles, the incidences of grade Ⅳ neutropenia after prophylactic use of PEG-rhG-CSF were 19.14% (49/256) , 12.5% (32/256) , 12.18% (24/197) , 13.61% (20/147) , respectively. The incidences of FN were 3.52% (9/256) , 0.39% (1/256) , 2.54% (5/197) , 2.04% (3/147) , respectively. After secondary prophylactic use of PEG-rhG-CSF, the incidences of Ⅳ grade neutropenia decreased from 61.54% (40/65) in the screening cycle to 16.92% (11/65) , 18.46% (12/65) and 20.75% (11/53) in 1-3 cycles, respectively. The incidences of FN decreased from 16.92% (11/65) in the screening cycle to 1.54% (1/65) , 4.62% (3/65) , 3.77% (2/53) in 1-3 cycles, respectively. ③The proportion of patients who received antibiotic therapy during the whole period of chemotherapy was 34.39% (141/410) . ④The incidence of adverse events associated with PEG-rhG-CSF was 4.63% (19/410) . The most common adverse events were bone pain[3.90% (16/410) ], fatigue (0.49%) and fever (0.24%) . Conclusion During the chemotherapy in patients with lymphoma, the prophylactic use of PEG-rhG-CSF could effectively reduce the incidences of grade Ⅲ/Ⅳ neutropenia and FN, which ensures that patients with lymphoma receive standard-dose chemotherapy to improve its cure rate.
