ABSTRACT

Objective: To analyze the association between exposure patterns of adverse childhood experiences (ACEs) and anxiety symptom trajectories in medical college students. Methods: A survey was conducted on first-year students from Anhui Medical College and Anqing Medical College, using the Childhood Abuse Questionnaire, Family Disability Questionnaire, Childhood Adverse Social Experience Item, and Anxiety Self Rating Scale. The baseline survey was conducted from November to December 2019, and two follow-up visits were conducted once every six months until November to December 2020. The latent class analysis (LCA) was used to analyze the exposure patterns of ACEs. The latent class growth analysis (LCGA) was used to analyze the development trajectory of anxiety symptoms. The multiple logistic regression model was used to analyze the correlation between different exposure patterns of ACEs and the trajectory of anxiety symptom trajectories. Results: A total of 3 662 college students aged (19.2±1.0) were surveyed. The LCA showed that the exposure patterns of ACEs could be divided into the "high ACEs" group (13.4%), "high neglect/emotional abuse" group (25.7%), "high family dysfunction" group (6.9%), "high neglect" group (27.1%), and "low ACEs" group (26.3%). The LCGA divided anxiety trajectories into four groups: "high anxiety decline" (7.1%),"anxiety increase "(4.1%), "moderate anxiety"(52.9%), and "low anxiety"(35.9%). Using the low ACEs group as a reference group, compared with the low anxiety trajectory, the high ACEs group, high neglect/emotional abuse group, high family dysfunction group, high neglect group, and medium to high-level anxiety trajectory were all associated with an increased risk (P<0.05). Conclusion: There is heterogeneity in ACEs exposure patterns among medical college students, and ACEs exposure patterns are important influencing factors for anxiety symptom trajectories.

ABSTRACT

Objective To observe the protein expression related to cognitive and learning memory function, and to investigate the effect of aquaporin 4 (AQP4) silence on learning and memory function in traumatic brain injury (TBI) rats. Methods Ninety-six healthy adult male Wistar rats were divided into groups according to the random number table. ① Forty-eight rats were divided into sham operation (sham) group, TBI group (by using modified Feeney method), AQP4 RNA interference (RNAi) negative group [TBI+meaningless small interfering RNA (siRNA)-AQP4 liposome solution 10 μL], and AQP4 RNAi group (TBI+siRNA-AQP4 liposome solution 10 μL). In each group, brain tissues of 4 rats were harvested at 1, 6 and 12 hours respectively. The protein expressions of hippocampus AQP4, general control nonderepressible 2 kinase (GCN2), cyclic adenosine monophosphate response element binding protein (CREB) and phosphorylated CREB (p-CREB) were detected by Western Blot. ② In addition, 48 rats were divided into normal control group (control group), sham group, TBI group and AQP4 RNAi group, brain water content were measured in 6 of them after 12 hours of injury, and 6 were used in Morris water maze test. Results ① The protein expressions of hippocampus AQP4 and GCN2 in TBI group were significantly higher than those in sham group, and increased gradually with time with statistical difference at 12 hours (AQP4 protein: 5.03±0.09 vs. 1,GCN2 protein: 4.01±0.13 vs. 1, both 1 < 0.01);the protein expressions of hippocampus CREB and p-CREB were significantly lower than those in sham group, and decreased gradually with time with statistical difference at 12 hours (CREB protein: 0.38±0.03 vs. 1, p-CREB protein:0.38±0.03 vs. 1, both 1 < 0.01). Compared with TBI group, the protein expressions of AQP4 in AQP4 RNAi group was significantly decreased (1 hour: 1.02±0.04 vs. 2.23±0.05, 6 hours: 1.23±0.03 vs. 2.59±0.04, 12 hours: 2.20±0.08 vs. 5.03±0.09, all 1 < 0.01), but there were no significant difference in the expressions of GCN2, CREB or p-CREB. There was no significant difference in the expression of protein between AQP4 RNAi negative group and TBI group.② The brain water content in TBI group was significantly higher than that in control group and sham group [(83.7±0.4)% vs. (76.2±0.2)%, (76.2±0.3)%, both 1 < 0.01]. The brain water content in AQP4 RNAi group [(78.8±0.3)%] was significantly decreased as compared with that in TBI group (1 < 0.01). The latency of Morris water maze test was significantly prolonged in the day 11, 13 and 15 after the injury of the TBI group and AQP4 RNAi group, and the exploration time was significantly shortened. Compared with TBI group, the incubation period of AQP4 RNAi group was significantly shortened at 15 days (s: 60.2±11.1 vs. 62.0±11.5, 1 < 0.05), and the exploration time was significantly prolonged (s: 37.0±8.5 vs. 32.7±9.2, 1 < 0.05). Conclusions The impairment of cognitive and learning memory function in rats after TBI was significantly related to the changes in CREB and GCN2 in cognitive and learning memory function. After RNAi treatment, the cognitive and learning and memory function of rats was not improved obviously, but the brain edema could be alleviated.

ABSTRACT

Objective:To investigate the apoptotic induction effects of homoharringtonine (HHT) combined with imatinib (STI571) on human chronic myeloid leukemia (CML) KU812 cells. Methods:KU812 cells were treated with HHT or/and STI571. Total cell numbers were counted by using hemocytometer. Apoptotic cells were determined by using fluorescence microscope and FACS after staining with AO-EB and PI respectively. The cleavage of poly ADP-ribose polymerase (PARP) and the expression of anti-apoptotic proteins were determined by Western blot. Results:HHT could prompt the apoptotic induction of imatinib in KU812 cells, which was in a time and dose dependent manner. Apoptosis induced by HHT and imatinib was correlated with the down-regulation of Bcl-XL and the cleavage of PARP. Conclusion:HHT prompt apoptotic induction of imatinb in KU812 cells and the combination of HHT with imatinib will provide a more effective strategy for the clinical treatment of CML.

ABSTRACT

Since human society entered the 21st century, the rapid development of medical technology also gave birth to a series of negative effects:medical service technology first, trust crisis of the doctor-patient relation-ship, and medical industry money worship. Especially in recent years, due to the lack of humanistic spirit in medi-cal institutions, the doctor -patient relationship is of the worst state in the history. Therefore, it is urgent to strengthen the medical humanities education in the construction of hospital culture. Aiming at the problems existing in the current medical industry, this paper expounds the importance of strengthening the humanistic education in the construction of hospital culture.

ABSTRACT

Objective To investigate the effects of 4.1N expression in lung cancer A549 cell line on cell proliferation, invasion and migration. Methods A549 cells were cultured in vitro and transfected with lipofectamine 2000 mediation. Three groups were employed: transfection with pEGFP-4.1N plasmid, pEGFP vector plasmid, and blank control, respectively. The mRNA and protein expression differences of 4.1N was examined by semi-quantitative RT-PCR and Western blot in every group after 48 h. The proliferation capability was determined by MTT assay. Invasion capability was evaluated by scratches, adhesion experiments and Transwell chamber model. Results After the transfection, the expression of 4.1N mRNA and protein in pEGFP-4.1N plasmid transfection group was significantly enhanced (P<0.05). The proliferation capability of A549 cells descended extremely (P<0.05). The migration and invasion capability of A549 cells in vitro decreased substantially (P<0.05). Conclusions Transfected with 4.1N gene can significantly increases the expression levels of 4.1N mRNA and protein in A549 cells which are highly metastatic in human. Cell behavior in vitro studies showed that 4.1N gene can inhibit the proliferation, adhesion, invasion and migration of A549 cells, which plays an important role in the metastasis of lung cancer and it may become a molecular marker for metastasis of lung cancer.

ABSTRACT

Objective To investigate the protein expression of the canonical transient receptor potential(TRPC)channel in the hippocampus of amyloidβprotein(Aβ)?induced Alzheimer’s disease(AD)mice. Methods A total of 36 ICR mice were randomly divided into AD group and control group,with 18 rats in each group. AD mice models were established by Aβ1?42 microinjection into the lateral intracerebroventricular. Learning and memory abilities of the mice were determined using Morris water maze. All TRPC1?TRPC7 mRNA levels in the hippocampus of the mice were detected using reverse transcriptase polymerase chain reaction(RT?PCR). Hippocampal TRPC4 protein expression was examined using immunofluorescence and Western blotting methods. Results Water maze test results showed that the escape latency of AD group were significant?ly longer than that of the control group(P<0.01),and that the target quadrant occupancy of AD group was significantly shortened(P<0.01)and the frequency of platform crossing of AD group was significantly reduced(P<0.01). RT?PCR results showed that all TRPC(TRPC1?TRPC7) mRNA were expressed in the hippocampal of both AD group and control group. Among these channels ,only TRPC4 mRNA levels of AD group was higher than that of the control group(P<0.01). Immunofluorescence images showed that TRPC4 expressed on the membrane of neurons and the intensities of the immunofluorescence of TRPC4 in AD group were stronger than that of control group. Western blotting results showed that the TRPC4 protein expression of AD group was higher than that of control group(P<0.05). Conclusion The increase of TRPC4 protein expression in the hippocampus of mice after intracerebroventricular injection of Aβ1?42 oligomers suggests that TRPC4 may be involved in the pathogenesis of AD induced by calcium homeostasis.

ABSTRACT

Objective To investigate the effect of ethanol on level of the main hippocampal subtype of muscarinic receptor(M1)in mice,and evalu?ate whether the content change on this receptor could be linked with alterations in cognition,so as to further reveal the mechanism of brain damage in?duced by ethanol. Methods Sixty female mice were randomly divided into four groups. The model mice were induced by intragastric administration of ethanol at dose of 8%,16%,and 32%respectively of 0.2 mL/10 g for 8 weeks according to the protocol,and control group were treated with intra?gastric administration of distilled water. The capability of learning and memory were examined by Morris water maze,and ELISA method was used to measure the M1 receptor content in hippocampus in each group of mice. Results Compared with first day,the mean escape latency period on the fifth day was significantly shortened in each group. There was no significant difference between ethanol and control group for the mean escape latency period on the fifth day. Compared with the control group,the active time in the target quadrant was significantly shortened in 16%and 32%ethanol group. M1 receptor content in hippocampus formation was significantly decreased in all the ethanol group mice. The ethanol concentration was nega?tive correlated with the M1 receptor content. Conclusion Chronic alcoholism can induce the memory impairment in mice,which might be associat?ed with the low level of M1 receptor subtype in hippocampus of mice.

ABSTRACT

Objective To investigate the correlation of XRCC1 Arg194Trp Arg399Gln Single nucleotide polymor-phism (SNP) with radiotherapy response of squamous cell carcinoma of cervix. Methods Patients with exogenous type cer-vical squamous cell carcinoma confirmed by histopathology were selected for our study. These include:patients in stageⅠ(4 cases), patients in stageⅡ(36 cases), patients in stageⅢ(30 cases), patients in stageⅣ (3 cases). There are 30 patients with tumor diameter less than 4 cm and 43 patients with tumor diameter over 4 cm in our test. There are 36 cases with dose point A less than 80 Gy and 37 cases with dose point A over 80 Gy . Radiotherapy outcomes showed 47 cases of complete re-mission and 26 cases of part remission. Polymorphisms Arg194Trp, Arg399Gln of XRCC1 gene in 73 cervical cancer pa-tients were analyzed by mismatch amplification polymerase chain reaction (MAMA-PCR). Results Arg/Arg, Arg/Trp, TrP/Trp of Arg194Trp genotype distribution were 31 (42.5%), 37 (50.7%), 5 (6.8%) respectively. Arg/Arg, Arg/Gln, Gln/Gln of Arg399Gln distribution were 6 (35.6%), 39 (53.4%), 8 (11.0%) respectively. The response to radiotherapy was not statistical-ly significant in three genotypes, Arg/Arg, Arg/Trp, TrP/Trp of XRCC1 at codon 194(P>0.05). Neither was XRCC1 at codon 399. Multivariate analysis showed that late clinical stage was a risk factor of part remission. Conclusion SNP of XRCC1 gene at codon 194 and codon 399 could not predict clinical response of patients with squamous cell carcinoma of cervix to ra-diotherapy. The patients with advanced cervical cancer had poor response to radiotherapy.

The peptides of apelin and APJ expressed in the LV were detected with immunohistochemistry (IHC).</p><p><b>RESULT</b>Compared with C group, the mCAP, LVEDP and LVM/BW of M group were higher 36.58%, 333.8% and 20.24%, respectively (P<0.05, P<0.01, P<0.01). Compared with M group, LVEDP and LVM/BW of P group were lower 65.24% and 13.12%, respectively (both P<0.05). However mCAP was of no significant difference between these two groups. The levels of apelin-36 in the plasma and LV of M group were respectively higher 18.56% and 207.38% than those of C group (both P<0.05), while ones of P group were lower 24.21% and 49.40% than those of M group (both P<0.05). The expressions of apelin mRNA and APJ mRNA at left ventricle tissues of 2K1C rats were higher 77.66% and 119.00% (both P<0.05) than those of C group. The ones of P group were lower 27.40% and 45.66% than those of M group (both P<0.01). The IHC results indicate that the expressions of apelin and APJ peptides at left ventricle tissues of 2K1C rats were higher 129.51% and 154.1% (both P<0.01) than those of C group, respectively. Whereas the ones of P group were lower 65.36% and 62.87% than those of M group (both P<0.01).</p><p><b>CONCLUSION</b>Through regulating apelin/APJ system puerarin has protective effect on the development of left ventricular hypertrophy by renal hypertension.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the short-term outcome of patients receiving metal-on-mental hip resurfacing arthroplasty and analyze the factors affecting the result.</p><p><b>METHODS</b>In 13 patients receiving metal-on-metal hip resurfacing arthroplasties with scheduled follow-up, the treatment outcomes were assessed according to the Harris Hip Score.</p><p><b>RESULTS AND CONCLUSION</b>The short-term outcomes of hip resurfacing arthroplasties were encouraging, and intraoperative complications, infections, peripheral nerve palsy, hip dislocations or clinically overt lower limb deep vein thrombosis occurred in none of these cases. All the patients reported complete or major pain relief. Clinical assessment according to the Harris Hip Score revealed an improvement from an average score of 36.69 preoperatively to 89.63 after the surgery. Crutch use lasted for a maximum of 4 weeks postoperatively in these patients, after which the patients were all capable of walking without crutches with full weight-bearing.</p>
