0.05),but the total expenses and antibiotic cost of the medical treatment in group B were obviously lower than those in group A(P

Objective To study the effects of one finger massage on sciatic nerve injury rats. Methods The sciatic nerves were exposed, and the sciatic nerve was held by micro needles to make the sciatic nerve injury model. SD rats were randomly divided into sham-operation group, model group and massage group. In the sham-operation group, the sciatic nerves were exposed but not held. 7 d after the establishment of modeling, rats in massage group received one finger massage for 30 d. After 30 d, SFI and BBB of sciatic nerves were detected. HE staining, transmission electron microscope and immunochemistry assay were used to measure the changes of sciatic nerves. Results Compared with model group, massage group could speed up the recovery of SFI and increase BBB, promote the recovery of sciatic nerve morphology, increased protein level of S-100β, and enhance ultrastructure of newborn nerve growth and recovery. Conclusion One finger massage can effectively promote neurological and functional recovery after sciatic nerve injury in rats.

Objective: To explore the emotional experience of abnormal fetal pregnant women after induced labor. Methods: Phenomenological methods were used to conduct in-depth interviews with 20 pregnant women with abnormal fetal induced labor from November 2018 to January 2019. Colaizzi analysis method was used to sort, code, classify, summarize and extract the subjects. Results: Two themes were extracted: Post-traumatic growth experiences and promotive factors of PTG. Post-traumatic growth experiences included traumatic reaction, new life attitude, exploring potential advantages, cherishing the relationship between relatives and friends, and actively seeking knowledge;Promotive factors of PTG included providing social support, mobilizing internal positive cognition, diverting attention, and planning for the future. Conclusions Medical staff should provide opportunities for pregnant women with abnormal fetal induced labor to express their emotions, fully integrate social and emotional support, mobilize internal positive cognition, and then promote their post-traumatic growth.

Objective:To evaluate the role of silencing regulatory protein (SIRT1) and its associated microRNAs (miRNAs) in dexmedetomidine-induced attenuation of renal damage in diabetic mice.Methods:SPF grade C57 male mice, aged 8 weeks, in which diabetes mellitus model was developed by intraperitoneal injection of 1% streptozotocin, were used.Thirty mice in which the model was successfully developed were divided into 5 groups ( n=6 each) using the random number table method: diabetes mellitus group (D group), diabetes mellitus + dexmedetomidine group (DD group), diabetes mellitus + dexmedetomidine + EX527 group (DDE group), diabetes mellitus + dexmedetomidine + miR-34a-3p-agomir group (DDH group), and diabetes mellitus + dexmedetomidine + miR-34a-3p-agomirNC group (DDC group). Six normal mice were selected as control group (C group). Dexmedetomidine 40 μg/kg was intraperitoneally injected once every 2 h, 3 times in total in DD, DDE, DDH and DDC groups.miR-34a-3p-agomir and miR-34a-3p-agomirNC 2.5 mmol were intraperitoneally injected via the tail vein at 72 h before dexmedetomidine administration once every 3 days, 2 times in total in DDH and DDC groups, respectively.SIRT1 inhibitor EX527 10 mg/kg was intraperitoneally injected at 1 h before dexmedetomidine administration in group DDE.At 24 h after the end of administration, serum concentrations of IL-6, IL-18, Cr and BUN, contents of nitric oxide (NO) and total antioxidant capacity (T-AOC), ROS activity, and expression of SIRT1, FoxO3a and P53 protein and mRNA, and expression of miR-217, miR-138 and miR-34a in renal tissues were determined. Results:Compared with group C, the serum IL-6, IL-18, Cr and BUN concentrations, contents of T-AOC and NO, and ROS activity were significantly increased, the expression of P53 protein and mRNA, miR-34a, miR-217 and miR-138 was up-regulated, and the expression of SIRT1 and FoxO3a protein and mRNA was down-regulated in group D ( P<0.05). Compared with group D, serum IL-6, IL-18, Cr and BUN concentrations, ROS activity and NO content were significantly decreased, T-AOC content was increased, the expression of SIRT1 and FoxO3a protein and mRNA was up-regulated, and the expression of miR-34a was down-regulated in group DD ( P<0.05). Compared with group DD, the serum IL-6, IL-18, Cr and BUN concentrations, NO content and ROS activity were significantly increased, T-AOC content was decreased, and the expression of SIRT1 and FoxO3a protein and mRNA was down-regulated in group DDE and group DDH ( P<0.05), no significant change was found in the expression of P53 protein and mRNA, miR-217, miR-34a and miR-138 in group DDE ( P>0.05), and the expression of P53 protein and mRNA and miR-34a was significantly up-regulated in group DDH ( P<0.05). Conclusions:The mechanism by which dexmedetomidine attenuates renal injury may be related to down-regulation of miR-34a expression, which further up-regulates SIRT1/FoxO3 expression and decreases oxidative stress in diabetic mice.

Objective To investigate the clinical features and risk factors of multidrug－resistant bacteria (multi drug resistant organisms, MDROs) infection in Department of Neurosurgery, and to provide evidence for the prevention and control of MDRO infection. Methods Data from 437 cases of infection in hospitalized patients on January 2012－2016 year in December Third Affiliated Hospital of Guizhou Medical University were retrospectively analyzed. Patients were divided into MDROs group and non MDROs group based on the results of MDROs detection. Multi factor Logistic regression analysis model was used to analyze risk factors. Results The infection rate of MDROs was 35.51%, and the detection rate of MDROs was 33.23% . ESBLs, CR－AB and MRSA were the most common bacterial species, and the infection of respiratory tract, urinary tract and wound infection were the main infection sites. Multivariate logistic regression analysis showed that hospitalization time ＞20 d, level of consciousness (coma), occupancy of ICU ≥7 d, ventilation (invasive), number of antibiotics used≥3, combined use of antibiotics≥3, mechanical ventilation Time≥7 d were possible risk factors for MDROs infection in neurosurgical patients (P＜0.05). Conclusion The situation of MDROs infection in neurosurgery is severe. To reduce MDROs infection, it is important to shorten unnecessary hospitalization time, promptly assess and transfer out of ICU as soon as possible, improve microbial examination, avoid frequent change of antibiotics or unnecessary use of use of broad－spectrum antibiotics, reduce unnecessary mechanical ventilation time, change to non－invasive ventilation as far as possible when the condition permits, focus on patients with poor consciousness, and prevent aspiration by mistake.

Objective:To investigate the screening values of immunocytochemical P16/Ki-67 double staining, P16 INK4α single staining and high-risk human papillomavirus (HR-HPV) testing for high-grade cervical lesions. Methods:The clinical data of 622 patients who underwent cervical thin-layer liquid-based cytology (TCT) and HR-HPV testing in General Hospital of Taiyuan Iron and Steel (Group) Co., Ltd. from March 2019 to July 2021 were retrospectively analyzed. The remaining cytological specimens were detected by P16/Ki-67 double staining and P16 INK4α single staining. Among them, 334 patients with TCT results suggesting atypical squamous cell of undetermined significance (ASCUS) and above and HPV-positive underwent colposcopy pathological biopsy. Using pathological results as reference, the positive predictive value, sensitivity, specificity and accuracy of P16/Ki-67 double staining, P16 INK4α single staining and HR-HPV testing for screening of high-grade squamous intraepithelial neoplasia (HSIL) and cervical cancer were compared. Results:Taking the results of histopathology as references, combined with the results of TCT, 31 of 622 patients were HSIL, of which 22 (71.0%) were positive for P16/Ki-67 double staining, 23 (74.2%) were positive for P16 INK4α single staining, and 25 (80.6%) were positive for HR-HPV testing; 4 cases were cervical cancer, and the positive rates of the three detection methods were all 100.0% (4/4). Among 622 patients, the positive rates of P16/Ki-67 double staining, P16 INK4α single staining and HR-HPV testing for screening of HSIL and cervical cancer were 13.99% (87/622), 25.40% (158/622) and 21.38% (133/622); the positive predictive values were 29.89%, 17.09% and 21.08%; the accuracies were 91.19%, 78.94% and 83.28%; the specificities were 89.77%, 77.98% and 82.46%; the sensitivities were 74.29%, 77.14% and 82.86%. The positive rate, positive predictive value, specificity and accuracy of P16/Ki-67 double staining were higher than those of P16 INK4α single staining and HR-HPV testing, and the differences were statistically significant ( z values were -5.062 and -3.418, 2.328 and 2.450, 5.436 and 3.570, 6.043 and 4.161, all P < 0.05); the sensitivity of HR-HPV testing was higher than that of P16/Ki-67 double staining and P16 INK4α single staining, but the differences were not statistically significant ( z values were -0.890 and 1.017, both P > 0.05). Conclusions:HR-HPV testing is more suitable for primary cervical lesion screening; P16/Ki-67 double staining can be used as a potential combined cell screening tool or an effective triage tool; P16 INK4α single staining has certain limitations.

The inositol polyphosphate-5-phosphatase ( INPP5E) gene encodes INPP5E, which is widely distributed in various tissues of humans and mice like the heart, brain and testis.It affects the phosphoinositide metabolic pathway by regulating the intracellular phosphatidylinositol triphosphate content, thus participating in intracellular signal transduction, cell proliferation and differentiation, cell polarity and other processes.The INPP5E gene plays a pivotal role in primary ciliogenesis and is closely related to childhood ciliary diseases.Therefore, this article review the research progress of the INPP5E gene in primary cilium-related pediatric diseases.Combined with laboratory findings, this review aims to provide new ideas for the regulation of the INPP5E gene in primary cilia and the prevention and treatment of pediatric ciliopathies.

Acid-base dissociation constant (pK_a) is a key physicochemical parameter in chemical science, especially in organic synthesis and drug discovery. Current methodologies for pK_a prediction still suffer from limited applicability domain and lack of chemical insight. Here we present MF-SuP-pK_a (multi-fidelity modeling with subgraph pooling for pK_a prediction), a novel pK_a prediction model that utilizes subgraph pooling, multi-fidelity learning and data augmentation. In our model, a knowledge-aware subgraph pooling strategy was designed to capture the local and global environments around the ionization sites for micro-pK_a prediction. To overcome the scarcity of accurate pK_a data, low-fidelity data (computational pK_a) was used to fit the high-fidelity data (experimental pK_a) through transfer learning. The final MF-SuP-pK_a model was constructed by pre-training on the augmented ChEMBL data set and fine-tuning on the DataWarrior data set. Extensive evaluation on the DataWarrior data set and three benchmark data sets shows that MF-SuP-pK_a achieves superior performances to the state-of-the-art pK_a prediction models while requires much less high-fidelity training data. Compared with Attentive FP, MF-SuP-pK_a achieves 23.83% and 20.12% improvement in terms of mean absolute error (MAE) on the acidic and basic sets, respectively.

A new definition of metabolic dysfunction-associated fatty liver disease (MAFLD) has recently been proposed. We aim to examine the associations of MAFLD, particularly its discordance from non-alcoholic fatty liver disease (NAFLD), with the progression of elevated brachial-ankle pulse wave velocity (baPWV) and albuminuria in a community-based study sample in Shanghai, China. After 4.3 years of follow-up, 778 participants developed elevated baPWV and 499 developed albuminuria. In comparison with the non-MAFLD group, the multivariable adjusted odds ratio (OR) of MAFLD group for new-onset elevated baPWV was 1.25 (95% confidence interval (CI) 1.01-1.55) and 1.35 (95% CI 1.07-1.70) for albuminuria. Participants without NAFLD but diagnosed according to MAFLD definition were associated with higher risk of incident albuminuria (OR 1.77; 95% CI 1.07-2.94). Patients with MAFLD with high value of hepamet fibrosis score or poor-controlled diabetes had higher risk of elevated baPWV or albuminuria. In conclusion, MAFLD was associated with new-onset elevated baPWV and albuminuria independently of body mass index, waist circumference, and hip circumference. Individuals without NAFLD but diagnosed as MAFLD had high risk of albuminuria, supporting that MAFLD criteria would be practical for the evaluation of long-term risk of subclinical atherosclerosis among fatty liver patients.
