ObjectiveTo analyze the disease and functioning characteristics of older adults with sarcopenia, the main exercise rehabilitation interventions, and its health benefits. MethodsLiterature related to exercise rehabilitation for older adults with sarcopenia was searched in PubMed, Medline, Embase, Cochrane Library and CNKI, from 2013 to 2023. The quality of included systematic reviews were evaluated. ICD-11 and ICF classification systems, and PICO framework from PRISMA guideline were used to report characteristics of the disease and functioning of the population, the exercise rehabilitation interventions, and its health benefits. ResultsFinally, seven systematic reviews from Netherlands, Spain, China, Brazil and Mexico were included, covering 98 related randomized controlled trials, involving 19 794 participants. These systematic reviews mainly came from the journals in the fields of aging, rehabilitation, nutrition, public health and physical exercise, and were published between 2018 and 2023. Exercise rehabilitation for sarcopenia were categorized into three types: exercise rehabilitation, exercise rehabilitation combined with nutritional supplementation, and exercise rehabilitation combined with nursing care. Interventions primarily included aerobic training, resistance training, gait training, strength training, and balance and flexibility exercises. The intervention frequency was six to 150 minutes, one to five times a week, with intensities ranging from low to high, over a duration of six to 144 weeks. The health benefits for older adults with sarcopenia from exercise rehabilitation were reflected in improvement in physical function and structure, and enhancement in activity and participation. In terms of body function and structure, exercise rehabilitation improved muscle strength, control, coordination, gait, balance, leg extension, leg press, back strength and grip strength, and increased muscle quality. In terms of activity and participation, exercise rehabilitation improved physical activity performance, such as walking speed and time of five-repetition chair stand test. ConclusionExercise rehabilitation for sarcopenia includes exercise rehabilitation, exercise rehabilitation combined with nutritional supplementation, and exercise rehabilitation combined with nursing care. Exercise rehabilitation can improve the physical function and structure, and enhance activity and participation.

Objective:To explore the value of the aMAP risk score (age, male, albumin -bilirubin, and platelets) to predict early recurrence within one year after microwave ablation in patients with small hepatocellular carcinoma. Methods:This was a retrospective study that enrolled 142 patients diagnosed with hepatocellular carcinoma who were treated with microwave ablation in the Department of Hepatology Unit of Nanfang Hospital, Southern Medical University from July 2016 to July 2021. The cohort enrolled 121 male and 21 female patients, including 110 patients that were <60 years old. All the patients were followed-up after microwave ablation to evaluate residual tumor and recurrence of tumor by computed tomography or magnetic resonance imaging. The observation indices mainly included general data and imaging data of patients. Using the X-tile tools, patients were divided into two groups: a high aMAP score group and a low aMAP score group. Multivariate Cox regression analysis was conducted for comparison of independent risk factors.Results:Multivariate Cox regression showed that high aMAP score, maximum tumor diameter >20 mm, and high AFP were the independent risk factors of early recurrence (all P<0.05). Kaplan-Meier survival curves showed that the median recurrence-free survival was 25.5 months in the low aMAP score group and 6.1 months in the high aMAP score group ( P=0.001). Conclusions:The aMAP score could predict the early recurrence within 1 year of small hepatocellular carcinoma after microwave ablation. Patients with high aMAP score should undergo rigorous postoperative follow-up evaluations..

Posner-Schlossman syndrome(PSS)is a sporadic and recurrent self-limiting anterior uveitis, and its pathogenesis remains unclear. It was considered to be a prostaglandin-mediated inflammatory response. In recent years, it has been found to be related to viral infection, immune genetics, vascular endothelial dysfunction, and other factors. Clinically, the disease is predominantly unilateral. The patients with PSS suffer from increased intraocular pressure, mild pain in the affected eye, as well as blurred vision, and irisopsia. Seldom damage to the optic nerve and visual field was reported. The commonly treatment of PSS is local medication, such as anti-inflammatory drugs and intraocular pressure lowering drugs; otherwise systemic medication can be employed in severe cases. Surgical treatment can be performed for PSS if uncontrolled intraocular pressure elevation, frequent attacks, and optic nerve damage and visual field defect due to prolonged disease course. Early diagnosis and treatment of PSS can effectively reduce glaucoma-related damages. This review discussed the research progress of PSS from various aspects, aiming to provide references for the etiology, pathogenesis, and clinical diagnosis and treatment of this disease.

Objective To compare the efficacy, safety, and survivability of TCbHP versus AC-THP in the neoadjuvant therapy of HER2-positive breast cancer in real-world. Methods Clinical data of patients with HER2 positive breast cancer, who have received TCbHP or AC-THP as neoadjuvant therapy and completed surgery in 11 third-class hospitals in various cities of Hebei Province, were retrospectively collected.The total pathological complete remission (tpCR) rate, the incidence of grade 3 or higher adverse reactions and the completion rate of the given approaches were compared. Results A total of 110 cases were collected, including 78 cases in the TCbHP group and 32 cases in the AC-THP group.The tpCR rate of the TCbHP group was higher than that of the AC-THP group, but the difference was not statistically significant (64.10% vs. 56.25%, P=0.441).No significant difference was found in the breast pathologic complete response (bpCR) and axillary pathologic complete response (apCR) rates between the TCbHP group and the AC-THP group (70.51% vs. 56.25%, P=0.150;78.21% vs. 84.38%, P=0.462).Exploratory analysis revealed that the tpCR rate of the TCbHP group was significantly higher than that of the AC-THP group in patients with HR-positive breast cancer (51.11% vs. 22.22%, P=0.036).As for the patients with HR-negative breast cancer, the tpCR rate of the AC-THP group tended to be higher than that of the TCbHP group (100% vs. 81.82%, P=0.088).The incidence of grade 3 or higher adverse reactions in the TCbHP group was slightly higher than that in the AC-THP group (12.82% vs. 9.38%, P=0.753).No deaths occurred in the whole group.Moreover, no significant difference was observed in the completion rate of the given approaches between the TCbHP group and the AC-THP group (92.31% vs. 90.63%, P=0.718). Conclusion In real-world clinical practice, the neoadjuvant therapy of TCbHP and AC-THP are effective, safe, and well tolerated among patients with HER2-positive breast cancer.The tpCR rate between the two approaches was not significantly different.The AC-THP regimen could also be considered as one of the optimal regimens for HER2-positive breast cancer in neoadjuvant therapy.

It is an effective way to improve the early diagnosis rate of hepatocellular carcinoma (HCC) in China by conducting standardized screening among the population with chronic liver diseases, achieving accurate stratification and standardized management of the population at a risk of HCC, and realizing the early warning for HCC through effective technical means. In clinical practice, the risk scoring models for liver cancer including aMAP can be used for preliminary risk screening of the population with chronic liver diseases to identify the population with a moderate or high risk of liver cancer. Novel serum biomarkers can be used to further screen out the population with an extremely high risk of liver cancer, and then imaging technology can be used for early diagnosis. Constant exploration and improvement of the "pyramid" screening and management mode through stratified enrichment may help to achieve the goal of improving early diagnosis rate of HCC and reducing HCC-related mortality.

Objective@#Neonatal exposure to propofol has been reported to cause neurotoxicity and neurocognitive decline in adulthood; however, the underlying mechanism has not been established.@*Methods@#SD rats were exposed to propofol on postnatal day 7 (PND-7). Double-immunofluorescence staining was used to assess neurogenesis in the hippocampal dentate gyrus (DG). The expression of p-Akt and p27 were measured by western blotting. The Morris water maze, novel object recognition test, and object location test were used to evaluate neurocognitive function 2-month-old rats.@*Results@#Phosphorylation of Akt was inhibited, while p27 expression was enhanced after neonatal exposure to propofol. Propofol also inhibited proliferation of neural stem cells (NSCs) and decreased differentiation to neurons and astroglia. Moreover, the neurocognitive function in 2-month-old rats was weakened. Of significance, intra-hippocampal injection of the Akt activator, SC79, attenuated the inhibition of p-AKT and increase of p27 expression. SC79 also rescued the propofol-induced inhibition of NSC proliferation and differentiation. The propofol-induced neurocognition deficit was also partially reversed by SC79.@*Conclusion@#Taken together, these results suggest that neurogenesis is hindered by neonatal propofol exposure. Specifically, neonatal propofol exposure was shown to suppress the proliferation and differentiation of NSCs by inhibiting Akt/p27 signaling pathway.

For sexual reproduction, oocytes are mammalian female germ cells that provide the majority of maternal genetic material for early stage embryo production and development. Early stage embryos begin the process of multicellular organism formation through cell differentiation. Studies on mammalian female germ cells (oocytes) not only reveal its unique physiological characteristics, but also help understand the mechanism involved in cell differentiation of other cell types. However, because it is difficult to culture in vitro, our understanding of the function of oocytes and early stage embryos remains very limited. Gene editing or manipulation is one of the most commonly used method, which is also useful in the field of gametes study. In this review, we summarized the principles, advantages and disadvantages of techniques, which include conditional knockout, RNA interference, Morpholino, Trim-Away and antibody-mediated inhibition of protein function, currently used for gene manipulation in oocytes and early stage embryos. We also discuss the issues the investigators need to consider. Finally, we highlight the future directions for gene manipulation or editing in female germ cells and early stage embryos.

OBJECTIVE@#To analyze the effectiveness and safety of one stage three column osteotomy in treatment of scoliosis with split spinal cord malformation.@*METHODS@#The clinical data of 41 patients with scoliosis and split spinal cord malformation underwent one-stage three-column osteotomy from January 2015 to December 2017 were retrospectively analyzed. There were 17 males and 24 females with average age of (25.14±4.51) years old and the average weight of (65.14±9.11) kg. According to the classification of longitudinal spina bifida, 15 cases of Pang typeⅠwere group A and 26 cases of Pang typeⅡwere group B. The general situations of two groups were recorded ; preoperative and postoperative Cobb angle were observed and the correction rate of Cobb angle of coronal plane was calculated ; the coronal and sagittal torso offset distances were compared between two groups and the trunk balance was evaluated ; the complication of two groups was recorded.@*RESULTS@#All 41 patients were followed up for more than 12 months. The operation time, intraoperative blood loss, and perioperative blood transfusion volume in group A were (610.14±115.02) min, (4 001.12±1 014.33) ml, (3 951.14±1 021.55) ml, respectively, and group B were (520.12±101.14) min, (2 701.57±1 021.45) ml, (2 565.77±880.47) ml, the difference between the two groups was statistically significant (0.05). There was no significant difference in postoperative coronary Cobb angle and correction rate between two groups (>0.05). Immediately after surgery and 12 months after surgery, there was no significant difference in the trunk displacement distance of coronal view and sagittal view between two groups (>0.05). Six patients in group A had complications, which was higher than that in group B of 1 case (=4.885, < 0.05).@*CONCLUSION@#One-stage three-column osteotomy in treatment of scoliosis with split spinal cord malformation has high correction rate and good balance of the trunk. However, for patients with typeⅠsplit spinal cord malformation, they will face longer operation time, more intraoperative bleeding volume, large amount of perioperative blood transfusion and higher risk of complications, and the safety is not as good as that of typeⅡpatients. Therefore, in the actual treatment of scoliosis, especially for those with typeⅠsplit spinal cord malformation, a more reasonable surgical plan should be developed in combination with the actual situations of the patients, so as to improve the safety of the operation.

Objective To design a new type of external fixator for bone fracture and verify its rationality and feasibility. Methods The frame and screw of stainless steel achieved fracture fixation in vitro with a threaded locking structure.At the same time the increasing thickness of body frame, the inclined nail holes and the raised bottoms were designed to greatly enhance the strength and overall stability of body frame.FEM (finite element method),measuring the relative displacement and stress distribution after axial load,was used to verify the rationality of the design.An animal experiment with sheep was used to verify the feasibility of fracture treatment. Results Simulated result of FEM indicated that the biggest relative displacement between the separated bones was 0.04 mm,which was much less than the minimum value 1 mm required for fracture healing.The maximum stresses applied on the frame of the fixator,fixator screw,and bone were 35,26,and 6 MPa, respectively, which was much less than the allowable stress. In the animal experiment, fracture site was fixed firmly after operation and was well cured 3 months later.Conclusion The design of this new device is feasible and it can be used as a new method of fracture treatment.
