Myopia is a significant global health issue,and its exact causes are still not fully understood,leaving a lack of effective and propaqable treatment options.The prevalence of myopia among children and adolescents in China remains high,posing challenges for prevention and control efforts.According to the"theory of imbalance of essence and tendon",an imbalance in the essential elements and tendons can impede the passage of eye essence and blood,resulting in delayed expansion and contraction of the eye meridians and tendons,leading to blurred vision.Modern research indicates that during the development of myopia,there are notable changes in the microstructure,activation range,and signaling of various brain regions,providing a biological basis for the"brain-eye"mechanism.Moreover,abnormal activity in the brain nucleus contributes to alterations in choroid blood flow and the impairment of eye muscle regulation,thereby accelerating the progression of myopia,this phenomenon represents the manifestation of the brain-eye imbalance.Consequently,strategies for myopia prevention and control should prioritize nourishing kidney essence,replenishing brain marrow,promoting liver and blood health,and softening the meridians.These measures aim to optimize the functioning of the brain and eyes,maintain the flexibility of eye tendons,enhance eye regulation,sustain the strength of eye tendons,and delay the advancement of eye axis growth and myopia.By enriching the scientific understanding of the appropriate application of traditional Chinese medicine techniques to prevent and control myopia through the brain,this research provides valuable insights for future explorations in this field.

Objective:To investigate the effects of preoperative pre-rehabilitation on early functional recovery after knee arthroplasty under the multidisciplinary collaboration mode of accelerated rehabilitation surgery.Methods:The clinical data of 51 patients who underwent total knee arthroplasty in the Department of Orthopedics, Jinjiang Hospital from September 2019 to December 2021 were retrospectively analyzed. These patients were divided into an observation group ( n = 24) and a control group ( n = 27). The observation group received pre-rehabilitation before knee replacement surgery, while the control group did not. After completing the admission procedures, patients in the observation group underwent rehabilitation evaluation in the rehabilitation clinic and received individualized rehabilitation training. The control group did not undergo preoperative pre-rehabilitation but underwent the same individualized rehabilitation training as the observation group. The rehabilitation specialist evaluated the patients' rehabilitation scores [hospital for special surgery knee (HSS) score, visual analog scale (VAS) score] at 2 and 5 days after surgery. The main outcome measures included the range of motion (ROM) of the patient's knee joint at 2 and 5 days after surgery, HSS score at 2 and 5 days after surgery, VAS score at 5 days after surgery, the number of days from surgery to discharge, the incidence of postoperative complications, and the rate of outpatient visits after surgery. Results:There was no significant difference in postoperative ROM of the knee joint between the observation and control groups at 2 days after surgery ( P > 0.05). However, there was a significant difference in score of ROM of the knee joint at 5 days after surgery between the two groups [(100.08 ± 7.75) points vs. (88.44 ± 16.09) points, t = 3.34, P = 0.002]. There was no significant difference in HSS score between the two groups at 2 days after surgery ( P > 0.05). However, there was a significant difference in HSS score between the two groups at 5 days after surgery [(62.84 ± 5.78) points vs. (57.09 ± 6.53) points, t = 3.31, P = 0.002]. There was a significant difference in VAS score (exercise) between the two groups at 5 days after surgery [(3.42 ± 1.02) points vs. (5.37 ± 1.15) points, t = -6.39, P < 0.001]. There was no significant difference in the number of days from surgery to discharge between the two groups ( P > 0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P > 0.05). However, there was a significant difference in the rate of outpatient visits between the two groups [7/17 vs. 1/26, χ2 = 4.45, P = 0.035]. Conclusion:Preoperative pre-rehabilitation in the accelerated rehabilitation surgery model under multidisciplinary collaboration can help improve the early function of patients undergoing total knee arthroplasty, reduce the pain of postoperative rehabilitation, improve the postoperative rehabilitation compliance, and ultimately enhance patient satisfaction with the surgery.

Objective:To observe the therapeutic efficacy and prognosis of daratumumab combined with chemotherapy bridging to allogeneic hematopoietic stem cell transplantation (allo-HSCT) followed by daratumumab and lenalidomide maintenance treatment for primary plasma cell leukemia (PCL).Methods:The clinical data of a patient with primary PCL admitted to the First People's Hospital of Yunnan Province in January 2020 were retrospectively analyzed, and relevant literatures were reviewed.Results:The patient was diagnosed with primary PCL and treated with daratumumab combined with BD (bortezomib + dexamethasone) for 1 course and BCDD (bortezomib + cyclophosphamide + liposomaldoxorubicin + dexamethasone) for two courses. The patient was treated with daratumumab combined with allo-HSCT after complete remission. The donor cells were successfully implanted and the chimerism rate of donor cells was 94.36% without acute graft-versus-host disease reaction. And then the patient received intermittent maintenance therapy of daratumumab combined with low dose lenalidomide after transplantation, and the current remission period after transplantation reached 4 months.Conclusions:Daratumumab combined with chemotherapy bridging to allo-HSCT followed by daratumumab and lenalidomide may improve the prognosis of primary PCL and prolong survival time.

Objective: To explore the correlation between pull-up ability and upper body composition of male college students in a college in Guangxi, and to provide scientific guidance for college students’ exercise. Methods: A total of 685 male college students were randomly selected from a college in Guangxi.Pull up tests were implemented according to the national physical health test standards. Measurements of muscle mass, fat mass, fat percentage, etc. of the upper limbs were conducted by using the Ogilvy Body Composition Meter (TANITA MC-180). Data entry and analysis were performed by using SPSS 23.0. Results: The pass rate of male college students in the region was 21.7%; There was a statistically significant difference in the fat mass and percentage of body fat between males with different pull-up ability (F=11.30，14.18，12.91，15.22，P<0.01).After controlling age, height, weight and BMI, partial correlation analysis showed that there was a negative correlation between the pull-up ability of male college students and the fat mass and limb fat rate of both upper limbs(r=-0.22, -0.33, -0.31, -0.38, P<0.01). Conclusion The ability of male students in Guangxi to pull up is needed to be improved. Pull-up exercises can reduce fat mass and fat percentage in the upper limbs and improve body composition.

Objective:To investigate the clinical value of outpatient screening in department of general surgery during the Corona Virus Disease 2019 (COVID-19) outbreak.Methods:The retrospective and descriptive study was conducted. The clinical data of 57 patients who visited surgery clinic and emergency department of Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology between February 1st and 26th in 2020 were collected. There were 30 males and 27 females, aged (53±16)years, with a range from 17 to 87 years. All the 57 patients were measured score of outpatient screening in department of general surgery. The score ≥3 indicated high risk and the score < 3 indicated low risk. Observation indicators: (1) clinical data of patients; (2) score of outpatient screening for COVID-19 of patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed by the t test. Measurement data with skewed distribution were described as M (IQR), and comparison between groups was analyzed by the rank sum test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Results:(1) Clinical data of patients: of the 57 patients, there were 12 males and 14 females of the 26 confirmed or suspected cases, versus 18 males and 13 females of the 31 non-infection cases, showing no significant difference between the two groups ( χ2=0.805, P>0.05). The 26 confirmed or suspected cases of COVID-19 had an age of (57±16)years, and 31 non-infection cases had an age of (50±16) years, with no significant difference between the two groups ( t=-1.646, P>0.05). (2) Score of outpatient screening for COVID-19 of patients: the score of outpatient screening for COVID-19 of the 26 confirmed or suspected cases was 3.0(4.0), versus 1.0(1.0) of the 31 non-infection cases, showing a significant difference between the two groups ( Z=-3.695, P<0.05). There were 17 and 9 of the 26 confirmed or suspected cases with high risks and low risks, respectively, versus 3 and 28 of the 31 non-infection cases, with a significant difference between the two groups ( χ2=19.266, P<0.05). Conclusion:During the COVID-19 outbreak, outpatient screening in department of general surgery can effectively screen out high-risk patients.

BACKGROUND: Studying the relationship between flexibility and body composition of college students is of great significance for enhancing the levels of physical health and sports. OBJECTIVE: To investigate the relationship between sit-and-reach and body composition of college students in Guangxi Zhuang Autonomous Region and differences between sexes. METHODS: Totally 2 175 students from a Guangxi university were randomly selected. Body composition was determined by the MC-180 body composition tester. The students were divided into four groups: ≤ 12.10 cm group,＞ 12.10-16.40 cm group,＞ 16.40-20.70 group and＞ 20.70 group according to quartile of sit-and-reach measured in accordance with the National Physical Health Test Standard. All data were processed by SPSS 22.0 software. RESULTS AND CONCLUSION: Sit-and-reach was significantly correlated with body mass index, percentage of body fat, fat-free mass index, upper limb lean mass and lower limb lean mass (P ＜ 0.05), and percentage of body fat was negatively correlated with sit-and-reach (P ＜ 0.05). The body mass index, fat-free mass index, upper limb lean mass and lower limb lean mass in the ≤ 12.10 cm group were significantly lower than those in the other groups. Fat-free mass index and upper limb lean mass were correlated with sit-and-reach in male college students (P ＜ 0.05). The fat-free mass index and upper limb lean mass in the＞ 16.40-20.70 cm group were significantly higher than those in the ≤ 12.10 cm group. Therefore, there is a positive correlation between the flexibility and fat-free mass index and upper limb lean mass in college students.

Objective: To study the characteristics of gene mutations in Chinese myelodysplastic syndromes (MDS) patients. Methods: A total of 511 Chinese patients with MDS performed 112-gene targeted sequencing were retrospectively analyzed. Results: Eighty-three distinct mutant genes were found in 511 patients with MDS. Amongst these, the most frequent mutations was associated with epigenetics (50%) , followed by spliceosome (37%) , signal transduction (34%) , transcription factors (24%) and cell cycle/apoptosis (17%) . 439 subjects (86%) had at least one gene mutation. The mean number of mutations in refractory anemia with unilineage dysplasia (RCUD) was 1.25, refractory anemia with multilineage dysplasia (RCMD) was 1.73, refractory anemia with ring sideroblasts (RARS) was 2.79, refractory anemia with excess blasts-1 (RAEB-1) was 2.22, RAEB-2 was 2.34, MDS with isolated 5q- was 2.67, MDS, unclassified (MDS-U) was 2.00. U2AF1 mutant subjects were more likely to have isolated+8[Q<0.001, OR=4.42 (95% CI 2.23-8.68) ]and less likely to have complex karyotypes[Q=0.005, OR=0.22 (95% CI 0.04-0.72) ]. According to the number of gene mutations, all subjects were categorized into three groups, namely group with 0-1 mutation, with 2 mutations and with three or more mutations. There was a significant difference in overall survival (OS) among three groups (P=0.041) . Conclusion About 90% patients with MDS have at least one gene mutation. Genes associated with epigenetics and spliceosome are most common mutated genes in MDS. The increased numbers of gene mutations accompany with disease evolution and associate with poor prognosis.

To explore the influence of preventive use of vasopressin tannate on diabetes insipidus and serum sodium at the early postoperation of craniopharyngioma.
 Methods: The data of 83 patients, who underwent unilateral sub-frontal approach resection of craniopharyngioma between 2010 and 2014 by the same senior neurosurgeon, were retrospectively analyzed. The patients were divided into a vasopressin tannate group (used group) and a control group. The diabetes insipidus and serum sodium changes were compared between the two groups.
 Results: Compared with the control group, the incidence of diabetes insipidus decreased at the early postoperation in the vasopressin tannate group (P<0.05). There was high incidence of diabetes insipidus in patients with pituitary stalk excision and tumor close adhesion to the third ventricle floor at the early postoperation (P<0.05). Under such conditions, the incidence of diabetes insipidus in the vasopressin tannate group was decreased compared with the control group (P<0.05). Postoperative hypernatremia occurred in 37 patients (44.6%), and hyponatremia occurred in 60 patients (72.3%), the average time of the occurrence of hpernatremia and hyponatremia was 1.4 and 3.7 days after surgery. Postoperative high serum sodium and low serum sodium appeared alternately in 19 patients (22.9%). There was significant difference in the serum sodium distribution in the first day after surgery in both groups (P<0.05), and the percent of hpernatremia in the vasopressin tannate group was significantly less than that in the control group (P<0.05).
 Conclusion: Preventive use of vasopressin tannate can effectively reduce diabetes insipidus and hypernatremia incidence at the early postoperative stage after microsurgery for craniopharyngioma.

OBJECTIVETo identify factors that predictive of quality of life after microsurgical removal of petroclival meningiomas.

METHODSA consecutive series of 71 cases of petroclival meningiomas received microsurgical removal between July 1991 and April 2010 were analyzed retrospectively. Quality of life was measured using Karnofsky performance scale (KPS). Complete pre-operative, post-operative and follow-up data were obtained from all 71 patients including 18 male and 53 female patients with the mean age of (47 ± 11) years (aging from 15 to 68 years). The duration between onset of symptoms and diagnosis ranged from 1 week to 180 months with the mean duration of (32 ± 30) months. And the tumor size was 15-72 mm with the average of (44 ± 11) mm. Main presentations included headache, unsteady gait, hemiparesis, dysphagia, hoarseness, facial numbness or pain, Bell's palsy, hearing impairment etc. The preoperative KPS was 40-100 with the average of 69 ± 11. The retrosigmoid (-transtentorial) approach was performed in most cases (91.5%). Intergroup χ² test and logistic regression analysis were conducted for prognostic factor characterization.

RESULTSThe gross total resection (all were Simpson gradeII) reached in 48 cases (67.6%) and 1 case died postoperatively. The main new neurological dysfunctions were cranial nerve paralysis and hemiplegia with the postoperative KPS of 20-100 with the average of 73 ± 16.Sixty-four cases were followed for 4-132 months with the average of (61 ± 48) months. Seven patients died during follow-up, tumor recurrence and progression were identified in 6 and 8 cases, respectively. The KPS at the last visit ranged from 50 to 100 with the average of 83 ± 13. The extent of tumor resection (OR = 0.280, 95% CI: 0.081-0.967, P = 0.044), preoperative brainstem edema (OR = 0.100, 95% CI: 0.027-0.372, P = 0.001), relationships between tumor and neurovascular structures (OR = 0.288, 95% CI: 0.084-0.985, P = 0.047) and depth of invasion into cavernous sinus (OR = 0.254, 95% CI: 0.061-1.057, P = 0.048) had significant correlations with the prognostic quality of life.

CONCLUSIONSWith regard of the choice of surgical approaches, the extent of tumor resection, the protection of neurovascular structures surrounding the tumor and the management of perioperative period, the therapeutic strategies for each patient should be customized to achieve better prognosis.

Objective:To study the effect of microsurgery for parasellar menningiomas and to analyze the impact factors of recurrence. Methods:Clinical and follow-up data in a consecutive series of 134 patients with parasellar meningiomas were retrospectively analyzed. Results:A total of 109 patients (81.3%) had radical removal (Simpson grade I and II), and 116 patients were followed up for an average period of 81.6 months. The mean quality of life score (KPS) was 91.9, 90 patients regained full daily activity and 16 patients were able to take care of themselves. Oculomotor paralysis occurred in 7 patients, epilepsy in 8, and another 9 patients suffered hemispheral paralysis. Tumor recurred atfer the radical removal in 12 out of the 96 follow-up patients (12.5%). Tumor progressed atfer subtotal removal in 12 out of the 20 follow-up patients (60%). Tumor with cavernous sinus (CS) invasion had significantly higher risk of recurrence campared with non-CS invasion (P=0.043). The recurrence rate increased with the pathological grade (P<0.01). Conclusion:Patients with parasellar meningiomas undergoing microsurgical resection may have a good long-term function outcome. For most patients, total removal by microsurgery is the ifrst choice. Careful follow-up is needed if tumor invaded the CS and radiosurgery is proposed for WHO grade 1 and 2.
