Method Focal cerebral ischemia of spontaneous hypertensive rats wer e made by occlusion of the middle cerebral artery(MCA). Cilazapril treated group was taken cilazapril 4 weeks before model was made. TTC staining,HE staining,Nis sl's staining,immunohistochemistry, and image analysis were taken to estimate th e area of ischemia,number of dead neural cells,optical density of positive cell of Nissl's staining,HSP70 and NF-k BP65 immunohistochemistry reaction in ischem ia area. Result Cilazapril could reduce the area of ischemia and behavior sc ores,decrease the number of died neural ce lls,increase the optical density of positive cell of Nissl's staining,reduce th e optical density of NF-k BP65. No effect on HSP70 immunohistochemistry reactio n was found. Conclusion Cilazapril could decrease infarction of focal ischemia o f spontaneous hypertensive rats, promote the functional restoration of rats,decr ease nerve cell death,inhibit the expression of NF-k B. Cilazapril inhibited in flammatory reaction and that could be one of its protective mechanisms.

Objective:To explore the clinical signiifcance of the protection of superior petrosal vein (SPV) in the microneurosurgery for acoustic neuroma. Methods:From January 2009 to July 2011, 149 cases of acoustic neuroma microsurgery were observed. hTe difference in hematoma in surgical area, cerebellar hematoma and cerebellar edema were compared between a SPV without protection group (SPVWP group, n=8) and a SPV protection group (SPVP group, n=141). Results:In the 149 patients with acoustic neuroma, the SPV was reserved in 141 patients. In the SPVWP group (8 patients), hematoma in the surgery area occurred in 4 patients, cerebellar edema in 5, and cerebellar hemorrhage in 3. In the SPVP group (141 patients), hematoma in the surgery area occurred in 40 patients, cerebellar edema in 56, and cerebellar hemorrhage in 12. hTere was signiifcant difference in the incidence of cerebellar hemorrhage (χ2=3.84, P=0.05), no signiifcant difference in the incidence of hematoma in the surgical area (χ2=0.646, respectively, P=0.422), and no significant difference in the incidence of cerebellar edema (χ2=0.611, P=0.434) between the SPVWP group and the SPVP group. Conclusion:In acoustic neuroma surgery, the SPV should be protected, which may reduce the risk of cerebellar hemorrhage.

Objective To discuss the preservation and clinical significance of petrosal vein in microsurgical operation of acoustic neuroma. Methods 147 patients with acoustic neuroma were operated, with internal decompression of the tumor firstly then dissected the tumor with surrounding structures, the petrosal vein were protected well in 143 cases and failed to protect in 4 cases. Results No hemorrhagic infarction in cerebellar was observed in 143 cases with intact petrosal vein. One case occurred with extensive cerebellar edema, which has gait disturbance after 18 months follow-up. The other three cases occurred with vein infarction and hemorrhagic edema after petrosal vein damage. One was dead and the other two were recovered well after decompression of posterior cranial fossa. One has no significant neurological deficit after 33 months follow-up, while the other has difficulty in line walking after 12 months follow-up. Conclusion Petrosal vein should be well protected in the operation of acoustic neuroma, the decompression of posterior cranial fossa should be considered if petrosal vein failed to protect.

Objective To summarize the experience of the ventriculoperitoneal shunt (VPS) in communicating hydrocephalus and its complications. Methods The clinical features, operative techniques and outcome of 100 patients with hydrocephalus were analysed retrospectively. Results Ninety-five (95%) cases had a good result. Postoperative complications were found in 6(6%) cases including shunt apparatus blockage (4 cases) and shunt infection (2 cases). All the cases improved after taking the corresponding measures. Conclusion VPS is the most common shunt style for communicating hydrocephalus. The shunt apparatus blockage and infection are common postoperative complications. Intraoperative aseptic technique, the minimally invasive procedure, and the optimal placement of shunt tube may play an important role in improving the outcome of cerebrospinal fluid shunting surgery for communicating hydrocephalus.

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.

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 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.

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 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.

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.
