The appearance and changes of Acetylcholinesterase (ACHE) in the brains of 62 rats from early embryos to adults were studied by histochemical method and the brains of 19 rats of corresponding stages were examined with Nissl stain. The main results are as follows:1. AChE appeared in the following sequence: spinal cord, myelencephalon, metencephalon, mesencephalon, diencephalon and finally in telencephalon. In telencephaIon, AChE appeared earlier in paleocortex than in neocortex. The sequence described above showed that the appearance of AChE reflects cephalization of the nervous system in the rat.2. AChE-positive neurons of the rat brain consisted of cholinergic neurons and cholinoceptive ceils, both of which are related to the neurotransmitter ACh.3. The following nuclei of adult rat brain were shown to be AchE-positive in our specimens, but had not been reported in available literature: n. tractus mesencephali, n. anterior dorsalis thalami, n. anterior ventralis thalami, n. lateralis thalami, n. habenulae lateralis, n. reticularis thalami, n. supraopticus, n. paraventricularis, n. parafascicularis and n. ruber. In the cerebral cortex very few positive cells have been noticed.

Objective To explore the relationship of phospholipase A2 receptor (PLA2R) expression in renal tissue with clinical characteristics,prognosis of idiopathic membranous nephropathy (IMN) patients.Methods 134 patients diagnosed as nephropathy proven by biopsy was selected as subjects of this research,including 98 patients with IMN patients,10 patients with secondary membranous nephropathy and 26 patients with other renal glomerular diseases.The expression of PLA2R antigen in renal tissue was detected by immuno-fluorescence chemistry staining.Results The positive rate of renal PLA2R expression in IMN patients was higher than that in SMN patients (91.84％ vs 40.00％,P＜ 0.01),whereas there is no expression in other glomerular diseases.The PLA2R negative group were mainly stage Ⅰ membranous nephropathy,and positive group was mainly in stage Ⅱ.The distribution of pathological stage between the two groups was statistically significant (P ＜0.01).Compared with the positive group,the negative group was manifested with higher eGFR[(115.91± 23.32) ml· min-1 · (1.73 m2)-1 vs (94.06±27.38) ml· min-1 · (1.73 m2)-1,P=0.031],associated with the higher 12-month complete remission rate (87.50％ vs 44.07％,P=0.021).Conclusions The expression of PLA2R antigen in renal tissue plays an important role in the diagnosis,disease evaluation and prognosis of IMN.The negative PLA2R in kidney tissue of IMN may indicate a good clinical prognosis.

With the gradual maturity of renal replacement therapy technology, prolonging life span and improving quality of life of patients with uremia have become the ultimate management goals. In recent years, many studies at home and abroad have suggested that hypomagnesemia has an adverse effect on the prognosis of dialysis patients, which may be related to an increased risk of death. We understand the correlation between blood magnesium and blood pressure, cardiovascular disease, bone metabolism and vascular calcification, point out that blood magnesium may become one of the control indicators to reduce the mortality of dialysis patients, and explore its new clinical application.

Objective To explore the early predictive value of red cell distribution width (RDW) for contrast-induced nephropathy (CIN) in patients after enhanced computed tomography (CT). Methods A total of 218 patients who underwent enhanced CT between June 2015 and June 2017 at Huizhou Central Municipal Hospital were enrolled in this study. Patients were divided into CIN group and no-CIN group. The diagnostic criteria for CIN is an increase in serum creatinine (Scr) of more than 44.2 μmol/L or 25％ of the baseline value within 3 days of contrast agent use. The general information and clinical characteristics in two groups were compared. The risk factors of CIN were analyzed by logistic regression analysis. The receiver operator characteristic curve (ROC) was used to assess the value of RDW for predicting the occurrence of CIN. Results Among 218 patients, 10(4.59％ ) patients had CIN. In the CIN group age, baseline Scr and baseline RDW were significantly higher, while hemoglobin, baseline estimated glomerular filtration rate (eGFR), red blood cell, white blood cell, albumin, and high - density lipoprotein cholesterol were significantly lower than those in the no - CIN group (all P＜0.05). Binary logistic regression analysis revealed that baseline RDW (OR=2.250, 95％CI 1.031-4.911, P=0.042) and eGFR (OR=0.963, 95％ CI 0.928-0.999, P=0.044) were correlated with the occurrence of CIN. ROC analysis confirmed the area under the curve of RDW as a predictor of CIN was 0.798 (P＜0.001). The cut - off value of RDW was 14.5％ , and the diagnostic sensitivity and specificity in CIN were 70.00％ and 85.58％, respectively. Conclusions Increased baseline RDW and decreased eGFR are the risk factors of the occurrence of CIN after enhanced CT. RDW has a good predictive value, and it may be a good biomarker for the early diagnosis of CIN.

Purpose: Whether craniospinal irradiation (CSI) could be replaced by limited-field radiation in non-metastatic bifocal germinoma remains controversial. We addressed the issue based on the data from our series and the literature. Methods: Data from 49 patients diagnosed with non-metastatic bifocal germinoma at our hospital during the last 10 years were collected. The Pediatric Quality of Life Inventory 4.0 was used to evaluate health-related quality of life (HRQOL). Additionally, 81 patients identified from the literature were also analyzed independently. Results: In our cohort, 34 patients had tumors in the sellar/suprasellar (S/SS) plus pineal gland (PG) regions and 15 in the S/SS plus basal ganglia/thalamus (BG/T) regions. The median follow-up period was 52 months (range, 10 to 134 months). Our survival analysis showed that patients treated with CSI (n=12) or whole-brain radiotherapy (WBRT; n=34) had comparable disease-free survival (DFS; p=0.540), but better DFS than those treated with focal radiotherapy (FR; n=3, p=0.016). All 81 patients from the literature had tumors in the S/SS+PG regions. Relapses were documented in 4/45 patients treated with FR, 2/17 treated with whole-ventricle irradiation, 0/4 treated with WBRT, and 1/15 treated with CSI. Survival analysis did not reveal DFS differences between the types of radiation field (p=0.785). HRQOL analysis (n=44) in our cohort found that, compared with S/SS+PG germinoma, patients with BG/T involvement had significantly lower scores in social and school domains. However, HRQOL difference between patients treated with CSI and those not treated with CSI was not significant. Conclusion In patients with non-metastatic bifocal germinoma, it is rational that CSI could be replaced by limited-field radiation. HRQOL in patients with BG/T involvement was poorer.

Objective:To investigate the clinical effectiveness of anastomosis fixation method of lifting the suborbicularis oculi fat (SOOF) and fixing with the orbital septum and fat to correct eyelid bags with tear trough deformity.Methods:A retrospective analysis was conducted on patients treated at Hunan Provincial People’s Hospital (the First Affiliated Hospital of Hunan Normal University) from January 2019 to January 2021. The patients underwent lower eyelid blepharoplasty via a sub-lower eyelid skin approach. During the surgery, the SOOF was lifted and fixed with the orbital septum and fat, correcting the eye bags, filling the tear troughs, and lifting the midface. Postoperative observations included incision healing and complications. The correction of eye bags, tear troughs, and midface sagging was followed up. Adobe Photoshop CS6 software was used to measure the vertical distance from the nasolabial and buccal fat prominent point to the lower eyelid margin before surgery and at the last follow-up to evaluate the correction of midface sagging. Data were expressed as Mean ± SD, and pre- and post-operative comparisons were analyzed using paired t-test, with P<0.05 indicating statistical significance. Patients’ and nurses’ satisfaction evaluations of surgical outcomes were classified into three levels: satisfied, basically satisfied, and dissatisfied, requiring consensus between the two evaluators. Results:A total of 132 patients (264 eyes) were included, consisting of 23 males and 109 females, with an average age of (50.3±6.0) years. Hirmand tear trough classification included 178 type Ⅱeyes and 86 type Ⅲ eyes. Postoperative wound healing was well, with no hematoma, infection, diplopia, corneal foreign body sensation, and discomfort from external eye corner tightness. Follow-up ranged from 6-12 months, with 252 out of 264 eye bags disappeared and 12 eye bags reduced. Among the 86 type Ⅲ tear trough eyes, 10 improved to type Ⅰ, while the remaining 76 type Ⅲ and 178 type Ⅱ tear troughs disappeared postoperatively. All 264 midface sagging cases showed improvement, with the vertical distance from the nasolabial fat prominence point to the lower eyelid margin significantly shortening postoperatively [(29.23±1.58) mm vs. (34.08±3.23) mm, t=22.88, P<0.001)]. Satisfaction evaluation result showed 118 cases were satisfied (satisfaction rate of 89.4%), and 14 cases were basically satisfied. Conclusion:The anastomosis fixation method of lifting the SOOF and fixing with the orbital septum and fat effectively removes eyelid bags, smooths tear troughs, and lifts the midface, achieving a rejuvenated appearance and renders a high patient satisfaction rate.
