Objective To preliminarily investigate the related factors influencing the size of vestibular schwannomas.Methods The clinical data of patients with vestibular schwannomas who underwent retrosigmoid approach surgery at the department of neurosurgery of First Affiliated Hospital of Xinjiang Medical University from June 2013 to June 2023 were retrospectively analyzed.The tumor size of the patients was evaluated based on their preoperative imaging data.Univariate and multiple linear regression analyses were performed to explore the factors affecting the size of vestibular schwannomas.Results The tumor size of patients was ranging from 0.63 to 6.60 cm,with a median size of 2.97(2.20,3.80)cm.Univariate analysis showed that gender(P=0.010),ethnicity(P=0.001),age(P=0.049)and cystic solid tumor(P<0.001)were related to the size of vestibular schwannomas.Large-sized vestibular schwannomas were most commonly cystic-solid,and small and medium-sized vestibular schwannomas were most commonly solid.BMI,surgical side and place of residence were not correlated with the size of vestibular schwannomas(P>0.05).Multiple linear regression results showed that male(B=0.390,P=0.001)and Uyghur(B=0.611,P<0.001)patients were more likely to develop large tumors;with every 1-year increase in age,the maximum diameter of the tumor was reduced by an average of 0.011 cm(B=-0.011,P=0.027).Conclusion The gender,age,and ethnicity of patients are correlated with the size of vestibular schwannomas,and male,Uyghur,or younger patients were at higher risk of developing larger vestibular schwannomas.

Pruning branches and leaves is the measure to stimulate the growth of Lonicera japonica flower buds, and consequently, the resources of pruned leaves are inevitably and seriously wasted in production. High-performance liquid chromatography(HPLC) was applied for content determination of seven active ingredients(chlorogenic acid, galuteolin, isochlorogenic acids A, B, and C, secologanic acid, and secoxyloganin) in L. japonica leaves from March to November. The results showed that the tillering removed from the trunk of L. japonica in March, the leaves pruned from May to July, and the leaves after the first frost date in November were rich in active ingredients, which deserved further exploitation and utilization. The total content(TC) of active ingredients in pruned L. japonica leaves in early March was the highest. The content of active ingredients in L. japonica leaves increased significantly after the first frost date, which was close to that in the bud tillers pruned in early and middle March. After the first frost date, L. japonica leaves are incapable of photosynthesis, and the harvesting of L. japonica leaves does not affect the physiological activities of the tree. In addition to huge resources, the content of active ingredients is high during this period, which is the best harvesting period of L. japonica leaves.

Based on the results of previous data mining,the mechanism of high frequency use of Tibetan medicine in the treatment of high altitude polycythemia(HAPC) was analyzed in this study by network pharmacology. The author obtained the high frequency use data on Tibetan medicine Terminalia chebula,Aucklandia lappa,Crocus sativus and Myristica fragrans for the treatment of HAPC by data mining in the previous period. The first five main active ingredients of each high frequency Tibetan medicine were screened out by reviewing comprehensive literature and TCMSP database. The potential targets of each medicine were screened by PharmMapper and Drug Bank database,and then the targets were imported into MAS 3. 0 database to obtain the corresponding path information. The KEGG database was used for path annotation and GO function enrichment analysis. Finally,Cystoscope 3. 4. 0 software was used to construct " compound-target-path" network for four high-frequency Tibetan medicines. Among them,the target points of four herbs related to HAPC were 16(T. chebula),20(A. lappa),20(C. sativus),and 15(M. fragrans). The common target points included BHMT,F2,ADH5,AKR1 C2,GSK3 B,INSR and PDE4 B,involving pathways related to T. chebula(17),A. lappa(17),C. sativus(24) and M. fragrans(14),and the common pathway was metabolism of xenobiotics by cytochrome P450. The results showed that high-frequency Tibetan medicine had common pathways and targets in treating HAPC,such as T. chebula,A. lappa,C. sativus and M. fragrans.The medicines could reduce hemoglobin and enhance immunity by mediating cell proliferation and oxidative stress,exerting anti-inflammatory effects and participating in regulating blood vessels,showing therapeutic effects for HAPC. In this study,the multi-component,multi-target and multi-pathway mechanism of Tibetan medicine in preventing and treating HAPC was analyzed from the information level,providing a useful reference for further study of Tibetan medicine in preventing and treating plateau diseases from the multi-dimensional perspective.

OBJECTIVETo evaluate efficacy and advantages of the Traditional Chinese Medicine (TCM) synthetic rehabilitation therapy in the treatment of wrist dysfunction after distal radius fractures.

METHODSFrom May 2014 to October 2015, 72 patients with distal radius fracture meeting standards were treated using central randomization system for clinical research. All the patients were divided into two groups: 36 patients in test group and 36 in control group. Sixty-nine cases were finished treatment and followed up in the end. The test group fell off 1 case, and the control group fell off 2 cases. The test group was given TCM synthetic rehabilitation (manipulative therapy, joint mobilization, soaking-washing with Chinese medicinal herbs, functional exercise), and the control group was given functional exercise as well as soaking-washing with Chinese medicinal herbs, 3 weeks for both. Five evaluation standards were used in this research, which were grip strength, patient-rated wrist evaluation (PRWE), Gartland and Werley wrist score, self-rating anxiety scale(SAS) and the overall curative effect evaluation. Before treatment(baseline), after 3 weeks of treatment and 3 months after fracture were the three points in time when collected the data.

RESULTSAfter 3 weeks of treatment and 3 months after fracture, the test group had a significantly better results than those of control group in the PRWE, G-W wrist score and the overall curative effect evaluation(<0.05). In terms of grip strength recovery, after 3 weeks of treatment, the intergroup difference between the test group and the control group were statistically significant relative to the baseline regarding grip strength of ipsilateral wrist by group t-test(<0.05). However, the test group and the control group had no statistically significant relative to the baseline at 3 months after fracture in grip strength(<0.05). For the anxiety of patients, compared with the test group and control group at before and after rehabilitation treatment, the anxiety of both test group and control group cases was eased(<0.05). However, The degree of anxiety relief in test group and control group cases had no difference(>0.05).

CONCLUSIONSThe TCM synthetic rehabilitation therapy has better curative effects on the treatment of functional disability of wrist joints after distal radius fractures than the general therapy of soaking-washing with Chinese medicinal herbs and functional exercise.

To establish a method for the identification of five species and one variety of medicinal plants from Diospyros, their leaf veins, epidermis, anatomic and powder characters were observed and compared with macro-morphological and microscopic methods. The results indicated the differences of secondary and tertiary veins among those Diospyros species. The single cell non-glandular hair and glandular hair exist in most species' epidermis while stone cells were only found in the leaf powders of two species. Through the study, the main differences of leaf macro- and micro-morphology of these species were obtained and practical keys were also established, which can provide scientific base not only for identification of these species during their vegetative stages, but also for accuracy authentication of the source of Kaki Folium.

Vertical sleeve gastrectomy (VSG) is becoming more and more popular among the world. Despite its dramatic efficacy, however, the mechanism of VSG remains largely undetermined. This study aimed to test interferon (IFN)-γ secretion n of mesenteric lymph nodes in obese mice (ob/ob mice), a model of VSG, and its relationship with farnesoid X receptor (FXR) expression in the liver and small intestine, and to investigate the weight loss mechanism of VSG. The wild type (WT) mice and ob/ob mice were divided into four groups: A (WT+Sham), B (WT+VSG), C (ob/ob+Sham), and D (ob/ob+VSG). Body weight values were monitored. The IFN-γ expression in mesenteric lymph nodes of ob/ob mice pre- and post-operation was detected by flow cytometry (FCM). The FXR expression in the liver and small intestine was detected by Western blotting. The mouse AML-12 liver cells were stimulated with IFN-γ at different concentrations in vitro. The changes of FXR expression were also examined. The results showed that the body weight of ob/ob mice was significantly declined from (40.6±2.7) g to (27.5±3.8) g on the 30th day after VSG (P<0.05). At the same time, VSG induced a higher level secretion of IFN-γ in mesenteric lymph nodes of ob/ob mice than that pre-operation (P<0.05). The FXR expression levels in the liver and small intestine after VSG were respectively 0.97±0.07 and 0.84±0.07 fold of GAPDH, which were significantly higher than pre-operative levels of 0.50±0.06 and 0.48±0.06 respectively (P<0.05). After the stimulation of AML-12 liver cells in vitro by different concentrations of IFN-γ (0, 10, 25, 50, 100, and 200 ng/mL), the relative FXR expression levels were 0.22±0.04, 0.31±0.04, 0.39±0.05, 0.38±0.05, 0.56±0.06, and 0.35±0.05, respectively, suggesting IFN-γ could distinctly promote the FXR expression in a dose-dependent manner in comparison to those cells without IFN-γ stimulation (P<0.05). It was concluded that VSG induces a weight loss in ob/ob mice by increasing IFN-γ secretion of mesenteric lymph nodes, which then increases the FXR expression of the liver and small intestine.

OBJECTIVETo explore the effect of repeated hypoxic preconditioning (RHP) on renal ischemia-reperfusion-induced hepatic dysfunction in rats and the underlying mechanism.

METHODSA total of 120 normal SD rats were randomly divided into 4 groups (n=40), namely RHP surgical group, RHP sham-operated (RHPS) group, nonhypoxic surgical group (IRI group), and nonhypoxic sham-operated group (S group). The rats in the hypoxic groups were exposed to hypoxia in a hypoxic chamber for 5 days prior to establishment of renal ischemia-reperfusion model by resection of the right kidney and clamping the left renal hilum. Serum alanine aminotransferase (ALT), IL-17 A, TNF-a, liver superoxide dismutase (SOD) and nitric oxide (NO) were detected at 2, 8 and 24h after reperfusion, and Western blotting was used to determine the expression of p-PI3K and p-AKT;HE staining was used to observe the structural changes in the liver.

RESULTSCompared with IRI group, RHP group showed significantly milder hepatic damage, lower ALT levels and higher NO levels at 2, 8, and 24 after reperfusion (P<0.05); TNF-a levels were lowered at 24 h (P<0.05) and SOD increased at 8 h after the reperfusion (P<0.05). Compared with S group, IRI group and RHP group showed significantly higher IL-17A levels (P<0.05) but without significant difference between the latter two groups (P>0.05). The expressions of p-PI3K and P-Al

CONCLUSIONRepeated hypoxic preconditioning can attenuate hepatic injury induced by renal ischemia-reperfusion injury in rats.

OBJECTIVETo evaluate the efficacy of Bufei Yishen Granule BFYSG) combined with Shufei Tie acupoint sticking therapy on quality of life of patients with stable chronic obstructive pulmonary disease (COPD).

METHODSA multi-center, double-blinded, double-dummy and randomized controlled method was adopted in this trial. A total of 244 patients were randomly assigned to a trial group and a control group according to the random number, each with 122 patients; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent form. In the trial group, patients were treated with BFYSG combined with "Shufei Tie" acupoint sticking therapy and sustained-release theophylline dummy, and in the control group patients were treated with oral sustained-release theophylline and BFYSG dummy combined with "Shufei Tie" acupoint sticking therapy dummy. The therapeutic course for two groups was 4 months and the follow-up was 6 months. The frequency and duration of acute exacerbation calculated by adding up each frequency and duration of acute exacerbation in treatment and follow-up time respectively, the quality of life measured by the World Health Organization Quality of Life (WHOQOL)-BREF scale and adult COPD quality of life (COPD-QOL) scale were observed.

RESULTSAmong the 244 enrolled patients, 234 were screened for full analysis set (FAS); 221 were screened for per-protocol analysis set (PPS). After 4-month treatment and 6-month follow-up there were differences between the trial group and the control group in frequency of acute exacerbation (FAS: P=0.013; PPS: P=0.046); duration of acute exacerbation (FAS: P=0.005; PPS: P=0.006); scores of physiological, psychological and environment aspects of the WHOQOL-BREF questionnaire (FAS: P=0.002, P=0.006, P=0.000; PPS: P=0.00, P=0.001, P=0.000); scores of daily living ability, social activity, depression symptoms aspects of the COPD-QOL questionnaire (FAS: P=0.000, P=0.000, P=0.006; PPS: P=0.002, P=0.001, P=0.001).

CONCLUSIONBFYSG combined with acupoint sticking therapy could improve the quality of life of patients with stable COPD.

This study was aimed to investigate the c-kit mutation in acute myeloid leukemia (AML) patients with AML1-ETO and analyze its relation with clinical and laboratorial features and prognosis. PCR and sequencing methods were used to detect the c-kit 17 exon mutations in 31 AML patients with AML1-ETO. The relation of the c-kit mutation with clinical features, results of laboratorial examination and prognosis of disease were analyzed. The results showed that the c-kit mutation was found in 14 out of 31 AML patients and the mutation frequency was 45.16%. Male patients had a higher incidence of c-kit mutation than that of female patients (P = 0.020). The proportion of patients with newly diagnosed white blood cell>10×10(9)/L and with extramedullary infiltration in mutated group were higher than those in unmutated group respectively. No significant difference was observed at the age (P = 0.437) and the rate of bone marrow blasts(P = 0.510) between the above mentioned two groups. The difference in complete remission rate (64.29% vs 80%, P = 0.344)and relapse rate (58.33% vs 21.43%, P = 0.054) between c-kit mutated and c-kit unmutated groups were not significant. While the c-kit mutated group had a significant higher death rate as compared with c-kit unmutated group (57.14% vs 20%, P = 0.039). It is concluded that the c-kit mutation is frequent in AML patients with AML1-ETO and the c-kit mutated patients have a poor prognosis. It is important to detect c-kit mutation in routine clinical practice for patient's risk stratification, evaluation of prognosis and selection of effective treatment.

BACKGROUNDAnisodamine is widely used in therapy for treating acute glomerulonephritis and diabetic nephropathy because it can improve renal microcirculation. We performed a study to evaluate the preventive effects of anisodamine against contrast-induced nephropathy (CIN) in type 2 diabetics with renal insufficiency undergoing coronary angiography or angioplasty.

METHODSA total of 260 patients with type 2 diabetes and an estimated glomerular filtration rate (eGFR) of 60 ml(-1)×min(-1)×1.73 m(-2) or less, who were undergoing coronary angiography or angioplasty, were randomly assigned to receive an infusion of either sodium chloride (control group, n = 128) or anisodamine (treatment group, n = 132). Patients in the treatment group received an infusion of anisodamine at a rate of 0.2 µg×kg(-1)×min(-1) from 12 hours before to 12 hours after coronary angiography or angioplasty, while patients in the control group received an infusion of sodium chloride with the same volume as the treatment group. All patients received intravenous sodium chloride hydration. CIN was defined as a 25% increase in serum creatinine from baseline or an absolute increase of > 0.5 mg/dl within three days after contrast exposure. The primary end point was the incidence of CIN. The secondary end point was a 25% or greater reduction in eGFR.

RESULTSThere were no significant differences between the two groups with regard to age, gender, risk factors, laboratory results, medications and interventions. The incidence of CIN was 9.8% (13/132) in the treatment group and 20.3% (26/128) in the control group (P < 0.05). The secondary end point was 6.0% (8/132) in the treatment group and 16.4% (21/128) in the control group (P < 0.05).

CONCLUSIONThese results indicate the preventive effects of anisodamine against CIN in type 2 diabetics with renal insufficiency who are undergoing coronary angiography or angioplasty.
