ABSTRACT: Meningiomas are the most common primary intracranial neoplasm with diverse pathological types and complicated clinical manifestations. The fifth edition of the WHO Classification of Tumors of the Central Nervous System (WHO CNS5), published in 2021, introduces major changes that advance the role of molecular diagnostics in meningiomas. To follow the revision of WHO CNS5, this expert consensus statement was formed jointly by the Group of Neuro-Oncology, Society of Neurosurgery, Chinese Medical Association together with neuropathologists and evidence-based experts. The consensus provides reference points to integrate key biomarkers into stratification and clinical decision making for meningioma patients.

BACKGROUND: Ankylosing spondylitis (AS) is a common chronic progressive rheumatic disease. The aim of this study was to explore factors influencing abnormal bone mineral density (BMD) in young and middle-aged patients with AS. METHODS: From July 2014 to August 2018, hospitalized patients with AS and health examinees in the health examination center of our clinics, ranging in age from 20 to 50 years, were monitored. The BMD of the lumbar spine and femoral neck of AS patients and those of a healthy control group were measured using dual-energy X-ray absorption. The BMDs of AS patients were compared with respect to age, course of disease, iritis, smoking habits, sex, height, weight, body mass index (BMI), medication use, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), platelet volume, platelet count, uric acid (UA), alkaline phosphatase (AKP), and calcium ion levels. Single-nucleotide polymorphisms (SNPs) related to BMD were screened using genome-wide association analysis. RESULTS: There was no statistical difference in the proportion of abnormal bone masses between the different body parts. The BMD of all bones in AS patients was lower than that in healthy controls (P < 0.05). Additionally, BMD was correlated with serum calcium and CRP in AS patients (P < 0.05), but not with age, platelet volume, platelet count, ESR, UA, AKP, height, weight, and BMI. The incidence of abnormal bone mass in AS patients was correlated with sex (P < 0.05), but not with medication use, iritis, or smoking. BMD of the lumbar spine in AS patients did not correlate linearly with the course of the disease, but BMD of the femoral neck correlated linearly with the course of the disease (P < 0.05). BMD was correlated with multiple SNPs in patients with AS. Lumbar BMD was correlated with rs7025373 and rs7848078. Femoral head BMD was correlated with 3:102157365, 3:102157417, rs1252202, rs1681355, rs3891857, rs7842614, and rs9870734, suggesting that genetic factors play a role in BMD in patients with AS. CONCLUSIONS The proportion of abnormal bone mass in AS patients was higher than that in healthy individuals of the same age. The factors related to BMD in patients with AS are gender, CRP, and blood calcium. The BMD of the femoral neck of AS patients decreases with the course of the disease, but BMD of the lumbar spine is not related to the course of the disease. BMD in AS patients is associated with multiple SNPs.

The clinical predictive factors for malignant testicular histology remain unclear because of the low prevalence. Therefore, the aim of this study was to investigate predictors of malignant histology for testicular masses and decide more testis-sparing surgeries before surgery. This retrospective study enrolled 325 consecutive testicular mass patients who underwent radical orchiectomy (310/325) or testicular preserving surgery (15/325) from January 2001 to June 2016. The clinicopathological factors, including tumor diameter, cryptorchidism history, ultrasound findings, serum alpha-fetoprotein, and human chorionic gonadotropin (HCG) levels, were collected retrospectively for statistical analysis. A predictive nomogram was also generated to evaluate the quantitative probability. Among all patients, 247 (76.0%) were diagnosed with a malignant testicular tumor and 78 (24.0%) with benign histology. Larger tumor diameter (per cm increased, hazard ratio [HR] = 1.284, P = 0.036), lower ultrasound echo (HR = 3.191, P = 0.001), higher ultrasound blood flow (HR = 3.320, P < 0.001), and abnormal blood HCG (HR = 10.550, P < 0.001) were significant predictive factors for malignant disease in all testicular mass patients. The nomogram generated was well calibrated for all predictions of malignant probability, and the accuracy of the model nomogram measured by Harrell's C statistic (C-index) was 0.92. According to our data, the proportion of patients who underwent radical orchiectomy for benign tumors (24.0%) was much larger than generally believed (10.0%). Our results indicated that the diameter, ultrasonic echo, ultrasonic blood flow, and serum HCG levels could predict the malignancy in testicular mass patients.

Through the traditional Chinese medicine inheritance platform system, with the help of medical records, Ye Tianshi and Wu Jutong's medication characteristics for summer heat sickness were analyzed, the laws of the two people's medication were summarized, and the similarities and differences between the two were explored to explore the relationship. As a result, it was found that both of them recognized the relationship between summer heat and wetness, and Wu Jutong believed that "wind" was also an important pathogenic factor. Both of the patients were treated with cold medicine and warm medicine. They used mostly bitter, sweet, pungent taste and lungs, spleen, stomach, and heart meridian are the main components; two are commonly used Armeniacae Semen Amarum, Talcum, Rehmanniae Radix, Ophiopogonis Radix, Pinelliae Rhizoma and other drugs, Ye Tianshi use Scrophulariae Radix, Tetrapanacis Medulla, Coicis Semen and other drugs more, Wu Jutong use Gypsum Fibrosum, Sojae Semen Praeparatum, Menthae Haplocalycis Herba and other drugs more; at the same time, a combination of two high-frequency medicines used by two people has been excavated, and a new prescription has been deduced to provide a reference for further understanding and treatment of summer diseases.

Occupational carbon monoxide (CO) poisoning related to diesel motor fumes in an air-raid shelter (ARS) was first identified in Jinan City, China, in June 2015. A total of 17 cases were identified, including 14 possible cases of firemen and 3 confirmed cases of water channel clean-up workers. The overall attack rate (AR) of firemen was 42% (14/33). The firemen had a significantly higher AR with a longer exposure and more protracted time of rescue in the ARS (P < 0.05). All the cases stated that they did not realize the potentially high level of exposure to CO in the ARS. CO poisoning posed a risk to both patients and service providers. Occupational safety and health education should be promoted and enforced in all workplaces where CO sources exist.

OBJECTIVETo evaluate the postoperative outcomes of preserving the left colonic artery during laparoscopic anterior resection for rectal cancer.

METHODSThe clinicopathologic data of 91 rectal cancer patients (pathologic Stage II) undergoing laparoscopic anterior resection was retrospectively analyzed. During the surgeries, the left colonic artery was preserved in 40 patients (preserved group) and ligated in 51 patients (unpreserved group). The operating time, intraoperative blood loss, time to first flatus and defecation, duration of postoperative abdominal distension and pain, number of retrieved lymph nodes, ileum fistulation and anatomical leakage rate were compared between the two groups.

RESULTSThe surgeries were completed in all the 91 patients laparoscopically without conversion. There was no intraoperative complications including rectal perforation, injury to vessel or ureter in either group. The operating time, blood loss and number of retrieved lymph nodes were similar between the groups (P>0.05). Three patients in preserved group and 5 in ligation group received preventive ileum fistulation due to low rectal cancer. Anatomical leakage occurred in three patients of unpreserved group. The average duration of postoperative abdominal distension and pain was 2.14∓0.35 days in preserved group and 3.15∓0.42 days in ligation group. The time to first flatus and defecation was 37.15∓12.62 h and 3.16∓0.52 days in preserved group and 62.25∓11.75 h and 4.25∓0.75 days in ligation group. Postoperative hospital stay was 4.54∓0.42 days in preserved group and 6.23∓0.51 days in ligation group. Total hospitalization cost in the two groups was 34 525.32∓1206.36 Yuan and 41 215∓1051.32 Yuan, respectively. Significant differences were found the in duration of postoperative abdominal distension and pain, postoperative hospital stay, and total cost between the two groups (P<0.05).

CONCLUSIONDuring laparoscopic anterior resection for rectal cancer, preserving the left colonic artery effectively ensures the blood supply to the anastomosis and the remaining descending colon to promote the recovery of the patients after surgery.

Ginkgo diterpene lactones meglumine injection (GDLI) is a commercially available product used for neuroprotection. However, the pharmacokinetic properties of the prototypes and hydrolyzed carboxylic forms of the primary components in GDLI, i.e., ginkgolide A (GA), ginkgolide B (GB), and ginkgolide K (GK), have never been fully evaluated in beagle dogs. In this work, a simple, sensitive, and reliable method based on ultra-fast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS) was developed, and the prototypes and total amounts of GA, GB, and GK were determined in beagle dog plasma. The plasma concentrations of the hydrolyzed carboxylic forms were calculated by subtracting the prototype concentrations from the total lactone concentrations. For the first time, the pharmacokinetics of GA, GB, and GK were fully assessed in three forms, i.e., the prototypes, the hydrolyzed carboxylic forms, and the total amounts, after intravenous administration of GDLI in beagle dogs. It was shown that ginkgolides primarily existed in the hydrolyzed form in plasma, and the ratio of hydrolysates to prototype forms of GA and GB decreased gradually to a homeostatic ratio. All of the three forms of the three ginkgolides showed linear exposure of AUC to the dosages. GA, GB, and GK showed a constant half-life approximately 2.7, 3.4, and 1.2 h, respectively, which were consistent for the forms at three dose levels (0.3, 1.0, and 3.0 mg·kg) and after a consecutive injection of GDLI for 7 days (1.0 mg·kg).

In order to investigate whether Yinchenhao decoction (YCHD) attenuates hepatic fibrogenesis in the bile duct ligation (BDL) model via recovering and restoring the self-regulation and balance of the renin-angiotensin system (RAS), 33 specific-pathogen-free (SPF) male Sprague-Dawley rats with common BDL and scission were randomly divided into five groups as follows: G1, the sham group (n=4); G2, BDL 7-day group (n=5); G3, BDL+YCHD 430 mg/mL (n=8); G4, BDL+losartan 0.65 mg/mL (ARB group, n=8); G5, model group (BDL without any treatment, n=8). YCHD and losartan (10 mL·kg(-1)·day(-1)) were given by gastric gavage for 16 days following BDL in G3 and G4 groups, respectively. The effect of YCHD on liver fibrosis and the detailed molecular mechanisms were assessed by liver function including total bilirubin (TBIL), direct bilirubin (DBIL), indirect bilirubin (IDBIL), alanine aminotransferase (ALT), and aspartate aminotransferase (AST). Histological changes were observed by transmission electron microscopy (TEM) and Masson trichrome staining. Western blotting was used to detect the protein expression level of the renin-angiotensin system (RAS) components including angiotensin converting enzyme (ACE), angiotensin II type 1 receptor (AT1R), ACE2, angiotensin II (AngII) as well as transforming growth factor β1 (TGFβ1). The experimental data were analyzed by principle component analytical method of pattern recognition. The results showed that biochemically, serum TBIL, DBIL, IDBIL, ALT and AST levels were markedly increased following BDL as compared with the sham group (P<0.05). Serum TBIL, IDBIL and DBIL levels in G3 group were dramatically decreased as compared with G5 and G4 groups (P<0.05). Serum AST level in G3 was significantly lowered than in G5 group (P<0.05), but there was no significant difference in ALT among G3, G4 and G5 groups (P>0.05). Histologically, livers in G3 group showed less hepatocytes necrosis, less bile duct hyperplasia and less collagen formation than in G4 and G5 groups. The protein expression levels of ACE2, ACE, AngII, AT1R and TGFβ1 in G2, G3 and G4 groups were significantly higher than in sham group (P<0.05), and lower than in G5 group (P<0.05). However, the differences among G2, G3 and G4 groups were not significant (P>0.05). ACE2 protein expression in G3 group was significantly higher than in G2 group (P<0.05) and there was no significant difference in comparison with G4 group (P>0.05). Moreover, the protein expression of TGFβ1 in G3 group was significantly lower than in G5 and G4 groups (P<0.05). Our findings suggest that the antifibrotic effects of YCHD may be associated with the decreased classical RAS pathway components and TGFβ1 downexpression so as to recover and rebuild self-regulation of the RAS by elevating the protein expression of ACE2.

OBJECTIVETo explore the efficacy and safty of sorafenib in Child-Pugh class B to class C hepatocellular carcinoma (HCC).

METHODSIn this three-center open-label study from November 2011 to May 2013, we randomly assigned 189 patients with advanced Child-Pugh class B or C HCC patients into two groups, one group with 95 patient to receive sorafenib (400 mg a time, twice a day) and the other group with 94 patients to receive best supportive care. The primary end points were progression-free survival and overall survival.

RESULTSThe median progression-free survival was 2.2 months and 1.9 months in the sorafenib group and best supportive care group respectively (Hazard ratio in the sorafenib group, 0.55; 95% confidence interval, 0.40-0.75; P=0.002). The median overall survival was 4.0 months and 3.5 months in the sorafenib group and best supportive care group respectively (Hazard ratio in the sorafenib group, 0.48; 95% confidence interval, 0.35-0.68; P<0.001). The main adverse effect of sorafenib was rash and acne of the skin (in 51.7% patients). The incidences of severe rash, diarrhea, and dry skin were 5.6%, 5.6%, and 2.2% in the sorafenib group. One patient reached partial response in the sorafenib group.

CONCLUSIONSSorafenib is safe in patients with liver function impaired advanced HCC. It is effective in terms of progression-free survival and overall survival compared with best supportive care. Liver functions are the important predictive factors.
