Objective To study the X-ray signs of forearm and leg in skeletal fluorosis and its diagnostic value,aim at finding the easy examination parts.Methods One thousand four hundred and forty subjects were examined using developed shield,darkroom and other portable dedicated device combined with a small X-ray machine.A total of 384 cases were diagnosed skeletal fluorosis.All patients were divided into different groups and the time,degree and range of X-ray to the forearm and calf elbow,knee,and long bone were compared.Results The X-ray change in the forearm elbow was earlier than that of the leg knee,and trabecular bone change was the earliest indicator,197 cases and 157 cases,respectively,and the difference was statistically significant (x2 =28.006,P ＜ 0.01).Membrane ossification of forearm backbone was earlier than that of the leg,and most of them were degree Ⅰ photos,213 cases and 126 cases respectively.The difference was statistically significant (x2 =17.626,P ＜ 0.01).The direction of the interosseous membrane ossification was from the forearm radius to the ulna,then to the fibula and tibia,and was accompanied by changes in the aggravation of forearm.A variety of indicators were observed,especially the membrane ossification in bone and joint trabecular bone and the long bone was the most active,and the forearm was more sensitive,obviously than that of the calf.Conclusion In the X-ray screening or detection of endemic fluorosis,the forearm radiography is a simple,economical,and effective diagnostic method.

OBJECTIVETo investigate the clinical manifestations, pathological characteristics, and treatments of urothelial-type mucinous adenocarcinoma of the prostate (UMAP).

METHODSWe reported a case of UMAP, reviewed relevant literature, and analyzed the clinicopaothological features, diagnosis, treatment, and prognosis of the disease.

RESULTSThe patient was a 60-year-old male and underwent transurethral resection of the prostate for dysuria. Postoperative pathology indicated mucinous adenocarcinoma and sigmoidoscopy revealed no primary colon cancer. Immunohistochemical staining showed the negative expressions of PSA and P504s and positive expressions of CK7, CK34 β E12, CK20, and CDX2. Thus UMAP was confirmed and treated by intensity-modulated radiotherapy. Then the patient was followed up for 30 months, which showed desirable therapeutic result, with neither local progression nor distant metastasis.

CONCLUSIONUMAP has a bad prognosis and its diagnosis depends on pathological and immunohistocchemical examinations. It responds well to radical prostatectomy but is not sensitive to endocrine therapy. Radiotherapy can be considered for those who are not fit to receive radical prostatectomy.

Objective To evaluate the clinical efficacy and safety of compound polymyxin B ointment combined with desonide cream for the treatment of subacute or chronic eczema. Methods A multicenter, randomized, double?blind, parallel?group, controlled clinical study was conducted. Totally, 144 patients with subacute eczema and 144 patients with chronic eczema were enrolled into this study, and both randomly and equally divided into the test group and control group. The test group and control group firstly topically applied compound polymyxin B ointment and its vehicle respectively, then both topically applied desonide cream 3 hours later. The drugs or vehicle were applied twice a day in all the patients. Patients′ symptoms and signs (including degree of itching, inflammation, erosion/exudation and infiltration/thickening, as well as area of target lesions) were evaluated, and the time to onset and duration of itching?alleviating effect were recorded. The clinical efficacy and safety of treatments were analyzed and compared between the test group and control group. Results The total symptom and sign scores significantly decreased to different extents on days 7 and 14 in the test group(subacute eczema patients:6.09 ± 2.78 and 3.68 ± 3.18 vs. 13.44 ± 1.66; chronic eczema patients: 6.56 ± 2.68 and 4.38 ± 3.27 vs. 12.96 ± 1.16)and control group(subacute eczema patients:8.26 ± 3.17 and 5.28 ± 4.05 vs. 13.60 ± 1.75;chronic eczema patients: 8.84 ± 2.90 and 6.25 ± 3.78 and vs. 12.64 ± 1.18)compared with those at baseline. Moreover, the total symptom and sign score of patients with subacute or chronic eczema was significantly lower in the test group than in the control group on days 7 and 14(all P<0.05). A significant increment was observed in the degree of decrease in scores for itch, infiltration/thickening in patients with subacute eczema in the test group compared with that in the control group(all P<0.01), as well as in scores for itch, infiltration/thickening and area of target lesions in patients with chronic eczema in the test group compared with those in the control group (all P < 0.05). In addition, patients with subacute eczema in the test group showed significantly shorter onset and longer duration of itching?alleviating effect than those in the control group(both P<0.05). The time to onset of itching?alleviating effect was also significantly shorter in patients with chronic eczema in the test group than in those in the control group(P<0.000 1), but there was no significant difference in the duration of it between the two groups of patients with chronic eczema. Clinicians and patients were both more satisfied with therapeutic effects in the test group than in the control group(all P<0.05). Conclusions Topical compound polymyxin B ointment can increase the efficacy of topical desonide cream for the treatment of subacute or chronic eczema, especially subacute eczema. Compound polymyxin B ointment also shows a favorable therapeutic effect on itching and infiltration/thickening in patients with eczema.

OBJECTIVETo study the imprinting status of genetic imprinted gene PEG10 (perternally expressed gene 10) in human hepatocellular carcinoma (HCC) tissues and liver cancer cell lines.

METHODSGenomic DNA was extracted from 20 HCC tissues and its adjacent tissues, 15 normal liver tissues, 5 liver cancer cell lines (PLC/PRF/5, smmc-7721, HepG2, Hep3B, SK-HEP-1) and 2 normal human liver cell lines (changliver, HL7702). The DNA fragments containing single nucleotide polymorphism (SNP) site of PEG10 were amplified by polymerase chain reaction (PCR) and the genotype of samples was detected by DNA sequencing. Total RNA was extracted from heterozygous samples, the imprinting status and expression level of PEG10 were evaluated by quantitative real time reverse transcription-polymerase chain reaction (qRT-PCR) and DNA sequencing.

RESULTSIt was found that 16/40 of HCC and its adjacent tissues were heterozygous, 3/15 of normal liver tissue were heterozygous. A site of heterozygous mutation was found in HepG2 cells by DNA sequencing. The other liver tissues and cell lines were all homozygous. PEG10 was biallelically expressed and showed loss of imprinting (LOI) in 82.4% (14/17) liver cancer samples (16 HCC tissues and HepG2), however it was a monoallelic expression and showed genomic imprinting in17.6% (3/17) liver cancer samples. In HCC, the expression levels of PEG10 were increased apparently, but it was negative expressed in cancer adjacent tissues and normal liver tissues. Expression levels of PEG10 were not significantly different between imprinted HCC tissues and HCC tissues with LOI (t = 1.311, P value is more than 0.05).

CONCLUSIONPEG10 imprinting is lost in a majority of HCC and no correlation exists between the imprinting status of PEG10 and its expressions in HCC tissues.

This study was aimed to explore the expression of 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) in 3 different lymphoblastic cell lines with relation to their glucocorticoid (GC) sensitivity. The 11β-HSD2 expressions in acute lymphoblastic leukemia Jurkat cells, lymphoma Daudi and Raji cells, and peripheral blood T cells of a healthy volunteer were analyzed by real time PCR and Western blot. Glucocorticoid (GC)-induced apoptosis in 3 different cell lines was detected by flow cytometry. Cell growth in Jurkat cells treated with cortisol was analyzed by trypan blue dye exclusion. Flow cytometry was performed to observe GC-induced apoptosis in Jurkat cells treated by combination of GC with 11β-HSD2 inhibition 18β-glycyrrhetinic acid (18β-GA). The results demonstrated that 11β-HSD2 highly expressed in Jurkat cells, but not in Daudi, Raji cells and normal blood T cells. Compared to Daudi and Raji cells, Jurkat cells were more resistant to GC-induced apoptosis. Furthermore, the inhibition of 11β-HSD2 by 18β-GA resulted in increased cellular sensitivity to GC as shown by elevated induction of apoptosis. it is concluded that 11β-HSD2 is at least partly responsible for GC resistance in Jurkat cells. 11β-HSD2 may be a potential target for reduction of GC-resistance in therapeutic applications.

Objective:To investigate the implementation status of appropriate technique of Traditional Chinese Medicine (TCM) in the perioperative period in China using questionnaires.Methods:From May to June 2022, the questionnaire designed by ourselves was sent to anesthesiologists participating in the survey through the WeChat platform nationwide, and the system automatically recorded the survey.Results:A total of 6 230 anesthesiologists participated in the questionnaire survey, there were 6 160 valid questionnaires, with an effective rate of 98.88%.The anesthesiologists participating in the questionnaire survey were distributed in 16 provincial administrative regions in China, of which the rate from tertiary hospitals was 32.59%, the rate from secondary hospitals was 67.41%, and the application rate of TCM appropriate techniques in the perioperative period was 9.8%.The application rate of TCM appropriate techniques in the perioperative period was higher in tertiary hospitals than in secondary hospitals (9.51% vs. 6.31%, P<0.05), and the application rate was significantly higher in TCM hospitals than in integrated Chinese and Western Medicine hospitals and Western medicine general hospitals (26.15% vs.7.26% vs. 2.49%, P<0.05). Among the provinces participating in the survey, Guangdong Province had the highest application rate of TCM appropriate techniques in the perioperative period (13.60%). In the anesthesiologists carried out TCM appropriate techniques in the perioperative period, the highest application rate of TCM appropriate techniques in non-drug therapy was 59.0%, and the highest application rate in abdominal surgery was 47.4%, and most anesthesiologists (68.1%) selected TCM appropriate techniques according to the type of surgery in patients.Anesthesiologists who applied TCM appropriate techniques in the perioperative period believed that TCM appropriate technique cloud reduce the development of nausea and vomiting in the perioperative period (66.8%), alleviate perioperative pain (54.8%), promote the recovery of perioperative gastrointestinal function (49.8%), and reduce the development of perioperative neurocognitive disorders (47.0%). The main reasons for the lack of TCM appropriate techniques in the perioperative period were the lack of standardized technical training and relevant guidelines (87.11%), the lack of relevant charging items (58.30%), the technical level of operators (46.20%), the lack of support by surgeons (43.40%), and the non-cooperation of patients (27.10%). Conclusions:At present, the application rate of TCM appropriate techniques in the perioperative period is generally low, and the application rate varies greatly among different provinces and hospitals of different levels.Publicity should be expanded through multiple channels, various forms of technical training should be carried out, the implementation plan and guidelines of TCM appropriate technologies should be continuously optimized, and the promotion and application of TCM appropriate techniques in the perioperative period should be strengthened.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation with midnight-noon ebb-flow acupoint selection on postoperative delirium (POD) in the patients undergoing radical resection of colorectal cancer.Methods:A total of 93 patients of either sex, aged ≥18 yr, with body mass index <30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ, scheduled for elective radical resection of colorectal cancer under general anesthesia, were divided into 3 groups ( n=31 each) using a random number table method: control group (group C), common TEAS group (group CT), and midnight-noon ebb-flow acupoint selection TEAS group (group MT). The patients received TEAS at bilateral Hegu, Quchi and Shousanli acupoints at 6: 00 in group MT and at 18: 00 in group CT on the day of operation and 1-3 days after surgery, with a frequency of 2/100 Hz, disperse-dense waves, intensity the maximum current that could be tolerated, and each TEAS lasted for 30 min. In group C, only the electrodes were pasted at the same acupoints without electric current at 6: 00 am. The POD was evaluated by the Confusion Assessment Method (CAM) at 1, 3 and 5 days after operation (T 1-3). Blood samples were collected for determination of serum interleukin-1beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α) concentrations at 1 day before operation and at T 1. The time to first flatus and defection and adverse reactions after operation were recorded. Results:Compared with group C, the CAM scores at each time point and incidence of POD were significantly decreased, the concentrations of IL-1β, TNF-a and IL-6 in serum were decreased at T 1, the time to the first flatus and defecation was shortened, and the incidence of abdominal distension after surgery was decreased in MT and CT groups ( P<0.05). Compared with group CT, the CAM scores at T 3 and incidence of POD were significantly decreased, the concentrations of TNF-a and IL-6 at T 1 were decreased, and the time to first defecation after operation was shortened in group MT ( P<0.05). Conclusions:TEAS guided by midnight-noon ebb-flow acupoint selection provides better efficacy than common TEAS in decreasing the risk of POD in the patients undergoing radical resection of colorectal cancer, which is helpful for the early postoperative recovery of patients.
