ABSTRACT

Objective:To investigate the practicality and safety of performing a radical prostatectomy(RP)shortly after the diagnosis of prostate cancer using a combination of prostate targeted biopsy and intraoperative frozen section.Methods:Prospective enrollment was conducted for patients suspected of having prostate cancer based on abnormal prostate specific antigen(PSA)levels.The inclusion criteria for the study were as follows: patients aged 80 years or younger with an ECOG score of 1 or lower.Prior to biopsy, patients underwent both prostate magnetic resonance imaging(MRI)and prostate specific membrane antigen positron emission tomography/computed tomography(PSMA PET/CT)to determine the likelihood of prostate cancer with clinical stages within T 2-3aN 0M 0.In order to be included in the study, patients must agree to receive RP after their prostate cancer diagnosis has been confirmed by biopsy.All enrolled patients underwent a targeted prostate biopsy, consisting of 1-2 cores.These specimens were then examined through frozen section analysis.For patients diagnosed with prostate cancer through intraoperative frozen section pathology, RP was immediately performed.In this study, transperineal prostate targeted+ systematic biopsy was utilized for patients with undiagnosed prostate cancer.Additionally, routine pathological examination of specimens was conducted.The study analyzed the baseline data, surgical conditions, pathological results, and follow-up information of patients in a descriptive manner. Results:Seven patients, ranging in age from 54 to 77 years with a mean age of 66.7 years, were enrolled in the study.Their mean PSA level was 12.668 μg/L, ranging from 4.359 to 22.195 μg/L.Of these patients, 4 had a PI-RADS score of 4 and 3 had a score of 5.The maximum diameter of the index lesion was 1.3 cm, ranging from 0.5 to 2.2 cm.PSMA PET/CT scores were 4 in 1 case and 5 in 6 cases.The index lesions detected by PSMA PET/CT were consistent with those detected by MRI, and the maximum standardized uptake value(SUVmax)was 15.7, ranging from 5.3 to 39.4.Prostate cancer was diagnosed through targeted biopsy and intraoperative frozen section pathology.Four cases had a Gleason score of 3+ 3=6, while one case had a Gleason score of 3+ 4=7, another had a score of 4+ 3=7, and the last had a score of 4+ 4=8.All patients underwent RP treatment immediately after the prostate cancer diagnosis.Only one patient had slight adhesion at the apex of the prostate, while the other six patients were evaluated by surgeons as having no obvious adhesion at the apex.All surgeries were completed successfully, with a mean operation time of 149.7(ranging from 108 to 255)minutes.After RP, whole mount pathology results indicated that all cases were prostate adenocarcinoma, with a Gleason score of 3+ 4=7 in four cases and 4+ 3=7 in three cases.The pathological stages were pT2 in three cases and pT3a in four cases, with five cases having negative surgical margins and two cases with positive surgical margins.During the study, all patients were monitored for a period of 5.4 months(ranging from 3 to 7 months)and no complications of Clavien Dino≥Ⅰ were observed.PSA levels were measured at 6 weeks and 3 months after surgery, with readings of 0.020 μg/L(ranging from 0 to 0.079 μg/L)and 0.016 μg/L(ranging from 0 to 0.087 μg/L), respectively.No hormonal therapy or radiotherapy was administered during this time.Four patients were able to recover from urinary continence.Conclusions:Based on a combination of MRI and PSMA PET/CT, it is both safe and feasible to promptly perform RP following the diagnosis of prostate cancer through targeted biopsy for index lesions, along with intraoperative frozen section.

ABSTRACT

Objective:To explore the association between body mass index (BMI) and the incidence of thyroid nodules, the clinical characteristics and efficacy evaluation of differentiated thyroid cancer (DTC), respectively.Methods:Clinical data of 1 375 healthy people (1 031 males, 344 females, age: (43.5±10.6) years) who underwent routine physical examination (PE) and 1 450 patients (490 males, 960 females, age: (44.3±12.4) years) with medium-high risk DTC in Tianjin Medical University General Hospital from April 2016 to July 2020 were analyzed retrospectively. PE and DTC patients were classified into underweight group (BMI<18.5 kg/m 2), normal weight group (18.5≤BMI<24.0 kg/m 2), overweight group (24.0≤BMI<28.0 kg/m 2) and obesity group (BMI≥28.0 kg/m 2) respectively. χ2 test was employed to analyze the relation between BMI and thyroid nodules (with/without), BMI and clinical characteristics and efficacy evaluation of DTC, respectively. Logistic regression analysis was used to analyze the independent risk factors for the occurrence of thyroid nodules and the aggressiveness of DTC. Results:Among PE, there were 779 cases with nodules, and 596 cases without nodules. Comparing with those without nodules, more overweight and obese were found in PE cases with nodules (42.1%(328/779) vs 37.2%(222/596), 24.5%(191/779) vs 20.5%(122/596); χ2=13.42, P=0.004). Higher risk of developing thyroid nodules was related with older age and lower thyroid stimulating hormone (TSH) level (odds ratio ( OR): 1.044, 0.919, 95% CI: 1.029-1.060, 0.845-0.999; P<0.001, P=0.046). People with high-risk nodules were more likely to be obese than those with intermediate and lower risk nodules (5/15 vs 24.3% (186/764); χ2=21.11, P<0.001). Among 1 450 DTC patients, comparing with patients with normal weight, patients in the overweight and obesity groups were more likely to have central regional lymph node metastasis ( OR: 1.418, 1.427, 95% CI: 1.075-1.870, 1.044-1.952; P values: 0.013, 0.026), and patients in obese group were with greater risk of lesions being bilateral ( OR=0.696, 95% CI: 0.519-0.934; P=0.016). BMI was not related with the efficacy evaluation of DTC ( χ2=9.13, P=0.425). Conclusions:The incidence of thyroid nodules in people with high BMI is higher. DTC patients with high BMI may have more aggressive incidence. But BMI has no correlation with the efficacy evaluation of DTC patients after treatment.

ABSTRACT

Objective:To study whether male was the risk factor for prognosis of patients with differentiated thyroid cancer (DTC) after 131I treatment based on propensity score matching (PSM) method. Methods:From April 2016 to January 2021, 1 677 patients (age: 11-84 (43.9±12.5) years) with DTC who underwent total thyroidectomy and received 131I treatment in Tianjin Medical University General Hospital were retrospectively enrolled and patients were divided into male group ( n=546) and female group ( n=1 131). The evaluation results of patients were divided into excellent response (ER), indeterminate response (IDR), biochemical incomplete response (BIR) and structural incomplete response (SIR). Among them, ER and IDR were divided into good prognosis group, and BIR and SIR were divided into poor prognosis group. The PSM method was adopted to process all data to reduce the influence of data bias and confounding variables. χ2 test was used for data analysis. Multivariate logistic regression was used to analyze the risk factors affecting prognosis, and ROC curve was used to analyze the relationship between stimulated thyroglobulin (sTg) level and poor prognosis. Results:Before PSM, the proportion of male patients with poor prognosis was significantly higher than that of female patients (21.2%(116/546) vs 14.0%(158/1 131); χ2=17.53, P=0.001). After PSM, there was no difference in the proportion of poor prognosis between male and female groups (19.9%(107/537) vs 15.6%(84/537); χ2=5.43, P=0.143). Multivariate logistic regression analysis showed that male (odds radio ( OR)=1.439 (95% CI: 1.016-2.038), P=0.040), high T stage(T3+ T4 stage)( OR=1.816 (95% CI: 1.273-2.590), P=0.001), N1b stage ( OR=1.766 (95% CI: 1.233-2.530), P=0.002), M1 stage ( OR=9.833 (95% CI: 3.190-30.309), P<0.001) and sTg level ( OR=1.035 (95% CI: 1.029-1.042), P<0.001) were risk factors for poor prognosis before PSM, while high T stage (T3+ T4 stage)( OR=1.870 (95% CI: 1.212-2.886), P=0.005), M1 stage ( OR=8.993 (95% CI: 2.434-33.225), P=0.001), sTg level ( OR=1.040 (95% CI: 1.030-1.049), P<0.001) were still risk factors, and N1b stage ( OR=1.459 (95% CI: 0.938-2.270), P=0.094), male ( OR=1.383 (95% CI: 0.912-2.096), P=0.127) were no longer risk factors for poor prognosis after PSM. ROC curve analysis showed that the cut-off value of sTg was 10.25 μg/L, with the sensitivity of 81.0%(222/274) and the specificity of 84.2%(1 181/1 403). Conclusions:After reduction of selection bias by PSM, male is no longer a risk factor for prognosis after 131I treatment of DTC. In addition, high T stage(T3+ T4 stage), M1 stage and sTg≥10.25 μg/L were risk factors for poor prognosis.

ABSTRACT

Objective:To investigate the clinical characteristics and prognosis of cryptococcal meningitis patients with anti-granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies.Methods:A total of 216 non-acquired immunodeficiency syndrome (AIDS) related cryptococcal meningitis cases with positive cultures of Cryptococcus, hospitalized at Huashan Hospital, Fudan University during January 2014 and December 2021, were retrospectively included. The serum anti-GM-CSF autoantibodies were detected by enzyme linked immunosorbent assay, and the clinical characteristics and prognosis were compared between patients with and without anti-GM-CSF autoantibodies. Statistical comparisons were mainly performed using the chi-square test or Fisher′s exact test. Cox proportional-hazards model was used to analyze the risk factors associated with prognosis. Results:Among 216 enrolled patients, 23 patients were positive of anti-GM-CSF autoantibodies, with a positive rate of 10.6%. Among 23 patients, seven cases were infected with Cryptococcus gattii, and 16 cases were infected with Cryptococcus neoformans. In the group with positive anti-GM-CSF autoantibodies, 30.4%(7/23) of the patients were infected with Cryptococcus gattii, which was higher than that of 1.6%(3/193) in the group with negative anti-GM-CSF autoantibodies, and the difference was statistically significant ( χ2=38.82, P<0.001). In the group with positive anti-GM-CSF autoantibodies, 30.0% (6/20) had mass lesions with a diameter greater than three centimeters in the lungs, and the one-year all-cause mortality rate was 50.0% (10/20), which were both higher than those of 3.4%(5/145) and 16.1% (29/180) in the negative group, respectively. The differences were both statistically significant (both Fisher′s exact test, P<0.01). Age≥60 years (hazard ratio ( HR)=4.146, P=0.002), predisposing factors ( HR=3.160, P=0.021), epilepsy ( HR=6.129, P=0.002), positive anti-GM-CSF autoantibodies ( HR=2.675, P=0.034), white blood cell count of cerebrospinal fluid (CSF)<100 ×10 6/L ( HR=2.736, P=0.039), the titers of cryptococcal capsular polysaccharide antigen of CSF≥1∶1 280 ( HR=4.361, P=0.009) were independent risk factors for one-year all-cause mortality in patients with cryptococcal meningitis. Conclusions:In non-AIDS related cryptococcal meningitis patients, the positive rate of serum anti-GM-CSF autoantibodies is as high as 10.6%. Patients with anti-GM-CSF autoantibodies could be infected with both Cryptococcus neoformans and Cryptococcus gattii, and they have higher proportion of lung mass lesions than patients with negative anti-GM-CSF autoantibodies. The one-year survival rate decreases significantly in patients with anti-GM-CSF autoantibodies, which is an independent risk factor for the prognosis of cryptococcal meningitis.

ABSTRACT

Objective:To study the prevalence of skeletal fluorosis in drinking-water-borne endemic fluorosis areas in Inner Mongolia Autonomous Region (Inner Mongolia), and to provide reference for further prevention and treatment of skeletal fluorosis at this stage.Methods:From March to October 2019, a survey of skeletal fluorosis was carried out in all diseased villages of the eight diseased leagues (cities) in Inner Mongolia, including Alxa, Bayannur, Baotou, Ordos, Hohhot, Hulunbeier, Ulanqab and Xilingol. Permanent residents aged 18 years and above in the diseased villeges were investigated. Face to face questionnaires were used to collect the basic data of age, sex, epidemiological history, etc. of all subjects, and clinical examination of skeletal fluorosis was carried out. Drinking water samples were collected from residents for fluoride content testing.Results:A total of 123 166 residents aged 18 years and above were investigated, 1 781 cases of skeletal fluorosis were detected, and the detection rate was 1.45%. The degree of skeletal fluorosis was mild, accounting for 72.26% (1 287/1 781); the others were moderate and severe, accounting for 20.38% (363/1 781) and 7.36% (131/1 781), respectively. There were statistically significant differences in the detection rates of skeletal fluorosis among people of different water fluoride content, age, gender and regions (χ 2 = 565.96, 671.32, 4.38, 17 283.80, P < 0.05). Among them, the detection rates of skeletal fluorosis in water fluoride content > 4.0 mg/L, ≥56 years old and female population were relatively high, which were 5.21% (49/941), 2.26% (1 428/63 188) and 1.52% (905/59 555), respectively. The detection rates of skeletal fluorosis in Xilingol League and Baotou City were significantly higher, 25.48% (745/2 924) and 24.32% (225/925), respectively. Conclusion:The situation of skeletal fluorosis in drinking-water-borne endemic fluorosis areas in Inner Mongolia has been effectively controlled, but there are still relatively many patients with skeletal fluorosis in some areas, and further targeted prevention and control work is needed.

ABSTRACT

Objective To provide anatomical basis for clinical treatment of acromioclavicular joint dislocation by studying the morphology of coracoid process of human scapula. Methods A total of 500 patients with shoulder injury were selected from the Affiliated Hospital of Traditional Chinese Medicine of Southwest Medical University in Sichuan Province, and 300 patients were selected as subjects, including 159 cases of right shoulder and 141 cases of left shoulder. CT scan images and 3D reconstruction results of scapula of the subjects were collected. The basic morphological characteristics of coracoid process CT images of the subjects were observed, and the relevant parameters were measured, including the longest horizontal distance of the coracoid process tip and the thickness of the midpoint (cd, pp’), the distance from the upper part of the coracoid process scapula to the base and the thickness of the midpoint (mn, kk’). The distance from the apex of the coracoid process to the base of the coracoid process (ab), the longest horizontal distance of the recursion part of the coracoid process (ef), the distance of as (point s was the intersection of point a perpendicular to mn), the distance of hj (point h and j were the intersection of the base of the coracoid process and the recursion part respectively), and ik (point i was the intersection of point k perpendicular to mn and the coracoid process retraction). Results According to the morphological characteristics of coracoid process, they were divided into five types, including peanut 29. 7%; Short rod type accounted for 27. 4%; Melon seed type accounted for 12. 6%; Rod type accounted for 17. 0%; Wedge type accounted for 13. 3%. Through data comparison, it was found that the distance ef and distance hj on the left were larger than those on the right, P<0. 05. All types had statistical difference in comparison distance cd, P<0. 05. The melon seed type showed statistical differences with peanut type, wedge type, long stick type and short stick type in thickness pp’, distance ab and as of point p, P<0. 05. In the comparison of point K thickness kk’, there was statistical difference between melon seed type and other four types, P<0. 05. In the distance ab comparison, there was statistical difference between the short bar type and the other four types, P < 0. 05. Conclusion The study on the morphology of coracoid process can provide anatomical basis for clinical reconstruction of coracoid ligament to treat acromioclavicular joint dislocation.

ABSTRACT

Objective: To investigate the clinical characteristics, serogroups and antimicrobial resistance of invasive non-typhoid Salmonella infection in children at Xiamen. Methods: Retrospective cohort study. The clinical manifestations, treatment, prognosis, serogroups and antimicrobial resistance of 29 hospitalized children with invasive non-typhoid Salmonella infection confirmed by blood, cerebrospinal fluid, bone marrow and other sterile body fluids or deep pus culture at the Department of Infectious Diseases, the Department of Orthopedics and the Department of General Surgery in Xiamen Children's Hospital from January 2016 to December 2021 were analyzed. According to the clinical diagnosis criteria, the patients were divided into sepsis group and non-sepsis group (bacteremia and local suppurative infection). The inflammatory markers, serogroups distribution and drug resistance were compared between the two groups. Comparison between groups using Mann-Whitney U test and χ2 test. Results: Among the 29 cases, there were 17 males and 12 females, with an onset age of 14 (9, 25) months, and 10 cases (34%) of patients were younger than 1 year old, 15 cases (52%) under 1 to 3 years old, and 4 cases (14%) greater than or equal 3 years old. The onset time of 25 cases (86%) was from April to September. The diseases included 19 cases (66%) septicemia (2 of which were combined with suppurative meningitis), 10 cases (34%) non-sepsis group, including 7 cases bacteremia and 3 cases local suppurative infection (2 cases of osteomyelitis, 1 case of appendicitis with peritonitis). The clinical manifestations were fever in 29 cases (100%), diarrhea and abdominal pain in 18 cases (62%), cough and runny nose in 10 cases (34%). Eighteen cases (62%) were cured and 11 cases (38%) were improved by effective antibiotics treatment. C-reactive protein in sepsis group was significantly higher than that in non-sepsis group (25.2 (16.1, 56.4) vs. 3.4 (0.5, 7.5) mg/L, Z=-3.81, P<0.001).The serogroups of C, B and E were the most prevalent among non-typhoid Salmonella isolates, accounting for 10 cases (34%), 9 cases (31%) and 7 cases (24%) respectively. Antibacterial drug sensitivity test showed that the sensitivity rates of imipenem, ertapenem and piperaciratazobactam were all 100% (31/31), those of ceftazidime, ceftriaxone, and cefepime were 94% (29/31), 94% (29/31) and 97% (30/31) respectively. The drug resistance rates of ampicillin, ampicillin-sulbactam and trimethoprim-sulfamethoxazole were 51% (16/31), 48% (15/31) and 48% (15/31) respectively, those of cefazolin, cefotetan, tobramycin, gentamicin and amikacinwere all 100% (31/31). There were no significant differences in the drug resistance rates of ceftazidime, ceftriaxone, aztreonam, ampicillin-sulbactam, ampicillin, trimethoprim-sulfamethoxazole and ciprofloxacin between the sepsis group and the non-sepsis group (χ2=0.31,0.31,0.00,0.02,0.02,0.02,0.26, all P>0.05). Conclusions: Invasive non-typhoid Salmonella infection in children at Xiamen mainly occurred in infants younger than 3 years old.The main clinical manifestations are fever, abdominal pain and diarrhea. C-reactive protein can be served as the laboratory indicators for indicating sepsis. The third generation of cephalosporins is recommended as the first choice for treatment.

ABSTRACT

Objective: To investigate the clinicopathological features, and molecular genetic alterations of metaplastic thymoma (MT). Methods: A total of ten MT cases, diagnosed from 2011 to 2021, were selected from the Department of Pathology of Jinling Hospital, Nanjing University Medical School, Nanjing, China for clinicopathological and immunohistochemical (IHC) examination and clinical follow-up. Fluorescence in situ hybridization (FISH), next-generation sequencing (NGS), and YAP1 C-terminus (YAP1-CT) IHC were performed to detect YAP1::MAML2 fusions. Results: There were four males and six females, ranging in age from 29 to 60 years (mean 50 years, median 54 years). Microscopically, all tumors showed a typical biphasic morphology consisting of epithelial components and gradually or abruptly transitioning spindle cell components. The two components were present in varying proportions in different cases. Immunophenotypically, the epithelial cells were diffusely positive for CKpan, CK5/6 and p63. The spindle cells were diffusely positive for vimentin and focally positive for EMA. TdT was negative in the background lymphocytes. Ki-67 proliferation index was less than 5%. YAP1 and MAML2 break-apart FISH analyses showed that all ten cases had narrow split signals with a distance of nearly 2 signal diameters and may be considered false-negative. Using YAP1::MAML2 fusion FISH assays, abnormal fusion signals were observed in all the ten cases. NGS demonstrated YAP1::MAML2 fusions in all eight cases with adequate nucleic acids; in two cases the fusions were detected by DNA sequencing and in eight cases by RNA sequencing. All ten cases of MT demonstrated loss of YAP1 C-terminal expression in epithelioid cells. Conclusions: MT is a rare and low-grade thymic tumor characterized by a biphasic pattern and YAP1::MAML2 fusions. Break-apart FISH assays may sometimes show false-negative results due to the proximity of YAP1 and MAML2, while YAP1 C-terminal IHC is a highly sensitive and specific marker for MT. Loss of YAP1 C-terminal expression can also be used to screen YAP1::MAML2 fusions for possible MT cases.

ABSTRACT

Non-alcoholic fatty liver disease (NAFLD) is considered to be a manifestation of metabolic syndrome and has become one of the chronic diseases that endanger health around the world. There is still a lack of effective therapeutic drugs in clinical practice. Farnesoid X receptor (FXR) has been a popular target for NAFLD research in recent years. Fexaramine (Fex) is a potent and selective agonist of FXR, and its mechanism of action to improve NAFLD is unclear. Therefore, in this study, a mouse model of NAFLD was constructed using a high-fat, high-cholesterol diet and treated with Fex orally for 6 weeks. We evaluated the ameliorative effect of Fex on disorders of glucolipid metabolism in NAFLD mice, and preliminarily explored its potential mechanism of action. The animal experiments were approved by the Animal Ethics Committee of Shanghai University of Traditional Chinese Medicine (approval number: PZSHUTCM210913011). In this study, it was found that 100 mg·kg-1 Fex significantly inhibited body weight gain, alleviated insulin resistance, improved liver injury and lipid accumulation in NAFLD mice. The effect of Fex on the expression of hepatic intestinal FXR and its target genes in NAFLD mice was further examined. Analysis of serum and hepatic bile acid profiles and expression related to hepatic lipid metabolism. It was found that Fex could stimulate intestinal FXR, promote fibroblast growth factor 15 (FGF15) secretion, inhibit the expression of cytochrome P450 family 7 subfamily A member 1 (CYP7A1), the rate-limiting enzyme of bile acid synthesis in liver, regulate bile acid synthesis by negative feedback, and improve the disorder of bile acid metabolism. At the same time, Fex reduces liver lipid synthesis and absorption, increases fatty acid oxidation, thus improving liver lipid metabolism. This study shows that Fex can improve NAFLD by activating intestinal FXR-FGF15 signal pathway and regulating liver lipid metabolism.

ABSTRACT

OBJECTIVE@#To observe the effects of the Xingnao Kaiqiao (regaining consciousness and opening orifices) acupuncture on hemorrhagic transformation and limb motor function after intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in stroke patients.@*METHODS@#A total of 130 stroke patients after rt-PA thrombolytic were divided into an acupuncture group (58 cases, 1 case dropped off) and a non-acupuncture group (72 cases, 7 cases dropped off) according to whether they received acupuncture treatment. Propensity score matching (PSM) was used to match each group, with 38 patients in each group. The patients in the non-acupuncture group received rt-PA thrombolytic therapy and western medical basic treatment. In addition to the basic treatment, the patients in the acupuncture group received Xingnao Kaiqiao acupuncture at Shuigou (GV 26), bilateral Neiguan (PC 6), and ipsilateral Sanyinjiao (SP 6), Chize (LU 5), once a day for 14 days. The incidence of hemorrhagic transformation within 30 days after onset was compared between the two groups. The Fugl-Meyer assessment (FMA) score and activities of daily living (ADL) score were observed at baseline and 30 days, 6 months, 1 year after onset in the two groups. The disability rate at 6 months and 1 year after onset was recorded, and safety was evaluated in both groups.@*RESULTS@#The incidence of hemorrhagic transformation in the acupuncture group was 5.3% (2/38), which was lower than 21.1% (8/38) in the non-acupuncture group (P<0.05). At 30 days, 6 month, and 1 year after onset, the FMA and ADL scores of both groups were higher than those at baseline (P<0.01), and the scores in the acupuncture group were higher than those in the non-acupuncture group (P<0.01). The disability rate in the acupuncture group at 1 year after onset was 10.5% (4/38), which was lower than 28.9% (11/38) in the non-acupuncture group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05).@*CONCLUSION@#The Xingnao Kaiqiao acupuncture method could reduce the incidence of hemorrhagic transformation in stroke patients after intravenous thrombolysis with rt-PA, improve their motor function and daily living ability, and reduce the long-term disability rate.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy between herbal-moxa plaster and moxa-box moxibustion for diarrhea type irritable bowel syndrome (IBS-D) of spleen and kidney yang deficiency.@*METHODS@#Eighty patients with IBS-D of spleen and kidney yang deficiency were randomly divided into a herbal-moxa plaster group and a moxa-box moxibustion group, 40 cases in each group. The patients in the two groups were treated with conventional acupuncture at Baihui (GV 20), Yintang (GV 24+), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Yinlingquan (SP 9), and Taixi (KI 3), etc. In addition, the patients in the herbal-moxa plaster group were treated with herbal-moxa plaster (Wenyang Fuzheng ointment, composed of prepared monkshood, prepared evodia rutaecarpa, dried ginger, cinnamon, etc.) at Shenque (CV 8), Guanyuan (CV 4), Zhongwan (CV 12) and bilateral Tianshu (ST 25), Shenshu (BL 23) and Shangjuxu (ST 37); the patients in the moxa-box moxibustion group were treated with moxa-box moxibustion at the same acupoints as the herbal-moxa plaster group. The acupuncture-moxibustion treatment was provided once every other day for 4 weeks (14 treatments). Before and after treatment, the scores of clinical symptom of TCM, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life scale (IBS-QOL) were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Compared with those before treatment, each item scores and total scores of clinical symptom of TCM, and IBS-SSS scores in the two groups were reduced after treatment (P<0.05). The abdominal bloating score, stool frequency score and total score of clinical symptom of TCM as well as IBS-SSS score in the herbal-moxa plaster group were lower than those in the moxa-box moxibustion group (P<0.05). Compared with those before treatment, the IBS-QOL scores in the two groups were increased after treatment (P<0.05), and the IBS-QOL score in the herbal-moxa plaster group was higher than that in the moxa-box moxibustion group (P<0.05). The total effective rate was 92.5% (37/40) in the herbal-moxa plaster group, which was higher than 85.0% (34/40) in the moxa-box moxibustion group (P<0.05).@*CONCLUSION@#On the basis of conventional acupuncture treatment, herbal-moxa plaster could effectively improve the clinical symptoms and quality of life in IBS-D patients of spleen and kidney yang deficiency, and its efficacy is superior to that of moxa-box moxibustion.

ABSTRACT

OBJECTIVE@#To observe the effect of acupuncture combined with infantile tuina on intestinal flora and its efficacy in children with tic disorders (TD), and to explore its mechanism.@*METHODS@#A total of 15 children with TD were recruited as an observation group and 10 healthy children as a healthy control group. Regulating spleen and stomach acupuncture combined with infantile tuina were received in the observation group. First, acupuncture was applied to Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Hegu (LI 4), Zusanli (ST 36), etc., and then abdominal massage and other tuina techniques were applied, once a day, 6 times a week, 2 weeks as a course of treatment, a total of 2 courses of treatment were required. No intervention was given in the healthy control group. In the observation group, Yale global tic severity scale (YGTSS) score and TCM syndrome score were compared before treatment and after 1 and 2 courses of treatment. 16S rRNA sequencing technology was used to detect the intestinal flora in the healthy control group and before and after treatment in the observation group.@*RESULTS@#After 1 and 2 courses of treatment, the scores of YGTSS and TCM syndrome in the observation group were lower than those before treatment (P<0.01, P<0.05). Compared with the healthy control group, the number of operational taxonomic units (OTU) and indexes of Chao1, Sobs, Ace and Shannon were decreased in the observation group before treatment (P<0.05, P<0.01). Compared with before treatment, the number of OTU and indexes of Chao1, Sobs, Ace and Shannon were increased in the observation group after treatment (P<0.01, P<0.05). Compared with the healthy control group, the relative abundance of Firmicutes in the observation group before treatment was decreased (P<0.001), while the relative abundance of Bacteroidetes, Bacteroides and Erysipelatoclostridium was increased (P<0.001, P<0.05). Compared with before treatment, the relative abundance of Bacteroidetes in the observation group was decreased (P<0.001) after treatment, while the relative abundance of Actinobacteria, Bifidobacterium and Atopobium was increased (P<0.05, P<0.01).@*CONCLUSION@#Acupuncture combined with infantile tuina based on the principle of regulating spleen and stomach could effectively improve TD symptoms in children, which may be related to regulating the diversity of intestinal flora, increasing beneficial bacteria, maintaining intestinal microecological balance, and playing a role in improving neurological disorders.

ABSTRACT

The continuous pandemic coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)is a serious threat to human life and health because of high infectious pathogenicity, and it also has posed a new challenge to the current medical model. Many literatures have shown that these changes range from the more common ocular surface diseases such as inflammation of the cornea, conjunctiva, and sclera, to the relatively rare paracentral acute middle maculopathy and acute macular neuroretinopathy. For patients with ocular symptoms as the first or accompanying symptoms of SARS-CoV-2 infection, how to identify the correlation between ocular manifestations and SARS-CoV-2 infection is undoubtedly a serious challenge for ophthalmologists. In this review, the ocular pathology caused by both SARS-CoV-2 infection and vaccination was discussed, covering pathological changes in the ocular surface, uvea, retina and macula, and cranial nerves.

ABSTRACT

The epidemic of COVID-19 has brought great challenges to the global public health prevention and control system combined with clinical diagnosis and treatment system, and it makes the development of effective antiviral drugs an important task in current pharmaceutical research. Traditional Chinese medicine (TCM) has played an important role in the prevention and control of COVID-19. Due to its numerous chemical components and various structural types, TCM becomes a natural library for searching for lead compounds against SARS-CoV-2. In this study, a novel dual-target surface plasmon resonance (SPR) biosensor was developed for S protein receptor binding domain (SRBD) and angiotensin converting enzyme 2 (ACE2) which are two key proteins in the process of SARS-CoV-2 invading cells according to characteristics of synergistic effects of multiple components and comprehensive regulation of multiple targets of TCM. The SPR biosensor was applied to screen and identify active components from six TCMs, and daidzin from Puerariae Lobatae Radix was identified to bind with SRBD and ACE2. The affinity constant (KD) of daidzin and ACE2 was 5.18 μmol·L-1 through the SPR affinity assay. Competitive ELISA assay showed that daidzin could inhibit the binding of SRBD and ACE2, and the inhibition rate of daidzin (20 μmol·L-1) was 38.6%. Molecular docking experiments further confirmed that daidzin had the best binding near the binding region of SRBD-ACE2 complex. This study shows that the dual-target SPR screening system is accurate and efficient, and is particularly suitable for screening of complex drug systems and effective substances study of TCM. It provides a material basis for exploring the mechanism of TCM active constituents against SARS-CoV-2, and provides a source of lead compounds for the development of anti-SARS-CoV-2 drugs.

ABSTRACT

BACKGROUND/OBJECTIVES@#Soy isoflavone (SIF) and soy lecithin (SL) have beneficial effects on many chronic diseases, including neurodegenerative diseases. Regretfully, there is little evidence to show the combined effects of these soy extractives on the impairment of cognition and abnormal cerebral blood flow (CBF). This study examined the optimal combination dose of SIF + SL to provide evidence for improving CBF and protecting cerebrovascular endothelial cells.MATERIALS/METHODS: In vivo study, SIF50 + SL40, SIF50 + SL80 and SIF50 + SL160 groups were obtained. Morris water maze, laser speckle contrast imaging (LSCI), and hematoxylineosin staining were used to detect learning and memory impairment, CBF, and damage to the cerebrovascular tissue in rat. The 8-hydroxy-2′-deoxyguanosine (8-OHdG) and the oxidized glutathione (GSSG) were detected. The anti-oxidative damage index of superoxide dismutase (SOD) and glutathione (GSH) in the serum of an animal model was also tested. In vitro study, an immortalized mouse brain endothelial cell line (bEND.3 cells) was used to confirm the cerebrovascular endothelial cell protection of SIF + SL. In this study, 50 μM of Gen were used, while the 25, 50, or 100 μM of SL for different incubation times were selected first. The intracellular levels of 8-OHdG, SOD, GSH, and GSSG were also detected in the cells. @*RESULTS@#In vivo study, SIF + SL could increase the target crossing times significantly and shorten the total swimming distance of rats. The CBF in the rats of the SIF50 + SL40 group and SIF50 + SL160 group was enhanced. Pathological changes, such as attenuation of the endothelium in cerebral vessels were much less in the SIF50 + SL40 group and SIF50 + SL160 group. The 8-OHdG was reduced in the SIF50 + SL40 group. The GSSG showed a significant decrease in all SIF + SL pretreatment groups, but the GSH showed an opposite result. SOD was upregulated by SIF + SL pretreatment. Different combinations of Genistein (Gen)+SL, the secondary proof of health benefits found in vivo study, showed they have effective antioxidation and less side reaction on protecting cerebrovascular endothelial cell. SIF50 + SL40 in rats experiment and Gen50 + SL25 in cell test were the optimum joint doses on alleviating cognitive impairment and regulating CBF through protecting cerebrovascular tissue by its antioxidant activity. @*CONCLUSIONS@#SIF+SL could significantly prevent cognitive defect induced by β-Amyloid through regulating CBF. This kind of effect might be attributed to its antioxidant activity on protecting cerebral vessels.

ABSTRACT

Sleep occupies one-third of a person's lifetime and is a necessary condition for maintaining physiological function and health. With the increase in social and economic pressures, the growing use of electronic devices and the accelerated aging process of the population, insufficient sleep and its hazards have drawn widespread attention from researchers in China and abroad. Sleep deprivation refers to a decrease in sleep or a severe lack of sleep due to various reasons. Previous studies have found that sleep deprivation can cause extensive damage to the body, including an increased incidence and mortality rate of neuropathic diseases in the brain, cardiovascular diseases, imbalances in the gut microbiota, and other multi-organ diseases. The mechanisms underlying the occurrence of multi-system and multi-organ diseases due to sleep deprivation mainly involve oxidative stress, inflammatory responses, and impaired immune function in the body. According to traditional Chinese medicine(TCM), sleep deprivation falls into the category of sleepiness, and long-term sleepiness leads to Yin-Yang imbalance, resulting in the consumption of Qi and damage to the five Zang-organs. The appropriate treatment should focus on tonifying deficiency, reinforcing healthy Qi, and harmonizing Yin and Yang. TCM is characterized by a wide variety and abundant resources, and it has minimal side effects and a broad range of applications. Numerous studies have shown that TCM drugs and prescriptions not only improve sleep but also have beneficial effects on liver nourishment, intelligence enhancement, and kidney tonification, effectively preventing and treating the body injury caused by sleep deprivation. Given the increasing prevalence of sleep deprivation and its significant impact on body health, this article reviewed sleep deprivation-mediated body injury and its mechanism, summarized and categorized TCM compound prescriptions and single drugs for preventing and treating body injury, with the aim of laying the foundation for researchers to develop effective drugs for preventing and treating body injury caused by sleep deprivation and providing references for further exploration of the molecular mechanisms underlying the body injury caused by sleep deprivation.

ABSTRACT

The application of new-generation information technologies such as big data, the internet of things(IoT), and cloud computing in the traditional Chinese medicine(TCM)manufacturing industry is gradually deepening, driving the intelligent transformation and upgrading of the TCM industry. At the current stage, there are challenges in understanding the extraction process and its mechanisms in TCM. Online detection technology faces difficulties in making breakthroughs, and data throughout the entire production process is scattered, lacking valuable mining and utilization, which significantly hinders the intelligent upgrading of the TCM industry. Applying data-driven technologies in the process of TCM extraction can enhance the understanding of the extraction process, achieve precise control, and effectively improve the quality of TCM products. This article analyzed the technological bottlenecks in the production process of TCM extraction, summarized commonly used data-driven algorithms in the research and production control of extraction processes, and reviewed the progress in the application of data-driven technologies in the following five aspects: mechanism analysis of the extraction process, process development and optimization, online detection, process control, and production management. This article is expected to provide references for optimizing the extraction process and intelligent production of TCM.
