ABSTRACT
Objective: To observe the clinical efficacy of sinew-bone balancing manipulation in treating lumbar disc herniation (LDH) and offer clinical evidence to support the concept of paying equal attention to sinew and bone. Methods: Sixty LDH patients were randomized into an observation group and a control group, with 30 cases in each group. The observation group was treated with the sinew-bone balancing manipulation, and the control group received conventional Tuina (Chinese therapeutic massage) manipulation. The clinical efficacy and posterior muscle chain tone effect were compared between the two groups by observing the visual analog scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and posture-associated indicators. Results: The total effective rate was 86.7％ in the observation group, higher than 76.7％ in the control group, but the between-group difference in efficacy was statistically insignificant (P>0.05). After treatment, the VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry showed significant changes in both groups (P<0.05). The VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry in the observation group were significantly different from those in the control group after treatment (P<0.05), but the between-group difference in the general posture symmetry was statistically insignificant (P>0.05). Conclusion: Both the sinew-bone balancing and conventional Tuina manipulations can reduce pain in LDH patients, improve lumbar function, and adjust the angle-dependent muscle tone coefficient of the posterior muscle chain and lumbar posture symmetry; except for the general posture symmetry of the posterior muscle chain, the sinew-bone balancing manipulation wins out over the conventional Tuina manipulation.
ABSTRACT
Objective:To evaluate the association of HbA 1C level and variability with annual decline in glomerular filtration rate in elderly patients with type 2 diabetes. Methods:A total of 527 elderly type 2 diabetic patients with baseline estimated glomerular filtration rate(eGFR)≥60 mL·min -1·(1.73 m 2) -1 at the diabetes center of a tertiary hospital in Jiangsu province were included and followed up. The mean value and the variability of HbA 1C, including standard deviation(HbA 1C-SD), variation coefficient(HbA 1C-CV), and adjusted standard deviation(Adj-HbA 1C-SD) were calculated. According to the annual decreased rate of eGFR, the patients were divided into △eGFR>5% group and △eGFR≤5% group. Cox proportional risk regression model was used to evaluate the relationship between HbA 1C variability and the risk of decreased glomerular filtration rate. Results:With a mean follow-up time of 19 months, there were 176 patients whose △eGFR>5%. Compared with △eGFR≤5% group, the HbA 1C-mean and HbA 1C variability were significantly higher in △eGFR>5% group( P<0.05). Cox regression analysis showed that HbA 1C-mean, HbA 1C-SD, HbA 1C-CV, and Adj-HbA 1C-SD were significantly correlated with decreased glomerular filtration rate. After adjustment for age, gender, HbA 1C-mean, and other factors, only Adj-HbA 1C-SD was correlated with renal insufficiency [ HR=3.32(1.68-6.57)]. Conclusions:HbA 1C variability is independently associated with annual decline in glomerular filtration rate in elderly patients with type 2 diabetes. The Adj-HbA 1C-SD is the most sensitive indicator in predicting decreased glomerular filtration rate.
ABSTRACT
Objective:To investigate the effects of ginsenoside Rg1 (GS-Rg1) on the secretion of exosomes (MSC-Exo) and expression of angiogenesis related microRNAs (miRNAs) in mesenchymal stem cells.Methods:Human umbilical cord blood mesenchymal stem cells (hUCBMSCs) were divided into experimental group and control group. The experimental group was treated with GS-RG1 at a final concentration of 40 mg/L, while the control group was treated with phosphate buffered saline (PBS) at the same volume. Both groups were cultured for 24 h. The morphology of MSC-Exo was observed by transmission electron microscopy; the characteristic surface markers were identified by Western blot; the concentration of MSC-Exo was detected by dicootanobutyric acid protein quantification method, and the expression of 8 miRNAs related to angiogenesis in MSC-Exo was detected by reverse transcription polymerase chain reaction (RT-PCR).Results:After 24 h of incubation, MSC-Exo with a circular membrane vesicle structure was visible. MSC-Exo was positive for the expression of the characteristic surface markers CD9, CD63 and TSG101. After 24 h of intervention, the concentration of MSC-Exo protein were (1.080±0.019)μg/μl and (0.881±0.032)μg/μl in the experimental group and control group, respectively, with statistically significant difference ( P<0.01). The expression of miR-126-3p, miR-21, miR-146a-5p and miR-125b-5p in the GS-Rg1 group were significantly higher than that in the control group, while the expression of miR-16-5p was significantly lower than that in the control group (all P<0.05). Conclusions:GS-Rg1 promotes the secretion of MSC-Exo and enhances the expression of angiogenesis-related miRNAs within Exo to promote angiogenesis.
ABSTRACT
To study the parental origin and cell stage of nondisjunction in sex chromosome aneuploidies. Retrospectiving and analyzing the results of 385 cases of SCA confirmed by QF-PCR and karyotype analysis in the prenatal diagnosis center of Guangzhou Women and Children Medical Center from January 2015 to December 2020. The types of samples and prenatal diagnosis indications were analyzed. The parental origin and cell stage of nondisjunction in sex chromosome aneuploidies analyzed by comparing the short tandem repeat (STR) peak patterns of samples from fetuses and maternal peripheral blood. The results show that (1) There were 324 cases of nonmosaic SCA, 113 cases (113/324, 34.9%) were 45, XO, 118 cases (118/324, 36.4%) were 47, XXY, 48 cases (48/324, 14.8%) were 47, XXX and 45 cases (45/324, 13.9%) were 47, XYY. 68 (45/324, 60.2%) cases of 45, X were detected in villus samples. The other SCA cases were mainly detected in amniotic fluid samples. There were 61 mosaic SCA samples, 58(58/61, 95.1%) of mosaic SCA samples were mosaic 45, X. (2) The top two indications of 45, X cases are increased nuchal translucency(53/113, 46.9%) and fetal cystic hygroma (41/113, 36.3%), while the most common indication of other types of SCA was high risk of NIPT(170/272, 62.5%). (3) Among 45, X cases, there were 88 cases (88/113, 77.9%) inherit their single X chromosome from their mother and 25 cases (25/119, 22.1%) from their father. In 47, XXY samples, 47 cases (47/118, 39.8%) of chromosome nondisjunction occurred in meiosis stage Ⅰ of oocytes, 51 cases (51/118, 43.2%) occurred in meiosis stage Ⅰ of spermatocytes, and 20 cases (20/118, 16.9%) occurred in meiosis stage Ⅱ of oocytes. Among 47, XXX samples, 29 cases (29/48, 60.4%) of X chromosome nondisjunction occurred in meiosis stage Ⅰof oocytes, 15 cases (15/48, 31.3%) occurred in meiosis stage Ⅱ of oocytes, and 4 cases (4/48, 8.3%) occurred in meiosis stage Ⅱ of spermatocytes. In summary , the cases of 45, X were mainly diagnosed by villous samples for abnormal ultrasound findings. The other cases of SCA were mainly diagnosed by amniocentesis samples for abnormal NIPT results. Different types of SCA, the origin and occurrence period of sex chromosome nondisjunction were different.

Objective: To observe the effect of electroacupuncture (EA) of "concurrent treatment of the brain and heart" on angiogenesis and cortical vascular endothelial growth factor (VEGF) and brain-derived neurotrophic factor (BDNF) in rats with focal cerebral ischemia, and to explore the mechanism of EA in cerebral ischemia treatment. Methods: A total of 108 Sprague-Dawley rats, 27 rats were randomly selected as the sham-operation group, and the rest rats received the right middle cerebral artery occlusion operation for model preparation firstly, and then were divided into a model group, a traditional acupoint group, and a concurrent treatment of the brain and heart group, with 27 rats in each group. In the sham-operation group, only the carotid artery was isolated. EA at Shuigou (CV26), Quchi (LI11), Hegu (LI4), and Zusanli (ST36) in the traditional acupoint group, and EA at Fengfu (GV16), Baihui (GV20), Xinshu (BL15), and Neiguan (PC6) in the concurrent treatment of the brain and heart group were performed 4 h after the operation, once a day, for 14 consecutive days. Rats in the sham-operation group and the model group were identically fixed without any treatment. Before and after treatment, the modified neurological severity score (mNSS), regional cerebral blood flow (rCBF), and CD34 positive expression by immunohistochemistry were measured. The positive protein expression levels of VEGF and BDNF were detected by immunofluorescence, and the mRNA expression levels of VEGF and BDNF were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Results: Compared with the sham-operation group, the mNSS, rCBF, and ischemic side cortical micro-vessel density (MVD) decreased, and the protein and mRNA expression levels of VEGF and BDNF increased in the model group (P<0.01). Compared with the model group, the mNSS of the two EA groups decreased, and the mNSS of the concurrent treatment of the brain and heart group was lower than that of the traditional acupoint group on the 14th day (P<0.05). Compared with the model group, the rCBF in the two EA groups increased, and the rCBF reached the highest on the 14th day (P<0.05 or P<0.01), and the rCBF in the concurrent treatment of the brain and heart group was higher than that in the traditional acupoint group (P<0.05); the MVD of the two EA groups was higher than that of the model group, and the MVD of the concurrent treatment of the brain and heart group was higher than that of the traditional acupoint group on the 7th and 14th days (P<0.05 or P<0.01). Compared with the model group, the protein and mRNA expression levels of VEGF and BDNF in the two EA groups increased (P<0.01). The VEGF expression level was the highest on the 7th day in the concurrent treatment of the brain and heart group (P<0.05), and the BDNF expression level was higher on the 7th and 14th days than on the 3rd day (P<0.05). The mRNA expression levels of VEGF and BDNF in both EA groups reached the highest on the 7th day (P<0.05 or P<0.01). Conclusion: EA therapy can up-regulate the VEGF and BDNF expression levels and increase the rCBF in the cortex of rats with focal cerebral ischemia, which may be one mechanism of EA in the cerebral ischemia treatment. The therapeutic effect is accumulated with the effective time, and the concurrent treatment of the brain and heart group is superior to the traditional acupoint group in promoting angiogenesis.
ABSTRACT
The clinical data of 120 patients admitted to our hospital with renal stones treated by flexible ureteroscopy (FURS) and the imaging-related data measured by virtual reality technology were retrospectively analysed. The results of the univariate analysis showed that stone surface area (S), renal pelvis volume (P), length of calyces funnel (L), pelvic calyceal height (H) and essence of stone (E) were closely related to stone-free rate. The H. L.P.E.S. score was constructed to predict stone-free rate after FURS based on the above factors, and the area under the receiver aperating characteristic curve for the H. L.P.E.S. and S. O.L.V.E. scoring systems was 0.921 and 0.754 respectively.The H. L.P.E.S. scoring system has higher predictive value.
ABSTRACT
ObjectiveTo analyze the genetic characteristics of the hemagglutinin （H） gene of measles virus （MeV） in Shanghai， 2001‒2018. MethodsNasopharyngeal swab specimens were collected from suspected measles cases reported in Shanghai from 2001 to 2018， and the isolation of measles virus was conducted with Vero/hSLAM cell line. RT-PCR amplification and sequencing were conducted after RNA extraction to analyze the genetic characteristics of the complete H gene. ResultsIn total， 5 665 nasopharyngeal swab samples were collected by suspected measles case surveillance from 2001 to 2018， and 1 394 measles virus strains were isolated. The homology of nucleotide acid and amino acid among 349 representative measles virus isolates was 87.4%‒100.0% and 85.1%‒100.0%， respectively. The homology of nucleotide acid and amino acid between representative measles virus isolates and China vaccine strain （S191） was 85.7%‒100.0% and 84.1%‒100.0%， respectively. All the sub-genotype H1a MeV isolates had an amino acid substitution （Ser240Asn）， which removed a predicted N-linked glycosylation site. ConclusionMost of the MeV isolates are sub-genotype H1a analyzed based on H gene， which are identical to those of the N gene. The predicted amino acid sequences of the H protein are relatively conserved at most of the functionally significant amino acid positions.
ABSTRACT
AIM: To observe the changes of the morphology and structure of macula, blood flow density of macula and optic disc, as well as retinal nerve fiber layer thickness by optical coherence tomography(OCT)and optical coherence tomography angiography(OCTA)in patients with rhegmatogenous retinal detachment(RRD)under went sclera buckling(SB). METHODS: As a cross-sectional case-controlled study, 25 patients(25 eyes)were diagnosed with RRD in the department of ophthalmology, Ganzhou People's Hospital from July 2014 to March 2021. The differences in the vascular density(VD)of superficial vessel cluster(SVC), the VD of deep vessel cluster(DVC)of macula, the SVC-VD of optic disc, retinal nerve fiber layer(RNFL), central macular thickness(CMT), subfoveal choroidal thickness(SFCT)and outer structure of macula between the affected eyes and healthy eyes at the last post-operative follow-up were compared, and the correlation indicators affecting best corrected visual acuity(BCVA, LogMAR)of the affected eyes at the last follow-up were analyzed. RESULTS: There were no statistically significant in SVC-VD and DVC-VD of macula, SVC-VD of optic disc, RNFL, CMT, SFCT between the affected eyes and healthy eyes at the last post-operative follow-up(all P>0.05); At the last follow-up visit, the comparison of macular outer structure on OCT between the affected eyes and the healthy eyes showed that the light band integrity of the external limiting membrane(ELM), myoid zone(MZ), ellipsoid zone(EZ)and outer segment of photoreceptor(OS)had no statistically significant difference(all P>0.05), while the light band integrity of interdigitation zone(IZ)had significant difference(P=0.014); The difference of BCVA(LogMAR)between the affected eyes and the healthy eyes at the last follow-up was statistically significant(P=0.002). There was significant correlation between BCVA(LogMAR)of affected eyes at the last post-operative follow-up and the presence or absence of macular involvement, the correlated with SVC-VD of optic disc, the integrity of the light bands of ELM, MZ, EZ, OS and IZ on the outer structure of macula, it was positively correlated with the presence or absence of macular involvement(rs=0.401, P=0.047)and it was negatively correlated with SVC-VD of optic disc, the integrity of the light bands of ELM, MZ, EZ, OS and IZ on the outer structure of macula(all P<0.05).CONCLUSION: The OCT and OCTA can be used to observe fundus changes after SB surgery for RRD to obtain long-term follow-up information related to vision prognosis, and visual prognosis depends on the recovery of retinal outer structure, and the integrity of IZ structure is more important for visual recovery; The SVC-VD of optic disc is correlated with visual prognosis, and whether it was correlated with intraocular pressure require further observation and verification with postoperative continuous data.
ABSTRACT
Phosphodiesterase-4 (PDE4) functions as a catalyzing enzyme targeting hydrolyzation of intracellular cyclic adenosine monophosphate (cAMP) and inhibition of PDE4 has been proven to be a competitive strategy for dermatological and pulmonary inflammation. However, the pathological role of PDE4 and the therapeutic feasibility of PDE4 inhibitors in chronic ulcerative colitis (UC) are less clearly understood. This study introduced apremilast, a breakthrough in discovery of PDE4 inhibitors, to explore the therapeutic capacity in dextran sulfate sodium (DSS)-induced experimental murine chronic UC. In the inflamed tissues, overexpression of PDE4 isoforms and defective cAMP-mediating pathway were firstly identified in chronic UC patients. Therapeutically, inhibition of PDE4 by apremilast modulated cAMP-predominant protein kinase A (PKA)-cAMP-response element binding protein (CREB) signaling and ameliorated the clinical symptoms of chronic UC, as evidenced by improvements on mucosal ulcerations, tissue fibrosis, and inflammatory infiltrations. Consequently, apremilast maintained a normal intestinal physical and chemical barrier function and rebuilt the mucosal homeostasis by interfering with the cross-talk between human epithelial cells and immune cells. Furthermore, we found that apremilast could remap the landscape of gut microbiota and exert regulatory effects on antimicrobial responses and the function of mucus in the gut microenvironment. Taken together, the present study revealed that intervene of PDE4 provided an infusive therapeutic strategy for patients with chronic and relapsing UC.
ABSTRACT
OBJECTIVE@#To observe the clinical characteristics, treatment and prognosis of intestinal acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children and futher evaluate the occurring risk factors.@*METHODS@#The clinical data of 136 patients undergoing allo-HSCT in Wuhan Children's Hospital Affiliated to Tongji Medical College from August 2016 to August 2020 were retrospectively analyzed, clinical characteristics of children with intestinal aGVHD were observed. The risk factors of intestinal aGVHD were assessed by logistic regression while cumulative survival were analyzed by Kaplan-Meier method.@*RESULTS@#Among 136 patients intestinal aGVHD occurred in 24 (17.6%) cases, with 4 cases of grade II, 20 cases of grade III-IV, and the median occurrence time was 28(10-63) days. The clinical manifestations were diarrhea with intermittent abdominal pain, 17 cases with nausea and vomiting, 11 cases with fresh bloody stool, and 8 cases with skin rash before intestinal aGVHD. The average time for treatment was 33(11-100) days. 18 cases received electronic colonoscopy and histopathology examination. 20 out of 24 cases achieved remission after treatment, and the total effective rate was 83.3%. Finally, 9 out of 24 cases died during the follow-up time. Survival analysis showed that the cumulative survival rate of patients with intestinal aGVHD (15/24, 62.5%) were significantly lower than those without intestinal aGVHD (101/112, 90.2%) (Log-rank test, P=0.001). Univariate analysis showed that recipient age, sex, primary disease, donor age, donor sex, donor-recipient blood type, conditioning regimen, prophylaxis of GVHD, dosage of ATG, engraft time of blood platelet and neutrophils, and number of MNC/CD34+ were not risk factors for intestinal aGVHD (P>0.05). Only the type of HSCT (χ2=16.020, P=0.001) and matched degree of HLA (χ2=15.502, P=0.001) had statistical significance with intestinal aGVHD (P<0.05). Multivariate analysis showed that only HLA-mismatched unrelated donor was the risk factor for intestinal aGVHD for children (P=0.014，OR=16，95%CI 1.735-147.543).@*CONCLUSION@#Intestinal aGVHD is a risk factor for cumulative survial of patients who received allo-HSCT in children and HLA-mismatched unrelated donor is its independent risk factor.

Objective:To analyze the clinical data of children with hydrocephalus suffering from subdural effusion/hematoma after shunt(SEHS) with adjustable valves, and to provide reference for postoperative follow-up.Methods:A total of 102 children with hydrocephalus treated with adjustable valves in the Department of Neurosurgery, Wuhan Children′s Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from August 2017 to September 2021 were enrolled and studied retrospectively.There were 16 cases with SEHS, 11 of whom were male and 5 were female.The age ranged from 3 months to 13 years (median: 2.5 years). The age, clinical manifestations, the time of SEHS occurrence, treatment methods(pressure regulation only or combined with drilling and drainage), and prognosis of the patients were analyzed.The pressure adjustment treatment was to increase the by 10-20 mmH 2O (1 mmH 2O=0.009 8 kPa) each time and the patients were followed up 2-4 weeks after the adjustment.If SEHS didn′t improve according to the follow-up results, pressure regulation combined with drilling and drainage was recommended. Results:Of the 16 patients with SEHS, 3 cases were over 3 years old, and the other 13 cases were 3 years old or below.Eleven cases were treated by pressure regulation only, and 5 cases who were all aged ≤3 years received pressure regulation combined with drilling and drainage.Symptoms occurred in 2 patients, including vomiting in 1 case, and head and limb shaking in the other case.Fourteen cases were asymptomatic.The time from shunt operation to the occurrence of SEHS was ≤1 month in 5 cases, who were all cured by pressure regulation only.SEHS occurred in 5 cases >1-3 months after shunt surgery, and 2 cases of them were treated by pressure regulation combined with dri-lling and drainage.Three cases had SEHS>3-6 months after shunt surgery, and 1 case of them was treated by pressure regulation combined with drilling and drainage.SEHS occurred in 3 cases more than 6 months after shunt surgery, and 1 case of them was treated by pressure regulation combined with drilling and drainage.For the patients who received pressure regulation combined with drilling and drainage, the time from shunt operation to the occurrence of SEHS was 1 month and 21 days, 2 months and 7 days, 4.5 months, 7.5 months, and 25.0 months, respectively.The time from the occurrence of SEHS to the last reexamination with no SEHS detected was ≤1 month in 7 cases (all were cured by pressure regulation only); >1-3 months in 5 cases (3 cases were treated by pressure regulation combined with drilling and drainage); more than 3 months in 4 cases (2 cases were treated by pressure regulation combined with drilling and drainage). For the patients who received pressure regulation combined with drilling and drainage, the time from the occurrence of SEHS to the last reexamination with no SEHS detected was 1 month and 14 days, 2.0 months, 3.0 months, 7.0 months and 8.0 months, respectively.Except for 2 cases who experienced pressure regulating valve failure, all other cases were cured.Six cases were unilateral SEHS, and the SEHS volume was about 11 to 75 mL (median: 39.0 mL). Ten cases were bilateral SEHS, and the SEHS volume was about 23-380 mL (median: 158.2 mL). The 6 cases were all cured by pressure regulation, and 5 cases of them had SEHS at the shunt tube insertion side.Conclusions:SEHS in children with hydrocephalus is generally asymptomatic and rarely causes clinical symptoms.SEHS mostly occurs within 6 months after operation, especially within 3 months.SEHS found in 1 month after surgery can be cured by increasing the shunt valve pressure only.Therefore, SEHS can be cured by pressure regulation only by shortening follow-up and identifying SEHS early after shunt operation.This will also reduce the probability that patients require the drilling and drainage operation.
ABSTRACT
Tongue diagnosis is one of the diagnostic methods of Traditional Chinese Medicine (TCM), but its development has always been restricted by the lack of objective quantitative indicators. With the rapid development of computer technology and the advent of the algorithm era, the modernization of TCM tongue diagnosis has gradually become a hot research spot. This paper annalyses the literature and related patents of the modernization of tongue diagnosis and summarizes the R&D progress and application of tongue diagnosis as well as related instruments. It is found that domestic and foreign scholars focus on tongue diagnosis related research and attach importance to the formulation of relevant international standards. Tongue collection and analysis technology continues to develop; tongue diagnostic instruments are also gradually enriched. At present, their applications are extended to family self-use, but they are still mainly used in teaching, scientific research and other fields, involving the clinical efficacy evaluation of TCM, clinical case classification and health management, and there is still much room for development. In the future, we should strengthen the communication between multi-regional research centers, promote the communication among talents in different fields, constantly make up for the deficiencies and promote the development of tongue diagnosis research.
ABSTRACT
Objective:To investigate the value of 95% spectral edge frequency (SEF) in identifying the depth of anesthesia in patients with schizophrenia subjected to modified electroconvulsive therapy center.Methods:A total of 195 patients with schizophrenia who received treatment in The Affiliated Kangning Hospital of Wenzhou Medical University in April to December 2020 were included in this study. They were randomly divided into three groups with 65 patients each. Three groups of patients received different doses of anesthesia before undergoing MECT as follows: group A: propofol 1.5 mg/kg, atropine 0.5 mg/kg, succinylcholine chloride 1.0 mg/kg; group B: propofol 2.0 mg/kg, atropine 0.5 mg/kg, succinylcholine chloride 1.0 mg/kg; group C: propofol 2.5 mg/kg, atropine 0.5 mg/kg, succinylcholine chloride 1.0 mg/kg. 95% SEF and bispectral index (BIS) were measured when patients were awake before treatment (T 1), when eyelash reflex disappeared (T 2), at the beginning of electrical stimulation (T 3), at 3 minutes after electrical stimulation (T 4), and when patients were completely awake (T 5) and compared between groups. The incidence of adverse reaction was recorded at 1 day after treatment. Results:At T 1-T 5, 95% SEF in the group A was (28.50 ± 0.87) Hz, (21.49 ± 0.91) Hz, (21.99 ± 0.92) Hz, (28.42 ± 1.29) Hz, (28.40 ± 1.15) Hz respectively, and it was (28.34 ± 0.91) Hz, (18.93 ± 0.86) Hz, (19.05 ± 0.83) Hz, (27.54 ± 0.73) Hz, (28.42 ± 1.21) Hz respectively in group B and (28.26 ± 0.90) Hz, (16.41 ± 0.75) Hz, (16.36 ± 0.75) Hz, (26.58 ± 0.64) Hz, (28.48 ± 1.19) Hz respectively in group C. 95% SEF measured at T 2 ( t = 24.49, 48.60, both P < 0.05), T 3 ( t = 28.47, 54.51, both P < 0.05), and T 4 ( t = 7.61, 15.91, both P < 0.05) in groups B and C were significantly lower than those in group A. 95% SEF measured at T 2 ( t = 24.11, P < 0.05), T 3 ( t = 26.04, P < 0.05) and T 4 ( t = 8.30, P < 0.05) in group C were significantly lower than those in group B. At T 1-T 5, BIS in group A was (94.16 ± 2.07), (55.34 ± 1.93), (56.61 ± 1.84), (76.29 ± 1.94) and (93.84 ± 2.39) respectively, and it was (94.51 ± 2.25), (52.39 ± 1.58), (52.45 ± 1.94), (73.58 ± 2.19), (93.28 ± 2.52) respectively in group B and (93.97 ± 2.16), (50.57 ± 1.96), (51.60 ± 2.03), (69.51 ± 2.12), (93.57 ± 2.66) respectively in group C.

BIS measured at T 2 ( t = 24.11, P < 0.05), T 3 ( t = 25.93, P < 0.05), and T 4 ( t = 8.30, P < 0.05) in group C were significantly lower than those in group B. Correlation analysis showed that 95% SEF measured at T 2 ( r = 0.65, P < 0.05), T 3 ( r = 0.68, P < 0.05) and T 4 ( r = 0.49, P < 0.05) were positively correlated with BIS measured at corresponding time points. There were no significant differences in duration of electrical stimulation [(61.25 ± 4.32) seconds, (45.19 ± 3.68) seconds, and (27.54 ± 2.54) seconds, F = 1 434.14, P < 0.05], post-onset inhibition index [(87.68 ± 5.82)%, (81.59 ± 5.35)%, (75.27 ± 4.87)%, F = 87.09, P < 0.05], and average seizure energy index [(5 668.38 ± 1 264.01) μV2, (4 555.61 ± 1 058.96) μV2, (3 642.25 ± 792.68) μV2, F = 59.97, P < 0.05] among the three groups. Duration of electrical stimulation ( t = 36.07, 75.71, both P < 0.05), post-onset inhibition index ( t = 9.15, 18.66, both P < 0.05), and average seizure energy index ( t = 8.49, 15.46, both P < 0.05) in groups B and C were significantly lower than those in group A. Duration of electrical stimulation, post-onset inhibition index and average seizure energy index in group C were significantly lower than those in group B ( t = 39.64, 9.50, 6.97, all P < 0.05). BIS was positively correlated with duration of electrical stimulation ( r = 0.68, P < 0.05), post-onset inhibition index ( r = 0.55, P < 0.05) and average seizure energy index ( r = 0.42, P < 0.05). There were no significant differences in the incidences of headache, myalgia, nausea and vomiting among the three groups ( P > 0.05). Conclusion:95% SEF was positively correlated with BIS in patients with schizophrenia. BIS measured at T 2 was positively correlated with effect of modified electroconvulsive therapy center.

Hsp90 is often overexpressed with activated form in cancer cells, and many key cellular proteins are dependent upon the Hsp90 machinery (these proteins are called “client protein”). Nowadays, more client proteins and more inhibitors of Hsp90 are being discovered. Chaetocin has been identified as an inhibitor of histone methyl transferase SUV39H1. Herein, we find that Chaetocin is an inhibitor of Hsp90 which binds to the C-terminal of Hsp90α. Chaetocin inhibited a variety of Hsp90 client proteins including AMl1-ETO and BCL-ABL, the mutant fusion-protein in the K562 and HL-60 cells. SUV39H1 mediates epigenetic events in the pathophysiology of hematopoietic disorders. We found that inhibition of Hsp90 by Chaetocin and 17-AAG had ability to induce degradation of SUV39H1 through proteasome pathway. In addition, SUV39H1 interacted with Hsp90 through co-chaperone HOP.These results suggest that SUV39H1 belongs to a client protein of Hsp90. Moreover, Chaetocin was able to induce cell differentiation in the two cells in the concentration range of Hsp90 inhibition. Altogether, our results demonstrate that SUV39H1 is a new client protein of Hsp90 degradated by Chaetocin as a novel C-terminal inhibitor of Hsp90. The study establishes a new relationship of Chaetocin and SUV39H1, and paves an avenue for exploring a new strategy to target SUV39H1 by inhibition of Hsp90 in leukemia.
ABSTRACT
We conducted a randomized, open-label, parallel-controlled, multicenter trial on the use of Shuanghuanglian (SHL), a traditional Chinese patent medicine, in treating cases of COVID-19. A total of 176 patients received SHL by three doses (56 in low dose, 61 in middle dose, and 59 in high dose) in addition to standard care. The control group was composed of 59 patients who received standard therapy alone. Treatment with SHL was not associated with a difference from standard care in the time to disease recovery. Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group (93.4% vs. 73.9%, P = 0.006). Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia, which was evaluated by density reduction of inflammatory focus from baseline, at day 7 (mean difference (95% CI), -46.39 (-86.83 to -5.94) HU; P = 0.025) and day 14 (mean difference (95% CI), -74.21 (-133.35 to -15.08) HU; P = 0.014). No serious adverse events occurred in the SHL groups. This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.

OBJECTIVES@#This study was performed to investigate the effects of hyperbaric oxygen and other approaches for treating the osteoradionecrosis of the jaws (ORNJ) systematically.@*METHODS@#According to the preset inclusion and exclusion criteria, randomized controlled trials and cohort studies on hyperbaric oxygen in the treatment of ORNJ were screened, and foreign language databases such as PubMed, EMBASE, and Cochrane library were searched via a computer; Chinese databases such as CNKI, VIP, Wanfang data, and CBM were searched from the established database to September 2020. Relevant books were searched manually to collect all literatures on the efficacy of hyperbaric oxygen and its related therapies in ORNJ treatment. Two researchers were independent and mutually blind, the papers were selected, data were collected, and the bias risk was evaluated. If any difference was detected, it would be decided by discussion or arbitrated by a third party. The data related to the efficacy of hyperbaric oxygen and its related therapy in the treatment of the ORNJ were extracted, and the Revman5.4 software was used for Meta-analysis. In case of large heterogeneity, sensitivity analysis was performed. A funnel chart was used to evaluate possible publication bias qualitatively.@*RESULTS@#Four randomized controlled trials and seven cohort studies were included in Meta-analyses. In ORNJ treatment, no significant differences between the group subjected to hyperbaric oxygen and both surgery and antibiotics and the group that underwent both surgery and antibiotics (RR=1.16, 95%CI: 0.86~1.58, @*CONCLUSIONS@#Hyperbaric oxygen therapy cannot replace surgery and antibiotic therapy. Hyperbaric oxygen therapy is not superior to antibiotics and antifibrotic drugs, but the benefits of antifibrotic drugs should be further explored.

BACKGROUND@#With the wide application of endoscopic submucosal dissection (ESD) for early gastric neoplasms, metachronous gastric neoplasms (MGN) have gradually become a concern. This study aimed to analyze the characteristics of MGN and evaluate the treatment and follow-up outcomes of MGN patients.@*METHODS@#A total of 814 patients were retrospectively enrolled. All these patients were treated by ESD for early gastric cancer or gastric dysplasia between November 2006 and September 2019 at The First Medical Center of Chinese People's Liberation Army General Hospital. The risk factors for MGN were analyzed using Cox hazard proportional model. Moreover, the cumulative incidence, the correlation of initial lesions and MGN lesions, and the treatment and follow-up outcomes of MGN patients were analyzed.@*RESULTS@#A total of 4.5% (37/814) of patients had MGN after curative ESD. The 3-, 5-, and 7-year cumulative incidences of MGN were 3.5%, 5.1%, and 6.9%, respectively, and ultimately reaching a plateau of 11.3% at 99 months after ESD. There was no significant correlation between initial lesions and MGN lesions in terms of gross type (P = 0.178), location (long axis: P = 0.470; short axis: P = 0.125), and histological type (P = 0.832). Cox multivariable analysis found that initial multiplicity was the only independent risk factor of MGN (hazard ratio: 4.3, 95% confidence interval: 2.0-9.4, P < 0.001). Seventy-three percent of patients with MGN were treated by endoscopic resection. During follow-up, two patients with MGN died of gastric cancer with lymph node metastasis. The disease-specific survival rate was significantly lower in patients with MGN than that in patients without MGN (94.6% vs. 99.6%, P = 0.006).@*CONCLUSIONS@#The MGN rate gradually increased with follow-up time within 99 months after curative gastric ESD. Thus, regular and long-term surveillance endoscopy may be helpful, especially for patients with initial multiple neoplasms.

Objective: To observe the incidence and treatment of radiation rectal injury complicated with anxiety, depression and somatic symptom disorder. Methods: A cross-sectional survey research method was carried out. Patients with radiation rectal injury managed by members of the editorial board of Chinese Journal of Gastrointestinal Surgery were the subjects of investigation. The inclusion criteria of the survey subjects: (1) patients suffered from pelvic tumors and received pelvic radiotherapy; (2) colonoscopy showed inflammatory reaction or ulcer in the rectum. Exclusion criteria: (1) patient had a history of psycho-somatic disease before radiotherapy; (2) patient was unable to use a smart phone, unable to read and understand the questions in the questionnaire displayed on the phone; (3) patient refused to sign an informed consent form. According to the SOMA self-rating scale, PHQ-15 self-rating scale, GAD-7 and PHQ-9 self-rating scale, the electronic questionnaire of "Psychological Survey of Radiation Proctitis" was designed. The questionnaire was sent to patients with radiation rectal injury managed by the committee through the WeChat group. Observational indicators: (1) radiation rectal injury symptom assessment: using SOMA self-rating scale, radiation rectal injury symptom classification: mild group (≤3 points), moderate group (4-6 points) and severe group (> 6 points); (2) incidence of anxiety, depression and physical disorder: using GAD-7, PHQ-9 and PHQ-15 self-rating scales respectively for assessment; (3) correlation of radiation rectal injury symptom grading with anxiety, depression, and somatic symptom disorder. Results: Seventy-one qualified questionnaires were collected, of which 41 (56.9%) were from Guangzhou. Among the 71 patients, 6 were males and 65 were females; the mean age was (55.7±9.3) years old and 48 patients (67.6%) were less than 60 years old; the median confirmed duration of radiation rectal injury was 2.0 (1.0, 5.0) years. (1) Evaluation of symptoms of radiation rectal injury: 18 cases of mild (25.4%), 27 cases of moderate (38.0%), and 26 cases of severe (36.6%). (2) Incidence of anxiety, depression and somatic disorder: 12 patients (16.9%) without comorbidities; 59 patients (83.1%) with anxiety, depression, or somatic disorder, of whom 2 patients only had anxiety, 1 patient only had depression, 9 only had somatic disorder, 2 had anxiety plus depression, 4 had anxiety plus somatic disorder, 2 had depression plus somatic disorder, and 40 had all three symptoms. (3) correlation of radiation rectal injury grading with anxiety, depression, and somatic symptom disorder: as compared to patients in mild group and moderate group, those in severe group had higher severity of anxiety and somatic symptom disorder (Z=-2.143, P=0.032; Z=-2.045, P=0.041), while there was no statistically significant difference of depression between mild group and moderate group (Z=-1.176, P=0.240). Pearson correlation analysis revealed that radiation rectal injury symptom score was positively correlated with anxiety (r=0.300, P=0.013), depression (r=0.287, P=0.015) and somatic symptom disorder (r=0.344, P=0.003). Conclusions: The incidence of anxiety, depression, and somatic symptom disorder in patients with radiation rectal injury is extremely high. It is necessary to strengthen the diagnosis and treatment of somatic symptom disorder, so as to alleviate the symptoms of patients with pelvic perineum pain and improve the quality of life.

Objective:To study the protective effect of polysaccharides from Plantaginis Semen （PSP） against renal injury in rats with membranous nephropathy （MN） and its influence on the gut microbiota to provide a theoretical basis for the further investigation of PSP in the treatment of MN. Method:The MN model was induced by tail vein injection of cationic bovine serum albumin （C-BSA， 3.5 g·L<sup>-1</sup>） in rats with a modeling period of seven weeks. At the 4th week of modeling， the model rats were divided into a model group， a positive drug group （benazepril hydrochloride， 10 mg·kg<sup>-1</sup>·d<sup>-1</sup>）， a PSP high-dose group （PSP-H， 800 mg·kg<sup>-1</sup>·d<sup>-1</sup>）， a PSP medium-dose group （PSP-M， 400 mg·kg<sup>-1</sup>·d<sup>-1</sup>）， and a PSP low-dose group （PSP-L， 200 mg·kg<sup>-1</sup>·d<sup>-1</sup>） according to the random number table， with 10 in each group. Ten healthy rats were assigned to the normal control group. The rats in the normal control group and the control group received an equal amount of physiological saline by gavage， and those in the groups with drug intervention were administered correspondingly，once a day，for consecutive four weeks. The pathological changes of rat kidney and colon tissues were observed by optical microscopy. The enzyme-linked immunosorbent assay （ELISA） was used to detect the content of tumor necrosis factor-<italic>α </italic>（TNF-<italic>α</italic>） and interleukin-1<italic>β </italic>（IL-1<italic>β</italic>） in the serum and colon tissues. The immunohistochemistry （IHC） was used to detect the protein expression of TNF-<italic>α </italic>and IL-1<italic>β </italic>in renal tissues. The 16S rRNA sequencing method was used to investigate the effect of PSP on the gut microbiota in MN rats. Result:Compared with the normal control group， the model group showed enlarged glomeruli， thickened basement membrane， atrophied colonic gland， increased TNF-<italic>α</italic> and IL-1<italic>β</italic> in the serum and colon tissues （<italic>P</italic><0.05）， and elevated protein expression of TNF-<italic>α</italic> and IL-1<italic>β </italic>（<italic>P</italic><0.01）. Compared with the model group， the positive drug group and the PSP-H group displayed shrunk glomerular capsules， relieved basement membrane thickening， and neatly arranged colonic mucosa in colon tissues， while the PSP-M and PSP-L groups were inferior in improving renal tissues and colon tissues. Additionally， the PSP-H and PSP-M groups showed declining TNF-<italic>α</italic> and IL-1<italic>β</italic> in the serum and colon tissues （<italic>P</italic><0.05） and dwindled protein expression of TNF-<italic>α</italic> and IL-1<italic>β </italic>in the renal tissues （<italic>P</italic><0.01）. No significant difference was observed in the PSP-L group. Compared with the normal control group， the model group showed increased abundance of Firmicutes and decreased abundance of Bacteroidetes. After PSP intervention， the abundance of Firmicutes was decreased， while that of Bacteroidetes was increased， and such changes were predominant in the PSP-H group. Conclusion:PSP can effectively alleviate renal injury， reduce the expression of inflammatory factors， regulate the structure of gut microbiota， and improve the damaged intestinal barrier of MN rats.
ABSTRACT
OBJECTIVE@#To study the characteristics of gut microbiota and its association with the activity of β-glucuronidase (β-GD) in neonates with hyperbilirubinemia.@*METHODS@#A total of 50 neonates with hyperbilirubinemia who were admitted in January to December, 2018, were enrolled as the hyperbilirubinemia group, and 30 neonates without hyperbilirubinemia were enrolled as the control group. The 16S rRNA high-throughput sequencing method was used to compare gut microbiota between the two groups. The phenolphthalein-glucuronic acid substrate method was used to measure the activity of β-GD in the intestinal tract of neonates with hyperbilirubinemia before and after treatment.@*RESULTS@#The comparison of the distribution of gut microbiota at the genus level showed a significant difference in the abundance of 52 bacteria between the hyperbilirubinemia and control groups before treatment (@*CONCLUSIONS@#There are differences in gut microbiota between the neonates with hyperbilirubinemia and those without hyperbilirubinemia.
