RÉSUMÉ

BACKGROUND:Pressing massage applied to myofascial trigger points(MTrPs)has shown clear effect in relieving pain.However,further research is needed to investigate the effects of different levels of pressure applied during the massage. OBJECTIVE:To investigate the different strength of pressing on MTrPs in rats with chronic pain. METHODS:Sixty SPF-rated male Sprague-Dawley rats were randomly divided into a blank group of 10 rats not involved in MTrPs modeling and 50 rats involved in modeling.The MTrPs model was established in the left medial thigh muscle of rats by blunt strikes combined with centrifugal exercise and 40 rats that met the evaluation criteria after modeling were randomly divided into model group,light press group,medium press group and heavy press group,with 10 rats in each group.The rats in the blank group and the model group were not intervened,while the rats in the light press group,the medium press group and the heavy press group were intervened with a homemade press stimulator with light force(0.3 kg),medium force(0.5 kg)and heavy force(0.7 kg)to MTrPs.The intervention time was 7.5 minutes per session,with one session every other day,totaling seven sessions.Electromyogram,soft tissue tension and mechanical pain threshold were detected by electrophysiological instruments,soft tissue tension tester,and pressure painmeter,respectively.After the intervention,in the blank group,muscle tissue was taken from the inside of the left thigh,while in the other groups,MTrPs tissue was taken.The pathological morphology was observed by hematoxylin-eosin staining,while enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of cyclooxygenase-2,prostaglandin E2 and bradykinin. RESULTS AND CONCLUSION:Compared with the blank group,the model group had lower mechanical pain thresholds,higher soft tissue tone,higher amplitude frequency of spontaneous electrical activity,significant pathomorphological changes,and increased levels of cyclooxygenase-2,prostaglandin E2 and bradykinin(P<0.05).Compared with the model group,the medium press group and the heavy press group showed increased mechanical pain thresholds,decreased soft tissue tension,decreased spontaneous potential frequency amplitude,and decreased levels of cyclooxygenase-2,prostaglandin E2 and bradykinin(P<0.05),and significant recovery on pathomorphological changes.No significant changes in the above indicators were observed in the light press group(P>0.05).Compared with the medium press group,the heavy press group showed better improvement in the above indicators(P<0.05).To conclude,moderate to heavy pressing is often required to alleviate MTrPs pain.

RÉSUMÉ

AIM: To evaluate the refractive outcomes after intrascleral fixation of posterior intraocular lens(IOL).METHODS: Retrospective clinical study. A total of 55 patients(55 eyes)who had undergone intrascleral fixation of posterior IOL in Peking University International Hospital from March 2017 to December 2021 were enrolled. Patients were assigned to conventional group(35 eyes)and modified group(20 eyes)according to different surgical procedures. IOL Master combined with SRK/T formula were applied to calculate the diopter of IOL and the residual refractive power, as well as acquiring preoperative values of corneal astigmatism. Optometry, IOL Master and Pentacam were performed 1 and 3mo postoperatively to obtain the postoperative corneal astigmatism, total ocular astigmatism and spherical equivalent which was calculated as the actual diopter. The Image-pro plus analyzer was used to measure the values of IOL tilt and decentration.RESULTS: The 55 eyes that underwent intrascleral fixation of posterior IOL presented hyperopic shift in refraction after operation and the refractive error was 0.75±0.63D at 3mo postoperatively. There was significant difference between the actual diopter and the residual diopter at 3mo after operation(t=2.553, P=0.011). Both conventional group and modified group showed hyperopic shift postoperatively. The refractive error at 1 and 3mo after operation were 0.80±0.43 and 0.84±0.46D in the conventional group and 0.43±0.39 and 0.47±0.26D in the modified group respectively, with significant differences between two groups(1mo: t=3.500, P=0.001; 3mo: t=3.311, P=0.002). There was no significant difference in corneal astigmatism between two groups both at 1 and 3mo postoperatively(all P<0.05). Total ocular astigmatism in the modified group was significantly lower than that in the conventional group(1mo: t=3.884, P<0.001; 3mo: t=3.314, P=0.002). In addition, IOL tilt and decentration in the modified group were significantly less than that in the conventional group at 1 and 3mo postoperatively(all P<0.05). No significant difference was found in IOL tilt and decentration for intra-group comparison at 1 and 3mo postoperatively(P<0.05). Complications of 55 eyes included 2 eyes of transient intraocular pressure elevation, 2 eyes of transient hypotony which recovered after topical medication and 1 eye of vitreous hemorrhage which resolved spontaneously.CONCLUSION: Intrascleral fixation of posterior IOL is proved to be a safe and effective surgical technique, with hyperopic shift easily present after operation. Increasing the refractive power of IOL and targeting mild myopia during IOL power calculation can prevent postoperative hyperopia, but long-term outcomes still need further observation.

ObjectiveTo analyze the causes of death and years of life lost among patients with severe mental disorders in Jining city, in order to provide references for improving the management level of the patients. MethodsA total of 3 638 patients with severe mental disorders who were recorded in the National Information System for Severe Mental Disorders in Jining and died between January 1, 2014 and December 31, 2020 were included in the study. The general information and the status of mortality were extracted via checking management files. Thereafter, the causes of death of patients with different characteristics were discussed, and the years of life lost due to severe mental disorders was analyzed through calculating potential years of life lost (PYLL), average years of life lost (AYLL) and potential years of life lost rate (PYLLR). ResultsThe majority of patients who died from severe mental disorders were those with schizophrenia, accounting for 77.68% (2 826/3 638). The most common cause of death among patients with severe mental disorders was physical illness with 1 869 cases (51.37%). Among the selected subjects, patients with mental retardation and comorbid mental disorders had the youngest age of disease onset [(22.49±20.14) years], the youngest age at death [(51.72±18.32) years] and the longest duration of disease [(29.26±19.35) years]. The PYLL, AYLL and PYLLR of patients with severe mental disorders in Jining were 68 941.06 person-years, 18.95 years and 382.36‰, respectively. The mental retardation and comorbid mental disorders had the highest AYLL at 27.21 years, and epilepsy-induced mental disorder had the highest PYLLR at 892.73‰. ConclusionComorbid physical illness is the main causes of death in patients with severe mental disorders in Jining city, and epilepsy-induced mental disorder have occupied the first place in terms of the years of life lost.

RÉSUMÉ

OBJECTIVE@#To investigate the clinicopathological characteristics of anorectal mucosal melanoma (ARMM), and to evaluate the prognostic factors.@*METHODS@#A total of 68 primary ARMM surgical specimens from 2010 to 2018 were retrospectively studied. Slides were reviewed to evaluate pathological features. Slingluff staging method was used for staging.@*RESULTS@#(1) Clinical features: The median age at diagnosis in this group was 61.5 years, with a male-to-female ratio 1 ∶1.62. The most common complaint was blooding (49 cases). For anatomic site, anorectum was the prevalent (66.2%), followed by rectum (20.6%). At the time of diagnosis, 28 cases were stage Ⅰ (localized stage, 41.2%), 25 cases were stage Ⅱ (regional lymph node metastasis, 36.8%), and 15 cases were stage Ⅲ (distant metastasis, 22.1%). Five patients underwent wide local excision, the rest abdominoperineal resection, and 48 patients received adjuvant therapy after surgery. (2) Pathological features: Grossly 88.2% of the tumors were exophytic polypoid masses, with the median tumor size 3.5 cm and the median tumor thickness 1.25 cm. Depth of invasion below lamina muscularis mucosae ranged from 0-5.00 cm (median 1.00 cm). The deepest site of tumor invasion reached muscular layer in 27 cases, and perirectal tissue in 16 cases. Melanin pigmentation was absent or not obvious in 67.6% of the cases. The predominant cytology was epithelioid (45 cases, 66.2%). The rate for ulceration, necrosis, lymphovascular invasion, and perineural invasion was 89.7%, 35.3%, 55.9%, and 30.9%, respectively. The median mitotic count was 18/mm2. The positive rate of S100, HMB-45 and Melan-A were 92.0%, 92.6% and 98.0%, respectively. The median of Ki-67 was 50%. The incidences of mutations within CKIT, BRAF and NRAS genes were 17.0% (9 cases), 3.8% (2 cases) and 9.4% (5 cases), respectively. (3) Prognosis: Survival data were available in 66 patients, with a median follow-up of 17 months and a median survival time of 17.4 months. The 1-year, 2-year and 5-year overall survival rate was 76.8%, 36.8% and 17.2%, respectively. The rate of lymphatic metastasis at diagnosis was 56.3%. Forty-nine patients (84.5%) suffered from distant metastasis, and the most frequent metastatic site was liver. Univariate analysis revealed that tumor size (>3.5 cm), depth of invasion below lamina muscularis mucosae (>1.0 cm), necrosis, lymphovascular invasion, BRAF gene mutation, lack of adjuvant therapy after surgery, deep site of tumor invasion, and high stage at diagnosis were all poor prognostic factors for overall survival. Multivariate model showed that lymphovascular invasion and BRAF gene mutation were independent risk factors for lower overall survival, and high stage at diagnosis showed borderline negative correlation with overall survival.@*CONCLUSION@#The overall prognosis of ARMM is poor, and lymphovascular invasion and BRAF gene mutation are independent factors of poor prognosis. Slingluff staging suggests prognosis effectively, and detailed assessment of pathological features, clear staging and genetic testing should be carried out when possible. Depth of invasion below lamina muscularis mucosae of the tumor might be a better prognostic indicator than tumor thickness.

AIM:To investigate the neuroprotective effect of 17β-estradiol(E2)on retina light damage in BALB/c and C57BL/6 mice and provide experimental data for the successful construction of a research model for E2 against retinal light damage.METHODS:Totally 40~45 adult female BALB/c or C57BL/6 mice were divided into six groups, 6 for each group: normal control, ovariectomized control, ovariectomized light(mice were stimulated with continuous white light at 10000 lx for 4, 8, 12, 16, and 24h after 14d of ovariectomy), intravitreal administration sham operation, saline and E2 pre-treatment groups(2μL saline or 10-5mol/L E2 were intravitreal injected respectively after 14d of ovariectomy operation and 24h of dark adaptation). The morphological and functional changes of the retina were detected by paraffin section HE staining, TUNEL staining and electroretinogram.RESULTS:In the ovariectomized light group, the thickness of the inner/outer nuclear layer decreased significantly from the 4h stimulation of 10000 lx white light group. Intravitreal administration of E2 significantly inhibited the apoptosis of retinal cells in the two strains of mice(P&#x003C;0.01)and the decrease of amplitudes of a- and b-waves in max-ERG of C57BL/6 mice(P&#x003C;0.05).CONCLUSION:The light loss sensitivity of two strains of mice was different under the same light stimulation. E2 had a protective effect on both morphology and function of the retina in BALB/c mice, and had a significant protective effect on retina function in C57BL/6 mice.

OBJECTIVE@#To observe the effects of moxibustion on the stem cell factor (SCF)/tyrosine kinase receptor (c-kit) signaling pathway and immune function in rats with diarrhea irritable bowel syndrome (IBS-D), and to explore the mechanism of moxibustion for IBS-D.@*METHODS@#Among 52 young rats born from 6 healthy pregnant SPF rats, 12 rats were randomly selected into the normal group, and the remaining 40 rats were treated with the three-factor combination method of maternal separation, acetic acid enema and chronic restraint stress to establish the IBS-D rat model. Thirty-six rats with successful IBS-D model were randomly divided into a model group, a moxibustion group, and a medication group, 12 rats in each group. The rats in the moxibustion group were treated with suspension moxibustion at "Tianshu" (ST 25) and "Shangjuxu" (ST 37); the rats in the medication group were treated with intragastric administration of rifaximin suspension (150 mg/kg). All the treatments were given once a day for 7 consecutive days. The body mass, loose stool rate (LSR), the minimum volume threshold when abdominal withdrawal reflex (AWR) scored 3 were measured before acetic acid enema (35 days old), after modeling (45 days old), and after intervention (53 days old). After intervention (53 days old), HE staining was used to observe the morphology of colon tissue, and spleen and thymus coefficients were measured; ELISA method was used to detect serum inflammatory factors (tumor necrosis factor a [TNF-a], interleukin [IL]-10, IL-8), T-lymphocyte subsets (CD+4, CD+8, CD+45), value of CD+4/CD+8 and immune globulin (IgA, IgG, IgM); real-time PCR method and Western blot method was used to detect the expression of SCF, c-kit mRNA and protein in colon tissue; immunofluorescence staining method were used to detect positive expression of SCF and c-kit.@*RESULTS@#After intervention, compared with the normal group, in the model group, the body mass and the minimum volume threshold when AWR scored 3 were decreased (P<0.01), LSR, spleen and thymus coefficients, serum levels of TNF-α, IL-8, CD+4, CD+45, CD+4/CD+8, IgA, IgG, IgM were increased (P<0.01), serum IL-10 level and protein and mRNA expression of SCF and c-kit in colon tissue were decreased (P<0.01), and the positive expression of SCF and c-kit was decreased (P<0.01). Compared with the model group, in the moxibustion group and the medication group, the body mass and the minimum volume threshold when AWR scored 3 were increased (P<0.01, P<0.05), LSR, spleen and thymus coefficients, serum levels of TNF-α, IL-8, CD+4, CD+8, CD+45, CD+4/CD+8, IgA, IgG, IgM were decreased (P<0.01, P<0.05), serum IL-10 level and protein and mRNA expression of SCF and c-kit in colon tissue were increased (P<0.01), and the positive expression of SCF and c-kit was increased (P<0.01). Compared with the medication group, in the moxibustion group, the level of serum CD+4 was decreased (P<0.05), the value of CD+4/CD+8 was increased (P<0.01), and there was no significant difference in other indexes (P>0.05). The expression of SCF and c-kit mRNA was positively correlated with the minimum volume threshold when AWR scored 3 and IL-10 (P<0.01), and negatively correlated with remaining indexes (P<0.01, P<0.05).@*CONCLUSION@#Moxibustion could reduce visceral hypersensitivity, improve symptoms of abdominal pain and diarrhea in IBS-D rats, and its mechanism may be related to up-regulation of the expression of SCF/c-kit signaling pathway and improvement of IBS-D immune function.

RÉSUMÉ

OBJECTIVE@#To observe the effect of Tongdu Tiaoshen (promoting the circulation of the governor vessel and regulating the spirit) electroacupuncture (EA) pretreatment on pyroptosis mediated by peroxisome proliferators-activated receptor γ (PPARγ) of the cerebral cortex in rats with cerebral ischemia reperfusion injury (CIRI) and explore the potential mechanism of EA for the prevention and treatment of CIRI.@*METHODS@#A total of 110 clean-grade male SD rats were randomly divided into a sham-operation group, a model group, an EA group, an EA + inhibitor group and an agonist group, 22 rats in each group. In the EA group, before modeling, EA was applied to "Baihui" (GV 20), "Fengfu" (GV 16) and "Dazhui" (GV 14), with disperse-dense wave, 2 Hz/5 Hz in frequency, 1 to 2 mA in intensity, lasting 20 min; once a day, consecutively for 7 days. On the base of the intervention as the EA group, on the day 7, the intraperitoneal injection with the PPARγ inhibitor, GW9662 (10 mg/kg) was delivered in the EA + inhibitor group. In the agonist group, on the day 7, the PPARγ agonist, pioglitazone hydrochloride (10 mg/kg) was injected intraperitoneally. At the end of intervention, except the sham-operation group, the modified thread embolization method was adopted to establish the right CIRI model in the rats of the other groups. Using the score of the modified neurological severity score (mNSS), the neurological defect condition of rats was evaluated. TTC staining was adopted to detect the relative cerebral infarction volume of rat, TUNEL staining was used to detect apoptosis of cerebral cortical nerve cells and the transmission electron microscope was used to observe pyroptosis of cerebral cortical neural cells. The positive expression of PPARγ and nucleotide-binding to oligomerization domain-like receptor protein 3 (NLRP3) in the cerebral cortex was detected with the immunofluorescence staining. The protein expression of PPARγ, NLRP3, cysteinyl aspartate specific protease-1 (caspase-1), gasdermin D (GSDMD) and GSDMD-N terminal (GSDMD-N) in the cerebral cortex was detected with Western blot. Using the quantitative real-time fluorescence-PCR, the mRNA expression of PPARγ, NLRP3, caspase-1 and GSDMD of the cerebral cortex was detected. The contents of interleukin (IL)-1β and IL-18 in the cerebral cortex of rats were determined by ELISA.@*RESULTS@#Compared with the sham-operation group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were increased (P<0.01), pyroptosis was severe, the protein and mRNA expression levels of PPARγ, NLRP3, caspase-1 and GSDMD were elevated (P<0.01); and the protein expression of GSDMD-N and contents of IL-1β and IL-18 were increased (P<0.01) in the model group. When compared with the model group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were decreased (P<0.01), pyroptosis was alleviated, the protein and mRNA expression levels of PPARγ were increased (P<0.01), the protein and mRNA expression levels of NLRP3, caspase-1 and GSDMD were decreased (P<0.01), the protein expression of GSDMD-N was reduced (P<0.01); and the contents of IL-1β and IL-18 were lower (P<0.01) in the EA group and the agonist group; while, in the EA + inhibitor group, the protein expression of PPARγ was increased (P<0.01), the protein and mRNA expression levels of NLRP3 and GSDMD were decreased (P<0.01, P<0.05), the mRNA expression of caspase-1 was reduced (P<0.01); and the contents of IL-1β and IL-18 were lower (P<0.01). When compared with the EA + inhibitor group, the mNSS, the relative cerebral infarction volume and the TUNEL positive cells rate were decreased (P<0.05, P<0.01), pyroptosis was alleviated, the protein and mRNA expression levels of PPARγ were increased (P<0.01), the protein and mRNA expression levels of NLRP3, caspase-1 and GSDMD were decreased (P<0.01), the protein expression of GSDMD-N was reduced (P<0.01); and the contents of IL-1β and IL-18 were declined (P<0.01) in the EA group. Compared with the agonist group, in the EA group, the relative cerebral infarction volume and the TUNEL positive cells rate were increased (P<0.05, P<0.01), the mRNA expression of PPARγ was decreased (P<0.01) and the protein expression of GSDMD-N was elevated (P<0.05); and the contents of IL-1β and IL-18 were higher (P<0.01).@*CONCLUSION@#Tongdu Tiaoshen EA pretreatment can attenuate the neurological impairment in the rats with CIRI, and the underlying mechanism is related to the up-regulation of PPARγ inducing the inhibition of NLRP3 in the cerebral cortex of rats so that pyroptosis is affected.

RÉSUMÉ

OBJECTIVES@#To explore the effect of acupuncture and moxibustion on intestinal flora in the rats with diarrhea-predominant irritable bowel syndrome (IBS-D) based on 16S rDNA technique.@*METHODS@#Ten rats were randomized from 58 SPF-grade male SD rats to be the blank group. The remained 48 rats were prepared to be IBS-D models by the modified method of acetic acid enema combined with binding tail-clip stress. Forty successfully-modeled rats were randomly divided into a model group, an acupuncture group, a moxibustion group and a western medication group, with 10 rats in each one. In the acupuncture group, the needle was inserted at bilateral "Zusanli" (ST 36) and remained for 15 min in each rat. In the moxibustion group, the suspending moxibustion was delivered at bilateral "Zusanli" (ST 36) for 15 min. The rats in the western medication group were given pinaverium bromide suspension (10 mL/kg) by intragastric administration. The above interventions were performed once daily for consecutive 14 days. The body mass and the score of fecal trait were compared before and after modeling, as well as after intervention in each group. Fecal water content, diarrhea index and colon transit time (CTT) were measured after modeling and intervention in the rats of each group separately. After intervention, the colonic morphology of rats in each group was observed, and using 16S rDNA technique, the intestinal flora was detected.@*RESULTS@#After modeling, compared with the blank group, the body mass and CTT were reduced (P<0.01); fecal trait scores, fecal water contents and diarrhea index increased (P<0.01) in the other 4 groups. After intervention, the body mass and CTT of the rats decreased (P<0.01), and fecal trait score, fecal water content and diarrhea index increased (P<0.01) in the model group compared with those in the blank group. In the acupuncture group, the moxibustion group and the western medication group, when compared with the model group, the body mass and CTT were elevated (P<0.01), while fecal trait scores, fecal water contents and diarrhea index declined (P<0.01). Compared with the western medication group, fecal water content decreased in the acupuncture group and the moxibustion group (P<0.05), while CTT increased in the acupuncture group (P<0.01), the body mass increased and fecal trait score was dropped in the moxibustion group (P<0.05). The colonic mucosa structure was clear and complete, and there was no obvious inflammatory cell infiltration in the blank group. The mild interstitial edema of intestinal mucosa was presented with the infiltration of few inflammatory cells in the model group. There was the infiltration of few inflammatory cells in the mucosa of the acupuncture group, the moxibustion group and the western medication group. Compared with the blank group, the indexes of Richness, Chao1, ACE and Shannon decreased in the model group (P<0.05). Indexes of Richness, Chao1 and ACE increased in the acupuncture group and the moxibustion group (P<0.05), and the Richness index in the western medication group increased (P<0.05) when compared with those in the model group. The relative abundance of Bacteroidetes, Proteobacteria and Prevotella increased (P<0.05), and that of Firmicutes and Muribaculaceae decreased (P<0.05) in the model group compared with those in the blank group. When compared with the model group, the relative abundance of Bacteroidetes, Proteobacteria and Prevotella was reduced (P<0.05), while that of Firmicutes and Muribaculaceae increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group; and that of Actinobacteria and Bifidobacterium increased in the acupuncture group and the moxibustion group (P<0.05). Compared with the blank group, the relative abundance of lipopolysaccharide (LPS) biosynthesis was elevated (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis decreased (P<0.05) in the model group. The relative abundance of LPS biosynthesis was dropped (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group compared with those of the model group.@*CONCLUSIONS@#Either acupuncture or moxibustion can relieve the symptoms of IBS-D and protect intestinal mucosa, which may be associated with regulating the structure of intestinal flora and promoting nutrient metabolism and biosynthesis.

RÉSUMÉ

Objective: To analyze the incidence and related factors of drug resistance in HIV-infected pregnant and postpartum women in some areas of three western provinces of China from 2017 to 2019. Methods: From April 2017 to April 2019, face-to-face questionnaires and blood sample testing were conducted in all health care institutions providing maternal and perinatal care and midwifery-assisted services in 7 prevention of mother-to-child transmissi project areas in Xinjiang, Yunnan and Guangxi provinces/autonomous regions. Information was collected during the perinatal period and viral load, CD4+T lymphocytes and drug resistance genes were detected at the same time. The multivariate logistic regression model was used to analyze the relationship between different factors and drug resistance in HIV-infected pregnant and postpartum women. Results: A total of 655 HIV-infected pregnant and postpartum women were included in this study. The incidence of drug resistance was 3.4% (22/655), all of whom were cross-drug resistant. The rate of low, moderate and high drug resistance was 2.1% (14/655), 1.2% (8/655) and 0.8% (5/655), respectively. The drug resistance rate in the people who had previously used antiviral drugs was 1.9% (8/418), and the drug resistance rate in the people who had not used drugs was 5.9% (14/237). The NNRTI drug resistance accounted for 2.8% (18/655) and the NRTI drug resistance rate was 2.5% (16/655). The multivariate logistic regression model showed that the risk of HIV resistance was lower in pregnant women who had previously used antiviral drugs (OR=0.32, 95%CI: 0.11-0.76). Conclusion: Strengthening the management of antiviral drug use and focusing on pregnant and postpartum women who have not previously used antiviral drugs can help reduce the occurrence of drug-resistant mutations. Personalized antiviral therapy should be considered to achieve viral inhibition effects in clinical practice.

RÉSUMÉ

Objective: To analyze the incidence and related factors of drug resistance in HIV-infected pregnant and postpartum women in some areas of three western provinces of China from 2017 to 2019. Methods: From April 2017 to April 2019, face-to-face questionnaires and blood sample testing were conducted in all health care institutions providing maternal and perinatal care and midwifery-assisted services in 7 prevention of mother-to-child transmissi project areas in Xinjiang, Yunnan and Guangxi provinces/autonomous regions. Information was collected during the perinatal period and viral load, CD4+T lymphocytes and drug resistance genes were detected at the same time. The multivariate logistic regression model was used to analyze the relationship between different factors and drug resistance in HIV-infected pregnant and postpartum women.

RÉSUMÉ

OBJECTIVE@#To investigate the mechanism by which Chinese medicine Shengmai Yin (SMY) reverses epithelial-mesenchymal transition (EMT) through lipocalin-2 (LCN2) in nasopharyngeal carcinoma (NPC) cells CNE-2R.@*METHODS@#Morphological changes in EMT in CNE-2R cells were observed under a microscope, and the expressions of EMT markers were detected using quantitative real-time PCR (RT-qPCR) and Western blot assays. Through the Gene Expression Omnibus dataset and text mining, LCN2 was found to be highly related to radiation resistance and EMT in NPC. The expressions of LCN2 and EMT markers following SMY treatment (50 and 100 µ g/mL) were detected by RT-qPCR and Western blot assays in vitro. Cell proliferation, migration, and invasion abilities were measured using colony formation, wound healing, and transwell invasion assays, respectively. The inhibitory effect of SMY in vivo was determined by observing a zebrafish xenograft model with a fluorescent label.@*RESULTS@#The CNE-2R cells showed EMT transition and high expression of LCN2, and the use of SMY (5, 10 and 20 µ g/mL) reduced the expression of LCN2 and reversed the EMT in the CNE-2R cells. Compared to that of the CNE-2R group, the proliferation, migration, and invasion abilities of SMY high-concentration group were weakened (P<0.05). Moreover, SMY mediated tumor growth and metastasis in a dose-dependent manner in a zebrafish xenograft model, which was consistent with the in vitro results.@*CONCLUSIONS@#SMY can reverse the EMT process of CNE-2R cells, which may be related to its inhibition of LCN2 expression. Therefore, LCN2 may be a potential diagnostic marker and therapeutic target in patients with NPC.

RÉSUMÉ

Objective: To construct a prediction model of pathologic complete response (pCR) in locally advanced rectal cancer patients who received programmed cell death protein-1 (PD-1) antibody and total neoadjuvant chemoradiotherapy by using radiomics based on MR imaging data and to investigate its predictive value. Methods: A clinical diagnostic test study was carried out. Clinicopathalogical and radiological data of 38 patients with middle-low rectal cancer who received PD-1 antibody combined with total neoadjuvant chemoradiotherapy and underwent TME surgery from January 2019 to September 2021 in our hospital were retrospectively collected. Among 38 patients, 23 were males and 15 were females with a median age of 68 (47-79) years and 13 (34.2%) a chieved pCR. These 38 patients were stratified and randomly divided into the training group (n=26) and test group (n=12) for modeling. All the patients underwent rectal MRI before treatment. The clinical, imaging and radiomics features of all the patients were collected, and the clinical feature model and radiomics model were constructed. The receiver operating characteristic (ROC) curves of each model were drawn, and the constructed model was evaluated through the area under the curve (AUC), accuracy, sensitivity, specificity, positive predictive value and negative predictive value. Results: There were no significant differences in age, gender, primary location of tumor and postoperative pathology between the two groups (all P>0.05). Forty-one features were extracted from region of interest in each modality, including 9 first-order features, 24 gray level co-occurrence matrix features and 8 shape features. From 38 patients, 41 features were extracted from each imaging modality of baseline and preoperative DWI and T2WI images, totally 164 features. Only 4 features were preserved after correlation analysis between each pair of features and t-test between pCR and non-pCR subjects. After LASSO cross validation, only the first-order skewness of the baseline DWI image before treatment and the volume in the baseline T2WI image before treatment were retained. The area under the curve, sensitivity, specificity, positive and negative predictive values of the prediction model established by applying these two features in the training group and the test group were 0.856 and 0.844, 77.8% and 100.0%, 88.2% and 75.0%, 77.8% and 66.7%, 88.2% and 100.0%, respectively. The decision curve analysis of the radiomics model showed that the strategy of this model in predicting pCR was better than that in treating all the patients as pCR and that in treating all the patients as non-pCR. Conclusion: The pCR prediction model for rectal cancer patients receiving PD-1 antibody combined with total neoadjuvant radiochemotherapy based on MRI radiomics has the potential to be used in clinical screening or rectal cancer patients who can be spared from radical surgery.

The remaining rats were made into IBS-D model. A total of 36 rats with successful model were randomly divided into a model group, a medication group and a moxibustion group, 12 rats in each group. The rats in the medication group were intraperitoneally injected with pyrrolidine dithiocarbamate (PDTC). The rats in the moxibustion group were treated with moxibustion at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) for 20 min each time. All the intervention was given once a day for 7 days. Before and after modeling as well as after intervention, the body mass, loose stool rate and the minimum volume threshold of abdominal withdrawal reflex (AWR) were measured. After intervention, the contents of serum tumor necrosis factor α (TNF-α), interleukin (IL)-1β and IL-8 were detected by ELISA method; the morphology of colon tissues was observed by HE staining, and the expressions of miR-155, miR-125b, miR-29b, miR-31, miR-18a and NF-κB p65 mRNA in colon tissues were detected by real-time PCR. The expressions of NF-κB p65, TNF-α, IL-1β and IL-8 protein in colon tissues were detected by immunofluorescence.@*RESULTS@#After modeling, the body mass and the minimum volume threshold of AWR in the model group were lower than those in the normal group (P<0.01); the rates of loose stool in the model group were higher than those in the normal group (P<0.01); after intervention, in the model group, the inflammatory infiltration of colon tissues was obvious, and the serum levels of TNF-α, IL-1 β, IL-8 were higher than those in the normal group (P<0.05); the expression of miR-155, miR-125b, miR-29b, miR-31, miR-18a and NF-κB p65 mRNA in colon tissues was higher than that in the normal group (P<0.05); the protein expression of NF-κB p65, TNF-α, IL-1β, IL-8 was also higher than that in the normal group (P<0.01). After intervention, the body mass and the minimum volume threshold of AWR in the medication group and the moxibustion group were both higher than those in the model group (P<0.05); the loose stool rate in the medication group and the moxibustion group were lower than those in model group (P<0.05); the inflammatory cells infiltration in the colon tissues was less, the serum levels of TNF-α, IL-1β and IL-8 as well as the protein expression of NF-κB p65, TNF-α, IL-1β and IL-8 in the colon tissues in the medication group and the moxibustion group were lower than those in the model group (P<0.05, P<0.01). The expression of miR-125b, miR-31, miR-18a and NF-κB p65 mRNA in the medication group were lower than those in the model group (P<0.05). The expression of miR-155, miR-125b, miR-29b, miR-31, miR-18a and NF-κB p65 mRNA in the moxibustion group were lower than those in the model group (P<0.05). The miR-155, miR-125b, miR-29b, miR-31, miR-18a were positively correlated with NF-κB p65 mRNA (0<r<1, P<0.01).@*CONCLUSION@#The anti-inflammatory mechanism of moxibustion at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) for IBS-D rats may be related to regulating multiple miRNAs to inhibit NF-κB signal pathway and reduce the expression of inflammatory factors.

Objective: To explore the mechanism of An-Pressing manipulation in relieving energy crisis in chronic myofascial trigger points (MTrPs) by observing the effects of An-Pressing manipulation on adenosine triphosphate (ATP), adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK)/peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) pathway and mitochondrial ultrastructure of skeletal muscle cells in MTrPs rats. Methods: Forty-eight male Sprague-Dawley rats were randomly divided into a blank group, a model group, a lidocaine group, and an An-Pressing manipulation group, with 12 rats in each group. The model group, lidocaine group and An-Pressing manipulation group were used to replicate the MTrPs rat model by blunt shock and centrifugal motion method. After modeling, the An-Pressing manipulation group was subjected to 7 times An-Pressing manipulation, once every other day; the lidocaine group was treated with 3 times of injection of lidocaine at the MTrPs, once every 6 d. The blank group and the model group were fed normally without intervention. After the intervention, local muscle tissue was taken to detect the content of ATP and the expression of AMPK, phosphorylated AMPK (phospho-AMPK), PGC-1α, and glucose transporter 4 (GluT4), and the ultrastructure of mitochondria was observed under an electron microscope. Results: Compared with the blank group, the ATP content in the model group was decreased (P<0.05), the protein expression levels of phospho-AMPK, PGC-1α, and GluT4 and the ratio of phospho-AMPK to AMPK were decreased (P<0.05); under the electron microscope, the number of mitochondria decreased, and they were deformed, small in volume, and had deformed cristae. Compared with the model group, the ATP contents in the An-Pressing manipulation group and the lidocaine group were increased (P<0.05), and the protein expression levels of phospho-AMPK, PGC-1α, and GluT4 and the ratio of phospho-AMPK to AMPK were increased (P<0.05); under the electron microscope, the number of mitochondria increased, the shape and size of the mitochondria were basically normal, and the cristae could be seen. Compared with the lidocaine group, phospho-AMPK and the ratio of phospho-AMPK to AMPK in the An-Pressing manipulation group were increased (P<0.05); under the electron microscope, the numbers of mitochondria were similar, and the shape and size of the mitochondria were basically normal without swelling, and the cristae could be observed. Conclusion: An-Pressing manipulation can increase the ATP content in MTrPs tissue, improve the expression levels of PGC-1α and GluT4 proteins and the ratio of phospho-AMPK to AMPK; its mechanism may relate to the activation of AMPK/PGC-1α signaling pathway to promote the repair of mitochondrial damages.

RÉSUMÉ

Objective To investigate the mechanism of action of integrin α4 (ITGA4) in liver fibrosis based on the anti-liver fibrosis effect of sticky sugar amino acid (SSAA) in rats. Methods A rat model of liver fibrosis was induced by intraperitoneal injection of CCl 4 , and then colchicine and low-, middle-, and high-dose SSAA were used for intervention, with blank control group and SSAA group as control. After 12 weeks of experimental intervention, serum and liver samples were collected to measure the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and HE staining and Sirius Red staining were used to observe the pathological conditions of liver tissue; quantitative real-time PCR was used to measure the transcriptional level of ITGA4, integrin β1 (ITGB1), transforming growth factor-β1 (TGFβ1), alpha-smooth muscle actin (α-SMA), and TIMP2 in liver tissue; Western blot was used to measure the relative protein expression levels of ITGA4, ITGB1, TGFβ1, α-SMA, MMP2, TIMP1, and TIMP2; immunohistochemistry was used to observe the protein expression of TGFβ1 and α-SMA. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t -test was used for comparison between two groups. Results There were significant increases in AST and ALT in the CCl 4 model group, and intervention with colchicine or low-, middle-, and high-dose SSAA reduced the levels of AST and ALT, with a significant difference between the CCl 4 model group and the other groups (all P < 0.05). HE staining and Sirius Red staining showed disordered structure of hepatic lobules and an increase in collagen fibers in the CCl 4 model group, and the structure of hepatic lobules was improved after intervention with colchicine or low-, middle-, and high-dose SSAA. The CCl 4 model group had significantly higher transcriptional levels of ITGA4, TGFβ1, α-SMA, and TIMP2 than the other groups, and there were significant reductions in the transcriptional levels of each factor after intervention with colchicine or SSAA, with a significant difference between the CCl 4 model group and the other groups (all P < 0.05). The CCl 4 model group had significantly higher protein expression levels of ITGA4, TGFβ1, α-SMA, TIMP2, and TIMP1 and a significantly lower protein expression level of MMP2 than the other groups, and intervention with colchicine or SSAA inhibited the expression of ITGA4, TGFβ1, α-SMA, TIMP2, and TIMP1 and promoted the expression of MMP2. Immunohistochemistry showed that the CCl 4 model group had significantly higher expression levels of TGFβ1 and α-SMA than the other groups, which was inhibited by intervention with colchicine or SSAA. The high-dose SSAA group had the most significant effect in reducing aminotransferases, improving lobular structure, and inhibiting the protein expression of liver fibrosis factors. Conclusion The high expression of ITGA4 in the liver is associated with the development of liver fibrosis, which is consistent with the increases in the expression of TGFβ1 and α-SMA. Inhibiting the expression of ITGA4 can provide more therapeutic targets for liver fibrosis and expand the anti-liver fibrosis mechanism of SSAA.
