ABSTRACT
Objective:To explore the relationship and mechanism among job stressors, perceived professional benefits and humanistic practice ability in midwives, so as to provide reference for the training and management of midwives.Methods:Used the convenient sampling method to conduct a cross-sectional survey on 216 midwives in 6 comprehensive or specialized hospitals in Zhejiang Province by using Stressor Scale, Perceived Professional Benefits Questionnaire and Humanistic Practice Ability Scale from May to September 2020. The mediating effect was analyzed on the basis of the current situation analysis and correlation analysis.Results:The total scores of humanistic practice ability, job stressors and perceived professional benefits of midwives were (102.13 ± 25.91), (72.77 ± 14.49) and (138.23 ± 18.71) respectively. The job stressors of midwives were negatively correlated with humanistic practice ability ( r=-0.206, P<0.01), perceived professional benefits were positively related to humanistic practice ability ( r=0.289, P<0.001) and were negatively correlated with job stressors ( r=-0.507, P<0.001). Perceived professional benefits played a major mediating role in the influence of stressors on humanistic practice ability (the total standardized effect was -0.233, and the indirect effect was -0.144). Conclusions:Perceived professional benefits act as a main mediator between job stressors and humanistic practice ability in midwives. Managers should reduce job stressors, enhance perceived professional benefits, and promote the formation, development and practice of humanistic practice ability of midwives.
ABSTRACT
Endoscopic data of 108 upper gastrointestinal elevated lesions caused by vascular or hemangioma compression by endoscopic ultrasonography (EUS) at the Second Affiliated Hospital of Soochow University, Changshu No.1 People's Hospital, Kushan Hospital of Chinese Medicine and Traditional Chinese Medicine Hospital of Changshu from December 2010 to June 2019 were retrospectively summarized. The results showed that lesions were mainly located in the esophagus [50.9% (55/108)] and stomach [47.2% (51/108)], especially in the middle [40.0% (22/55)] and upper esophagus [36.4% (20/55)], body [66.7% (34/51)] and fundus of stomach [31.4% (16/51)], respectively. The major etiology included splenic artery and aneurysm compression [29.6% (32/108)], aortic compression [23.1% (25/108)], isolated esophageal venous aneurysm compression [13.9% (15/108)] and gastric submucosal vein and venous aneurysm compression [12.0% (13/108)], with diverse endoscopic presentation. The above results suggest that elevated lesions of upper gastrointestinal tract caused by blood vessels and hemangiomas are mostly due to external vascular pressure outside the lumen, but ectopic submucosal arteries and isolated phlebangioma are not uncommon. The lesions are widely distributed with different gastroscopic manifestations. EUS is important for definite diagnosis, and can be combined with color Doppler technique, CT plain scan and angiographic reconstruction if necessary.
ABSTRACT
Hypervirulent Klebsiella pneumoniae (HvKP) is a new variant of Klebsiella pneumoniae. It is characterized by strong virulence and easy dissemination. It mainly causes liver abscess with multiple invasive infections, including eye, lung and central nervous system, with a high fatality rate. A case of severe intracranial infection caused by HvKP was reported. The patient was a 44-year-old formerly healthy man. He had acute onset of fever, headache, and disturbance of consciousness, which rapidly progressed to intracranial hypertension and respiratory failure. Cerebrospinal fluid examination suggested purulent infection, and bacterial culture suggested Klebsiella pneumoniae, which was sensitive to other commonly used antibiotics except ampicillin. Brain magnetic resonance imaging showed multiple abnormal signals in bilateral frontal, parietal and temporal lobes, right centrum semiovale, bilateral corona radiata, basal ganglia, thalamus and insula, as well as enhancement of meningeal and ependymal membrane, and swelling of brain tissue. During hospitalization, the patient developed a blood stream infection of pan-drug-resistant Klebsiella pneumoniae and was in critical condition. After aggressive treatment, the patient was cured and discharged from the hospital. After half a year follow-up, his prognosis was good and his social function was restored. The clinical data, diagnosis and treatment of the patient were reported and the literature was reviewed to provide clinical reference for the disease.
ABSTRACT
ObjectiveTo predict the potential targets and mechanism of Jingfang mixture in the treatment of H1N1 influenza and provide references for clinical application of Jingfang mixture. MethodThe active components and targets of Jingfang mixture against H1N1 influenza were screened out by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP），SwissTargetPrediction， and TargetNet. The targets of H1N1 influenza were obtained from GeneCards，Online Mendelian Inheritance in Man （OMIM）， and DisGeNET and standardized by UniProt KB. The intersection targets were obtained by Venny 2.1.0. The "drug-component-target" network was constructed with Cytoscape 3.2.1 and analyzed for the topological attributes. The intersection targets were uploaded to STRING 11.5 to obtain the protein-protein interaction （PPI） network. Gene Ontology （GO） enrichment analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） analysis were carried out by Metascape. Finally，the top active components ranked by degree were docked to the core targets by Autodock vina and visually analyzed by PyMOL. Balb/c female rats were used for experimental verification. Hematoxylin-eosin（HE） staining was used to observe the pathological changes in lung tissues. Enzyme-linked immunosorbent assay（ELISA）was used to detect the levels of tumor necrosis factor-α（TNF-α），interleukin-10（IL-10）， and interleukin-17（IL-17）. Real-time fluorescence-based quantitative polymerase chain reaction（Real-time PCR） and Western blot were used to detect the mRNA and protein expression levels in lung tissues. ResultThere were 144 active components in Jingfang mixture. A total of 421 target genes of Jingfang mixture and 2 956 targets of H1N1 influenza were identified，including 199 common targets. Topological analysis showed that the core components of Jingfang mixture against H1N1 influenza included quercetin，luteolin， and kaempferol，and the core targets included prostaglandin-endoperoxide synthase 2（PTGS2），estrogen receptor alpha（ESR1），inducible nitric oxide synthase 2（iNOS2），peroxisome proliferator-activated receptorγ（PPARγ），and cyclooxygenase-1（PTGS1）. GO enrichment yielded 697 items in biological process （BP） （P<0.01）， 59 items in molecular function （MF）（P<0.01）， and 21 items in cellular component （CC） （P<0.01）. A total of 132 signaling pathways （P<0.01） were obtained by KEGG enrichment analysis， including phosphatidylinositol 3-kinases（PI3K）/protein kinase B（Akt） signaling pathway and mitogen-activated protein kinase（MAPK） signaling pathway，most of which were related to the regulation of immune inflammation. Molecular docking showed that the binding energy of the active components of Jingfang mixture to the core targets was less than -5.0 kcal·mol-1，indicating good binding activity. HE staining showed that the lung tissues were significantly improved after drug intervention，and Real-time PCR and Western blot showed that Jingfang mixture could reduce the mRNA and protein expression of PI3K and Akt in lung tissues. ConclusionJingfang mixture can play an anti-viral effect against the influenza A virus through multiple components，multiple targets， and multiple pathways. The active components quercetin，luteolin， and kaempferol may control the inflammation and regulate immunity on the PI3K/Akt，MAPK， and other signaling pathways by acting on targets such as PTGS2，ESR1，iNOS2，PPARγ， and PTGS1.
ABSTRACT
ObjectiveTo observe the effect of classical prescription Gegen Qinliantang（GGQLT） on inflammatory factors and key targets in the inflammatory pathways mediated by lipopolysaccharide in KKAy mice and explore its mechanism in improving spontaneous type 2 diabetes mellitus （T2DM）. MethodSixty-five SPF KKAy mice with spontaneous T2DM and 13 C57BL/6J mice （control） were selected in the barrier system and fed on a high-fat diet. The model was properly induced in 44 mice in the context of random blood glucose exceeding or equal to 13.9 mmol·L-1. Then the mice were assigned into a normal group （20 mL∙kg-1 normal saline）， a model group （20 mL∙kg-1 normal saline）， an acarbose group （3.9 mg∙kg-1）， and high- and low-dose GGQLT groups （1.82 and 0.45 g∙kg-1）， with 11 mice in each group. The mice in each group were treated correspondingly by gavage for eight weeks， once per day. Blood glucose and body weight were systematically evaluated. Twelve hours after the last administration， blood samples were collected from the eyes， and the serum and muscle and liver tissues were extracted. The levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and glucose transporter type 4 （GluT4） were detected by semi-quantitative enzyme-linked immunosorbent assay （ELISA）. The protein expression of IκB kinase β （IKKβ） and nuclear factor-κB （NF-κB） in muscle tissues and Toll-like receptor 4 （TLR4） in liver tissues was detected by Western blot. ResultCompared with the normal group， the model group showed increased body weight and blood glucose （P<0.01）. Compared with the model group， the acarbose group and the GGQLT groups showed reduced body weight and blood glucose （P<0.05， P<0.01）. As revealed by ELISA results， compared with the normal group， the model group showed increased levels of TNF-α and IL-6 （P<0.01） and deceased GluT4 level （P<0.05）. Compared with the model group， the groups with drug treatment showed reduced levels of TNF-α and IL-6 （P<0.05， P<0.01）， and the acarbose group and the high-dose GGQLT group showed increased GluT4 level （P<0.05， P<0.01）. As displayed by Western blot results， compared with the normal group， the model group showed increased protein expression of IKKβ， NF-κB， and TLR4 （P<0.01）. Compared with the model group， the acarbose group and the GGQLT groups showed reduced protein expression of IKKβ， NF-κB， and TLR4 （P<0.05， P<0.01）. ConclusionGGQLT can inhibit the inflammatory cascade effect and improve T2DM by down-regulating the levels of key inflammatory factors in the TLR4 pathway， inhibiting their activation， and increasing the translocation and activity of GluT4 on the basis of the regulation of intestinal flora.
ABSTRACT
ObjectiveTo analyze the clinical application characteristics of prescription preparations for external use in the Chinese pharmacopoeia 2020 edition （hereafter abbreviated as the Pharmacopoeia）. MethodThe topical functions， usage， dosage， dosage form， application method， and prescription of the preparations for external use in the Pharmacopoeia were analyzed. ResultThe Chinese pharmacopoeia 2020 edition includes a total of 138 prescription preparations for external use， the specific clinical usage， dosage， administration method， and efficacy evaluation of which remain unclear. These preparations can be used to treat a wide range of diseases. Specifically， the use in orthopedics and traumatology （36 preparations， accounting for 26.09%） is dominant， followed by that in internal medicine， surgery， and throat. The major application method is directly applying to the diseased area （35 preparations， 25.36%）. The main dosage forms are ointment （40 preparations， 28.99%） and powder （24 preparations， 17.39%） and others include liniments， suppositories， tinctures， and sprays. The clinical usage and dosage of these preparations are mostly unclear. Only 48 preparations （34.78%） are recorded with clear dosage and frequency of use， and 45 preparations （32.61%） have neither clear dosage nor frequency of use. The 138 prescription preparations for external use include 211 single medicines， of which 44 single medicines can be used alone. The single medicines are mostly used for heat clearing （48 preparations， 22.75%）. ConclusionThe Chinese pharmacopoeia 2020 edition （Volume I） records a large number of prescription preparations for external use， and the number shows an increasing trend. However， the usage， dosage， and efficacy evaluation criteria of these preparations remain to be improved and need in-depth research.
ABSTRACT
ObjectiveTo explore the possible mechanism of total flavonoids of peony flower （TFPF） in protecting rats from gouty nephropathy and provide data support for the pharmaceutical research on the treatment of gouty nephropathy. MethodGouty nephropathy rat model was established by adenine combined with ethambutol. Rats were randomly assigned into blank control group， model group， allopurinol （42 mg·kg-1） group， Tongfengshu tablets （600 mg·kg-1， positive control） group， and TFPF （260， 130， and 65 mg·kg-1） groups. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of tumor necrosis factor-α （TNF-α）， monocyte chemoattractant protein-1 （MCP-1）， interleukin-1β （IL-1β）， and interleukin-18 （IL-18） in rat serum and those of transforming growth factor-β1 （TGF-β1） and IL-1β in renal homogenate. Hematoxylin-eosin（HE） staining was carried out for observation of the morphological changes of renal cells. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling （TUNEL） was conducted for observation of the DNA damage in renal cells. The expression of NOD-like receptor protein 3 （NLRP3）， cysteine aspartic acid protease（Caspase）-1 and IL-1β were observed by immunohistochemistry. The expression levels of NLRP3， Caspase-1 and nuclear transcription factor -κB （NF-κB） in renal tissues were detected by Western blot. ResultCompared with blank group， the contents of TNF-α， MCP-1， IL-1β， IL-18， and TGF-β1 in serum of model group were significantly increased （P<0.01）， and the expressions of NLRP3， Caspase-1， NF-κB and IL-1β in kidney of model group were significantly increased （P<0.01）. The renal tissue cells showed cytoplasmic swelling， cell membrane rupture， and the number of nuclear pyknotic fracture increased. The positive rate of TUNEL staining was significantly increased in model group （P<0.01）， and the contents of IL-1β and TGF-β1 in renal tissue homogenate were significantly increased （P<0.01）. Compared with model group， the contents of inflammatory factors TNF-α， IL-1β and IL-18 in serum of rats in TFPF high- and medium-dose groups could be decreased to different degrees （P<0.05， P<0.01）， while the content of MCP-1 in TFPF high-dose group was significantly decreased （P<0.01）. The content of TGF-β1 in renal tissue homogenate in TFPF high- and medium-dose groups was significantly decreased （P<0.05， P<0.01）， and the content of IL-1β in renal tissue homogenate in TFPF medium-dose group was significantly decreased （P<0.01）. HE staining showed that each dose group of TFPF could improve the status of renal tubular epithelial cells， reduce cytoplasmic swelling and the number of nuclear pyknosis to varying degrees. The positive rate of TUNEL staining was decreased （P<0.01） and DNA damage was decreased. The expression of NLRP3， Caspase-1， IL-1β and NF-κB protein in renal tissue cells was inhibited （P<0.05， P<0.01）. ConclusionTFPF protects rats from gouty nephropathy by inhibiting the secretion of inflammatory cytokines. Specifically， it may inhibit the activation of NF-κB and NLRP3/Caspase-1 pathways to reduce the expression， maturation， and release of inflammatory cytokines such as IL-1β and IL-18 and further inhibit pyroptosis， thereby reversing the inflammatory injury of kidney in gouty nephropathy.
ABSTRACT
ObjectiveTo explore the effect and mechanism of Xiaojindan extract （XJD） on macrophage polarization. MethodLipopolysaccharide （LPS） and interleukin-4 （IL-4） were used to induce M1 and M2 polarization of RAW264.7 cells. The influence of 10-80 mg·L-1 XJD on cell proliferation was detected by Cell Counting Kit-8 （CCK-8） assay. Nitric oxide （NO） and interleukin-6 （IL-6） release was explored by Griess assay and enzyme-linked immunosorbent assay （ELISA）， respectively. The mRNA expression of M1 and M2 macrophage markers was measured by real-time quantitative polymerase chain reaction （Real-time PCR）， and the CD206+ expression was determined by flow cytometry. The activation of phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） pathway was analyzed by western blot. Result10-80 mg·L-1 XJD showed no marked cytotoxicity in LPS （0.5 mg·L-1）- or IL-4 （20 μg·L-1）-induced RAW264.7 cells. Compared with the control group， LPS significantly promoted the expression of M1 macrophage markers （P<0.01）， including increased NO and IL-6 release （P<0.01） and upregulated mRNA expression of interleukin-1β （IL-1β）， inducible nitric oxide synthase （iNOS）， cyclooxygenase-2 （COX-2） and tumor necrosis factor-α （TNF-α） （P<0.01）. Compared with LPS-induced group， 20-80 mg·L-1 XJD decreased the release of NO and IL-6 in a dose-dependent manner （P<0.01）， and similarly 10-80 mg·L-1 XJD suppressed the mRNA expression of IL-1β， iNOS， COX-2 and TNF-α （P<0.01）. Compared with the control group， IL-4 obviously increased the expression of M2 macrophage markers （P<0.01）， including increased CD206+ cell population and upregulated mRNA expression of arginine-1 （Arg-1）， interleukin-10 （IL-10）， interleukin-13 （IL-13） and transforming growth factor-β1 （TGF-β1）. Compared with IL-4-induced group， 10-80 mg·L-1 XJD dose-dependently decreased CD206+ cell population （P<0.01） and inhibited the mRNA expression of Arg-1， IL-10， IL-13 and TGF-β1 （P<0.01）. Western blot showed that XJD significantly downregulated the activation of PI3K/Akt pathway as compared to LPS- and IL-4-induced groups （P<0.05， P<0.01）. ConclusionXJD significantly inhibited the macrophage polarization in the LPS- and IL-4-induced RAW264.7 cells by targeting PI3K/Akt pathway.

ABSTRACT
To investigate the toxicity and related mechanism of miltirone to human acute myeloid leukemia THP-1 cells. To be specific, the active components and targets of miltirone were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the target proteins were converted into standard gene names with UniProt. Acute leukemia-rela-ted target genes were screened from GeneCards and DisGeNET. Venn diagram was constructed with Venny 2.1 to yield the common targets of the disease and the drug. The protein-protein interaction(PPI) network was constructed by STRING and Cytoscape 3.8.2. THP-1 cells in the logarithmic growth phase were treated with dimethyl sulfoxide(DMSO), and 2.5, 5, 10, 15, and 20 μmol·L~(-1) miltirone for 24 h, respectively. The proliferation rate of cells was analyzed by carboxyfluorescein diacetate succinimidyl ester(CFSE), apoptosis rate by flow cytometry with Annexin V-PE/7 AAD staining, and cell morphology by acridine orange staining. Real-time quantitative PCR(qPCR) was employed to detect the mRNA levels of nuclear receptor coactivator 2(NCOA2), poly(ADP-ribose) polymerase-1(PARP1), B-cell lymphoma-2(Bcl-2)-associated X protein(Bax), Bcl-2, and cysteine aspartyl protease-3(caspase-3). The effect of miltirone on apoptosis was detected in presence of caspase inhibitor Z-VAD-FMK. A total of 26 targets of miltirone, 1 046 genes related to acute leukemia, and 6 common targets of the two were screened out. Flow cytometry result showed miltirone at 10 μmol·L~(-1) can inhibit proliferation and promote apoptosis of THP-1 cells. The typical manifestations of apoptosis, such as cell shrinkage, nuclear rupture, and chromatin agglomerate were displayed by acridine orange staining. The decreased mRNA levels of NCOA2 and PARP1 and increased Bax/Bcl-2 ratio and the activity of pro-apoptotic protein caspase-3 were observed. Z-VAD-FMK can attenuate the apoptosis-inducing effect of miltirone. This study indicates that miltirone can inhibit the proliferation and promote the apoptosis of THP-1 cells, by down-regulating NCOA2 and PARP1, raising Bax/Bcl-2 ratio, and activating caspase-3.

Aconiti Kusnezoffii Radix Cocta is one of the most commonly used medicinal materials in Mongolian medicine. Due to the strong toxicity of Aconiti Kusnezoffii Radix Cocta, Mongolian medicine often uses Chebulae Fructus, Glycyrrhizae Radix et Rhizoma to reduce the toxicity, so as to ensure the curative effect of Aconiti Kusnezoffii Radix Cocta while ensuring its clinical curative effect, but the mechanism is not clear. The aim of this study was to investigate the effects of Chebulae Fructus, Glycyrrhizae Radix et Rhizoma and Aconiti Kusnezoffii Radix Cocta on the mRNA transcription and protein translation of cytochrome P450(CYP450) in the liver of normal rats. Male SD rats were randomly divided into negative control(NC) group, phenobarbital(PB) group(0.08 g·kg~(-1)·d~(-1)), Chebulae Fructus group(0.254 2 g·kg~(-1)·d~(-1)), Glycyrrhizae Radix et Rhizoma group(0.254 2 g·kg~(-1)·d~(-1)), Aconiti Kusnezoffii Radix Cocta group(0.254 2 g·kg~(-1)·d~(-1))and compatibility group(0.254 2 g·kg~(-1)·d~(-1),taking Aconiti Kusnezoffii Radix Cocta as the standard). After continuous administration for 8 days, the activities of total bile acid(TBA), alkaline phosphatase(ALP), amino-transferase(ALT) and aspartate aminotransferase(AST)in serum were detected, the pathological changes of liver tissue were observed, and the mRNA and protein expression levels of CYP1 A2, CYP2 C11 and CYP3 A1 were observed. Compared with the NC group, the serum ALP, ALT and AST activities in the Aconiti Kusnezoffii Radix Cocta group were significantly increased, and the ALP, ALT and AST activities were decreased after compatibility. At the same time, compatibility could reduce the liver injury caused by Aconiti Kusnezoffii Radix Cocta. The results showed that Aconiti Kusnezoffii Radix Cocta could inhibit the expression of CYP1 A2, CYP2 C11 and CYP3 A1, and could up-regulate the expression of CYP1 A2, CYP2 C11 and CYP3 A1 when combined with Chebulae Fructus and Glycyrrhizae Radix et Rhizoma. The level of translation was consistent with that of transcription. The compatibility of Chebulae Fructus and Glycyrrhizae Radix et Rhizoma with Aconiti Kusnezoffii Radix Cocta could up-regulate the expression of CYP450 enzyme, reduce the accumulation time of aconitine in vivo, and play a role in reducing toxicity, and this effect may start from gene transcription.

At weeks 0, 4, 8 and 12, the psoriasis area and severity index (PASI) was recorded, and adverse drug reactions were observed.Results:All 7 patients were treated for at least 12 weeks. After 4-week treatment, 4 patients achieved PASI50; after 12-week treatment, 5 achieved PASI75, and 2 achieved PASI90. No serious adverse drug reactions occurred. One patient developed fever during the treatment, but the body temperature returned to normal after management; another 1 developed cough and expectoration, and the symptoms were relieved after oral administration of a Chinese herbal preparation named pharyngitis mixture.Conclusion:Secukinumab is effective in the treatment of erythrodermic psoriasis, with fewer adverse reactions, which provides a new option for the treatment of erythrodermic psoriasis.
ABSTRACT
Objective:To explore the relationship of cardiovascular health behavior and factors with development of bone mass loss and postmenopausal osteoporosis in Suxichang area of Jiangsu province.Methods:In the across sectional study, a total of 2 423 postmenopausal women receiving health check-up from March 2019 to June 2020 in our hospital were enrolled.The seven variable factors included cardiovascular health behavior(body mass index, exercise, healthy diet and smoking state)and cardiovascular health-influencing factors(blood pressure, fasting blood glucose and total cholesterol). The information of the seven factors and bone mineral density were recorded.The seven factors were classified as ideal, average and poor, according to the level of bone mineral density.All individuals were divided into three groups: normal bone mass(n=1 305), osteopenia(n=290)and osteoporosis(n=828).Results:There were statistically significant differences in age, fasting blood glucose, systolic blood pressure, diastolic blood pressure, total cholesterol and exercise between osteoporosis and normal bone mass group( P<0.05). As the number of ideal cardiovascular health behaviors and factors increased, the proportion of bone mass loss and osteoporosis gradually decreased( P<0.05). Multiple logistic regression analysis showed that ageing, increased total cholesterol and fasting blood glucose levels were the independent risk factors of osteoporosis.The exercise and normal body mass index were the protective factors for osteoporosis.For each 1 unit increment in age, total cholesterol, body mass index and fasting blood glucose, the OR values for bone mineral density decrement by 1 grade were 1.17, 1.25, 0.92 and 1.23, respectively(all P<0.05). The OR value for bone mineral density decrement by 1 grade was 0.58( P<0.05)when exercise decreased by 1 grade. Conclusions:Postmenopausal women should positively control the levels of total cholesterol and fasting blood glucose, maintain reasonable body weight and conduct regular exercise, which are conductive to the prevention and treatment of postmenopausal osteoporosis.

Objective:To investigate the efficacy and adverse reactions of immunotherapy in elderly patients(≥65 years old)with lung squamous cell carcinoma(LUSC)in Chinese population of real world.Methods:A total of 113 elderly LUSC patients(age ≥65 years old)underwent pathological diagnosis were involved from January 2018 to January 2022.To compare the efficacy of mono-immunotherapy or combined with chemotherapy to chemotherapy in first-line and second-line treatment.44 patients received surgical or minimally invasive treatment, and 69 patients received first-line medical treatment, including 27 patients in chemotherapy group, 24 patients in combined chemotherapy group, and 11 patients in single drug immunization group.7 cases in targeted therapy group.Twenty-eight patients received second-line medical treatment, including 8 patients in chemotherapy group, 11 patients in combined immunochemotherapy(combined group), 4 patients in single drug immunotherapy group, and 5 patients in targeted therapy group.The therapeutic effects and adverse reactions were compared between the first-line and second-line treatments.The expression of programmed death-ligand 1(PD-L1)and tumor mutational burden(TMB)were evaluated.Response evaluation criteria in solid tumors(RECIST)version 1.1 was used to evaluate the efficacy, and common terminology criteria for adverse events(CTCAE)version 4.03 was used to evaluate immune-related adverse.Kaplan-meier and log-rank test was performed.Cox regression was used in prognostic analysis.Results:The total effective rate in the first-line combination group was 73.7%(14/19), higher than that in the chemotherapy group(24.0%, 6/25), and the difference was statistically significant( χ2=10.748, P<0.01). Median progression-free survival(mPFS)was longer in the first-line combination group, the immunization group, and the chemotherapy group, and the median overall survival(mOS)was longer in the combination group, but the differences were not statistically significant(all P<0.05); mOS in the second-line combined group were longer than those in the chemotherapy group, both P<0.01). Elderly patients with lung squamous cell carcinoma had high PD-L1 positive rate(≥1%)and high TMB expression rate(≥9 mut/Mb), 81.6%(31/38)and 57.4%(31/54), respectively.mPFS in the PD-L1 positive group(≥1%)was better than that in the PD-L1 negative group(5.10 months vs.0.93 months, P<0.05). Among PD-L1 positive patients, mPFS in the second-line combination group was better than that in the chemotherapy group(7.33 months vs.2.77 months, P<0.05). mPFS and mOS time were not related to TMB expression.The overall incidence of immune-related adverse reactions was 62.0%(31/50), and 26.0%(13/50)with grade 3 or above.The most common grade 3 adverse events were rash, immune-associated pneumonia, and fatigue. Conclusions:Immunology combined with chemotherapy increased objective response rate, mPFS and mOS of elderly patients with LUSC group in first-line therapy compared with chemotherapy.In second-line treatment, the mOS was significantly prolonged in both combination therapy and mono-immunotherapy, and the combination therapy exhibited no benefit in OS compared with monotherapy.The adverse effects of immunology in elderly patients with LUSC were controllable.
ABSTRACT
Objective:To study the clinical features of intrahepatic biliary cystadenoma (BCA), with the aim to improve its treatment results.Methods:The clinical data and follow-up results of 86 patients with BCA treated at our department from March 2010 to January 2021 were retrospectively analyzed. Of 86 patients, there were 15 males and 71 females, with age of (48.4±13.1) years old. According to the surgical procedures carried out, 44 patients were divided into the minimally invasive group and 42 into the open group. Clinical data including imaging data, blood biochemistry, and tumor markers were collected. The follow-up data of these patients was collected in outpatient clinics or by telephone review.Results:Of 86 patients, 19(22.1%) patients had a monocystic lesion while 67(77.9%) patients had a multicystic lesion, 64 patients (74.4%) had intracapsular segregation, and 12(14.0%) patients had solid structures. Eighty-six patients with BCA were misdiagnosed as hepatic cysts in 9 patients (10.4%), hepatic echinococcosis in 2 patients (2.3%), biliary hamartoma in 1 patient (1.2%), and hepatic hemangioma in 1 patient (1.2%) before surgery. The tumor size [(6.5±3.2) vs. (9.0±4.0) cm], operative time [115(88, 185) vs. 195(160, 254) min], intraoperative blood loss [50(20, 162) vs. 300(200, 600) ml], and postoperative hospital stay [4(3, 6) vs. 8(7, 10) d] were significantly lower in the minimally invasive group than the open group. The differences were statistically significant ( P<0.05). In the 73 patients with complete follow-up, (median follow-up 63.5 months), 4 patients had developed tumor recurrence. Conclusion:Intrahepatic bile duct cystadenoma lacks specific clinical manifestations, and has a high rate of misdiagnosis and mistreatment. Early radical hepatectomy improved clinical outcomes.
ABSTRACT
Objective:To explore the risk of hip fracture, changes of composite indices of femoral neck strength and its influential factors in non-low-weight postmenopausal women with type 2 diabetes mellitus(T2DM).Methods:A total of 626 non-low-weight postmenopausal women were selected and divided into type 2 diabetes group, pre-diabetic group, and non-diabetic group according to the diagnostic criteria of the American Diabetes Association in 2010. Each participant completed the questionnaire, physical examination, laboratory examination, and Dual-energy X-ray absorptiometry(DXA) examination.Results:Hip fracture rate in T2DM group was significantly higher than that in non-diabetic group(3.4% vs 0.7%, P<0.05), while no significant difference was observed between pre-diabetic group and non-diabetic group(1.1% vs 0.7%, P>0.05). Bone mineral density(BMD) of lumbar spine 1-4, femoral neck, and total hip was comparable between T2DM group and non-diabetic group or pre-diabetic group and non-diabetic group, respectively( P>0.05). The composite indices of femoral neck strength in T2DM group was significantly lower than that in non-diabetic group( P<0.05), but there was no significant difference between pre-diabetic group and non-diabetic group( P>0.05). Regression analysis showed that age and body mass index were the main influential factors of the femoral neck bone mineral density and the composite indices of femoral neck strength( P<0.05). Conclusion:The composite indices of femoral neck strength could be used as one of the markers to evaluate the risk of hip fracture in type 2 diabetic patients.
ABSTRACT
Objective:The aim of this study was to explore the associations of muscle size and density with handgrip strength(HGS)and the Timed Up and Go(TUG)test.Methods:Totally 301 participants living in the Xinjiekou community near Beijing Jishuitan Hospital were recruited for CT imaging of the hip and a 1-cm slice of the mid-thigh.The cross-sectional area and density of the gluteus maximus and the mid-thigh muscles were estimated by the Osirix viewer based on CT images.HGS and TUG were also performed in these subjects.Logistic regression analysis was used to evaluate the correlations of muscle density and size with TUG and grip strength.Results:In women, after adjustment for age and BMI, the density of the gluteus maximus was negatively correlated with TUG( P trend=0.0366), while the size of the gluteus maximus and the mid-thigh muscles was not correlated with TUG.In men, the density or size of these muscles was not correlated with TUG.After adjustment for age and BMI, the density of the gluteus maximus was positively correlated with grip strength( P trend=0.0334)and the size of the mid-thigh muscles was also positively correlated with grip strength( P trend=0.0155)in men, but they were not correlated with grip strength in women. Conclusions:There were sex differences in the relationship between muscle size or density and grip strength or timed up and go.The density of the gluteus maximus is associated with muscle strength and physical performance while the size of the mid-thigh muscles is correlated with muscle strength.
