Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

The core of theory of visceral manifestation of spleen is about'spleen in charge of transportation and transformation,spleen qi dispersing the essence'.Middle-jiao spleen-earth has the functions of digesting food and transporting food essence,and maintaining the homeostasis of glucose and lipid metabolism in the body.'Spleen in charge of transportation and transformation,spleen qi dispersing the essence'functions like the glucose and lipid metabolism at physiological state.The deficiency of spleen results in the dysfunction of food in-take and digestion and the susceptibility to external pathogens;qi deficiency and blood stasis lead to the interior damp-heat,and the long-term accumulation of damp-heat develops into stasis and then turns into toxins,which eventually induces inflammation-to-tumor transition.The pathogenesis of'spleen deficiency being the root cause and stasis blended with toxins'is correlated with the pathological changes of inflammation-to-tumor transition.The therapy of strengthening the spleen,dispersing essence and removing turbidity is effective on improving the disorder of glucose and lipid metabolism,and the therapy of strengthening the spleen,resolving stasis and removing toxin is effective on restraining the process of inflammation-to-tumor transition in the stomach.It has become a new direction in the field of spleen-stomach research to expound the scientific connotation of the essence of spleen function of'spleen in charge of transportation and transformation,spleen qi dispersing the essence'from the perspective of glucose and lipid metabolism,to focus on the inflammation-to-tumor transition process of major diseases of digestive system,to explore the evolution of the traditional Chinese medicine syndromes of inflammatory diseases and precancerous lesions of the digestive tract,and to reveal the pharmacological mechanism of treatment from the perspective of spleen,which will enrich the scientific connotation of theory of visceral manifestation of spleen and promote the modernization and internationalization of traditional Chinese medicine.

This study aims to investigate the effect of modified Danggui Shaoyao Powder on the suppressor of cytokine signaling 3(SOCS3)/Toll-like receptor 4(TLR4) signaling pathway in gastric tissue of rats with chronic atrophic gastritis(CAG).Sixty SPF-grade SD rats were randomly assigned into the normal group, model group, Moluo Pills group, and high-, medium-, and low-dose groups of modified Danggui Shaoyao Powder.The rats in other groups except the normal group were treated with N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) to establish the CAG model.After 12 weeks of modeling, the rats in each group were administrated with corresponding drugs by gavage for 8 weeks.After the last administration, the histopathological changes of rat gastric mucosa were observed via hematoxylin-eosin(HE) staining.The serum levels of IL-6, TNF-α, and CRP were determined by enzyme-linked immunosorbent assay(ELISA).The mRNA levels of SOCS3 and TLR4 were determined by real-time PCR.The protein levels of SOCS3, TLR4, JAK2, p-JAK2, STAT3, and p-STAT3 in rat gastric tissue were measured by Western blot.Immunohistochemical method was employed to determine the protein levels of NF-κB, MyD88, NLRP3, Bcl-2, Bax, and Bad in rat gastric tissue.The results showed that modified Danggui Shaoyao Powder alleviated gastric mucosal atrophy of rats, significantly lowered the levels of IL-6, TNF-α, and CRP in rat serum, up-regulated the mRNA level of SOCS3, and down-regulated the mRNA level of TLR4 in rat gastric tissue.Furthermore, modified Danggui Shaoyao Powder up-regulated the protein level of SOCS3, down-regulated the protein levels of TLR4, p-JAK2, p-STAT3, NF-κB, MyD88, NLRP3, Bax, and Bad, and promoted the expression of Bcl-2 protein.Therefore, modified Danggui Shaoyao Powder may mitigate the gastric mucosal atrophy of rats by regulating the SOCS3/TLR4 signaling pathway.

Bivalves are species-rich mollusks with prominent protective roles in coastal ecosystems.Across these ancient lineages,colony-founding larvae anchor themselves either by byssus produc-tion or by cemented attachment.The latter mode of sessile life is strongly molded by left-right shell asymmetry during larval development of Ostreoida oysters such as Crassostrea hongkongensis.Here,we sequenced the genome of C.hongkongensis in high resolution and compared it to reference bivalve genomes to unveil genomic determinants driving cemented attachment and shell asymmetry.Importantly,loss of the homeobox gene Antennapedia(Antp)and broad expansion of lineage-specific extracellular gene families are implicated in a shift from byssal to cemented attachment in bivalves.Comparative transcriptomic analysis shows a conspicuous divergence between left-right asymmetrical C.hongkongensis and symmetrical Pinctada fucata in their expression profiles.Especially,a couple of orthologous transcription factor genes and lineage-specific shell-related gene families including that encoding tyrosinases are elevated,and may cooperatively govern asymmet-rical shell formation in Ostreoida oysters.

OBJECTIVE: To investigate the value of serum galactose-deficient IgA1 in the diagnosis of IgA nephropathy and explore its relationship with the decline of renal function and pathological grade of renal biospy samples of the patients. METHODS: The serum samples were collected from, Shengjing Hospital of China Medical Unerversity from January 2016 to December 2017,which included 40 IgA nephropathy patients(group A), 20 other primary glomerulonephritis patients(group B) and 20 healthy persons(group C).Serum levels of GD-IgA1 were detected in all the samples.The 24-hour urinary protein and serum creatinine were measured in group A and B,the eGFR calculated. Recorded the pathological grade of renal biospy samples and Lee's classification. Study the value of serum Gd-IgA1 level in diagnosing IgA nephropathy by drawing ROC curve and calculating the area under the curve. RESULTS: The serum levels of GdIgA1 in IgA nephropathy patients were significantly higher than those in other types of primary glomerular diseases and healthy controls.The area under ROC curve was 0.886.When serum Gd-IgA1 level is higher than 662.5 U/ml, it suggested that people were more likely to have a IgA nephropathy.The level of serum Gd-IgA1 was related to the decline of renal function and pathological grade of renal biospy samples in patients with IgA nephropathy. CONCLUSION: Serum Gd-IgA1 levels may be helpful in the diagnosis of IgA nephropathy in patients who can not undergo renal pathological examination.

OBJECTIVETo compare the efficacy difference between acupotomology and operation in the treatment of lumbar disc herniation (LDH).

METHODSOne hundred and eighty-four cases were randomized into an acupotomology group (109 cases) and an operation group (75 cases). In acupotomology group, acupotomology was applied to relevant local soft tissues in LDH and the reactive points in the distribution of superior gluteal nerves, at the outlet of sciatic nerve and in the nerve innervate area of the lower extremities separately. In operation group, the small-windowed discectomy through small incision was adopted. The clinical efficacies were assessed between two groups.

RESULTSIn acupotomology group, the clinical cured rate was 82.6% (90/109) and the effective rate was 96.3% (105/109). In operation group, they were 86.7% (65/75) and 97.3% (73/75) respectively. There were no significant differences in statistics between two groups (both P > 0.05).

CONCLUSIONAcupotomology is definitely effective in the treatment of lumbar disc herniation and its efficacy is similar to that of operation.

OBJECTIVETo isolate and characterize the side population cells (SP cells) in the lung adenocarcinomas cell line A549.

METHODSThe protein expression of ABCG2 in human lung adenocarcinoma cell line A549 was detected by immunohistochemistry. SP and NSP cells in the cell line A549 were isolated by FACS, and their differentiation was analysed. ABCG2 expression in the two cell subsets was detected by RT-PCR. The cell growth curves, cell division indexes, cell cycles, plate clone formation tests, migration and invasion assays, chemotherapeutic susceptibility tests, tests of the intracellular drug levels, and the tumor cell implantation experiments on nude mice were applied to study the biological properties of the two cell subsets. The expression of ABCG2 in the transplanted tumor in nude mice was detected by immunohistochemistry and RT-PCR.

RESULTSThe positive rate of ABCG2 expression in the A549 cells by immunohistochemistry was 2.13%. SP and NSP cells were isolated by FACS. The SP cells could produce both SP and NSP cells, while NSP cells only produced NSP cells. SP cells expressed ABCG2, but NSP cells did not. The proliferation and migration abilities of the two cell subsets were similar, but the invasion and tumorigenic ability of SP cells was significantly higher than that of NSP cells. The susceptibilities to DDP and its intracellular levels of the two cell subsets were similar, but the susceptibilities to 5-FU, VP16, NVB and GEM and their intracellular levels of NSP cells were significantly higher than those of the SP cells.

CONCLUSIONSSP cells in the human lung adenocarcinomas cell line A549 is enriched with tumor stem cells. An effective way to get lung adenocarcinomas stem cells is to isolate SP cells by FACS.

OBJECTIVETo evaluate the effectiveness and safety of mosapride on treatment of functional dyspepsia.

METHODSRandomized controlled clinical trial was conducted and patients suffered from functional dyspepsia were included. 5 mg mosapride was given three times daily for 4 weeks in the treatment group. 10 mg domperidone was given three times daily for 4 weeks as control. Changes on symptom score, gastric empty or new occurring events were included as outcomes.

RESULTS231 patients suffered from functional dyspepsia were selected by inclusion and exclusion criteria from August 15 to Oct 22, 1999. Of these, 108 (46.8%) were males, versus 123 (53.2%) females and 118 (51.2%) in the treatment group and 113 (48.9%) as controls. 222 (96.1%) patients were followed up. Results showed that the total efficacy rates in early satiety and abdominal distension were 84.5% and 90.1% in mosapride after the 2 weeks of treatment. Mosapride seemed to be more effective in improving symptoms of belching and heartburn than that in controls (P < 0.05). In 4 weeks, the total efficacy in improving symptoms of abdominal distention and belching showed more effective in mosapride than that in controls (P < 0.05). Decrease of symptoms score was more in mosapride than that in controls (P < 0.05). Mosapride was less effective in controls in improving the gastric empty in terms of proportion (46.2% vs. 25.9%, P = 0.020) and range (46.2% vs. 24.0%, P = 0.003). Side effects would include diarrhea, constipation, headache, dizziness, insomnia, skin scare and the like. There was no significant difference between the two groups (9.6% in mosapride vs. 14.0% in controls).

CONCLUSIONMosapride was safe and effective in improving the symptoms and gastric empty of functional dyspepsia.
