ObjectiveTo investigate the inhibitory effect of Biejia Decoction Pill on the proliferation， migration， and aerobic glycolysis of hepatocellular carcinoma （HCC） using cell experiments， as well as related mechanisms. MethodsHuman liver cancer cell line Huh7 was selected， and Sprague-Dawley rats were randomly divided into blank serum group， inhibitor group， and high-， middle-， and low-dose Biejia Decoction Pill groups. Rat serum containing the drug was prepared for the incubation of Huh7 cells. CCK8 assay and scratch assay were used to explore the effect of Biejia Decoction Pill on the proliferation and migration of HCC cells； glycolytic rate-limiting enzymes and metabolites were measured to explore the effect of Biejia Decoction Pill on aerobic glycolysis of liver cancer cells； RT-qPCR and Western blot were used to explore the effect of Biejia Decoction Pill on the mRNA expression， related proteins， and phosphorylation of the protein kinase B （AKT）/mammalian target of rapamycin （mTOR） signaling pathway. A one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test or the Dunnett’s T3 test were used for further comparison between two groups. ResultsCompared with the blank serum group， the Biejia Decoction Pill groups had significant reductions in OD value， migration rate during different periods of time， glycolytic rate-limiting enzymes （hexokinase， phosphofructokinase， pyruvate kinase）， and glycolytic metabolites （pyruvate， lactic acid， ATP） （all P<0.05）. RT-qPCR results showed that compared with the blank serum group， the high-， middle-， and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of mTOR， and the high- and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of AKT （all P<0.05）. Western blot results showed that compared with the blank serum group， the high-， middle-， and low-dose Biejia Decoction Pill groups had significant reductions in the expression levels of mTOR-related proteins and phosphorylated proteins， and the high- and middle-dose Biejia Decoction Pill groups had significant reductions in the expression levels of AKT-related proteins and phosphorylated proteins （all P<0.05）. ConclusionThis study preliminarily verifies that the serum containing Bijia Decoction Pill can inhibit the aerobic glycolysis of human hepatoma Huh7 cells， thereby inhibiting their proliferation and migration， possibly by inhibiting the expression of the proteins related to the AKT/mTOR signaling pathway.

Objective To generate a dense granule protein 3 (GRA3) gene-deficient mutant of the Toxoplasma gondii ME49 strain and to test the virulence of the mutant. Methods Gene-deficient parasites were generated with the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (CRISPR/Cas9) system. Guide RNA (gRNA) was designed using the E-CRISPR software, and mutated on the pSAG1::Cas9-U6::sgUPRT plasmid using the Q5 site-directed mutagenesis kit to generate the pSAG1::Cas9-U6::sgGRA3 plasmid. A GRA3 donor plasmid containing GRA3 gene upstream sequences, pyrimethamine resistant gene dihydrofolate reductase-thymidylate synthase (DHFR-TS) and GRA3 gene downstream sequence was generated, and GRA3 donor DNA was amplified using PCR assay. The pSAG1::Cas9-U6::sgGRA3 plasmid and GRA3 donor DNA were electroporated into tachyzoites of the wild-type T. gondii ME49 strain. Then, parasite suspensions were inoculated into human foreskin fibroblast (HFF) cells and screened with pyrimethamine to yield pyrimethamine-resistant parasites for monoclonal screening. The GRA3 gene deficient monoclonal strain (ME49Δgra3) of T. gondii was identified using PCR and Western blotting assays, and the expression of GRA3 protein was determined in the T. gondii ME49Δgra3 strain using Western blotting. Subsequently, 1 000 freshly lysed tachyzoites of T. gondii ME49 and ME49Δgra3 strains were transferred to 12-well plates seeded with HFF cells, and incubated at 37 °C containing 5% CO₂ for 7 days, and the number of plaques was counted by staining with crystal violet solutions. HFF cells infected with tachyzoites of T. gondii ME49 and ME49Δgra3 strains were stained using Giemsa solutions, and the numbers of cells containing 1, 2, 4, and > 4 T. gondii parasitophorous vacuoles were counted. In addition, the survival rates of C57BL/6 mice infected with T. gondii ME49 and ME49Δgra3 strains were compared 35 days post-infection. Results PCR assay revealed successful amplification of both the upstream and downstream homologous arm bands of the DHFR-TS gene in the T. gondii ME49Δgra3 strain, and no corresponding bands were amplified in the ME49 strain. The GRA3 band was amplified in the ME49 strain, and the DHFR-TS band, rather than GRA3 band, was amplified in the ME49Δgra3 strain. Western blotting determined absence of GRA3 protein expression in the ME49Δgra3 strain. Crystal violet staining showed that the T. gondii ME49 strain produced more plaques than the ME49Δgra3 strain [(352.67 ± 26.39) plaques vs. (235.00 ± 26.29) plaques; t = 5.472, P < 0.01], and Giemsa staining revealed that the proportion of T. gondii parasitophorous vacuoles containing at least four T. gondii tachyzoites was higher in HFF cells infected with the ME49 strain than in those infected with the T. gondii ME49Δgra3 strain [(75.67 ± 2.52)% vs. (59.67 ± 2.31)%; t = 8.113, P < 0.01], and the proportion of T. gondii parasitophorous vacuoles containing at least 1 or 2 T. gondii tachyzoites was higher in HFF cells infected with the T. gondii ME49 strain than in those infected with the T. gondii ME49Δgra3 strain [(24.33 ± 2.52)% vs. (40.33 ± 2.31)%; t = −8.113, P < 0.01]. In addition, mice infected with the T. gondii ME49 and ME49Δgra3 strains started to die 8 and 9 days post-infection, and the 35-day mortality rates of mice infected with T. gondii ME49 and ME49Δgra3 strains were 10.00% and 70.00% post-infection (χ² = 6.762, P < 0.01). Conclusions The T. gondii ME49Δgra3 strain has been successfully generated, and GRA3 protein may increase the virulence of the T. gondii ME49 strain.

BACKGROUND:High tibial osteotomy results in massive blood loss during the perioperative period.Tranexamic acid can effectively reduce perioperative blood loss.However,the method of tranexamic acid application has not been unified. OBJECTIVE:To investigate the effect and safety of different methods of tranexamic acid on perioperative blood loss in the high tibial osteotomy. METHODS:A total of 160 patients who underwent primary unilateral high tibial osteotomy in the Binzhou Medical University Hospital from January 2019 to December 2021,including 69 males and 91 females,were randomly divided into four groups(n=40 per group).Among them,40 patients were given an intravenous infusion of saline containing 2 g tranexamic acid 10 minutes before tourniquet release(venous group);40 patients were given an intravenous infusion of 1 g tranexamic acid and 1 g tranexamic acid was injected through a drainage tube after the closure of the incision(combined group);40 patients were given 2 g tranexamic acid infusion into drainage tube after the closure of the incision(perfusion group);an additional 40 patients were given an intravenous infusion of the same amount of normal saline(blank group).The general information was compared among the four groups of patients.The hemoglobin,hematocrit,intraoperative blood loss,drainage volume,blood transfusion rate,incision complication,and the incidence of deep vein thrombosis were recorded on days 1,3 and 5 after operation in the four groups.The total blood loss and hidden blood loss were calculated. RESULTS AND CONCLUSION:(1)There was no statistically significant difference in general information among the four groups.(2)No significant difference was found in intraoperative blood loss among the four groups.(3)The maximum decreased values of hemoglobin and hematocrit on days 1,3 and 5 after operation,drainage volume,total blood loss and hidden blood loss were all ranked as the combined group

Objective:To study the composition and influencing factors of hospitalization expenses of patients with sequelae of ce-rebral infarction caused by the dominant diseases of traditional Chinese medicine(TCM),so as to provide references for the fine management within the hospital and the medical insurance department to improve the payment policy suitable for the characteristics of TCM.Method:A total of 1 261 cases with ICD code 169.3 in the sample of tertiary traditional Chinese medicine hospitals from 2020 to 2022 were collected.Single factor analysis,correlation analysis,multiple linear stepwise regression and other methods were used to analyze the composition and main influencing factors of hospitalization expenses of patients with cerebral infarction sequelae.Re-sults:The average length of hospital stay of patients with sequelae of cerebral infarction was 16.71 days per time,the average hospi-talization cost was 24 148.83 yuan per time,and the proportion of TCM treatment cost per time was 54.43％.The results of stepwise regression showed that the length of stay,the condition of admission and the complication of pulmonary infection had a significant im-pact on the hospitalization expenses(P＜0.05),and the length of stay had the greatest impact.Conclusion:It is suggested that the hospital should optimize and improve the clinical pathway of TCM dominant diseases and establish an effective dynamic management mechanism,and the medical insurance department should improve the adjustment mechanism of the auxiliary list of TCM dominant diseases under the disease scoring payment.

At present, the major public health challenges caused by novel coronavirus infection have gradually subside. However, a large number of people are still suffering from long-novel coronavirus syndrome or post-novel coronavirus syndrome. The clinical manifestations of long coronavirus syndrome are related to multiple systems, such as respiratory, circulatory, nervous, digestive and musculoskeletal systems, with various long-term persistent symptoms after novel coronavirus infection. At the same time, the infection of the novel coronavirus is an important cause of frailty and sarcopenia in the elderly population. However, at present, the scholars have not paid enough attention to the skeletal muscle weakness caused by the novel coronavirus. Therefore, this paper focuses on the long-novel coronavirus syndrome and sarcopenia to explore the pathological mechanism of skeletal muscle attenuation caused by the SARS-CoV-2 mediated "cytokine storm", mitochondrial damage, hypoxia state and other links, so as to raise the attention of clinical and academic researchers and improve the clinical strategy of frailty and sarcopenia after novel coronavirus infection.

AIM: To understand the current status and differences in visual acuity of children of the same age from different regions of Xi'an, and to take an effective basis for the prevention of children's myopia.METHODS: Random stratified sampling was used to select the uncorrected distance visual acuity and computed dioptric data of 41 285 children aged 6-12 from 6 towns, 10 urban and rural areas and 112 country schools screened by Xi'an Central Hospital in December 2022.RESULTS: The myopia detection rate in different regions of Xi'an is 47.16% in towns, 38.59% in urban and rural areas, and 32.29% in the country, and the total myopia rate is 37.50%. The myopia rate of 6-12 years old in towns is higher than that in urban and rural areas, and that of urban and rural areas is higher than that of country; the myopia rate of girls is higher than that of boys; myopia rate increases with age; mild myopia: the myopia rate in towns is significantly higher than that of the urban and rural areas and the country; high myopia: the myopia rate in the country is significantly higher than that of the towns and the urban and rural areas. The total rate of deficient hyperopia reserves in different regions of Xi'an is 92.08% in towns, 93.67% in urban and rural areas, and 90.92% in the country, and the total rate of deficient hyperopia reserves is 92.09%. The rate of deficient hyperopia reserves at the age of 6-12 is higher in the urban and rural areas than in the towns, and higher in the towns than in the country; the total rate of deficient hyperopia reserve is higher in girls than in boys; it is the peak period of the development of hyperopia reserve rate before the age of 8.CONCLUSION: The total myopia rate and the total vision reserve deficiency rate of 6-12 years old in different regions of Xi'an are different, and 8-9 years old is the accelerated period of myopia development, and the peak of deficient hyperopia reserve is before the age of 8 years old. With the growth of age, the myopia rate shows a certain growth trend, and the rate of deficient hyperopia reserve shows a decreasing trend after reaching the peak. The total myopia rate and insufficient acuity reserve rate of girls are higher than those of boys.

Objective To investigate the effect of oral fish oil on wound healing and related indexes in patients with diabetic foot ulcer(DFU).Methods A randomized,double-blind,placebo-controlled design was used to recruit 68 patients with DFU aged 18-80 years old in the hospital,and the baseline clinical data of the patients were collected.The patients were randomly divided into experimental group(32 cases,fish oil soft capsule,3 g/d)and control group(33 cases,corn oil soft capsule,3 g/d)by random number generated by Ex-cel,and the intervention lasted for 12 weeks.The primary endpoints included the proportion of complete wound healing and healing area≥50%.The secondary endpoints included wound area,healing time,inflamma-tion index,glucose metabolism index,nutrition related index and wound reinfection.Additionally,the influen-cing factors of wound healing were analyzed.Results After intervention,the proportion of complete wound healing and healing area≥50%in the experimental group was significantly higher than that in the control group(P=0.007,0.039).In the subjects with complete wound healing,the mean healing time in the experi-mental group was shorter than that in the control group,but the difference was not statistically significant(P=0.132).The reduction area of wound area in the experimental group was significantly larger than that in the control group(P=0.045).The decrease of interleukin(IL)-6 and IL-8 in the experimental group was significantly higher than that in the control group(P<0.05).There was no significant difference in the reduc-tion of C-reactive protein(CRP),tumor necrosis factor-α(TNF-α),neutrophil-to-lymphocyte ratio(NLR),glycated hemoglobin A1c(HbA1c)and platelet-to-lymphocyte ratio(PLR)between the two groups(P>0.05).The improvement of prealbumin(PA)in the experimental group was higher than that in the control group,but the difference was not statistically significant(P>0.05).Multivariate logistic regression analysis showed that oral fish oil intervention(OR=6.771,95%CI:1.787-25.652),HbA1c(OR=4.149,95%CI:1.026-16.770)and ulcer type(OR=4.319,95%CI:1.026-18.173)were the influencing factors of wound healing(P<0.05).Conclusion Oral fish oil promotes wound healing in patients with DFU,which may be re-lated to improving the level of chronic inflammation in the body.
