Objective To observe the clinical efficacy of Tongfengke Granules combined with external treatment of TCM in acute gouty arthritis(AGA)with damp-heat accumulation type.Methods A total of 96 patients with AGA were divided into the experimental group and the control group according to random number table method,with 48 patients in each group.The control group received meloxicam treatment.On this basis,the experimental group was treated with Tongfengke Granules(1 bag at a time,three times a day,orally)combined with external therapy of TCM(once a day),and mobile continuing care.The treatment for both groups lasted for 2 weeks.The clinical efficacy of both groups was observed.Before and after the treatment,pain visual analogue scale(VAS),TCM syndrome scores,major symptom scores,and levels of serum uric acid(UA),interleukin-6(IL-6),erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),platelet/lymphocyte ratio(PLR),as well as engagement in self-care ability scale(ESCA),general self-efficacy scale(GSES),negative psychological condition[self-rating depression scale(SDS),self-rating anxiety scale(SAS)]were measured.The adverse reactions in both groups were monitored.Results Totally 45 and 47 patients in the experimental group and control group were finally included respectively in the analysis.The total effective rate of the experimental group was 75.6%(34/45),while that of the control group was 63.8%(30/47),with statistical significance(P<0.05).Compared with before treatment,the VAS score and TCM syndrome score in the experimental group decreased significantly(P<0.05);after treatment,the VAS score and TCM syndrome score of the experimental group were lower than those of the control group(P<0.05).Compared with before treatment,the joint pain,joint tenderness,joint swelling,and joint mobility limitation scores in both groups were significantly decreased after treatment(P<0.05,P<0.01);after treatment,the scores of joint pain,joint tenderness,and joint swelling in the experimental group were lower than those in the control group(P<0.01).Compared with before treatment,the levels of UA,ESR,CRP and PLR in both groups decreased significantly after treatment(P<0.01);after treatment,the levels of UA,ESR,CRP and PLR in the experimental group were lower than those in the control group(P<0.05,P<0.01).Compared with before treatment,the experimental group showed significant improvement in ESCA,GSES and SAS after treatment(P<0.05,P<0.01),while the control group showed significant improvement in ESCA(P<0.01);after treatment,the ESCA and GSES of the experimental group were better than those of the control group(P<0.05,P<0.01).There was no statistical significance in safety indicators and incidence of adverse reactions between the two groups(P>0.05).Conclusion Tongfengke Granules combined with external treatment of TCM can significantly improve the clinical efficacy of AGA,reduces UA levels,significantly improves inflammatory response,and has anti-inflammatory,anti-inflammatory,and analgesic effects.

Objective: To study the expression and effect of small nuclear ribonucleoprotein-associated protein B (SNRPB) on proliferation and metastasis of liver cancer tissues and cells. Methods: The bioinformatics database starBase v3.0 and GEPIA were used to analyze the expression of SNRPB in liver cancer tissue and normal liver tissue, as well as the survival and prognosis of liver cancer patients. The expression of SNRPB mRNA and protein in liver cancer cell lines were analyzed by qRT-PCR and Western blot. RNA interference technique (siRNA) was used to determine SNRPB protein expression down-regulation. The proliferation effect on hepatocellular carcinoma cells was observed by MTT assay. Transwell invasion and migration assay was used to detect the changes in the metastatic ability of liver cancer cells after SNRPB down-regulation. Western blot was used to detect the changes of epithelial mesenchymal transition (EMT) markers in liver cancer cells after down-regulation of SNRPB expression. Data were compared between two groups and multiple groups using t-test and analysis of variance. Results: The expression of SNRPB was significantly higher in liver cancer tissue than normal liver tissue, and its expression level was correlated with the prognosis of liver cancer patients. Compared with the immortalized hepatocyte LO(2), the expression of SNRPB was significantly increased in the liver cancer cells (P < 0.01). siRNA-SNRPB had significantly inhibited the expression of SNRPB mRNA and protein in liver cancer cells. MTT results showed that the absorbance value was lower in SNRPB knockdown group than negative control group, and the difference at 96 h after transfection was most significant (P < 0.01). Transwell assay results showed that compared with the negative control group, the SNRPB knockdown group (MHCC-97H: 121.27 ± 8.12 vs. 46.38 ± 7.54; Huh7: 126.50 ± 6.98 vs. 41.10 ± 8.01) invasion and migration (MHCC-97H: 125.20 ± 4.77 vs. 43.18 ± 7.32; Huh7: 132.22 ± 8.21 vs. 38.00 ± 6.78) ability was significantly reduced (P < 0.01) in liver cancer cells. Western blot showed that the expression level of epithelial phenotype marker E-cadherin was decreased after down-regulation of SNRPB, while the expression levels of mesenchymal phenotype markers N-cadherin and vimentin was increased, suggesting that down-regulation of SNRPB inhibited EMT in liver cancer cells. Conclusion: SNRPB expression is significantly increased in liver cancer tissues and cells, and it is involved in regulating the proliferation, metastasis and EMT of liver cancer cells.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

OBJECTIVE: To study the application value of whole exome sequencing (WES) in critically ill neonates with inherited diseases. METHODS: A total of 66 critically ill neonates with suspected inherited diseases or unclear clinical diagnosis who were admitted to the neonatal intensive care unit were enrolled as subjects. The clinical data of the neonates were collected, and venous blood samples were collected from the neonates and their parents for WES. The clinical manifestations of the neonates were observed to search for related pathogenic gene mutations. RESULTS: Among the 66 critically ill neonates with suspected inherited diseases or unclear clinical diagnosis (34 boys and 32 girls), 14 (21%) were found to have gene mutations by WES. One neonate had no gene mutation detected by WES but was highly suspected of pigment incontinence based on clinical manifestations, and multiplex ligation-dependent probe amplification detected a heterozygous deletion mutation in exons 4-10 of the IKBKG gene. Among the 15 neonates with gene mutations, 10 (67%) had pathogenic gene mutation, 1 (7%) was suspected of pathogenic gene mutation, and 4 (27%) had gene mutations with unknown significance. Among the 15 neonates, 13 underwent chromosome examination, and only 1 neonate was found to have chromosome abnormality. CONCLUSIONS Chromosome examination cannot be used as a diagnostic method for inherited diseases, and WES detection technology is an important tool to find inherited diseases in critically ill neonates with suspected inherited diseases or unclear clinical diagnosis; however WES technology has some limitation and it is thus necessary to combine with other sequencing methods to achieve an early diagnosis.

OBJECTIVETo observe the effect of Schistosoma japonicum cysteine protease inhibitor (rSjCystatin) for treatment of lipopolysaccharide (LPS)-induced sepsis in mice.

METHODSAfter a week of adaptive feeding, 54 BALB/c mice were randomly divided into normal control group (group A), sepsis group (group B), and rSjCystatin intervention group (group C). The mice in group A received an intraperitoneal injection of PBS (100 µL), and those in groups B and C were injected with PBS (100 µL) containing LPS (10 mg/kg); the mice in group C were also intraperitoneally injected with 25 µg sjCystatin in 100 µL PBS 30 min after LPS injection. From each group, 10 mice were randomly selected 24 h after PBS or LPS injection for detecting serum levels of TNF-α, IL-6, and IL-10 using ELISA and the levels of ALT, AST, BUN, and Cr using automatic biochemical analyzer; the pathological changes in the liver, lung and kidney were observed with HE staining. The remaining 8 mice in each group were used for observing the changes in the general condition and the 72-h survival.

RESULTSThe 72-h survival rates of the mice was 100% in group A, 0 in group B, and 36% in group C, showing a significant difference among the 3 groups (P<0.05). Compared with those in group A, the mice in group B exhibited obvious liver, lung, and renal pathologies with increased levels of ALT, AST, BUN, Cr, IL-6, and TNF-α (P<0.05). Treatment with sjCystatin significantly lessened LPS-induced organ pathologies, lowered the levels of liver and renal functional indexes and the pro-inflammatory cytokines, and increased the serum level of IL-10 in the mice (P<0.05).

CONCLUSIONSjCystatin can produce a significant therapeutic effect on sepsis induced by LPS in mice.

Traditional Chinese Medicine massage is a kind of physiotherapy which affects on specific parts of the body surface by means of training to regulate the function of the body to achieve the therapeutic effect. In this work,under positive detection model, the chemical fingerprint of exhaled breath from volunteers before and after receiving Traditional Chinese Medicine massage within m/z 50-1000 were detected by extractive electrospray ionization-mass spectrometry (EESI-MS). And through high resolution mass spectrometry analysis, the metabolites such as epinephrine (m/z 184. 0889), 3-(3-hydroxyphenyl) propionic acid (m/z 167.0615) and L-tryptophan (m/z 205. 0933) were successfully identified. Besides, chemical fingerprints of volunteers before and after receiving Traditional Chinese Medicine massage under different health condition were clearly differentiated via partial least squares discrimination analysis (PLS-DA). The results showed that Traditional Chinese Medicine massage could significantly change the metabolic process of volunteers. Moreover, it further indicated that the established method could provide a real time fashion to follow metabolic changes caused by Traditional Chinese Medicine massage.

Objective To investigate the effect of cysteine protease inhibitor derived from S chistosoma japonicum(SjCys-tatin)on dextran sodium sulfate(DSS)-induced acute ulcerative colitis in mice.Methods Eighteen C57BL/6 mice were ran-domly divided into three groups:a control group treated with PBS(Group A),a DSS-induced-colitis group treated with PBS(Group B),and a DSS-induced-colitis group treated with SjCystatin(Group C).Colitis was induced in mice by giving 3％DSS orally for 7 days.During this period,the mice were daily injected with 10&mu;g of SjCystatin or PBS only as a control intraperitone-ally.The mice were monitored daily for their clinical manifestations and given scores based on disease activity index(DAI).The severity of colonic inflammation was monitored by the macroscopic score and pathological change.The cytokine profile including TNF-α,IL-4,IL-6 and IL-10 in the supernatants of colon homogenate was detected by ELISA.Results Compared with Group A(0.50 ± 0.28),the DAI score increased significantly in Group B(9.30 ± 1.30)(F=86.86,P<0.01),with remarkable path-ological damages seen in colon tissues.and the levels of TNF-α and IL-6 were(321.33±67.01)and(403.58 ±180.51)pg/mL.The DAI score significantly reduced in Group C(6.67±1.57)as compared to Group B(F=86.86,P<0.01),with improve-ments in the macroscopic and microscopic pathology in mouse colon specimens.As compared to Group B,the levels of TNF-α [(188.14 ± 40.14)pg/mL] and IL-6 [(209.71 ± 48.47)pg/mL] significantly decreased(F=17.46 and 9.89,both P<0.01).Con-clusion SjCystatin has a significantly inhibitory effect for alleviating DSS-induced acute ulcerative colitis in C57BL/6 mice.

How to test the treatments of Chinese medicine (CM) and make them more widely accepted by practitioners of Western medicine and the international healthcare community is a major concern for practitioners and researchers of CM. For centuries, various approaches have been used to identify and measure the efficacy and safety of CM. However, the high-quality evidence related to CM that produced in China is still rare. Over the recent years, evidence-based medicine (EBM) has been increasingly applied to CM, strengthening its theoretical basis. This paper reviews the past and present state of CM, analyzes the status quo, challenges and opportunities of basic research, clinical trials, systematic reviews, clinical practice guidelines and clinical pathways and evidence-based education developed or conducted in China, pointing out how EBM can help to make CM more widely used and recognized worldwide.

Background:The Food and Drug Administration recently announced that the use of morcellation may cause fibroids or pelvic dissemination and metastasis of uterine sarcoma;therefore,the use of morcellation is limited in the USA.A large sample study is necessary to assess the proportion of uterine malignant tumors found in patients with laparoscopic myomectomy.Methods:A national multicenter study was performed in China.From 2002 to 2014,33,723 cases were retrospectively selected.We calculated the prevalence and recorded the clinical characteristics of the patients with malignancy after morcellation application.A total of 62 cases were finally pathologically confirmed as malignant postoperatively.Additionally,the medical records of the 62 patients were analyzed in details.Results:The proportion of postoperative malignancy after morcellation application was 0.18％ (62/33,723) for patients who underwent laparoscopic myomectomy.Nearly 62.9％ (39/62) of patients had demonstrated blood flow signals in the uterine fibroids before surgery.And,23 (37.1％) patients showed rapid growth at the final preoperative ultrasound.With respect to the pathological types,38 (61.3％) patients had detectable endometrial stromal sarcoma,13 (21.0％) had detectable uterine leiomyosarcoma,only 3 (3.2％) had detectable carcinosarcoma,and 5 (8.1％) patients with leiomyoma had an undetermined malignant potential.Conclusions:The proportion of malignancy is low after using morcellation in patients who undergo laparoscopic myomectomy.Patients with fast-growing uterine fibroids and abnormal ultrasonic tumor blood flow should be considered for malignant potential,and morcellation should be avoided.

Biological sample pretreatment is an important step in biological sample analysis. Due to the diversity of biological matrices, the analysis of target substances in these samples presents significant challenges to sample processing. To meet these emerging demands on biopharmaceutical analysis, this paper summarizes several new techniques of on-line biological sample processing: solid phase extraction, solid phase micro-extraction, column switching, limited intake filler, molecularly imprinted solid phase extraction, tubular column, and micro-dialysis. We describe new developments, principles, and characteristics of these techniques, and the application of liquid chromatography-mass spectrometry (LC-MS) in biopharmaceutical analysis with these new techniques in on-line biological sample processing.
