Based on the viewpoint of "sweat pore-qi and liquid-kidney collaterals"， it is believed that children's nephrotic syndrome is caused by the core mechanism of sweat pore constraint and closure， qi and liquid imbalance， and kidney collaterals impairment， and it is proposed that the treatment principle is to nourish the sweat pore， regulate qi and fluid， and supplement the kidney and unblock the collaterals. In clinic， guided by sequential therapy and according to the different disease mechanism characteristics of the four stages， including early stage of the disease， hormone induction stage， hormone reduction stage， hormone maintenance stage， the staged dynamic identification and treatment was applied. For early stage of the disease with edema due to yang deficiency， modified Zhenwu Decoction （真武汤） was applied to warm yang and drain water； for hormone induction stage with yin deficiency resulting in effulgent fire， modified Zhibai Dihuang Pill （知柏地黄丸） plus Erzhi Pill （二至丸） was used to enrich yin and reduce fire； for hormone reduction stage with qi and yin deficiency， modified Shenqi Dihuang Decoction （参芪地黄汤） was used to boost qi and nourish yin； for hormone maintenance stage， modified Shenqi Pill （肾气丸） was used to supplement yin and yang. Meanwhile， the treatment also attaches importance to the combination of vine-based or worm medicinals to dredge collaterals， so as to providing ideas for clinical treatment.

Colorectal cancer （CRC） is a prevalent malignant tumor of the digestive tract， with a high incidence and high mortality. The majority of patients are diagnosed at the middle or advanced stage， which severely influences and threatens their physical health. Current treatment modalities such as surgery， radiotherapy， and chemotherapy often encounter challenges including metastasis， recurrence， and drug resistance. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway serves as a classical regulator that regulates physiological processes such as cell cycle， autophagy， apoptosis， and proliferation. Overexpression of this pathway is observed in various tumors. In the context of CRC， the activation of this pathway can facilitate the proliferation， invasion， and migration， inhibit the autophagy and apoptosis， promote the epithelial-mesenchymal transition of CRC cells， enhance angiogenesis within the tumor， and contribute to chemotherapy resistance and radiation resistance in CRC. Traditional Chinese medicine （TCM） treatment can exert an anti-CRC effect by inhibiting this pathway， thereby improving clinical efficacy and safety. This article retrieves relevant research literature published domestically and internationally regarding the regulation of the PI3K/Akt/mTOR signaling pathway by TCM in the treatment of CRC and conducts detailed classification and summary. The active components of TCM include glycosides， flavonoids， alkaloids， terpenoids， polyphenols， and naphthoquinones. The volatile oils and extracts of TCM include Angelicae Sinensis Radix volatile oil， Astragali Radix polysaccharides， Caryophylli Flos extract， Forsythiae Fructus extract， Curcumae Longae Rhizoma extract， and Celastrus orbiculatus extract. The compound formulas of TCM include Banxia Xiexin decoction， Jianpi Qingre Huoxue formula， and Chanling Plaster. Through summary and analysis， it is discovered that the abovementioned TCM can produce effects such as blocking the cell cycle， inducing autophagy and apoptosis， inhibiting angiogenesis， suppressing proliferation and migration， and reversing chemotherapy resistance and radiotherapy resistance by inhibiting the PI3K/Akt/mTOR pathway in CRC cells. TCM holds promise in the research and application of targeting the PI3K/Akt/mTOR signaling pathway for CRC treatment. The summary and conclusion of this article aim to provide references for subsequent research and the development of new drugs.

OBJECTIVES: To investigate the role of nucleolar pre-rRNA processing protein NIP7 (NIP7) in maintaining the malignant phenotype of anaplastic thyroid cancer (ATC) and its molecular mechanisms. METHODS: NIP7 expression in ATC tissues and its gene knock-out effects in ATC cells were analyzed using gene expression microarray (GSE33630), proteome database (IPX0008941000) and the Dependency Map database, respectively. Expression and localization of NIP7 in normal thyroid cells, papillary thyroid cancer cells, and ATC cells were detected by Western blotting. Small interfering RNA (siRNA) was transfected into ATC cells, and the knockdown efficiency of NIP7 was detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blotting. Cell proliferation was assessed by CCK-8 assay, colony formation was evaluated by colony formation assay, and tumor growth was assessed by xenograft tumor model in nude mice. SUnSET (surface sensing of translation) assay combined with co-immunoprecipitation were employed to evaluate the effect of NIP7 silencing on ubiquitin-conjugating enzyme E2 C (UBE2C) translation. Finally, gene set enrichment analysis was used to identify shared pathways of NIP7 and UBE2C, which were validated by qRT-PCR. RESULTS: Compared with normal tissues and papillary thyroid cancer, NIP7 was significantly upregulated in ATC tissues, and had a gene knock-out fitness effect on different ATC cell lines. The relative protein levels of NIP7 in ATC cells were significantly higher than those in normal thyroid follicular cells, and the protein was mainly expressed in the nucleus. NIP7 silencing significantly inhibited cell proliferation and reduced colony formation. Xenograft tumor model showed that NIP7 knockdown significantly slowed down the growth of ATC xenograft, and the tumor volume and weight were significantly lower than those in the control group (all P<0.05). NIP7 silencing downregulated the protein level of UBE2C, but did not affect the expression of UBE2C mRNA. Compared to the control group, UBE2C silencing significantly inhibited ATC cells proliferation (P<0.01) and colony formation (P<0.05). UBE2C overexpression reversed the proliferation-inhibitory effect induced by NIP7 silencing (P<0.01). Gene set enrichment analysis indicated that NIP7 and UBE2C were both involved in DNA replication. NIP7 or UBE2C silencing could significantly downregulate the expression levels of DNA polymerase epsilon, catalytic subunit 2 and replication factor C4 in DNA replication pathway. CONCLUSIONS NIP7 promotes ATC tumor growth by upregulating UBE2C to mediate DNA replication.

At present,there are many difficulties in the diagnosis and treatment of acute vestibular syndrome(AVS).For example,complex and difficult identification of the cause of disease,uneven diagnosis and treatment levels of clinical doctors,weak humanistic care awareness,lack of communication skills,intrinsic affinity and other reasons,which make it difficult for AVS patients in the process of diagnosis and treatment,and cannot receive timely and effective treatment,resulting in an exacerbation of doctor-patient conflicts.Therefore,it is recommended to explore new paths of AVS diagnosis and treatment work using the humanistic care concept,respect each other between doctors and patients,build a team of medical staff with the value orientation of"humanistic care",and promote the organic unity of theory and practice of"humanistic care",with a view to better promoting the implementation of AVS diagnosis and treatment work,helping more patients rebuild confidence,enhancing quality of life,and improving the doctor-patient relationship.

Objective:To explore the effect of comfort nursing intervention in hospice care for advanced cancer patients at home, and to provide reference for hospice care for advanced cancer patients at home.Methods:A randomized controlled trial was conducted. A total of 105 patients with advanced cancer who were treated in the Cancer Hospital Affiliated to Harbin Medical University from January to February 2023 were selected as the research objects. According to the random number table, they were divided into control group of 53 cases and intervention group of 52 cases. The control group received routine nursing methods, while the intervention group received comfort nursing interventions on this basis. The intervention lasted for 4 weeks. The changes in palliative care outcomes, quality of life and death anxiety were compared between the two groups before and after intervention.Results:Totally 105 cases were included, 53 cases in the control group and 52 cases in the intervention group. In the control group, there were 25 males, 28 females, aged (58.96 ± 10.71) years old; in the intervention group, there were 22 males, 30 females, aged (59.82 ± 10.53) years old. Before intervention, there was no statistically significant difference in palliative care outcomes, quality of life and cancer death anxiety scores between the two groups of patients (all P>0.05). After intervention, the total score of palliative care outcomes in the intervention group was (13.34 ± 5.88) points, significantly lower than (16.15 ± 5.72) points in the control group, with a statistically significant difference ( t = 2.48, P<0.05). The overall health status score of quality of life was (68.55 ± 9.34) points in the intervention group, higher than (63.01 ± 9.28) points in the control group ( t = 3.05, P<0.05). The total score of cancer death anxiety was (8.85 ± 2.72) points, significantly lower than (10.59 ± 3.14) points of the control group, with a statistically significant difference ( t = 3.04, P<0.05). Conclusions:The application of comfort nursing mode in home based hospice care can improve the quality of hospice care for advanced cancer patients, reduce their level of death anxiety, and is of great significance for improving the quality of life of advanced cancer patients.

Acute myocardial infarction(AMI)is a serious disease that endangers human life and health,timely opening of the infarct vessel is the main means of successful treatment.Emergency percutaneous coronary intervention(PCI)is the most effective treatment at present,which can quickly restore myocardial blood supply and save patients'lives.With the maturity of PCI treatment,the survival rate of patients with AMI has improved significantly.However,in recent years,emergency PCI operators have encountered a significant challenge:rare and fatal complications associated with coronary artery injury during emergency PCI are not promptly recognized and treated,leading to an increase in perioperative mortality.At present,there is no unified plan for the management of critical complications during PCI at home and abroad.Therefore,this paper mainly reviews the management measures of complications related to coronary artery injury during surgery,such as coronary artery perforation,non-reflow,coronary artery dissection,and stent thrombosis,and summarizes the progress of relevant treatment measures at home and abroad to help surgeons deal with emergencies timely and correctly and save more patient lives.

Cardiotoxicity caused by postoperative radiotherapy can increase the risk of cardiovascular adverse events in patients with breast cancer, especially those with left breast cancer, which is proportional to the dose of radiation to the heart. It has been proved that deep inspiration breath-hold (DIBH) technique can significantly reduce the cardiac dose in patients with left breast cancer, but the benefits of this technique vary greatly among different patients, and its implementation requires additional equipment, time, manpower and other resources. Hence, it is necessary to select patients who are suitable for this technique in advance. In addition to comprehensive analysis of general factors before simulation positioning that affect DIBH selection, this review also systematically summarized relevant indicators of CT simulation positioning images. These anatomical indicators included the measurement of the cardiac contact distances in parasagittal (CCD ps) plane, the lateral heart-to-chest distance (HCD), the product of maximum heart width (HW max) and the maximum heart depth (HD max) during CT simulation positioning, and the maximum heart distance, heart volume in the irradiation field (HVIF), the difference of lung volume and heart volume between free breathing (FB) and DIBH measured after CT localization. All of them showed some instructive significance for evaluating whether DIBH should be applied in tangent field based radiotherapy planning. The automatic planning (rapid plan) function in the treatment planning system could quickly predict the benefit of DIBH for breast cancer patients. The purpose of this article is to help clinicians select patients who are suitable for DIBH technique, guaranteeing that DIBH technique resources can be used reasonably.

Objectives:To study the molecular characteristics, virulence gene and resistance profiles of Staphylococcus aureus ( S. aureus, SA) isolates from bloodstream infections (BSI), so as to further understand the molecular characteristics of S. aureus in pediatric patients. Methods:A total of 53 S. aureus strains in bloodstream infections from Shanghai Children′s Hospital between 2016 and 2021 were collected. Antimicrobial susceptibility test were adopted by instrumental and disk diffusion method. Thirty-two kinds of virulence genes were detected by PCR and underwent multi-locus sequence typing (MLST), Staphylococcus protein A (spa) typing and staphylococcal chromosome cassette (staphylococcal cassette chromosome mec, SCCmec) typing characterizing methicillin-resistant Staphylococcus aureus (MRSA). Statistical analysis was performed using χ 2 test or Fisher exact test. Results:MRSA isolates accounted for 50.94% of the total(27/53), with ST398-t034-SCCmecV (6/53, 11.32%) and ST59-t437-SCCmecIV (4/53, 7.55%) as the most common MRSA clones. Methicillin-sensitive Staphylococcus aureus (MSSA) isolates occupied 49.06% (26/53), among which typing ST22-t309 (3/53, 5.66%) and ST7-t091/t1685 (2/53, 3.77% each) were prevalent. Of the 53 strains, all carried ≥6 virulence genes, 33 strains (62.26%) carried ≥10 virulence genes, including 18 strains of MSSA (69.23%) and 15 strains of MRSA (55.56%). The carriage rate of pvl gene in MSSA was higher than that of MRSA isolates (12/26, 33.33% vs. 6/27, 22.22%), and sasX was only detected in MRSA isolates (4/53, 7.55%). The resistant rates of BSI-SA isolates to penicillin, erythromycin and clindamycin were 98.11%, 49.06% and 41.51%, respectively. MRSA were more resistant to clinical antimicrobial agents than MSSA. Conclusions:MRSA strains cover a high proportion in S. aureus bloodstream infection of children, with ST398-t034 and ST59-t437 being the most common clones. The virulence gene carrying rate for BSI-SA was high with a greater pvl gene carrying rate in MSSA isolates while sasX was only detected in MRSA isolates. More clinical attention should be paid to the high resistance status and virulence genes characteristics of BSI-SA.

Objective:To investigate the Graf classification results and risk factors of infants for developmental dysplasia of the hip (DDH) by B-ultrasound screening in Tianjin.Methods:A retrospective analysis was conducted from January 2013 to December 2020 using the three-tier maternal and child health care management and the Tianjin maternal and child health information system for the early B-ultrasound screening data of 6-8 weeks old infants. The "2+1" screening model of "primary screening-re-screening-diagnostic treatment" was applied. The positive screening rate and age of infants at the time of referral for treatment in different years and different Graf classifications were analyzed, and the differences in positive infants with different sex, parity, fetal position, mode of production, gestational age, birth weight, and family history were compared. Binary logistic regression was used to analyze risk factors for DDH.Results:A total of 807 889 babies were screened, and 2 039 children (2 841 hips) were detected with B-ultrasound Graf classification count IIa and above, with the positive rate was 2.52‰ (2 039/807 889). Among the abnormal hips, 685 were type IIa(+) hips, 959 were type IIa(-) hips, 367 were type IIb hips, 262 were type IIc hips, 227 were type D hips, 265 were type III hips, and 76 were type IV hips. Type IIa(-) was the most common, accounting for 33.76% (959/2 841), type IIa(+) accounted for 24.11% (685/2 841), type D and above was 19.99%(568/2 841). The abnormality rate of the left hip was 2.02‰ (1 632/807 889), which was greater than 1.50‰ (1 209/807 889) of the right side, and the difference is statistically significant (χ 2=63.09, P<0.001). The rate of hip abnormalities in female infants was 3.27‰ (2 541/777 272), greater than 0.36‰ (300/838 506) in male infants, which the difference between the sexes had statistically significant (χ 2=1 947.871, P<0.001). The positive rate of DDH in male infants was 0.50‰ (209/419 253), and that in female infants was 4.71‰ (1 830/388 636). The detection ratio of male to female infants was 1∶8.76, and the difference in the positive rate of DDH between the sexes was statistically significant (χ 2=1 420.102, P<0.001). Different fetal position (cephalic position/breech presentation), delivery method (normal delivery/cesarean section), birth weight (normal/low weight), family history (with DDH/without DDH) showed statistically significant differences in the positive rate of DDH ( P<0.05), whereas there was no significant difference in the positive rate of DDH at different parity (first/second and above) and gestational age (term/premature) ( P>0.05). Logistic regression analysis showed that gender ( OR=10.50, P<0.001) and fetal position ( OR=3.40, P<0.001) were independent risk factors for DDH, and gestational age ( OR=0.91, P<0.001) was a protective factor for DDH. Differences in referral age of infants with different B-ultrasound Graf classification from year to year were statistically significant ( P<0.05). Conclusion:Through the "2+1" screening model of "primary screening-re-screening-diagnostic treatment", the DDH positive rate in 6-8 weeks old infants in Tianjin was 2.52‰, and the positive rate of DDH in female infants and left hip was higher. The more severe the Graf classification of B-ultrasound was, the younger the age of referral was. Women and infants with breech presentation had a higher risk of developing DDH, and the risk of DDH in preterm infants was lower.
