Cervi Cornu Pantotrichum is a precious animal-derived Chinese medicinal material, while there are often adulterants derived from animals not specified in the Chinese Pharmacopeia in the market, which disturbs the safety of medication. This study was conducted with the aim of strengthening the quality control of Cervi Cornu Pantotrichum and standardizing the medication. To achieve digital identification of Cervi Cornu Pantotrichum from different sources, a digital identification model was constructed based on ultra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry(UHPLC-QTOF-MS~E) combined with an adaptive boosting algorithm(Adaboost). The young furred antlers of sika deer, red deer, elk, and reindeer were processed and then subjected to polypeptide analysis by UHPLC-QTOF-MS~E. Then, the mass spectral data reflecting the polypeptide information were obtained by digital quantification. Next, the key data were obtained by feature screening based on Gini index, and the digital identification model was constructed by Adaboost. The model was evaluated based on the recall rate, F_1 composite score, and accuracy. Finally, the results of identification based on the constructed digital identification model were validated. The results showed that when the Gini index was used to screen the data of top 100 characteristic polypeptides, the digital identification model based on Adaboost had the best performance, with the recall rate, F_1 composite score, and accuracy not less than 0.953. The validation analysis showed that the accuracy of the identification of the 10 batches of samples was as high as 100.0%. Therefore, based on UHPLC-QTOF-MS~E and Adaboost algorithm, the digital identification of Cervi Cornu Pantotrichum can be realized efficiently and accurately, which can provide reference for the quality control and original animal identification of Cervi Cornu Pantotrichum.

Glucocorticoid-induced osteoporosis(GIOP) is a serious metabolic bone disease caused by long-term application of glucocorticoids(GCs). Traditional Chinese medicine(TCM) has unique advantages in improving bone microstructure and antagonizing hormone toxicity. This paper systematically reviews the theoretical research, clinical application, and basic research progress of TCM intervention in GIOP. In terms of theoretical research, the theory of "kidney governing bone and generating marrow" indicates that the kidney is closely related to bone development, revealing that core pathogenesis of GIOP is Yin-Yang disharmony, which can be discussed using the theories of "Yin fire", "ministerial fire", and "Yang pathogen damaging Yin". Thus, regulating Yin and Yang is the basic principle to treat GIOP. In terms of clinical application, effective empirical prescriptions(such as Bushen Zhuanggu Decoction, Bushen Jiangu Decoction, and Zibu Ganshen Formula) and Chinese patent medicines(Gushukang Capsules, Hugu Capsules, Xianling Gubao Capsules, etc.) can effectively increase bone mineral density(BMD) and improve calcium and phosphorus metabolism. The combination of traditional Chinese and western medicine can reduce the risk of fracture and play an anti-GIOP role. In terms of basic research, it has been clarified that active ingredients of TCM(such as fraxetin, ginsenoside Rg_1, and salidroside) reduce bone loss and promote bone formation by inhibiting oxidative stress, ferroptosis, and other pathways, effectively improving bone homeostasis. Additionally, classical prescriptions(Modified Yiguan Decoction, Modified Qing'e Pills, Zuogui Pills, etc.) and Chinese patent medicines(Gushukang Granules, Lurong Jiangu Dropping Pills, Gubao Capsules, etc.) can improve bone marrow microcirculation, promote osteoblast differentiation, and inhibit bone cell apoptosis through multiple pathways, multiple targets, and multiple mechanisms. Through the above three aspects, the TCM research status on GIOP is elucidated in the expectation of providing reference for its diagnosis and treatment using traditional Chinese and western medicine treatment programs.

PURPOSE: The rate of complications among patients undergoing surgery has increased due to infection with SARS-CoV-2 and other variants of concern. However, Omicron has shown decreased pathogenicity, raising questions about the risk of postoperative complications among patients who are infected with this variant. This study aimed to investigate complications and related factors among patients with recent Omicron infection prior to undergoing orthopedic surgery. METHODS: A historical control study was conducted. Data were collected from all patients who underwent surgery during 2 distinct periods: (1) between Dec 12, 2022 and Jan 31, 2023 (COVID-19 positive group), (2) between Dec 12, 2021 and Jan 31, 2022 (COVID-19 negative control group). The patients were at least 18 years old. Patients who received conservative treatment after admission or had high-risk diseases or special circumstances (use of anticoagulants before surgery) were excluded from the study. The study outcomes were the total complication rate and related factors. Binary logistic regression analysis was used to identify related factors, and odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the impact of COVID-19 infection on complications. RESULTS: In the analysis, a total of 847 patients who underwent surgery were included, with 275 of these patients testing positive for COVID-19 and 572 testing negative. The COVID-19-positive group had a significantly higher rate of total complications (11.27%) than the control group (4.90%, p < 0.001). After adjusting for relevant factors, the OR was 3.08 (95% CI: 1.45-6.53). Patients who were diagnosed with COVID-19 at 3-4 weeks (OR = 0.20 (95% CI: 0.06-0.59), p = 0.005), 5-6 weeks (OR = 0.16 (95% CI: 0.04-0.59), p = 0.010), or ≥7 weeks (OR = 0.26 (95% CI: 0.06-1.02), p = 0.069) prior to surgery had a lower risk of complications than those who were diagnosed at 0-2 weeks prior to surgery. Seven factors (age, indications for surgery, time of operation, time of COVID-19 diagnosis prior to surgery, C-reactive protein levels, alanine transaminase levels, and aspartate aminotransferase levels) were found to be associated with complications; thus, these factors were used to create a nomogram. CONCLUSION Omicron continues to be a significant factor in the incidence of postoperative complications among patients undergoing orthopedic surgery. By identifying the factors associated with these complications, we can determine the optimal surgical timing, provide more accurate prognostic information, and offer appropriate consultation for orthopedic surgery patients who have been infected with Omicron.

OBJECTIVE: Huachansu injection (HCSI), a promising anti-cancer Chinese medicine injection, has been reported to have the potential for reducing the toxicity of chemotherapy and improving the quality of life for colorectal cancer (CRC) patients. The objective of this study is to explore the synergistic and detoxifying effects of HCSI when used in combination with irinotecan (CPT-11). METHODS: To investigate the effect of HCSI on anti-CRC efficacy and intestinal toxicity of CPT-11, we measured changes in the biological behavior of LoVo cells in vitro, and anti-tumor effects in LoVo cell xenograft nude mice models in vivo. Meanwhile, the effect of HCSI on intestinal toxicity and the uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1) expression was investigated in the CPT-11-induced colitis mouse model. Subsequently, we measured the effect of HCSI and its 13 constituent bufadienolides on the expression of UGT1A1 and organic anion transporting polypeptides 1B3 (OATP1B3) in HepG2 cells. RESULTS: The combination index (CI) results showed that the combination of HCSI and CPT-11 exhibited a synergistic effect (CI < 1), which significantly suppressing the LoVo cell migration, enhancing G2/M and S phase arrest, and inhibiting tumor growth in vivo. Additionally, the damage to intestinal tissues was attenuated by HCSI in CPT-11-induced colitis model, while the increased expression of UGT1A1 in HepG2 cells and in mouse was observed. CONCLUSION The co-therapy with HCSI alleviated the intestinal toxicity induced by CPT-11 and exerted an enhanced anti-CRC effect. The detoxifying mechanism may be related to the increased expression of UGT1A1 and OATP1B3 by HCSI and its bufadienolides components. The findings of this study may serve as a theoretical insights and strategies to improve CRC patient outcomes.

Octapeptin has strong antibacterial activity against Gram-negative bacteria such as Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii, while it also has activity against some Gram-positive bacteria. This study used natural octapeptin A3 and B3 as lead compounds for structural modification. Twenty-one peptide derivatives (including A3 and B3) containing eight amino acid residues were prepared by solid-phase synthesis, and evaluated for antibacterial activity and renal cytotoxicity. Among them, three compounds 6, 7 and 17 exhibited broad-spectrum antibacterial activity and significantly enhanced the activity for Gram-positive bacteria while maintaining the activity of Gram-negative bacteria. Several compounds improved the activity for Pseudomonas aeruginosa. Compound 7 was active against all test strains and had relatively low renal cytotoxicity. The results provide a basis for the further development of novel polypeptide antibiotics.

Objective:To explore the effects of hypoxia on traumatic brain swelling (TBS) in rats with acute subdural hematoma (ASDH).Methods:Forty-five SD rats were divided into 5 groups according to the random number table method, with 9 rats in each group: sham surgery normal oxygen group which underwent sham surgical procedures and were placed in a closed container with ventilation, sham surgery hypoxia group which underwent sham surgical procedures and were placed in a closed container with oxygen volume fraction of 8% for hypoxia induction, ASDH normal oxygen group which made into the ASDH model and placed in a closed container with ventilation, ASDH hypoxia group were made into the ASDH models and placed in a closed container with oxygen volume fraction of 8% for hypoxia induction, and ASDH hypoxia+oxygen inhalation group which inhaled oxygen continuously with oxygen volume fraction of 40% after being made into the ASDH models and induced for hypoxia. Six rats were selected from each group immediately after the modeling and craniotomy was performed to observe the brain swelling during the surgery and evaluate the degree of TBS. Microvascular blood flow was observed by laser speckle imaging system before modeling, before craniotomy, and immediately after craniotomy. The remaining 3 rats in each group were killed directly after modeling and brain tissue specimens were collected. The expression levels of pericellular protein α-smooth muscle actin (α-SMA) and platelet-derived growth factor receptor-β (PDGFR-β) at 0, 30 and 60 minutes after modeling were detected through Western blot analysis. The expression levels of α-SMA, PDGFR-β and microvascular marker platelet-endothelial cell adhesion molecule 31 (CD31) at 0 minute after modeling were tested through immunofluorescent staining.Results:No brain bulge was observed in the sham surgery normal oxygen group. The height of brain bulge in sham surgery hypoxia group was 0.5(0.0, 1.0)mm, with no significant difference from that in the sham surgery normal oxygen group ( P>0.05); it was 2.2(2, 2.5)mm in the ASDH normal oxygen group, significantly higher than that in the sham surgery normal oxygen group and sham surgery hypoxia group ( P<0.01), it was 3.1(2.9, 3.2)mm in the ASDH hypoxia group, significantly higher than that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.01); it was 2.8(2.7, 2.9)mm in the ASDH hypoxia+oxygen inhalation group, not statistically different from that in the ASDH hypoxia group ( P>0.05), but significantly increased compared with that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.01). Before modeling, before craniotomy and after craniotomy, the microvascular blood flow was 224.2±49.7, 224.8±50.3, 225.1±50.3 respectively in the sham surgery normal oxygen group and 224.7±43.7, 220.9±45.9, 221.8±45.5 respectively in the sham surgery hypoxia group, with no significant difference between the two groups ( P>0.05); it was 226.5±52.7, 173.4±40.7, 172.0±40.7 respectively in the ASDH normal oxygen group, significantly decreased compared with that in the sham surgery normal oxygen group and sham surgery hypoxia group ( P<0.05); it was 225.7±46.4, 131.4±23.6 and 131.0±23.5 respectively in the ASDH hypoxia group, significantly decreased compared with that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.05); it was 226.2±56.1, 132.6±21.7 and 131.7±21.9 respectively in ASDH hypoxia+oxygen inhalation group, significantly decreased compared with that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.05), with no significant difference from that in the ASDH hypoxia group ( P>0.05).

At 0 minute after modeling, the fluorescence expression of α-SMA and PDGFR-β was weaker in the sham surgery normal oxygen group and the fluorescence expression of CD31 was stronger. There was no significant difference in the fluorescence expressions of α-SMA, PDGFR-β and CD31 between the sham surgery hypoxia group and sham surgery normal oxygen group. The fluorescence expressions of α-SMA and PDGFR-β in the ASDH normal oxygen group were stronger than those in the sham surgery normal oxygen group and sham surgery hypoxia group, while the fluorescence expression of CD31 was weaker. The fluorescence expressions of α-SMA and PDGFR-β in ASDH hypoxia group were stronger than those in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group, while the fluorescence expression of CD31 was weaker. The fluorescence expressions of α-SMA and PDGFR-β in the ASDH hypoxia+oxygen inhalation group were stronger than those in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group, while the fluorescence expression of CD31 was weaker, with no significant difference from the fluorescence expressions of α-SMA, PDGFR-β and CD31 in ASDH hypoxia group. Conclusions:Hypoxia in ASDH rats will stimulate pericytes contraction, which causes cerebral microcirculatory disturbance, thus leading to TBS. Short-term inhalation of oxygen of medium concentration cannot dilate pericytes or microcirculation vessels, with no obvious effect on improving the conditions of TBS.

Objective:To identify the risk factors affecting the healing of defective bony nonunion.Methods:The studies reporting the risk factors for healing of defective bony nonunion between January 2000 and March 2022 were retrieved by computer from the VIP, Wanfangdata, CNKI, Web of Science, PubMed, and Medline databases. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the included studies. the RevMan 5.3 software was used to perform a meta-analysis of the general factors, injuries and surgical-related factors affecting the healing of defective bony nonunion.Results:Included in this Meta analysis were 17 studies with 1,236 patients. The NOS score of the included studies was from 5 to 8. The meta-analysis showed the following: age ( MD=-4.27, 95% CI: -8.29 to 2.91, P < 0.01), smoking ( OR=3.56, 95% CI: 2.81 to 6.32, P < 0.01), soft tissue defect ( OR=3.54, 95% CI: 2.21 to 5.69, P < 0.01), combined ipsilateral fibular fracture ( OR=4.18, 95% CI: 1.24 to 14.03, P=0.02), venous thrombosis ( OR=4.27, 95% CI: 1.05 to 17.44, P=0.04), and postoperative infection ( OR=2.96, 95% CI: 1.97 to 4.47, P < 0.01) were significant risk factors for the healing of defective bone nonunion. Minor bone defect ( SMD=-0.67, 95% CI: -1.25 to -0.10, P=0.02), proximal to distal bone transport ( OR=-0.42, 95% CI: 0.22 to 0.77, P < 0.01), short-term external fixation ( MD=-3.92, 95% CI: -7.10 to -0.73, P=0.02), and autologous bone grafting ( OR=0.39, 95% CI: 0.16 to 0.95, P=0.04) were protective factors for the healing of defective bony nonunion. Conclusions:High age (senility), smoking, soft tissue defect, ipsilateral fibular fracture, venous thrombosis, and postoperative infection are risk factors affecting the healing of defective bony nonunion. Minor bone defect, proximal to distal bone transport, short-term external fixation, and autologous bone grafting are protective factors affecting the healing of defective bony nonunion. Surgeons can predict early the prognosis of patients with defective bony nonunion based on the above factors.
