Objective To investigate the clinical characteristics and dosimetric parameters associated with acute hematologic toxicity (AHT) resulting from radiation-induced damage to hematopoietic organs in patients undergoing chemoradiotherapy for cervical cancer and to provide a reference for establishing dose constraints in relevant regions of interest (ROIs) and predicting adverse tissue reactions during the development of clinical treatment plans. Methods A retrospective analysis was conducted on 556 patients with cervical cancer who underwent chemoradiotherapy at our hospital. Univariate (χ² and t-test) and multivariate (binary logistic regression analyses) methods were employed to investigate the association of clinical factors and pelvic dose-volume parameters with grade ≥ 3 AHT in patients with cervical cancer. Clinical factors comprised patients’ age, clinical stage, pathologic stage, whether the patient had received chemotherapy in the radiotherapy cycle of interest, and dose-volume dosimetric parameters V_x and D_mean for pelvic bone marrow (BM) and femoral head (FH) structures. Results The incidence of AHT among the included cases was 30.4% (169/556). Chi-square analysis of the clinical factors revealed that whether the patient had received chemotherapy, patient’s age, and pathologic stage had a significant impact on AHT. Univariate analysis showed that the factors associated with AHT were mean dose, V₅, V₁₀, V₁₅, V₂₀, and V₂₅ of BM and FH; dosimetric parameters such as V₃₅ of FH had a significant impact on the development of AHT. Multivariate logistic regression analysis identified V₁₅ of pelvic BM as an independent risk factor for AHT (P=0.041), with a threshold value of 84.29% as determined by a receiver operating characteristic (ROC) curve. Conclusion Whether a patient had received chemotherapy in the radiotherapy cycle of interest, and patient’s age and pathologic stage can serve as predictors of AHT. V₁₅ of BM is an independent risk factor for AHT development. Therefore, when formulating a treatment plan, it is crucial to ensure that pelvic V₁₅ remains below 84.29% to effectively reduce the incidence of grade ≥ 3 acute bone marrow depression.

Objective:Exploration on the mechanism of acupuncture-targeted therapy for rheumatoid arthritis and identification of candidate Chinese materia medica.Methods:Targets of acupuncture for RA were collected from related literature, and GSE205962 gene chips were obtained from GEO database. The weighted co-expression network (WGCNA) was constructed by screening differentially expressed genes using R 4.3.1. The collection targets were taken to intersect with the differential genes, and the common genes were obtained for high-throughput GO and KEGG enrichment. The Hub genes were screened by constructing protein interaction networks using the String database and Cytoscape 3.9.0 software. The CIBERSORT algorithm was used to explore the mechanisms of RA immune infiltration, and finally the Coremine Medical database was applied to predict Chinese materia medica.Results:A total of 8 key targets were selected (RHOA, JAK1, FYN, LCK, STAT1, STAT3, EGF, GATA3). The results of immune infiltration analysis showed that various immune cells were closely related to the biological processes of rheumatoid arthritis, including γδ T cells, monocytes, regulatory T cells, CD8 T cells, etc. Saposheikovize Radix, Cinnamomi Ramulus, Anemarrhenae Rhizoma, Dendrobii Caulis, Rehmannine Radix, Lonicerae Japonicae Flos, Pinelliae Rhizoma, Cimicifugae Rhizoma, Poria, Stephaniae Tetrandrae Radix were the 10 kinds of commonly used key Chinese materia medica in the treatment of RA.Conclusions:Acupuncture and moxibustion may treat RA by regulating RHOA, JAK1, FYN, LCK and other core targets. This study predicts that Chinese materia medica can be used as a source of drugs for the treatment of RA, and can provide new ideas for the combination of acupuncture and medicine for the treatment of RA.

OBJECTIVE: To investigate the clinical effect the treatment of arthroscopy-assisted calcaneal spur resection combined with plantar fascia release and calcaneal decompression in the treatment of the patients with intractable calcaneal pain. METHODS: The clinical data of 50 patients with intractable heel pain from January 2016 to January 2019 were retrospectively analyzed, including 20 males and 30 females;aged from 40 to 68 years old with an average of (50.12±7.35)years old, the medical history ranged from 1 to 4 years. All patients underwent arthroscopy-assisted calcaneal spur resection combined with plantar fascia release and calcaneal decompression, and were followed up, the duration ranged from 24 to 60 months with an average of(42.00±3.28) months. All patients had obvious heel pain before surgery, and X-ray examinations often showed the presence of calcaneal spurs. In addition to the routine foot examination, the changes in the height and angle of the arch of the foot were also measured pre and post-operatively by X-ray, for the evaluation of clinical effect. The VAS system was used to evaluate the degree of foot pain;the AOFAS scoring system was used to comprehensively evaluate the foot pain, voluntary movement, gait and stability. RESULTS: The VAS decreased from (8.75±1.24) before surgery to (5.15±2.35) at 3 months after surgery, (4.07±2.53) at 6 months after surgery, and (3.95±2.44) at the last fllow-up(P<0.05). The AOFAS score increased from (53.46±4.17) before surgery to(92.46±2.53) at 3 months after surgery, (96.33±2.46) at 6 months after surgery, and (97.05±2.37) at the last follow-up(P<0.05). The arch height was (41.54±1.15) mm before operation and (41.49±1.09) mm after the operation, the difference was not statistically significant(P>0.05). The internal arch angle of the foot arch was (121±6)° before operation and (122±7)° after operation. The difference was not statistically significant(P>0.05). CONCLUSION Arthroscopy-assisted calcaneal bone spurs resection combined with plantar fascia release and calcaneal decompression exhibited great clinical effect for treating intractable heel.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

Acupoint-symptom relationship in CHENG Dan-an's Note About Treatise on Cold-Attack was analyzed based on complex network, acupoint names and indications were extracted from the book, which provided ideas and methods for promoting the modernization of acupuncture and moxibustion by using complex network technology. A total of 112 acupoints in 201 acupuncture prescriptions were included, and the total frequency of acupoints was 880 times, forming 42 034 acupoint pairs. In terms of network indexes, compared with the complex network of comprehensive acupuncture books, such as Meridian and Acupoint Science, Zhenjiu Dacheng, Acupuncture A and B Meridians formed based on the same mathematical method, the complex network model for CHENG Dan-an's Note About Treatise on Cold-Attack shows more typical small world effect, which is characterized by higher network density (6.762) and shorter average path length (1.064). This phenomenon may be related to the tongue and pulse which added the link between acupoints. For the node indexes, the analysis of topological indexes such as Page Rank shows that acupoints represented by Dazhui (GV 14) has higher compatibility value in the treatment of exogenous diseases, which further demonstrates the clinical value of eigenvector centrality in guiding intelligent compatibility of points.

The angle between the lower extremity force line and the position of the unicondylar prosthesis is an important factor affecting the long-term survival and rate clinical outcome of the unicondylar replacement prostheses. Insufficient lower limb alignment will accelerate the wear of prosthesis and reduce the survival rate of prosthesis. Excessive lower limb alignment will accelerate the progress of contralateral interventricular arthritis. It is generally believed that the lower limb force line should be corrected in mild varus after unicompartmental knee arthroplasty. However, some scholars believe that the lower limb alignment has no effect on the functional score and prosthesis survival rate after unicompartmental knee arthroplasty. The poor position of femoral and tibial prosthesis will cause unexplained pain and even prosthesis wear, but the optimal position of femoral and tibial prosthesis is controversial. It is generally believed that the posterior tibial slope should be corrected in the range of 3° to 7° in unicompartmental knee arthroplasty, but some scholars believe that excessive change of posterior tibial slope will also affect the balance of knee joint space and knee joint range of motion. This study shows that the correction of lower limb alignment to mild varus is still the best lower limb alignment for unicompartmental knee arthroplasty. The best position of femoral and tibial prosthesis needs to be confirmed by further biomechanical research. The correction of tposterior tibial slope should be changed according to the specific original dissection angle of patients before operation.

Sleep has been widely concerned by the medical field all over the world. Sleep deprivation can cause damage to organs of the human body， which is related to the occurrence of a variety of diseases. Besides， the pathological change in different organs of the human body is also a key factor that causes or aggravates insomnia. When treating insomnia and its complications， traditional Chinese medicine （TCM） focuses on the homology of the brain and heart， and insomnia is mainly treated from the five internal organs， especially the heart and liver. Sleep duration and structure change with age. The prevalence of insomnia is higher in older individuals susceptible to complications than in the younger population. In TCM， insomnia of blood deficiency and Yin deficiency is common among the elderly. Suanzaoren Tang is a classic prescription for nourishing blood and calming the mind and it is critical in the treatment of "sleeplessness due to consumptive disease and dysphoria"， with the effects of nourishing liver blood to calm the mind and clearing internal heat to relieve dysphoria. It has good efficacy on the insomnia of the elderly caused by deficiency of Qi and blood and abnormal operation of nutrient Qi and defense Qi. Furthermore， it also shows a certain therapeutic effect on insomnia combined with cardiovascular and cerebrovascular diseases. The present study revealed the damage to the brain， heart， and liver caused by sleep deprivation and the effect of Suanzaoren Tang on the brain， heart， and liver， and clarified the facts that Suanzaoren Tang inhibited the damage to organs caused by sleep deprivation and regulated energy metabolism， thereby exploring the sedative and hypnotic mechanism of Suanzaoren Tang to provide new ideas for Suanzaoren Tang in the treatment of sleep disorders and other diseases.

Aim To establish three kinds of DNA damage models of mouse testicular spermatogonia cell line GC-1 cells and analyze their similarities and differences. Methods GC-1 cells were treated with UVB irradiation, D-galactose(D-Gal) or bleomycin (BLM), respectively. Then the expression and localization of 'Y-H2AX were detected by Western blot and immunofluorescence, the expression and localization of 8-OHdG were measured by immunofluorescence, and the expression levels of p-p53 and p21 were measured by Western blot. Results The expression of -y-H2AX in GC-1 cell reached to the peak 4 h after UVB irradiation and 6 h after D-Gal stimulation, whereas -y-H2AX expression gradually increased after BLM stimulation, and the higher the concentration of BLM,the shorter the time to reach the peak. The results of immunofluorescence showed that 8-OHdG expression was observed in the nucleus and cytoplasm of GC-1 cells after UVB irradiation and BLM stimulation, and the longer the culture time, the more the expression in the nucleus. In contrast, the expression of 8-OHdG was observed in the cytoplasm and reached the peak at 6 h in the D-Gal stimulated GC-1 cells. After UVB irradiation, the protein expression levels of p-p53 gradually increased, while p21 protein expression appeared later than that of p-p53; in the D-Gal stimulated GC-1 cells, the protein expression levels of p-p53 reached the peak at 6 h, and p21 protein expression reached the peak at 12 h; after low concentration BLM stimulation, the protein expression levels of p-p53 and p21 continuously increased, and after high concentration BLM stimulation, the protein expression levels of p-p53 and p21 reached its peak at 2 h, then decreased at 4 h. Conclusions Three kinds of DNA damage models of GC-1 cells are successfully established, and the DNA damage in GC-1 cells treated with D-Gal is mild, while the DNA damage in GC-1 cells treated by UVB irradiation and BLM stimulation is more severe.
