Objective:To investigate the effects of self-made Gujin Xiaoji Mixture combined with warming needle therapy on the clinical efficacy and immune function of patients with advanced non-small cell lung cancer (NSCLC) with qi and yin deficiency syndrome.Methods:This experiment was a randomized controlled trial study. 180 patients with advanced NSCLC qi and yin deficiency syndrome in the oncology centre of Qingdao Hospital of Traditional Chinese Medicine were selected as the observation subjects from March 2021 to August 2022, and were divided into 2 groups using the random number table method, with 90 cases in each group. The control group received conventional chemotherapy combined with Sintilimab injection, 21 days as a cycle, with a total of 4 cycles of treatment; and the observation group received Gujin Xiaoji Mixture combined with warming needle therapy based on the control group, 7 days as one course of treatment, with a total of 12 courses. Both groups were followed up for 12 months. The TCM syndrome scores were performed before and after treatment. The functional assessment of cancer therapy-lung (FACT-L) was used to evaluate the quality of life of patients; flow cytometry was used to detect the levels of CD3 +, CD4 +, CD8 + and NK cell, and the CD4 +/CD8 + ratio was calculated; adverse drug reactions and progression free survival of patients during treatment were observed and recorded, the efficacy of TCM syndrome and objective efficacy of solid tumors were evaluated. Results:After treatment, the observation group's post-treatment TCM syndrome score (5.67±1.99 vs. 7.12±2.31, t=-4.53) was lower than that of the control group ( P<0.001); mobility (23.03±2.80 vs. 20.69±2.46, t=5.96), daily living (23.06±2.56 vs. 20.71± 2.33, t=6.42), emotional status (18.44±2.32 vs. 16.12±2.71, t=6.18), and other factors (33.14±4.11 vs. 27.39±4.64, t=8.81) and total score (97.68±7.23 vs. 84.91±7.49, t=11.64) were higher than those in the control group ( P<0.01). In the observation group, after treatment, the levels of CD3 + [(65.14±6.06)% vs. (59.84±5.74)%, t=6.02], CD4 + [(40.09±4.09)% vs. (35.69±3.86)%, t=7.43], NK cell [(29.11±4.81)% vs. (22.38±4.51)%, t=9.68] and CD4 +/CD8 + [(1.52±0.27) vs. (1.14±0.12), t=12.63] were higher than those in the control group ( P<0.01), and CD8 + [(26.82±3.79)% vs. (31.76±4.65)%, t=-7.81] level was lower than that of the control group ( P<0.01). After treatment, the objective remission rate in the observation group was 7.8% (7/90), and the disease control rate was 87.8% (79/90), while the objective remission rate after treatment in the control group was 5.5% (5/90), and the disease control rate was 82.2% (74/90), and there were no statistical significance in the comparison of objective remission rate and disease control rate of the 2 groups ( χ2=0.09, 0.70, P=0.765, 0.407). The total effective rate after treatment was 62.2% (56/90) in the observation group and 34.4% (31/90) in the control group, and the difference between the 2 groups was statistically significant ( Z=-3.89, P<0.001). WBC [(4.27±1.12)×10 9/L vs. (3.84±1.11)×10 9/L, t=2.58] and haemoglobin [(119.93±17.25)g/L vs. (109.76±15.61)g/L, t=4.15] levels of the observation group were higher than those in the control group after treatment ( P<0.01). During follow-up, the median progression-free survival was 6.2 months in the observation group and 5.5 months in the control group patients, and the difference between the 2 groups was not statistically different ( t=0.11, P>0.05). Conclusion:The combination of Gujin Xiaoji Mixture with warming needle therapy can effectively improve the clinical symptoms of patients with advanced NSCLC with deficiency of qi and yin syndrome, improve the immunity and clinical efficacy of patients, alleviate the adverse effects of drugs, and prolong the progression-free survival period.

Sarcopenia obesity (SO), a specific disease with co-occurrence of obesity and sarcopenia, is shown clinically as abnormal accumulation of fat, decreased mass and strength of muscle, and increased risk of incidence and mortality of other chronic diseases. Currently, there exist various definitions and diagnoses about SO in the various regions of the world. Its prevalence in populations elevates in an age-dependent manner. This article summarized the possible pathogenesis of SO from the view of chronic inflammation, oxidative stress, insulin resistance, and Hippo pathway, subsequently listed and analyzed potential pharmacological targets (fibroblast growth factor, CD44, adiponectin, etc) involved in treating SO, in order to provide new ideas for clinical diagnosis, treatment of SO patients and research and development of innovative drugs.

Objective To investigate the effect and mechanism of Huanglian Jiedu Decoction in improving the itching symptoms of 1-chloro-2,4-dinitrobenzene(DNCB)-induced atopic dermatitis(AD)in mice.Methods Thirty-six Balb/c mice were randomly divided into normal group,model group,Dexamethasone(positive control,2.5 mg·kg-1)group and Huanglian Jiedu Decoction low-,medium-and high-dose groups(0.4,0.8 and 1.6 g·kg-1),6 mice in each group.After shaving the back of the mice,200 μL of DNCB solution was applied to the back of the mice for sensitisation(1%DNCB for 3 consecutive days)and excitation(1.5%DNCB,starting from the fourteenth day,excitation was performed once every 3 days for a total of 5 times).The stimulation and drug interventions were carried out simultaneously,and each group was administered by gavage at a set dose once daily for 14 days.The severity score of the skin lesions was calculated with reference to the Scoring Atopic Dermatitis(SCORAD),and the number of times the mice scratched within 20 minutes was recorded.The pathological changes of the lesions were observed by HE staining;mast cell infiltration was observed by toluidine blue staining;and the mRNA expression levels of thymic stromal lymphopoietin(TSLP),interleukin(IL)13,histamine H4 receptor(HRH4),and IL-31 in the lesions were detected by RT-qPCR.Results Compared with the normal group,the dorsal skin of the mice in the model group showed obvious erythema,mossification,crusting and epidermal shedding after DNCB excitation,and the severity score of the lesions was significantly increased(P＜0.001);the hyperkeratosis of epidermis,the thickness of spinous layer was significantly increased(P＜0.001),sponge oedema,and a large number of inflammatory cells infiltration was seen in the dermis;and the number of mast cells was significantly increased(P＜0.001);the times of scratches within 20 minutes was significantly increased(P＜0.01);and the mRNA expression levels of TSLP,IL-13,HRH4,and IL-31 in the skin lesion tissue were all significantly elevated(P＜0.05,P＜0.01).Compared with the model group,the skin lesions on the backs of mice in the low-,medium-and high-dose groups of Huanglian Jiedu Decoction were significantly improved,the mossy area was significantly reduced,the severity was significantly reduced,and the severity score of skin lesions was significantly reduced(P＜0.001),and the number of mast cells and the mRNA expression levels of IL-13,HRH4,and IL-31 were significantly reduced in the skin lesion tissues(P＜0.05,P＜0.01,P＜0.001);the thickness of the stratum spinosum was significantly reduced in the medium-and high-dose groups of Huanglian Jiedu Decoction(P＜0.001),and the number of inflammatory cells in the dermis was significantly reduced;the number of scratching in mice in the high-dose group of Huanglian Jiedu Decoction was significantly reduced within 20 minutes(P＜0.01),and the mRNA expression level of TSLP in the lesion tissue was significantly reduced(P＜0.05).Conclusion Huanglian Jiedu Decoction can alleviate itching symptoms in AD mice,and its mechanism of action may be related to repairing the skin barrier in AD mice,attenuating the infiltration of inflammatory cells and mast cells,and down-regulating the mRNA expressions of itch-associated factors TSLP,IL-13,IL-31 and HRH4 in skin tissues.

Objective To study the effect of interlocking intramedullary nail on fixing transverse olecranon fracture. Methods Nine pairs of fresh ulna specimens were collected and the transverse fracture model of olecranon was established. Kirschner wire tension band and interlocking intramedullary nail were used to repair the fracture. Cyclic dynamic tension loads with amplitude of 25 N, mean value of 45 N and frequency of 05 Hz were applied to the triceps tendon under simulated elbow flexion conditions of 30°, 45° and 60°, respectively. The fracture displacements of specimens within 300 cycles were recorded in three groups. ResultsAt 30° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.831±0.333) mm and (3.723±2.390) mm, respectively. At 45° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.167±0.374) mm and (2.455±0.609) mm, respectively. At 60° flexion angle, the fracture displacement of interlocking intramedullary nail group and Kirschner wire tension band group was (1.407±0.342) mm and (3.112±1.025) mm, respectively. The fracture displacement of interlocking intramedullary nail was smaller. Conclusions The mechanical properties of interlocking intramedullary nail are better than those of Kirschner wire tension band, and the interlocking intramedullary nail is more stable and firmer for fixing transverse olecranon fracture. Moreover, the interlocking intramedullary nail is installed with the operating tool, thus the operation is more accurate and faster, and the operation efficiency is greatly improved.

Objective : To explore the relationship between geriatric nutritional risk index( GNRI) and perioperative nutritional status，postoperative recovery and complications in elderly patients with gastric cancer． Methods : In this retrospective study，212 elderly patients ( aged ≥60 years ) with gastric cancer who underwent gastrectomy were recruited．GNRI was used to retrospectively assess the patients' preoperative nutritional status ，and analyze the relationship between GNRI and perioperative nutritional status，postoperative recovery and complications．The ROC curve was applied to explore the value of GNRI in predicting postoperative complications. Results : The inci- dence of preoperative nutritional risk in elderly patients undergoing gastric cancer surgery was 45. 07%．Compared with the patients whose GNRI＞98 points，the patients whose GNRI≤98 points had different degrees of decrease in serum total protein，albumin，prealbumin，hemoglobin and lymphocyte counts before surgery，day 1 and day 5－8 after surgery (P ＜0. 05) ．The patients whose GNRI ＜92 points had longer postoperative hospital stay than those with GNRI＞98 points (P＜0. 05) ．With the decrease of GNRI scores，the incidence of complications showed an upward trend(P＜0. 001) ．The multivariate analysis of the relationship between GNRI and postoperative complica- tions showed that TNM staging of III －IV and GNRI ＜92 points were independent risk factors for complications. GNRI had a good predictive value for the occurrence of complications (AUC = 0. 639，95% CI : 0. 570－0. 703，P = 0. 001，Cut-off value : 92. 21) ． Conclusion GNRI can be used for preoperative nutritional assessment for eld- erly gastric cancer patients．Patients with GNRI＜92. 21 points should be actively given nutritional therapy to im- prove perioperative nutritional status，speed up postoperative recovery，and reduce the occurrence of complications.

Objective:To analyze the incidence and epidemiological characteristics of traumatic spinal cord injury in China in 2018.Methods:Multi-stage stratified cluster sampling was used to randomly select hospitals capable of treating patients with spinal cord injury from 3 regions，9 provinces and 27 cities in China to retrospectively investigate eligible patients with traumatic spinal cord injury admitted in 2018. National and regional incidence rates were calculated. The data of cause of injury，injury level，severity of injury，segment and type of fracture，complications，death and other data were collected by medical record questionnaire，and analyzed according to geographical region，age and gender.Results:Medical records of 4，134 patients were included in this study，with a male-to-female ratio of 2.99∶1. The incidence of traumatic spinal cord injury in China in 2018 was 50.484 / 1 million （95% CI 50.122-50.846）. The highest incidence in the Eastern region was 53.791 / 1 million （95% CI 53.217-54.365）. In the whole country，the main causes of injury were high falls （29.58%），as well as in the Western region （40.68%），while the main causes of injury in the Eastern and Central regions were traffic injuries （31.22%，30.10%）. The main injury level was cervical spinal cord in the whole country （64.49%），and the proportion of cervical spinal cord injury in the Central region was the highest （74.68%），and the proportion of lumbosacral spinal cord injury in the Western region was the highest （32.30%）. The highest proportion of degree of injury was incomplete quadriplegia （55.20%），and the distribution pattern was the same in each region. A total of 65.87% of the patients were complicated with fracture or dislocation，77.95% in the Western region and only 54.77% in the Central region. In the whole country，the head was the main combined injury （37.87%），as well as in the Eastern and Central regions，while the proportion of chest combined injury in the Western region was the highest （38.57%）. A total of 32.90% of the patients were complicated with respiratory complications. There were 23 patients （0.56%） died in hospital，of which 17（73.91%） died of respiratory dysfunction. Conclusions:The Eastern region of China has a high incidence of traumatic spinal cord injury. Other epidemiological features include high fall as the main cause of injury cervical spinal cord injury as the main injury level，incomplete quadriplegia as the main degree of injury，head as the main combined injury，and respiratory complications as the main complication.

Objective:To report two cases of steroid-resistant nephrotic syndrome (SRNS) caused by LAMB2 gene mutation, and summarize the characteristics of genotype, clinical and pathological phenotypes of children with LAMB2 gene mutation. Methods:Two cases with SRNS caused by LAMB2 gene mutation were from Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology in December 2013 and September 2019. The demographic, family history and clinical data of two cases were collected, and the peripheral blood genomic DNA was captured and sequenced by whole exome sequencing. PubMed, Medline, CNKI and Wanfang databases were searched to summarize the clinicopathological phenotypes and genotypes of patients with LAMB2 mutation. Results:Among the two cases with SRNS caused by LAMB2 gene mutation, the clinical phenotypes were all manifested as nephrotic level of proteinuria and hypoalbuminemia, and there was no extrarenal clinical manifestation. One case presented with basement membrane delamination and the other with focal segmental glomerulosclerosis (FSGS). LAMB2 mutations of two cases were Exon32 c.5390G>T(p.Cys1797Phe), Exon19 c.2557C>T(p.Arg853*) and Exon27 c.4370G>A(p.R1457Q), Exon23 c.3325G>A(p.E1109K), respectively. In literature retrieval, there were 37 cases with LAMB2 gene mutation, including 24 cases with renal biopsy data, 13 cases of focal segmental glomerulosclerosis (FSGS), 4 cases of minimal change disease, one case of diffuse mesangial sclerosis, one case of IgM nephropathy, two cases of thin basement membrane nephropathy, and three cases of mesangial hyperplasia. Among them, eight cases had basement membrane delamination tear. Among the 37 cases, 11 cases were homozygous, 22 cases were complex heterozygosity, and 4 cases were heterozygous mutation. Conclusions:LAMB2 mutation may cause delamination tear of glomerular basement membrane. The clinical phenotype is congenital nephrotic syndrome or SRNS. The literature review shows the extrarenal manifestations caused by LAMB2 mutation are mostly various ocular abnormalities, as well as respiratory, digestive and nervous system abnormalities, and the time of progression to end-stage renal disease is also different.

Objective:To study the epidemic and etiologic characteristics of influenza virus(Flu)and respiratory syncytial virus (RSV) infections in outpatient influenza-like illness(ILI)cases of children under 10 years of age in Gansu province in 2018 And to provide evidences for diagnosis, treatment, control and prevention of Flu and RSV infections in Gansu province.Methods:A total of 8 559 pharyngeal swab samples of ILI outpatients cases were tested with real-time fluorescent PCR to detect Flu, 3 436 of which were detected by RT-PCR for RSV.Results:Of the 8559 specimens, 934 (10.91%) samples were positive for Flu. Among them, 431 were positive for H1N1, 70 were positive for H3N2, 428 were positive for Flu B, 5 were mixed; 320 of the 3436 (9.31%, ) samples were positive for RSV. There were significant differences in the positive rates of Flu and RSV among 14 cities and prefectures ( χ2=56.99, χ2=263.34, Р< 0.01). Influenza reached its peak in January 2018 with a positive rate of 50.70%. Flu B/Yamagata strain (53.53%) and A H1N1 (39.93%) were prevalent simultaneously. The peak of RSV epidemic was from February to April, the positive rate was 13.98%. The RSV positive rate of children under 5 years of age was 10.11%, higher than that of children over 5 years of age was 6.94%. There was statistical significance ( χ2=7.67, Р<0.01). Conclusions:RSV and influenza viruses are the main pathogens in ILI cases of children under 10 years of age. There are epidemic peaks in winter and spring every year. It is suggested that the monitoring of RSV and the development and application of vaccine should be strengthened.

Objective:To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China.Methods:A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014.Results:Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade Ⅱ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively.Conclusions:The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.
