Based on the theories of the generation and restriction relationships among the five elements and visceral manifestation theory， this paper explores the pathological evolution of the relationship between lung （metal） and liver （wood）， in which their physiological state of "restriction without harm" to pathological mutual contention and damage， referred to as "struggle between metal and wood". It is proposed that the core pathogenesis of neurodermatitis lies in the dynamic transformation of metal-wood interaction from mutual coordination to mutual struggle， eventually resulting in reciprocal damage. This pathological evolution accounts for the coexistence of pruritus and lichenification， as well as the chronic and refractory nature of the disease. Treatment should be guided by the principle of regulating and harmonizing between metal and wood. Wood is treated by softening to restore its free coursing， using modified Xiaoyao Powder （逍遥散）. Metal is treated by dispersing， descending， moistening， and nourishing to restore its characteristics of clarity， purification， and moistness， using modified Xiebai Powder （泻白散） supplemented with leaf-type herbs and other moistening agents to relieve dryness. When metal becomes depleted and wood withers， accompanied by blood deficiency with wind-dryness， treatment should emphasize the mutual generation between metal and water， and the nourishment of water to moisten wood， using self-formulated Wuzi Chengji Decoction （五子承济汤）， so as to reestablish the generation and restriction relationship.

ObjectiveTo investigate the mechanism of modified Si Junzitang and Shashen Maidong Tang ［Yiqi Yangyin Jiedu prescription （YQYYJD）］ in enhancing the sensitivity of cisplatin in epidermal growth factor receptor tyrosine kinase inhibitor （EGFR-TKI）-resistant lung adenocarcinoma cells based on aerobic glycolysis. MethodsThe effects of different concentrations of YQYYJD （0， 2， 3， 4， 5， 6， 7， 8 g·L^-1） and cisplatin （0， 3， 6， 9， 12， 15， 18， 21， 24， 27 mg·L^-1） on the proliferation and activity of PC9/GR cells were detected by the cell counting kit-8 （CCK-8） assay after 24 hours of intervention. The half-maximal inhibitory concentration （IC₅₀） for PC9/GR cells was calculated to determine the concentrations used in subsequent experiments. PC9/GR cells were divided into blank group （complete medium）， YQYYJD group （5 g·L^-1）， cisplatin group （12 mg·L^-1）， and combined group （YQYYJD 5 g·L^-1 + cisplatin 12 mg·L^-1）. After 24 hours of intervention， cell viability was measured using CCK-8 assay. Cell proliferation was assessed by colony formation assay， and cell migration was evaluated by scratch and Transwell assays. Glucose consumption， lactate production， and adenosine triphosphate （ATP） levels were measured by colorimetric assays. The expression levels of glycolysis-related proteins， including hexokinase 2 （HK2）， phosphofructokinase P （PFKP）， pyruvate kinase M2 （PKM2）， lactate dehydrogenase A （LDHA）， glucose transporter 1 （GLUT1）， and monocarboxylate transporter 4 （MCT4）， were determined by Western blot. ResultsBoth YQYYJD and cisplatin inhibited the viability of PC9/GR cells in a concentration-dependent manner. The IC₅₀ of PC9/GR cells for YQYYJD and cisplatin were 5.15 g·L^-1 and 12.91 mg·L^-1， respectively. In terms of cell proliferation， compared with the blank group， the cell survival rate and the number of colonies formed in the YQYYJD group， cisplatin group， and combined group were significantly decreased （P<0.01）. Compared with the YQYYJD and cisplatin groups， the combined group showed a further significant reduction in cell survival rate and colony formation （P<0.01）. In terms of cell migration， compared with the blank group， the cell migration rate and the number of cells passing through the Transwell membrane in the YQYYJD group， cisplatin group， and combined group were significantly decreased （P<0.01）. Compared with the YQYYJD and cisplatin groups， the combined group exhibited a further significant reduction in cell migration rate and the number of cells passing through the Transwell membrane （P<0.01）. In terms of glycolysis， compared with the blank group， glucose consumption， lactate production， and ATP levels in the YQYYJD group， cisplatin group， and combined group were significantly decreased （P<0.01）. Compared with the YQYYJD and cisplatin groups， the combined group showed a further significant reduction in glucose consumption， lactate production， and ATP levels （P<0.05）. Compared with the blank group， the protein expression levels of HK2， PFKP， PKM2， and LDHA in the YQYYJD， cisplatin， and combined groups were significantly decreased （P<0.01）. The combined group showed a further significant reduction in the expression levels of these proteins compared with the YQYYJD and cisplatin groups （P<0.01）. No significant differences were observed in the protein expression levels of GLUT1 and MCT4 among the groups. ConclusionYQYYJD can synergistically inhibit the proliferation and migration of PC9/GR cells and enhance their sensitivity to cisplatin. The mechanism may be related to the downregulation of the expression of glycolysis-related rate-limiting enzymes， including HK2， PFKP， PKM2， and LDHA， thereby inhibiting glycolysis.

OBJECTIVE To construct an evaluation index system for the core competencies of ethics committee members of drug clinical trial institution,providing a basis for optimizing the training system for committee members,improving the quality of ethical review,and fully safeguarding the safety and rights of subjects.METHODS Using methods such as literature research and expert consultation,a preliminary core competency evaluation index system was constructed.The Delphi method was employed to revise and validate it,ultimately forming an evaluation index system for the core competencies of ethics committee members.Based on this system,a questionnaire survey was conducted among 90 ethics committee members from 29 drug clinical trial institutions nationwide,comparing their importance rating and self-assessment scores of the core competency indexes.RESULTS The evaluation system constructed included 4 primary indicators(ethics and professional knowledge,ethics review ability,communication and expression ability,moral integrity and work style)and 39 secondary indicators(familiarity with the content of clinical trial-related laws and regulations,ability to complete project ethics review and identify ethical defects in research protocols within a short period of time,ability to judge the scientific value of clinical research,etc.).The results of questionnaire survey showed that the interviewed ethics committee members had significant capability gaps in dimensions such as regulatory knowledge,ethical norms,review efficiency,risk judgment,and problem analysis.The differences between the importance rating scores of corresponding secondary indicators and the self-assessment scores were all no less than 0.38.CONCLUSIONS This study has developed a quantifiable and stratified core competency assessment tool for ethics committee members.It can provide a scientific framework for committee member training,qualification certification,and standardized management of ethics committees.

Normothermic machine perfusion (NMP) is currently a research hotspot of organ preservation in the field of transplantation. Its safety and effectiveness of organ preservation have been clinically validated especially for preserving marginal donor organs. Various unique advantages of NMP are offered for in vitro organ function assessments, maintenance and organ injury repairing. Within the field of organ medicine, precise clinical interventions based upon in vivo or in vitro researches are implemented through an in vitro organ support system. With an aid of extracorporeal organ support system, an independent extracorporeal circulation system could be established for single or multiple organs more efficiently and safely. And physiological supports and other interventions for target organs are performed. Organ gene editing therapy, organ cell therapy, organ chemotherapy, organolytic virus therapy and organ physiological support therapy are all disciplines of organ quarantine therapy. This emerging theory provides a novel treatment for clinical organ diseases. This review summarized the use of NMP technology based upon the concepts and applications of organ medicine. Also the applications of organ isolation and protection therapy were discussed for organ transplantation and other research fields.

Objective:To investigate the effectiveness, safety, and advantages of modified radical neck dissection by gasless unilateral axillary approach (GUA-MRND) in the surgical management of selected patients with papillary thyroid cancer.Methods:We retrospectively analyzed patients with papillary thyroid cancer who underwent GUA-MRND (endoscopic group, n=16) versus unilateral open modified radical neck dissection (MRND) (open group, n=32) during the period from Jan. 2019 to Jun. 2021, including the differences in surgical efficiency, complication rate, and incisional satisfaction.Results:Compared MRND with GUA-MRND, the patients were younger ( P<0.05) , operative time and postoperative drainage anterior ( P<0.01) were slightly inferior in the latter, but it had obvious advantages in cervical swallowing discomfort and incision satisfaction evaluation ( P<0.05) . There was no significant difference in the incidence of temporary recurrent laryngeal nerve injury, intraoperative and postoperative bleeding, hematoma, infection, lymphatic or chylous leakage and supraclavicular numbness after surgery ( P>0.05) . The number of dissected lymph nodes in area II in the GUA-MRND was lower ( P<0.05) , but it was significantly higher ( P<0.01) in area III. And the average regional cleaning efficiency in the GUA-MRND was level Ⅲ (35.5%) , level Ⅵ (28.59%) , level Ⅳ (23.21%) , level Ⅱ (7.18%) and level Ⅴ (7.12%) , suggested that GUA-MRND had higher efficacy for level III, level Ⅵ and Level IV. Conclusion:GUA-MRND is safe, effective, and has high cosmetic satisfaction in the treatment of selected patients with lateral cervical lymph node metastases from papillary thyroid cancer.

Objective:To evaluate the value and efficacy of microscope-assisted minimally invasive anterior lumbar discectomy and zero-profile fusion (ALDF) for lumbar degenerative diseases.Methods:Anterior lumbar distractors were designed to maintain the distraction of intervertebral space and expose the posterior edge of the intervertebral space. From June 2018 to December 2020, 41 cases of lumbar degenerative diseases were treated with this operation, including 19 men and 22 women, aged 29-71 years old (average 42.1 years old). All patients had intractable low back pain. Imaging examination showed lumbar disc degeneration with narrow intervertebral space, including disc herniation with Modic changes in 7 cases, spinal stenosis with instability in 16 cases and spondylolisthesis in 18 cases. The involved levels included L 2,3 in 1 case, L 3,4 in 3 cases, L 2-L 4 in 1 case, L 4,5 in 17 cases and L 5S 1 in 19 cases. An incision was taken that was pararectus for L 2-L 4 and transverse for L 4-S 1, with the intervertebral disc exposed via extraperitoneal approach. The intervertebral space was released and distracted after discectomy in intervertebral space, and self-made distractors were used to maintain the space. Under microscope, the herniation, posterior annulus and osteophyte were removed for sufficient decompression, with a suitable self-anchoring cage implanted into the intervertebral space. The visual analogue score (VAS), Oswestry dysfunction index (ODI), intervertebral space height, lordosis angle and spondylolisthesis rate were evaluated. Results:Operations were performed successfully in all the patients. The operation time was 70-120 min with an average of 90 min, and the intraoperative blood loss was 15-70 ml with an average of 30 ml. No severe complication such as nerve or blood vessel injury occurred. The patients were followed up for 12 to 36 months, with an average of 18 months. At the last follow-up, VAS decreased from 6.4±2.3 to 1.1±0.9, and ODI decreased from 44.9%±16.9% to 5.8%±4.7%. Intervertebral space height recovered from 7.2±2.8 mm to 12.1±2.1 mm and lordosis angle recovered from 6.9°±4.8° to 10.1°±4.6°. X-ray showed significant recovery of intervertebral space height, lordosis angle and spondylolisthesis rate, with obvious interbody fusion and no displacement of cage. For 18 patients of spondylolisthesis, the slippage recovered from 16.6%±9.3% to 7.6%±5.3%, with an average improvement of 54.2%.Conclusion:Microscope-assisted minimally invasive ALDF can provide sufficient decompression and zero-profile fusion for lumbar degenerative diseases with satisfactory results during short-term follow-up.

Objective:To conduct a retrospective analysis of efficacy and safety of different conversion schemes of tacrolimus to slow-release dosage forms for recipients in stable phase after renal transplantation to provide rationales for the conversion strategy of tacrolimus.Methods:From January 2020 to June 2020, clinical data were reviewed for 101 kidney transplant recipients converting from common tacrolimus dosage form to tacrolimus sustained-release dosage form during postoperative stable period.There were 62 males and 49 females with an age range of 19 to 69 years.They were divided into two groups according to iso-dose and incremental-dose switching schemes.The common dosage form of tacrolimus was converted into a sustained-release dosage form with different conversion doses, They were divided into two groups of 1∶1 conversion( n=55)and >1∶1 conversion( n=46). The clinical parameters of serum creatinine(Scr), blood urea nitrogen(BUN), alanine aminotransferase(ALT)and aspartate aminotransferase(AST), alkaline phosphatase(ALP), serum albumin(ALB), white blood cell count(WBC), urinary white blood cell(UWBC), hemoglobin(Hb)and fasting blood glucose(Glu)were compared between two groups after conversion. Results:Regarding numerical change trend after switching to tacrolimus sustained-release dosage form, drug dose/variation trend was smaller and blood drug concentration more stabilized.In two subgroups converted by 1∶1 and 1>1 initial dose, change trend of dose/blood concentration in 1∶1 conversion group appeared to be more stable.However, no inter-group difference existed in long-term parameters.Scr was lower at 1 week and 3 months after switching to extended-release dosage form( P<0.05)and BUN was lower at 2 weeks( P<0.05). In addition, at 5 months after conversion, ALT and AST significantly improved as compared with common dosage form( P<0.05). Significant differences existed in urinary WBC(UWBC)at 2/3 weeks( P<0.05). After switching for 2 weeks, hemoglobin significantly improved compared with common dosage form( P<0.05). No significant differences existed in ALP, ALB or Glu at other timepoints and pre-conversion( P>0.05). In 1∶1 switch group, renal function tended to improve.At 2 weeks, BUN was lower than pre-conversion; at 1/3 weeks, Scr was lower than pre-conversion( P<0.05). In addition, there was also a trend of improvement in liver function in 1∶1 conversion group.At 1 week and 5 months, ALT was lower than pre-conversion( P<0.05). However, no significant differences existed in AST, ALB, ALP, Glu, UWBC and serum WBC count at each timepoint between two different dose conversion groups( P>0.05). After conversion, intra-individual variability of tacrolimus trough concentration significantly improved( P<0.05). Conclusions:With the same safety and efficacy as common dosage form, sustained-release dosage form of tacrolimus may improve drug variability of individuals.When converting common dosage form into sustained-release dosage form, individual differences should be considered.While monitoring trough concentrations, proper doses should be adjusted on the basis of various clinical parameters.
