Objective To compare the efficacy and safety of different cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) combined with endocrine therapy (ET) for the treatment of hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2−) advanced or metastatic breast cancer. Methods Randomized controlled trials (RCTs) on CDK4/6i for the treatment of HR+/HER2− metastatic or advanced breast cancer were retrieved from databases including PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP, and SinoMed, with the search period ranging from database inception to August 2023. Bayesian network meta-analysis was conducted using R 4.2.0 software. Results A total of 18 RCTs from 25 articles, involving 8 031 patients and 11 treatment regimens, were included. There was no significant difference in progression-free survival (PFS) or overall survival (OS) among different CDK4/6i+ET combinations. The highest cumulative probability for PFS was observed with dalpiciclib (DAL)+fulvestrant (FUL), while ribociclib (RIB)+FUL ranked first for OS. In terms of efficacy, abemaciclib (ABE)+aromatase inhibitors (AI) and ABE+FUL ranked first in objective response rate and clinical benefit rate, respectively. Regarding safety, statistically significant difference in grade 3-4 adverse events was observed among certain types of CDK4/6i (P<0.05). Conclusion Current evidence suggests that CDK4/6i+ET is superior to ET alone for the treatment of HR+/HER2− advanced/metastatic breast cancer. Different CDK4/6i+ET combinations demonstrate comparable or similar efficacy; however, the incidence of adverse reactions is higher with combination therapy. Treatment regimens should be selected based on individual conditions.

Objective To study the safety and effectiveness of arc edge needle therapy for moderate to severe tenosynovitis of the flexor digitorum tendon in the thumb.Methods A total of 62 patients with moderate to severe stenosing tenosynovitis of the flexor digitorum thumb who met the inclusion criteria were collected.The patients were randomly assigned 1:1 to the arc edge needle group and the needle knife group using a random number table method.Among them,31 patients in the arc edge needle group were treated with arc edge needles,while 31 patients in the needle knife group were treated with traditional needle knife release surgery.Both groups were treated once.Record the number rating scale(NRS),range of motion(ROM),Quinell grade,and disease efficacy score(WDES)of patients before and after treatment at various stages(1 week,2 weeks,4 weeks),and at follow-up after 24 weeks to evaluate the treatment effect.Results During the 24 weeks follow-up of 62 patients after treatment,the Quinell grading comparison between the two groups showed that the arc edge needle group was better than the needle knife group(P<0.05);The total effective rate of disease efficacy score(WDES)was 96.77%in the arc edge needle group and 83.87%in the needle knife group.The clinical total effective rate of the arc edge needle group was better than that of the needle knife group(P<0.05);After treatment,both groups showed significant improvement in pain numerical score(NRS)and joint range of motion(ROM),and the degree of improvement increased over time(P<0.05);And the inter group comparison at 1 week,2 weeks,4 weeks and 24 weeks time points after treatment showed that the curved blade needle was superior to the needle knife group in improving pain and joint mobility(P<0.05).Conclusion Both the 45° tenosynovitis incision and release surgery with arc edge needle and traditional needle knife release surgery are effective in treating moderate to severe tenosynovitis of the thumb flexor digitorum tendon.However,the 45° tenosynovitis incision and release surgery with arc edge needle has significant advantages in improving pain,interphalangeal joint mobility,and safety.

Objective To explore the value of plaque-to-aorta CT value ratio(standardized CT value)in differentiating coronary lipid and fibrous plaques,and to preliminarily analyze the stability of the cutoff.Methods Patients who underwent coronary computed tomography angiography(CCTA)and intravascular ultrasound(IVUS)within 1 week were included.The plaque CT value was obtained by measuring the all,four and two short-axis planes,respectively.The CT value of the ascending aorta was measured and standardized(plaque-to-aorta CT value ratio).The receiver operating characteristic(ROC)curves of the standardized and the traditional CT values were drawn.Results A total of 60 patients with 74 plaques were included,35 lipid and 39 fibrous plaques were diagnosed by IVUS.The aorta CT value was significantly correlated with the plaque(r=0.420,P<0.01);the cutoffs for the CT value of all,four and two plaque slices were 55 HU,48 HU and 52 HU,respectively,and all there of the cutoffs of standardized CT value were 0.149;the sensitivity,specificity,positive predictive value(PPV)and negative predictive value(NPV)of four-slice traditional and standardized CT values to differentiate lipid and fibrous plaques were 69%,87%,83%,76%and 91%,82%,82%,91%,respectively.Conclusion Compared with traditional CT value,the standardized CT value can greatly improve the sensitivity and NPV in differentiating coronary lipid and fibrous plaques,while maintaining modest to high specificity and PPV.Furthermore,the cutoff is stable.

Objective To explore the clinical efficacy of arc-edge needle therapy based on Zaodian theory in the treatment of refractory tennis elbow.Methods 64 patients with refractory tennis elbow were collected and randomly divided into a control group and an observation group using a random number table method.Among them,32 cases in the control group were treated with local pain point injection.32 patients in the observation group were treated with arc-edge needle therapy once a week,with two treatments per group.The Number rating scale(NRS)Mayo,elbow joint performance score(MEPS)and Disabilities of the arm,shoulder and hand(DASH)score were recorded and compared between the two groups before treatment and at 1,2,4 and 24 weeks of follow-up after treatment,disease efficacy score(WDES)at 24 weeks of follow-up.Results During the treat-ment process,neither group of patients experienced serious adverse reactions.At each stage after treatment,two groups of NRS MEPS,DASH,and WDES at 24 weeks of follow-up all improved compared to before treatment.After one week of treatment,there was no statistically significant difference in NRS scores between the two groups(P>0.05).At follow-up visits at weeks 2,4,and 24,the NRS scores in the observation group were lower than those in the control group.After 1,2,4,and 24 weeks of follow-up after treatment,the DASH score was lower in the observation group than in the control group,and the MEPS score was higher in the observation group than in the control group,with statistically significant differences(P<0.05).After 24 weeks of treatment,the WDES of the observation group was better than that of the control group,and the difference was statistically significant(P<0.05).Conclusion Local pain point injection and arc-edge Zaodian release can alleviate pain and improve elbow joint function in the early stage of refractory tennis elbow.However,the long-term effect of local pain point injection treatment is not good,and the treatment effect of the observation group gradually improves.

Objective:To investigate the correlation between preoperative platelet parameters and the clinicopathological features of differentiated thyroid cancer. Methods:We retrospectively analyzed the medical records of patients with thyroid tumors admitted to Zhongda Hospital affiliated to Southeast University and healthy adults with normal physical examination results in our hospital from January 2019 to December 2020, and collected their general information and preoperative blood routine data. Patients with undifferentiated thyroid cancer, diabetes, coronary heart disease, hematological diseases, kidney diseases, autoimmune diseases, genetic diseases, infectious diseases, other systemic tumors, hepatitis or cirrhosis, or those taking anticoagulants were excluded. The exclusion criteria for healthy adults were the absence of the above diseases and normal physical examination results. Differences in platelet parameters among the three groups were compared, and the correlation between clinicopathological characteristics of thyroid cancer, accompanying cervical lymph node metastasis, and platelet parameters of patients was analyzed. A multivariate logistic regression model was used to analyze the risk factors of thyroid cancer with cervical lymph node metastasis. Results:A total of 117 cases of differentiated thyroid cancer were collected, including 33 males and 84 females, with an average age of （41.64±12.25） years; 46 patients had benign thyroid tumors, including 15 males and 31 females, with an average age of （41.35±12.52） years; 50 healthy adults with normal physical examination results in our hospital during the same period were also included, including 18 males and 32 females, with an average age of（42.02±9.62） years, without underlying diseases. The platelet count of the differentiated thyroid cancer group was higher than that of the benign thyroid tumor group（t=-2.219, P=0.028） and the normal control group（t=2.069, P=0.04）, while the platelet distribution width of the differentiated thyroid cancer group was lower than that of the benign thyroid tumor group（t=2.238, P=0.027） and the normal control group（t=-2.618, P=0.002）. These differences were statistically significant. Preoperative age ≤45 years（χ²=4.225, P=0.04）, tumor diameter>1 cm（χ²=4.415, P=0.036）, PLT（t=-4.018, P<0.01） increase, and PDW（t=4.568, P<0.01） decrease were significantly correlated with cervical lymph node metastasis of thyroid cancer and had statistical significance. Univariate analysis showed that age ≤45 years（OR=0.447, 95%CI 0.206-0.970, P=0.042）, tumor diameter>1 cm（OR=2.3, 95%CI 1.050-5.039, P=0.037）, PLT（OR=1.012, 95%CI 1.005-1.019, P=0.001）, and PDW（OR=0.693, 95%CI 0.518-0.827, P<0.01） were risk factors for cervical lymph node metastasis of thyroid cancer. The results of multifactorial logistic regression analysis showed that PLT（OR=1.008, 95%CI 1.001-1.016, P=0.026） and PDW（OR=0.692, 95%CI 0.564-0.848, P<0.01） were independent risk factors for thyroid cancer with cervical lymph node metastasis. Conclusion:PLT and PDW may be useful predictive factors for the differentiation of thyroid cancer malignancy and central lymph node metastasis.

Objective:To observe the effect of well-designed board sanding training on the upper extremity motor functioning of hemiplegic stroke survivors.Methods:Sixty stroke survivors with hemiplegia were randomly divided into an observation group (30 cases) and a control group (30 cases). All received conventional rehabilitation. The observation group′s training involved intelligent board sanding, while the control group′s training involved traditional sanding.Results:After the treatment, significant improvement was observed in the Fugl-Meyer upper extremity scores, modified Barthel index scores and reported shoulder pain in both groups, with the observation group′s averages significantly better than those of the control group. After the intervention, the average scores of both groups on the modified Ashforth scale had also improved significantly.Conclusions:Supplementing conventional rehabilitation treatment with intelligent board sanding can significantly improve upper extremity motor function and ability in the activities of daily living of stroke survivors with hemiplegia while somewhat relieving shoulder pain. The effect is better than with traditional board sanding.

Objective: To compare laparoscopic cholecystectomy (LC) with or without percutaneous transhepatic gallbladder drainage (PTGD) for acute severe cholecystitis. Methods: According to the predefined inclusion and exclusion criteria, 23 articles were selected for this meta-analysis. All patients were treated with LC with or without PTGD. A meta-analysis was used to analyze the clinical efficacy. Results: Compared with LC, all the surgical indicators of LC with PTGD were significantly better than LC alone (all P≤0.05), including the operation time: 95%CI(-27.24, -9.27); intraoperative blood loss: 95%CI(-50.25, -40.19); postoperative hospital stay: 95%CI(-3.63, -0.64); rates of conversion to open abdomen: OR=0.48, 95%CI(0.32, 0.74); rates of incision infection: OR=0.49, 95%CI(0.25, 0.99); drainage tube indwelling time: 95%CI(-2.07, -1.19); gastrointestinal function recovery time: 95%CI(-1.73, -0.77); rates of bile leakage: OR=0.23, 95%CI(0.12, 0.44); and rates of complications: OR=0.36, 95%CI(0.27, 0.48). Conclusion Compared with LC alone, PTGD+ LC is the preferred treatment for acute severe cholecystitis.

OBJECTIVETo discuss the clinical therapeutic effects of electroacupuncture at Neimadian (Extra) and Neiguan (PC 6) on the analgesic effect of thoracic perioperative stage and its effect mechanism.

METHODSSixty cases of esophageal cancer with elective radical resection under general anesthesia were divided into an observation group and a control group according to the operation sequence, 30 cases in each one. In the control group, the general anesthesia was simply applied and sufentanil was administered for patient controlled intravenous analgesia (PCIA) after operation. In the observation group, on the basis of the scheme as the control group, the electroacupuncture was used at Neimadian (Extra) and Neiguan (PC 6) 30 min before anesthesia induction and after operation, with continuous wave, tolerable intensity, lasting for 30 min. Separately, before acupuncture (T1) and 2h (T2), 12h (T3), 24h (T4) and 48h (T5) after operation, the plasma β-endorphin (β-EP), 5-hydroxytryptamine (5-HT) and prostaglandin E(PGE) were determined. During operation, under the same state (from 50 to 60) of bispectrum of EEG (BIS), the intraoperative anesthetic dose was recorded. Using visual analogue scale (VAS), the pain degree was evaluated at T2, T3, T4 and T5 separately and the grade assessment of the therapeutic effects and safety were recorded at each time point.

RESULTS①The total dosage of sufentanil in the observation group was less than that in the control group[(1.83±0.56) mg vs (2.54±0.62) mg,<0.05]. ②VAS scores at T2, T3 and T4 in the patients of the observation group were all lower than those in the control group (all<0.05). ③The levels of plasma β-EP at T3, T4 and T5 in the observation group were increased significantly as compared with those in the control group (all<0.05) and the levels of plasma 5-HT and PGEat T2, T3 and T4 were reduced significantly as compared with those in the control group (all<0.05). ④ The excellent analgesia rates 2h、12h and 24h after operation in the observation group were better than those in the control group (all<0.05). ⑤The rate of the A grade safety in the observation group was higher than that in the control group (<0.05).

CONCLUSIONSElectroacupuncture at Neimadian (Extra) and Neiguan (PC 6) provides the safe and effective postoperative anesthesia of thoracic surgery and reduces the dosage of analgesics during the operation, which is possibly related to the increase of endogenous β-EP and the inhibition on the release of 5-HT and PGE.
