Objective: To assess the dynamic changes of microcirculation at acupoints in patients with primary dysmenorrhea and cold congelation and blood stasis syndrome using laser speckle blood flow imaging. Methods: Patients with primary dysmenorrhea and cold coagulation and blood stasis syndrome (primary dysmenorrhea group, n=53) and healthy female college students(control group, n=57) who met the inclusion and exclusion criteria from October 2020 to July 2022 were enrolled at Hebei University of Chinese Medicine. On the premenstrual and first day of menstruation, a laser speckle blood flow imaging system was used to measure the microcirculation blood flow perfusion on the surface of acupoints related to the conception, thoroughfare, and governor vessels, and stomach, spleen, and bladder meridians in the abdomen and lumbosacral regions. The dynamic changes in microcirculation were calculated based on the difference in average blood flow perfusion at each acupoint before and after menstruation. Receiver operating curve (ROC) analysis was used to analyze the diagnostic efficacy of dynamic changes in microcirculation on the surface of each acupoint. The microcirculation sensitization rate of acupoints was calculated. Results: Compared with the control group, the dynamic changes in microcirculation at the following acupoints in the primary dysmenorrhea group were increased (P<0.05): conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]); left thoroughfare vessel (left Huangshu[KI16], left Zhongzhu[KI15], left Siman[KI14], left Qixue[KI13], left Dahe[KI12], left Henggu[KI11]); left stomach meridian (left Tianshu[ST25], left Wailing[ST26], left Qichong[ST30]); left spleen meridian (left Daheng[SP15], left Fujie[SP14]); right thoroughfare vessel (right Huangshu[KI16], right Zhongzhu[KI15], right Siman[KI14], right Qixue[KI13], right Dahe[KI12], right Henggu[KI11]); right stomach meridian (right Wailing[ST26], right Daju[ST27], right Shuidao[ST28], right Guilai[ST29], right Qichong[ST30]); and right spleen meridian (right Fujie[SP14]). The area under the ROC curve of conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]), thoroughfare vessel (right Siman[KI14], left Huangshu[KI16], right Qixue[KI13], right Zhongzhu[KI15], right Dahe[KI12], left Zhongzhu[KI15], left Siman[KI14], right Huangshu[KI16], left Qixue[KI13], right Henggu[KI11], left Henggu[KI11], left Dahe[KI12]); stomach meridian (left Tianshu[ST25], right Guilai[ST29], left Wailing[ST26], right Shuidao[ST28], right Daju[ST27], right Wailing[ST26], right Qichong[ST30], left Qichong[ST30]), and spleen meridian (left Daheng[SP15], left Fujie[SP14], right Fujie[SP14]) was 0.610-0.682 (P<0.05). Compared with the control group, the sensitization rate of some acupoints in the primary dysmenorrhea group increased (P<0.05). Conclusion With the onset of menstruation, the blood flow perfusion of some acupoints in the abdomen (thoroughfare, and conception vessels, and stomach and spleen meridians) of patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome increased, and the status of acupoints changed from a resting state to an active state. These acupoints are sensitive in patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome and have a certain diagnostic efficacy, providing a basis for further analyzing the efficacy and mechanism of acupuncture and moxibustion to treat primary dysmenorrhea with cold blood coagulation and blood stasis syndrome.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer (LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha (FAPα) expression in LNM-CRC cells. Gain- or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis (CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.

Objective We aimed to observe the differences in the effects of different acupuncture technique on the endometrium of mice with simple endometrial hyperplasia model and to explore the potential mechanisms. Methods According to the random number tables,32 female C57BL/6J mice were divided into a blank control group,a model group,a quick needle group and a retaining needle group,with 8 mice in each group. A mouse model of simple endometrial hyperplasia was established using bilateral ovariectomy combined with estrogen loading. In the quick needle group,mice were punctured at the bilateral for "Yinbai"(SP1) points and withdrawn immediately,with the treatmeat performed once every other day for a total of 12 times. In the retaining needle group,mice were punctured at the bilateral "Yinbai"(SP1) points and the needles were retained for 15 min each time,with the treatment also performed once every other day for a total of 12 times. After the intervention,samples were collected. HE staining was used to observe morphological changes in the mouse uterine tissue;ELISA was used to detect serum estradiol level;flow cytometry was used to detect the ratio of M1 and M2 macrophages(M1/M2) and immunohistochemical method was used to measure the expression of CD86 and CD206 in uterine tissue;and Western blotting was used to detect the expression of interleukin-13 (IL-13) and interferon-γ(IFN-γ) in uterine tissue. Results The endometrium of mice in the model group showed simple hyperplasia. Compared with the blank control group,the endometrium of the model group was thickened (P<0.01);the level of estradiol in the serum was increased (P<0.01);M1/M2 in uterine tissues was decreased (P<0.01),the expression of CD86 was decreased (P<0.01),and the positive expression of CD206 was increased (P<0.01);and the level of IFN-γ protein expression in uterine tissues was decreased (P<0.01),and the expression of IL-13 protein was increased (P<0.01). Compared with the model group,the endometrial thicknesses of the quick needle group and the retaining needle group were reduced (P<0.05),the levels of estradiol in serum were reduced (P<0.05),M1/M2 in uterine tissues increased (P<0.01),and the reduction of CD206 positive expression,and IL-13 protein expression reduced (P<0.01);the level of CD86 positive expression,IFN-γ protein expression increased (P<0.01). Compared with the quick needle group,IL-13 protein expression increased in the retaining needle group (P<0.01).Conclusion Both quick needle and retaining needle may be through the regulation of the expression of IFN-γ and IL-13,thus prompting the polarization of macrophages from M2 to M1 type,inhibiting the pro-cell proliferative ability and tissue repair ability of M2 type macrophages,thus reducing the degree of endometrial hyperplasia,and the quick needle group was superior to the retaining needle group in regulating the expression of IL-13.

Objective:To evaluate the clinical efficacy of acupuncture in the treatment of anxiety state in patients with primary insomnia(PI). Methods:Randomized controlled trials of acupuncture treatment for PI patients with an anxiety state in Web of Science,Cochrane Library,PubMed,Excerpta Medica Database(EMBASE),China National Knowledge Infrastructure(CNKI),Wanfang Data Knowledge Service Platform(Wanfang),and Chongqing VIP Database(VIP)were retrieved by computer.The retrieval time was from each database's inception to December 30,2022.Data extraction and evaluation were performed for the included studies.The Cochrane risk of bias assessment tool was used to assess the risk of bias in each article.Meta-analysis of valid data was performed using the RevMan 5.4 software.If the outcome indicator was a categorical variable,relative risk(RR)was used as the effect size.If it was a continuous variable,mean difference(MD)was used to calculate the effect size.Each effect size was expressed as a 95%confidence interval(CI).P<0.05 was considered to indicate a statistically significant difference. Results:A total of 18 studies were included,comprising a total of 1198 patients.The findings of the meta-analysis showed that electroacupuncture had a significant advantage in improving the Hamilton anxiety scale(HAMA)score than benzodiazepines[MD=-1.61,95%CI(-2.17,-1.06),P<0.001].Acupuncture was superior to sham acupuncture[MD=-14.90,95%CI(-20.39,-9.41),P<0.001]and benzodiazepines[MD=-3.39,95%CI(-4.67,-2.12),P<0.001]in reducing the self-rating anxiety scale(SAS)score.Acupuncture was superior to sham acupuncture in reducing the insomnia severity index(ISI)score[MD=-5.61,95%CI(-6.63,-4.89),P<0.001].Acupuncture was superior to benzodiazepines[MD=0.84,95%CI(-1.42,-0.25),P=0.005]and sham acupuncture[MD=-8.39,95%CI(-8.39,-7.86),P<0.001]in improving the Pittsburgh sleep quality index(PSQI)score.Acupuncture had a better effective rate than benzodiazepines[RR=1.16,95%CI(1.08,1.25),P<0.001]and sham acupuncture[RR=8.94,95%CI(4.63,17.25),P<0.001]in treating PI. Conclusion:Acupuncture or electroacupuncture has certain therapeutic advantages over benzodiazepines and sham acupuncture in the treatment of anxiety in PI patients.However,more high-quality randomized controlled trials are needed for further verification.

BACKGROUND: The KangDuo-Surgical Robot-01 (KD-SR-01) system is a new surgical robot recently developed in China. The aim of this study was to present our single-center experience and mid-term outcomes of urological procedures using the KD-SR-01 system. METHODS: From August 2020 to April 2023, consecutive urologic procedures were performed at Peking University First Hospital using the KD-SR-01 system. The clinical features, perioperative data, and follow-up outcomes were prospectively collected and analyzed. RESULTS: A total of 110 consecutive patients were recruited. Among these patients, 28 underwent partial nephrectomy (PN), 41 underwent urinary tract reconstruction (26 underwent pyeloplasty, 3 underwent ureteral reconstruction and 12 underwent ureterovesical reimplantation [UR]), and 41 underwent radical prostatectomy (RP). The median operative time for PN was 112.5 min, 157.0 min for pyeloplasty, 151.0 min for ureteral reconstruction, 142.5 min for UR, and 138.0 min for RP. The median intraoperative blood loss was 10 mL for PN, 10 mL for pyeloplasty, 30 mL for ureteral reconstruction, 20 mL for UR, and 50 mL for RP. All procedures were successfully completed without conversion, and there were no major complications in any patient. The median warm ischemia time of PN was 17.3 min, and positive surgical margin was not noted in any patient. The overall positive surgical margin rate of RP was 39% (16/41), and no biochemical recurrence was observed in any RP patient during the median follow-up of 11.0 months. The surgical success rates of pyeloplasty and UR were 96% (25/26) and 92% (11/12) during the median follow-up of 29.5 months and 11.5 months, respectively. CONCLUSION The KD-SR-01 system appears feasible, safe, and effective for most urological procedures, based on our single-center experience.

Synovial sarcoma is a soft tissue malignancy of unknown origin which usually occurs around the joints of the extremities, but rarely detected in the kidneys. A case of primary synovial sarcoma of the kidney was reported, which was preoperatively diagnosed as a malignant tumor of the right kidney for intermittent gross hematuria. After the laparoscopic radical nephrectomy, primary renal synovial sarcoma was confirmed by pathological examination. The patient refused further treatment, and there was no recurrence or metastasis during the 13 months of follow-up.

Objective:To evaluate the efficacy of percutaneous curved kyphoplasty (PCKP) for the treatment of osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective cohort study was conducted to analyze the clinical data of 70 patients with OVCF admitted to Third People′s Hospital of Datong from May 2020 to December 2021, including 32 males and 38 females, aged 60-89 years [(73.0±8.7)years]. The patients were treated with PCKP (PCKP group, n=20) or percutaneous vertebroplasty (PVP) (PVP group, n=50). The operation time, intraoperative blood loss, length of hospital stay, excellent rate of bone cement distribution at postoperative 1 day, and leakage rate of bone cement were compared between the two groups. In addition, anterior height ratio of the injured vertebrae, upper and lower Cobb angle, visual analogue scale (VAS), and Oswestry dysfunction index (ODI) were measured preoperatively and at postoperative 24 hours and 3 months. Results:All patients were followed up for 3-4 months [(3.0±0.6)months]. There were no significant differences in the operation time, intraoperative blood loss, and length of hospital stay between the two groups (all P>0.05). At postoperative 1 day, the excellent rate of bone cement distribution was 100% in PCKP group (excellent in 13 patients, good in seven, poor in zero), significantly higher than 82% in PVP group (excellent 21 patients, good in 20, and poor in nine). The leakage rate of bone cement was 0%(0/20) in PCKP group, lower than 20% (10/50) in PVP group ( P<0.05). There were no significant differences in the anterior height ratio of injured vertebrae, upper Cobb angle, lower Cobb angle, VAS and ODI between the two groups before operation (all P>0.05). At postoperative 1 day, PCKP group showed significantly higher anterior height ratio of injured vertebrae and significantly lower upper Cobb angle, lower Cobb angle, VAS, and ODI than those in PVP group ( P<0.05 or 0.01). At postoperative 3 months, PCKP group still showed significantly higher anterior height ratio of injured vertebrae and significantly lower upper Cobb angle and lower Cobb angle than those in PVP group ( P<0.05 or 0.01), but there was no significant difference in VAS and ODI between the two groups (all P>0.05). In PCKP group, the anterior height ratio of the injured vertebrae was significantly increased and the upper Cobb angle, lower Cobb angle, VAS, and ODI index were significantly decreased at postoperative 1 day and 3 months when compared with those before operation (all P<0.05). In PVP group, there were no significant changes in the anterior height ratio of the injured vertebrae, upper Cobb angle, and lower Cobb angle at postoperative 1 day and 3 months when compared with those before operation (all P>0.05), but the VAS and ODI were significantly lowered at postoperative 1 day and 3 months when compared with those before operation (all P<0.05). Conclusion:Compared with PVP, PCKP has better diffusion effect of bone cement in the injured vertebrae and lower incidence of bone cement leakage in the treatment of OVCF, which can effectively promote height recovery of the injured vertebrae, relieve the pain early, and improve spinal function.

Objective:To investigate the small and dense low density lipoprotein cholesterol (sdLDL-C) level, ratios of sdLDL-C/low density lipoprotein cholesterol (LDL-C), sdLDL-C/high density lipoprotein cholesterol (HDL-C) and sdLDL-C/apolipoprotein B (apoB), and their correlation with lipid components in healthy adults.Methods:A total of 1 151 healthy adults, who underwent physical examination in Beijing Anzhen Hospital Affiliated to Capital Medical University from September to December 2020 (557 men and 594 women), were included in this study. They were divided into five age groups: 18-29 years old ( n=247), 30-44 years old ( n=269), 45-59 years old ( n=225), 60-74 years old ( n=207) and 75-90 years old ( n=203) according to the age classification standard of the United Nations World Health Organization in 2018. The levels of total cholesterol (TC), triglyceride (TG), HDL-C, LDL-C, sdLDL-C, apoA1 and apoB were measured, and the distribution of sdLDL-C, sdLDL-C/LDL-C, sdLDL-C/HDL-C and sdLDL-C/apoB in different sex and age groups were analyzed. Pearson/Spearman correlation was used to analyze the correlation between the above four indexes and other blood lipid components. Results:SdLDL-C, sdLDL-C/LDL-C, sdLDL-C/HDL-C and sdLDL-C/apoB were higher in male group ([0.56±0.23] mmol/L, 0.24±0.07, 0.49±0.22, 0.27±0.07) than those in female group ([0.48±0.18] mmol/L, 0.20±0.06, 0.36±0.17, 0.23±0.07) (all P<0.01). SdLDL-C, sdLDL-C/LDL-C, sdLDL-C/HDL-C and sdLDL-C/apoB were different among different age groups of male and female participants (all P<0.001). SdLDL-C level was significantly higher in males than in females among 18-29 years old group, 30-44 years old group, 45-59 years old group (all P<0.05). SdLDL-C, sdLDL-C/LDL-C, sdLDL-C/HDL-C and sdLDL-C/apoB were higher in males of 18-29 years old group, 30-44 years old group, 45-59 years old group and 60-74 years old group than in females of corresponding age groups (all P<0.05). The level of sdLDL-C of all participants was positively correlated with TC, TG, LDL-C, apoB, non-HDL-C and remnant cholesterol ( r＝0.50, 0.45, 0.67, 0.68, 0.61, 0.11, all P<0.01), and negatively correlated with HDL-C and apoA1 ( r＝-0.17 and -0.10, P<0.01). Conclusions:The levels of sdLDL-C, sdLDL-C/LDL-C, sdLDL-C/HDL-C and sdLDL-C/apoB in healthy adults are different in healthy adults of different ages and sex. There is a high correlation between sdLDL-C and apoB.

Objective:To investigate and establish the related factors of non-invasive score model for prediction of non-alcoholic fatty liver disease in chronic hepatitis B patients with normal or mildly elevated alanine aminotransferase (ALT).Methods:A total of 128 cases with chronic hepatitis B who had undergone liver biopsy were included. According to the presence or absence of hepatocyte steatosis on the pathological results of liver biopsy, they were divided into a fatty infiltration and a non-fatty infiltration group. Patients' demographic characteristics, laboratory test indexes, and pathological test results were collected. Univariate and multivariate logistic regression analysis combined with clinical screening variables were used to establish a predictive model. The prediction efficiency of the new model was evaluated by the receiver operating curve, and the difference between the accuracy of the new model and ultrasound in the diagnosis of fatty liver was compared by Delong's-test.Result:Multivariate regression analysis showed that serum triglyceride, serum uric acid and platelets were highly correlated with intrahepatic steatosis ( P<0.05). The regression equation triglyceride-uric acid-platelet (TUP)-1=-8.195+0.011×uric acid+1.439×triglyceride+0.012×platelet count was established by combining the above variables. Tthe equation TUP-2=-7.527+0.010×uric acid+1.309×triglyceride+0.012×platelet count+1.397×fatty liver (ultrasound) was established (yes=1; no=0) after incorporating the results of abdominal ultrasound. The diagnostic value of TUP-1 and TUP-2 models for fatty liver was better than that of ultrasound alone and there was no statistically significant difference in diagnostic value between TUP-1 and TUP-2 models ( Z=1.453, P=0.146). Conclusion:Compared with abdominal ultrasonography alone, the new model is more effective in diagnosing fatty liver and has good application value.
