Objective To research of acupuncture for the perioperative analgesia and immune function of the breast cancer patients.Methods A total of 40 breast cancer patients who were carried out the radical operation was randomly (random number table method) divided into acupuncture combined drugs group and control group in our hospital during from 2015.1 to 2016.12. The patients in acupuncture combined drugs group was carried out acupuncture combined TCI anesthesia,and the patients in control group was carried out TCI anesthesia. The analgesic effect was evaluated by Visual analogue scales(VAS) in 2h, 6h, 12h, 24h and 48h after operation. The percentage of peripheral blood subgroups of T-lymphocytes (CD3+, CD4+, CD8+), natural killer cell (CD16+CD56+) and the ratio of CD4+/CD8+ was detected in 30 min before anesthesia,2h after beginning of operation,1d , 2d and 5d after operation.Results he VAS scores at 2 h (2.30 ± 1.12vs. 3.75 ± 1.06,t=2.378), 6 h (2.64 ± 1.23vs. 5.56 ± 1.41,t=3.289) and 12 h (3.49 ± 1.46vs. 4.99 ± 1.27,t=2.040) after operation of acupuncture combined drugs group wwere significantly lower than those of control group (P<0.05). The CD3+ (52.35％ ± 4.20％vs. 48.01％ ± 4.42％,t=2.127), CD4+ (27.81％ ± 2.72％vs. 24.96％ ± 2.60％,t=2.250), CD4+/CD8+ (1.12 ± 0.15vs. 1.01 ± 0.13,t=2.136) in acupuncture combined drugs group were significantly higher than those of the control group in 1d after operation (P<0.05). The CD16+ CD56+ 2 h (14.79％ ± 2.04％vs. 13.58％ ± 1.50％,t=2.852), 1 d (14.43％ ± 2.27％vs. 13.11％ ± 1.82％,t=2.933) in acupuncture combined drugs group were significantly higher han those of control group in 2h after beginning of operation and 1d after operation (P<0.05).Conclusions The analgesic effect of acupuncture could be applied to radical operation of breast cancer under general anesthesia. This method could protect the subgroups of T-lymphocytes and natural killer cell, and improve the immune function of breast cancer patients.

Objective:To discover the clinical features of nocturnal enuresis (NE) in adults and to detect factors that correlated with the symptom severity.Methods:This cross-sectional study recruited NE subjects from September 2017 through December 2020. All patients had experienced enuresis at least once per week and with a symptom duration of 3 months or longer. Followed by documentation of history and medical records, three-day bladder diary was adopted to assess their voiding pattern, and urodynamic parameters were obtained to evaluate lower urinary tract function.Results:A total of 106 NE patients (43 male and 63 female) were identified. There is no statistical difference regarding the average age (men: 57.8±15.6 vs. women: 56.1±14.0, P>0.05) and BMI (men: 23.9±3.4 vs. women: 23.3±4.3, P>0.05) between men and women. Comorbidities are extremely common in NE patients (n=85, 80.2%), with the incidence rate higher in men compared to women [88.4% (38/43)vs. 74.6% (47/63), P<0.05]. Hypertension (n=58, 54.7%), hyperlipemia (n=41, 38.7%), diabetes mellitus (n=38, 35.8%), coronary heart disease (n=22, 20.8%) were the most frequently reported conditions. On bladder diaries, subjects were frequently manifested nocturnal polyuria (NP, 47/106, 44.3%), reduced nocturnal bladder capacity (NBC, 74/106, 69.8%), or combination of both(33/106, 31.3%). Urodynamic studies suggested that the incidence of reduce bladder compliance, detrusor overactivity (DO), stress incontinence, bladder outlet obstruction(BOO), detrusor underactivity(DU)and detrusor hyperreflexia with impaired contractility(DHIC)was 27.4%(29/106), 39.6%(42/106), 17.9%(19/106), 9.4%(10/106), 25.5%(27/106)and 15.1%(16/106), respectively. Women were more likely to suffer from stress urinary incontinence [2.3%(1/43) men vs. 28.6% (18/63) women, P<0.01], while men were prone to have bladder outlet obstruction [ 23.3%(10/43) men vs. 0 women, P<0.01]. Correlation analysis demonstrated that obesity( r=0.63, P<0.01), systemic comorbidities( r=0.40, P<0.01), presence of NP( r=0.50, P<0.01) and NP+ NBC( r=0.47, P<0.01), post-void residual( r=0.53, P<0.01), reduced compliance( r=0.21, P=0.04), DU( r=0.28, P<0.01), stress incontinence( r=0.42, P<0.01)and DHIC ( r=0.35, P<0.01)are positively correlated with NE severity. Whereas, reduced Q max( r=-0.35, P<0.01), low capacity( r=0.21, P=0.03), and reduced bladder sensation( r=-0.21, P=0.03) correlate negatively with NE severity. Conclusions:The presence of NE is not only a sign of bladder dysfunction, but also an implication of obesity, systematic chronic diseases, urine production malfunctioning. Therefore, a thorough history regarding the lower urinary tract function and systemic comorbidities should be taken carefully, so that, an integrated and personalized treatment can be carried out.

C-C motif chemokine ligand 2(CCL2)and its receptor CCR2 are closely related to tumorigenesis and tumor progression.The CCL2/CCR2 signaling axis promotes tumor progression through multiple mechanisms:CCL2 binds to CCR2 on the surface of tumor cells,and thus promotes tumor growth/survival and metastasis;more importantly,CCL2 recruits a variety of immunosuppressive cells to aggregate in the tumor microenvironment,and inhibits the function and activity of immune cells,promoting tumor progression.The article reviews the CCL2/CCR2 signaling axis and its role in tumors and tumor microenvironment,with particular focus on the advances in clinical research on drugs targeting CCL2/CCR2 signaling axis,in order to gain an in-depth and overall understanding of the mechanism of action of CCL2/CCR2 axis in tumor progression and develop more effective anti-tumor immunotherapeutic agents.

Objective:To investigate the safety and efficacy of sacral neuromodulation(SNM)therapy for the treatment of lower urinary tract dysfunction(LUTD)in elderly patients.Methods:Clinical data of 91 elderly patients with LUTD from multiple medical institutions who received SNM during the period from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into four groups: the interstitial cystitis(IC)group(n=28), the neurogenic bladder(NB)group(n=36), the overactive bladder syndrome(OAB)group(n=13)and the idiopathic dysuria(ID)group(n=14). Different sets of evaluation parameters were used for different diseases.Patients’ baseline data and data in stage I(test phase)and stage Ⅱ(permanent SNM)were recorded, statistically analyzed and compared.Results:Ninety-one people underwent SNM treatment.Of them, 53 patients received permanent implants(stage Ⅱ), and the total conversion rate of stage I to stage Ⅱ was 58.2%(53/91). Patients receiving permanent implants(stage Ⅱ)had a preoperative period ranging from 3 months to 30 years, and were followed up for 2 to 58 months after treatment, with an average follow-up of 19.6 months.The improvement rates in stage I for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 35.4%, 31.6%, 33.7%, 32.6%, 49.2%, 43.2% and 13.2%, respectively.The improvement rates in stage Ⅱ for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 43.2%, 40.0%, 37.8%, 50.5%, 70.5%, 70.4% and 43.2%, respectively.Three adverse events occurred, including 1 case of recurrent symptoms, 1 case of moderate infection, and 1 case of electrical lead dislocation.Conclusions:Sacral nerve stimulation has definitive and consistent curative effects on LUTD in elderly people.The follow-up time should be extended to further study the safety of sacral nerve stimulation.

Objective:To analyze the clinicopathological features of de novo early colorectal cancer and to evaluate the efficacy of endoscopic treatment.Methods:Patients with de novo early colorectal cancer who underwent endoscopic resection in Beijing Friendship Hospital, Capital Medical University from June 2020 to May 2022 were enrolled. The baseline data, endoscopic manifestations, treatment methods, postoperative pathological results and prognosis of the patients were collected retrospectively.Results:A total of 33 patients with de novo early colorectal cancer were enrolled with the age of 62.67 ± 8.62 years, and the male to female ratio was 7.25∶1. The long diameter of lesions was 0.96 ± 0.36 cm. The lesion morphology was mainly superficial phenotype (type 0-Ⅱ), accounting for 72.7% (24/33). Endoscopic submucosal dissection (ESD) was performed in 29 cases and endoscopic mucosal resection (EMR) was performed in 4 cases. Postoperative pathology showed that 11 cases (33.3%) were well differentiated tubular adenocarcinoma, of which the superficial submucosal layer was invaded in 2 cases. Twenty cases (60.6%) were moderately differentiated tubular adenocarcinoma, of which the superficial submucosa layer was invaded in 5 cases and the deep submucosa layer in 15 cases. Two cases (6.1%) were moderately-poorly differentiated tubular adenocarcinoma, where the deep submucosa layer was invaded in both. There was significant correlation between the depth of invasion and the degree of differentiation ( P<0.001), and moderately and moderately-poorly differentiated lesions were more likely to invade the deep submucosa layer. The en bloc resection rate was 100.0% (33/33), the complete resection rate was 97.0% (32/33), and the curative resection rate was 42.4% (14/33). Among the 19 patients who did not achieve curative resection, 13 patients received supplementary surgical treatment. No tumor residue or lymph node metastasis was found in the postoperative pathology. All patients were followed up for 3-25 months, and no signs of local recurrence or metastasis were found. Conclusion:Most de novo early colorectal cancers are superficial phenotype under endoscopy. The pathology is mainly moderately differentiated tubular adenocarcinoma. Endoscopic resection of de novo early colorectal cancer shows encouraging short-term efficacy.

ObjectiveTo investigate the effect of Yunkang oral liquid on postpartum kidney deficiency in mice. MethodPostpartum mice were randomized into model and low-dose （6 mL·kg^-1）， medium-dose （9 mL·kg^-1）， and high-dose （12 mL·kg^-1） Yunkang oral liquid groups. The mouse model of postpartum kidney deficiency was established by sleep deprivation combined with forced swimming. Another 9 female ICR mice were selected as the normal control group. The mice were administrated with Yunkang oral liquid during the period of modeling. The levels of estradiol （E₂）， progesterone （P）， follicle-stimulating hormone （FSH）， and luteinizing hormone （LH） in the serum were measured by the enzyme-linked immunosorbent assay. The morphological changes of ovaries and uterus were observed by hematoxylin-eosin （HE） staining， and the expression of transforming growth factor （TGF）-β and Smad2/3 was determined by immunohistochemistry and Western blotting. ResultThe mice in the model group showed prolonged estrous cycle， reduced voluntary activity， dorsal temperature， grip strength， and bone strength， and whitening tongue coating. Compared with the model group， Yunkang oral liquid shortened the estrous cycle， increased the voluntary activity， dorsal temperature， grip strength， and bone strength， and alleviated the whitening of tongue coating. Moreover， it elevated the E₂ and P levels and lowered the FSH and LH levels in the serum， decreased ovarian follicular atresia rate， promoted uterine repair， and down-regulated the expression of TGF-β and Smad2/3 in the ovarian and uterine tissues. ConclusionYunkang oral liquid can ameliorate postpartum kidney deficiency in mice by regulating the TGF-β/Smads signaling pathway.
