ABSTRACT
Objective:To analyze the medication law of Traditional Chinese Medicine (TCM) fumigation and washing to promote postoperative healing of hemorrhoids by data mining technology.Methods:The clinical literature about TCM fumigation and washing to promote postoperative healing of hemorrhoids was retrieved from the databases of CNKI, Wanfang, VIP, PubMed from the establishment of the databases to March 10, 2022. The frequency efficacy attributes, core medicinal pairs and core prescriptions of TCM were analyzed by using the Ancient and Modern Medical Records Cloud Platform (V2.3.5).Results:A total of 299 articles were included, involving 200 kinds of Chinese materia medica. The drugs used at high frequency ≥40 were Sophorae Flavescentis Radix, Phellodendri Chinensis Cortex, Natrii Sulfas, Galla Chinensis and Rhei Radix et Rhizoma and so on. The main efficacy was to clear heat and reduce dampness; cold, warm and slightly cold were the main medicinal properties, and the tastes were mainly bitter, pungent, sweet and sour, and most of the drugs return to the liver meridian, stomach meridian, heart meridian, large intestine meridian and so on. A total of 22 rules were obtained by correlation analysis. Five groups of drugs were obtained by clustering analysis. The core prescription drugs obtained by complex network analysis included Sophorae Flavescentis Radix, Phellodendri Chinensis Cortex, Natrii Sulfas, Galla Chinensis, Rhei Radix et Rhizoma, Taraxaci Herba, Borneolum Syntheticum, Sanguisorbae Radix, Atractylodis Rhizoma, Carthami Flos, Scutellariae Radix, Olibanum, Myrrha, and Lonicerae Japonicae Flos. Conclusion:TCM fumigation and washing can promote the postoperative healing of hemorrhoids mainly by clearing heat and reducing dampness and detoxification, as well as promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, restraining sore and generating muscle.
ABSTRACT
Objective:To analyze the relationship between the high sensitivity C-reactive protein (hs-CRP) and anxiety levels in patients hospitalized with cardiovascular-related diseases and hypertension.Methods:A total of 221 patients hospitalized with cardiovascular-related diseases in the Fuwai Hospital were selected by a voluntary sampling method from September to December 2021. Participants were divided into hypertensive and non-hypertensive groups ( n=119 and n=102) based on the diagnosis of hypertension in their inpatient medical records. Anxiety levels were assessed using the Zung Self-Rating Anxiety Scale, and the levels of serum hs-CRP were estimated by automatic immunoanalyzer. Multivariate logistic regression was used to analyze the relationship between hs-CRP and anxiety. Results:In the hypertensive group, the risk of anxiety in patients with abnormal hs-CRP (>3 mg/L) was 4.239 times (95% CI: 1.569-11.748, P=0.005) higher than those in normal hs-CRP (≤3 mg/L). In turn, compared with patients without anxiety, those with anxiety had 3.878 times greater probability of experiencing abnormal hs-CRP (95% CI: 1.495-10.062, P=0.005), while those with mild anxiety and moderate to severe anxiety had 4.525 times (95% CI: 1.392-14.714, P=0.012) and 3.286 times (95% CI: 0.911-11.357, P=0.070) greater odds of experiencing abnormal hs-CRP, respectively. No similar significant association was seen in the non-hypertensive group. Conclusion:There is an interrelationship between elevated hs-CRP and anxiety in hospitalized patients with cardiovascular-related diseases and hypertension.

Objective@#To evaluate efficacy and safety of retrograde intrarenal stone surgery for treatment of upper urinary calculi.@*Methods@#The clinical data of 640 patients with upper urinary tract calculi treated by retrograde intrarenal stone surgery (RIRS) in Renmin Hospital of Wuhan University from April 2016 to January 2019 were retrospectively analyzed. There were 424 males and 216 females. The awerage age was (46.2±12.8) years old, ranging 18 to 76 years old. The maximum diameter of the stone is (1.4±0.7) cm, ranging 0.6-3.2 cm. There were 126 cases with inferior calculi and 514 cases with non-lurgical calculi. There were 196 cases with unilateral ureteral calculi, 118 unilateral ureteral calculi cases with renal calculi, 236 cases with unilateral renal stones, and 90 cases with double kidney stones. 104 cases were placed with double J tube before operation and 496 cases were not placed before operation. There were 8 cases of horseshoe kidney, 30 cases of isolated kidney with renal insufficiency, 4 cases of pelvic ectopic kidney with dysplasia, 6 cases of congenital ureteral malformation and 2 cases of sponge kidney. Preoperative average hemoglobin was (133.2±5.6)g/L, ranging 126-188 g/L.And average serum creatinine was (84.4±12.2)μmol/L, ranging 74-242μmol/L before operation. All patients were treated with general anesthesia under the lithotomy position. The ureteroscopy combined with holmium laser lithotripsy was performed.The 200μm fiber was used, which the parameters were set as 12-45 W(0.5-1.5 J/10-30 Hz). The stone baskets were used to take stones according to actual conditions. The operation was performed by doctors of the same qualifications.@*Results@#All patients underwent successful operation. The mean operation time was (45.6±14.6)min. The average postoperative hospitalization was (4.8±1.5)d. The postoperative serious complication rate was 0.9%, including(2 cases of sepsis and 1 case of subcapsular hematoma. Of the 640 patients, 596 were admitted to the hospital for a double J tube and 44 were lost of follow-up. 552 patients met the stone removal criteria, 44 patients did not meet the stone removal criteria for other treatments, such as extracorporeal shock wave lithotripsy, ureteroscopy or observed regularly. The stone-free rate (SFR) was 92.6% (552/596) after 1-3 months. On the first postoperative day, serum creatinine was (76.0±10.6)(58-156) μmol/L, and postoperative hemoglobin was (126.4±9. 6)(120-176) g/L. There was no significant difference in preoperative and postoperative hemoglobin (t=2.02, P=0.064). Preoperative and postoperative creatinine (t=64.76, P<0.05) was statistically significant. Meanwhile, the stone size (χ2=29.569, P<0.05) and position (χ2=44.949, P<0.05) versus SFR the impact was statistically significant. Multivariate regression analysis showed that stone size was not an independent risk factor for stone clearance (P=0.639). The stone position was an independent risk factor for stone clearance (P=0.013).@*Conclusions@#RIRS is a reliable treatment for small and medium calculi patients of the upper urinary tract. The curative effect of stone removal is clear, the complications are few, the safety is high. However, there are certain limitations to the efficacy in the treatment of large stones and lower calculi. Lower calculi is the independent risk factor for the treatment of efficacy.

ABSTRACT
Objective To investigate the regulatory actions of Intestines-unblocking, Turbid-purging Recipe (ITR) on colonic 5-hydroxytryptamine (5-HT) and its receptor 5-hydroxytryptamine 3 (5-HT3) in rats with constipation-dominant irritable bowel syndrome (IBS-C), and to explore the therapeutic mechanism of ITR in treating IBS-C. Methods Forty-two male SD rats were randomly divided into 6 groups, namely normal group, model group, western medicine group, high-, middle- and low-dose Chinese medicine groups, 7 rats in each group. IBS-C rat model was established by intragastric administration of ice water. After establishment of the model, western medicine group was given intragastric administration of Cisapride Tablets (at the dosage of 3.6 mg·kg-1·d-1), Chinese medicine groups were given intragastric administration of various dosages of ITR granules (18.5, 9.25, 4.625 g·kg-1·d-1 respectively) , and the model group was given intragastric administration of normal saline, the treatment lasting 14 d. The rats in various groups were given normal feeding and drinking. After treatment, HE staining method was used to observe pathological changes in the intestinal tissue, immunohistochemistry method was used to observe the expression levels of intestinal 5-HT and 5-HT3 receptor. Results Compared with the normal group, the expression level of rat intestinal 5-HT was increased (P < 0.05) and that of 5-HT3 receptor was decreased (P < 0.05) in the model group and the medication groups. Compared with the model group, 5-HT expression level was decreased significantly (P<0.05) and 5-HT3 receptor expression level was increased (P < 0.05) in the medication groups, and the improvement of the middle-dose Chinese medicine group was more obvious (P < 0.05). Conclusion ITR has therapeutic efficacy for IBS-C rats through lowering 5-HT expression and increasing 5-HT3 receptor expression, which results into the improvement of intestinal sensitivity and abnormal dynamic of the rats.
