As a traditional Chinese medicinal herb for pacifying the liver and extinguishing wind， Gastrodiae Rhizoma contains main active ingredients such as gastrodin， gastrodia polysaccharides and gastrodigenin. It exerts the effects of extinguishing wind and relieving convulsions， calming liver yang， dispelling wind and unblocking collaterals， which is highly consistent with the traditional Chinese medicine pathogenesis of hypertension. This paper systematically reviews the pharmacological effects and molecular mechanisms of active ingredients of Gastrodiae Rhizoma， herb pair compatibility， and classic prescriptions in hypertension. It is found that Gastrodiae Rhizoma and its active ingredients can collaboratively exert antihypertensive effects by regulating hemodynamics， oxidative stress， inflammatory response and other pathways， alleviate hypertensive vascular injury， and ameliorate damage to target organs including the heart， brain and kidney induced by hypertension. Compatibility of Gastrodiae Rhizoma with medicinal materials such as Uncaria， Chuanxiong， and Danshen produces remarkable synergistic efficacy against hypertension. Classic prescriptions containing Gastrodiae Rhizoma represented by Tianma gouteng decoction and Banxia baizhu tianma decoction can inhibit inflammation， resist oxidation， and protect vascular endothelium， so as to ameliorate hypertensive vascular injury and lower blood pressure.

Objective:To study whether the "combination of medical care and pension" service model can effectively control the development of chronic disease in the elderly and reduce the direct economic burden caused by the disease.Methods:A total of 180 elderly participants who received the "combination of medical care and pension" service model for chronic disease management in Chongqing, China were investigated and analyzed statistically. Epidata 2.0 was used for data entry, SPSS 20.0 was used for data analysis, and paired sample t test was used for comparison between groups. Results:After 12 months of chronic disease management, hospitalization events and expenses of the elderly were reduced, among which the number of hospitalization was reduced by 0.24 timed on average, the length of hospitalization was reduced by 10.41 days on average, and the hospitalization expenses were reduced by 11 144 yuan on average. The direct economic burden due to chronic diseases was reduced by approximately 8 844.5 yuan, accounting for 33.8% of the average cost of hospitalization for the elderly without the application of the model.Conclusion:The chronic disease of the elderly is well controlled by chronic disease management through the "combination of medical care and pension" service model.

Sepsis is one of the critical illnesses caused by burns, trauma, shock, infection, and so on. In patients with sepsis, vascular permeability is prone to develop through various pathophysiological mechanisms and thus could result in accumulation of tissue fluid, insufficient intravascular fluid, and finally cause septic shock and multiple organ dysfunction syndrome. Recent studies have shown that various factors and mediators involved in the regulation of vascular permeability in sepsis are expected to become targets for clinical treatment of sepsis. In this paper, we have reviewed the research advances on some molecules which are significantly associated with vascular permeability in sepsis, such as vascular endothelial growth factor, angiopoietin, sphingosine-1-phosphate, heparin-binding protein, and Slit2.

Objective: To evaluate the clinical feasibility and advantages of ultrasound guided mammotome biopsy for micro-calcifications visible in mammography. Methods: A total of 12 patients with mammography-revealed micro-calcifications examined by ultrasound guided vacuum-assisted biopsy in our hospital from Jun. 2017 to Dec. 2018 were enrolled in this study and their medical records data were analyzed. Results: All 12 patients had accepted pre-biopsy ultrasound localization and all micro-calcifications were successfully excised. Among 12 cases, 4 were revealed as benign breast diseases and 8 were diagnosed as breast cancer. Conclusions Ultrasound guided mammotome biopsy is found to be an alternative method to stereotactic biopsy in patients with US-detectable micro-calcifications, and re-scan ultrasonography focusing on the specific microcalcification area may be helpful for improving the ultrasound detection rate of micro-calcifications.

Objective To evaluate the efficacy and safety of tip-flexible ureterorenoscope (tf-URS) with holmium laser for one-stage management of parapelvic cyst.Methods The clinical data of 26 patients treated with tf-URS incision and drainage using holmium laser from February 2016 to August 2018 were reviewed.The study were including 15 male and 11 female patients,ranging from 32 to 68 years old,with an average of 53.5 years old.There were 24 cases of unilateral single renal parapelvic cyst and 2 cases of bilateral single renal parapelvic cyst.There were 4 cases in 26 cases with unilateral single renal parapelvic cyst and contralateral single renal cyst,2 cases with unilateral single renal parapelvic cyst and ipsilateral kidney of stones.The diameter of parapelvic cyst was 3.4-5.6 cm,average 4.8 cm.All patients had undergone holmium laser endo-decortication of parapelvic cyst by tf-URS.With general anesthesia,tf-URS accessed pelvis retrogradely and decorticated parapelvic cyst with 200 μm Holium laser to drainage the cyst to pelvis.If the tf-URS was not placed successfully for the first time,Double-J tubes were retained for 1-2 weeks before treatment.The operative time,hospitalization time,blood loss,postoperative complications and clinical symptoms were collected and analyzed.Results The one-time access success rate of insertion of ff-URS was 88.5％ (23/26).All operations were successful without severe complications.The average time of operation was 17.2 min,ranging from 11 to 25 min.In 3-30 months follow-up,the cysts disappeared in 22 patients and reduced by more than one half in 1 patients.Flank pain relieved in 19 patients.Conclusions Holmium laser endo-decortication of parapelvic cyst by tf-URS could be a simple,minimally invasive,safe and effective method for parapelvic cyst,which is worthy of further promotion and application in clinical practice.

Objective: To investigate the diagnosis and treatment for enterocutaneous fistula (ECF) in China, and to explore the prognostic factors of ECF. Methods: A multi-center cross-sectional study was conducted based on the Registration System of Chinese Gastrointestinal Fistula and Intra-Abdominal Infections to collect the clinical data of ECF patients from 54 medical centers in 22 provinces/municipalities from January 1, 2018 to December 31, 2018. The clinical data included patient gender, age, length of hospital stay, intensive care unit (ICU) admission, underlying diseases, primary diseases, direct causes of ECF, location and type of ECF, complications, treatment and outcomes. All medical records were carefully filled in by the attending physicians, and then re-examined by more than two specialists. The diagnosis of ECF was based on the clinical manifestations, laboratory/imaging findings and intraoperative exploration. Results: A total of 1521 patients with ECF were enrolled, including 1099 males and 422 females, with a median age of 55 years. The top three primary diseases of ECF were malignant tumors in 626 cases (41.2%, including 540 gastrointestinal tumors, accounting for 86.3% of malignant tumors), gastrointestinal ulcers and perforations in 202 cases (13.3%), and trauma in 157 cases (10.3%). The direct causes of ECF were mainly surgical operation in 1194 cases (78.5%), followed by trauma in 156 (10.3%), spontaneous fistula due to Crohn′s disease in 92 (6.0%), radiation intestinal injury in 41 (2.7%), severe pancreatitis in 20 (1.3%), endoscopic treatment in 13 (0.9%) and 5 cases (0.3%) of unknown reasons. All the patients were divided into three groups: 1350 cases (88.7%) with simple ECF, 150 (9.9%) with multiple ECF, and 21 (1.4%) with combined internal fistula. Among the patients with simple ECF, 438 cases (28.8%) were jejuno-ileal fistula, 313 (20.6%) colon fistula, 170 (11.2%) rectal fistula, 111 (7.3%) duodenal fistula, 76 (5.0%) ileocecal fistula, 65 (4.3%) ileocolic anastomotic fistula, 55 (3.6%) duodenal stump fistula, 36 (2.4%) gastrointestinal anastomotic fistula, 36 (2.4%) esophagogastric/esophagojejunal anastomotic fistula, 29 (1.9%) gastric fistula and 21 (1.4%) cholangiopancreatiointestinal. Among all the simple ECF patients, 991 were tubular fistula and 359 were labial fistula. A total of 1146 patients finished the treatment, of whom 1061 (92.6%) were healed (586 by surgery and 475 self-healing) and 85 (7.4%) died. A total of 1043 patients (91.0%) received nutritional support therapy, and 77 (6.7%) received fistuloclysis. Infectious source control procedures were applied to 1042 patients, including 711 (62.0%) with active lavage and drainage and 331 (28.9%) with passive drainage. Among them, 841 patients (73.4%) underwent minimally invasive procedures of infectious source control (replacement of drainage tube through sinus tract, puncture drainage, etc.), 201 (17.5%) underwent laparotomy drainage, while 104 (9.1%) did not undergo any drainage measures. A total of 610 patients (53.2%) received definitive operation, 24 patients died within postoperative 30-day with mortality of 3.9% (24/610), 69 (11.3%) developed surgical site infection (SSI), and 24 (3.9%) had a relapse of fistula. The highest cure rate was achieved in ileocecal fistula (100%), followed by rectal fistula (96.2%, 128/133) and duodenal stump fistula (95.7%,44/46). The highest mortality was found in combined internal fistula (3/12) and no death in ileocecal fistula. Univariate prognostic analysis showed that primary diseases as Crohn′s disease (χ²=6.570, P=0.010) and appendicitis/appendiceal abscess (P=0.012), intestinal fistula combining with internal fistula (χ²=5.460, P=0.019), multiple ECF (χ²=7.135, P=0.008), esophagogastric / esophagojejunal anastomotic fistula (χ²=9.501, P=0.002), ECF at ileocecal junction (P=0.012), non-drainage/passive drainage before the diagnosis of intestinal fistula (χ²=9.688, P=0.008), non-drainage/passive drainage after the diagnosis of intestinal fistula (χ²=9.711, P=0.008), complicating with multiple organ dysfunction syndrome (MODS) (χ²=179.699, P<0.001), sepsis (χ²=211.851, P<0.001), hemorrhage (χ²=85.300, P<0.001), pulmonary infection (χ²=60.096, P<0.001), catheter-associated infection (χ²=10.617, P=0.001) and malnutrition (χ²=21.199, P<0.001) were associated with mortality. Multivariate prognostic analysis cofirmed that sepsis (OR=7.103, 95%CI:3.694-13.657, P<0.001), complicating with MODS (OR=5.018, 95%CI:2.170-11.604, P<0.001), and hemorrhage (OR=4.703, 95%CI: 2.300-9.618, P<0.001) were independent risk factors of the death for ECF patients. Meanwhile, active lavage and drainage after the definite ECF diagnosis was the protective factor (OR=0.223, 95%CI: 0.067-0.745, P=0.015). Conclusions The overall mortality of ECF is still high. Surgical operation is the most common cause of ECF. Complications e.g. sepsis, MODS, hemorrhage, and catheter-associated infection, are the main causes of death. Active lavage and drainage is important to improve the prognosis of ECF.

Objective: To investigate the safety and efficacy of haploidentical hematopoietic stem cell transplantation with different intensity conditioning regimen in the treatment of childhood aplastic anemia (AA) . Methods: Thirty-seven AA patients who underwent haploidentical transplantation in BaYi Children's Hospital Affiliated to PLA Army General Hospital from January 2013 to January 2017 were enrolled. According to the dosage of conditioning regimen, 34 patients excluding 3 other conditioning regimens were divided into high-dosage group (regimen 2, 22 cases) and low-dosage group (regimen 3, 12 cases). The data of Engraftment, graft-vs-host disease (GVHD), hematopoietic reconstitution, relapse, infection, overall survival (OS) were analyzed. The comparison between the two groups was tested by χ² test. Results: A total of 35 of 37 patients achieved primary engraftment; 2 cases died of regimen-related toxicity and severe infection before the infusing of the grafts. The activation rate of CMV and EBV was 60% (21/35) . Post-transplant lymphocyte disease (PTLD) of lung occurred in one case. The cumulative incidences of acute GVHD grade Ⅰ-Ⅳ and chronic GVHD were 29% (10/35) and 34% (12/35) respectively and the incidence of extensive chronic GVHD was 6% (2/35) . The median follow-up time was 18.8 (2.9-44.1) months, the OS was 92% (34/37) .All survived patients were no longer dependent on blood transfusion and none of them had recurrence. Comparing the rates of overall survival(86%(19/22) vs.100%(12/12)) and rates of chronic GVHD(40%(8/20) vs. 17%(2/12)) in regimen 2 and regimen 3 group, there were no significant difference (χ²=1.742, 1.841, all P>0.05) . Significant difference was found at the incidence of Ⅰ-Ⅳ acute GVHD (10% (2/20) vs. 50% (6/12) ,χ²=6.200, P=0.013). Conclusions Haploidentical hematopoietic stem cell transplantation is effective and safe. It is suitable for patients who are not eligible for matched donor transplantation. Application of reduced dose preconditioning in haploid transplantation is worth exploring.

Objective To evaluate the safety and efficacy of transurethral frontfiring photoselective vaporesection for the treatment of cystitis glandularis,by comparing with the transurethral bipolar plasmakinetic resection.Methods From January 2014 to July 2016,41 patients with pathologically diagnosed cystitis glandularis in our hospital,were divided into two groups,including 22 cases underwent transurethral frontfiring photoselective vaporesection(the observation group),and the other 19 cases underwent transurethral bipolar plasmakinetic resection(the control group).All patients were regularly treated with postoperative intravesical instillation chemotherapy with pirarubicin.The clinical data of two groups were statistically analyzed to compare the differences of the safety and efficacy.Results All the surgeries were performed successfully.There were no statistical significances in perioperative data,the operation time,the decreased concentration of hemoglobin(Hb)and Na+,operative related complications, indwelling catheter duration and hospitalization duration between the two groups.The first-time cure rate and the effective rate of transurethral frontfiring photoselective vaporesection showed significantly better than those of transurethral bipolar plasmakinetic resection(P<0.05 for each).Conclusion Comparing the traditional transurethral bipolar plasmakinetic resection for the treatment of cystitis glandularis,tansurethral frontfiring photoselective vaporesection with postoperative intravesical instillation chemotherapy with pirarubicin,is a safer,simpler,and more effective method,which could be a new optional method in the conditional hospitals,deserving the worthy of clinical popularization.
