Objective To discuss the feasibility of percutaneous nephrolithotomy (PCNL) for treating upper urinary calculi under local anesthesia.Methods One thousand three hundred and sixty-three patients who suffered with upper urinary calculi were treated with PCNL, the puncture and tracts were created using local anesthesia and guided through ultrasound.Of the 1363 patients, 475 patients had complicated renal caluli, 520 patients had kidney pelvic calculi and 368 had upper uretere calculi.Results All of the patients successfully received PCNL under the local anesthesia.Of the 1363 patients five tracts were used in two patients, four tracts were used in four patients, three tracts were used in nine patients, double tracts were used in 25 patents and one tract was used in the remaining patients.The stone-free rate was 96.0% in the kidney pelvic calculi patients, 100.0% in the upper uretere calculi patients, and 90.1% in the complicated renal caluli patients.90.0% patients were find well throught the operation, 10.0% patients find a little pain and solved by another more 5 - 10 ml lidocaine local injection or 50 - 75 mg pethidine hydrochloride intramuscular injection.No case stop operation because of pain or position changed.All without any severe complications such as damaged of liver, spleen, thorax and intestine.Conclusion The PCNL handled under local anesthesia was simple safe and effective, deserved clinical popularizing use.

OBJECTIVETo construct three-dimensional (3D) models of renal stones and perform percutaneous nephrolithotomy (PCNL) virtual surgery simulation. Methods CT images were obtained from 8 patients with renal stones. Images segmentation and reconstruction were performed using MIMICS 10.0 software to construct the 3D model of the renal stones, which provided the anatomical relationships between the kidney and the adjacent organs. The optimal PCNL virtual surgery simulation for each individual case was performed using FreeForm Modeling System on the basis of the 3D model.

RESULTSEight 3D models of renal stone were constructed. The 3D model of the renal stones represented the interrelationships of the stones, intrarenal vessel, and the collecting system with the adjacent anatomical structures. Individualized PCNL virtual surgery simulations including percutaneous puncture, dilatation and pneumatic lithotripsy were performed successfully in all the 8 3D models.

CONCLUSIONDigital 3D model of renal stone provides the reliable and comprehensive imaging information for surgical design, and PCNL virtual surgery simulation has important clinical significance to improve the stone clearance rate and reduce the surgical complications.

OBJECTIVETo investigate the correlation of cytokeratin pan (CKP), vascular endothelial growth factor (VEGF) expression and microvessel density (MVD) to spiral CT manifestations of thymoma.

METHODSEighty-four thymoma patients were underwent spiral CT examination, and 40 of the patients also had enhanced CT examination. All the CT findings were carefully reviewed to analyze their correlation to the expressions of CKP, VEGF and MVD.

RESULTSThe enhancement on spiral CT images increased with the levels of VEGF expression and MVD counting (P<0.01). Significant correlations were observed between VEGF expression, MVD counting and such spiral CT findings as lobular contours, cusp-like or sawtooth-like margins and tumor invasions of the pleural membrane, pericardium and great vessels (P<0.05). CKP expression showed no obvious correlation to these findings by spiral CT.

CONCLUSIONSpiral CT can reflect the pathological characteristics of thymoma, and may serve as a noninvasive modality for preoperative evaluation of thymoma.

OBJECTIVE[corrected] To evaluate the method and technique of single-port laparoscopic radical nephrectomy.

METHODSForm January 2009 to September 2011, 22 patients with renal carcinoma were treated with single-port laparoscopic radical nephrectomy. An incision about 5 cm in length was made through the umbilicus or in the postaxillary line under the 12th rib to establish the peritoneal or retroperitoneal working space. A single-port cannulation was deployed and the operation was carried out using standard and crooked laparoscopic equipment.

RESULTSThe operations were completed successfully in all the 22 cases without conversion to open surgery, but additional trocar was needed in 5 cases. The mean operative time of radical nephrectomy was 150 min (90-240 min). The mean postoperative hospital stay was 7.6 days (3-15 days). The operation left a roughly 5-cm-long scar in all the cases.

CONCLUSIONSingle-port laparoscopic radical nephrectomy is safe and feasible with good cosmetic effect and shows much potential in radical resection of renal carcinoma.

The access negotiations of National Reimbursement Drug List (NRDL) in China from 2017 to 2019 effectively improved the availability and affordability of high-value innovative drugs. However,the actual outpatient reimbursement of most negotiated drugs is lower,which affects the patients" health insurance funds. In this paper,97 negotiated drugs in 337 overall planning cities were selected as samples to analyze the outpatient reimbursement for negotiated drugs. The results showed that the reimbursement level of 40 negotiated drugs was less than 50% in over 70% cities,which can be mainly interpreted as absence or imperfection of outpatient reimbursement policies for special diseases. Finally,this paper puts forward suggestions and protocols for improving the outpatient medical insurance through realizing outpatient overall planning,improving outpatient reimbursement policies for special diseases,and exploring innovative payment,ensuring the achievement of the access to NRDL.

Objective:In order to improve the understanding of the clinical, endoscopic and pathological characteristics of occult primary intestinal lymphangiectasia in infants, and to reduce misdiagnosis and missed diagnosis, we analyzed the clinical manifestations and diagnosis and treatment related data of a case of primary intestinal lymphangitis in Xiamen Children′s Hospital.The patient was admitted to the hospital with bronchopneumonia, mild diarrhea and edema, without decreasing in the number of peripheral blood lymphocytes, showing hypoproteinemia.Albumin infusion failed to alleviate hypoalbuminemia, and then gastroscopy showed that the duodenal segment had white millet like granular protrusion with different sizes and dense density, and the mucosa had extensive leukoplakia like lesions.Pathological examination showed that the small intestinal lymphadenectasia was obvious, and then the small intestinal lymphadenectasia was confirmed.After diagnosis, albumin was infused every two days for two consecutive courses and portagen medium chain fatty acid milk powder was fed.After treatment, the total protein and albumin in the plasma basically rose to the normal level, and the color Doppler ultrasonography of abdomen and chest showed that both pleural effusion and bilateral pulmonary effusion had been absorbed.The retrospective analysis of this case shows that for infants with dropsy caused by the decrease of plasma albumin and globulin, the possibility of excessive protein consumption caused by liver and kidney disease, tumor, tuberculosis and other chronic diseases should be excluded, and small intestinal lymphadenopathy should be considered, gastroscopy should be performed as soon as possible, pathological biopsy should be further improved, early diagnosis and treatment should be carried out as soon as possible And diet intervention treatment to avoid serious consequences caused by not timely handling.

Botulinum toxin is a potent protein toxin produced by Clostridium botulinum. It acts directly on the brain nerve nucleus and peripheral neuromuscular junction, blocking the release of acetylcholine and thereby affecting nerve impulse transmission, ultimately leading to muscle paralysis. Mild cases may present with ocular muscle involvement, whereas severe cases may involve dysphagia, general paralysis, respiratory depression, and even death. This article reports on a patient who experienced severe poisoning symptoms after using type A botulinum toxin obtained through informal channels. The patient was treated with antitoxin on the 13th day after symptoms onset and achieved a significant improvement in their condition.

Heart failure with high prevalence is the endpoint of many cardiovascular diseases. Once diagnosed， patients usually need lifelong medication， which seriously affects their quality of life. The drugs commonly used to treat heart failure include angiotensin-converting enzyme inhibitors， beta-blockers， aldosterone receptor antagonists， and diuretics. However， the long-term use of those drugs can lead to side effects such as hypotension， depletion of body fluid， and electrolyte imbalance and even increase mortality. According to the theory of traditional Chinese medicine （TCM）， Qi deficiency and blood stagnation is the major cause of heart failure and when Qi is not moving， blood is not flowing. Therefore， the TCM clinical treatment of heart failure uses the Chinese medicinal materials which replenish Qi， activate blood， and dispell stasis to treat both internal cause and external symptoms. Recent studies have demonstrated that Chinese herbal medicines such as Astragali Radix， Ginseng Radix et Rhizoma， Notoginseng Radix et Rhizoma， Salviae Miltiorrhizae Radix et Rhizoma， Angelicae Sinensis Radix， as well as the compound formulas such as Buyang Huanwutang， Simiao Yongantang， Qili Qiangxin capsules， and Qishen Yiqi drops， play a significant role in the prevention and treatment of heart failure via replenishing Qi， activating blood， and dispelling stasis. Inhibition of oxidative stress and inflammatory responses， mitigation of myocardial fibrosis， improvement of calcium cycling， and protection of mitochondrial function represent the key mechanisms for the treatment of heart failure with Chinese medicinal materials. Focusing on the pathogenic mechanisms and signaling pathways of heart failure， this paper systematically describes the pharmacological effects， molecular mechanisms， and research progress in the clinical application of Chinese medicinal herbs with effects of replenishing Qi， activating blood， and dispelling stasis and their compound formulas in the prevention and treatment of heart failure， aiming to provide scientific evidence for the development and clinical use of anti-heart failure Chinese medicinal materials.

Circadian rhythm disruption is a universal phenomenon that is associated with a combination of internal and external factors, with internal factors referring to disturbances in the intrinsic regulatory mechanisms of sleep-wake behavior, and external factors including changes in sleep habits, severe sleep deprivation, shift work, social jet lag, prolonged exposure to nighttime light, and late nighttime eating. Shift work, as a common occupational factor, can lead to disruption of the central/ peripheral biological clock which regulates the expression of almost the entire genome, and the disruption of the biological clock can lead to genetic variants, hormonal secretion abnormalities, insulin resistance, oxidative stress, and systemic inflammation, which are risk factors for obesity. In the context of rapid advancement of global economy and industrialization, the prevalence of simple obesity in the traditional cognitive category is increasing in a linear trend, while the incidence of abdominal obesity, which is closely related to metabolic disorders, is also showing an increasing trend. In recent years, the mechanism of circadian rhythm disorder and obesity associated with shift work has attracted much attention, and this article summarized the latest research progress, aiming to provide a basis for the prevention and treatment of obesity caused by circadian rhythm disruption due to shift work.
