The levels of dopamine D1 and D2 receptor proteins in the striatum were significantly decreased by 28% and 29%, respectively (P

OBJECTIVE:To provide reference for the application of position number in the pharmacy drug management. METHODS:Three-dimensional coding method was used for coding the position number. The mentioned method was combined with hospital information management system (HIS) for the out of storage,deployment and inventory. Memory field assumptions method was used to compare the size of field memorized by pharmacist in inpatient pharmacy before and after management of posi-tion number. Sampling controlled trial was conducted to compare the drugs deployment time and walking distance of pharmacists in inpatient pharmacy and drug storehouse before and after coding management of position number. RESULTS:After management of coding management in inpatient pharmacy,the memory required field was decreased from 1 028 to 25,deployment time of pharma-cists was decreased from(36.57±0.82)min to(24.20±0.33)min,and the walking distance was decreased from(79.17±0.29)m to(38.59±0.56)m. After management of coding management in drug storehouse,deployment time of pharmacists was decreased from(61.86±0.44)min to(47.18±0.63)min,and the walking distance was decreased from(129.53±0.58)m to(68.97±0.32) m. CONCLUSIONS:The drug coding management of position number can improve the deployment efficiency and reduce the brain and physical quantity of pharmacists.

The judgment of early curative effect is important to the treatment of nasopharyngeal carcinoma and the prognosis of the patients.As a rapid imaging technique,magnetic resonance diffusion weighted imaging (DWI) is used to quantitatively analyze the changes of water molecules in the tissue by means of apparent diffusion coefficient (ADC),so as to diagnose the small lesions of nasopharyngeal carcinoma accurately,evaluate the early curative effect and observe the prognosis.With the continuous improvement and progress of MRI and data analysis technology,DWI in the diagnosis and treatment of nasopharyngeal carcinoma shows a broader application prospect.

OBJECTIVE: To examine the expression of HIF-1alpha and CD34 in nasopharyngeal carcinoma and nasopharyngitis tissues, evaluate the role of HIF-1alpha and microvessel density (MVD) in nasopharyngeal carcinoma, probe the relationship between HIF-1alpha and MVD. METHOD: The expression of HIF-1alpha was detected in 58 cases with nasopharyngeal carcinoma and 20 samples of nasopharyngitis tissues by immunohistochemical staining SABC methods and SP methods. MVD in tumor was counted by immunostaining with CD34 and analyzed with clinicopathologic parameters. RESULT: The positive rate of HIF-1alpha was 79.31% and 10.00% respectively in nasopharyngeal carcinoma and nasopharyngitis tissues, there was significant difference between them (P<0.01). MVD was 39.74+/-7.41 and 18.43+/-3.24 respectively in nasopharyngeal carcinoma and nasopharyngitis tissues, there was significant difference between them (P<0.01). The expression of HIF-1alpha and MVD were significantly higher in nasopharyngeal carcinoma and in lymph node metastasis group than in no-metastasis group. In different clinical stage, the expression of HIF-1alpha (P<0.05) and MVD (P<0.01) was different. The expression of HIF-1alpha was positively correlated with MVD (P<0.01). CONCLUSION HIF-1alpha may be involved in carcinogenesis, invasion and metastasis of NPC. Visualization plays a key role in invasion and metastasis of NPC. The expression of HIF-1alpha was positively correlated with tumor visualization in NPC. HIF-1alpha is likely to be a potential target of anticancer therapy.

Objective:To investigate the safety and feasibility of transgluteal percutaneous drainage using double catheterization cannula in the treatment of deep pelvic abscess.Methods:A retrospective analysis of the clinical data of patients who underwent transgluteal percutaneous drainage using double catheterization cannula with deep pelvic abscesses admitted to the Jinling Hospital from May 2017 to September 2020 was conducted. Seven patients were enrolled, including 5 males and 2 females, who aged 26-74 (median 53.0) years old, and all of them had digestive fistula. One male patient was punctured again due to the tube falling off, and a total of 7 patients underwent 8 times of transgluteal percutaneous drainage, all under the guidance of CT. The puncture and drainage steps of the double catheterization cannula group are as follows: (1) Locate the puncture point under CT in the lateral position; (2) Place the trocar into the abscess cavity; (3) Confirm that the trocar is located in the abscess cavity under CT; (4) Pull out the inner core and insert into the double catheterization cannula through the operating hole; (5) Confirmthat the double catheterization cannula is located in the abscess cavity under CT; (6) The double catheterization cannula is properly fixed to prevent it from falling off. The white blood cells, C-reactive protein (CRP), procalcitonin, and interleukin-6 (IL-6) of all patients before the drainage and 1 days, 3 days, and 5 days after the drainage were collected, as well as the bacterial culture results of the drainage fluid. The changes of various infection biomarkers before and after the drainage were compared.Results:All 7 patients were cured. No complications such as hemorrhage and severe pain were observed. The average time with drainage tube was 60.8 (18-126) days. Five patients finally underwent gastrointestinal reconstruction surgery due to gastrointestinal fistula. The median serum interleukin-6 of patients before drainage, 1 day, 3 days and 5 days after drainage were 181.6 (113.0, 405.4) μg/L, 122.2 (55.8, 226.0) μg/L, 59.2 (29.0,203.5) μg/L and 64.1 (30.0,88.4) μg/L, respectively.The level of serum interleukin-6 at 3 days and 5 days after drainage was significantly lower than before drainage ( F=3.586, P=0.026). Although the white blood cell count, C-reactive protein, and procalcitonin decreased gradually after drainage compared with before drainage, the difference was not statistically significant (all P>0.05). Conclusion:Transgluteal percutaneous drainage with double catheterization cannula is simple and effective, and can be used for the treatment of deep pelvic abscess.

Radiomics and radiogenomics are used to provide comprehensive tumor biological characte-ristics and further clinical information by extracting,screening and analyzing the most valuable quantitative ra-diomics features. In recent years,numerous studies have shown that radiomics plays a role in the diagnosis, treatment and predicting efficacy and prognosis of lung cancer. Radiogenomics shows a great value in the pre-diction of lung cancer gene phenotype and individualized precision treatment by combining radiomics features with genomics,proteomics and so on. Radiomics and radiogenomics are non-invasive,quantitative,and repro-ducible,and they can provide multidirectional tumor biological characteristics,which are expected to be widely used in the precise medical treatment of lung cancer in the future.

OBJECTIVE: To investigate the role of VEGF in angiogenesis of nasopharyngeal carcinoma tissue. METHOD: Serum and tissue VEGF were detected by the quantitative enzyme-linked immunosorbent assay (ELISA) method both in 62 nasopharyngeal carcinoma without therapy and 20 nasopharyngitis. The expression of microvessel density in tissue of nasopharyngeal carcinoma and nasopharyngitis were detected by immunohistochemical method. RESULT: (1) There was no significant relationship compared VEGF and MVD in nasopharyngeal carcinoma patient, gender and ages (P>0.05), while the expression of VEGF and MVD in later stage (III+IV) were significant higher than that in earlier stage (I+I) (P<0.01), and in positive lymph node group or metastasis group were higher than in negative group (P<0.01); (2) The expression of VEGF and MVD in nasopharyngeal carcinoma serum and tissue were higher than in nasopharyngitis (P<0.05); (3) There was positive correlation between VEGF and MVD in nasopharyngeal carcinoma tissue (r=0.865, P<0.01), but negative correlation in their serum (r=0.328, P>0.05). CONCLUSION VEGF could induce angiogenesis in nasopharyngeal carcinoma tissue, and play an important role in progression in nasopharyngeal carcinoma, VEGF could be an important marker for monitoring prognosis of disease.

Objective:To investigate the risk factors of refracture of the injured vertebrae after percutaneous vertebral augmentation for acute symptomatic thoracolumbar osteoporotic compression fractures (ASTOCFs).Methods:A case-control study was conducted to analyze the clinical data of 2 237 ASTOCFs patients admitted to three hospitals from January 2010 to January 2019. There were 569 males and 1 668 females, with age range of 50-85 years [(66.7±4.8)years]. The patients underwent percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP). According to the radiographic outcomes, the patients were divided into refracture group ( n=315) and non-refracture group ( n=1 922). Data were recorded for the two groups, including basic demographics (gender, age, height and weight), personal habits (smoking and alcohol consumption), basic diseases (diabetes, hypertension, coronary heart disease and chronic obstructive pulmonary disease), preoperative bone mineral density, fracture segment, number of injured vertebrae, surgical method (PVP or PKP), surgical approach, bone cement viscosity, distance from cement to the upper and lower endplate, cement volume in injured vertebrae, cement leakage, postoperative exercise, and postoperative anti-osteoporosis treatment. The above data were analyzed to identify their correlation with postoperative refracture of the injured vertebrae by univariate analysis. The independent risk factors for postoperative refracture of the injured vertebrae were determined by multivariate Logistic regression analysis. Results:Univariate analysis showed that refracture of injured vertebrae was correlated with gender, age, diabetes, fracture segment, surgical method, distance from cement to the upper and lower endplate, postoperative exercise, and postoperative anti-osteoporosis treatment ( P<0.05 or 0.01), but there was no correlation with height, weight, smoking, alcohol consumption, hypertension, coronary heart disease, chronic obstructive pulmonary disease, preoperative bone mineral density, number of fractured vertebrae, surgical approach, bone cement viscosity, cement volume in injured vertebrae or cement leakage (all P>0.05). Multivariate Logistic regression analysis showed that female ( OR=1.92, 95% CI 1.34-2.64, P<0.01), age ≥80 years ( OR=1.21, 95%CI 1.17-1.25, P<0.01), diabetes ( OR=1.92, 95% CI 0.44-2.55, P<0.01), thoracolumbar fracture ( OR=1.46, 95% CI 1.82-7.51, P<0.05), PKP ( OR=4.56, 95% CI 0.86-1.44, P<0.05), no postoperative exercise ( OR=2.14,95% CI 0.27-0.38, P<0.01), and no postoperative anti-osteoporosis treatment ( OR=2.36,95% CI 0.13-0.47, P<0.05) were positively correlated with refracture of injured vertebrae. Conclusion:Female, age ≥80 years, diabetes, thoracolumbar fracture, PKP, no postoperative exercise, and no postoperative anti-osteoporosis treatment are independent risk factors for refracture of injured vertebrae after percutaneous vertebral augmentation for ASTOCFs.

Objective:The purpose of this study was to analyze the course and outcome of patients with combined entero-atmospheric fistulas in open abdomen treatment.Methods:In this retrospective observational study, we collected data on 214 patients with open abdomen complicated by entero-atmospheric fistulas admitted to Research Institute of General Surgery, Jinling Hospital, Affiliated Hospital of Medical School from January 2012 to January 2021. We collected their basic characteristics, aetiology, treatment plan, and prognosis, including the durations of hospitalization and open treatment, time to resumption of enteral nutrition, duration and prognosis of definitive surgery, and overall prognosis.Results:Of the 214 patients with open abdomen complicated with entero–enteral fistulas, 23 (10.7%) died (11 of multiple organ failure caused by abdominal infection, five of abdominal cavity bleeding, four of pulmonary infection, one of airway bleeding, one of necrotizing fasciitis, and one of traumatic brain injury). The remaining 191 underwent definitive surgery at our hospital. The patients who underwent definitive surgery were predominantly male (156 patients, 81.7%); their age was (46.5±2.5) years. Trauma and gastrointestinal tumors (120 cases, 62.8%) predominated among the primary causes. The reasons for abdominal opening were, in order, severe abdominal infection (137 cases, 71.7%, damage control surgery (29 cases, 15.2%), and abdominal hypertension (25 cases, 13.1%). Temporary abdominal closure measures were used to classify the participants into a skin-only suture group (104 cases) and a skin-implant group (87 cases). Compared with the skin-implant group, in the skin-suture-only group the proportion of male patients was lower (74.7% [65/87] vs. 87.5% [91/104], χ 2=5.176, P=0.023), the mean age was older ([48.3±2.0] years vs. [45.0±1.9] years, t=-11.671, P<0.001), there were fewer patients with trauma (32.2% [28 /87] vs. 58.7% [61/104), χ 2=13.337, P<0.001), intensive care stays were shorter ([8.9±1.0] days vs. [12.7±1.6] days, t=19.281, P<0.001), total length of stay was shorter ([29.3±2.0] days vs. [31.9±2.0] days, t=9.021, P<0.001), there was a higher percentage of colonic fistulas (18.4% [16/87] vs. 8.7% [9/104], χ 2=3.948, P=0.047), but fewer multiple fistulas (11.5% [10/87] vs. 34.6% [36/104], χ 2=14.440, P<0.001). As to fistula management, a higher percentage of fistula sealing methods using 3D-printed intestinal stents were implemented in the skin-only suture group (60.9% [53/87] versus 43.3% [45/104], χ 2=5.907, P=0.015). Compared with the implant group, the skin-only suture group had a shorter mean time to performing provisional closure ( [9.5±0.8] days vs. [16.0±0.6] days, t=66.023, P<0.001), shorter intervals to definitive surgery ( [165.0±10.7] days vs. [198.9±8.3] days, t=26.644, P<0.001), and less use of biopatches (56.3% [49/87) vs. 71.2% [74/104], χ 2=4.545, P=0.033). Conclusions:Open abdomen complicated with entero-enteral fistulas is more common in male, and is often caused by trauma and gastrointestinal tumor. Severe intra-abdominal infection is the major cause of open abdomen, and most fistulae involves the small intestine. Collection and retraction of intestinal fluid and 3D-printed entero-enteral fistula stent sealing followed by implantation and skin-only suturing is an effective means of managing entero-enteral fistulas complicating open abdominal cavity. Earlier closure of the abdominal cavity with skin-only sutures can shorten the time to definitive surgery and reduce the rate of utilization of biopatches.
