ObjectiveTo observe the clinical efficacy and possible mechanisms of Xianglian Huazhuo Granules （香连化浊颗粒， XHG） in the treatment of chronic atrophic gastritis with intestinal metaplasia. MethodsA total of 140 patients with chronic atrophic gastritis and intestinal metaplasia were randomly divided into a treatment group and a control group， with 70 cases in each group. The treatment group received 12.5 g of XHG orally， twice daily. The control group received 12.5 g of placebo orally， twice daily. Both groups were treated for 6 months. The traditional Chinese medicine （TCM） symptom scores， pathological types， serum tumor markers of the digestive system， and serum bile acids （TBA）， interleukin-23 （IL-23）， and Dickkopf-related protein 1 （DKK-1） levels were observed before and after treatment. Safety indicators and adverse events were recorded. After treatment， TCM syndrome efficacy and pathological types were evaluated， and patients were followed up for 18 months with gastric endoscopy and pathological results， which were compared with the results after treatment finished. ResultsTwo patients dropped out in the control group， and a total of 168 cases were included in the final analysis， 70 in the treatment group and 68 in the control group. The treatment group showed a significant reduction in TCM symptom scores， serum TBA， IL-23， and DKK-1 levels， and a significant increase in alpha-fetoprotein （AFP）， carbohydrate antigen 125 （CA125）， carbohydrate antigen 199 （CA199） levels； in the control group， carcinoembryonic antigen （CEA）， CA125， CA199 levels significantly increased （P＜0.05 or P＜0.01）； and carbohydrate antigen 242 （CA242） level in both the treatment group and the control group decreased significantly （P＜0.01）. The treatment group had lower TCM symptom scores and lower levels of serum TBA， IL-23， and DKK-1 compared to the control group （P＜0.05）. The effective rate for TCM syndrome efficacy in the treatment group was 80.00% （56/70）， significantly higher than the 20.59% （14/68） in the control group （P < 0.05）. The effective rate for pathological classification in the treatment group was 72.73% （8/11） for mixed intestinal metaplasia， significantly better than 46.15% （6/13） in the control group （P＜0.05）. No adverse events were reported in either group. Among 40 patients who had a follow-up endoscopy after one year， 21 were from the treatment group， of whom 11 showed reduced intestinal metaplasia， 9 showed no significant changes， and 1 had worsened； while 19 patients in the control group had 4 with reduced intestinal metaplasia， 13 with no significant changes， and 2 with worsened conditions. No cancer was detected in either group. The treatment group showed significantly better improvement in intestinal metaplasia on follow-up gastric endoscopy pathology than the control group （P＜0.05）. ConclusionXHG can significantly improve the clinical symptoms in patients with chronic atrophic gastritis and intestinal metaplasia and reduce the degree of mixed intestinal metaplasia. The mechanism may involve lowering serum TBA， DKK-1， and IL-23 levles， thus delaying the progression from inflammation to cancer.

Objective To investigate the current status and awareness of pharmaceutical services in hospitals in Guizhou province and to provide a reference for exploring and carrying out pharmaceutical service fees.Methods The questionnaire was designed by the"wjx.cn"website.Three kinds of questionnaires were designed for pharmacists,doctors,nurses,and patients as the research objects,with corresponding differences in some questions,and promoted on WeChat,Dingxiangyuan,and other network platforms.Results A total of 655 questionnaires were collected,and 639 valid questionnaires were recovered,with an effective recovery rate of 97.56%.324 pharmacists(50.70%),82 doctors and nurses(12.83%),233 patients(36.46%)were surveyed.The average approval score of these three groups of respondents on pharmaceutical service fees was 4.67,4.23,and 4.22,respectively(full score:5).Conclusions Overall,pharmacists'professional services have received support from medical staff and patients.However,patients'pharmaceutical service projects currently focus on dispensing services.The recognition of pharmacists'work and the public's awareness of pharmaceutical services can be improved by enhancing the professional ability of pharmacists,strengthening publicity and guidance,and exploring"Internet+pharmaceutical services",etc.,to promote the sustainable development of pharmaceutical services.

Hepatohilar cholangiocarcinoma is a common malignant tumor of the biliary system,and radical surgery is one of the important treatment methods.Due to the narrow space at the hi-lum and the high rate of anatomical variation,radical surgery is challenging.By using medical imag-ing technology and 3D reconstruction,surgeons can accurately determine the stage and classifica-tion of hilar cholangiocarcinoma preoperatively.They can assess the tumor's resectability by Ac-cording to the bile duct separation limit points(U point,P point)and anticipate the impact of portal vein,bile duct,and arterial variations on the surgical plan,thereby improving the rate of radical re-section and reducing complication rates.

Objective To construct a non-drug intervention program for acute chemotherapy-related nausea and vomiting in children with cancer and to evaluate its efficacy.Methods Through literature review and Delphi expert correspondence,a non-drug intervention program for acute chemotherapy-related nausea and vomiting in children with cancer was constructed.By the convenience sampling method,200 consecutive children who received chemotherapy in the neurosurgery department of a tertiary children's hospital in Zhejiang province from February 1 to October 31,2023 were included as the application subjects,with 100 cases in an experimental group and 100 cases in a control group.The experimental group applied the non-drug intervention program of acute chemotherapy-related nausea and vomiting in children with cancer,and the routine measures were applied in the control group.The incidence of nausea and vomiting,severity of vomiting,compliance rate of normal sleep duration and incidence of negative emotions were compared between the 2 groups.Results The recovery rate of the valid questionnaire in 2 rounds of expert letter inquiry was 100％,and the expert authority coefficient was 0.836.The Kendall harmony coefficients were 0.471 and 0.820(P＜0.001),and the final non-drug intervention program for pediatric acute chemotherapy-related nausea and vomiting included 5 primary,14 secondary and 18 tertiary items.The results showed that the incidence of nausea,vomiting and negative emotions in the experimental group were lower than that in the control group,with statistically significant differences(P＜0.05).The severity of vomiting was less than it in the control group,with statistically significant difference(P＜0.05).The standard rate of normal sleep time was higher than that of the control group,and the difference was statistically significant(all P＜0.05).Conclusion The non-drug intervention program of chemotherapy-related nausea and vomiting in children is scientific and feasible,and the implementation of the program can reduce the incidence of nausea,vomiting and negative emotions,reduce the severity of vomiting,and improve the standard rate of normal bedtime in children.

Lymphatic leakage and lymphatic cysts are common complications after radical resection of middle- and high-risk prostate cancer. There are many treatment methods but the effect is not accurate. This article reports two patients who were diagnosed by lipiodol lymphangiography under ultrasound guidance and used a mixture of n-butyl cyanoacrylate and lipiodol to embolize lymphatic leakage. Among them, one patient achieved success after one session of interventional embolization. Another patient achieved success after 3 interventions and embolization. Two patients had no complications related to lymphatic interventional therapy, and no lymphatic leakage recurred during the 3-month follow-up. Ultrasound-guided lymphangiography and lymphatic embolization through the inguinal lymph nodes are a feasible option for the treatment of refractory lymphoma leakage

Objective:To summarize the experience of Bacillus Calmette-Guerin(BCG) in the treatment of bladder cancer secondary to renal transplantation.Methods:The clinical data of 5 patients who underwent BCG bladder irrigation after secondary bladder cancer after kidney transplantation in Tianjin First Central Hospital from January 2015 to December 2019 were analyzed. There were 1 male and 4 female cases. During the period of immunosuppression after transplantation, 1 case developed secondary high-level non-muscular invasive bladder cancer (NMIBC), 3 cases developed secondary low-grade NMIBC, and 1 case developed secondary glandular cystitis (4 cases). The mean age of the 5 patients with secondary bladder cancer was 59.7±4.0 years. Case one with high level NMIBC was treated with transurethral resection of bladder tumor (TURBT) and postoperative irrigation of epirubicin. Case 3 and 5 with low-level NMIBC accepted regular postoperative irrigation of gemcitabine. No irrigative therapy was performed in case 2. Bladder cancer recurred in case 1, 2, 3 and 5 after 20.1±9.7 months. TURBT was observed in all the 4 patients, among which 3 were of high grade NMIBC and 1 was of low grade NMIBC. Four patients were irrigated with BCG 2 weeks after operation. Postoperative pathology indicated low-level NMIBC in case 4, and BCG was irrigated 2 weeks after the operation. During perfusion therapy, immunosuppressive agents were continued.Results:During BCG perfusion, 4 of the 5 cases showed BCG related local inflammation, among which 2 cases presented symptoms of bladder irritation, 1 case presented hematuria, and 1 case presented hematuria with low fever. Patients with frequent urination, pain in urine, hematuria and other symptoms improved after drinking plenty of water, taking bed rest and taking levofloxacin (0.5g/ day ×7 days). Patients with low fever were treated with antipyretic treatment. No antituberculous agents were used prophylactically during BCG perfusion. There were no symptoms of tuberculosis infection or sepsis. The function of transplantated kidney was normal and no tendency of rejection. The 5 patients were followed up for 7-24 months, 1 patient was lost to follow-up after 7 months of BCG bladder perfusion, and no tumor recurrence or metastasis was found in 5 patients during the follow-up.Conclusions:The use of immunosuppressive agents does not reduce the biological activity of BCG, and BCG does not increase the risk of systemic toxicity or affect the function of transplanted kidneys in immunocompromised patients. BCG is a treatment option for bladder cancer secondary to renal transplantation.

Nephron sparing surgery ( NSS ) has become the standard treatment of small renal cancer . NSS have the similar curative effect compared with radical nephrectomy and preserve the kidney fuction. However, positive surgical margins after NSS is increasing and has attracted more and more attention. We will discuss positive surgical margins related factors and how to reduce the positive surgical margins in this review.

Objective To explore the value of methylation of SDC2 and SFRP2 genes promoter in fecal DNA for colorectal cancer ( CRC) screening. Methods All stool samples were enrolled from Changhai Hospital of Naval Medical University, the Tenth People' s Hospital of Tongji University and the Seventh Medical Center of Chinese People's Liberation Army General Hospital. A total of 500 stool samples collected from March 2018 to December 2018 were allocated to CRC group ( 132 CRCs ) , adenoma group ( 38 advanced adenomas), healthy group (152 healthy individuals), interferential group (178 cases of benign colorectal disease or other non-colorectal tumors) and negative group (330 cases composed of healthy group and interferential group ) . The promoter methylation of fecal SDC2 and SFRP2 genes was detected by methylation-specific PCR (MSP) and compared with single gene methylation and the fecal immunochemical tests ( FIT) to evaluate its sensitivity and specificity. Results The stool sample analysis showed that the sensitivity of combined detection of SDC2 and SFRP2 in CRC group was 97. 73％ ( 129/132 ) , which was significantly higher than those of the single gene SDC2 test [ 70. 45％ ( 93/132) , P=0. 000] , single SFRP2 test [81. 82％ (108/132), P=0. 000] and FIT [69. 70％ (92/132), P=0. 000]. In adenoma group, the sensitivity of combined detection of SDC2 and SFRP2 was 57. 89％ (22/38), which was significantly higher than those of the single gene SDC2 test [ 15. 79％ ( 6/38 ) , P= 0. 000 ] and FIT [ 21. 05％ ( 8/38 ) , P=0. 021] , with no significant difference compared with that of SFRP2 test [ 47. 37％ ( 18/38) , P=0. 358] . In healthy group, the specificity of combined detection of SDC2 and SFRP2 was 98. 68％ (150/152), with no significant difference compared with those of single gene SDC2 test [ 100. 00％( 152/152) , P=0. 156] , single SFRP2 test [98. 68％ (150/152), P=1. 000] or FIT [95. 39％ (145/152), P=0. 091]. Specificities of combined detection of two genes in interferential and negative groups were 90. 45％ ( 161/178) and 94. 24％( 311/330) , which were significantly higher than 73. 03％( 130/178, P=0. 000) and 83. 33％( 275/330, P=0. 000) of FIT, respectively. Conclusion The combined detection test of methylation of SDC2 and SFRP2 is superior to single gene test, whose sensitivity of CRC and aggressive adenoma and specificity of distinguishing benign and malignant lesions are higher than FIT, which has potential application value.

Objective: Systematic assessment of the effect of positive margin on recurrence and metastasis in patients with renal cell carcinoma who underwent partial nephrectomy. Methods: The literature were searched on the rate of recurrence and metastasis in patients with positive margin and partial nephrectomy published in PubMed, Embase, Cochrane, China Biomedical Literature Database, China Knowledge Network, VIP Chinese Science and Technology Journal Database, and Wanfang Chinese Database up to December 2018. The quality of the literature included in this study was evaluated by two reviewers, and a meta-analysis was performed on the literature that met the inclusion criteria using the Revman 5.0 statistical software provided by Cochrane Collaboration. Results: A total of seven articles were included, six of which were case-control studies, and the other one was a cohort study. These seven articles consisted of 6 928 patients, including 407 positive margins and 6 521 negative margins. For recurrence and metastasis, 407 positive margins were composed of 25 recurrences and 21 distant metastases, while 6 521 negative margins consisted of 68 recurrence and 96 distant metastasis. The disease-free survival rate of patients with positive margins is lower than that with negative margins (OR=4.92, 95%CI 2.66-9.08, P<0.001). The results of subgroup analysis of patients with recurrence and metastasis based on positive margin exhibited that positive margin increased the risk of recurrence in patients undergoing partial nephrectomy (OR=5.05, 95%CI 2.06-12.37, P<0.001), as well as the risk of metastasis (OR=3.70, 95%CI 2.18-6.26, P<0.001). Since different studies consisted of patients with different tumor staging, a stratified analysis was conducted and the disease-free survival rate of patients with positive margins decreased compared with that of negative margins (OR=4.13, 95%CI 2.54-6.70, P<0.001), although there were differences in the staging of tumor patients included in different studies, which did not weaken the results. Conclusions Positive margins increase the risk of recurrence and metastasis in patients undergoing partial nephrectomy.

OBJECTIVE: To investigate the clinical features, accompanying gene mutation characteristics and prognostic factors of adult patients with acute myeloid leukemia with mutated NPM1 (NPM1AML). METHODS: Seventy-three patients with newly diagnosed adult NPM1AML were selected. The mutations of 22 genes were detected by second generation sequencing and 43 fusion genes of AML were detected by real-time fluorescent quantitative PCR. The Kaplan-Meier survival curve and Cox multivariate regression analysis were used to study the prognostic factors. RESULTS: A total of 74 NPM1 site mutations were detected in 73 patients with NPM1AML. The incidence rates were 92.0% L287fs, 2.7% Q289fs and W288fs, 1.4% L258fs and Q289H, among which 1 patient had 2 NPM1 mutations; the different mutation sites had no effect on the prognosis of NPM1AML. The median value of NPM1 variant allele frequency (VAF) was 35.4% (1.8%-56.6%). Based on the uppermost quartile of 38.4%, the patients were classified as NPM1 VAF>38.4% (NPM1AML) and NPM1 VAF≤38.4% (NPM1AML). Compared with NPM1AML, the early mortality rate was statistically significantly higher (33.3% vs 7.3%, P<0.05), and median EFS (148 d，95%CI 58-238 d vs 372 d，95%CI 264-480 d) (P<0.01) and median OS (179 d 95%CI 6-352 d vs 444 d) (P<0.01) were significantly shorter in NPM1 AML. A total of 126 accompanying gene mutation sites were detected in 87.7% of patients with NPM1AML. The patients with NRAS gene mutation displayed a higher rate of complete remission (100% vs 58%) (P<0.05) and longer median OS (not reached to 320 d, 95%CI 150-490 d) (P<0.05). The 43 fusion genes were examined in 65 out of 73 cases of NPM1AML, and in all the patients the fusion gene test was negative. Multivariate analysis showed that NPM1 VAF>38.4% was an independent prognostic factor for EFS (HR=3.1, 95% CI 1.6-6.4, P<0.01) and OS (HR=3.0, 95% CI 1.4-6.2, P<0.01). CONCLUSION The NPM1 gene mutation in AML patients often is accompanied by other gene mutations, while the coexistence of fusion genes is rare; high NPM1 mutant allele burden is an independent prognostic factor for adult AML patients with mutated NPM1.
