ObjectivesTo compare the clinical efficacy and complications of anatomic locking titanium plate （hereinafter referred to as “titanium plate screw”） and intramedullary nail in the treatment of distal tibial fractures.Methods From September 2019 to September 2021， 32 patients diagnosed with AO-A fracture of distal tibia at Sun Yat-sen Memorial Hospital of Sun Yat-sen University were included in this study. Of these， 15 cases were treated with titanium plate screws and 17 cases were treated with intramedullary nails. General surgical indexes， fracture healing time and postoperative operation were compared between the two groups.ResultsAll patients were followed up for 10 to 20 months， with an average of 12 months. The operative time and intraoperative fluoroscopy times of intramedullary nail group were longer than those of titanium plate screw group， but the preoperative waiting time and hospitalization days was less or were fewer than those of titanium plate screw group， the difference was statistically significant （P < 0.05）. There was no significant difference in fracture healing time between the two groups （P> 0.05）. At 6 weeks after operation， VAS scores in both groups were lower than those before operation， with statistically significant difference （P<0.05）. There was no significant difference in VAS scores between the intramedullary nail group and the titanium plate screw group （P> 0.05）. AOFAS scores 6 months after surgery， ankle joint motion and complication rate 1 year after surgery in intramedullary screw group were better than those in titanium plate screw group， and the differences were statistically significant （P< 0.05）. There was no significant difference in AOFAS scores between the two groups at 1 year after operation （P> 0.05）.ConclusionTitanium plate screw and intramedullary nail are both effective methods for the treatment of distal tibial AO-A fracture， and there is no significant difference in long-term clinical efficacy. Intramedullary nail has fewer soft tissue complications， less impact on ankle motion， faster recovery and higher safety， while titanium plate screw has a higher probability of postoperative soft tissue infection. We suggest that in clinical work， preoperative evaluation of patients should be done well. Under the premise of grasping the indications， intramedullary nail has fewer complications and certain advantages.

Objective:To analyze the risk factors of clinically significant bleeding in patients with severe acute pancreatitis (SAP).Methods:The clinical data of SAP patients who were managed at Changhai Hospital affiliated to Naval Medical University from January 1, 2014 to October 31, 2022 were retrospectively analyzed. Twenty-nine SAP patients with clinically significant bleeding were classified to form the bleeding group. There were 23 males and 6 females, aged (56.25±14.01) years old. Another 116 SAP patients with similar general data but with no clinically significant bleeding during the same hospitalization period were included to form the non-bleeding group based on a ratio of 1∶4. There were 94 males and 22 females, aged (56.14±13.96) years old in this non-bleeding group. The general data, modified CT severity index (MCTSI), bedside index for severity of acute pancreatitis (BISAP) and other clinical data of the two groups were collected to determine the risk factors of bleeding in SAP patients.Results:Of the 29 patients with bleeding, 6 had gastrointestinal bleeding, 14 had intra-abdominal bleeding, and 9 had mixed bleeding sites, 15 were cured and discharged, and 14 died. All the 29 SAP patients with bleeding received treatment using drugs. In addition, 8 patients underwent successful hemostasis using digital subtraction angiography, 3 underwent successful endoscopic hemostasis, 2 underwent successful surgical hemostasis, and 2 underwent successful conservative drug hemostasis. Multivariate logistic regression analysis showed that SAP patients with higher MCTSI ( OR=1.824, 95% CI: 1.187-2.802), longer prothrombin time (PT) ( OR=3.431, 95% CI: 1.470-8.007) and higher BISAP ( OR=2.286, 95% CI: 1.054-4.957) had an increased risk of bleeding (all P<0.05). Conclusion:The prognosis of SAP patients was compromised with bleeding. High MCTSI, prolonged PT, and high BISAP were independent risk factors for bleeding in SAP patients.

Objective:To explore the efficacy and safety of Ganhai Weikang capsule (GWC) in the treatment of functional dyspepsia (FD).Methods:A randomized, double-blind, placebo-controlled parallel, multi-center, superiority clinical trial was conducted. From March 2018 to April 2020, totally 324 patients with dyspepsia symptoms, who were diagnosed as chronic non-atrophic gastritis by endoscopy and pathology and met the Rome Ⅳ diagnostic criteria for FD from 7 top hospitals were enrolled, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Heilongjiang Hospital of Traditional Chinese Medicine, Tianjin Academy of Traditional Chinese Medicine Affiliated Hospital, Qilu Hospital of Shandong University, the First Affiliated Hospital of Zhejiang University, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University and the Third Xiangya Hospital of Central South University. The patients were randomly divided into the GWC group and the placebo group according to the ratio of 1∶1. The patients of GWC group were given GWC and the patients of placebo group were given GWC capsule simulant. The patients of both groups orally took capsules before meals, 2.4 g each time and 3 times per day, and the course of treatment was 4 weeks. The main efficacy index was the total clinical effective rate after 4 weeks, and the secondary efficacy index was the changes of clinical symptom scores of upper abdominal pain, upper abdominal burning, postprandial fullness and early satiety. The safety index included laboratory tests and adverse events. Chi-square test and Wilcoxon rank sum test were used for statistical analysis.Results:A total of 320 FD patients were enrolled in the full analysis set (FAS), which included 161 cases in GWC group and 159 cases in placebo group. A total of 298 cases were in the per-protocol set (PPS), 149 cases each in GWC group and placebo group. The results of FAS and PPS both showed that the total clinical effective rates of the GWC group were higher than those of the placebo group (84.5%, 136/161 vs. 44.0%, 70/159 and 83.9%, 125/149 vs. 46.3%, 69/149), and the differences were statistically significant ( χ2=57.07 and 46.32, both P<0.001). In addition, the differences of the total score of main symptoms and each symptom (upper abdominal pain, upper abdominal burning, postprandial fullness and early satiety) before and after treatment of GWC group were all higher than those of the placebo group (FAS: 10 (7, 14) vs. 5 (3, 11); 3 (2, 4) vs. 2 (0, 3); 2 (0, 4) vs. 1 (0, 3); 3 (1, 4) vs. 2 (1, 3); 2 (0, 4) vs. 1 (0, 3). PPS: 10 (7, 13) vs. 5 (3, 11); 3 (2, 4) vs. 2 (0, 3); 2 (0, 4) vs. 1 (0, 2); 3 (1, 4) vs. 2 (1, 3); 2 (0, 4) vs.1 (0, 3)), and the differences were statistically significant (FAS: Z=5.80, 5.91, 3.19, 3.72 and 3.30; PPS: Z=5.14, 5.11, 2.86, 3.21 and 2.84; all P<0.01). The results of FAS and PPS indicated that the improvement rates of main symptoms and each symptom (upper abdominal pain, upper abdominal burning, postprandial fullness and early satiety) of GWC group were all higher than those of the placebo group (FAS: 77.8% (54.6%, 91.3%) vs. 42.9% (28.6%, 61.5%); 100.0% (60.0%, 100.0%) vs. 50.0% (25.0%, 60.0%); 100.0% (50.0%, 100.0%) vs. 50.0% (25.0%, 100.0%); 71.4% (33.3%, 100.0%) vs. 41.4% (25.0%, 66.7%); 100.0% (50.0%, 100.0%) vs. 50.0% (20.0%, 100.0%). PPS: 77.8% (54.2%, 89.5%) vs. 44.0% (28.6%, 65.0%); 100.0% (60.0%, 100.0%) vs. 50.0% (25.0%, 100.0%); 100.0% (50.0%, 100.0%) vs. 50.0% (25.0%, 100.0%); 71.4% (33.3%, 100.0%) vs. 46.4% (25.0%, 66.7%); 100.0% (50.0%, 100.0%) vs. 50.0% (20.0%, 100.0%)), and the differences were statistically significant (FAS: Z=8.60, 7.72, 4.98, 4.24 and 5.61; PPS: Z=7.90, 7.03, 4.49, 3.88 and 4.83; all P<0.001). After 2 weeks of treatment, the differences of the total score of main symptoms and score of each symptom (upper abdominal pain, upper abdominal burning and early satiety) before and after treatment of GWC group were all higher than those of the placebo group (5.0 (3.0, 8.0) vs. 4.0 (2.0, 6.0); 2.0 (1.0, 2.0) vs. 2.0 (0.0, 2.0); 1.5 (0.0, 2.0) vs. 1.0 (0.0, 2.0); 1.5 (0.0, 2.0) vs. 1.0 (0.0, 2.0)), and the differences were statistically significant ( Z=2.95, 3.44, 2.43 and 2.79, all P<0.05). There was no significant difference in the incidence of adverse events between the GWC group and the placebo group (0.6%, 1/163 vs. 0, 0/159). Conclusion:The clinical total effective rate of GWC in the treatment of FD is superior to that of placebo and it has good safety.

Objective:To investigate the predictive value of acute gastrointestinal injury (AGI) score for the severity of acute pancreatitis (AP), infectious pancreatic necrosis and patients′ death.Methods:Clinical data of 719 patients with AP were collected from the AP database of the National Clinical Research Center for Digestive System Diseases from January 2016 to June 2018. According to the severity of the disease, they were divided into MAP group (506 cases), MSAP group (112 cases) and SAP group (101 cases). AGI, APACHEⅡ, MCTSI and BISAP scores were calcululated in the three groups. Receiver operating characteristic curve (ROC) was drawn and the area under the curve (AUC) was calculated. The predictive value of the above four scoring systems for the hospitalization days, disease severity, infectious pancreatic necrosis and death was analyzed, respectively.Results:There were no cases of infectious pancreatic necrosis or death in the MAP group, but there were 9 cases of infectious pancreatic necrosis and 2 deaths in the MSAP group and 19 cases of infectious pancreatic necrosis and 8 deaths in the SAP group. There was a strong correlation between AGI score and AP patients′ hospitalization days ( r=0.619). AUC of AGI, APACHEⅡ, MCTSI and BISAP score in predicting the AP patients′ severity (MSAP+ SAP) was 0.967 (95% CI 0.951-0.982), 0.769(95% CI 0.720-0.899), 0.842(95% CI 0.809-0.875), 0.862 (95% CI0.832-0.893). AUC for forecasting infectious pancreatic necrosis was 0.803, 0.677, 0.692, 0.724, and the 95% CI was 0.724-0.882, 0.573-0.781, 0.582-0.636, 0.801-0.812. AUC for predicting death in patients with AP were 0.915, 0.597, 0.659, 0.812, and the 95% CI were 0.843-0.986, 0.444-0.751, 0.498-0.698 and 0.882-0.926. AGI score had the highest predictive value, followed by BISAP score, and the correlation between these two scores was the closest. The predictive value of AGI combined with BISAP score for infectious pancreatic necrosis and patient death (AUC were 0.837, 0.942, 95% CI were 0.770-0.903, 0.897-0.987) was better than that of AGI and BISAP score alone. Conclusions:AGI score combined with BISAP score is more effective in predicting the severity of AP, the occurrence of infectious pancreatic necrosis or patient death.

Objective:To analyze the efficacy of blood purification (BP) in the treatment of moderately severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP).Methods:The clinical data of 102 patients of MSAP and SAP in Changhai Hospital affiliated with Navy Medical University from December 2015 to March 2019 were retrospectively analyzed. According to the treatment method and prognostic outcome, patients were divided into control group ( n=46) and BP group ( n=56), control survival group ( n=43), and control death group ( n=3), BP survival group ( n=37) and BP death group ( n=19), respectively. Based on BP treatment duration each time, BP group was sub-divided into BP short-term group (4 h≤T<8 h, n=38) and BP long-term group (8 h≤T≤12 h, n=18). General data, laboratory findings, complications, average daily hospitalization cost, prognosis and effects of BP duration on the blood urea nitrogen improvement were recorded. Results:Compared with control survival group, BP survival group had lower levels of lactic acid, urea nitrogen and other metabolites, and SIRS duration was significantly shortened [12(7, 16) days vs 5(3, 9) days, HR=0.19, 95% CI 0.11-0.35, P<0.0001]. The clearance of urea nitrogen in BP short-term group was more obvious than BP long-term group (χ 2==4.44, P=0.035). APACHEⅡ score on admission( OR=1.33, 95% CI 1.087-1.617, P=0.005) and numbers of organ failure ( OR=3.445, 95% CI 1.426-8.323, P=0.006) were important risk factors affecting MSAP and SAP prognosis under BP therapy. For patients with extremely poor prognosis, it was still difficult for BP to reverse the progression trend and prognosis of MSAP and SAP. Conclusions:BP can effectively remove accumulated metabolites at acute stage and shorten the duration of SIRS. BP duration of 4-8 h each time may be more conducive for improving the severity of the disease.

Objective: To explore the predictive value of acute gastrointestinal injury(AGI) grading system in assessing the severity, infectious pancreatic necrosis and death of patients with moderate severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP). Methods: The clinical data of 344 patients with MSAP or SAP admitted in Changhai Hospital Affiliated to Navy Medical University from June 2011 to June 2015 were collected. ROC curve was used and the area under ROC curve (AUC) was calculated. The predictive value of AGI grade for the severity, infectous pancreatic necrosis and death was compared with those of different clinical scores(APACHEⅡ score, MCTSI and Marshal score). Results: Of 344 patients, 81 patients were classified into high AGI grade group (Grade Ⅲ, Ⅳ), while 263 patients were in low AGI grade group(Grade Ⅰ, Ⅱ). The mortality and the number of patients with organ failure were obviously higher in high AGI grade group than those in low AGI grade group (25/81 vs 0/263, 36/45 vs 32/231), and the difference was statistically significant (all PCI 0.916-0.972) and0.779(95% CI 0.723-0.836), respectively, which was higher than those of APACHEⅡ and Marshall score. Conclusions AGI grading system can be applied to better assess the severity of acute pancreatitis, and its predictive value for death and infectious pancreatic necrosis was higher than that of APACHEⅡ, MCTSI and Marshall score.

Objective: To compare the therapeutic value of transnasal gastroscopy and conventional gastroscopy for infective pancreatic necrosis(IPN) through percutaneous endoscopic necrosectomy(PEN). Methods: A total of 24 IPN patients who received PEN for IPN from December 2015 to March 2019 were divided into the conventional gastroscopy group (n=15) and the transnasal gastroscopy group (n=9). The clinical therapeutic indicators such as vital signs, APACHE Ⅱ score changes, operation duration, difference in preoperative and postoperative volumes of peripancreatic necrosis and other indicators were compared between the two groups. Results: There was no significant difference in the variation curve fitting of APACHE Ⅱ scores between the two groups (t=0.378, P=0.710). The operation time of the transnasal gastroscopy group was significantly shorter than that of the conventional gastroscopy group (119.7±47.4 min VS 172.8±56.2 min, P=0.018). Peripancreatic necrotic volume significantly decreased after operation in the transnasal gastroscopy group (404.03±170.73 mL VS 468.9±137.37 mL, P=0.002), and in the conventional gastroscopy group (499.44±227.17 mL VS 722.50±292.96 mL, P<0.001). There was no significant difference in the decrease extent in the conventional gastroscopy group and the transnasal gastroscopy group (223.06±212.92 mL VS 64.87±54.94 mL, P= 0.094). Conclusion On the condition of poor drainage of percutaneous catheter drainage, PEN can significantly reduce the range of necrotic lesions. Transnasal gastroscopy has the advantages in operation time in PEN and clearing deep abscess cavities over conventional gastroscopy.

Objective To investigate the impact of the initial fluid resuscitation with different ratio of crystalloid and colloid on the prognosis of patients with moderate severe acute pancreatitis (MSAP).Methods A retrospective analysis was made by reviewing the clinical data of 72 patients with the diagnosis of MSAP from January 2015 to July 2017 in Shanghai Changhai Hospital.According to crystalloid-colloid ratio,which was the total volume of crystalloid fluid versus colloid fluid in the first 7d at admission,patients were randomly divided into low crystalloid-colloid ratio group (＜ 4.5),middle crystalloid-colloid ratio group (4.5-7.5),and high crystalloid-colloid ratio group (＞ 7.5).The parameters of the fluid resuscitation,the cases progressing into severe acute pancreatitis (SAP),the incidence of multiple organs dysfunction syndrome (MODS) and mechanical ventilation,pancreatic necrosis and infection rate,30-day mortality,the duration of systemic inflammatory response syndrome(SIRS) and the time reaching full amount of enteral nutrition were analyzed.Results There was no statistically significant difference in gender,age,etiology and APACHE Ⅱ score within 24 h at admission in each group,which were comparable.Within the first 7 d,there were no statistic difference in the total volume of fluid infusion and the speed of resuscitation in the three groups.While the total fluid volume in the first 24 h and 72 h [(3 095 ± 1 253) ml vs (2 524 ± 751) ml,(8 005 ± 7 269) ml vs (6 667 ± 1 498)ml],the total volume of crystalloid fluid in the first 7 d [(14 485 ± 3 917) ml vs (11 544 ±2 639) ml],crystalloid-colloid ratio (12.7 ± 4.9 vs 6.0 ± 1.0),the cases of SAP (12 vs 4),MODS (41.7 ％vs 16.0％) in high ratio group were significantly higher than those in middle ratio group,but the total volume of colloid fluid was significantly lower [(996 ± 528) ml vs (1 968 ± 574) ml].In addition,the duration of SIRS [(16.5 ± 15.2) d vs (8.2 ± 6.4) d],and the time reaching full amount of enteral nutrition [(7.2 ±3.6) d vs (4.8 ± 2.4) d] in high crystalloid-colloid ratio group were higher than those in middle crystalloid-colloid ratio group (all P ＜ 0.05).Comparing with middle crystalloid-colloid ratio group,there were no significant difference in the mechanical ventilation rate,pancreatic necrosis and infection rate and 30-day mortality in high ratio group.The total volume of colloid fluid was significantly higher [(3 680 ± 1 310) vs (1 968 ±574)] and the crystalloid-colloid ratio was significantly lower [(3.2 ±0.9) vs (6.0 ± 1.0)] in low ratio group than that in middle ratio group,and there were no statistical differences on other parameters.Conclusions For the patients with MSAP,early fluid resuscitation with the crystatloid-colloid ratio of (4.5-7.5) can decrease the incidence of SAP and MODS,shorten the duration of SIRS,and promote the recovery of intestinal mucosal barrier function.

Objective To analyze the correlation between five cases of female vaginal infection based on the vaginal discharge routine (morphology) and enzyme spectrum.Methods 1 000 patients with vaginal secretion examination were selected as the research subjects of this study.Included patients were treated by routine examination of Trichomonas vaginalis and epithelial cells, white blood cells and Candida, combined pre vaginal secretion of enzymes in the five test.Results The combination of the five enzymes of vaginal secretion examination found in 1 000 patients, the positive patients were 620 cases, accounted for 62.0% of the total, vaginal secretion was more common for aerobic bacteria (AV), accounted for 59.2%.AV combined with aerobic bacteria Candida (VVC) and bacterial vaginosis (BV) was one of the main pathogenic bacteria;data showed that the total positive rate of H2O2 accounted for 73.8%.Conclusion Based on the combination of the five enzymes and the leucorrhea routine examination of vaginal secretions of female vaginitis patients can effectively reflect the specific state of patients with vaginal infection,and it is conducive to the clinical treatment of late symptomatic.

Objective To evaluate the therapeutic effect of percutaneous endoscopic necrosectomy (PEN) in treating infectious pancreatic necrosis (IPN).Methods A retrospective review of clinical data of 6 patients with IPN who received PEN in Changhai Hospital, Second Military Medical University from Dec 2015 to Sep 2016 was performed.Clinical parameters were recorded, including basic information, severity evaluation and therapeutic methods and times.In addition, vital sign parameters and inflammatory marks before and after PEN treatment were compared.Results There were 4 patients with severe acute pancreatitis (SAP) and 2 patients with moderately severe acute pancreatitis (MSAP) in these 6 patients with IPN.Mean APACHEⅡ score was 12 (10~15), and mean MCTSI scores was 9.3(8~10).All 6 patients received a total of 13 times PEN treatments, with a mean of 2.2(1~3) times.Each patient was treated with a mean of 2.5(1~4) drainage tubes placed in the peripancreatic abscess after PEN treatment, and the mean time for drainage was 139 d(106~183 d).Besides, the mean hospitalization time was 116 d (48~223 d).All the patients′ condition was improved significantly after PEN treatment, including reduced heart rate, body temperature and inflammatory markers, without bleeding or other serious complications.Only 1 patient had pancreatic fistula after treatment, and no patients needed open abdominal drainage surgery.Patients with higher MCTSI scores likely required more times of PEN and more drainage catheters, longer length of drainage and hospital stay.Conclusions PEN was safe and effective for treating patient with IPN, but those with higher MCTSI scores were associated with more PEN treatments, more drainage tubes, and longer time of drainage and hospitalization.
