Objective To investigate the clinical efficacy of modified Banxia Houpu Decoction plus Deanxit for the treatment of cancer-related depression(CRD)of phlegm blended with qi type.Methods Sixty-four CRD patients with phlegm blended with qi type were randomly divided into the treatment group and the control group,with 32 patients in each group.The control group was given oral use of Deanxit,and the treatment group was treated with modified Banxia Houpu Decoction plus Deanxit orally.The course of treatment covered 4 weeks.The changes of Karnofsky Performance Status(KPS)scores,self-rating depression scale(SDS)scores,and traditional Chinese medicine(TCM)syndrome scores in the two groups were observed before and after the treatment.Moreover,the efficacy for improving KPS scores and TCM syndrome efficacy in the two groups were also evaluated.Results(1)After 4 weeks of treatment,the total effective rate for improving KPS scores in the treatment group was 90.63%(29/32),and that in the control group was 78.13%(25/32).The intergroup comparison showed that the efficacy for improving KPS scores in the treatment group was significantly superior to that in the control group(P＜0.01).(2)In terms of the efficacy of TCM syndromes,after 4 weeks of treatment,the total effective rate for improving TCM syndrome scores in the treatment group was 87.50%(28/32),and that in the control group was 40.63%(13/32),and the efficacy of TCM syndromes in the treatment group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the KPS scores in the treatment group were significantly increased compared with those before treatment(P＜0.05),and the KPS scores in the control group tended to increase compared with those before treatment,but the difference was not statistically significant(P＞0.05).The intergroup comparison showed that the effect on increasing KPS scores in the treatment group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the SDS scores in the two groups were lower than those before treatment(P＜0.05),and the effect on lowering SDS scores in the treatment group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the TCM syndrome scores of the two groups were lower than those before treatment(P＜0.05),and the effect on lowering TCM syndrome scores in the treatment group was significantly superior to that in the control group(P＜0.05).Conclusion Modified Banxia Houpu Decoction plus Deanxit exerts certain effect for the treatment of CRD of phlegm blended with qi type.The combined therapy can effectively improve the depression mood and quality of life of the patients,and its efficacy is superior to that of Deanxit alone.

Objective:To clarify the application effect of information-guided enteral nutrition-associated diarrhea (ENAD) management process in patients with chronic obstructive pulmonary disease (COPD) undergoing non-invasive assisted ventilation.Methods:A mixed cohort study of pre- and post-control was conducted. Thirty-nine patients with COPD who were admitted to the emergency intensive care unit (ICU) of Huzhou First People's Hospital from July 1, 2021 to July 31, 2022 were enrolled. Taking the completion of the software development of ENAD management software for critically ill patients on January 28, 2022 as the time node, 20 patients admitted from July 1, 2021 to January 28, 2022 were set as the control group, and 19 patients admitted from January 29 to July 31, 2022 were set as the observation group. The two groups of patients received the same enteral nutrition support treatment, and the control group implemented the conventional ENAD treatment process with enteral nutrition intolerance disposal process as the core. On the basis of the control group, the observation group implemented the information-guided ENAD treatment process, and the system software actively captured the information of ENAD patients and reminded the medical team to improve the patient's diarrhea-related examination and provide alternative treatment plans. The duration of antidiarrhea, feeding interruption rate, and energy and protein intake, blood biochemical indexes, incidence of abnormal blood electrolyte metabolism, daily continuous non-invasive assisted ventilation and endotracheal intubation after 7 days of targeted diarrhea intervention were compared between the two groups.Results:Except for the basal pulse rate, there were no significant differences in gender distribution, age, and vital signs, basic nutritional status, arterial blood gas analysis and blood biochemistry at admission between the two groups, indicating comparability between the two groups. When ENAD occurred, the patients in the observation group obtained earlier cessation of diarrhea than those in the control group [days: 3.00 (2.00, 3.25) vs. 4.00 (3.00, 5.00), P < 0.01], and the feeding interruption rate was significantly lower than that in the control group [10.53% (2/19) vs. 65.00% (13/20), P < 0.01]. After 7 days of diarrhea intervention, the energy intake of the observation group was significantly higher than that of the control group [kJ·kg -1·d -1: 66.28 (43.34, 70.36) vs. 47.88 (34.60, 52.32), P < 0.01], the levels of hemoglobin (Hb), albumin (Alb) and serum prealbumin (PAB) were significantly higher than those in the control group [Hb (g/L): 119.79±10.04 vs. 110.20±7.75, Alb (g/L): 36.00 (33.75, 37.25) vs. 31.00 (30.00, 33.00), PAB (mg/L): 155.79±25.78 vs. 140.95±14.97, all P < 0.05], the daily continuous non-invasive assisted ventilation duration was significantly shorter than that of the control group [hours: 14 (12, 16) vs. 16 (14, 18), P < 0.01], and the arterial partial pressure of carbon dioxide (PaCO 2) was significantly lower than that of the control group [mmHg (1 mmHg ≈ 0.133 kPa): 66.00 (62.00, 70.00) vs. 68.00 (67.50, 70.05), P < 0.05]. However, there were no significant differences in protein intake, incidence of abnormal electrolyte metabolism, and incidence of endotracheal intubation due to acute respiratory failure between the two groups. Conclusion:The information-guided ENAD treatment process can enable the COPD patients undergoing continuous non-invasive assisted ventilation who experience ENAD to receive earlier cessation of diarrhea, and improve the protein energy metabolism and respiratory function of the patients.

Objective:To evaluate the accuracy of the optical surface imaging system (OSI) using stereotactic radiosurgery (SRS) algorithm in single-center non-coplanar treatment of multiple brain metastases.Methods:Data of phantom and 15 patients with multiple brain metastases who underwent single-center non-coplanar radiotherapy in West China Hospital of Sichuan University from February to April 2022 were retrospectively analyzed. kV/MV and OSI imaging were used for imaging of the patients and phantoms under the same non-coplanar couch angle, respectively. The accuracy of OSI imaging of the phantoms and patients was evaluated using kV/MV imaging as reference image. The difference between the OSI and kV/MV systems is defined as accuracy, and the percentage of the absolute difference ≤1.00 mm in the translational direction or ≤0.50° in the rotational direction is defined as the threshold pass rate. Origin software was used to draw radar maps and Bland-Altman plots for statistical analysis.Results:When OSI images were used for the phantom imaging, the average differences in six-dimensional directions of lateral, long, vertical, rotational, roll and pitch were 0.03 mm, -0.09 mm, -0.27 mm, 0.04°, 0.17° and -0.19°, respectively. The maximum values were -2.20 mm, -2.30 mm, -1.20 mm, 0.60°, -1.00°, and -1.00°, respectively. When OSI system was utilized for the imaging of 15 patients, the average differences in six-dimensional directions were 0.44 mm, 0.16 mm, -0.20 mm, -0.11°, 0.10°, and -0.12°, respectively. The maximum values were -1.80 mm, 2.00 mm, 0.90 mm, -0.90°, -0.70°, and 0.80°, respectively. The translational errors mainly occurred in the lateral and long directions. The qualified rates of the threshold values of the phantoms and patients were 77% and 75% in the lateral direction, 82% and 89% in the long direction, respectively. In addition, 57% and 56% of patients met the threshold conditions of ±1.00 mm and ±0.50° in the six-dimensional directions, respectively.Conclusions:The OSI system using new SRS algorithm cannot meet the high accuracy requirements of single-center non-coplanar radiotherapy for multiple brain metastasis, especially in the lateral and long directions. It is not recommended for non-coplanar image guidance.

Objective To evaluate the efficacy of transurethral resection of bladder tumor(TURBT)in treating cystitis glandularis(CG),and to explore the influencing factors.Methods A retrospective analysis was conducted on 243 CG patients treated with TURBT during Jan.2013 and Dec.2020 in our hospitals.Postoperative efficacy was assessed using global response assessment(GRA).The correlation between GRA score and the demographic characteristics,comorbidities,initial complaints,and postoperative recurrence was determined with logistic regression analysis.Results Among the 243 patients,3.70％(9/243)had dysplasia,2.47％(6/243)had exuberant hyperplasia of Brinell's nest,and 2.06％(5/243)had intestinal metaplasia.The mean GRA score was(2.02±0.72)after a follow-up of(47.10±28.53)months.Re-operation was performed in 10.29％(25/243)of the patients due to recurrence,and the improvement of hydronephrosis and dysuria was 70.59％(12/17)and 50.00％(15/30),respectively.Pelvic fat increase developed in 1 patient(0.41％)after surgery.Logistic regression analysis showed that postoperative GRA score was not significantly correlated with demographic characteristics,body mass index,comorbidities,alcoholism and postoperative recurrence(P＞0.05).Conclusion TURBT is an effective method in the treatment of CG,which can significantly improve patients'hydronephrosis and dysuria.However,approximately 10％of the patients experience recurrence,necessitating further surgery,which suggests the need for vigilance regarding potential recurrence during treatment.

Objective:To compare the clinical effects of acute shortening-lengthening technique with antibiotic calcium sulfate-loaded bone transport technique for the treatment of segmental tibial defects after trauma.Methods:The clinical data of 58 patients with large tibial defects treated by Ilizarov technique in Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from May 2014 to December 2019 were retrospectively analyzed. Thirty patients were treated by acute shortening-lengthening (group A), and they were divided into those who were successful in one-time shortening during operation (group A1) and those who needed gradual shortening after operation (group A2) according to different shortening conditions. And 28 patients by antibiotic calcium sulfate-loaded bone transport (group B). The external fixation time (EFT) and external fixation index (EFI) of the two groups were compared. Bone defect healing and limb functions were evaluated according to the Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria. Complications were compared by Paley classification. The measurement data of normal distribution were expressed as ± s, and t-test was used for comparison between groups; the count data were expressed as n(%), and the chi-square test, Fisher exact probability method or Mann-Whitney U test were used for comparison between groups. Results:Patients were followed for(27.5±5.1)months. There was no significant difference in EFT, EFI, bone defect healing and limb functions between the two groups( P>0.05). The incidence of Grade-Ⅱ[41.2% (7/17)], Grade-Ⅲ [47.1% (8/17)] pin-tract infection in group A1 and Grade-Ⅱ[46.2% (6/13)], Grade-Ⅲ pin-tract [53.8% (7/13)] in group A2 was significantly higher than those in group B[14.3% (4/28)], [17.9% (5/28)] ( P<0.05). The number of complications per capita in group A1 [(1.4±0.3) times/case] and in group A2 [(1.5±0.3) times/case]was significantly higher than that in group B [(1.1±0.5) times/case]. Conclusions:Patients can be cured successfully by both acute shortening-lengthening and bone transport techniques. Compared with acute shortening-lengthening group, the complication incidence in antibiotic calcium sulfate-loaded bone transport group was lower, especially, the infection-related complications. Therefore, antibiotic calcium sulfate-loaded bone transport technique has a greater application prospect in patients with large segmental bone defects caused by infection or osteomyelitis.

Objective:To compare the clinical efficacy between bone transport technique combined with bone grafting plus internal fixation and simple bone transport technique in the treatment of large segmental bone defects at lower limbs after trauma.Methods:A retrospective study was conducted to analyze the clinical data of 42 patients with large segmental bone defects at lower limbs after trauma who had been treated at Department of Trauma Orthopaedics, Honghui Hospital Affiliated to Medicine College, Xi'an Jiaotong University from September 2015 to September 2019. The patients were divided into 2 groups according to the different methods of repairing bone defects. In group A of 18 patients subjected to bone transport combined with bone grafting plus internal fixation, there were 11 males and 7 females with an age of (35.2±10.3) years, and 12 tibial defects and 6 femoral defects; in group B of 24 patients subjected to simple bone transport, there were 15 males and 9 females with an age of (37.3±9.4) years, and 17 tibial defects and 7 femoral defects. The external fixation time (EFT), external fixation index (EFI), total cure time and complications were recorded and compared between the 2 groups. At the last follow-up, the Ennecking score for limb functional recovery (score/total score 30) and Self-rating Anxiety Scale (SAS) were used to evaluate respectively the functional recovery of the limbs and postoperative anxiety.Results:The 2 groups were comparable because there was no significant difference between them in preoperative general data or follow-up time ( P>0.05). There was no statistically significant difference in the number of surgeries between the 2 groups ( P>0.05). The EFT [(5.9±1.5) months], EFI [(0.45±0.09) months/cm], total treatment time [(16.2±2.4) months], Ennecking score for limb functional recovery (87.0%±8.6%), SAS score [(43.2±9.0) points], and complications per capita [(0.4±0.2) times/case] in group A were significantly better than those in group B [(15.3±4.2) months, (1.19±0.28) months/cm, (19.7±3.5) months, (77.3%±9.2%), (58.2±9.3) points, and (1.2±0.5) times/case] (all P<0.05). Conclusion:In the treatment of large segmental bone defects at lower limbs, compared with simple bone transport technique, bone transport technique combined with bone grafting plus internal fixation has advantages of shorter external fixation time and overall cure time, a lower rate of complications, and better functional recovery of the limbs.
