ObjectiveTo explore the effect of Yishen Tongluo prescription on sperm DNA fragmentation index （DFI） and sperm mitochondrial membrane potential （MMP） in patients with asymptomatic idiopathic asthenospermia infertility. MethodsA total of 128 patients with asymptomatic idiopathic asthenospermia were randomly assigned to an experimental group （64 cases） and a control group （64 cases）. The experimental group received Yishen Tongluo prescription， while the control group was treated with Wuzi Yanzongwan combined with L-carnitine oral solution. One treatment course lasted 12 weeks. Spouse pregnancy rate， sperm progressive motility （PR）， total sperm motility （PR+NP）， sperm function （sperm tail hypotonic swelling rate， sperm acrosin activity）， sperm DFI， and sperm MMP were compared between the two groups before and after treatment. Adverse reactions were observed and recorded during the study， and clinical efficacy and safety were systematically evaluated. ResultsA total of 121 patients completed the study， including 61 in the experimental group and 60 in the control group. The spouse pregnancy rate in the experimental group was 14.75% （9/61）， higher than that in the control group at 6.67% （4/60）， though the difference was not statistically significant. Clinical efficacy in the experimental group was superior to that in the control group （P<0.05）. Compared with the results before treatment， sperm PR， PR + NP， sperm tail hypotonic swelling rate， sperm acrosin activity， sperm DFI， and sperm MMP were significantly improved in both groups after treatment （P<0.05）， with greater improvements in the experimental group （P<0.05）. However， there was no significant change in sperm concentration in either group after treatment. During the study， no abnormal safety indicators or significant adverse reactions occurred in either group. ConclusionThe kidney-tonifying and collateral-dredging method shows good clinical efficacy in the treatment of asymptomatic idiopathic asthenospermia infertility. Yishen Tongluo prescription can improve sperm motility， increase spouse pregnancy rate， enhance sperm function， and demonstrates good safety. Its mechanism may be related to reducing sperm DFI and increasing sperm MMP.

ObjectiveTo observe the clinical efficacy of herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of infertility induced by idiopathic asthenozoospermia （iAZS） with kidney-Yang deficiency and collateral obstruction syndrome and its effect on sperm DNA damage and superoxide dismutase （SOD） in the seminal plasma. MethodsA total of 112 eligible patients who met the inclusion criteria were randomly divided into an observation group （56 cases） and a control group （56 cases）. The patients in the observation group were treated with herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription，while those in the control group received levocarnitine oral liquid. The primary observation indicators included spouse pregnancy rate，progressive motility （PR），and total sperm motility，and the secondary observation indicators included sperm DNA fragmentation index （DFI），SOD in the seminal plasma， and improvement of TCM syndromes. The treatment cycle was 12 weeks. Before and after treatment，the PR，total sperm motility，sperm DFI，SOD in the seminal plasma， and TCM syndrome scores were recorded. The patients were followed up for 12 weeks and the pregnancy status of spouses within 24 weeks （half a year） was recorded. The clinical efficacy of the two groups was evaluated. ResultThe pregnancy rate of spouses in the observation group was 15.69% （8/51）， higher than 3.85% （2/52） in the control group （χ²=4.118，P<0.05）. The total effective rate of the observation group was 88.24%（45/51）， superior to 69.23% （36/52）in the control group （Z=-3.402，P<0.01）. After treatment， PR， total sperm motility，sperm DFI， SOD in the seminal plasma， and TCM syndromes of the two groups were improved compared with those before treatment （P<0.05）， and the observation group was superior to the control group （P<0.05）. ConclusionHerb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of iAZS-induced infertility patients with kidney-Yang deficiency and collateral obstruction syndrome can increase PR，total sperm motility， and SOD level in the seminal plasma， reduce sperm DFI，improve the TCM symptoms of patients， and improve the pregnancy rate of spouses. The mechanism may be attributed to the fact that this treatment can increase the SOD level in the seminal plasma of patients，enhance the body's antioxidant function，protect sperm from oxidative stress damage，and reduce sperm DFI.

Objective:To investigate the value of Breast Ultrasound Report and Data System (BI-RADS) classification in diagnosis of special types of breast cancer.Methods:A total of 112 patients with special type of breast cancer (112 breast lesions) confirmed by pathology were analyzed by using BI-RADS ultrasound category in the Second Affiliated Hospital, Zhejiang University School of Medicine from August 2009 to August 2020. All patients underwent ultrasound before surgery. The breast lesions were evaluated by senior attending and junior resident according to BI-RADS ultrasound category respectively. Taking histopathological result as the gold standard, the sensitivity and accuracy of BI-RADS classification in the diagnosis of special types of breast cancer were calculated.The differences between different special types of breast cancer in terms of ultrasound characteristics and pathological features were analyzed. Kappa consistency test was used to evaluated the consistency of the results of two physicians.Results:In the 112 patients, pathological results showed that there were 20 cases of metaplastic carcinoma, 19 cases of invasive carcinoma with medullary features, 16 cases of differentiated carcinoma of apocrine gland, 12 cases of mucinous carcinoma, 12 cases of invasive micropapillary carcinoma, 10 cases of invasive papillary carcinoma, 6 cases of invasive lobular carcinoma and 17 cases of other special types of carcinoma. Among them, 4 cases (3.5%) were BI-RADS 3, 13 cases (11.6%) were BI-RADS 4a, 42 cases (37.5%) were BI-RADS 4b, 47 cases (42.0%) were BI-RADS 4c and 6 cases (5.4%) were BI-RADS 5. The accuracy and sensitivity of BI-RADS classification in diagnosis of special types of breast cancer was 96.43% and 96.43%, respectively. There was significant difference in BI-RADS grade among different special types of breast cancer ( P<0.05). Most lesions were characterized by hypoechoic with irregular shape and angular or microlobulated margin. The nodule size, boundary, echo and posterior echo in breast cancer with different special types showed significant differences (all P<0.05). There was a good consistency between the two physicians (Kappa=0.789). Conclusions:The ultrasonography features of different special types of breast cancer are different. BI-RADS classification has great value in diagnosis of special types of breast cancer.

Background:In the clinical setting, the effect of intra-abdominal hypertension on the human body is dependent on time, but its role is not yet clear.Objective:To investigate the effect of the duration of intra-abdominal hypertension (IAH) on the prognosis of critically ill patients.Methods:This prospective cohort study enrolled 256 IAH patients who were admitted to the Surgical ICU of 10 Grade A hospitals in Fujian Province from January 2018 to December 2020. The duration of IAH (DIAH) was obtained after monitoring IAP, and ICU length of stay, duration of mechanical ventilation, duration of continuous renal replacement therapy (CRRT) and average daily energy intake from enteral nutrition during ICU stay were observed and recorded. The correlation was analyzed by Spearman rank correlation. The patients were divided into the survival group and the death group according to their survival state at 60 days after enrollment. Thereafter, clinical characteristics between the two groups were compared. Multivariable logistic regression was used to study and validate the relationship between DIAH and 60-day mortality. The receiver operating characteristics (ROC) curve was established to evaluate the predictive abilities of DIAH on the mortality risk.Results:In critically ill patients, DIAH was positively correlated with duration of mechanical ventilation ( r=0.679, P<0.001), duration of CRRT ( r=0.541, P<0.001) and ICU length of stay ( r=0.794, P<0.001), respectively. In addition, there was a negative correlation between DIAH and average daily energy intake from enteral nutrition ( r=-0.669, P<0.001). After multivariable adjustment, DIAH was an independent risk factor for 60-day mortality in critically patients with IAH ( OR=1.05, 95% CI: 1.01-1.12; P = 0.012), and exhibited a linearity change trend relationship with mortality risk. The ROC curve analysis of DIAH showed that the area under ROC curve (AUC) was 0.825 (95% CI: 0.763~0.886, P<0.01). When the cut-off value was 16.5 days, the sensitivity was 78.4% and the specificity was 75.4%. Conclusions:DIAH is an important risk factor for prognosis in critically ill patients. Early identification and rapid intervention for the etiology of IAH should be performed to shorten DIAH.

Objective:To investigate the clinical efficacy and prognostic influencing factors of open abdomen technique for acute pancreatitis with abdominal compartment syndrome (ACS).Methods:The retrospective cohort study was conducted. The clinical data of 186 patients of acute pancreatitis with ACS who were admitted to 6 hospitals, including 65 cases in the 910th Hospital of Joint Logistics Support Force of Chinese People′s Liberation Army, 46 cases in the First Affiliated Hospital of Wenzhou Medical University, 33 cases in the Fujian Provincial Hospital, 31 cases in the Second Affiliated Hospital of Fujian Medical University, 7 cases in the People′s Hospital Affiliated to Quanzhou Medical College, 4 cases in the Shishi General Hospital, from January 2013 to December 2020 were collected. There were 142 males and 44 females, aged (43±8)years. Observation indica-tors: (1) patients conditions after being treatment with open abdomen technique; (2) analysis of clinical characteristics in patients with different treatment outcomes; (3) changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes; (4) influencing factors for prognosis of patients. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test or the continuity correction chi-square test. Repeated measurement data were analyzed using the repeated ANOVA. Spearman correlation analysis was used for correlation analyses. The COX regression model was used for univariate analysis and COX regression model with forward regression was used for multivariate analysis. Results:(1) Patients conditions after being treatment with open abdomen technique. Intra-abdominal pressure, oxygena-tion index, levels of lactic acid and sequential organ failure score of the 186 patients were (23.3±1.9)mmHg (1 mmHg=0.133 kPa), (121±24)mmHg, (5.0±3.4)mmol/L and 10.4±3.6 before the treatment with open abdomen technique and (11.2±2.9)mmHg, (222±38)mmHg, (3.2±2.1)mmol/L and 4.4±2.3 at postoperative 168 hours, showing significant differences in time effects before and after the treatment ( Ftime=855.26,208.50, 174.91,208.47, P<0.05). (2) Analysis of clinical characteristics in patients with different treatment outcomes. Of the 186 patients, 166 cases survived and were discharged, and 20 cases died during hospitalization. Age, sequential organ failure score, duration of ACS and levels of lactic acid during hospitalization before the treatment with open abdomen technique were (41±7)years, 9.4±3.4, 13(10,21)hours and (4.2±0.6)mmol/L in surviving patients, versus (45±6)years, 11.5±2.4, 65(39,84)hours and (5.2±0.5)mmol/L in dead patients, respectively, showing significant differences between them ( t=-2.10, -2.71, Z=-5.36, t=-7.16, P<0.05). Duration of postoperative acute gastro-intestinal injury, duration of continuous renal replacement therapy, time to liberation from mech-anical ventilation, duration of vasoactive drugs therapy, cases undergoing early abdominal closure, cases without intestinal fistula or with postoperative high-order intestinal fistula and low-order intestinal fistula during hospitalization after the treatment with open abdomen technique were 4(2,6)days, 4(3,7)days, 34(21,41)days, 3(2,6)days, 126, 131, 23, 12 in surviving patients, versus 13(10,17)days, 10(8,18)days, 0(0,3)days, 8(6,12)days, 1, 2, 15, 3 in dead patients, respectively, showing significant differences between them ( Z=-5.60, -3.75, -3.64, -3.06, χ2=41.43, 45.86, P<0.05). (3) Changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes. The volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in surviving patients during hospitalization were (0.29±0.10)mL/(kg·h), (4.2±0.6)mmol/L, 0.0 kcal/(kg·d) and 9.4±3.4 before the treatment with open abdomen technique and (2.22±0.15)mL/(kg·h), (1.9±0.7)mmol/L, (20.7±2.9)kcal/(kg·d) and 3.7±2.2 at postoperative 168 hours. The above indicators in dead patients during hospitalization were (0.28±0.08)mL/(kg·h), (5.2±0.5)mmol/L, 0.0kcal/(kg·d) and 11.5±2.4 before the treatment with open abdomen technique and (0.28±0.09)mL/(kg·h), (7.7±0.8)mmol/L, (4.6±1.8)kcal/(kg·d) and 12.4±2.1 at postoperative 168 hours. There were significant differences in time effects in the above indicators in surviving patients and dead patients before and after the treatment with open abdomen technique ( Ftime=425.57, 188.59, 394.84, 37.52, P<0.05). There were interactive effects between the above indicators and the treatment outcome at different time points ( Finteraction=383.14, 233.04, 169.83, 36.61, P<0.05). There were signifi-cant differences in the change trends of the above indicators between the surviving patients and the dead patients during hospitalization ( Fgouprs=2 739.56, 877.98, 542.05, 240.85, P<0.05). (4) Influen-cing factors for prognosis of patients. Results of univariate analysis showed that age, sequential organ failure score, duration of ACS before surgery, procalcitonin, lactic acid, postoperative high-order intestinal fistula, abdominal hemorrhage, duration of postoperative acute gastrointestinal injury, duration of continuous renal replacement therapy, duration of vasoactive drugs therapy, early abdominal closure were related factors influencing prognosis of patients under-going treatment with open abdomen technique ( hazard ratio=1.07, 1.18, 1.39, 1.16, 8.25, 12.26, 2.83, 1.29, 1.56, 1.41, 0.02, 95% confidence interval as 1.00-1.15, 1.45-2.27, 1.22-1.57, 1.02-1.32, 1.75-38.90, 7.37-41.23, 1.16-6.93, 1.22-1.37, 1.23-1.99, 1.08-1.84, 0.00-0.16, P<0.05). Results of multivariate analysis showed that extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury were independent risk factors influencing prognosis of patients undergoing treatment with open abdomen technique ( hazard ratio=1.05, 7.95, 1.17, 95% confidence interval as 1.01-1.32, 2.05-30.87, 1.13-1.95, P<0.05) and early abdominal closure was an independent protective factor ( hazard ratio=0.10, 95% confidence interval as 0.01-0.89, P<0.05). Results of Spearman correlation analysis showed that duration of ACS was positively correlated with sequential organ failure score before surgery ( r=0.71, P<0.05). Conclusions:Open abdomen technique is effective for acute pancreatitis with ACS. Extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury are independent risk factors for prognosis of patients during hospitalization and early abdominal closure is an independent protective factor.

Objective:To investigate high mobility group protein 1(HMGB1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)levels and their clinical significance in elderly patients with viral pneumonia.Methods:One hundred and sixty elderly patients with viral pneumonia admitted to the Sixth Hospital Affiliated to Anhui Medical University were enrolled as research subjects.In addition, 40 elderly people who underwent regular physical examination were considered as the control group.Patients with viral pneumonia were divided into the low-risk group, middle-risk group and high-risk group according to CURB-65 scores and pneumonia severity index(PSI)scores.HMGB1, TNF-α and IL-6 levels were compared between different groups.The correlations of CURB-65 scores and PSI scores with HMGB1, TNF-α, IL-6 levels were analyzed.Multivariate Logistic regression analysis was used to examine influencing factors for the severity of viral pneumonia in elderly patients.Results:HMGB1, TNF-α and IL-6 levels were higher in research subjects than in the control group.As the severity of viral pneumonia increased, so did HMGB1, TNF-α and IL-6 levels(all P<0.05). HMGB1, TNF-α and IL-6 levels in the severe viral pneumonia group were significantly higher than those in the non-severe viral pneumonia group( P<0.05). HMGB1, TNF-α and IL-6 levels were positively correlated with CURB-65 scores and PSI scores(CURB-65 score: r=0.463, 0.392 and 0.497, P=0.015, 0.003 and 0.025; PSI score: r=0.596, 0.515 and 0.381, P=0.007, 0.011 and 0.009). HMGB1, TNF-α and IL-6 levels were influencing factors for the severity of viral pneumonia in elderly patients( OR=1.344, 1.422 and 1.351, P=0.006, 0.015 and 0.009). Conclusions:HMGB1, TNF-α and IL-6 levels are closely correlated with the severity of viral pneumonia and are helpful for early assessment of viral pneumonia.

Objective:To evaluate the effect of propofol on dopaminergic neurons of mice with Parkinson′s disease (PD).Methods:Forty-eight pathogen-free healthy male C57BL/6 mice, aged 8-12 weeks, weighing 22-32 g, were divided into 3 groups ( n=16 each) using a random number table method: control group (group C), group PD and propofol group (group Pro). The neurotoxin 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropypridine (MPTP) was intraperitoneally injected for 7 consecutive days in PD and Pro groups, while the equal volume of normal saline was given for 7 consecutive days in group C. At 30 min after intraperitoneal injection of MPTP, propofol 25 mg/kg was intraperitoneally injected in group Pro, while the equal volume of normal saline was given daily in group C and group PD.At day 8 after the end of establishment of the model, gait analysis system experiment and rotarod test were used to record the step distance and retention time.The animals were sacrificed after the behavioral tests, and the brain tissues were removed for the dopamine neuron count in substantia nigra (by immunohistochemistry) and for determination of the expression of alpha-Synuclein (α-Syn) and Tyrosine hydroxylase (TH) in the substantia nigra (by Western blot). Results:Compared with group C, the step distance was significantly decreased, retention time were shortened, the dopamine neuron count in substantia nigra was decreased, the expression of TH was down-regulated, and expression of α-Syn in substantia nigra was up-regulated in group PD ( P<0.05), and no significant change was found in the parameters mentioned above in group Pro ( P>0.05). Compared with group PD, the step distance was significantly increased, retention time were prolonged, the dopamine neuron count in substantia nigra was increased, the expression of TH was up-regulated, and expression of α-Syn in substantia nigra was down-regulated in group Pro ( P<0.05). Conclusion:Propofol has protective effect on dopaminergic neurons of PD mice, and the mechanism may be related to the down-regulation of α-Syn expression in substantia nigra.
