China Pharmacy 2016;27(12):1621-1623
OBJECTIVE:To observe the clinical efficacy and safety of Shuanghuanglian oral liquid combined with cefuroxime axetil in the treatment of bacterial respiratory tract infection. METHODS:184 patients with bacterial respiratory tract infection were randomly divided into test group and control group. Test group was orally given 250 mg Cefuroxime axetil tablet,twice a day+20 ml Shuanghuanglian oral liquid,3 times a day. Control group was only given Cefuroxime axetil tablet (the same dosage as test group). The treatment course for 2 groups was 2 weeks. The cough duration,body temperature recovery time and runny nose disap-pearing time before and after treatment and bacterial clearance rate in 2 groups were observed,clinical efficacy and incidence of ad-verse reactions were recorded. RESULTS:After treatment,the total effective rate in test group was significantly higher than control group,cough duration,body temperature recovery time and runny nose disappearing time were significantly shorter than control group,the differences were statistically significant(P<0.05);and there were no significant differences in the bacterial clearance rate and incidence of adverse reactions(P>0.05). CONCLUSIONS:The efficacy of Shuanghuanglian oral liquid combined with ce-furoxime axetil is superior to cefuroxime axetil alone in the treatment of bacterial respiratory infections,with similar safety.

Objective To investigate the efficacy of micro?surgery for the treatment of medulla oblongata cavernomas. Methods A retrospective analysis was conducted on the clinical data of 21 patients with cavernous hemangioma who received micro?surgical treatment. Of the 21 patients, 13 were men and 8 women,aged 22 to 63 years. The preoperative Karnofsky performance status(KPS)score was 76.5 ± 10.2. The main clinical manifestations included sensory disorder and difficulty swallowing etc. According to the location of the lesions ,the posterior transchoroidal fissure approach was employed for 16 patients;far?lateral approach,5 patients. Electrophysiological monitoring and nervous system navigation were supple?mentarily adopted in both types of surgery. Further ,KPS scoring was conducted to evaluate the patients 'quality of life. Results The medulla cav?ernous hemangioma was excised in all cases. For 17 patients with primary neurological disorders ,their symptoms were alleviated or resolved;4 pa?tients had severe symptoms and 8 presented with new clinical symptoms. A follow?up visit was conducted 8 to 97 months post?surgery(average 47.6 months). All patients were found capable of caring for themselves in daily life and performing simple or normal learning and working activities without recurrence or bleeding. The mean postoperative KPS score was 83.7 ± 15.5. Conclusion Patients with medulla cavernous hemangioma bleeding or severe symptoms should actively seek surgical treatment. Repeated bleeding is the absolute indication for surgery. Surgical skills ,elec?trophysiological monitoring,and nervous system navigation can reduce nervous system damage and protect the brainstem. The patient's quality of life is expected to significantly improve after surgery.

Objective:To investigate the efficacy and safety of cortical-sparing adrenalectomy (CSA) in the treatment of bilateral pheochromocytoma.Methods:The clinical data of 20 patients with bilateral pheochromocytoma treated in Xiangya Hospital of Central South University from January 2004 to December 2019 were analyzed retrospectively, including 10 males and 10 females. The average age of onset was 32.5 (8-51) years. 3 cases had a family history of pheochromocytoma. There were 14 and 6 patients with bilateral synchronous and metachronous onset, respectively. The mean value of vanilmandelic acid (VMA) in 20 cases was (106.4 ± 60.0) μ mol/24h. Preoperative enhanced CT showed a soft tissue mass with uneven enhancement in the adrenal region, with low-density necrosis, which suggested the diagnosis of Pheochromocytoma. All 20 cases underwent CSA under general anesthesia. In 14 cases of bilateral synchronous disease, 9 cases underwent simultaneous operation and 5 cases underwent staged operation; 6 patients with metachronous disease underwent bilateral tumor resection successively. Laparoscopic surgery was performed in 18 cases and open surgery in 2 cases. Through the abdominal or retroperitoneal approach, open the fat capsule around the upper pole of the kidney, free the medial edge of the upper pole of the kidney, expose the adrenal gland and tumor, completely remove the tumor and capsule, ensure that the adrenal tissue is 3-5 mm away from the cutting edge of the tumor, and the reserved cortical size is at least 1 / 3 of the ipsilateral adrenal gland. The central adrenal vein was preserved as much as possible to reduce the damage to the adrenal vascular bed. The operation related data, intraoperative monitoring records, postoperative complications and long-term follow-up results were recorded.Results:All the 20 cases were successfully completed without tumor rupture. The operation time of simultaneous operation and staged operation were (242.3 ± 61.0) min and (137.9 ± 60.3) min, respectively. The number of patients admitted to ICU after operation was 7 and 2, respectively ( P<0.05); The intraoperative bleeding volume was (528.6 ± 355.7) ml and (277.8 ± 264.7) ml, the number of blood transfusion cases were 5 and 2 cases, and the average hospital stay was (7.4 ± 2.0) d and (7.8 ± 3.3) d, respectively ( P>0.05). 20 cases took glucocorticoid orally (prednisone 5 mg, once every 12 hours) after operation. There was no obvious manifestation of adrenocortical dysfunction and Addison's crisis. The hormone was stopped gradually from 2 weeks to 1 month after operation. The average follow-up was 5.4 (1.0-16.0) years. There were 3 cases of recurrence and no metastasis. Gene detection was performed in 10 cases after operation, and 7 cases carried pheochromocytoma RET and VHL pathogenic gene mutations (RET in 2 cases and VHL in 5 cases). Conclusion:Although CSA has a certain risk of recurrence, it avoids hormone replacement and does not increase the risk of metastasis and death. It is recommended for the treatment of hereditary pheochromocytoma, especially bilateral pheochromocytoma.

Objective:To investigate the application value of modified through-suture T-tube in laparoscopic biliary tract surgery.Methods:The retrospective and descriptive study was constructed. The clinical data of 15 patients with cholecystolithiasis and choledocholithiasis who underwent laparoscopic biliary tract surgery in China-Japan Friendship Hospital of Jilin University from January to December 2022 were collected. There were 8 males and 7 females, aged (49± 14)years. Of 15 patients, 8 cases undergoing laparoscopic cholecystectomy + common bile duct exploration and lithotomy+conventional T-tube drainage were set as conventional group and 7 cases undergoing laparoscopic cholecystectomy + common bile duct exploration and lithotomy+modified through-suture T-tube drainage were set as modified group. Observation indicators: (1) intraoperative and postoperative conditions; (2) follow-up. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was conducted using the t test. Count data were described as absolute numbers, and comparison between groups was conducted using Fisher exact probability. Results:(1) Intraoperative and postoperative conditions. Both groups of patients successfully completed the operation, with postoperative vital signs as stable, and no discomfort symptoms. There was no significant difference in duration of postoperative hospital stay between the coventional group and the modified group ( P>0.05). (2) Follow-up. Both groups of patients completed 30 days of postoperative outpatient follow-up. There was a significant difference in the sinus wall thickness between the coventional group and the modified group ( P<0.05). Among the 8 patie-nts in the conventional group, T tube was removed in the first 2 cases of patients after T tube angio-graphy 30 days after operation, and biliary fistula occurred in 1 of them and the drainage tube was re-indurated. For the other 6 cases, the time of T tube retention was extended to 6 weeks after surgery. After T tube angiography, the T tube was removed and no biliary fistula occurred. Among the 7 patients in the modified group, 2 cases with residual choledocholithiasis were found by T tube angiography 30 days after operation. After removal of T tube, percutaneous choledochoscopy was performed, in which the sinus wall was well formed and stone removal was smooth. The other 5 pati-ents were confirmed no residual calculi by T-tube angiography, and then the T-tube was removed, with no biliary fistula. Conclusion:Modified through-suture T-tube can be used in laparoscopic biliary tract surgery.

Objective:To explore the changes of dynamic cerebral autoregulation ability in pilots exposed to acute positive acceleration(+ Gz) by transcranial Doppler combined with beat-to-beat blood pressure.Methods:A total of 26 pilots enrolled in the + 8Gz manned centrifuge trial at the Air Force Medical Center, Air Force Medical University from June to October 2022 were prospectively included. Blood pressure and heart rate were monitored in the resting state before the trial and within 5 min after centrifugation. Transcranial Doppler combined with noninvasive continuous beat-to-beat blood pressure monitor were used to detect bilateral middle cerebral artery blood flow velocity and beat-to-beat pulse pressure respectively. The transfer function analysis was applied to derive the parameters of cerebral blood flow autoregulation in each frequency band from 0.02 to 0.50 Hz, and the phase, gain and coherence were calculated. The above parameters were compared between resting state and after acute + 8Gz positive acceleration exposure.Results:Compared with the resting state, in all of the 26 pilots after acute + 8Gz positive acceleration exposure, the systolic and diastolic blood pressure and heart rate increased significantly ( P<0.001), the phase significantly increased and the gain significantly decreased in the ultra-low frequency band (0.02-0.07 Hz) ( P<0.05); whereas there were no statistical differences of gain and phase in the low frequency band (0.07-0.20 Hz) and the high frequency band (0.20-0.50 Hz) (all P>0.05). Conclusions:Transcranial Doppler combined with beat-to-beat pulse pressure can be used for the assessment of changes in immediate dynamic cerebral autoregulation after acute + Gz exposure, and transfer function analysis of ultra-low frequency band parameters is suitable for this type of evaluation.

Objective:To investigate the correlation between paraspinal muscle atrophy, morphological changes of facet joints and adjacent segment disease (ASDis) after lumbar fusion operation.Methods:A retrospective study was conducted among 195 patients who underwent posterior lumbar fusion again for ASDis at this institution from January 2014 to December 2020, including 29 patients with ASDis whose initial surgical fusion segment was L 4,5. According to Roussouly's staging, there were 5 cases of type I, 9 cases of type II, 10 cases of type III, and 5 cases of type IV. Another 29 cases were selected from patients without ASDis after lumbar fusion as a control group. The control group was paired 1∶1 with the ASDis group according to gender, fusion segment, and Roussouly typing of the lumbar spine. The cross-sectional area (CSA) and fat infiltration (FI) of paravertebral muscle, facet joint angle (F-J) and pedicle facet (P-F) angle before the first (second) operation were measured and compared between the two groups. Then logistic regression analysis was used to determine the predictors of ASDis after posterior lumbar fusion. Finally, the receiver operation characteristic (ROC) curve was described, and the area under the curve (AUC) and cut-off point were calculated. At the same time, the paraspinal muscle atrophy before the second operation in ASDis group was measured. Results:The average follow-up time of 98 patients was 59.25±6.38 months (range, 49-73 months). The average body mass index (BMI) of ASDis group was 24.76±3.64 kg/m 2, which was higher than that in control group (22.24±2.92 kg/m 2) ( t=2.481, P=0.041). The average CSA and relative cross-sectional area (rCSA) of paraspinal muscle in ASDis group were 3 214.32± 421.15 mm 2 and 1.69±0.36 respectively, which were less than 3 978.91±459.87 mm 2 and 2.26±0.29 in control group ( t=10.22, P=0.012; t=9.47, P=0.038). The FI degree of paraspinal muscle in ASDis group (21.95%±5.89%) was significantly higher than that in control group (14.64%±7.11%) ( t=7.32, P=0.002). The F-J angle in ASDis group was 35.06°±3.45°, which was less than 38.39°±4.67° in control group ( t=4.76, P=0.027). The P-F angle in ASDis group was 117.39°±8.13°, which was greater than 111.32°±4.78° in control group ( t=5.25, P=0.031). Multivariate logistic regression analysis showed that higher BMI ( OR=1.34, P=0.038), smaller rCSA of paraspinal muscle ( OR=0.02, P=0.017) and higher FI of paraspinal muscle ( OR=1.58, P=0.032) were the risk factors of postoperative ASDis. The ROC curve showed that the AUC of BMI was 0.680 and the cut-off point was 22.58 kg/m 2; The AUC of the FI of paraspinal muscle was 0.716 and the cut-off point was 15.69%; The AUC of rCSA of paraspinal muscle was 0.227 and the cut-off point was 1.92. For ASDis patients, the paraspinal muscle before the second operation had a higher degree of FI (25.47%±6.59% vs. 21.95%±5.89%, t=3.99, P=0.042) and a smaller rCSA (1.52±0.28 vs. 1.69±0.36, t=3.85, P=0.038) than that before the first operation. The difference between the FI degree of paraspinal muscle before the second operation and the first operation was negatively correlated with the occurrence time of ASDis ( r=-0.53, P=0.039) , and the difference of rCSA was positively correlated with the occurrence time of ASDis ( r=0.64, P=0.043) . Conclusion:When BMI >22.58 kg/m 2, FI of paraspinal muscle >15.69%, and rCSA of paraspinal muscle <1.92, it suggests that ASDis is more likely to occur after operation. And the more obvious paraspinal muscle atrophy after the first operation, the earlier ASDis may occur. Morphological changes of facet joints cannot be used as an index to predict the occurrence of ASDis.

Objective:
To investigate the effects CXCL1 derived from TAMs on the progression of HCC by CXCL1 in tumor microenvironment (TME) .
Methods :
PMA induced human monocyte (THP-1) to obtain undifferentiated macrophages (M0) and then co-cultured with Huh 7 HCC cells.The biomarkers of macrophage phenotype and mRNA level of HCC were analysed by qRT-PCR. Colony formation assay,cell viability assay and transwell assay were performed to evaluate the biological alteration of HCC cells in TME.Epithelial-mesenchymal transition (EMT) molecular genetics were detected using western blot.The levels of CXCL1 in TME were measured by ELISA assay.
Results :
High CXCL1 expression in HCC patients predicted poor prognosis.Abundant macrophages were found in CXCL1 high expression HCC tissues.In macrophages and HCC co-cultured model,significantly increasing CXCL1 expression was detected in both two cells and the biomarkers of M2 macrophages,CD163 and CD206 were elevated.The growth and migration of HCC cells were promoted.
Conclusion
Co-culture of macrophages with HCC cells induces macrophages pro-tumor phenotype and CXCL1 secretion which promotes the progression of HCC.

We aim to screen out the active components that may have therapeutic effect on coronavirus disease 2019 (COVID-19) from the severe and critical cases' prescriptions in the "Coronavirus Disease 2019 Diagnosis and Treatment Plan (Trial Ninth Edition)" issued by the National Health Commission of the People's Republic of China and explain its mechanism through the interactions with proteins. The ETCM database and SwissADME database were used to screen the active components contained in 25 traditional Chinese medicines in 3 prescriptions, and the PDB database was used to obtain the crystal structures of 4 proteins of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Molecular docking was performed using Autodock Vina and molecular dynamics simulations were performed using GROMACS. Binding energy results showed that 44 active ingredients including xambioona, gancaonin L, cynaroside, and baicalin showed good binding affinity with multiple targets of SARS-CoV-2, while molecular dynamics simulations analysis showed that xambioona bound more tightly to the nucleocapsid protein of SARS-CoV-2 and exerted a potent inhibitory effect. Modern technical methods are used to study the active components of traditional Chinese medicine and show that xambioona is an effective inhibitor of SARS-CoV-2 nucleocapsid protein, which provides a theoretical basis for the development of new anti-SARS-CoV-2 drugs and their treatment methods.

Ferroptosis is a type of iron-dependent cell death driven by lipid peroxidation, and its mechanism is associated with iron homeostasis imbalance, lipid peroxidation, and slC7A11-GSH-GPX4 antioxidant system. Ferroptosis plays a key role in the development and progression of nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH), and inhibition of ferroptosis can almost completely inhibit the development of NASH. This article reviews the research advances in the mechanism of ferroptosis and its role in NAFLD/NASH and proposes the research strategies and technical means for ferroptosis, so as to provide a reference for research on the mechanism of NAFLD/NASH.
