ABSTRACT
OBJECTIVES@#Magnetic resonance diffusion-weighted imaging (DWI) has important clinical value in diagnosis and curative effect evaluation on endometrial carcinoma. How to improve the detection rate of endometrial small lesions by DWI is the research focus of MRI technology. This study aims to analyze the image quality of small field MRI ZOOMit-DWI sequence and conventional single-shot echo-planar imaging (SS-EPI) DWI sequence in the scanning of endometrial carcinoma, and to explore the clinical value of ZOOMit-DWI sequence.@*METHODS@#A total of 37 patients with endometrial carcinoma diagnosed by operation and pathology in the Second Xiangya Hospital of Central South University from July 2019 to May 2021 were collected. All patients were scanned with MRI ZOOMit-DWI sequence and SS-EPI DWI sequence before operation. Two radiologists subjectively evaluated the anatomical details, artifacts, geometric deformation and focus definition of the 2 groups of DWI images. At the same time, the signal intensity were measured and the signal-to-noise ratio (SNR), contrast to noise ratio (CNR), and apparent diffusion coefficient (ADC) of the 2 DWI sequences were calculated for objective evaluation. The differences of subjective score, objective score and ADC value of the 2 DWI sequences were analyzed.@*RESULTS@#The SNR of the ZOOMit-DWI group was significantly higher than that of the SS-EPI DWI group (301.96±141.85 vs 94.66±41.26), and the CNR of the ZOOMit-DWI group was significantly higher than that of the SS-EPI DWI group (185.05±105.45 vs 57.91±31.54, P<0.05). There was no significant difference in noise standard deviation between the ZOOMit-DWI group and the SS-EPI DWI group (P>0.05). The subjective score of anatomical detail and focus definition in the ZOOMit-DWI group was significantly higher than that of the SS-EPI DWI group (both P<0.05). The subjective score of artifacts and geometric deformation of ZOOMit-DWI group was significantly lower than that of the SS-EPI DWI group (both P<0.05). ADC had no significant difference between the ZOOMit-DWI group and the SS-EPI DWI group (P>0.05).@*CONCLUSIONS@#The image quality of ZOOMit-DWI is significantly higher than that of conventional SS-EPI DWI. In the MRI DWI examination of endometrial carcinoma, ZOOMit-DWI can effectively reduce the geometric deformation and artifacts of the image, which is more conducive to clinical diagnosis and treatment.

Objective:To study the use of three-dimensional (3D) visualization in diagnosis and interventional treatment of patients with Budd-Chiari syndrome (BCS) presenting with inferior vena cava obstruction and dangerous collateral branches.Methods:The data of 28 patients with BCS presenting with inferior vena cava obstruction and dangerous collateral branches treated at the Affiliated Hospital of Xuzhou Medical University from September 2018 to January 2021 were retrospectively analyzed. There were 11 males and 17 females with a mean age of 49.0 years. Enhanced MR images of these 28 patients were used to build 3D visualization of inferior vena cava. Anteroposterior and left lateral digital subtraction angiography (DSA) of inferior vena cava were performed. The inferior vena cava of these patients was recanalized under guidance of 3D visualization, and patency of inferior vena cava was determined on follow up.Results:3D visualization of inferior vena cava was successfully constructed in all the 28 patients, and 51 dangerous collateral branches were displayed. One, 2, 3 and 4 dangerous collateral branches were found in 13, 8, 6 and 1 patients, respectively. The average angle between the preoperative planning puncture route and the long axis of the proximal end of inferior vena cava was 22.2°. The orifices and courses of the dangerous collaterals and the shape of inferior vena cava could be clearly displayed on 3D visualization in all the 28 patients (100.0%), which were significantly better than the 6 patients (21.4%) using DSA obtained in the anteroposterior and left lateral positions (χ 2=20.045, P<0.05). The inferior vena cava was successfully recanalized in all the 28 patients without complications. On follow up of these patients for 2 to 30 months (mean 18.4 months), the inferior vena cava was patent in 25 patients. Three patients developed inferior vena cava re-obstruction at 3, 4 and 14 months after interventional treatment, respectively. Conclusion:3D visualization was useful in the diagnosis and interventional treatment of patients with BCS presenting with inferior vena cava obstruction and dangerous collateral branches.

ABSTRACT
Objective:To explore the effect of the surgery concept of rapid rehabilitation on the postoperative rehabilitation, immune function and nutritional status of patients with colorectal cancer undergoing laparoscopic radical surgery.Methods:From June 2017 to June 2019, 106 patients with colorectal cancer underwent laparoscopic radical surgery in the Affiliated Hospital of Shaoxing University of Arts and Sciences were divided into the observation group and the control group according to the random digital table method, with 53 cases in each group.The observation group adopted the surgery concept of rapid rehabilitation, while the control group adopted the surgery concept of conventional rehabilitation.The amount of intraoperative bleeding, postoperative complications and operation time were compared between the two groups.The recovery of gastrointestinal function, the changes of immune function and nutritional indicators were compared between the two groups.Results:There were no statistically significant differences in the amount of bleeding and operation time between the two groups(all P>0.05). The incidence of postoperative complications in the observation group was 5.66%(3/53), which was lower than 24.53%(13/53) in the control group(χ 2=7.361, P<0.05). The time of first anal exhaust[(2.14±0.32)d] and first eating[(1.85±0.42)d]in the observation group were shorter than those in the control group[(3.62±0.61)d and (2.79±0.36)d]( t=15.642, 12.371, all P<0.05). Three days after operation, the CD 3+ [(50.82±2.31)%], CD 4+ [(34.01±2.19)%]and CD 4+/CD 8+ (1.03±0.08) in the observation group were higher than those in the control group[(46.30±2.68)%, (30.26±2.05)% and (0.81±0.12)]( t=9.300, 9.101, 11.105, all P<0.05). The serum transferrin[(1.97±0.14)g/L]and prealbumin[(0.23±0.03)g/L] in the observation group were higher than those in the control group[(1.72±0.15)g/L and (0.18±0.03)g/L]( t=8.870, 8.580, all P<0.05). Conclusion:The surgery concept of rapid rehabilitation can promote the postoperative rehabilitation of patients with colorectal cancer, improve the immune function and nutritional status of patients, and has less complications.
ABSTRACT
Objective:To understand and determine the biological properties of Chlamydia pneumonia (Cpn) hypothetical protein Cpn0423 and the mechanisms of which involved in Cpn0423-induced inflammatory response. Methods:The biological properties of Cpn0423 gene were analyzed using bioinformatic software. The subcellular localization of nucleotide-binding oligomerization domain-like receptor 2 (NOD2) in bone marrow-derived macrophages (BMDMs) was detected by confocal microscope. NOD2-siRNA was used to inhibit the expression of NOD2 at mRNA level. Cpn0423-induced macrophage inflammatory protein 2 (MIP-2) and IL-6 production in BMDMs were detected by ELISA. PCR was performed to detect Cpn0423 DNA in bronchoalveolar lavage fluid (BALF) of Cpn-positive patients.Results:The homology between Cpn0423 and other type Ⅲ secretion system effector proteins of Chlamydia ranged from 85% to 93%. NOD2-siRNA could effectively inhibit the expression of NOD2 at mRNA level in BMDMs ( P<0.001). Moreover, Cpn0423-induced production of MIP-2 [(920.5±99.1) pg/ml vs (130.1±11.5) pg/ml, P<0.001] and IL-6 [(266.2±58.4) pg/ml vs (165.7±21.5) pg/ml, P<0.001] in BMDMs were decreased following NOD2-siRNA pre-treatment. Cpn0423 DNA was detected in the BAlF of 83.3% (10/12) of Cpn-positive cases, but not in Cpn-negative cases. Conclusions:Cpn0423 induced inflammatory response in host cells through NOD2 pathway, which was closely related to the chronic inflammatory injury caused by Cpn.
ABSTRACT
Paraneoplastic neurological syndromes (PNS) are a rare group of immune-mediated disorders that affect the central and peripheral neuromuscular system in association with cancer.If the limbal lobe system of the brain is involved,it will show paraneoplastic limbal encephalitis(PLE).The discern of patients with PNS is challenging since tumors causing paraneoplastic neurologic disorders are often asymptomatic and sometimes occult.We report a case of PLE with double positive anti-Hu and Yo antibodies,and further analyze and discuss it in conmbination with relevant literature to improve the understanding of the disease.
ABSTRACT
Objective To investigate the effect of hepatitis B virus(HBV)infection on serum iron markers in pregnant women.Methods A total of 188 pregnant women with HBV infection and 157 normal pregnant women were recruited in this study.Serum levels of iron,ferritin,transferrin,HBV DNA,alanine aminotrans-ferase(ALT)and aspartate aminotransferase(AST)were measured and compared.Results At the same stage of pregnancy,the serum ferritin level in pregnant women with HBV infection was higher than that of normal pregnant women(Z= -1.72,P=0.04;Z= -2.33,P=0.01;Z= -4.42,P=0.01),while the serum transfer-rin concentration increased in normal pregnant women in the second and third trimesters,and the differences between the two groups were statistically significant(Z= -3.26,P<0.01;Z= -2.25,P=0.01).In pregnant women with HBV infection,the serum ferritin levels in patients with positive results of ALT and AST were higher than those in patients with negative results(ALT:P=0.01;AST:P=0.02),however,there was no change in healthy pregnant women.Conclusion There is iron metabolism imbalance in pregnant women with HBV infection.We should monitor serum iron markers to guide pregnant women for appropriate iron supple-mentation in gestation period.

ABSTRACT
BACKGROUND:Some studies have focused on bone marrow mesenchymalstem cells (BMSCs) combined with allograft bone or artificial bone substitute materials for bonedefect repair. But there is no report on BMSCs combined with Bio-oss for repair of rabbit skull defects as yet.OBJECTIVE:To observe the effect ofBMSCs combined with Bio-oss in repairing skull defects in rabbits.METHODS:BMSCs from male rabbits were isolated, cultured, and used as seed cells. In the skull of the female rabbits,three full-thickness bone defects with the same external diameter of 6 mm were made by a ring bone drill. Ninety-six female rabbits were randomly divided into four groups, and given Bio-oss/BMSCs in combination group, Bio-oss alone in Bio-oss group, BMSCs implantation in BMSCs group, and no intervention in blank group. All the implant surfaces were covered with guided tissue regeneration membrane.RESULTS AND CONCLUSION:The osteogenic effect in the combination group was better than that in the other three groups, and the Bio-oss group showed better osteogenesis in comparison with BMSCs and blank groups. But there was no significant difference between the BMSCs and blank groups. These findings indicate that the combined use of BMSCs as seed cells and Bio-oss as a scaffold material exerts overt osteogenic effects in rabbit skull defect area, which provides a new idea for the clinical treatment of bone defects.
ABSTRACT
BACKGROUND: In clinical, the research on the method and the material of the soft tissue defect of the operation area has been in depth. It wil have a positive impact on our exploration and research in this field through the establishment of reliable experimental animal oral soft tissue defect model. OBJECTIVE: To establish a rabbit model of oral soft tissue defects for oral treatment of soft tissue defects in-depth study. METHODS: Eighteen 3-month-old male New Zealand rabbits were enrol ed. A tissue ring cutting dril of 5 mm diameter was used to prepare round ful -thickness soft tissue defects in the front part of the hard palate and, respectively, from the back of the maxil ary incisors, about 2 mm from the hard palate mucosal edge. Morphology and histology were observed at 3, 7, 14, 21, 28 and 56 days after model establishment. RESULTS AND CONCLUSION: (1) Morphological observation: After 3 and 7 days, the wound’s inflammatory reaction was obvious. As the time goes, the inflammatory response subsided, the wound gradual y healed. Scar formation was observed at 21, 28 and 56 days after surgery. (2) Histological observation: 3 and 7 days after injury, many inflammatory cel s were infiltrating, and tissue necrosis area was larger. At 7 days after surgery, with the extensive formation of connective tissue proliferation and new blood capil aries, the wound gradual y shaping completely. (3) Results indicated that a rabbit model of oral soft tissue defects was successful y established, which was in line with the physical laws of wound healing and the characteristics of human oral soft tissue defects healing.
ABSTRACT
BACKGROUND:In previous experiments, we have confirmed that platelet rich fibrin has the ability of osteoinduction, and have conducted a preliminary study on its microstructure and biomechanics. However, little is reported on its histology research. OBJECTIVE:To compare the histological changes after implanting platelet-rich fibrin, Bio-Oss and autologous bone and to analyze the pros and cons of platelet-rich fibrin implantation for repair of bone defects. METHODS: As previously reported, animal models of critical bone defects were established respectively on the bilateral femoral condyles of 12 beagle dogs. Then, platelet-rich fibrin, Bio-Oss+colagen membrane (Bio-Oss group) and autologous bone (autologous bone group)+colagen membrane were respectively implanted. At 3, 6, 8 and 12 months, one experimental dog from each group was kiled, respectively, and histological observation was performed. Another beagle dog as blank control was enroled to establish the animal model of critical bone defects, with no implantation. RESULTS AND CONCLUSION:At 3, 6, 8 and 12 months after implantation, there were significant differences in the new bone formation speed and amount between the platelet-rich fibrin group, Bio-Oss group and autologous bone group. These three kinds of bone grafts al had osteoinductive ability to different extents. In the platelet-rich fibrin group, the osteogenic effects were better at 3 and 6 months, and the new bone was similar to natural one; in the autologuos bone group, bone necrosis was noticeable at 3 and 6 months, but the osteogenic effects became better at 8 months, and the new bone was similar to natural one at 12 months; in the Bio-oss group, the osteogenic effects were similar to those in the platelet-rich fibrin group, but the residual of Bio-oss was visible at 12 months; in the blank control group, no bone formed at 3 months, indicating the animal model of critical bone defects was made successfuly. In brief, the platelet-rich fibrin has good osteoinductive ability, with shorter time and better quality.
ABSTRACT
BACKGROUND:Insufficient oral soft tissues in the implant zone may have a negative effect on the wound healing and the aesthetic restoration in the late stage. Platelet-rich fibrin can promote the wound healing of soft tissue defects. But there is stil a lack of in-depth studies on the promotion of oral soft tissue defects in animal experiments. OBJECTIVE: To compare the repairing effects of platelet-rich fibrin and colagen membrane on soft tissue defects of the hard palate in New Zealand rabbits. METHODS:Fifty-four New Zealand rabbits were randomly divided into three groups (n=14 per group): platelet-rich fibrin group, colagen membrane group and blank control group. A 5 mm-diameter circular ful-thickness soft tissue defect was made in the front of the hard palate, 2 mm distant to the rear maxilary incisors and mucosal edge of the bilateral hard palates. Autologous platelet-rich fibrin membrane or colagen membrane were implanted into the defect in the platelet-rich fibrin group and colagen membrane group, respectively. No treatment was given in the blank control group. General observation of the wound and wound healing analysis were performed at days 3, 7, 14, 21, 28, 56 post operation. Hematoxylin-eosin staining, CD31 immunohistochemical staining and Masson staining were used to observe inflammatory reaction, angiogenesis and colagen formation in the surgical site. RESULTS AND CONCLUSION:The wound healing rate was fastest in the platelet-rich fibrin group, and no obvious scar formed. At 3 days post operation, there was no difference in the wound healing rates among the three groups; at 7 days, the wound healing rate in the platelet-rich fibrin group was significantly higher than that in the colagen membrane group and blank control group (P < 0.05). At 3 and 7 days after operation, the inflammatory reaction in the platelet-rich fibrin group was less than that in the colagen membrane and blank control groups (P < 0.05); at 14, 21, 28 and 56 days, there was no significant difference between the three groups. At 7, 14, 21 days after operation, the average absorbance value of CD31 in the platelet-rich fibrin group was significantly higher than that in the colagen membrane and blank control groups (P < 0.05). The average absorbance value of colagen formation in the platelet-rich fibrin group was significantly higher than that in the colagen membrane and blank control groups at 7 days after operation (P < 0.05), significantly higher than that in the blank control group at 14 days (P < 0.05), but lower than that in the colagen membrane and blank control groups at 21, 28 and 56 days after operation (P < 0.05). These findings show that platelet-rich fibrin can reduce inflammatory reactions in the process of wound healing, accelerate the angiogenesis, regulate the metabolism of colagen, reduce the formation of scar and improve the quality of wound healing, thereby promoting the repair of oral soft tissue defects.
ABSTRACT
BACKGROUND:Previous studies have found that platelet-rich fibrin has a good ability to induce gingival soft tissue repair and regeneration. OBJECTIVE:To observe the effects of platelet-rich fibrinversus colagen membrane on gingival soft tissue healing, and to evaluate the ability of platelet-rich fibrin to repair gingival defects. METHODS:Twenty-two patients (2 premolar teeth and 20 molars) scheduled for premolar or molar removal or ridge preservation due to various reasons were selected and randomized into two groups. Bio-Oss was implanted into the extraction socket folowed by covering with platelet-rich fibrin or colagen membrane. Healing time and healing rate of gingival defects were detected to evaluate the ability of platelet-rich fibrin to promote gingival tissue healing at 1-2 weeks after Bio-Oss implantation. RESULTS AND CONCLUSION:The healing time was (12.17±2.25) days in the platelet-rich fibrin group and (17.30±2.58) days in the colagen group. The healing rate of the platelet-rich fibrin group was notably higher than that in the colagen membrane group at 1 and 2 weeks after Bio-Oss implantation. These findings indicate that platelet-rich fibrin is better than colagen membrane to improve the healing of gingival soft tissues with a shorter healing time.
ABSTRACT
Objective To evaluate the clinicopathological characteristics of mucinous breast carcinoma (MBC) and its prognosis.Methods 112 cases of MBC treated in Obstetrics and Gynecology Hospital of Fudan University between Jan 2005 and Dec 2014 were enrolled retrospectively together with 1 157cases of invasive ductal carcinoma (IDC) for comparison.There were 71 cases of pure MBC (PMBC) and 41cases of mixed MBC (MMBC).PMBC and MMBC were compared with each other,and were also compared with IDC respectively.Results PMBC had smaller tumor mass,higher expression rate of hormone receptors (all P＜0.05),lower rate of lymph node metastasis (7.0％ vs.40.6％,x2 =32.663,P ＜0.001) when compared with IDC.The 5 year disease free survival (DFS) and overall survival (OS) of PMBC were both better than those of IDC (DFS:94.6％ ±3.0％ vs.81.3％ ± 1.1％,x2 =7.265,P =0.007;OS:92.4％ ±5.3％ vs.88.5％ ± 1.0％,x2 =4.059,P =0.044).MMBC had relatively larger tumor mass,higher expression rate of hormone receptor,but had no difference in the rate of lymph node metastasis (48.8％ vs.40.6％,x2 =3.417,P =0.332) when compared with IDC.There was no statistically significant difference in 5 yearDFSandOSbetweenMMBCandIDC (DFS:79.1％ ±7.1％ vs.81.3％±1.1％,x2 =0.167,P=0.683;OS:84.5％ ±7.2％ vs.88.5％ ± 1.0％,x2 =0.123,P =0.726).PMBC had relatively smaller tumor mass,lower rate of lymph node metastasis,but had no difference in the expression rate of hormone receptors.The 5 year DFS and OS of MMBC were both better than those of MMBC (DFS:94.6％ ± 3.0％ vs.79.1％±7.1％,x2 =6.772,P =0.009;OS:92.4％ ±5.3％ vs.84.5％ ±7.2％,x2 =6.401,P=0.036).Lymph node status was the only statistically significant prognostic factor of MBC by COX multivariate analysis.Conclusions PMBC has better prognosis than MMBC and IDC owing to its lower rate of lymph node metastasis.MMBC has higher rate of node metastasis than PMBC,hence similar prognosis with IDC.
ABSTRACT
Objective To evaluate the prognostic significance of lymph node ratio (LNR) in axillary lymph node positive breast cancer.Methods Eight hundred and three cases axillary lymph node positive breast cancer patients without distant metastasis were systematically treated in the Obstetrics and Gynecology Hospital of Fudan University from 2006 to 2014,at least 10 lymph node removed in each case.Clinicopathological data including 5-year disease-free survival rate (5y-DFSR) and 5-year overall survival rate (5y-OSR) were described.Factors related with prognosis were analyzed by univariate analysis.Prognostic difference was compared among different LNR stage in each axillary lymph node pathological stage(pN).Prognostic significance of pN and LNR was compared by multivariate analysis.Results Mean lymph nodes removed were 15.47±4.70 lymph,and median positive lymph nodes were 4 lymph in 803 cases axillary lymph node positive breast cancer patients.Altogether 159 cases of local recurrence and distant metastasis and 99 cases of breast cancer-related death occurred during median follow-up of 61 months.Five-year DFSR was 77％ and 5y-OSR was 83％.Log-rank univariate analysis showen that pT,pN,LNR,lymphovascular invasion and ER status were related to DFS and OS.Five-year DFSR and OSR for pN1,pN2,pN3 were 89％,68％,59％ and 93％,78％,63％,respectively,whereas 5y-DFSR and 5y-OSR for LNR1,LNR2,LNR3 were 90％,69％,56％ and 94％,80％,57％,respectively.There was statistically significant difference among different LNR in pN1 and pN2 (pN1:DFS:P=0.005,0S:P=0.024;pN2:DFS:P=0.017,0S:P=0.000),but not in pN3,inspite of difference tendency (DFS:P =0.165,OS:P =0.075).In multivariate analysis,when pN or LNR were entered into the Cox regression mode respectively,both were the independent prognostic factors of DFS(P＜0.001) and OS(P＜0.001).When pN and LNR were entered into the Cox hazard regression model at the same time,LNR remained as the independent prognostic factor of DFS and OS (P ＜ 0.001),but pN lost significance (DFS:P =0.461,OS:P=0.162).Conclusion LNR is independent prognostic factor for positive axillary lymph node breast cancer.

ABSTRACT
Magnesium stents have gained increasing interest as an ideal stent of future intervention. In order to study the deformation behavior of magnesium alloy stents in the interventional treatment, the finite element method was used to analysis the effects of different crimp and expansion dimensions on the mechanical properties (maximum stress, radial recoil rate, longitudinal shortening rate and radial strength). The results showed that crimping and expanding have a minimal influence on the stent radial strength. When the expansion size is same, the maximum equivalent stress and recoil rate decrease with the crimp size. When the crimp size is same, in contrast with the radial recoil rate, the maximum equivalent stress and longitudinal shortening rate increase with the expansion size. In addition the paper verified the radial strength-radial displacement curve obtained by FEM. Results are basically consistent, indicating the finite element method can efficiently provide researchers with reliable, high-quality design.

Objective To observe the effects of parecoxib sodium on laparoscopic cholecystectomy ( LC ) patients after remifentanil fast track anesthesia.Methods 120 patients underwent general anesthesia for laparoscopic cholecystectomy were divided into two groups using random number table,60 cases in each group.The observation group was injected parecoxib sodium 40mg+saline solution 5 mL,while the control group was injected only saline so-lution 5mL prior to induction of anesthesia.The heart rate,mean arterial pressure,awaked time,pain score,agitation score and adverse reaction were compared.Results 5, 15, 30min after extubation, heart rate were ( 75.7 ± 4.8)times/min,(79.3 ±6.2)times/min,(74.2 ±5.2)times/min in the observation group and (85.2 ±3.8)times/min, (88.2 ±5.9)times/min,(86.1 ±6.2)times/min in the control group,and the mean arterial pressure were (103.5 ± 11.3)mmHg,(104.7 ±12.6)mmHg,(108.4 ±12.7)mmHg in the observation group and (132.3 ±16.3)mmHg, (135.2 ±14.6) mmHg,(133.6 ±11.8) mmHg in the control group,there were statistifically significant differences (t=4.722,4.357,4.236,4.732,4.367,4.063,all P <0.05).The pain score,agitation score were (2.5 ± 0.9)points,(1.4 ±0.8) points in the observation group,which were lower than (4.2 ±1.2) points,(3.2 ± 1.2)points in the control group(t =4.232,5.234,all P<0.05).Conclusion Parecoxib sodium can reduce the fast-track anesthesia agitation and pain,improve hemodynamics and stress response in LC patients.
ABSTRACT
Objective To investigate the inhibitory effect of baicalein on mycoplasma pneumonia and its the protective mecha -nism in body , and to provide scientific experimental basis for prevention and treatment of mycoplasma pneumoniae infection .Methods The mycoplasma pneumoniae and baicalein treated BALB /c mice lung tissues were stained with hematoxylin eosin (HE), and his-topathological grading .Minimum inhibitory concentration ( MIC) of baicalein on mycoplasma pneumonia was determined by real-time quantitative polymerase chain reaction ( PCR) .The expression of P 1 adhesion molecules mRNA and protein in lung tissue of BALB /c mice was determined with reverse transcription-PCR and Western blot .The expression of epidermal growth factor ( EGF) mRNA and protein in lung tissue was detected by quantitative RT-PCR and immunofluorescence .Results Baicalein significantly reduced the my-coplasma treated mice's lung tissue pathological score .The minimal inhibitory concentration of baicalein was 32 μg/ml.Baicalein sig-nificantly downregulated P 1 gene transcription and protein translation , and upregulated EGF gene transcription and protein expression . Conclusions Baicalein shows significant resistance to mycoplasma pneumoniae , and can protect the body against mycoplasma damage by inhibiting the expression of P 1 protein and promoting the expression of EGF protein .
