Objective To explore the correlation between polarization status of microglia/macrophages(MG/MP)in brain tissue and edema around hematoma in patients with acute cerebral hemorrhage.Methods A total of 52 patients with acute intracerebral hemorrhage admitted to Anyang People's Hospital from December 2020 to November 2022 were selected as the research subjects.All patients underwent craniotomy to remove hematoma,and the normal brain tissue in the cortical area that was not invaded by the hematoma and the fragmented brain tissue around the hematoma(brain tissue around the hematoma)on the surgical pathway were obtained.The expression levels of inflammatory factors such as interleukin(IL)-1β,IL-6,tumor necrosis factor-α(TNF-α),IL-10 and transforming growth factor-β(TGF-β)protein in brain tissue were detected by Western blot.The expression levels of IL-1 β,IL-6,TNF-α,IL-10 and TGF-β mRNA in brain tissue were detected by fluorescence quantitative polymerase chain reaction.The levels of M1-type and M2-type MG/MP in brain tissue was detected by immunofluorescence confocal technique.CT images data of patients before operation were collected and the relative-erihema-tomal edema(r-PHE)was calculated.The patients were divided into high r-PHE group(2.0≤ r-PHE＜2.5)and low r-PHE group(1.5＜r-PHE＜2.0)according to r-PHE.The relative expression of IL-1 β,IL-6,TNF-α,IL-10 and TGF-β mRNA in brain tissue around the hematoma of patients between the high r-PHE group and the low r-PHE group was compared.Results The relative expressions of IL-1 β,IL-6,TNF-α protein and mRNA in brain tissue around the hematoma were significantly higher than those in the normal brain tissues(P＜0.05),but there was no significant difference in the relative expressions of IL-10 and TGF-β protein and mRNA between the brain tissue around the hematoma and the normal brain tissue(P＞0.05).The levels of M1 type and M2 type MG/MP in the brain tissue around the hematoma were significantly higher than those in normal brain tissue(P＜0.05).The relative expressions of IL-1β,IL-6 and TNF-α mRNA in the brain tissue around the hematoma of patients in the high r-PHE group were significantly higher than those in the low r-PHE group(P＜0.05),and there was no significant difference in the relative expressions of TGF-β and IL-10 mRNA in the brain tissue around the hematoma of patients between the two groups(P＞0.05).Conclusion The levels of pro-inflammatory factors and M1-type MG/MP are increased in the brain tissue around the hematoma in patients with acute cerebral hemorrhage,and the degree of polarization of M1-type MG/MP is consistent with the degree of edema around hematoma after cerebral hemorrhage.

This paper summarized Professor ZHANG Yunling's experience in the treatment of amyotrophic lateral sclerosis （ALS） from emphasis on both spleen and kidney. It is considered that the characteristic of ALS manifested as overlap of atrophy-flaccidity disease and convulsive disease， and the core pathogenesis are the deficiency of spleen and kidney and the inner pathogenic qi. ZHANG advocated that ALS should be treated from tonifying both the spleen and kidney， as strong spleen and kidney led the latent pathogen at peace. Usually applied Huangqi （Astragalus mongholicus）， Baizhu （Atractylodes macrocephala） combined with Taizishen （Pseudostellaria heterophylla）， fried Yiyiren （Coix lacryma-jobi）， Doukou （Myristica fragrans） and Sharen （Wurfbainia villosa） to tonify the middle and replenish qi， ascend lucidity and descend turbidity to invigorate the spleen； Roucongrong （Cistanche deserticola）， Tusizi （Cuscuta chinensis） combined with Shanyao （Dioscorea oppositifolia）， Shanzhuyu （Cornus officinalis） and prepared Dihuang （Rehmannia glutinosa） are used to support the fire and nourish the water， so as to replenish the spleen. The empirical formula regarded invigorateing the spleen and replenishing the kidney as the core therapeutic principle throughout the treatment of the whole process， which aimed at extinguishing inner wind and pacifying latent pathogen when treating the root.

Objective:To evaluate the safety and clinical efficacy of transplanting a muscle flap to treat the postoperative refractory empyema with a bronchopleural fistula.Methods:From July 2015 to December 2019, the clinical data of 15 patients who suffered from postoperative refractory empyema with bronchopleural fistula was retrospectively summarized. There were 13 males and two females with a mean age of 61.7 years. Ten cases had previous posterolateral thoracotomy and four cases underwent minimally invasive surgery. After conservative and endoscopic therapy, a pedicled latissimus dorsi muscle flap, a pectoralis major muscle flap, or a free vastus lateralis myocutaneous flap was harvested from the ipsilateral local thorax or thigh and was transferred to cover the intrathoracic cavity.Results:There was no perioperative death. During a mean follow-up of 14.8 months, one patient was dead, one suffered from a recurrence of refractory empyema, and l3 patients had an uneventful course with no recurrence of refractory empyema and bronchopleural fistula. Postoperative chest computed tomography or magnetic resonance imaging showed the empyema cavity was satisfactorily covered with a pedicle or free muscle flap.Conclusions:Muscle flap transplantation is an effective alternative for treating the postoperative refractory empyema with bronchopleural fistula, which can achieve promising short-medium-term results.

Malignant peripheral nerve sheath tumors(MPNST) of the bladder is a very rare malignant tumor, usually secondary to neurofibromatosis type 1 (NF-1), with a few sporadic cases. This paper reports a case of 70-year-old man with bladder MPNST who underwent transurethral resection. Adjuvant intravesical instillation with gemcitabine was given after surgery, and there was no local recurrence and distant metastasis after 12-month follow-up. This paper also made a corresponding literature review.

Objective: To study the treatment of huge empyema with free vastus lateralis muscle flap. Methods: From May 2015 to December 2015, 3 cases of empyema were treated with free vastus lateralis muscle flaps, (unilateral vastus lateralis muscle flap, n=2; bilateral vastus lateralis muscle flaps with Flow-through technique, n=1). The volumes of defects were 12.4 cm×5.1 cm×6.4 cm, 11.8 cm×6.9 cm×5.6 cm, and 14.4 cm×7.6 cm×9.4 cm, respectively. Result: All flaps was survived after 23-29 months follow-up. The pus cavities were filled well. There was no empyema reoccurred. The patients felt good, without chest distress. The donor site of flap healed well. The function of lower limb was not affected. Conclusions Vastus lateralis muscle can fill the pus cavity of empyema successfully, without the sacrifice of chest shape. Free vastus lateralis muscle flap is an ideal choice to repair large empyema defection. For young patient, bilateral free vastus lateralis muscle flap can be used if the cavity is too large to fill with one flap.

Objective: To investigate the value of four-dimensional echocardiography combined with speckle tracking technique on the assessment of right heart function and prognosis in patients with pulmonary arterial hypertension (PAH). Methods: In this prospective study, 51 patients with PAH diagnosed by right heart catheterization in east hospital and south hospital of Renji hospital affiliated to school of medicine of Shanghai Jiaotong University from September 2015 to July 2017 were enrolled as PAH group from July to November 2017. Meanwhile, 26 healthy volunteers with age and sex matched with pulmonary hypertension patients were recruited as control group. The patients were aged (45.8±15.5) years old in PAH group, and there were 6 males and 45 females. The healthy volunteers were aged (45.4±14.6) years old in control group, and there were 4 males and 22 females. Two-dimensional and four-dimensional echocardiographic images were obtained to measure the structure and function of the right heart. The myocardial strain of each ventricle and atrium was measured by sparkle tracking. The patients in PAH group were followed up from July 2017 to August 2018 to observe the endpoint events including all-cause death, re-hospitalization, and clinical deterioration. Results: There were significant differences in two-dimensional echocardiographic parameters(including tricuspid annular plane systolic excursion (TAPSE), right ventricular area change fraction (FAC), and right ventricular systolic pressure (RVSP)), speckle tracking parameters (including global longitudinal systolic peak strain of left ventricle (LVGLS), global longitudinal systolic peak strain of right ventricle (RVGLS),left atrial reservoir function(LASr), left atrial conduit function (LASc), left atrial pump function (LASp), right atrial reservoir function (RASr), right atrial conduit function (RASc), and right atrial pump function (RASp)), and four-dimensional echocardiographic parameters(including right ventricular end diastolic volume (RVEDV) , right ventricular end systolic volume(RVESV), right ventricular stroke volume(RVSV), right ventricular freewall longitudinal strain(RVLSf), interventricular septum longitudinal strain(IVSLS), right ventricular ejection fraction(RVEF)) between control group and PAH group (all P<0.01 or 0.05).Spearman correlation analysis showed that RVEF was correlated with 6-minute walking distance (r=0.540, P<0.001), B-type natriuretic peptide (r=-0.545,P<0.001), New York Heart Association (NYHA) cardiac function classification(r=-0.583, P<0.001), TAPSE(r=0.595, P<0.001), LVGLS (r=-0.461, P=0.001) ,LASc (r=0.453, P=0.002) ,RASc (r=0.532, P<0.001) ,RVESV (r=-0.418, P=0.004) , RVSV (r=0.351, P=0.017) , and IVSLS (r=-0.450, P=0.002) . Pearson correlation analysis also showed that RVEF was correlated with FAC(r=0.579, P<0.001),RVSP (r=-0.442, P=0.002) ,RVGLS (r=-0.521, P<0.001) , LASr (r=0.483, P=0.001) , RASr (r=0.617, P<0.001) , RASp (r=0.513, P<0.001) , and RVLSf (r=-0.592, P<0.001) .After a follow-up of (10.4±2.7) months, there were 4 all-cause deaths, 5 re-hospitalizations and 5 clinical deterioration. Multivariate Cox regression analysis showed that increased RVEF was independent protective factor for end-point events in PAH patients (HR=0.702, P=0.043), and increased RVSP was independent risk factor for end-point events in PAH patients (HR=1.083, P=0.017). The receiver operating characteristic (ROC) curve showed that RVEF and RVSP could be used to predict the end-point events in PAH patients. The area under the curve (AUC) was 0.835(P=0.001) and 0.820(P=0.001), respectively. Conclusions RVEF measured by four-dimensional echocardiography is correlated with right ventricular function parameters measured by two-dimensional echocardiography and can be used to estimate the prognosis of PAH patients. The right atrial and left atrial function assessed by speckle tracking can also reflect the right ventricular function to a certain extent.

Objective To explore the effects of rehabilitation starting at different stages on the gross motor function of infants with high risk of cerebral palsy.Methods 214 neonates (117 boys and 97 girls) at least 14 days old and with a neonatal behavioral neurological assessment scale (NBNA) score of less than 35 were randomly divided into four groups.They received 2 to 3 weeks of rehabilitation in the hospital,followed by 4 to 6 weeks of family rehabilitation and then another 2 to 3 weeks of hospital rehabilitation.The three groups started this course of treatment at different times:beginning when the babies were not older than 3 months for group Ⅰ,3 to 6 months for group Ⅱ,6 to 12 months for group Ⅲ and 12 to 24 months for group Ⅳ.In each individual case the rehabilitation in hospital was replaced by family rehabilitation only when the baby's overall development was normal or almost normal.Another 63 infants with high risk of cerebral palsy composed group Ⅴ.They received only the family rehabilitation.The rehabilitation in hospital included taking neurotrophic drugs,receiving physical treatment,hand manipulation,kinesiotherapy,cognitive training,conductive education,and using orthoses.Family rehabilitation was implemented by the parents once or twice a day,for 35 to 45 minutes each time following detailed,individualized exercise plans made up jointly by the rehabilitation doctors and therapists.Moreover,a clinical checkup was required every 1 to 2 months.At 3,6,12 and 24 months old,all of the subjects' gross motor ability was quantified using the gross motor function measure (GMFM) scale.The hospital stays and the number of subjects diagnosed with cerebral palsy and motor retardation were recorded.Results At 3 months old,the average GMFM scores of the groups were 5.00± 1.89 for group Ⅰ,6.80± 1.55 for group Ⅱ,8.44±1.26 for group Ⅲ,11.10±1.72 for group Ⅳ and 12.70±1.64 for group Ⅴ,the controls.All of the intergroup differences were significant.At 6 months old the average GMFM scores of groups Ⅰ to Ⅳ were not significantly different,but all were significantly lower than the group Ⅳ average.At 12 months old the average GMFM scores of groups Ⅰ,Ⅱ and Ⅴ were significantly higher than the group Ⅲl and Ⅳ averages.At 24 months old the groups' average scores decreased consistently from Ⅰ to Ⅴ,with significant differences between one group and the next.Group Ⅲ had the longest hospital stays,followed by groups Ⅰ,Ⅱ and Ⅳ.Those inter-group differences were significant except for between groups Ⅰ and Ⅱ.The incidence of cerebral palsy in groups Ⅰ and Ⅱ (38.10％ and 29.79％) was significantly higher than in group Ⅲ (21.62％),Ⅳ (12.00％) or Ⅴ (3.17％).Moreover,the incidence of motor retardation in groups Ⅰ and Ⅱ (7.14％ and 10.64％) was also significantly lower than in group Ⅲ(56.76％),Ⅳ (68.00％) or Ⅴ (36.51％),but the differences between groups Ⅰ and Ⅱ and between groups Ⅲ and Ⅳ were not significant.The incidence of excellent gross motor performance ratings at 24mo decreased significantly from group Ⅰ to group Ⅴ,with all of the inter-group differences significant.Conclusion Early and formal rehabilitation is of great importance for infants with a high risk of cerebral palsy.The earlier formal rehabilitation starts,the better is its effect.

Objectives To investigate the etiology, renal pathology, treatment, and prognosis of children's urinary system injury after hematopoietic stem cell transplantation (HSCT). Methods Clinical data of 81 children with urinary dysfunction after HSCT admitted to the Hematology Department in Children's Hospital of Soochow University were analyzed, and relevant literatures were reviewed. Results In 81 cases (50 males and 31 females), the age ranges from 8 months to 17 years old. Thirty cases (37%) with prerenal injury were recovered after active rehydration and other symptom specific treatment. There were 9 (11.1%) children with renal injury, four cases were given up therapy or transferred to other hospitals, thus lead to an unknown prognosis. Kidney biopsy was performed in the remaining five cases for pathological investigation. After active symptom-speific and etiology-based treatment, serum creatinine and glomerular filtration rate of four cases return to normal. But in the long-term follow-up,one case died of recurrence of primary disease, reinfusion of hematopoietic stem cell combined with renal failure. The remaining 3 patients were with chronic kidney disease (CKD). One case with renal thrombotic microangiopathy was in the chronic dialysis. Postrenal renal injuries were mainly hemorrhagic cystitis (28.4%) and urinary tract infection (16%). After a large dose of rehydration, urine alkalization and anti-infection therapy, they were recovered in the short term with a good prognosis. Conclusions Urinary injury after HSCT is mainly divided into three categories: prerenal, renal and postrenal, in which renal injury is prone to frequent recurrence.

Objective To investigate the association of serum C peptide concentration with the severity and the outcome of diabetic foot ulcer (DFU). Methods The clinical data of 257 inpatients with DFU were collected, including fasting and postprandial 2h C peptide levels and C peptide area under curve (AUCCP ). The patients were followed up on the outcomes of ulcers and death. The associations of serum C peptide concentration with the Wagner degree, infection severity, and healing rate were analyzed. Results The medians of fasting and 2h postprandial serum C peptide as well as AUCCP were 1. 37(0. 02 ~ 9. 00) nmol/ L, 3. 22(0. 02 ~ 29. 61) nmol/ L, and 511. 65 (3. 60 ~ 2 691. 30)nmol·min-1 ·L-1 respectively, which were lower than general levels. The time of follow-up in our study was 2. 8 (1. 0 ~ 5. 1) years. By the end of study, the wound of 75. 88% patients was healed, 3. 5%undergone major amputation, and 23. 74% died. After adjusting for relative factors, there were no significant associations of serum fasting and postprandial C peptide levels and AUCCP with Wagner degree and infection severity (P>0. 05). Cox regression analysis showed that the fasting plasma C peptide and hemoglobin were the independent protective factors for the healing of ulcers; old age, male, higher infection degree, and diabetes family history were their independent risk factors ( all P < 0. 05). Conclusions The lower plasma fasting C peptide concentration in patients with DFU is not correlated with Wagner degree and infection severity, but closely related with healing rate.
