Objective:To investigate the efficacy and safety of prednisone combined with standard quadruple antituberculosis therapy (HRZE) in the treatment of tuberculous pleurisy.Methods:A prospective study was conducted involving 120 patients with tuberculous pleurisy who were admitted to the Shaanxi Provincial Tuberculosis Prevention and Control Hospital from February 2021 to February 2023. The patients were randomly assigned to a study group and a control group, with 60 patients in each group, using a computer-generated randomization method. The control group received HRZE alone, while the study group received prednisone therapy and HRZE. The efficacy, clinical indicators, adverse reactions, and serum inflammatory factor levels were compared between the two groups.Results:The total response rate in the study group was significantly higher than that in the control group [93.33% (56/60) vs. 78.33% (47/60), χ2 = 5.55, P < 0.05). In the study group, the time for clinical symptom improvement was (10.34 ± 1.65) days, the time for pleural effusion absorption was (21.37 ± 4.16) days, the pleural thickness measured (2.15 ± 0.35) mm, and the duration of hospitalization was (23.19 ± 4.56) days. They were significantly shorter or smaller than those in the control group [(13.27 ± 2.30) days, (27.25 ± 4.95) days, (2.62 ± 0.40) mm, (28.42 ± 5.60) days, t = 8.02, 7.04, 6.85, 5.61, all P < 0.05]. There was no significant difference in the incidence of adverse reactions between the two groups (χ2 = 2.91, P > 0.05). After 8 weeks of treatment, all serum inflammatory factors improved in both groups compared with baseline levels. In the study group, levels of interleukin-6 [(90.37 ± 12.05) ng/L] and interleukin-18 [(270.94 ± 14.58) ng/L] were significantly lower than those in the control group [(110.59 ± 16.90) ng/L, (296.10 ± 25.29) ng/L, t = 7.55, 6.68, both P < 0.05]. Levels of interleukin-10 [(78.91 ± 8.25) ng/L] and soluble interleukin-2 receptor [(1875.82 ± 359.23) pg/L] in the study group were significantly higher than those in the control group [(70.40 ± 7.16) ng/L, (1566.87 ± 311.02) pg/L, t = -6.03, -5.04, both P < 0.05]. Conclusion:The combination of prednisone and HRZE demonstrates good efficacy and safety, and it is beneficial for improving inflammatory factors.

Based on the current situation and task of fighting COVID-19, and combined with emergency management mode of public health emergencies and participation of multi-times emergency rescue practices along with the case analysis and literature review and brain-storming, we constructed a basic framework of the emergency command system of public health emergencies in COVID-19 epidemic prevention and control background. The framework contained four modules: the response mechanism, the organizational structure, the emergency capacity, and the supervisory mechanism and the advantages and key points in implementing this emergency command system was discussed.

Objective The purpose of the experiment is to research the effects of different kind of anti-platelet drugs and their combinations in prevention of vascular restenosis after ballon-injury, and to evaluate the best way of clinical utility of anti-platelet drugs.Methods Fifty-six male New Zealand White Rabbits were randomly assigned to 3 groups: the control group (ML) , the model group (M) , the experimental group.The experimental group was divided to 5 subgroups, the aspirin group (A), the cilostazol group (B) , the clopidogrel group (C), the aspirin plus cilostazol group (A + B) , and the aspirin plus colopidogrel group (A + C).Femoral artery stenosis model was induced by halloon injury except the control group.The rabbits were fed different drugs 3 days before operation except the normal group and the model group.On the 14th day after operation, the rabbits were sacrificed and the iliofemoral arteries were removed and made to the pathological section.We measured the internal elastic lamina, external elastic lamiua and luminal areas measured.Then calculate the area of intima, media and the ratio of intima vs.media.Results ①There is no endothelium hyperplasia in control group.Compared with the control group, we observed endothelium hyperplasia in both model group and the experimental groups.Compared with the model group, endothelium hyperplasia in all experimental groups is in a lower degree;② Cilostazol alone works better than aspirin alone and clopidogrel alone in prevention of vascular restenosis after ballon-injury.Clopidogrel combined with aspirin and cilostazol combined with aspirin both work better than aspirin alone in prevention of vascular restenosis after ballon-injury.There is no apparent difference between the effect of clopidogrel combined with aspirin and cilostazol combined with aspirin.Conclusions ① Different anti-platelet drugs and different combinations of them can prevent the happening of vascular restenosis after ballon-injury.② Cilostazol works better than aspirin and clopidogrel in prevention the happening of vascular restenosis after ballon-injury, and combination of anti-platelet drugs which contains cilostazol works better than other way of combination of anti-platelet drugs.③ Cilostazol and combination of anti-platelet drugs which contains cilostazol is potential useful in clinical uses to prevent restenosis after PTA.

OBJECTIVETo investigate the safe and effective treatment for painful venous malformation (VM) in limbs.

METHOD(1) 97 cases with painful VM underwent MRI to detect the location of VM, as well as its size and structure, its relationship with the surrounding tissue. Statistical analysis was also performed. (2) The embolic agent (ethanol) was first injected to embolize the draining vessels of VM, then the Polidocanol plus Methotrexate (MTX) was followed to keep the embolization effect on VM. The therapeutic effect was observed and analyzed.

RESULTSFrom January 2010 to January 2012, 97 patients with painful VM were treated. A Spearman correlation analysis showed no significant correlation between symptoms of pain and lesion growth, volume, or MRI grades (P > 0.05). The lesions in the muscle space are more likely to have the symptoms of pain (P < 0.01), followed by the lesions in the muscle, then the lesions in the joint and subcutaneous tissue. The pain relieve percentage was 95.9% (93/97) after one time embolic sclerotherapy. No severe complication, such as distant embolization, nerve damage, or muscle atrophy happened. No pain reoccurrence happened after 0.5-1.5 years of follow-up period.

CONCLUSIONSThe treatment of embolic scleratherapy is minimal invasive, safe and effective for painful VM with stable results.

OBJECTIVETo summarize the management of infant vascular tumors with Kasabach-Merritt phenomenon (KMP) and to evaluate the effect of drug combined with sclerotherapy.

METHODSFrom Feb. 2007 to Nov. 2014, 25 cases with KMP, who underwent drug therapy combined with sclerotherapy, were retrospectively studied. Oral corticosteroids (2 mg/kg per day) was used as the first-line therapy on all of the patients and intravenous vincristine (1.5 mg/m2 every week) was added when the platelet counts didn't recover obviously after 2-3 weeks. After the recovery of the platelet counts, the patients were admitted for sclerotherapy (average, 4.56 sessions per case) with 100% alcohol (1-3 ml per session), Lauromacrogol (1.25-5 ml per session) and betamethasone (0.25-1 ml per session). All the patients were followed up for 42 months ( range, 9 months to 6.5 years). Therapeutic outcomes were assessed by evaluating platelet counts, size of lesion, function of trunk and limb.

RESULTSAll the 25 cases got obvious recovery in the platelet counts [average, (94.3 ± 18.5) x 10(9)/L] after drug therapy, of which 16 were treated by single oral corticosteroids for 4-7 weeks and 9 were treated by corticosteroids plus intravenous vincristine for 2-5 weeks. Meantime, 11 cases received platelet transfusions, of which 3 were coupled with gamma globulin intramuscularly. During the first admission, each of the 25 cases received 1-4 sessions of sclerotherapy (average, 2.6 sessions each case). One week after the sclerotherapy, the platelet counts returned to (167-312) x 10(9)/L (average, (258.5 ± 34.4) x 10(9)/L). The hemoglobin and blood coagulation function returned to normal within 1-5 weeks. Meanwhile the mental condition, appetite, body weight, sleeping were greatly improved. The size of the lesions decreased gradually after the combined therapy including 13 cases within 3-12 months and 13 cases within 13-36 months. Long term follow-up indicated that only 1 case need treatment for recurrent decrease of platelet counts, and all of the 25 cases kept the normal weight, height, immunity as well as the growing development.

CONCLUSIONSOral corticosteroids plus intravenous vincristine combined with sclerotherapy is a reliable management with high cure rate, short course and minor side-effect.

Objective To investigate the feasibility of a noval anterior cubital approach for the coronoid via flexor?prona?tor teres interval and assess the clinical result. Methods Five formalin?fixed adult cadaver elbows were used. Through a single universal anteromedial longitudinal skin incision, the coronoid tip was exposed via pronator and flexor carpiradialis interval, and coronoid anteromedial facet and base via palm longus and flexor carpi ulnaris interval. The distances from the entry point to the muscles or branching point of the nerves to the line passing through medial and lateral epicondyles, as well as the length were mea?sured with regard to the motor nerve branches arising from median nerve to pronator teres, flexor carpiradialis, palm longus and flexor digiti superficialis, as well as the most proximal two motor branches to flexor carpi ulnaris arising from ulnar nerve. From September 2013 to August 2014, 4 male patients with ulnar coronoid fracture were treated operatively through the above anterior cubital approach in our hospital. They were all left side involved, with an average age of 32 years (range, 16-42 years). According to O’Driscoll classification, there were two cases of type Ib and two cases IIb respectively. They were all treated by open reduction and internal fixation through flexor?pronator teres interval. Results At cubital fossa, there were 2-3 branches to the pronator teres mostly, 1 branch to flexor carpiradialis and palm longus arising from median nerve. The branch to the flexor digiti superficia?lis usually was long and thick, and divided into 2-5 short twigs near muscle. The branch to palm longus had the same trunk with that to flexor digiti superficialis. The branch to flexor digiti superficialis was the most proximal among those passed through the in?terval of pronator teres and flexor carpiradialis, and its entry point to the muscle had an averaged distance of 37.22 mm to the line passing through medial and lateral humeral epicondyles. It was optimal to expose coronoid tip through the interval of pronator teres and flexor carpiradialis. It was safe to expose coronoid proximal to the branch to flexor digiti superficialis. While, it was better to expose the anteromedial facet and base of corocoid through the interval of palm longus and flexor carpiulnaris via median and ul?nar nerve interface. All of the four patients were followed up for an average period of 9 months. They all achieved bone union from 6 weeks to 3months (mean, 9 weeks). All the patients obtained excellent result according to the modified An&Morrey elbow per?formance index with scores from 94 to 100. Conclusion The novel anteromedial cubital approach via flexor?pronator teres is opti?mal for exposure of coronoid.

OBJECTIVETo explore the new mechanism of propranolol for treatment of hemangioma and the effects of propranolol on proliferation of hemangioma-derived mesenchymal stem cells ( Hem- MSCs).

METHODSWe isolated Hem-MSCs from hemangioma in the proliferating phase by their selective adhesion to plastic culture dishes. Immunofluorescence staining was used to examine the expression of marker antigens in Hem-MSCs. Human umbilical vein endothelial cells(HUVECs) were used as control. Indiuction of multi-lineage differentiation including osteogenesis and adipogeneis was performed with appropriate medium to identify the multi-lineage differentiation potential. MTT cell counting was used to observe the effects of different concentrations of propranolol on proliferation of Hem-MSCs.

RESULTSHem- MSCs were fibroblast-like morphology. All of them expressed vimentin, most expressed α-SMA,CD133, some expressed Glutl, and none of them expressed VEGF. Osteogenic, adipogenic differentiations of Hem- MSCs were induced successfully. Effects of low concentration of propranolol on proliferation of Hem-MSCs were not obvious, while high concentration of propranolol can inhibit the proliferation of Hem-MSCs.

CONCLUSIONSThe cells we isolated from hemangioma are Hem-MSCs. High concentration of propranolol can inhibit the proliferation of Hem-MSCs.
