Henoch-Schonlein purpura(HSP) is one of the most common blood capillary allergic disorder in children, and its pathogenesis has not been well explained. The studies show that the main mechanism of HSP is the abnormality of humoral immunity, and the role of IgA is emphaszed. Meanwhile, many agents such as changes in T cell function,participation of cytokine and mediators of intlammation, suscepti-bility gene and other factors also play an important role in the incidence of HSP. The pathogenesis of HSP can be better understood through extensive analysis of the immunology factors,genetic factors,and so on.

Objective:To analyze the effect of Doula delivery combined with labor analgesia on the delivery process and delivery outcomes of primiparas.Methods:Retrospectively selected 200 primiparas treated in Beijing Friendship Hospital, Capital Medical University from January 1, 2019 to September 30, 2019 as the research objects.All patients underwent labor analgesia, and were divided into 100 cases in the Doula group and 100 cases in the control group (without Doula delivery) according to whether or not Doula delivery was performed.T test of two independent samples and chi square test were used to compare the labor process and delivery outcome of the two groups.Results:The natural delivery rate in the Doula group was 76%(76/100), which was significantly higher than the control group (61%(61/100)), and the difference was statistically significant (χ 2=5.214, P=0.022). The time of the first, second and third stage of labor in Doula group was (8.35±3.59), (1.07±0.26), (0.54±0.19) h, and that in the control group was (10.94±4.76), (1.86±0.63), (0.78±0.21) h, respectively.There were significant differences between the two groups (t value were 10.354, 5.312 and 8.169, respectively; P value were 0.016, 0.042 and 0.039, respectively). The neonatal asphyxia rates of Doula group and control group were 1% (1/100) and 3% (3/100) respectively, and there was no significant difference between the two groups ( P=0.621). The incidence of postpartum hemorrhage in the Doula group and the control group was 3% (3/100) and 10% (10/100) respectively, and the incidence of postpartum urinary retention was 0 (0/100) and 6% (6/100), respectively.The success rate of early sucking was 98% (98/100) and 90% (90/100) respectively, and the difference between the two groups was statistically significant (P value were 0.045, 0.029 and 0.017, respectively). The hospitalization time of Doula group was (3.17±0.85) d, which was significantly shorter than that of the control group (5.64±1.29) d)( t=6.359, P=0.031). The visual analogue pain score of 2 h postpartum in Doula group was 3.49±0.98, which was significantly lower than the control group (5.82±1.06)( t=9.327, P<0.001). Conclusion:Doula delivery combined with labor analgesia can effectively reduce the pain of uterine contraction, promote natural delivery, reduce the rate of cesarean section, help to improve the quality of obstetric medical service, improve patient satisfaction, it is worth promoting in the condition of the hospital.

Objective To investigate the effects of DNaseⅠ-treated streptococcal antigens on peripheral blood mononuclear cells(PBMC)proliferation in psoriasis patients.Methods PBMC from 15 patients with psoriasis and 10 healthy controls were stimulated with three concentrations(2,10,25?g/mL) of streptococcal antigens(SA), nd DNaseⅠ-treated streptococcal antigens(DNaseⅠ-SA).After 72 h of culture,cellular proliferation was determined by ~3H thymidine incorporation.Results The DNaseⅠ-SA,at all the concentrations tested,was less potent than the corresponding concentrations of SA(P0.05),however,the lower concentrations(2,10?g/mL) of DNaseⅠ-SA were less potent than those of SA(P0.05).Also,the extent of proliferation response to SA and DNaseⅠ-SA was higher in the patients than in the controls(P

Objective: To evaluate the effectiveness of Scarf osteotomy combined with Akin osteotomy in the treatment of moderate to severe hallux valgus with absorbable screws or metal screws fixation by clinical and radiological data. Methods: Between March 2014 and May 2016, the Scarf osteotomy combined with Akin osteotomy was used to treat 62 patients (83 feet) with moderate to severe hallux valgus. Twenty-five patients (35 feet) were fixed by absorbable screws (group A) and 37 patients (48 feet) were fixed by metal screws (group B). The difference in gender, age, affected side, etiology, severity, disease duration, preoperative hallux valgus angle (HVA) and first-second intermetatarsal angle (1-2IMA) measured in weight-bearing anteroposterior X-ray film, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) scores and visual analogue scale (VAS) scores between 2 groups ( P>0.05). The complications and healing time of 2 groups were recorded and compared. At last follow-up, the AOFAS and VAS scores, and HVA, 1-2IMA measured by weight-bearing anteroposterior X-ray film were used to evaluate the effectiveness. Results: All incisions healed by first intention and no incision-related complication occurred in the two groups after operation. Both groups were followed up, the follow-up time in group A was 12-36 months (mean, 24.4 months) and in group B was 14-38 months (mean, 25.7 months). In group A, 1 foot was complicated with hallux varus, 2 feet had mild stiffness, 1 foot appeared metastatic metatarsal pain, and in group B was 2, 3, 2 feet, respectively. There was no recurrence of hallux valgus in both groups. The difference in the incidence of complications between the two groups after the first operation was not significant ( χ2=0.275, P=0.843). The removal rate of internal fixator in group B was 89.2% (33 cases) during the second operation, among which 3 cases had screw slip and 1 case had screw fracture. And 10.8% (4 cases) refused the second removal operation due to their age. Postoperative X-ray films showed that both groups had good healing at the osteotomy site, and there was no significant difference in healing time between the two groups ( t=1.633, P=0.285). At last follow-up, the AOFAS score, VAS score, HVA, and 1-2IMA were significantly improved in the two groups when compared with preoperative ones ( P<0.05); but no significant difference was found between the two groups ( P>0.05). Conclusion: The effectiveness of Scarf osteotomy combined with Akin osteotomy in the treatment of moderate to severe hallux valgus is significant, with few complications. Compared with being fixed by metal screws, being fixed by absorbable screws has the same effectiveness, but can avoid the risk of second operation to remove the internal fixator.

Objective To explore the methodology of choosing the volume and shape of the mammary implant.Methods The changes of the volume and shape were analyzed in 502 cases of breast augmentation,to find out how to select the volume and shape of the mammary implant.Results The thoracic width H was the most important factor of choosing width of the implant; the SN was the important factor of choosing the height of the anatomic implant; After setting the diameter and height of the implant,a bigger breast could be achieved by increasing the projection of implants.For those very thin females with flat chest, anatomic implants were the better choice. Conclusions Thoracic width,breast volume and other data are the most important factors in choosing the mammary implant.Round and anatomic mammary implants have their specific indications.
