The aim of this study was to investigate the circulating levels of IL-11 in the patients with chronic idiopathic thrombocytopenic purpura (CITP), and its significance, and to evaluate the curative effect of rhIL-11 on CITP. The level of IL-11 in patients with CITP was determined by ELISA before and after treatment, respectively. 1.5 mg of rhIL-11 were injected subcutaneously, once a day, continuously for 14 days as one course, treatment time 1 - 2 courses as total. The results showed that the higher blood IL-11 level was found in CITP patients than that in controls (P < 0.01) and during the course of treatment the number of platelets in peripheral blood of patients with CITP parallelled to the level of IL-11. The platelet counts were obviously increased in all CITP patients after rhIL-11 treatment. It is concluded that the serum level of IL-11 in patients is correlated to the number of platelets in patients. rhIL-11 can be used as an effective treatment for CITP.

OBJECTIVETo evaluate the efficacy and safety of thrombopoietin (TPO) on platelet engraftment in hematological malignancies patients after allogeneic haematopoietic stem cell transplantation (allo-HSCT).

METHODSOne hundred and twenty patients were enrolled in a multicenter, open-label, randomized, controlled clinical trial, and were randomized into 4 treatment groups following allo-HSCT. Group A was the control arm without TPO, while group B, C and D were trial arms with received 300 U×kg(-1)×d(-1) of TPO starting from day +1, +4 and +7, respectively. A total of 89 cases were evaluated, of which 22 cases in group A, 23 in group B, 20 in group C and 24 in group D. Efficacy evaluation (the time of platelet engraftment, the number of platelet transfusion) and safety evaluation \[adverse events, routine blood tests, liver and renal function, coagulation function and occurrence of graft-versus-host disease (GVHD)\] were observed.

RESULTSThe median platelet engraftment time in experimental groups (groups B, C and D) were on day (13.17 ± 2.89), day (12.15 ± 2.08), day (12.33 ± 1.76), respectively, and that in control group was on day (14.82 ± 5.05). There was statistically significant difference between two groups (P = 0.029), There were no statistically significant difference in the average amount of platelet transfusion, platelet engraftment time, and platelet nadir value among the 3 experimental groups. No significant adverse events were observed in experimental groups.

CONCLUSIONSTPO administration following allo-HSCT for patients with hematologic malignancies appears to shorten platelet engraftment time. TPO given starting from day +7 is effective and safe.

OBJECTIVETo evaluate the short-term outcomes after hand-assisted laparoscopic radical gastrectomy.

METHODSBetween June 2010 and May 2011, a series of 15 patients underwent hand-assisted laparoscopic gastrectomy(HG), 16 patients underwent laparoscopic gastrectomy(LP), and 11 patients underwent open gastrectomy(OP). Short-term outcomes included operative time, blood loss, lymph nodes harvested, and the length of incision were collected after operation.

RESULTSThe operative time was 150-200 min in HG, 180-220 min in LP, and 150-200 min in OP respectively. The time of laparoscopic procedure was 18-58 and 70-100 min respectively. The average incision length was 6.8 cm in HG, 5.6 cm in LP, and 13.5 cm in OP. The average number of lymph nodes harvested was 17.6, 15.1 and 16.4 respectively. The average estimated blood loss was 228 ml, 278 ml, and 427 ml respectively. The mean length of hospital stay was 9.9, 10.8, and 12.4 d. No anastomotic leakage, bleeding, or gastric paralysis were found. One wound infection case was found in OP.

CONCLUSIONSHand-assisted laparoscopic gastrectomy is in concordance with the standardized treatment protocol for gastric cancer. Lymph node dissection is easier by HG, therefore HG can be an alternative for the radical resection of gastric cancer.

OBJECTIVETo explore the clinical characteristics of benign prostatic hyperplasia (BPH) complicated by chronic prostatitis (CP).

METHODSA total of 120 cases of BPH pathologically confirmed after transurethral resection of the prostate (TURP) were assigned to a BPH group (n=75) and a BPH + CP group (n=45) according to whether they were complicated by CP. The total prostatic volume (TPV) and PSA density (PSAD) were calculated and statistically analyzed based on the results of transrectal ultrasonography and f-PSA, t-PSA and f-PSA/t-PSA tests before surgery.

RESULTSThe BPH group showed a significantly upward tendency in f-PSA and t-PSA (P < 0.05) with the increase of age or prostate volume, but not significantly in PSAD and f-PSA/t-PSA (P > 0.05). In comparison, the BPH + CP group exhibited remarkable increases in f-PSA, t-PSA and PSAD (P < 0.05) but not in fPSA/t-PSA (P > 0.05). ROC curve analyses of various indexes showed the area under the curve to be 0.644, 0.628 and 0.624 for f-PSA, t-PSA and PSAD, respectively, all between 0.5 and 0.7.

CONCLUSIONBPH is frequently associated with CP. Clinically, high f-PSA, t-PSA and PSAD are important but not sure indicators of BPH complicated by CP.

OBJECTIVETo identify epidemic status of murine typhus in Hongta areas of Yuxi city and to provide evidence for control and prevention of the disease.

METHODSSerologic survey was conducted among residents and rodents. Isolation of Rickettsia moseri was performed.

RESULTSThe overall infection rate among general population was 28.92% (96/332) with geometric meantiter (GMT) as 10.83 and there was no difference between males and females (26.71%, 43/161 vs. 30.99%, 53/171, P > 0.05). Significant differences were found between age groups (P < 0.05) with positive rates of 29.63% (8/27), 18.06% (13/72), 39.62% (42/106), 27.50% (22/80) and 23.40% (11/47) among age groups 0-6, 7-18, 19-39, 40-59 and over 60, respectively. The overall rate of infection in mouse was 44.95% (89/198) with GMT as 30.30. Five isolates of R. moseri from mouse specimen, three from fleas plus one case of murine typhus were diagnosed. Rattus norvegicus and Rattus flavipectus were the predominant species of rodent animals (99.49%, 197/198) and Xenopsylla cheopis was the major species of vector (74.26%, 303/408). Flea index and mouse density were 2.06 and 11.13% respectively.

CONCLUSIONHigh infection rates on R. moseri were demonstrated in rodents and residents as well as high risk of murine typhus outbreak might occur in these areas.

Objective: To analyze the clinical characteristics and prognosis of 34 cases of acute myeloid leukemia (AML) with FLT3 internal tandem duplication (FLT3-ITD) and MLL gene rearrangement. Methods: The clinical data of 34 AML patients with FLT3-ITD and MLL gene rearrangement was compared and analyzed for the therapeutic efficacy, prognostic factors when treated with chemotherapy, chemotherapy combined with targeted therapy or allogenic hematopoietic stem cell transplantation (allo-HSCT). Results: Of the thirty-four cases with median age 41 (4-71) years old, 63.6% presented with white blood cells (WBC) greater than 30×10(9)/L, 39.4% greater than 50 × 10(9)/L respectively on admission. M(5) (35.3%) made up the highest proportion. The cytogenetic abnormality reached 61.8%, of which the complex cytogenetic abnormality accounted for 11.8%. Eleven patients (32.35%) had both FLT3-ITD and MLL gene abnormalities. In addition to FLT3 and MLL abnormalities, 23 patients (67.6%) had one or more other gene abnormalities (multiple gene abnormalities). Of the 34 cases, 29.4% patients went into complete remission (CR) after two courses of chemotherapy. 20.6% (7 patients) went into CR after 3 or more courses of chemotherapy. The rate of early relapse in the CR group was 52.9%. Patients with WBC>50×10(9)/L or multiple gene abnormalities had a lower remission rate (7.7%, 5.4%) after two courses of chemotherapy. CR rate for the patients with more than three gene abnormalities was 0. The total 2-year overall survival (OS) in the 34 patients was 28.8% (95% CI 13.5%-46.0%) and the disease-free survival (DFS) was 27.1% (95% CI 12.5%-44.0%). Of the 18 patients treated with chemotherapy alone or chemotherapy combined with targeted therapy, 17 cases died within 2 years and 1 lost follow-up after giving up treatment. For the 16 patients received allo-HSCT, the 3-year OS was 43.4% (95% CI 13.7%-70.4%) and DFS 42.7% (95% CI 13.4%-69.7%). Conclusion: AML patients with FLT3-ITD and MLL gene rearrangement often presented with M(5), accompanied by hyperleukocytosis, cytogenetic or multiple gene abnormalities. Those patients were observed to have low response rate and high early relapse when treated with chemotherapy without allo-HSCT. Patients had multiple gene abnormalities may be an important poor prognostic factor. Allo-HSCT is an effective treatment which could significantly improve the prognosis and survival of AML patients with FLT3-ITD and MLL gene abnormalities.

Objective To investigate the prevalence of tension-type headache(TTH)in children and adolescents aged 0-19 years globally in 1990-2021,and to provide a basis for the prevention and treatment of TTH.Methods Based on the Global Burden of Disease Study data,the age-standardized prevalence distribution of TTH and its changing trend were analyzed among the children and adolescents aged 0-19 years,with different sexes,age groups,sociodemographic index(SDI)regions and countries/territories.Results The age-standardized prevalence rate(ASPR)of TTH in children and adolescents aged 0-19 globally in 2021 was 17 339.89/100 000,which was increased by 1.73%since 1990.The ASPR in females was slightly higher than that in males(1990:17 707.65/100 000 vs 16 403.78/100 000;2021:17 946.29/100 000 vs 16 763.09/100 000).The ASPR in adolescence was significantly higher than that in school-aged and preschool periods(1990:27 672.04/100 000 vs 10 134.16/100 000;2021:28 239.04/100 000 vs 10 059.39/100 000).Regions with high SDI exhibited a higher ASPR than the other regions,with significant differences in prevalence rates across different countries.From 1990 to 2021,there was a slight increase in global ASPR,with an average annual percentage change(AAPC)of 0.06%.Females experienced a smaller increase than males based on AAPC(0.04%vs 0.07%).There was reduction in ASPR in preschool and school-aged groups,with an AAPC of-0.02%,while there was a significant increase in ASPR in adolescence,with an AAPC of 0.07%.ASPR decreased in regions with low-middle and low levels of SDI,with an AAPC of-0.02%and-0.04%,respectively,while it increased in regions with middle SDI,with an AAPC of 0.24%.Conclusions There is a consistent increase in the ASPR of TTH in children and adolescents aged 0-19 years globally,with significant differences across sexes,age groups,SDI regions and countries/territories.

BACKGROUNDThis study aimed to evaluate the effects of standard rescue procedure (SRP) in improving severe trauma treatments in China.

METHODSThis study was conducted in 12 hospitals located in geographically and industrially different cities in China. A standard procedure on severe trauma rescue was established as a general rule for staff training and patient treatment. A regional network (system) efficiently integrating prehospital rescue, emergency room treatments, and hospital specialist treatments was built under the rule for information sharing and improving severe trauma treatments. Treatment outcomes were compared between before and 1 year after the implementation of the SRP.

RESULTSThe outcomes of a total of 74,615 and 12,051 trauma cases were collected from 12 hospitals before and after the implementation of the SRP. Implementation of the SRP led to efficient cooperation and information sharing of different treatment services. The emergency response time, prehospital transit time, emergency rescue time, consultation call time, and mortality rate of patients were 24.24 ± 4.32 min, 45.69 ± 3.89 min, 6.38 ± 1.05 min, 17.53 ± 0.72 min, and 33.82% ± 3.87% (n = 441), respectively, before the implementation of the standardization and significantly reduced to 10.11 ± 3.21 min, 22.39 ± 4.32 min, 3.26 ± 0.89 min, 3.45 ± 0.45 min, and 20.49% ± 3.11%, separately (n = 495, P < 0.05) after that.

CONCLUSIONSStaff training and SRP can significantly improve the efficiency of severe trauma treatments in China.

Objective: To explore the effects of expanded frontal-parietal pedicled flap in reconstructing cervical scar contracture deformity in children after burns. Methods: A retrospective observational study was conducted. From January 2015 to December 2020, 18 male children with cervical scar contracture deformity after burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, aged 4 to 12 years, including 10 cases with degree Ⅱ cervical scar contracture deformity and 8 cases with degree Ⅲ scar contracture deformity, and were all reconstructed with expanded frontal-parietal pedicled flap. The surgery was performed in 3 stages. In the first stage, a cylindrical skin and soft tissue expander (hereinafter referred to as expander) with rated capacity of 300 to 500 mL was placed in the frontal-parietal region. The expansion time was 4 to 6 months with the total normal saline injection volume being 2.1 to 3.0 times of the rated capacity of expander. In the second stage, expander removal, scar excision, contracture release, and flap transfer were performed, with the flap areas of 18 cm×9 cm to 23 cm×13 cm and the secondary wound areas of 16 cm×8 cm to 21 cm×11 cm after scar excision and contracture release. After 3 to 4 weeks, in the third stage, the flap pedicle was cut off and restored. The rated volume of placed expander, total normal saline injection volume, type of vascular pedicle of flap, survival of flap and reconstruction of scar after the second stage surgery were recorded. The neck range of motion and cervico-mental angle were measured before surgery and one-year after surgery. The appearance of neck, occurrence of common complications in the donor and recipient sites of children, and satisfaction of children's families for treatment effects were followed up. Data were statistically analyzed with paired sample t test. Results: All the patients successfully completed the three stages of operation. The rated volume of implanted expander was 300 mL in 6 children, 400 mL in 9 children, and 500 mL in 3 children, with the volume of normal saline injection being 630 to 1 500 mL. The type of vascular pedicle of flap was double pedicle in 13 cases and was single pedicle in 5 cases. All the flaps in 17 children survived well, and the secondary wounds after neck scar excision and contracture release were all reconstructed in one procedure. In one case, the distal blood supply of the single pedicled flap was poor after the second stage surgery, with necrosis of about 2.5 cm in length. The distal necrotic tissue was removed on 10 days after the operation, and the wound was completely closed after the flap was repositioned. In the follow-up of 6 months to 3 years post operation, the cervical scar contracture deformity in 18 children was corrected without recurrence. The flap was not bloated, the texture was soft, and the appearances of chin and neck were good. The range of motion of cervical pre-buckling, extension, left flexion, and right flexion, and cervico-mental angle in one year after operation were improved compared with those before operation (with t values of 43.10, 22.64, 27.96, 20.59, and 88.42, respectively, P<0.01). The incision in the frontal donor site was located in the hairline, the scar was slight and concealed. No complication such as cranial depression was observed in expander placement site, and the children's families were satisfied with the result of reconstruction. Conclusions: Application of expanded frontal-parietal pedicled flap in reconstructing the cervical scar contracture deformity in children after burns can obviously improve the appearance and function of neck, with unlikely recurrence of postoperative scar contractures, thus it is an ideal method of reconstruction.
