Objective: To explore the family rehabilitation model for children with scar contracture after hand burns and observe its efficacy. Methods: A retrospective non-randomized controlled study was conducted. From March 2020 to March 2021, 30 children with scar contracture after deep partial-thickness to full-thickness burns of hands, who met the inclusion criteria, were hospitalized in the Burn Center of PLA of the First Affiliated Hospital of Air Force Medical University. According to the rehabilitation model adopted, 18 children (23 affected hands) were included in a group mainly treated by family rehabilitation (hereinafter referred to as family rehabilitation group), and 12 children (15 affected hands) were included in another group mainly treated by hospital rehabilitation (hereinafter referred to as hospital rehabilitation group). In the former group, there were 11 males and 7 females, aged (4.8±2.1) years, who began rehabilitation treatment (3.1±0.8) d after wound healing; in the latter group, there were 7 males and 5 females, aged (4.6±2.1) years, who began rehabilitation treatment (2.8±0.7) d after wound healing. The children in hospital rehabilitation group mainly received active and passive rehabilitation training in the hospital, supplemented by independent rehabilitation training after returning home; after 1-2 weeks of active and passive rehabilitation training in the hospital, the children in family rehabilitation group received active and passive rehabilitation training at home under the guidance of rehabilitation therapists through WeChat platform. Both groups of children were treated for 6 months. During the treatment, they wore pressure gloves and used hand flexion training belts and finger splitting braces. Before treatment and after 6 months of treatment, the modified Vancouver scar scale, the total active movement of the hand method, and Carroll quantitative test of upper extremity function were used to score/rate the scar of the affected hand (with the difference of scar score between before treatment and after treatment being calculated), the joint range of motion (with excellent and good ratio being calculated), and the function of the affected limb, respectively. Data were statistically analyzed with independent sample t test, equivalence test, Fisher's exact probability test, and Mann-Whitney U test. Results: The differences of scar scores of the affected hands of children in family rehabilitation group and hospital rehabilitation group between after 6 months of treatment and those before treatment were 3.0 (2.0, 7.0) and 3.0 (2.0, 8.0) respectively (with 95% confidence interval of 2.37-5.38 and 1.95-5.91). The 95% confidence interval of the difference between the differences of the two groups was -2.43-2.21, which was within the equivalent boundary value of -3-3 (P<0.05). The excellent and good ratios of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group were 3/23 and 2/15 respectively before treatment, and 15/23 and 12/15 respectively after 6 months of treatment. The ratings of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.58 and 2.30, respectively, P<0.05), but the ratings of joint range of motion of the affected hand between the two groups were similar before treatment and after 6 months of treatment (with Z values of 0.39 and 0.55, respectively, P>0.05). The functional ratings of the affected limbs of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.98 and 3.51, respectively, P<0.05), but the functional ratings of the affected limbs between the two groups were similar before treatment and after 6 months of treatment (with Z values of 1.27 and 0.38, respectively, P>0.05). Conclusions: The WeChat platform assisted rehabilitation treatment with mainly family rehabilitation, combined with hand flexion and extension brace can effectively reduce the scarring after children's hand burns, improve the joint range of motion of the affected hands, and promote the recovery of affected limb function. The effect is similar to that of hospital-based rehabilitation providing an optional rehabilitation, treatment method for children who cannot continue to receive treatment in hospital.

OBJECTIVE:
To analyze the clinical efficacy of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) by using parental donors on thalassemia patients.
METHODS:
The 13 thalassemia patients treated by haplo-HSCT using parental donors in our hospital from July 1, 2016, to July 1, 2020 were retrospectively reviewed. Hematopoiesis reconstitution, the incidence of GVHD, infections and the long-term survival of the patients were analyzed.
RESULTS:
Twelve of the 13 patients were successfully implanted, the success rate of implantation was 92.3%. The median time of neutrophil and platelet engraftment was 12.5 days (range, 9-22 days) and 21 days (range,12-34 days), respectively. One patient achieved primary graft failure. Three (25%) patients developed to acute GVHD (aGVHD) and achieved complete remission after treatment. Chronic GVHD developed in three (25%) patients, one of them was extensive and under treatment, while one patient developed to severe bacterial infection (7.7%). CMV viremia was diagnosed in two patients (15.4%). There were no patients developed to CMV disease. Three (23.1%) patients achieved EB viremia after transplantation, one of them developed to EBV-related lymphocytic proliferative disease, while there were no patients showed invasive fungal infection. At the last follow-up, all patients survived, twelve of them were free from transfusion dependency. There were no transplant-related deaths. Projected overall and thalassemia-free survival at three years was 100% and 92.3%, respectively.
CONCLUSION
The transplant protocol of haplo-HSCT by using parental donors in patients with thalassemia has reliable source of donors, high incidence of successful implantation and low incidence of GVHD, which can be used as an effective way to increase the source of donors in children with thalassemia.

Objective: Traditional Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy can greatly decrease the anastomosis-related complications and reduce the incidence of reflux esophagitis, but its complexity limits the wide application. To decrease the complexity of Kamikawa anastomosis, the surgical team of Changzhi People's Hospital of Shanxi Changzhi Medical College improved this technique by using novel notion and reduced surgical procedures. This study aims to evaluate the efficacy and safety of modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy. Methods: A descriptive cohort study was carried out. Case enrollment criteria: (1) upper gastric carcinoma or esophagogastric junction carcinoma without distant metastasis was confirmed by preoperative gastroscopic biopsy and imaging examination; (2) tumor diameter was less than 4 cm; (3) preoperative clinical staging was cT1-3N1M0. Exclusion criteria: (1) patients received preoperative neoadjuvant chemotherapy; (2) patients had severe heart or lung disease, or poor nutritional status so that they could not tolerate surgery. Clinical data of 25 patients with upper gastric carcinoma or esophagogastric junction carcinoma who underwent modified Kamikawa anastomosis in digestive tract reconstruction in Heji Hospital (8 cases) and Changzhi People's Hospital (17 cases) from April 2019 to December 2020 were retrospectively collected. Of 25 patients, 21 were male and 4 were female, with mean age of 63.0 (49 to 78) years; 3 underwent open surgery and 22 underwent laparoscopic surgery. The modified Kamikawa anastomosis was as follows: (1) the novel notion of total mesangial resection of the esophagogastric junction was applied to facilitate the thorough removal of lymph nodes and facilitate hand-sewn anastomosis and embedding; (2) the diameter of the anastomotic stoma was selected according to the diameter of the esophageal stump, between 2.5 and 3.5 cm, to reduce the occurrence of anastomotic stenosis; (3) an ultrasonic scalpel was used to incise the esophageal stump, which could not only prevent bleeding of the esophageal stump, but also closely seal the esophageal mucosa, muscle layer and serosa to prevent esophageal mucosa retraction; (4) barbed suture was used to suture the remnant stomach fundus and esophagus to fix the stomach fundus in order to reduce the cumbersome and difficult intermittent sutures in a small space; (5) two barbed sutures were used to continuously suture the front and back walls of the anastomosis and complete the suture and fixation of the muscle flap. Relevant indicators of surgical safety, postoperative complications (using the Clavien-Dindo classification), esophageal reflux symptoms and the occurrence of esophagitis (using Los Angeles classification) were analyzed. The gastroesophageal reflux disease (GERD) score, gastroscopy, multi-position digestive tract radiography during postoperative follow-up were used to evaluate the residual gastric motility and anti-reflux efficacy. Results: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy was successfully performed in 25 patients. The surgical time was (5.8±1.8) hours, the intraoperative blood loss was (89.2±11.8) ml, and the average hospital stay was (13.8±2.9) days. Three cases (12.0%) developed postoperative anastomotic stenosis as Clavien-Dindo grade III and were healed after endoscopic dilation treatment. Postoperative upper gastrointestinal radiography showed 1 case (4.0%) with reflux symptoms as Clavien-Dindo grade I. Gastroscopy showed no signs of reflux esophagitis, and its Los Angeles classification was A grade. No anastomotic bleeding, local infection and death were found in all the patients. At postoperative 6-month of follow-up, GERD score showed no significant difference compared to pre-operation (2.7±0.6 vs. 2.4±1.0, t=-1.495, P=0.148). Conclusion: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy is safe and feasible with good anti-reflux efficacy.

Itching is an unpleasant sensation that can cause physical and psychological discomfort. It often occurs in a variety of diseases. In addition to the common chemical medicines, the application of traditional Chinese medicines(TCMs) have attracted much attention for itch. As one of the classic antipruritic formula, Xiaofengsan is widely used by the later generations of doctors based on the edition of Orthodox Manual of External Diseases(Wài Kē Zhèng Zōng). It can be used to remove wind, dehumidify, clear heat and nourish blood by taking into account the complicated pathogenesis of skin diseases. In modern clinics, Xiaofengsan is commonly used for the treatment of rubella, eczema, acute and chronic urticaria, contact dermatitis, allergic dermatitis, psoriasis and other types of dermatitis with remarkable antipruritic effect. Its mechanism is related to its anti-allergic reaction, anti-allergy, anti-inflammatory, anti-histamine,immune regulation etc. This article reviews the research literature of Xiaofengsan and its addition and subtraction in modern pharmacological experimental research and clinical treatment in the past 15 years, and analyzes the current research situation of Xiaofengsan in the topic of antipruritic effect. The focus is on the compatibility characteristics of formula and the component study of single herb after being decomposed of Xiaofengsan, and the main material basis of antipruritic effect is summarized. It was found that Schizonepetae Herba, Saposhnikoviae Radix, Arctii Fructus, Cicadae Periostracum and Sophorae Flavescentis Radix were the main medicines for its antipruritic effect,which was helpful to expand the clinical value of Xiaofengsan and deepen its mechanisms of anti-itching.

BACKGROUND:
Positive surgical margins are independent risk factor for biochemical recurrence, local recurrence, and distant metastasis after radical prostatectomy. However, limited predictive tools are available. This study aimed to develop and validate a preoperative nomogram for predicting positive surgical margins after laparoscopic radical prostatectomy (LRP).
METHODS:
From January 2010 to March 2016, a total of 418 patients who underwent LRP without receiving neoadjuvant therapy at Peking University Third Hospital were retrospectively involved in this study. Clinical and pathological results of each patient were collected for further analysis. Univariable and multivariable logistic regression (backward stepwise method) were used for the nomogram development. The concordance index (CI), calibration curve analysis and decision curve analysis were used to evaluate the performance of our model.
RESULTS:
Of 418 patients involved in this study, 142 patients (34.0%) had a positive surgical margin on final pathology. Based on the backward selection, four variables were included in the final multivariable regression model, including the percentage of positive cores in preoperative biopsy, clinical stage, free prostate specific antigen (fPSA)/total PSA (tPSA), and age. A nomogram was developed using these four variables. The concordance index (C-index) of the nomogram was 0.722 in the development cohort and 0.700 in the bootstrap validations. The bias-corrected calibration plot showed a limited departure from the ideal line with a mean absolute error of 2.0%. In decision curve analyses, the nomogram showed net benefits in the range from 0.2 to 0.7.
CONCLUSION
A nomogram to predict positive surgical margins after LRP was developed and validated, which could help urologists plan surgical procedures.

Objective To investigate the relationship between single nucleotide polymorphisms of tumor suppressor gene PTEN and nasopharyngeal carcinoma in Jiamusi Han population. Methods The blood samples of 132 patients with naso-pharyngeal carcinoma(nasopharyngeal carcinoma group)and 73 healthy people(control group)were selected from September 2008 to January 2018 in the First Affiliated Hospital of Jiamusi University. The whole genome DNA was extracted,and the pol-ymorphisms of rs532678 and rs701848 were detected by restriction fragment length polymorphism analysis. The relationship be-tween the polymorphism of PTEN gene and nasopharyngeal carcinoma was analyzed. Results The genotype and allele frequen-cy distributions of rs532678 and rs701848 loci were in line with the Hardy-Weinberg genetic balance law in the two groups (P > 0. 05). The genotypic frequency of CC,CT and TT at the rs532678 locus of PTEN gene in the control group was 0. 630, 0. 342 and 0. 027 respectively;and the allele frequency of C and T was 0. 801 and 0. 198 respectively. The genotypic frequency of CC,CT and TT at the rs532678 locus of PTEN gene in the nasopharyngeal carcinoma group was 0. 716,0. 265 and 0. 015 re-spectively;and the allele frequency of C and T was 0. 852 and 0. 147 respectively. There was no significant difference in geno-type distribution and allele frequency distribution at the rs532678 locus of PTEN gene between the two groups(P > 0. 05). The genotypic frequency of CC,CT and TT at the rs701848 locus of the PTEN gene in the control group was 0. 657,0. 342 and 0. 000 respectively;and the allele frequency of C and T was 0. 828 and 0. 171 respectively. The genotypic frequency of CC,CT and TT at the rs701848 locus of PTEN gene in the nasopharyngeal carcinoma group was 0. 424,0. 500 and 0. 075 respectively;and the allele frequency of C and T was 0. 674 and 0. 325 respectively. The frequencies of CT,TT genotype and T allele of rs701848 locus in the nasopharyngeal carcinoma group were significantly higher than those in the control group(P < 0. 05). The frequencies of CC genotype and C allele in the nasopharyngeal carcinoma group were significantly lower than those in the control group(P < 0. 05). The individual with CT + TT genotype at the rs701848 locus of PTEN gene had higher risk for naso-pharyngeal carcinoma(P < 0. 05,OR = 2. 606,95% confidence interval:1. 439 - 4. 720). The risk for nasopharyngeal carcino-ma in the individual with CT + TT genotype was 2. 606 times as much as the individual carrying CC genotype. Conclusion The rs532678 polymorphism of PTEN gene is not associated with the susceptibility to nasopharyngeal carcinoma. The polymor-phism of rs701848 locus is associated with the susceptibility to nasopharyngeal carcinoma. The individual carrying CT + TT genotype has higher risk for nasopharyngeal carcinoma.

BACKGROUNDThe molecular genetic research showed the association between X-linked hearing loss and mutations in POU3F4. This research aimed to identify a POU3F4 mutation in a nonsyndromic X-linked recessive hearing loss family.
METHODSA series of clinical evaluations including medical history, otologic examinations, family history, audiologic testing, and a high-resolution computed tomography scan were performed for each patient. Bidirectional sequencing was carried out for all polymerase chain reaction products of the samples. Moreover, 834 controls with normal hearing were also tested.
RESULTSThe pedigree showed X-linkage recessive inheritance pattern, and pathogenic mutation (c.499C>T) was identified in the proband and his family member, which led to a premature termination prior to the entire POU domains. This mutation co-segregated with hearing loss in this family. No mutation of POU3F4 gene was found in 834 controls.
CONCLUSIONSA nonsense mutation is identified in a family displaying the pedigree consistent with X-linked recessive pattern in POU3F4 gene. In addition, we may provide molecular diagnosis and genetic counseling for this family.
