ABSTRACT
Primary hyperoxaluria (PH) is a rare autosomal recessive hereditary disease, characterized by calcium oxalate kidney stone and nephrocalcinosis caused by defects in enzymes of liver glyoxylate metabolism. Up to now, treatment options for PH are limited. Although medication treatment and liver transplantation can slow down the progression and mitigate the symptoms, the evidence for them turned out to be weak. In recent years, breakthroughs in biotechnology provide novel promising directions for drug development. Small interfering RNA drugs, such as lumasiran and nedosiran, selectively reduce hepatic expression of glycolate oxidase and lactate dehydrogenase respectively, reducing hepatic oxalate production and urinary oxalate levels in PH patients. Gene-editing, such as CRISPR/Cas9, will be a potential treatment method of PH. This review encompasses recent developments in the gene therapy of PH.

ABSTRACT
Some kidney stones are caused by single gene mutations, and monogenic kidney stone diseases associated with purine metabolic disorder mainly including adenine phosphoribosyltransferase(APRT) deficiency, hypoxanthine-guanine phosphoribosyltransferase(HPRT)deficiency, hereditary xanthinuria(HX), and some diseases caused by gene mutations such as PRS1, SLC22A12, SLC2A9 and ABCG2. Such diseases can lead to abnormal metabolism of purine and uric acid, and then form 2, 8-dihydroxyadenine stones, uric acid stones or xanthine stones. This kind of diseases are rare, the genotype and phenotype of different types of monogenic diseases related to purine metabolism have their own characteristics and are not widely recognized. At present, the main treatment is medical therapy. Gene sequencing will make the diagnosis and find more disease-related genes or mutations. Gene editing, such as CRISPR/Cas9 technology, makes it possible to cure monogenic kidney stone diseases associated with purine metabolism disorder in the future.
ABSTRACT
Objective:To analyze the factors influencing breast milk volume in mothers of preterm infants during the period of maternal separation.Methods:This study retrospectively analyzed the data from lactation diaries of mothers of preterm infants ( n=371) in neonatal intensive care unit from the first Affiliated Hospital of Zhengzhou University from January 2017 to August 2021. According to whether the milk production reached 800 ml/d or not within two weeks after delivery, these women were divided into the reached group ( n=289) or unreached group ( n=82). Two independent sample t-test and Chi-square test were used for univariate analysis, and logistic regression was used to analyze the influencing factors. Results:Mothers who achieved the target milk volume accounted for 77.9% (289/371). There were no statistically significant differences in the ratio of milk production ≥50 ml between breasts or between two adjacent breastfeeding sessions (both P>0.05), while there were statistically significant differences in the maternal education background[high school education or below:16.3% (47/289) vs 41.5% (34/82); junior college or above:83.7% (242/289) vs 58.5% (48/82); χ2=23.77], type of breast pump [diaphragm breast pump:34.9% (101/289) vs 51.2% (42/82); piston pump: 65.1% (188/289) vs 48.8% (40/82); χ2=7.14], pre-pregnancy body mass index [<18.5 kg/m 2: 3.5% (10/289) vs 4.9% (4/82);≥18.5～<24.0 kg/m 2: 90.7% (262/289) vs 61.0% (50/82); ≥24.0 kg/m 2: 5.9% (17/289) vs 34.1% (28/82); χ2=40.89], and the initiation of lactation instruction [within 7 d after delivery: 77.2% (223/289) vs 45.1% (37/82);at 7-14 d after delivery: 22.8%(66/289) vs 54.9%(45/82); χ2=31.28] between the reached and unreached group (all P<0.05). Logistic regression analysis showed that high school education or below ( OR=4.279, 95% CI: 2.253-8.126, P<0.001), diaphragm breast pump ( OR=2.352, 95% CI: 1.309-4.226, P=0.004), pre-pregnancy body mass index ≥24.0 kg/m 2 ( OR=9.352, 95% CI: 4.389-19.928, P<0.001), and seeking lactation consultation at 7-14 d after delivery ( OR=3.654, 95% CI: 2.043-6.535, P<0.001) were risk factors for not achieving the target milk volume. Conclusions:Instruction on breastfeeding for less-educated mothers of preterm infants should be strengthened. Using piston breast pump, maintaining pre-pregnancy body mass index within the normal range, and receiving lactation instruction as early as possible will contribute to achieving the target milk volume.
ABSTRACT
Objective:To evaluate the indications, surgical skills and clinic outcomes of abdominal minimal incision sacrocolpopexy (AMISC) for treatment of advanced pelvic organ prolapse (POP).Methods:The retrospective study analyzed 30 women with advanced POP who underwent AMISC between June 2016 and October 2019, including 9 cases of recurrent prolapse and 10 cases of vault prolapse. AMISC was especially applicable to: (1) patients with several medical complications who was unable to tolerate general anesthesia or laparoscopic surgery, but able to tolerate combined spinal-epidural anesthesia and open surgery; (2) other abdominal procedures were indicated to perform with AMISC simultaneously, such as myomectomy, subtotal hysterectomy etc, the specimens were easy to get out of the abdominal cavity and morcellation was avoided; (3) surgeons preferring open surgery to laparoscopic surgery or skilled in open surgery; (4) patients with prior pelvic operations, presenting severe abdominal and pelvic adhesions. Objective outcomes were assessed by pelvic organ prolapse quantification (POP-Q) system. Subjective outcome were assessed by pelvic floor distress inventory-short form 20 (PFDI-20), pelvic floor impact questionnaire-short form (PFIQ-7) and patient global impression of improvement (PGI-I).Results:All patients with 1-3 medical complications were successfully performed with AMISC without stopping procedure, enlarging the incision or changing to other procedure, the operation duration was (110±19) minutes. The mean time of follow-up was (33.5±12.4) months (range: 8-49 months). The postoperative points of Aa, Ba, C, Ap, Bp reduced significantly and point C improved from (2.33±2.50) cm to (-7.54±1.18) cm after AMISC ( P<0.01). The objective cure rates were both 100% (30/30) in apex and posterior compartment, while 97% (29/30) in anterior compartment. Postoperative scores of PFDI-20 and PFIQ-7 were all significant decreased (all P<0.01). About PGI-I, 29 patients chose “significant improvement”, subjective satisfaction was 97% (29/30). Anterior sacral plexus hemorrhage occurred in 2 cases (7%, 2/30). There was no intestinal obstruction or injury of bladder, bowel and ureter intra- and postoperation. Two cases (7%, 2/30) had mesh exposure. Conclusion:AMISC is a safety, convenient, minimal traumatic and durable procedure for apical prolapse with short learning curve in the most of cases.
ABSTRACT
Nephrocalcinosis is often accompanied by kidney stone disease. In recent years, more and more nephrocalcinosis has been found to be caused by a monogenic disease, and its pathogenesis has not been fully elucidated. With the development of molecular genetics, more than 30 genes have been found to be the causative genes of nephrocalcinosis. At the same time, with the widespread development of genetic testing technology, more patients have received early diagnosis and timely intervention. This article reviews the clinical and basic research progress of monogenic nephrocalcinosis.
ABSTRACT
Primary hyperoxaluria (PH) are important causes of kidney stone and chronic kidney stone disease in children. Recurrent kidney stone disease and nephrocalcinosis should alter the physician to the possibility of an inborn error of metabolism as the underlying cause. Unfortunately, the lack of recognition of genotype and phenotype of PH resulted in an unacceptable delay in diagnosis and treatment, sometimes with grave consequences. This paper review the characteristics of genotype and phenotype, genotype-phenotype correlation, current treatment and future gene therapy of PH.
ABSTRACT
Objective:To establish a predictive model that can predict the effectiveness and safety of endoscopic surgery for pediatric upper urinary tract calculi, and evaluate its diagnostic efficacy through internal validation.Methods:The data was selected from the prospective database of pediatric upper tract calculi constructed by Beijing Friendship Hospital Affiliated to Capital Medical University from June 2014 to April 2019. A total of 348 children were recruited in this investigation including 250 boys and 98 girls, with a median age of 3.0 years(Interquartile Range 1.4, 7.0 years). Totally 375 endoscopic surgeries were performed, with an overall stone free rate (SFR) of 88.0% (330/375) and complication rate (CR) of 23.2% (87/375). This research used univariate and multivariate logistic regression analysis to evaluate and screen the predictors of SFR and CR. The nomogram of SFR and CR was established by using the selected predictive factors. The differentiation degree of the model was evaluated by the area under the curve (AUC), the consistency between the prediction probability and the actual risk was evaluated by the calibration curve, and the clinical benefits of the model application were assessed by the decision curve.Results:The results of multivariate analysis demonstrated that stone burden, operation duration, intraoperative perfusion, stone location and operative options were the postoperative predictors of SFR and CR for children. Besides, BMI was also a predictor of postoperative CR. The AUC of the model (model 1: SFR; model 2: CR) based on the above predictive factors was 0.81 and 0.73, respectively. The predictive probability of the calibration curve showed that the model had a good consistency with the actual value. The decision curve showed that the application of model 1 to predict SFR had significant clinical benefits when the threshold value was greater than 20%, and the application of model 2 to predict the postoperative CR had a significant clinical benefit when the threshold was greater than 10%.Conclusions:Nomogram based on stone burden, operation time, intraoperative perfusion, stone location and operative options was validated internally with preferable predictive power on the effectiveness and safety of pediatric endoscopic surgery. This model can be used to predict the clinical effects of pediatric endoscopic lithotripsy. BMI was also an important factor for the safety of pediatric endoscopic procedures.
ABSTRACT
In recent years, multiple monogenic causes of nephrolithiasis have been identified.Monogenic nephrolithiasis can lead to renal calculus, nephrocalcinosis, extrarenal manifestations, renal insufficiency and renal failure.Advances in genetic testing techniques have improved the ability to obtain a definitive diagnosis of monogenic causes of kidney stone diseases efficiently and effectively.Similarly, advances in gene therapy technologies, especially gene editing, promise to change the way to treat patients with monogenic inherited nephrolithiasis.Now, the classification, cha-racteristics of genotype and phenotype, and the treatment of monogenic causes of nephrolithiasis were reviewed.
ABSTRACT
Objective:Assessing the prognosis of patients with bladder urothelial carcinoma by using multiple molecular markers [epithelial-cadherin (E-cadherin), fibroblast growth factor receptor 3 (FGFR3), Jagged2, Survivin and stromal antigen 2 (STAG2)] in combination method, and compared it with the traditional method of evaluating prognosis by clinical pathological parameters.Methods:Retrospective analysis of 128 cases of bladder urothelial carcinoma patients admitted to Beijing Friendship Hospital, Capital Medical University from January 2010 to December 2016, including 102 males and 26 females; the median age was 70.5 years, ranged from 41 to 93 years. E-cadherin, FGFR3, Jagged2, Survivin and STAG2 alterations by immunohistochemistry during the first surgical treatment. The Kaplan-Meier survival curve was used to evaluate the relationship between the above markers and overall survival (OS), recurrence-free survival (RFS), progression-free survival (PFS), and clinicopathological indicators of tumors. Use Cox regression model to find the most suitable molecular markers for judging the prognosis of bladder urothelial carcinoma, and compare it with the traditional clinical staging + pathological grading method to evaluate OS to detect its sensitivity and specificity.Results:After 36.4 months of follow-up, it was found that the expressions of E-cadherin, FGFR3, Jagged2 and Survivin were all related to the OS, RFS and PFS of bladder urothelial carcinoma (all P<0.05). The expression of STAG2 was related to the TMN stage of bladder urothelial carcinoma ( P=0.047) and pathological grade ( P=0.015). Cox regression analysis showed that Survivin ( P=0.001) and Jagged2 ( P=0.037) were independent risk factors for evaluating the OS of bladder urothelial carcinoma, and Survivin ( P<0.001) and Jagged2 ( P=0.006) were independent risk factors for RFS, Survivin ( P=0.001) was also an independent risk factor for PFS. Multivariate analysis of the above molecular markers showed that the prognosis of patients with more than 3 molecular markers was better than that of independent application or the use of two of them to evaluate the prognosis ( P<0.001). The combined application of Survivin and Jagged2 to evaluate the 5-year survival rate was not less sensitive and specific than the clinical and pathological indicators (93.5% vs 77.2%, 84.7% vs 81.3%). Conclusions:Five molecular markers of E-cadherin, FGFR3, Jagged2, Survivin and STAG2 have an evaluation effect on the prognosis of bladder urothelial carcinoma, and some can independently predict the OS and RFS of patients with bladder urothelial carcinoma, however, the combined application is better than the single molecular marker to evaluate the prognosis. Compared with the traditional method of evaluating the prognosis by clinical pathological parameters, the combined application of Jagged2 and Survivin may be a better choice for evaluating the prognosis of patients with bladder urothelial carcinoma.

ABSTRACT
Objective To assess the five?year effect of the transvaginal high uterosacral ligament suspension (HUS) with or without additional concomitant native?tissue anterior and (or) posterior repair in women suffering from middle compartment defect. Methods A retrospective review of records identified 79 women who underwent transvaginal HUS with or without additional concomitant native?tissue anterior and (or) posterior repair from January 2007 to January 2018 in Fourth Medical Center, General Hospital of People′s Liberation Army. The middle compartment defects were predominant in these patients with point C no less than point Ba or Bp if accompanied with anterior or posterior vaginal wall prolapse. Follow?up visits were performed 2,6 and 12 months after surgery and then annually. Anatomic results of pelvic organ prolapse (POP) was established by pelvic examination using pelvic organ prolapse quantitation system (POP?Q) staging. Funtional results were obtained by patient global impression of improvement (PGI?I) scale in POP, pelvic floor distress inventory?short form 20 (PFDI?20) and pelvic floor impact questionnaire short form (PFIQ?7). Surgical success required the fulfillment of all 3 criteria: (1) anterior or posterior vaginal wall prolapsed leading edge of 0 cm or less and apex of 1/2 total vaginal length or less; (2) the absence of POP symptoms as reported on the PFDI?20 question No.3 ("Do you usually have a bulge or something falling out that you can see or feel in your vaginal area?"); and (3) no prolapse reoperations or pessary use during the study period. Results Of 79 women, 51(65%, 51/79) women completed the five?year follow?up during the study period. The median follow?up time was 5.2 years (2.8-8.3 years). The overall surgery success rate was 86% (44/51) according to above all 3 criteria. Prolapse recurrence rates were isolated anterior 8% (4/51), isolated apical 0, isolated posterior 2% (1/51) and multiple compartments 4% (2/51). Seven women (14%,7/51) developed anterior or posterior prolapse beyond the hymen with the leading edge≤1 cm. No apical prolapsed occurred. None of recurrent women underwent retreatment,including either surgery or pessary usage at last follow?up. The subjective satisfaction rate was 90% (46/51). There was a 1% (1/79) rate of intraoperative ureteral kinking and 3% (2/79) rate of postoperative morbidity. Conclusions The transvaginal HUS for middle compartment defect offers good long?term anatomical results with excellent vault suspension. With additional concomitant native?tissue anterior and (or) posterior repair, it will be a reconstructive surgery for the majority of moderate?to?severe POP. It is minimal traumatic and worthy of being popularized for clinical application.
ABSTRACT
Objective To evaluate the indications and clinic outcomes of vaginal high uterosacral ligament suspension (HUS) for treatment of recurrent advanced pelvic organ prolapse (POP). Methods This retrospective study analyzed 42 women with recurrent advanced POP who were referred to Fourth Medical Center of PLA General Hospital and underwent transvaginal HUS between November 2005 and January 2018. Primary surgeries included 30 vaginal colporrhaphy, 5 Manchester operation, 5 transvaginal mesh repair,2 sacrospinous ligament fixation.The median time for recurrence from primary pelvic floor repair surgery was 9 months, including 14 cases (33%, 14/42)≤3 months (median time was 2 months) and 25 cases (67%, 28/42) longer than 3 months (median time was 18 months).The rate of recurrent prolapse in stageⅢorⅣ was 79% (33 cases), 45% (19 cases) and 17%(7 cases) in anterior, apical and posterior compartment respectively. Results Transvaginal high bilateral uterosacral ligaments were identified and used for successful vaginal vault suspension after vaginal hysterectomy and residual cervical resection in all 42 consecutive patients. The cases of transvaginal mesh used in anterior wall and posterior wall were 25 (60%, 25/42) and 3 (7%, 3/42) respectively. There was no major intra-and postoperative complications,such as ureter and other pelvic organ injury. The median time of follow-up was 5.3 years after transvaginal HUS. The points of pelvic organ prolapse quantification system reduced significantly and point C improved from+0.3 cm to-8.2 cm after reoperation (P<0.01). The objective cure rate were 100% (42/42) both in apex and posterior compartment,while 93% (39/42) in anterior compartment. None had reoperation or pessary usage for recurrence of prolapse. Conclusion Transvaginal HUS with vaginal wall repair could be as a safety, cost-effective, minimal traumatic and durable procedure for recurrent POP in the most of cases.

ABSTRACT
To observe corrected visual acuity and contrast sensitivity (CS) in patients with hypertensive disorders complicating pregnancy accompanied by fundus changes. Methods: Ninety-eight patients with hypertensive disorders complicating pregnancy and 50 healthy pregnant women underwent eye examination, including corrected visual acuity and fundus examination, and CS. Differences in corrected visual acuity and contrast sensitivity between the 2 groups were analyzed with two independent samples t-test analysis, while correlation between vision and contrast sensitivity in patients was evaluated by using spearman correlation test. Difference in CS was compared between the early and advanced stage of fundus diseases. Results: Corrected visual acuity and contrast sensitivity in patient with hypertensive disorders complicating pregnancy were lower than that in the control group (P<0.01). Corrected visual acuity in patients was associated with contrast sensitivity at variously spatial frequencies (P<0.01), showing the most correlation in contrast sensitivity at 6 of spatial frequency (r=0.87). Compared with the early stage, the CS in the advanced patients with fundus diseases was decreased (P<0.01). Conclusion: The visual acuity and contrast sensitivity in patient with hypertensive disorders complicating pregnancy are reduced. The CS (6.0 c/d) has the largest correlation with corrected visual acuity. Comparing with the visual acuity, contrast sensitivity can be more comprehensive in evaluation of retinal function damage in patients with hypertensive disorders complicating pregnancy.

Objective To understand the disinfectant resistance of clinically isolated Escherichia coli (E.coli)and carriage of disinfectant resistance genes.Methods Disinfectant resistance gene sugE (c ),sugE (p ),qacEΔ1 ,and qacE of 82 isolates of E.coli were detected with polymerase chain reaction (PCR),minimal inhibitory concentra-tions (MICs)were measured with agar dilution methods.Results Among 82 E.coli isolates,positive rates of dis-infectant resistance gene sugE (c ),sugE (p ),qacEΔ1 ,qacE,sugE (c )+qacEΔ1 ,and qacE+qacEΔ1 +sugE (c ) were 84.15% (n=69),1 .22% (n=1),76.83% (n=63),73.17 % (n=60),68.29% (n=56),and 59.76% (n=49)respectively.There was no significant differences in carriage status of four disinfectant resistance genes be-tween extended-spectrumβ-lactamases (ESBLs)-producing and non-ESBLs-producing strains,as well as cefepime sensitive and resistant strains (all P >0.05);MIC values of benzalkonium chloride,cetylpyridinium chloride,am-monium bromide,and triclosan for 82 isolates of E.coli were all > standard stain;MIC values of chlorhexidine for 32 isolates of E.coli were all > standard stain,for 50 other E.coli strains were all ≤ standard strain.There were no significant difference in MIC values of benzalkonium chloride,cetylpyridinium chloride,ammonium bromide,and triclosan between ESBLs-and non-ESBLs-producing strains,as well as cefepime sensitive and resistant strains(all P >0.05);while MIC values of chlorhexidine showed a significant difference (both P <0.05).Conclusion Detection rates of disinfectant resistance gene qacE,qacEΔ1 ,and sugE(c)in E.coli from clinical specimens are high,MICs of disinfectants such as benzalkonium chloride for E.coli are generally higher than standard strain.
ABSTRACT
Objective To observe the contrast sensitivity (CS) of patients with branch retinal vein occlusion (BRVO) without involving the macular region.Methods 92 BRVO patients (93 eyes) and 56 cases (112 eyes) without eye diseases (control group) were included in the study.According to different region,BRVO patients were divided into the nasal BRVO group (31 eyes) and temporal BRVO (62 eyes) group,and the average corrected visual acuity was 1.02 ± 0.13 and 0.98 ± 0.12 respectively.According to the type of ischemia,BRVO patients were divided into the nonischemic BRVO group (58 eyes) and ischemic BRVO group (35 eyes),the average corrected visual acuity was 1.01 ± 0.14 and 0.99 ± 0.12 respectively.The average corrected visual acuity of the control group was 1.03 ± 0.11.There was no statistically significant difference of the average corrected visual acuity between nasal BRVO group,temporal BRVO group and control group (F=3.03,P =0.06),and between nonischemic BRVO group,ischemic BRVO group and control group (F=1.60,P=0.20).Contrast sensitivity (CS) was measured by OPTEC 6500 vision tester (Stereo Company,USA) under the standard lighting conditions and different spatial frequencies including low (1.5 and 3.0 c/d),medium (6.0 c/d) and high frequencies (12.0 and 18.0 c/d).Results The CS under each spatial frequency of the nasal BRVO group was the same as the control group (t=4.25,9.48,3.08,5.86,0.94;P＞0.05),but the CS under each spatial frequency of the temporal BRVO group was different from the control group (t=8.59,19.11,10.38,17.28,6.01;P＜0.05).The CS under high spatial frequency of the temporal and nasal BRVO group was statistically different (t=11.42,6.95;P＜0.05).The CS under each spatial frequency of the ischemic BRVO group was different from the control group (t=8.88,10.56,11.64,19.06,6.67;P＜0.05).The CS under 6,12 and 18 c/d spatial frequency of the nonischemic BRVO group was statistically different with the control group (t =10.14,11.54,2.82;P＜0.05).The CS under 12 and 18 c/d spatial frequency of the nonischemic BRVO group was statistically different with the ischemic BRVO (t=7.52,3.84;P＜0.05).Conclusions The CS of the temporal BRVO and ischemic BRVO decreased more significantly under each spatial frequency.CS is a better indicator to evaluate the visual function than the visual acuity in BRVO without involving the macular region.
ABSTRACT
Objective:To evaluate the vital signs changes,influence factors in different grades of hy-pertension patients during the treatment of acute pulpitis,in order to obtain the risk prevention measures. Methods:In this study,90 different grades of hypertension patients with acute pulpitis were recruited from February 201 4 to February 201 5 in the Department of Oral Emergency,Peking University School and Hospital of Stomatology.The information about the patients’general health,oral treatment,life signs of change information was collected.Patients were divided into high risk group,middle risk group, and low risk group (30 patients for each group).Results:(1 )Compared with the preoperative,systolic blood pressure (90%),diastolic blood pressure (80%),heart rate increase (1 00%)were increased in the high risk group.The increase rates of the middle risk group and the low risk group were significantly lower than those of the high risk group (P<0.01 ).At the same time,the systolic blood pressure of 1 /4 (26.7%)patients in high risk group increased more than 20 mmHg (1 mmHg=0.1 33 kPa),and the diastolic blood pressure of 2/5 patients in high risk group increased more than 1 0 mmHg,the difference was statistically significant compared with the other two groups (P<0.05).(2)Compared with the pre-operative,the average increase of the maximum peak were increased [systolic blood pressure (1 8.0 ± 1 .5)mmHg,diastolic blood pressure (8.0 ±1 .7)mmHg],the mean of heart rate changes [(7.0 ± 0.3)beats per minute]was also increased in the high risk group,while these two indicators were de-creased in the low risk group and the middle risk group.The electrocardiogram (ECG)was changed in 6 cases during the treatment in the high risk group.No significantly changed were observed in the low risk group and the middle risk group.(3 ) Compared the risk assessment in preoperative with that in postoperative,in the middle risk group,23 cases were evaluated as medium risk in final evaluation,6 as low risk,and 1 as high risk (risk assessment increased);in the high risk group,20 cases were evaluated as high risk,7 as very high risk,and 3 as medium risk (risk assessment decreased).Conclusion:Oral treatment is very safe for patients with hypertension,but the risk factor,target organ damage,and com-plications will also increase the risk of cardiovascular events in elderly patients during the acute pulpitis treatment.Dentist should take some measures to avoid the risks.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the clinical efficacy difference between encircling needling combined with physical factor therapy and simple physical factor therapy for severe pressure sore, and to explore the optimal method for severe pressure sores.</p><p><b>METHODS</b>Thirty-four patients with IV-grade pressure sore were randomly divided into an observation group and a control group, 17 cases in each one. Patients in the control group were treated with conventional nursing, ultrasonic wave and short-wave ultraviolet therapy; additionally, the encircling needling was applied in the observation group. All the treatment was given once a day, 5 times a week, and 4-week treatment constituted one session. Totally, two sessions of treatment were performed. Three indices, including the area of pressure sore, 24-h volume of exudates and wound-bed tissue type, were compared between the two groups before and after treatment; the clinical efficacy was evaluated in the two groups.</p><p><b>RESULTS</b>After treatment of one session and two sessions, the area of pressure sore, 24-h volume of exudates and wound-bed tissue type were significantly reduced in the two groups (P < 0.01, P < 0.05), which was more obvious in the observation group (all P < 0.05). The total effective rate in the observation group was 76.5% (13/17) after 1 session and 94.1% (16/17) after 2 sessions, which were superior to 35.3% (6/17) after 1 session and 64.7% (11/17) after 2 sessions in the control group (both P < 0.05).</p><p><b>CONCLUSION</b>Encircling needling combined with physical factor therapy can obviously reduce the pressure sore area and 24-h volume of exudates and improve wound-bed tissue type, which is superior to simple physical factor therapy.</p>
