Objective To analyze the characteristics and malignancy of red-patch like lesion(RPL)during cystoscopy,and to explore the significance of RPL biopsy.Methods Clinical data of patients who had RPL detected in our hospital during Jan.2019 and Jun.2023 were retrospectively analyzed,including gender,age,cause of examination,presence of scars,complications and biopsy pathology.The patients were divided into the benign and malignant groups,and their clinical and RPL characteristics were analyzed.Results A total of 521 cases of RPL were enrolled including 416(79.8％)benign cases,and 105(20.2％)malignant cases.The averae age of the malignant group was higher than the benign group's[(66.8±12.2)years vs.(62.8±12.9)years,P=0.005].The malignant detection rate of RPL in postoperative follow-up patients,those with hematuria and those with lower urinary tract symptoms was 23.7％(92/389),19.6％(9/46),4.7％(4/86),respectively.According to direct observation and experience,the detection rate of pathological malignancy in the three groups of patients with high suspicion of RPL malignancy,mild suspicion of RPL malignancy and high probability of benign was 56.9％(37/65),37.0％(30/81)and 10.1％(38/375),respectively.Conclusion Once RPL is detected during cystoscopy,active biopsy should be performed.For elderly male patients undergoing postoperative follow-up,RPL biopsy is particularly important,especially when the lesion is located on or near the scar surface.

Objective To investigate the efficacy and safety of Chinese herbal compound modified Huanglian Wendan Decoction in the treatment of hypertension complicated with sleep disorders of phlegm-heat harassing the interior type.Methods A total of 70 patients with hypertension complicated with sleep disorders of phlegm-heat harassing the interior type were randomly divided into a control group and an observation group,35 cases in each group.The patients in the control group were treated with conventional western medicine,and the patients in the observation group were treated with modified Huanglian Wendan Decoction on the basis of treatment for the control group.The course of treatment covered four weeks.The Clinical Global Impression(CGI)score,traditional Chinese medicine(TCM)syndrome score,Pittsburgh Sleep Quality Index(PSQI)score,blood pressure,and serum levels of homocysteine(Hey),interleukin 6(IL-6),interleukin 10(IL-10)and interleukin 8(IL-8)levels in the two groups were observed before and after treatment.Moreover,the safety of medication was evaluated in the two groups.Results(1)After four weeks of treatment,the CGI score of the observation group was(1.63±0.60)points,which was significantly lower than that of the control group[(2.74±0.82)points],and the difference was statistically significant(P＜0.01).(2)After treatment,the TCM syndrome score,systolic blood pressure,diastolic blood pressure and PSQI score of the two groups were significantly decreased compared with those before treatment(P＜0.01),and the decrease of TCM syndrome score,systolic blood pressure,diastolic blood pressure and PSQI score in the observation group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(3)After treatment,the levels of serum Hcy,IL-6 and IL-8 in the two groups were significantly decreased compared with those before treatment(P＜0.01),and the serum IL-10 level was significantly increased compared with that before treatment(P＜0.01).The decrease of serum Hcy,IL-6 and IL-8 levels and the increase of serum IL-10 level in the observation group were significantly superior to those in the control group(P＜0.01).(4)During the treatment,no treatment-related adverse reactions or complications occurred in the two groups.Conclusion Modified Huanglian Wendan Decoction has certain efficacy on patients with hypertension complicated with sleep disorders of phlegm-heat harassing the interior type.The decoction can not only reduce the blood pressure and serum Hcy level of the patients,but also regulate the level of inflammatory factors with high safety.

Objective To investigate the nutritional status of children with cystic fibrosis(CF)and understand the correlation between malnutrition and clinical characteristics as well as lung function.Methods A retrospective analysis was performed on clinical data of CF children admitted from January 2016 to June 2023.Clinical characteristics of CF children with different nutritional statuses were compared,and the correlation between malnutrition and lung function was analyzed.Results A total of 52 CF children were included,comprising 25 boys(48％)and 27 girls(52％),aged between 7 months and 17 years.Respiratory symptoms were the predominant clinical manifestations(96％,50/52).The prevalence of malnutrition was 65％(34/52),with moderate/severe malnutrition being the most common(65％,22/34).The malnutrition group had a longer duration of illness,higher proportion of digestive system symptoms,and lower levels of serum albumin(P＜0.05).Pulmonary function parameters,including forced expiratory volume in one second as a percentage of the predicted value,ratio of forced expiratory volume in one second to forced vital capacity,forced expiratory flow at 25％of forced vital capacity exhaled,forced expiratory flow at 50％of forced vital capacity exhaled,forced expiratory flow at 75％of forced vital capacity exhaled,and maximum mid-expiratory flow as a percentage of the predicted value,were lower in the malnutrition group compared to the normal nutrition group(P＜0.05).Correlation analysis showed body mass index Z-score was positively correlated with the above six pulmonary function parameters(P＜0.05).Conclusions The prevalence of malnutrition is high in CF children and is associated with decreased lung function.CF children with higher body mass index have better lung function.Therefore,screening and evaluation of nutritional status as well as appropriate nutritional intervention should be emphasized in CF children.[Chinese Journal of Contemporary Pediatrics,2024,26(3):275-281]

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective The rabbit knee osteoarthritis(KOA)model was established by simple anterior cruciate ligament disruption.Methods The selected 40 adult white rabbits were randomly divided into two groups,blank group with 6 rabbits and model group with 34 rabbits.The rabbits in model group were given the disruption of anterior cruciate ligament of right knee joint.In the fourth,eighth and the twelfth weeks of modeling,different degrees of degenerative changes have been ob-served on the rabbits articular cartilages from both macroscopic and microscopic aspects.Results At 4,8 and 12 weeks after modeling,the articular cartilage of the rabbits in the model group showed degenerative changes in different degrees.At 8 and 12 weeks,the typical pathological manifestations of KOA in the middle and late stages were found in the infrapatellar fat pad and synovium,respectively.There were no changes in articular cartilage,infrapatellar fat pad and synovial membrane in the blank group at the same time.There were significant differences in the gross score between the model group and the blank group at 4 weeks[(1.300±0.674)vs 0.000],8 weeks[(2.400±0.516)vs 0.000]and 12 weeks[(3.583±0.668)vs 0.000](P＜0.05),the histopathological scores were significantly different,at 4 weeks[(2.900±0.567)vs 0.000],8 weeks[(7.500±1.178)vs(0.500±0.707)],12 weeks[(11.833±1.337)vs(1.500±0.707)],(P＜0.05).Conclusion The establishment of rabbit knee arthritis model by simply cutting the anterior cruciate ligament is simple and feasible,with good stability,high success rate,small trauma,short modeling cycle and less changes in animal physiological structure.The rabbit knee arthritis model es-tablished by simply cutting the anterior cruciate ligament has good modeling effect on different stages and grades of knee os-teoarthritis,and the postoperative infection and trauma can be controlled,which can meet the test requirements.

Purpose: Preoperative localization plays an important role in secondary hyperparathyroidism (SHPT) surgery. The advantages of neck ultrasound (US) include high availability and low cost. However, the reported sensitivity of US is 54%– 76%, and the reason for missed parathyroid glands (PGs) on US has been rarely addressed. Methods: Fifty-four patients who were diagnosed with renal SHPT from September 2020 to March 2022 were included in this retrospective study. Preoperative localization included surgeon-oriented US and technetium 99m-sestamibi singlephoton emission CT (SPECT)/CT. Results: A total of 212 PGs were pathologically confirmed, resulting in a success rate of 96.2% (52 of 54). Using echo, 193 PGs (91.0%) were accurately localized, while 19 glands (9.0%) were not identified, including those in ectopic positions (n = 12, at thymus or intrathyroid or others), of small size (<1 cm, n = 6), or overlapping with an ipsilateral PG (n = 1). US accurately detected 4 PGs in 36 (66.7%) patients, while SPECT/CT localized 4 glands in 19 patients (35.2%). Although the number of US-detectable PGs was not associated with success rate, it showed a significant negative correlation with surgical time (rs = –0.459, P = 0.002). Conclusion US detected 4 glands in 66% of SHPT patients with a sensitivity of 90% for localization. Ectopic position and small size were the most common reasons for the failure to detect PG on US. Complete preoperative echo localization might shorten operating time.

OBJECTIVE: To observe the clinical efficacy of lidong needling therapy (acupuncture technique combined with therapeutic movement of the body) on upper limb lymphedema after breast cancer surgery in combination with functional exercise. METHODS: A total of 73 patients with postoperative lymphedema of breast cancer in the upper limbs were randomized into an observation group (36 cases) and a control group (37 cases). The routine nursing care and functional exercise were given in the control group, twice a day, for about 10-15 min each time, lasting 8 weeks. On the basis of the treatment as the control group, lidong needling therapy was applied to the acupionts on the affected upper limb, i.e. Jianyu (LI 15), Waiguan (TE 5), Hegu (LI 4) and ashi points (the most obvious swelling sites), as well as to bilateral Yinlingquan (SP 9) and Zusanli (ST 36), etc. The needles were retained for 30 min. While the needles retained, the patients were asked to move the affected shoulder to 90° by the sagittal anteflexion and keep it elevated. Simultaneously, the hand on the affected side was clenched and opened slowly and coordinately. Lidong needling therapy was delivered once every two days, three times weekly for 8 weeks. Before and after treatment, the difference of the circumference between the affected and healthy limbs, the score of visual analogue scale (VAS) for swelling and the score of disability of arm, shoulder and hand (DASH) were compared in the patients of the two groups. The clinical efficacy was evaluated. RESULTS: After 2, 4, 6 and 8 weeks of treatment, except for the circumference of the area 10 cm below the cubitel crease in the control group, the differences in the circumferences of the rest parts between the affected and healthy limbs were reduced in comparison with those before treatment in the two groups (P<0.01, P<0.05). After 6 weeks of treatment, in the observation group, for the circumference at the level of hand between the thumb and the index finger and that of the wrist, the differences between the affected and healthy limbs was smaller compared with those in the control group (P<0.05). After 8 weeks of treatment, except for the areas 5 cm below and above the cubitel crease, the differences of circumferences between the affected and healthy limbs in the observation group were smaller than those in the control group in the rest parts (P<0.01, P<0.05). After 8 weeks of treatment, the swelling VAS scores were reduced when compared with those before treatment in the two groups (P<0.05), and the score in the observation group was lower than that in the control group (P<0.01). After 4 and 8 weeks of treatment, DASH scores were reduced in comparison with those before treatment in the two groups (P<0.01). The total effective rate of the observation group was 83.3% (30/36), which was higher than that of the control group (35.1%, 13/37, P<0.01). CONCLUSION Lidong needling therapy combined with the functional exercise obtains the satisfactory clinical effect on the upper limb lymphedema after breast cancer surgery. This treatment effectively relieves swelling and improves the upper limb function.

Objective:To explore indications for replantation of proximal proper digital artery and establishing extrinsic arterial perfusion pressure in the treatment of special type of severed digits with avulsion over 12.0 hours of warm ischemia, and to analyse the factors that affected the survival rate of the replanted digits.Methods:From September 2014 to January 2022, 8 patients with severed digits and prolonged warm ischemia were treated by transposition of adjacent digital artery together with the technique of extrinsic arterial perfusion pressure in the Department of Wrist and Hand Surgery, the Orthopaedic Hospital in Sichuan Province. During the operation, the defected proximal proper digital artery was reconstructed and repaired with vein graft, one side of the digital artery was repaired with an inverted "Y" vein graft, and one side of "Y" vein was bridged and anastomosed to repair the original digital artery. On the other side, the adjacent proximal proper digital arteries were transpositioned and anastomosed to gain an extrinsic arterial perfusion pressure, which increased the distal haemodynamic and reconstituted the blood supply. Of the 8 patients (9 severed digits) : 1 had severed index and middle fingers, 2 had severed index fingers, 4 had severed thumbs and 1 had severed little finger. All the patients were males, aged 16-63 years old, at 37.6 years old in average. Warm ischemia time of the severed digits were 12.3-20.6 hours, with 17.4 hours in average. The survival rate of replanted digits was observed after surgery. Postoperative follow-ups were conducted through telephone or WeChat reviews.Results:Follow-up time was 6-26 months, at 8.3 months in average. Retrospective analysis was performed. Vascular compromises occurred in 3 patients 4 digits (arterial insufficiency in 1 digit, venous congestion in 3 digits), skin necrosis occurred in 1 patient (1 digit) and digit necrosis in 1 patient (1 digit). Overall, 8 of the 9 replanted digits survived. According to the Replantation Function Evaluation Standard of Hand Surgery Association of Chinese Medical Association, the digit function after replantation was evaluated at excellent in 6 digits, good in 1 digit and poor in 1 digit.Conclusion:For a severed digit with an ischemia time over 12.0 hours, the survival rate can be improved by transposition of an adjacent digital artery to provided extrinsic arterial perfusion pressure.

The 2 patients were both aged females with medical history of diabetes mellitus. The chief complaints were both hyperpyrexia. Laboratory tests presented markedly elevated white blood cells and C-reactive protein, indicating severe systemic infections. Urine culture confirmed the growth of Escherichia coli. CT scan revealed thickened bladder wall with intraluminal and interstitial collections of gas. After the diagnosis of emphysema cystitis was established, conservative treatments including bladder drainage, strict glycemic control and sensitive antibiotics were administered timely. Both of the 2 patients got fully recovery after standard treatment.

Objective:To explore the practical application and clinical significance of modified grading system for Gastrointestinal Symptom Rating Scale (GSRS) scores in evaluating long-term postoperative gastrointestinal dysfunction (PGID) in patients after colon cancer surgery.Methods:A retrospective analysis was conducted on the case data of 122 patients who underwent right hemicolectomy for colorectal cancer at Beijing Friendship Hospital, Capital Medical University from September 2021 to September 2022. Among these patients, 69 were males (56.6%), and 53 were females (43.4%). The median age was 66.5 years, and the body mass index was (24.4±3.3) kg/m 2. The main observe indiator was GSRS scores of patients. The measurement data of normal distribution were represented as mean±standard deviation( ± s), and intergroup comparisons were conducted using ANOVA. The measurement data of non-normal distribution were expressed as the median (interquartile distance) [ M( Q1, Q3)], the Kruskal-Wallis H test was employed. Unordered count data comparisons were performed using the χ2 test, while comparisons for ordered count data between groups were conducted using the Kruskal-Wallis H test. GSRS scores were represented using density plots, and the scores were categorized into five symptom groups, presented using radar charts to illustrate the distribution of each symptom group. Results:Among the 122 patients, the most common long-term PGID syndromes was dyspepsia, followed by abdominal pain, diarrhea, and constipation. GSRS score data in the study population exhibited a nearly trimodal trend. Based on the overall data trend, the GSRS scale was refined, with cut-off values of 20 and 30, categorizing patients with right-sided colon cancer into low-risk, moderate-risk, and high-risk groups for quantifying the severity of long-term PGID. In terms of gender distribution, the differences among the three groups was statistically significant ( P=0.031), suggesting that males may be more susceptible to long-term PGID. However, there were no significant differences among the three groups concerning age, tumor location, surgical approach, anastomotic technique, lymph node dissection, pathological staging, adjuvant chemotherapy, and other factors. Conclusions:The modified grading system for GSRS scores aligns with the distribution characteristics of postoperative gastrointestinal function in colorectal cancer patients. It can quantify the risk of long-term PGID, allowing for a graded management approach to improve the postoperative quality of life for patients.
