[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

Objective:To explore the curative effects of foot microflap free transplantation in the repair of full-thickness electric burn wounds deep to tendon or even bone in fingers.Methods:A retrospective observational study was conducted. From July 2017 to February 2022, 20 patients with full-thickness electric burn wounds deep to tendon or even bone in fingers who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 19 males and 1 female, aged 18 to 64 years. Among the 20 wounds, 15 wounds were located on the palm side, including 8 on the thumb, 5 on the index finger, and 2 on the middle finger; 5 wounds were located on the back, including 1 on the index finger and 4 on the middle finger. After debridement, the wound area ranged from 4.5 cm×2.0 cm to 7.0 cm×3.0 cm. According to the principle of tissue structure similarity, 10 wounds were repaired with plantar medial flaps, 5 wounds were repaired with hallux peroneal flaps, and 5 wounds were repaired with dorsalis pedis artery flaps, with flap area of 5.0 cm×2.5 cm-8.0 cm×3.5 cm. The flaps were transplanted freely and arteries and veins and/or nerves were anastomosed at the same time. The wound in the donor site was repaired with thigh medium-thick skin graft. The survival of flaps and skin grafts were observed after surgery. The appearance of flap, temperature and color of the distal end in the affected finger were observed during follow-up. At the last follow-up, the joint function and flap sensory recovery of the affected finger were evaluated with the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association; the two-point discrimination distance of skin in the area of flaps with nerve anastomosis was measured; the satisfaction of patients with the curative effect was investigated by using the curative effect satisfaction rating scale, and the very satisfied rate was calculated; the repair effect of flap was evaluated by the comprehensive evaluation scale, and the excellent and good rate was calculated.Results:All the flaps and skin grafts survived after surgery. During the follow-up of 10-18 months after surgery, the appearance of flap was natural and not bloated; the temperature and color of the distal end in the affected finger were basically the same as that of normal finger skin. At the last follow-up, the function recovery of the affected finger joints was as follows: 11 affected fingers were within the normal range of motion, 6 affected fingers had their total active range of motion recovered to 85% of the healthy side, and 3 affected fingers had their total active range of motion recovered to 75% of the healthy side; the flap sensory recovery was as follows: the sense of 15 flaps with nerve anastomosis all recovered to grade S3 +, and the two-point discrimination distance of skin in the flap area was 7.0-9.0 mm; the sense of 1 flap without nerve anastomosis recovered to grade S2 and the sense of 4 flaps recovered to grade S1. The satisfaction with curative effect of 20 patients was very satisfied in 16 cases and moderately satisfied in 4 cases, with the very satisfied rate of 80%; the repair result of 20 flaps was excellent in 16 cases, good in 2 cases, and fair in 2 cases, with excellent and good rate of 90%. Conclusions:Due to the similar tissue structure of donor site and recipient site, foot microflap free transplantation in the repair of full-thickness electric burn wounds deep to tendon or even bone in fingers can achieve good appearance and function, with better functional and sensory recovery of the affected finger in the case of nerve anastomosis. Patients have high degree of satisfaction with the curative effects, which is worthy of promotion.

Objective:To analyze the influencing factors related to visiting rate of residents to contracted family doctors in a community health service center in Beijing.Methods:One thousand patients with contracted family doctor services who visited our center from January 2019 to December 2019 were selected for retrospective analysis. According to the corresponding visiting rate of contracted family doctors,patients were divided into low corresponding visiting rate, medium corresponding visiting rate and high corresponding visiting rate, and the influencing factors were analyzed.Results:Among the 1 000 patients, 481 (48.1%) were in the high corresponding visiting rate group, 342 (34.2%) in the middle corresponding visiting rate group, and 177 (17.7%) in the low corresponding visiting rate group. Univariate analysis showed that the corresponding visit rate was significantly associated with the age, marital status and educational level of patients, history of hypertension, the number of family doctor visits, the total visiting time and the consultation time per year (χ 2=12.55, 12.42, 7.69, 21.69, 253.97, 49.54, 9.07, all P<0.05). Multivariate logistic regression analysis showed that compared with the high corresponding visiting rate group, fewer of family doctor visits ( OR=0.68, 95 %CI: 0.58-0.78), lower education level( OR=0.65, 95 %CI: 0.46-0.92), history of hypertension ( OR=0.09, 95 %CI: 0.02-0.49), and 18-65 years old( OR=1.80, 95 %CI: 1.27-2.55) were the influencing factors for the low corresponding family doctor visiting rate(all P<0.05); while fewer of family doctor visits( OR=0.91, 95 %CI: 0.83-0.99),lower education level ( OR=0.74, 95 %CI: 0.55-0.98)and history of hypertension( OR=0.09, 95 %CI: 0.02-0.44)were the related factors of the medium corresponding visiting rate(all P<0.05). Conclusions:The visiting rate of patients to the contracted family doctor needs to be improved. The number of consultations of the contracted family doctor, educational background, history of hypertension, and age are the influencing factors of the corresponding visiting rate.

Objective:To analyze consecutive patients visits in a community health service station in Beijing.Methods:The basic information and behavior of the patients who visited Sanliheerqu Health Service Station in Beijing Xicheng district from January 1, 2015 to December 31, 2019 were retrieved from the electronic health records. The visiting situation, the stratification of the number of visits, and the correlation between the basic information and the consecutive visit was analyzed.Results:A total of 4 696 patients visited 202 560 times during 2015 to 2019, of whom 1 162 were consecutive patients (24.7%) with a total of 100 083 visits (49.4%).The annual number of visits, the total number of visits and the number of consecutive visits all showed an upward trend during the five years.The top 5 reasons for consecutive visit were all chronic diseases (hypertension, type 2 diabetes, dyslipidemia, coronary heart disease, and stroke) with median annual visits of 11 to 18, and it was increasing with the year. The rates of incidental visits (1-3/year, 66/1 162, 5.7%) and continuous visits (4-26/year, 1 020/1 162, 87.8%) in 2015 were higher than those in other years; while the rates of frequent visits (27-52/year, 71/1 162, 6.1%) and very frequent visits (>52/year, 5/1 162, 0.4%) were lower. The rates of frequent visits (181/1 162, 15.6%) and very frequent visits (78/1 162, 6.7%) in 2019 were higher than those in other years (χ 2=182.40, P<0.001).Compared with the non-consecutive visit group, the proportion of women (38.1%,735/1 930) and overweight/obesity (39.6%, 777/1 960) in the consecutive visit group was higher (χ 2=36.09, 69.69, P <0.001). Conclusion:The consecutive visit rate of residents in this institution needs to be improved. The utilization rate of primary medical resources for patients with consecutive visit is high and the number of medical visits is on the rise. Gender and BMI of patients may be related to consecutive visit.

Hierarchical diagnosis and treatment system is an important measure to rationally allocate medical resources and promote the homogenization of basic medical services. The medical alliance is an important service mode and service system of hierarchical diagnosis and treatment, whose role is to perfect the up-down linkage and meet the patient′s medical needs. Informatization construction is an important starting point to promote the services of the medical alliance. In order to solve the problem of connectivity, the medical alliance needs to establish a regional referral platform and realize the integrated service of all medical institutions. Renji Hospital, Shanghai Jiaotong University School of Medicine, has built a blockchain based referral system for hierarchical diagnosis and treatment, incorporating the S2B2C mode concept, and using the traceability, tamper proof and distributed accounting features of blockchain technology, realized independent storage of data in hospitals, realized real-time information sharing and interconnection, and provided a feasible solution for medical alliance management.

Objective:To investigate the coexistence status of common chronic diseases among hypertensive patients with contracted family doctor service in the community.Methods:Clinical data of 7 910 hypertensive patients with contracted family doctor service in Yuetan Community Health Service Center and its affiliated service stations were collected. The status of comorbidities and related factors were analyzed.Results:Among 7 910 hypertensive patients, there were 2 959 cases(37.4%) with 2 chronic diseases, 1 747 cases (22.1%) with 3 chronic diseases and 2 289 cases(28.9%) with simple hypertension. There was significant difference in comorbidity status among hypertensive patients in different age groups (χ 2=25.269, P<0.05). The top 3 comorbid chronic diseases were type 2 diabetes (2 979 cases, 37.7%), dyslipidemia (2 227 cases, 28.2%), and coronary heart disease (1 945 cases, 24.6%). Univariate analysis showed that the comorbidity of hypertensive patients was significantly related to age, smoking, marital status,employ status and education level (χ 2=9.697, 19.539, 33.343, 8.986, 7.923; P<0.05). Conclusion:There is a phenomenon of coexistence of multiple diseases in hypertensive patients with contracted family doctor service in Yuetan community.

Objective:To explore the efficacy and safety of transurethral anatomical vapor incision technique of prostate (VIT) with six-step method high power side-emitting greenlight laser in the treatment of benign prostatic hyperplasia (BPH).Methods:A retrospective analysis of 82 patients with BPH who used high power side-out green laser in the treatment from October 2018 to June 2020 in Gongli Hospital of Naval Medical University was performed. Among them, 40 patients were treated with six-step method VIT, and 42 patients were treated with photoselective vaporization of prostate (PVP). The two groups of patients were compared in age [(71.1±8.7)years vs.(72.1±7.0)years], prostate volume [75 (68.25, 89.00) ml vs. 73 (63.25, 85.00) ml], and peak urinary flow rate (Q max) [6.20 (5.20, 8.20) ) ml/s vs. 5.9 (4.75, 7.50) ml/s], post-void residual volume (PVR) [74.00 (42.50, 103.75) ml vs. 67.00 (58.00, 84.50) ml], international prostate symptom score (IPSS) [(21.2±5.2) vs. ( 21.0±3.9)], quality of life score (QOL) [5 (4, 6) vs. 5 (4, 6) ], prostate specific antigen (PSA) [6.20 (4.12, 8.43) ng/ml vs. 5.40 (3.88, 7.13) ng/ml ]. In general, there was no statistical difference ( P>0.05). The VIT group adopts the six-step method of marking, removing film, grooving, excision, trimming and crushing. In the PVP group, the prostate tissue was uniformly vaporized layer by layer from the inside to the outside. Perioperative indexes and complications were compared between the two groups. The Q max, IPSS, QOL, PVR and PSA between the two groups before and 3 months after surgery were compared. Results:All patients in the VIT group and PVP group successfully completed the surgery, and there was no case of transfer to TURP or open surgery. The average operation time was [60.00(50.00, 73.75)min vs. 70.00(50.00, 73.75)min] ( P<0.05). There was no significant difference in the amount of postoperative hemoglobin decline[15.00(10.00, 17.75)g/L vs. 16.00(14.00, 19.25)g/L], average bladder irrigation time[1(1, 1)d vs. 1(1, 1)d], indwelling catheterization time[3(3, 3)]d vs. 3(3, 3)d] and hospitalization time in patients after operation[4(3, 4)d vs. 4(4, 4)d] ( P>0.05). All patients had no blood transfusion, second bleeding, readmission, TURS, urethral stricture and urinary incontinence.There were 2 cases (5.0%) of postoperative urinary tract infection in the VIT group and 9 cases (21.4%) of postoperative urinary tract infection in the PVP group ( P<0.05), and they were cured after anti-inflammatory treatment. Three months after operation, Q max, IPSS, QOL, PVR and PSA in the two groups were significantly improved compared with preoperatively. Among them, the differences of IPSS [(5.7±2.5) points vs. (7.5±2.8) points] and PSA [2.65(2.10, 3.90)ng/ml vs. 4.00(2.45, 4.45)ng/ml] in the VIT group and PVP group after operation were statistically significant ( P<0.05). Conclusions:Applying the six-step method high power side-emitting greenlight laser transurethral anatomical VIT to treat BPH, there is less intraoperative and postoperative bleeding, short operation time, significant decrease in PSA, and fewer complications. It is a safe and effective minimally invasive technology for the treatment of BPH.

OBJECTIVE: To explore the correlation among gingival thickness (GT), underlying alveolar bone thickness (BT), and other periodontal biotype characteristics in the maxillary anterior. METHODS: A total of 40 young volunteers with healthy periodontal were involved in this research. The periodontal probe was previously used to divide the gingiva from thick to thin. Two records were measured by cone beam CT (CBCT) GT, which was measured at the cement-enamel junction level; and BT, which was measured at 3 locations: 1, 3, 5 mm below the alveolar crest. Oral and gypsum measurements were used to analyze the associations of the crown width/crown length ratio (CW/CL), the keratinized mucosa width (KM), and the free gingival margin curvature. RESULTS: Significant difference in the GT was observed between the thick and thin biotypes, which were divided by periodontal probe (P<0.01). Difference was observed in each periodontal biotype characteristic between the thick (GT≥1 mm) and thin biotypes (GT<1 mm) (P<0.05). BT was positively associated with GT (r=0.293, P=0.001), CW/CL (r=0.273, P=0.003), KM (r=0.291, P=0.001), and free gingival margin curvature (r=0.290, P=0.001). CONCLUSIONS The transparency of the probing in the sulcus could analyze the GT qualitatively. The thick and thin biotypes have different periodontal biotype characteristics. Compared with individuals with thick biotype, those with thin biotype are susceptible to risk dental aesthetic.

Objective:To explore the clinical effect of free anterolateral thigh flap combined with arterial vascular reconstruction on repairing high-voltage electrical burn wound of type Ⅱ and Ⅲ on the wrist.Methods:From May 2016 to February 2019, 25 patients with deep high-voltage electrical burn wounds on the wrist were admitted to Zhengzhou First People′s Hospital, including 23 males and 2 females, aged 11-63 years. Among them, 4 cases had bilateral electrical burns on the wrist, and 21 cases had unilateral electrical burns on the wrist. There were 29 wounds in 29 affected limbs with depth of full-thickness to full-thickness with tendon and bone exposure, and 17 wounds were type Ⅱ and 12 wounds were type Ⅲ. Twenty-four patients underwent CT angiography of the upper extremities before surgery, while the other one patient did not undergo the examination due to seafood allergy. There were no obvious injury to the ulnar and radial arteries in 7 affected limbs, simple ulnar artery injury in 6 affected limbs, simple radial artery injury in 7 affected limbs, and both ulnar and radial arteries injury in 9 affected limbs. The wound areas after debridement were 10 cm×7 cm-36 cm×17 cm, and the free anterolateral thigh flaps were obtained with area of 11 cm×8 cm-37 cm×18 cm for repairing the wounds. For patients with no damage of ulnar artery and radial artery, the trunk of descending branch of lateral circumflex femoral artery of the flap or combined with the thick muscle perforating branch or lateral branch was anastomosed with the ulnar or radial artery of the wound. For patients with simple ulnar artery or radial artery injury, the trunk, lateral branch, or medial branch was anastomosed with the ulnar artery or radial artery of the wound. For patients with long injury of ulnar artery and radial artery, the ulnar artery or radial artery of the wound was reconstructed with one of the above-mentioned methods, the injured artery that was not anastomosed was reconstructed with great saphenous vein, and the transplanted blood vessel was embedded in the lateral femoral muscle. The accompanying vein of the descending branch of the lateral circumflex femoral artery of the flap was anastomosed with the accompanying vein of the ulnar artery or radial artery of the wound and/or the cephalic vein. The donor sites of flaps were sutured directly or repaired with split-thickness skin graft from the thigh. The survival condition of flap and affected limb after operation and during follow-up was observed, and hand function of the affected limb during follow-up was evaluated according to the evaluation standard after repair of peripheral nerve injury in upper limbs.Results:Fifteen affected limb wounds had tissue liquefaction but healed after second debridement on 14-28 days after flap repair operation. All 29 flaps survived in the end. One patient had long ulnar artery and radial artery injuries in affected limbs and the hand was necrotic due to second embolism of the blood vessel in 1 week post operation, and the remaining affected limbs survived. During the follow-up of 6 to 30 months after operation, the flaps were slightly bloated, the affected limbs were warm with normal blood flow, and finger flexion, wrist flexion, and sensory function of hand recovered to varying degrees. The functions of the survived affected limbs were evaluated as excellent in 8 affected limbs, good in 9 affected limbs, medium in 5 affected limbs, and poor in 6 affected limbs, with an excellent and good rate of 60.71%.Conclusions:The clinical effect of free anterolateral thigh flap combined with arterial vascular reconstruction is good for repairing high-voltage electrical burn wound on the wrist, and the patency restoration of the ulnar artery and/or radial artery of the upper limb in stage Ⅰ is helpful for improving the success rate of limb salvage.

OBJECTIVE: Increased carotid artery intima-media thickness (CIMT) and carotid plaque as manifestations of carotid atherosclerosis have been used as markers of cardiovascular disease (CVD). The components of metabolic syndrome (MetS) are linked to CVD, but the association between MetS and CVD is controversial. METHODS: A total of 8,933 Chinese adults aged 40 years or older from 2010 to 2014 were selected from the Jidong and Kailuan communities. MetS was defined by the International Diabetes Federation criteria. CIMT and carotid plaque were measured using color Doppler ultrasound. Logistic regression models were used to assess the association of MetS with carotid plaque and CIMT. RESULTS: MetS was found among 3,461 (3,461/8,933) participants. The odds ratio and 95% confidence internal (CI) for carotid plaques in participants with MetS was 1.16 (1.03-1.30). The risk of carotid plaques increased with the number of MetS components. The average CIMT was higher in participants with MetS (β = 0.020, 95% CI, 0.014-0.027) and in participants with more MetS components. CONCLUSION Individuals with MetS are at an increased risk for carotid atherosclerosis compared to those without MetS.
