OBJECTIVETo evaluate and compare the efficacy and safety of titanoreine cream with compound carraghenates suppository in the treatment of mixed hemorrhoids.

METHODSTwo hundred and fifty-two patients with mixed hemorrhoids were enrolled in this randomized,open, multicentral trial. Patients applied titanoreine cream (study group, n=133) or compound carraghenates suppository (control group, n=119). The symptomatic relief including pain,bleeding and edema was evaluated by scoring system at 30 minutes, 3 hours, 6 hours, 1 day, 2 days, 3 days, 4 days, 6 days after administration.

RESULTSSymptoms were significantly improved in both groups (87.3%, 94.8%, respectively) excepting symptom of pain relief, but there was no significant difference between two groups (P > 0.05). The pain scores were lower at every observing point in the study group than those in the control group (P< 0.05). The proportions of the patients with pain relief and all symptoms relief were both higher in the study group than that in the control group at 30 min, 3 h after drug used (both P< 0.01). No side effect was found during the triad.

CONCLUSIONTitanoreine cream has predominance of relieving pain and response time compared with compound carraghenates suppository, but other effects on mixed hemorrhoid are similar between the two groups.

OBJECTIVETo probe the efficacy and feasibility of the transradial approach for diagnostic coronary angiography with 5F universal catheter.

METHODSTransradial coronary angiography was performed in 3094 consecutive patients, 2396 men and 698 women, aged 30 - 81 years, mean age (56.1 +/- 9.8) years, from July 2000 to April 2004. Patients were divided into 5F improved Terumo catheter group (improved Terumo group, n = 985), 5F universal Terumo catheter group (Terumo group, n = 1024) and 5F universal Medtronic catheter group (Medtronic group, n = 1085). The procedure success rate, duration of operation and fluoroscopy between groups were compared.

RESULTSThe procedure success rate was 98.4% in improved Terumo group, 98.0% in Terumo group, and 96.0 % in Medtronic group, respectively. The success rate was higher in improved Terumo group than in Medtronic group (P < 0.05). The average duration of operation and fluoroscopy in improved Terumo group was (17.9 +/- 5.8) min and (4.8 +/- 1.8) min, in Terumo group was (18.2 +/- 5.5) min and (5.0 +/- 1.7) min, but (21.1 +/- 7.2) min and (5.2 +/- 1.9) min in Medtronic group. There were significant differences among group (P < 0.05).

CONCLUSIONS(1) Transradial coronary angiography with small diameter universal catheter is safe and easy to perform with a higher success rate and allow earlier patient ambulation, and should be strongly encouraged and recommended. (2) Option of angiographic catheter plays a key role in the safety, efficacy and quality of transradial coronary angiography. Seemingly, the improved Terumo group was excellent and shoud be popularized.

BACKGROUNDChronic obstructive pulmonary disease (COPD) has a variable natural history and not all individuals follow the same course. This study aimed to identify the prevalence and characteristics of asymptomatic COPD patients from a population-based survey in China.

METHODSA multistage cluster sampling strategy was used in a population from seven different provinces/cities. All residents (over 40 years old) were interviewed with a standardized questionnaire and spirometry. Post-bronchodilator forced expiratory volume in 1 second (FEV(1))/forced vital capacity (FVC) of less than 70% was defined as the diagnostic criterion of COPD. All COPD patients screened were divided into symptomatic group and asymptomatic group according to the presence or absence of chronic respiratory symptoms. Socio-demographic, personal and exposure variables were collected and analyzed.

RESULTSAmong the 1668 patients who were diagnosed with COPD from the 25 627 sampling subjects, 589 (35.3%) were asymptomatic. The age, sex, body mass index (BMI), rural and urban distributions, smoking habit and education levels were similar in the two groups. A total of 64.7% of the asymptomatic patients had no comorbidities. Cardiovascular diseases and lung cancer were more common among symptomatic COPD patients than asymptomatic group. Asymptomatic COPD group were less likely to present with poor ventilation in the kitchen, a family history of respiratory disease and recurrent childhood cough. Asymptomatic COPD patients had significantly higher FEV(1) (73.1% vs. 61.0%), FVC (91.9% vs. 82.0%), and a higher ratio of FEV(1)/FVC (62.9% vs. 58.7%) (all P < 0.001) than symptomatic group. More asymptomatic patients were underdiagnosed (91.9% vs. 54.3%, P < 0.001) than symptomatic patients.

CONCLUSIONSThis large population-based survey confirmed a high prevalence of asymptomatic COPD patients in China. More use of spirometry screening test may be important to the early detection of COPD.

Objective To study a local hospital reported acute gastroenteritis in a boarding school on its source of infection, mode of transmission and risk factors of the infection. Methods A suspected case was defined as who had developed diarrhea (≥3 times/day) or vomiting among teachers or students of the school, during April 19-30, 2010. A confirmed case was from a probable case plus tested positive for norovirus in stool specimens by using RT-PCR. Stool specimens of cases and environmental specimens were collected for laboratory diagnosis. In a ease-control study, we compared exposures to sources of bottled water, consumption of bottled water, and hygienic habits of 220 probable or confirmed cases from April 21-23 in the peak of the outbreak, together with another 220 controls, with frequency-matched by school grade. Results 20.3% of the 1536 students but none of the teachers developed the disease. 98.6% of the cases (n=217) and 85.5% (n=188) of the controls had drunk bottled water in the classroom (ORM-H= 12.3,95%CI: 3.7-40.9). 47.9% (n= 104)of the cases and 41.5% (n=78)of the controls had drunk unboiled bottled water in classroom (ORM-H=3.8,95%CI: 1.5-9.6). 47.9% (n=104) of the cases and 48.4% (n=91) of the controls had drunk bottled mixed water (boiled and unboiled) in the classroom (ORM-H=2.8, 95%CI: 1.1-7.0).Stool specimens from 3 cases and one bottle of uncovered bottled water in classroom showed positive of having norovirus genotype Ⅱ. Coliforms was cultured much higher rates than standard deviations in the bottled water. The factory making the bottled water was not licensed or having strict disinfection facilities. Conclusion Bottled spring water contaminated by norovirus was responsible for this outbreak.

Objective To explore the imaging and clinical characteristics and related risk factors of patients with coronary artery stenosis located proximally to myocardial bridging.Methods This study enrolled 603 patients with angiography evidenced myocardial bridging-mural coronary artery between May 2004 to May 2009.Angiographic and clinic data were collected according to uniform protocol and standard questionnaires were used to obtain patients' demographic and clinical information.Univariate and multivariate analysis were performed to explore related risk factors.Results Chest pain was present in 247cases (41.0％).Dynamic ST-T changes were found in 229 cases (38％).A total of 644 myocardial bridging-mural coronary arteries were detected including 382 (62.4％) segments located proximally to myocardial bridging.Diastolic vessel diameters in the myocardial bridging segment were significantly smaller than reference segments (all P ＜ 0.01).Stepwise multiple regression analysis suggested that vascular bifurcation lesions,the degree of narrowing and the number of diseased coronary vessels of non-myocardial bridging-mural coronary arteries,age,LDL-C/HDL-C,male gender,diabetes,and systolic narrow rate of myocardial bridging-mural coronary arteries were positively related with the narrowing degree of the first coronary artery stenosis located proximally to myocardial bridging (P ＜ 0.05 or P ＜ 0.01).Vascular bifurcation lesions,the degree of narrowing and the number of diseased coronary vessels of non-myocardial bridging-mural coronary arteries,age,LDL-C/HDL-C,male,diabetes and dyslipidemia were positively related with the narrowing degree of the most severe coronary artery stenosis located proximally to myocardial bridging(P ＜ 0.05 or P ＜ 0.01).Conclusions Myocardial ischemia is common in patients with myocardial bridging and the artery segments located proximally to myocardial bridging are prone to stenosis.Systolic narrow rate of myocardial bridging-mural coronary arterics is one of major determinants of coronary artery stenosis located proximally to myocardial bridging.Whereas the other coronary heart disease risk factors are likely to play more important roles.

OBJECTIVE: The effects of the staurosporine on contraction of self-assembled constructs and extracellular matrix syntheses of goat temporomandibular joint discs were investigated. METHODS: Goat temporomandibular joint disc cells were isolated and cultured to P3, and 5.5×10⁶ cells were combined with different concentrations of staurosporine (0, 0.1, 1, 10, 100 nmol·L⁻¹) in agarose wells and cultured for one week. The samples were frozen and sectioned. Safranin-O,  Picro-sirius red and immunohistochemical staining were performed to observe the distributions of the extracellular matrix and the expression of alpha-smooth muscle actin (α-SMA). Enzyme linked immunosorbent assay (ELISA) and Blyscan kits were utilized to quan--titatively detect the contents of type Ⅰ collagen (ColⅠ) and glycosaminoglycans (GAGs). RESULTS: Each group of goat temporo-mandibular joint disc cells in the agarose wells were gathered to self-assemble into a disc-shaped base for 4 hours and then to gradually contract into a round shape. The Picro-sirius red staining was strong and indicated collagen distribution. The Safranin-O staining observed GAGs throughout the entire construct. The expression of ColⅠ was strongly posi-tive in the staurosporine groups; however, the expression of α-SMA was weak. ColⅠ and GAGs contents in the stau-rosporine groups were greater than that of the control group, especially in the 10 nmol·L⁻¹ group (P<0.01). CONCLUSIONS Staurosporine has a certain effect on the shrinkage of self-assembled constructs; however, such effect is not prominent. Staurosporine contributes to the construction synthesis of extracellular matrix.

“Cold-dampness entering ying （营）” is the key to the worsening of cold-dampness epidemic， and is more common in the elderly or critically ill cases of cold-dampness epidemic with pathogen exuberance and healthy qi deficiency. This paper reported a case of critically ill COVID-19 combined with multiple organ dysfunction treated by integrative traditional Chinese and western medicine based on “cold-dampness entering ying” theory. The patient did not have high fever after being infected with SARS-Cov-2， but D-dimer continued to increase， and she developed multiple thrombosis throughout the body and multiple organ dysfunctions such as pulmonary embolism， edema， oliguria， and shock. The patient were with enlarged and dusky tongue， with yellow， thick and greasy coating， and sublingual blood stasis， and thready， rapid and rough pulse. All these were characteristic manifestations of “cold-dampness entering ying”， and was differentiated as cold-dampness stasis. For the treatment， symptomatic and supportive western medicine of improving heart function， anti-infection， relieving asthma， stopping cough and reducing phlegm was given as the basic therapy， and additionally， traditional Chinese medicine to open the constraint and the blocked， save from collapse and restore yang， boost qi and relieve collapse， invigorate blood and drain water was used， usually with Modified Poge Zilong Xuanbai Chengqi Decoction （破格子龙宣白承气汤加减）， which was in accordance with the pathogenesis and thus achieving good effect.

ObjectiveTo investigate the diagnosis and management of penile fracture.

METHODSFrom June 1993 to May 2017, 46 cases of penile fracture were treated in our hospital, averaging 33.5 (25－42) years of age and 3.45 (1－10) hours in duration, of which 41 occurred during sexual intercourse, 4 during masturbation and 1 during prone sleeping, 4 with hematuria, but none with dysuria or urethral bleeding. Hematoma was confined to the penis. Emergency surgical repair was performed for all the patients, 45 under spinal anesthesia and 1 under local anesthesia, 16 by coronal proximal circular incision and the other 30 by local longitudinal incision according to the rupture location on ultrasonogram. The tunica albuginea ruptures averaged 1.31 (0.5－2.5) cm in length, which were sutured in the "8" pattern for 6 cases and with the 3－0 absorbable thread for 18 cases. The skin graft or negative pressure drainage tube was routinely placed, catheters indwelt, and gauze used for early pressure dressing. In the recent few years, elastic bandages were employed for 3－5 days of pressure dressing and antibiotics administered to prevent infection. The stitches and catheter were removed at 7 days after surgery.

RESULTSShort-term postoperative foreskin edema occurred in 14 of the 16 cases of circular degloving incision, but no postoperative complications were observed in any of the cases of local incision. Twenty-eight of the patients completed a long-term follow-up of 49.4 (10－125) months, which revealed good erectile function, painless erection, and satisfactory sexual intercourse.

CONCLUSIONSFor most penile fractures, local longitudinal incision is sufficient for successful repair of the tunica albuginea, with mild injury, no influence on the blood supply or lymph reflux, and a low rate complications. It therefore is obviously advantageous over circular degloving incision except when the cavernous body of urethra is to be explored, which necessitates circular degloving incision below the coronal groove.

OBJECTIVE: To verify the effect of Buyang Huanwu Decoction (BHD) in ameliorating erectile dysfunction (ED) after radical prostatectomy (RP). METHODS: The composition of BHD was verified by ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS) analysis. Bilateral cavernous nerve crush injury (BCNI) in rats was used to mimic the neurovascular injury occurring after RP. By the envelope method, forty rats were randomly divided into 4 groups as follows: sham (cavernous nerves exposed only), model (BCNI), low-dosage BHD [LBHD, 12.8 g/(kg·d)], and high-dosage BHD [HBHD, 51.2 g/(kg·d)] groups, 10 rats in each group, feeding for 3 weeks respectively. Erectile function was evaluated by measuring intracavernosal pressure (ICP). Changes in the histopathology of corpus cavernosum (CC) were examined by hematoxylin-eosin staining. Meanwhile, the fibrosis of CC was measured by Masson's trichrome staining and Western blot was used to detect the expressions of collagen I, transforming growth factor beta 1 (TGF- β 1) and α-smooth muscle actin (α-SMA). Apoptosis index was detected by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) and Western blot for determining the expressions of B-cell lymphoma 2 (Bcl-2) and Bcl-2-associated X (Bax). The oxidative stress in the CC were assessed by the superoxide dismutase (SOD), malondialdehyde (MDA) and reactive oxygen species (ROS) levels. The proteins expression of c-Jun N-terminal kinase (JNK) and c-Jun were detected by Western blot. In addition, the expression of α-SMA and p-c-Jun in the CC was observed by double immunofluorescence staining. RESULTS: The UPLC-QTOF-MS/MS analysis showed that BHD contained calycosin-7-O- β -D-glucoside, ononin, calycosin and formononetin. Compared with the model group, LBHD and HBHD treatment improved the ICP and the circumference, area, and weight of CC (P<0.05 or P<0.01). Furthermore, LBHD and HBHD treatments increased CC smooth muscle content and decreased apoptosis index (P<0.05 or P<0.01). LBHD and HBHD also elevated SOD and expression level of α -SMA and Bcl-2, and reduced MDA and ROS levels, as well as expression of TGF- β 1, collagen I, Bax, p-c-JNK, p-JNK in the CC compared with the model group (P<0.05 or P<0.01). The double immunofluorescence staining showed that the fluorescence degree of p-c-Jun in both LBHD and HBHD treatment groups was significantly reduced, whereas the α -SMA expression increased (P<0.05 or P<0.01). CONCLUSIONS BHD can improve ED of rats with BCNI, which is related to inhibiting fibrosis, apoptosis, and oxidative stress of CC. The ROS/JNK/c-Jun signaling pathway may play an important role in the process.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
