In Qin Han periods,the long-storaging method for Chinese materia medica(CMM) has been used in traditional Chinese medicine.People have named the Prescription with "chen" in the Song Dynasty,such as "Er Chen Tang".With the traditional Chinese medicine storing and treating with different methods in appropriate period,medicine becomes old medicine from the new,there by,reaching property of a medicine of reducing the poisonous or over-strong property,strengthening the medicine function and processing effect,getting rid of stench taste,increasing fragrant purpose,so as to further consistent with the demands of clinical treatment.By now,this traditional and distinct processing technique is on the verge of extinct.In order to fully reflect the superiority of long-storaged medicine by therapy,it is imminent to conserve,investigate and develop such medicine and such method.We should reinforce to research the changing of its effective component and pharmacology effect before and after processing drugs,discuss the contribution of the long-storaging method on the quality of CMM,so as to make this method applying and developing further.

Objective To study the changes of reactive astrocytosis after heat shock protein 70 (HSPT0) was blocked by anti-HSP70 antibody. Methods We established cell model of scratch inju-ries by in situ culture and prurification of rat astrocytcs. Anti-HSP70 antibody was added into the nutrient medium at once after injury for intervention (intervention group). Then, immunocytochemical staining of glial fibrillary acidic protein (GFAP) was done at different time points in control group and intervention group to observe astrocytosis and morphologic changes, mRNA expression of GFAP was observed by means of reverse transcriptase-polymerase chain reaction (RT-PCR). Results Compared with the con-trol group, average cell area, average dentritic length and number of dentrities of astrocytes were signifi-cantly reduced in the intervention group(P < 0.05 or P < 0.01), with down-regulated mRNA expression of GFAP (P < 0.05). Conclusion HSP70 plays a facilitative role in reactive astrocytosis after injury of astrocytes. Reactive astrocytosis can be controlled to some extent by blocking HSP70 with anti-HSP70 antibody.

Objective To study the diagnostic value of 3-dimensional CT reconstruction in posterior urethral strictures or ankylurethria.Methods Thirty patients with strictures or ankylurethria of posterior urethra caused by pelvic fracture underwent helical CT scan and 3-dimensional reconstruction of the urethral canal as well as radiographic urethrography before and post open urethral reconstruction to observe the urethral anatomy,the length and position of the urethral strictures,the depth of periurethral scar.Results The mean stricture or ankylurethria length measured by radiographic urethrography was 4.0 cm (range from 1.0 cm to 7.0 cm),and the correlation coefficient of stricture or ankylurethria length was 0.92,21 (70%) patients were diagnosed accurately by radiographic urethrography.The mean stricture or ankylurethria length measured by 3-dimensional CT reconstruction was 4.3 cm (range from 1.2 cm to 7.6 cm),and the correlation coefficient of stricture or ankylurethria length was 0.96,there were 28(93%) patients diagnosed accurately by 3-dimensional CT reconstruction.The mean stricture or ankylurethria length measured by open urethral reconstruction was 4.2 cm (range from 1.5 cm to 7.5 cm).Five patients with urethrorectal fistula were also diagnosed accurately by 3-dimensional CT reconstruction rather than by radiographic urethrography.Conclusions 3-dimensional CT reconstruction of the urethral canal can accurately evaluate the urethral anatomy,the length and position of the urethral strictures,as well as the depth of periurethral scar after crush injury and provide useful information for operation that may not be provided by radiographic urethrography.3-dimensional CT reconstruction may become the most valuable means for detecting posterior urethra strictures or ankylurethria with urethrorectal fistula.

ObjectiveTo evaluate the efficacy of using oral mucosal grafts (buccal mucosa and lingual mucosa) for urethroplasty in the treatment of anterior urethral strictures. Methods Between Jan 2001 and Dec 2010,255 patients with urethral strictures (length ranging from 3 cm to 18 cm,mean 6 cm)underwent one-stage onlay oral mucosal grafts urethroplasty.Two different techniques were used for urethral reconstruction.The first technique involved tubularized dorsal lingual mucosa graft (LMG) augmentation of urethral plate ; the second technique used dorsal patch graft urethroplasty.Of the 255 patients,49 patients with long-segment urethral strictures ( ≥ 8 cm) underwent dual buccal mucosal graft ( BMG),dual LMG,combined LMG and BMG or long-strip LMG urethroplasty. ResultsThe patients were followed up for 8 -120 months postoperatively ( mean 37 months).Of the 255 cases,230 cases voided well and the urinary peak flows ranged from 16 to 51 ml/s (mean 26 ml/s).The overall success rate was 90.2％.Seventeen cases developed a recurrence of urethral stricture.Among these patients,15 underwent BMG urethroplasty again and 2 underwent direct vision internal urethrotomy,after which the patients voided well.Eight cases presented with urethrocutaneous fistula,these patients underwent a second operation,after which,the urethrocutaneous fistulas were cured. Conclusions The buccal mucosa and lingual mucosa are excellent sources of graft materials for the repair of anterior urethral strictures.Combined two oral mucosal grafts substitution urethroplasty is an effective technique for the treatment of long-segment urethral strictures.

Orthodontic treatments have increasingly become accepted by adults. However, the treatment therapies and philosophies for adults and adolescents have numerous differences. Orthodontic treatment for adults requires more careful planning, flexible management, interdisciplinary cooperation, and rational expectations. New techniques, such as mini-screw implants, invisalign, and self-ligating brackets, have recently been used to update treatments and widen the application of adult orthodontics by improving the treatment results. However, orthodontists still face a number of risks and challenges.

Objective:To investigate the effect of modified York-Mason technique on urethrorectal fistula after radical prostatectomy.Methods:A retrospective analysis of clinical data from 20 patients with urethrorectal fistula after radical prostatectomy admitted to Shanghai Sixth People's Hospital from May 2016 to October 2022 was conducted. Patients’ average age was (76.6±4.2) years. The etiology was rectal injury during radical prostatectomy. Patients present urine leakage from the anus during micturition. 2 cases also had bladder neck stenosis, and 1 case had urinary incontinence.3 cases had radiotherapy history because of prostate cancer. The average duration of urethrorectal fistula was (1.8±2.3)years. Preoperative imaging confirmed the presence of contrast agent flowing from the bladder neck into the rectum. Three suspicious patients also underwent CT three-dimensional reconstruction. Urethroscopy revealed a depression at the bladder neck in five cases. Anorectal examination in five cases showed the formation of gas bubbles in the lower anterior wall of the rectum, along with a concave anterior wall. The distance from the fistula to the anal margin was (6.0±2.1) cm, with fistula diameters ≥1 cm in twelve cases, <1 cm in eight cases. Twelve patients had previously undergone cystotomy, and seventeen patients had undergone colostomy. The modified York-Mason procedure was adopted for all 20 cases. The patients were under general anesthesia and placed in the prone jackknife position, with the buttocks spread and fixed to the sides to expose the anus. An 8 cm-long incision was made from two points near the sacrococcygeal joint to the anal edge, representing the modified York-Mason approach. After dividing the anal sphincter muscle, both sides were marked using 3-0 chromium thread for subsequent anal reconstruction. The urethrorectal fistula was exposed, and the urethral side of the fistula was sutured with 4-0 absorbable thread, while the anterior rectal wall side was sutured with 3-0 absorbable thread. In cases of bladder neck stenosis, urethral internal incision was performed, and a urethral catheter was retained for 3 weeks postoperatively. Perianal incision drainage tubes were removed after three days. Patients had colostomy repair could eat the day after surgery, while those who didn’t were fast for five days and received intravenous nutrition.Results:All 20 cases in this group were successfully completed without complications during surgery. Follow-up ranged from 10 to 48 months after surgery. Seventeen (17/20)cases had unobstructed urination, with a maximum urine flow rate >15 ml, and no urine leakage from the anus. Postoperative urethrography and cystourethroscopy showed there were no urethrorectal fistulas in 15 cases. None of the patients experienced fecal incontinence after the surgery, except for three patients with a history of radiotherapy who continued to experience anal leakage. One patient underwent a second modified York-Mason procedure and achieved complete recovery three months after the second surgery. Another patient had anal discharge, and the fistula healed after two weeks of urethral catheter retention. One patient refused further treatment due to advanced age and frailty but still had anal leakage. Another patient experienced regular urethral dilation for urination difficulties, while one patient continued to have urinary incontinence.Conclusions:The modified York-Mason technique could be an effective method for urethrorectal fistula after radical prostatectomy with high success rate and few side effects.

There are few reports on laparoscopic repair of traumatic atresia of bladder neck. In this study, three patients with traumatic atresia of bladder neck were repaired by laparoscopic surgery, and the surgery was successfully completed. During postoperative follow-up, the patients had smooth urination, no urinary incontinence and sexual function damage, and laparoscopic surgery was effective in repairing traumatic atresia of bladder neck.

Objective:To investigate the effect of gracilis flap in repair of radiation-induced vesicovaginal fistula.Methods:The data of 18 patients with radiation-induced vesicovaginal fistula treated in the Sixth People’s Hospital Affiliated to Shanghai Jiaotong University School of Medicine from March 2021 to August 2022 were retrospectively reviewed. Their age was (57.3±10.4) years. All patients underwent radical surgery for cervical cancer, and received (24.6±2.8)(range from 20 to 30)times of radiotherapy after surger. The median time between the end of radiotherapy and the onset of vesicovaginal fistula was 14.0(7.8, 18.2)months. The median duration of fistula urine was 12.0(9.8, 18.0)months. All patients were required to use median 19.5(15.8, 27.5) pads per day before surgery. The life quality score(QOL)of 18 cases was median 5.0(5.0, 6.0) points. Three cases had performed laparoscopic vesicovaginal fistula repair, two cases had underwent transvaginal vesicovaginal fistula repair, one case had underwent transvaginal and laparoscopic vesicovaginal fistula repair successively, and the remaining 12 cases were new vesicovaginal fistulas. Two cases were combined with rectovaginal fistulas. All patients underwent the repair of vesicovaginal fistula with gracilis flap interposition in prone and folded knife position, by transvaginal route, the vesicovaginal fistula was mobilized and the two layers were closed, and the vascular pedicle gracilis flap of left inner leg was romoved under the skin tunnel to repair the vesicovaginal fistula. Meanwhile, two cases combined rectovaginal fistulas were repaired and closed the rectovaginal fistulas. The urinary catheters were removed at 3 weeks after the operation and urination was recorded.Results:All patients underwent smooth surgery in (96.6±13.2) minutes. The median follow-up was 13.0(9.8, 20.2)(range from 6 to 24)months. The median number of urine pads used per day in 18 patients was 2.0(1.0, 11.8), and significantly reduced ( P<0.01).QOL score was median 1.0(0, 4.2) point and significantly reduced ( P<0.01).Successful outcome was achieved in 12 patients with no leakage of urine in the vagina. Two cases developed urinary incontinence and required conservative treatment, but the curative effect was poor. Two cases still had vaginal urine leakage performed vesicovaginal fistula repair again. One case was successfully repaired without significant urine leakage.The other case still had significant urine leakage and the QOL score was 3 points. She refused further treatment for self-satisfied. Two cases still had vesicovaginal fistula and rectovaginal fistula after the surgery, and refused further surgery. Conclusions:Repair with gracilis flap interposition is a surgical method with few complications and reliable surgical effect for patients with radiation-induced vesicovaginal fistula.

Cachexia is a common complication in patients with lung cancer. It aggravates the toxic and side effects of chemotherapy, hinders the treatment plan, weakens the responsiveness of chemotherapy, reduces the quality of life, increases complications and mortality, and seriously endangers the physical and mental health of patients with lung cancer. The causes and pathogenesis of tumor cachexia are extremely complex, which makes its treatment difficult and complex. Controlling cachexia in lung cancer patients requires many means such as anti-tumor therapy, inhibition of inflammatory response, nutritional support, physical exercise, and relief of symptoms to exert the synergistic effect of multimodal therapy against multiple mechanisms of tumor cachexia. To date, there has been a consensus within the discipline that no single therapy can control the development of cachexia. Some therapies have made some progress, but they need to be implemented in combination with multimodal therapy after fully assessing the individual characteristics of lung cancer patients. This article reviews the application of drug therapy and nutritional support in lung cancer patients, and looks forward to the research direction of cachexia control in lung cancer patients.
