This paper summarized Professor PENG Peichu's experience in the differentiation and treatment of prostate cancer in three phases and four stages. It is considered that prostatic cancer is categorized into root deficiency and branch excess, with depletion of healthy qi as the root, and the accumulation of cancer toxin as the minifestation. Clinical diagnosis and treatment of prostatic cancer can be divided into three phases and four stages according to the exuberance and decline of pathogenic and healthy qi and the changes of deficiency and excess of yin and yang. In the initial accumulation phase of cancer toxin (yang excess stage), the key pathogenesis is the accumulation of dampness, heat and static blood, and internal generation of cancer toxin, and the treatment should be resolving toxins, fighting cancer and dispelling yang excess. In the phase of healthy qi deficiency and toxin accumulation (yin deficiency stage), with the lung and kidney yin deficiency, dampness, heat and static toxin accumulation as the key pathogenesis, the treatment should be centered on mutual generation between metal and water to nourish kidney yin, supplemented with the method of clearing heat and draining dampness, activating blood and resolving toxins, for which self-made Nanbei Formula(南北方)is usually used. In the phase of yang deficiency and cold stagnation (yang deficiency stage and yin excess stage), with the spleen and kidney yang deficiency, cold dampness stagnation, static heat and toxin accumulation as the key pathogenesis, the treatment should be warming and tonifying spleen and kidney to dissipate cold accumulation; for deficiency of both yin and yang, and excess pathogen obstruction, modified Yanghe Decoction(阳和汤) is recommended, while for yang deficiency, cold congealing and blood stasis, self-made Wenshen Sanjie Formula(温肾散结方) can be used, and for cold dampness binding with cancer toxin, and cold complex with heat, self-made Quanan Formula (泉安方) is advised.

Objective:To investigate the effect of pelvic floor muscle exercise (PFMT) combined with transcutaneous electrical nerve stimulation (TENS) on urinary incontinence after radical prostatectomy.Methods:A total of 120 patients with urinary incontinence after radical prostatectomy in Shuguang Hospital, Shanghai University of Traditional Chinese Medicine from July 2020 to June 2021 were retrospective selected and divided into control group and observation groupthe according to different treatment method, 60 cases in each group. The control group was treated with PFMT, and the observation group was treated with PFMT combined with TENS. Urodynamic indexes of 72 h urine pad usage, maximum urine flow rate, maximum cystometric capacity, maximum urethral closure pressure, abdominal leakage point pressure, ICI-Q-SF score and the clinical efficacy were compared between the two groups. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for comparison between groups; Chi-square test was used for comparison of enumeration data between groups. Results:After treatment, the 72 h urine urine pad usage in the observation group [(1.95±1.13) pieces] was lower than that in the control group [(6.28±2.47) pieces], and the difference was statistically significant ( P<0.05). After treatment, the maximum flow rate [(13.92±2.53) mL/s], maximum cystometric capacity [(338.72±19.22) mL], maximum urethral closure pressure [(69.75±5.04) cmH 2O], abdominal leakage point pressure [(90.56±5.26) cmH 2O] in observation group after treatment were better than those in control group [(11.48±2.18) mL/s, (325.81±18.63) mL, (65.29±4.78) cmH 2O, (83.58±5.29) cmH 2O], the difference were statistically significant ( P<0.05). After treatment, the ICI-Q-SF score of the observation group [(5.97±1.82) points] was lower than that of the control group [(10.95±2.64) points], and the difference was statistically significant ( P<0.05); the clinical effective rate of observation group (93.33%) was higher than that of control group (78.33%), and the difference was statistically significant ( P<0.05). Conclusion:PFMT combined with TENS is better than PFMT alone in the treatment of postoperative urinary incontinence after radical prostatectomy.

Objective:To evaluate the strategy and skills of reoperation for recurrent carcinoma at the stoma of esophagojejunostomy after total gastrectomy.Methods:The management experience in 18 patients at the Department of General Surgery, Tumor Hospital of Zhengzhou University from Oct 2016 to Jul 2021 were analyzed retrospectively.Results:Thirteen patients underwent left thoracoabdominal combined incision to completely remove the tumor.One patient developed anastomotic leakage, two patients developed pulmonary infection, one patient developed costochondritis, all were cured and discharged after conservative treatment; Nine patients had no postoperative complications. Two patients abandoned surgery due to high position of the tumor, 3 patients due to poor cardiopulmonary function, and were given radiotherapy and chemotherapy.The postoperative follow-up period was 4.6 to 42.9 months. Four patients died of tumor recurrence, and the remaining patients survived until the end of the follow-up. The overall 1-and 3-year recurrence-free survival rates were 100% and 20%, respectively.Conclusion:Surgery on recurrent carcinoma at esophagojejunostomy stoma after total gastrectomy, although difficult and challenging,could still benefit most patients when at the hands of expertise.

Objective:To investigate the clinical symptoms and cone-beam CT (CBCT) imaging characteristics of temporomandibular joint osteoarthritis (TMJOA) with chewing side preference (CSP).Methods:One hundred patients with TMJOA diagnosed in the Department of Stomatology, General Hospital of the Chinese PLA from January 2018 to December 2020 were enrolled, including 32 males and 68 females, with an median age of 27.5 years (16-71 years). According to the habit of CSP, 100 cases were divided into 71 cases of TMJOA with CSP group and 29 cases of TMJOA without CSP group. The clinical symptoms were observed, including pain, TMJ sounds, limited mouth opening as well as the radiograph imaging changes of condylar bone. When analyzing the radiograph imaging changes of condylar, the cases with bilateral TMJ symptoms were excluded and the remaining cases were divided into symptomatic sides and asymptomatic sides with CSP or without CSP according to the symptoms of the chief complaint. SPSS 25.0 was used to analyze the statistical data. Age data did not conform to normal distribution so that median and quartile spacing were used for description, and Mann-Whitney U test was used for nonparametric test. Qualitative data such as gender, clinical symptoms and condylar lesion types were described by composition ratio and chi-square test was performed. Results:There was no statistical significance in age and gender of TMJOA patients in the group with or without CSP ( P>0.05). The incidence of pain in CSP group [83.1% (59/71)] was marginally higher than that in non-CSP group [65.5% (19/29)] but without statistical difference (χ2 =3.71, P=0.054). There was also no significant difference in TMJ sounds and limitation of mandibular movement between the two groups (χ2 =0.11, P=0.742; χ2 =0.48, P=0.489). Among all of joints, the most common types of TMJOA were articular flattening and shortening and erosion. CBCT showed that erosion [65.0% (130/200)], flattening and shortening [73.0% (146/200)], subcortical sclerosis [42.0% (84/200)], osteophyte [30.5% (61/200)] and subcortical cystic [15.5% (31/200)]. According to the different groups of chief complaint sides, intra-group comparisons show that the proportion of erosion in symptomatic sides of CSP group [80.0% (40/50)] was significantly higher than that in asymptomatic sides of CSP group [50.0% (25/50)] (χ2=9.89, P=0.002). Inter-group comparisons show that the proportion of condyle flattening and shortening in symptomatic sides of CSP group [84.0% (42/50)] was significantly higher than that in bilateral joint of non-CSP group (8/15) (χ2=8.81, P=0.032). There was no significant difference in the proportion of subcortical sclerosis, osteophyte and subcortical cystic between the group with or without CSP ( P>0.05). Conclusions:TMJOA patients with CSP may be more prone to clinical symptoms of pain and CBCT imaging changes of condyle erosion as well as flattening and shortening. CSP may be a promoting factor for the development of TMJOA.

Specnuezhenide(SNZ)is among the main components of Fructus Ligustri Lucidi,which has anti-inflammation,anti-oxidation,and anti-tumor effect.The low bioavailability makes it difficult to explain the mechanism of pharmacological effect of SNZ.In this study,the role of the gut microbiota in the metabolism and pharmacokinetics characteristics of SNZ as well as the pharmacological meaning were explored.SNZ can be rapidly metabolized by the gut microbiome,and two intestinal bacterial metabolites of SNZ,salidroside and tyrosol,were discovered.In addition,carboxylesterase may be the main intestinal bacterial enzyme that mediates its metabolism.At the same time,no metabolism was found in the incubation system of SNZ with liver microsomes or liver homogenate,indicating that the gut microbiota is the main part involved in the metabolism of SNZ.In addition,pharmacokinetic studies showed that salidroside and tyrosol can be detected in plasma in the presence of gut microbiota.Interestingly,tumor development was inhibited in a colorectal tumor mice model administered orally with SNZ,which indicated that SNZ exhibited potential to inhibit tumor growth,and tissue distribution studies showed that salidroside and tyrosol could be distributed in tumor tissues.At the same time,SNZ modulated the structure of gut microbiota and fungal group,which may be the mechanism governing the antitumoral activity of SNZ.Furthermore,SNZ stimulates the secretion of short-chain fatty acids by intestinal flora in vitro and in vivo.In the future,targeting gut microbes and the interaction between natural products and gut microbes could lead to the discovery and development of new drugs.
