Objective:To analyze the clinicopathological characteristics of patients with unknown etiology of portal hypertension and investigate the efficacy of endoscopic management of gastroesophageal varices in these patients.Methods:Patients with unknown etiology of portal hypertension and gastroesophageal varices who received liver biopsy between January, 2017 and January, 2020 in Zhongshan Hospital were included. The characteristics of pathology, portal computed tomography (CT) angiography, and endoscopy were recorded and follow-up for the occurrence of bleeding after treatment.Results:A total of 31 patients were included and divided into cirrhosis with unknown etiology group ( n=10) and non-cirrhotic portal hypertension group ( n=21). Patients in the non-cirrhotic group were younger [28.0(29.5-49.5) vs 58.5(43.5-65.8), P=0.004] and mostly male (71.4%), and fewer comorbidities including diabetes (4.8% vs 40.0%, P=0.027). The features of pathology finding including vasculopathy, cholestasis, and hepatic sinusoidal dilatation as well as the Sarin classification and bleeding rate of gastroesophageal varices, proportion of patients receiving endoscopic treatment were shown similar between the two groups ( P>0.05). The hepatic venous pressure gradient (HVPG) was significantly lower in the non-cirrhotic group [4.5(2.8-12.8)mmHg vs 12(8-18)mmHg, P=0.018]. Among them, 21 patients received endoscopic treatment, and the bleeding rate had no difference between these two groups after endoscopic treatment ( P=0.751). Conclusions:Non-cirrhotic portal hypertension in a predominantly young male population has similar clinicalpathological characteristics when compared to cirrhotic portal hypertension with unknown etiology. HVPG can not reflect the actual portal pressure in these patients. Endoscopic treatment is the effective treatment option for the prevention of variceal bleeding.

OBJECTIVE:
To determine the most appropriate form of selective neck dissection(SND) in the hypopharyngeal cancer with cervical lymph node metastasis.
METHOD:
We have retrospectively analyzed the distribution and prevalence of cervical metastasis in 26 patients with hypopharyngeal squamous cell carcinoma from January 1998 to December 2008. All the patients underwent SND as part of the primary treatment. There were 34 elective SNDs and 17 therapeutic SNDs from 11 node-negative hypopharyngeal cancers and others node-positive.
RESULT:
Occult metastasis was found in 6 patients (55%) with cervical metastasis confined to level II and III. Clinical node-positive necks were all pathologically identified with 6.7%, 66.7%, 86.7%, 46.7%, and 20.0% of the prevalence of metastasis to level I, II, III, IV and V respectively. The regional recurrences were found in 4 patients during the follow-up, which were all from cN+ patients. No patient experienced level I recurrence.
CONCLUSION
The results of this study suggest that SND (I-III) may be feasible for the treatment of cN0 hypopharyngeal cancer, which needs a larger sample to verify. Meanwhile, from our data, it has a satisfactory result to perform SND (II-V) with adjuvant radiotherapy for the cN+ patients.

OBJECTIVETo investigate the safety and efficacy of organ preservation surgery or "watch and wait" strategy for rectal cancer patients who are evaluated as clinical complete response(cCR) or near-cCR following neoadjuvant chemoradiotherapy (nCRT).
METHODFrom March 2011 to June 2016, 35 patients with mid-low rectal cancers who were diagnosed as cCR or near-cCR following nCRT underwent organ preservation surgery with local excision or surveillance following "watch and wait" strategy in the Peking University Cancer Hospital. All the patients received re-evaluation and re-staging 6-12 weeks after the completion of nCRT, according to Habr-Gama and MSKCC criteria for the diagnosis of cCR or near-cCR. The near-cCR patients who received local excision and were pathologically diagnosed as T0Nx were also regarded as cCR. The end-points of this study included organ-preservation rate (OPR), sphincter-preservation rate (SPR), non-re-growth disease-free survival (NR-DFS), stoma-free survival, cancer-specific survival (CSS) and overall survival(OS). Kaplan-Meier curve was used to estimate the survival data at 3 years.
RESULTSA total of 35 cases were analyzed including 24 males (68.6%) and 11 females (31.4%). The median age was 60 (range 37-79) years and the median distance from tumor to anal edge was 4(2-8) cm. Thirty-three patients received 50.6 Gy/22f IMRT with capecitabine and two patients received 50 Gy/25f RT with capecitabine. The cCR and near-cCR rates were 74.3%(26/35) and 25.7%(9/35) respectively. Excision biopsy was performed in 4 near-cCR cases to confirm the diagnosis of cCR. The non-re-growth DFS rate was 14.3%(5/35) and the median time of tumor re-growth was 6.7 (4.7-37.4) months. In five patients with tumor re-growth, four were salvaged by radical rectal resections and one received local excision. The distant metastasis rate was 5.7%(2/35), one patient presented resectable liver metastasis and received radical resection, another patient presented multiple bone metastases and was still alive. The median follow-up time was 43.7(6.1-71.4) months. At three years, the organ-preservation rate was 88.6%(31/35), the sphincter-preservation rate was 97.1% (34/35). No local recurrence was observed in five patients who received salvage surgery. The non-re-growth DFS was 94.0%. Three patients died of non-rectal cancer related events. The cancer-specific survival was 100%, the overall survival was 92.7% and the stoma-free survival rate was 90.0%.
CONCLUSIONSOrgan preservation surgery or "watch and wait" strategy for cCR or near-cCR patients is feasible and achieves good outcomes. This strategy can be an alternative to standard care, improve patient's quality of life and facilitate tailored treatment for mid-low rectal cancer following nCRT, however, it should be cautiously applied in near-cCR patients before local excision biopsy.

Orthodontically induced tooth root resorption (OIRR) is a serious complication during orthodontic treatment. Stimulating cementum repair is the fundamental approach for the treatment of OIRR. Parathyroid hormone (PTH) might be a potential therapeutic agent for OIRR, but its effects still lack direct evidence, and the underlying mechanisms remain unclear. This study aims to explore the potential involvement of long noncoding RNAs (lncRNAs) in mediating the anabolic effects of intermittent PTH and contributing to cementum repair, as identifying lncRNA-disease associations can provide valuable insights for disease diagnosis and treatment. Here, we showed that intermittent PTH regulates cell proliferation and mineralization in immortalized murine cementoblast OCCM-30 via the regulation of the Wnt pathway. In vivo, daily administration of PTH is sufficient to accelerate root regeneration by locally inhibiting Wnt/β-catenin signaling. Through RNA microarray analysis, lncRNA LITTIP (LGR6 intergenic transcript under intermittent PTH) is identified as a key regulator of cementogenesis under intermittent PTH. Chromatin isolation by RNA purification (ChIRP) and RNA immunoprecipitation (RIP) assays revealed that LITTIP binds to mRNA of leucine-rich repeat-containing G-protein coupled receptor 6 (LGR6) and heterogeneous nuclear ribonucleoprotein K (HnRNPK) protein. Further co-transfection experiments confirmed that LITTIP plays a structural role in the formation of the LITTIP/Lgr6/HnRNPK complex. Moreover, LITTIP is able to promote the expression of LGR6 via the RNA-binding protein HnRNPK. Collectively, our results indicate that the intermittent PTH administration accelerates root regeneration via inhibiting Wnt pathway. The lncRNA LITTIP is identified to negatively regulate cementogenesis, which activates Wnt/β-catenin signaling via high expression of LGR6 promoted by HnRNPK.

OBJECTIVE:
To investigate the long-term outcome of organ preservation with local excision or "watch and wait" strategy for mid-low rectal cancer patients evaluated as clinical complete remission (cCR) or near-cCR following neoadjuvant chemoradiotherapy (NCRT).
METHODS:
Clinical data of 62 mid-low rectal cancer patients evaluated as cCR/near-cCR after NCRT undergoing organ preservation surgery with local excision or receiving "watch and wait" strategy at Department of Gastrointestinal Surgery, Peking University Cancer Hospital and Institute from March 2011 to August 2017 were retrospectively analyzed. According to the approximate 1:2 pairing, 123 patients who underwent radical resection with complete pathological remission(ypCR) after neoadjuvant chemotherapy during the same period were selected for prognosis comparison. The primary endpoint of the study was 3-year non-regrowth disease-free survival (NR-DFS) and tumor specific survival (CSS). Survival analysis was performed using the Kaplan-Meier curve (Log-rank method). The secondary endpoint of the study was 3-year organ preservation and sphincter preservation.
RESULTS:
The retrospective study included 38 male and 24 female patients. The median age was 60 (31-79) years and the median distance from tumor to anal verge was 4(1-8) cm. The ratio of cCR and near-cCR was 79.0%(49/62) and 21.0%(13/62) respectively. Local regrowth rate was 24.2%(15/62). Of 15 with tumor regrowth, 9 patients received salvage radical rectal resection and no local recurrence was found during follow-up; 4 patients received salvage local excision among whom one patient had a local recurrence occurred patient; 2 patients refused further surgery. The overall metastasis rate was 8.1%(5/62), including resectable metastasis(4.8%,3/62) and unresectable metastasis (3.2%,2/62). The valid 3-year organ preservation rate and sphincter preservation rate were 85.5%(53/62) and 95.2%(59/62) respectively. The median follow-up was 36.2(8.6-89.0) months. The 3-year NR-DFS of patients with cCR and near-cCR was 88.6% and 83.1% respectively, which was not significantly different to that of patients with ypCR (94.7%, P=0.217). The 3-year CSS of patients with cCR and near-cCR was both 100%, which was not significantly different to that of patients with ypCR(93.4%, P=0.186).
CONCLUSIONS
Mid-low rectal cancer patients with cCR or near-cCR after NCRT undergoing organ preservation with local excision or receiving "watch and wait" strategy have good long-term prognosis with low rates of local tumor regrowth and distant metastasis, which is similar to those with ypCR after radical surgery. This treatment mode may be used as an option for organ preservation in mid-low rectal cancer patients with good tumor remission after NCRT.
