Abstract
Objective: To investigate the clinicopathological, immunophenotypic, and genetic features of malignant peripheral nerve sheath tumor (MPNST). Methods: Twenty-three cases of MPNST were diagnosed at the Jiangsu Province Hospital (the First Affiliated Hospital of Nanjing Medical University), China, between January 2012 and December 2022 and thus included in the study. EnVision immunostaining and next-generation sequencing (NGS) were used to examine their immunophenotypical characteristics and genomic aberrations, respectively. Results: There were 10 males and 13 females, with an age range of 11 to 79 years (median 36 years), including 14 cases of neurofibromatosis type I-associated MPNST and 9 cases of sporadic MPNST. The tumors were located in extremities (7 cases), trunk (4 cases), neck and shoulder (3 cases), chest cavity (3 cases), paraspinal area (2 cases), abdominal cavity (2 cases), retroperitoneum (1 case), and pelvic cavity (1 case). Morphologically, the tumors were composed of dense spindle cells arranged in fascicles. Periphery neurofibroma-like pattern was found in 73.9% (17/23) of the cases. Under low magnification, alternating hypercellular and hypocellular areas resembled marbled appearance. Under high power, the tumor cell nuclei were irregular, presenting with oval, conical, comma-like, bullet-like or wavy contour. In 7 cases, the tumor cells demonstrated marked cytological pleomorphism and rare giant tumor cells. The mitotic figures were commonly not less than 3/10 HPF, and geographic necrosis was often noted. Immunohistochemically, tumor cells were positive for S-100 (14/23, 60.9%) and SOX10 (11/23, 47.8%). The loss of the CD34-positive fibroblastic network encountered in neurofibromas was observed in 14/17 of the MPNST cases. The loss of H3K27me3 expression was observed in 82.6% (19/23) of the cases. Moreover, SDHA and SDHB losses were presented in one case. NGS revealed that NF1 gene loss of function (germline or somatic) were found in all 5 cases tested. Furthermore, four cases accompanied with somatic mutations of SUZ12 gene and half of them had somatic mutations of TP53 gene, while one case with germline mutation in SDHA gene and somatic mutations in FAT1, BRAF, and KRAS genes. Available clinical follow-up was obtained in 19 cases and ranged from 1 to 67 months. Four patients died of the disease, all of whom had the clinical history of neurofibromatosis type Ⅰ. Conclusions: MPNST is difficult to be differentiated from a variety of spindle cell tumors due to its wide spectrum of histological morphology and complex genetic changes. H3K27me3 is a useful diagnostic marker, while the loss of CD34 positive fibroblastic network can also be a diagnostic feature of MPNST. NF1 gene inactivation mutations and complete loss of PRC2 activity are the common molecular diagnostic features, but other less commonly recurred genomic aberrations might also contribute to the MPNST pathogenesis.

Abstract
Primary lesion removal and lymph node dissection are the main constituents of radical gastrectomy. However, the high recurrence rate after D2 radical gastrectomy for advanced gastric cancer has not improved. Recently, studies have found that discrete tumor deposits in the mesogastrium may be an important factor affecting the prognosis of gastric cancer after surgery. With the development of laparoscopic equipment, the ever-expanding "submicroscopic vision" makes it possible to completely remove the mesogastrium. Professor Gong Jianping advocated "membrane anatomy" to optimize the concept of radical gastrectomy: D2- based complete mesenteric resection (CME), namely D2+CME procedure. To prevent the leakage of tumor cells into the surgical field, as histological barrier, the intact mesogastrium should be located. The essential difference between D2+CME and previous D2/D2+systematic mesogastrium excision (SME), en-bloc mesogastric excision (EME) is as follow: double-factor guiding (lymph nodes and discrete tumor deposits) vs. single factor guiding (lymph nodes only). After practicing dozens of radical gastrectomy (D2+CME) authors believe that its conceptual connotation (double factor guiding) and operational extension (above mesentery bed) cover D2. In D2+CME surgery, depending on the anatomical identification under the magnified field of view, the conformal space between gastric mesentery and mesenteric beds is unique operational plane with repeatability. These findings and considerations address one problem: where is the precise boundary of en bloc principle in radical gastrectomy? In author's opinion, with laparoscopy and "sub-microsurgery" progression and detection of discrete tumor deposit metastasis, survival benefit from definition of en bloc boundary in radical gastrectomy will be widely recognized. Meanwhile, D2+CME procedure is an appropriate way for study. Although the development of the "membrane anatomy" concept for gastric cancer still requires many further clinical and basic researches, it is reasonable to foresee that D2+CME surgery will guide a concept-optimized era for gastric cancer surgery.

Abstract
Objective: Data from the surveillance program was collected, to analyze the situation of hospitalization and cases of death with recorded causes, in Shenzhen, from 1995 to 2014. Situation of hospitalization and causes of deaths were studied in Shenzhen which had been a fast-developing city with growing number of immigrants so as to provide reference for decision-making on related prevention and control strategies. Methods: Data on hospitalizations and deaths collected from the surveillance program, were classified by both International Classification of Diseases (ICD)- 9 and ICD-10. A database was constructed with methods on related descriptive and trend analysis. Results: Around 6.3 million inpatients were seen in the past two decades in Shenzhen. The top five diseases for hospitalization were pregnancy childbirth and puerperium complications, respiratory diseases, injury and poisoning, digestive system diseases and circulatory system diseases, that accounting for 68.4% of all the hospitalization burden. The number of inpatients increased annually, with an 11 times increase during the past two decades. Proportions for pregnancy childbirth and puerperium complications, circulatory system diseases and urinary system diseases all showed increasing (χ(2)=53 806.94, 6 893.95 and 15 383.14, P<0.01), while proportions for injuries and poisoning, respiratory diseases, digestive system diseases showed a declining trend (χ(2)=131 480.09,1 711.84 and 11 367.66, P<0.01). Number of cumulative inpatient deaths exceeded 60 000, with the top five causes as malignant tumor, circulatory system diseases, injury and poisoning, respiratory system diseases and digestive system diseases, that accounting for 82.28% of all the inpatient deaths. Deaths due to circulatory system diseases, injury and poisoning increased and then decreased. Malignant tumor and respiratory diseases-induced deaths showed an increasing trend (χ(2)=1 546.48, 309.55, P<0.01), while induced deaths from disease of the other systems showed slight changes. The overall case fatality rate showed an annual decline (χ(2)=4 378.63, P<0.01), from 2.23% in 1995 to 0.74% in 2014, with mortality attribute to tumor, circulatory system disease decreased significantly. Conclusions: Shenzhen had been under an ageing transition, with relatively young population living in the city. Chronic diseases such as tumor gradually had become the major causes for heavy hospitalization burden on the population of Shenzhen.

Abstract
Radiation therapy is the first choice for the treatment of nasopharyngeal carcinoma. However, it is inevitable that nasopharyngeal mucosa and tissue will be damaged after radiotherapy of nasopharyngeal carcinoma, which will cause corresponding complications. Nasopharyngeal osteonecrosis is a serious complication. Up to now, there are few reports about nasopharyngeal osteonecrosis, and the underlaying pathological mechanism remains unclear. The potential theories include radiotherapy damage, infection and trauma, but also the " three H" principle of hypoxic hypocellular hypovascular tissue, as well as the theory of radio induced fibrosis. It is controversial about the treatment of nasopharyngeal osteonecrosis. It takes comprehensive treatment, including local treatment, systemic treatment, surgical treatment and other treatments. Among them, local treatment as nasopharyngeal debridement usually is first choice. We reviewed the pathological mechanism and treatment methods of nasopharyngeal osteonecrosis, in order to provide a reference for better prevention and treatment of it.

Abstract
During the early years of the People's Republic of China, sexually transmitted diseases (STD) were almost eliminated nationwide for a period. In the STDs eradication campaign, "political correctness" became a ruling policy. During the prevention and treatment of the STDs, the choice of therapy depended on the "political correctness" policy rather than medical effectiveness. With this political background, three competing treatments of STDs emerged (especially for syphilis): penicillin treatment, arsenic and bismuth mixed and intermittent treatment, and traditional Chinese medicine treatments. The argument between treatments was a vivid microcosm of the love-hate political relationship between China and the Union of Soviet Socialist Republics (USSR). The traditional Chinese medicine treatments for syphilis were used as a tool by the authorities to prevent the national medical system becoming more and more westernized. The penicillin treatment, the winner of this battle, won because it catered to the political themes of the time, the "Great Leap Forward" . Overwhelming state power had a strong influence and control over the medical system and medical practice, with the initiative and independence of doctors being limited in an unprecedented fashion.

Abstract
The monoamine serotonin (5-hydroxytryptamine, 5-HT), a well-known neurotransmitter,
also has important functions outside the central nervous system. The objective of
this study was to investigate the role of 5-HT in the proliferation, differentiation,
and function of osteoblasts in vitro. We treated rat primary
calvarial osteoblasts with various concentrations of 5-HT (1 nM to 10 µM) and
assessed the rate of osteoblast proliferation, expression levels of
osteoblast-specific proteins and genes, and the ability to form mineralized nodules.
Next, we detected which 5-HT receptor subtypes were expressed in rat osteoblasts at
different stages of osteoblast differentiation. We found that 5-HT could inhibit
osteoblast proliferation, differentiation, and mineralization at low concentrations,
but this inhibitory effect was mitigated at relatively high concentrations. Six of
the 5-HT receptor subtypes (5-HT1A, 5-HT1B, 5-HT1D,
5-HT2A, 5-HT2B, and 5-HT2C) were found to exist
in rat osteoblasts. Of these, 5-HT2A and 5-HT1B receptors had
the highest expression levels, at both early and late stages of differentiation. Our
results indicated that 5-HT can regulate osteoblast proliferation and function
in vitro.

Abstract
We sought to determine the dissemination of gastric cancer cells before and after radical D2 surgery and to determine the effectiveness of EIPL in preventing post-operative peritoneal metastasis. 64 patients were recruited with advanced gastric cancer for our final analysis. Complete curative gastrectomy with D2 lymphadenectomy was performed on the 64 patients. Before surgery, peritoneal lavage fluid was collected for cytological analysis by cell smearing and immunohistochemistry to detect disseminated cancer cells (S1). Following tumor and lymph node resection, peritoneal lavage fluid was collected for cytological examination (S2). The patients were treated by extensive intra-operative peritoneal lavage (EIPL) with normal saline (n = 31) or distilled water (n = 33). The peritoneal lavage fluid was collected for cytological examination (S3). At S1 stage, 18 patients (28.1%) were positive for disseminated cancer cells in their abdominal fluid. After D2 lymphadenectomy, 34 patients (53.1%) had disseminated cancer cells in their abdominal fluid at stage S2, which indicated that the D2 lymphadenectomy caused in an additional 16 (16/46, 34.8%) patients positive for disseminated cancer cells. After EIPL with either normal saline or distilled water at the S3 stage), all the patients were negative for disseminated cancer cells in their abdominal fluid. A total of six patients died, and four patients had recurrencent cancer. These findings indicate that D2 lymphadenectomy can disseminate gastric cancer cells, and post-operative lavage of the abdominal cavity can eliminate cancer cell dissemination and decrease the risk of peritoneal metastasis.

Abstract
The authors describe digital processing of mammographic images based on simulation of the procedure performed by radiologists to analyse radiographs. Image processing allows automatically enhancing contrasts and expressing them as a range of different light intensities and colors. Minimum contrast differences that are difficult to perceive with the bare eye are thus highly enhanced. This processing of mammographic images has proved useful not only to detect discrete lesions, but also to differentiate benign and malignant lesions.
